Definitions
- the present invention is in the medical device field, and more particularly relates to a pedal-actuated device to prevent development of deep venous thrombosis (DVT).
- DVD deep venous thrombosis
- DVT has been of concern in situations where people are immobile for relatively long periods, such as after surgery, or during long airplane flights.
- muscle contraction in the leg sends blood back to the heart, through the veins.
- the lower limbs tend to swell with stationary blood, and a clot may develop.
- Such clots can be very dangerous, resulting in life-threatening situations such as pulmonary embolisms, aneurisms, strokes, heart attacks, etc., or less dramatic, but long lasting disabilities of various sorts, as a result of clotted blood adhering to vein walls.
- footwear pump foot pump
- the apparatus applies an oscillatory movement to the ball of the foot so as to exercise the calf muscle and thereby prevent development of deep venous thrombosis.
- the apparatus is placed under the lower leg of the patient, who is lying down, and the weight of the leg serves to locate the apparatus without the need to strap the leg to the apparatus or to fasten the apparatus to the bed or table that the patient is lying on.
- the apparatus holds the leg in an optimally comfortable position, which position allows the lower leg muscle to go completely slack.
- This position allows the large vein in the leg to easily fill with blood, which is optimal for the functioning of the lower leg muscle to act as a pump.
- the foot motion is applied through a foot plate or pedal that is driven through a spring mechanism by an electric motor.
- the spring mechanism allows the plate to be stopped by foot resistance without stopping the motor, thereby preventing the apparatus from jamming the patient's foot.
- the apparatus may be adjusted so as to withdraw the motor drive, so that the patient may drive the plate by voluntarily flexing his or her own muscles, as a form of exercise.

- FIGS. 1 - 5 One particular embodiment of the invention is illustrated in FIGS. 1 - 5 , and is described in the text that follows.
- FIGS. 10 - 13 show additional embodiments and features of the invention.
- the invention has been most specifically illustrated with particular embodiments, its should be understood that the invention concerns the principles by which the claimed apparatus may be constructed, and is by no means limited to the specific embodiments shown.
- the first embodiment of the invention as referenced above comprises a monopedal anti-embolic device that facilitates the exercising of the lower leg, calf and foot muscles, while lying down.
- the device may be used by people convalescing in beds.
- One purpose of the invention is to attenuate the likelihood of the development of vascular emboli (and the consequences thereof) during long and extended periods of inactivity.
- This embodiment safely and easily facilitates the exercising of the lower leg by applying a preset amount of force to the bottom of the foot causing the foot to pivot at the ankle and stretch the calf muscle.
- This embodiment of the invention then reverses and allows the foot to hang freely from the ankle and thus allow the calf muscle to go slack.
- the invention may use the weight of the leg to locate itself with respect to the bed and thus locate the device in relation to the body, so that the device is not required to be strapped to the body of the patient or strapped or bolted to the bed frame (although in another embodiment, this device could be strapped to the leg or externally affixed to the bed, if desired).
- the invention also supports the leg in such a way as to prevent heel sores and, by supporting the leg in a slightly bent-knee manner, helps to align the foot to the pedal.
- This leg position is also optimal for the functioning of the lower leg muscle to act as a pump, because the weight of the leg is not resting on the calf muscle, and there is no support point or pressure in the area behind the knee joint.
- One embodiment of the invention has a vertically adjustable ankle support to accommodate different ankle shapes and diameters.
- the lower leg may be supported either at the ankle or higher up the leg, under the calf.
- Another embodiment of the invention has a sprung sliding member on the foot pedal so as to accommodate an incorrectly located ankle and help prevent the possible resultant friction burn.
- the invention can also be used unpowered as an exercise machine by setting a switch to the exercise pedal that will move it into its full compression position. In this case, the patient then simply pushes against the pedal causing the pedal and arm to move back and forth against the preset spring.
- the mechanism for one embodiment of the invention comprises a reversible motor, a geartrain providing a very slow final output to the arm and a torsion spring indirectly connecting the final output shaft of the geartrain to the arm.
- the final output shaft of the geartrain only engages the spring in its torqued direction so that in the backward direction of the geartrain the arm is not being pulled backward away from the foot but is only falling back with gravity. This safety feature ensures that the pedal is only driven in one direction and in that direction is only driven through the spring with a safe preset amount of force.
- FIG. 1 a is a side view of one embodiment of the invention, showing the various elements that comprise the invention, while FIG. 1 b shows the same side view of the apparatus with the patient's leg in position.
- the apparatus comprises a thigh pad 101 , an ankle pad 103 and a foot pedal 109 that is attached through an arm 107 to a drive mechanism 105 .
- the drive mechanism 105 momentarily applies a measured or preset amount of pressure to the bottom of the foot 123 of someone in the prone position so as to flex and extend the foot at the ankle 121 in order to tighten and release the calf muscles 117 .
- this embodiment of the apparatus comprises a thigh pad 101 and an ankle pad 103 to support the leg 119 in a slightly bent position so as to help locate the foot 123 and allow the foot 123 to hang freely.
- the slightly bent and elevated position of the leg 119 aside from being an ideal resting position for the leg, would also prevent bed sores on the back of the heel 125 .
- the thigh pad 101 and ankle pad 103 also sit on (or may be affixed to or slidably affixed to) the frame 115 of the device, thus using the weight of the leg 119 to anchor the device to the bed, without the need for attaching the device to the bed or table, or strapping the device to the patient.
- the drive mechanism 105 comprises a simple motor-driven device that puts a measured amount of pressure on the sole of the foot 123 causing the foot to pivot at the ankle 121 and stretch the calf muscle 117 .
- the device then reverses and allows the foot 123 to hang freely from the ankle 121 , thus allowing the calf muscle 117 to go slack.
- the device can only apply a preset amount of pressure to the bottom of the foot 123 because the arm 107 is spring loaded to the drive mechanism 105 , so even if a particular patient has a very limited range of motion the device will only apply a given amount of pressure to the bottom of the foot 123 and not try to force the foot 123 and ankle 121 beyond what it is capable of moving.
- FIG. 2 is a detailed view of the drive mechanism 105 .
- the mechanism comprises a reversible shaded pole alternating current (AC) motor (not shown), a geartrain (not shown) which reduces rotation to about one revolution per minute (RPM) final output to the arm 107 , and a torsion spring 203 indirectly connecting the final output shaft of the geartrain to the arm 107 .
- the motor is driven back and forth by limit switches on the final output shaft of the geartrain.
- the final output shaft rotates backward and forward about 70 degrees.
- the mechanism is supported through frame members 208 .
- the final output shaft of the geartrain is indirectly connected to the arm 107 through the torsion spring 203 .
- the arm 107 with foot pad attached (not shown) is affixed to the output flanged shaft 205 by a pin 213 .
- One end of the torsion spring 203 is connected to the arm 107 , and the other end is torqued against a stop that is also connected to the arm 107 .
- This means the spring 203 always has some preset torque on it (in one embodiment, this preset torque is preferably approximately fifty in-lb) so that as soon as the device engages, the foot 123 is engaging the foot pad 109 with, in this preferred case, approximately fifty in-lb of torque.
- the arm 107 can be pushed backwards with slightly increasing force as the spring 203 is wound tighter.
- the output of the motor/geartrain is connected to the input flanged shaft 202 and transmitted to the torsion spring 203 only in the counterclockwise direction through pin 206 that pushes against pin 207 .
- Pin 207 pushes against torsion spring 203 .
- the other end of torsion spring 203 pushes against pin 209 which is affixed to output flanged shaft 205 .
- torsion spring 203 The preload of torsion spring 203 is maintained by shaft 204 .
- Pin 210 is affixed to shaft 204 and stops pin 209 which in turn stops one end of the torsion spring 203 .
- Disk 211 is affixed to shaft 204 by pin 212 and stops the other end of the torsion spring 203 with pin 207 which is affixed to disk 211 .
- This arrangement allows for driving the output shaft 205 in only the counterclockwise direction and then only through the preloaded torsion spring 203 .
- Output flanged shaft 205 only rotates counterclockwise when either the foot pushes against arm 107 or the weight of arm 107 itself is over center enough to induce a clockwise torque on output flanged shaft 205 .
- the final output shaft of the geartrain only engages the spring 203 in its torqued direction so that in the backward direction of the geartrain the arm 107 is not being pulled backward away from the foot 123 but only falling back with gravity.
- the design of the mechanism completely isolates the geartrain and motor from misuse.
- the geartrain and motor can only have the preset torque of the spring 203 applied to it.
- This design is also safe for the user because it only applies a preset amount of pressure to the bottom of the foot 123 no matter how badly misaligned the device is to the foot/leg/body of the user.
- the arm 107 In the release or backward stroke the arm 107 is not driven, allowing the arm 107 to stop if it encounters any resistance. For example, if the foot 123 slips off the pedal 109 , the motor will not drive the pedal 109 against the top of the foot 123 .
- FIG. 3 shows a detailed view of the foot pedal and pad of the invention.
- the foot pedal 109 is attached to the arm 301 through two fasteners 309 .
- the foot pad 303 is on the side of the foot pedal 109 that engages the bottom of the foot 123 .
- the foot pad 303 is attached to the foot pedal 109 through two vertical slots 307 with a spring 309 . These slots allow the foot pad 303 to slide up and down on the foot pedal 109 so as to accommodate an incorrectly located ankle and to help prevent possible resultant friction on the bottom of the foot.
- FIG. 4 illustrates two different operating modes of the invention.
- the apparatus comprises a switch for the motor with three positions: Off, On and Exercise.
- the switch in position 1 (Off)
- the motor causes the arm 107 to be angled down away from the foot, exerting no pressure on the foot, allowing the foot to hang freely.
- the switch in position 2 (On) (not shown)
- the motor causes the arm to move back and forth slowly from close to vertical (maximum pressure on foot), to close to horizontal (foot hanging freely).
- the switch in position 3 (Exercise), as shown in FIG. 4 a , the motor causes the arm 107 to be close to vertical (maximum pressure).
- this preset amount of resistance is approximately 50 in-lb of torque.
- FIG. 5 shows an alternate embodiment of the ankle pad, allowing vertical adjustment of the pad to allow better alignment of the ankle with the pivot axis of the arm.
- the pad 501 is attached through a threaded support member 502 to the support frame 504 using a threaded rod 503 .
- the support member is kept from turning by a rod 505 that fits through a hole in the support member 502 and is attached to the support frame 504 .
- Turning the threaded rod 503 causes the support member 502 to slide up or down on the rod 505 , allowing the pad 501 to be adjusted to the optimum vertical height.
- each monopedal half of the invention comprises a thigh pad 601 with an adjustable connecting rod 621 .
- a frame 615 supports drive portion of the device, including drive mechanism 605 and ankle pad 603 (which may be vertically adjustable, and which may also be slidably affixed to the support frame 615 ).
- the drive mechanism 605 is connected through an arm 607 to a foot pedal 609 .
- a foot pad (not shown) may be slidably attached to foot pedal 609 to allow the foot pad to slide up and down on the foot pedal 609 so as to accommodate an incorrectly located ankle and to help prevent possible resultant friction on the bottom of the foot.
- the thigh pad 601 in this embodiment may be lengthwise adjustably connected to the support frame 615 , for example through telescoping tubes 623 . Two thigh pads 601 can be connected to each other using adjustable connecting rod 621 , resulting in a bipedal apparatus.
- an adjustable connection may be made between support frames 615 , in place of or in addition to an attachment between thigh pads 601 , to provide additional stability and/or to help maintain the correct distance between the two halves of the bipedal apparatus.
- FIG. 7 and FIG. 8 a show detailed views of thigh pad 601 and adjustable connecting rod 621 of the bipedal embodiment shown in FIG. 6.
- adjustable connecting rod 621 is affixed to thigh pad 601 such that connecting rod 621 may be placed in a variety of positions, depending upon the particular configuration of the apparatus desired.
- connecting rod 621 a is placed in a “stored” position, lying along thigh pad 601 so that the longitudinal axis of connecting rod 621 is generally parallel to the lengthwise direction of the apparatus.
- connecting rod 621 may be simply detached from thigh pad 601 , or may slide into a hole in thigh pad 601 for storage.
- connecting rod 621 swings through position 621 b and is placed in “connection” position 621 c , projecting outward from thigh pad 601 in the direction of a second thigh pad (not shown).
- the connecting rod of a second thigh pad is similarly (but oppositely) positioned to project out from second thigh pad toward first thigh pad 601 .
- Connecting rods e.g. 621 c
- Connecting rods are then affixed to each other for a bipedal embodiment.
- FIG. 8 a shows details of one embodiment of adjustable connecting rods for the bipedal embodiment described.
- two connecting rods 821 a and 821 b of two thigh pads 801 a and 801 b are slidably attached to each other.
- connecting rods 821 a and 821 b have attachment holes 823 along the longitudinal axes of both connecting rods 821 a and 821 b .
- connection means may be, for example, nut and bolt, pin, screw, or any other means that serves to affix connecting rods 821 a and 821 b to each other such that they are restrained from moving relative to each other and such that distance “d” between thigh pads 801 a and 801 b is maintained.
- Distance “d” is determined as appropriate according to the requirements of each individual patient, and may depend upon various factors, including the size of the patient or any injury that the patient may have suffered. For example, in patients with fractured hips or hip replacements, an abduction pillow as shown in FIG. 8 b is often kept between the patient's legs to prevent dislocation of the hip joint. Using the bipedal embodiment as described, thigh pads 801 a and 801 b may be adjusted to the correct distance “d” to maintain the patient's hip position and eliminate the need for an abduction pillow.

Abstract
A “soleus pump” (foot pump) applies an oscillatory movement to the sole of the foot so as to exercise the calf muscle and thereby prevent development of deep venous thrombosis. In one embodiment, the apparatus is placed under the lower leg of the patient, holding the leg in an optimal position without the necessity of strapping the apparatus to the patient or to the bed or table. The foot motion is applied through a foot pedal incorporating a safety feature which keeps the apparatus from jamming the patient's foot. In another operating mode, the motor drive may be withdrawn, so that the patient may drive the plate by voluntarily flexing the leg muscles, as a form of exercise. In another embodiment, two monopedal embodiments may be joined together to create a bipedal version of the invention, permitting both legs to be exercised at the same time. In yet another embodiment, the apparatus may be adapted for use by a patient sitting upright, for example, in a chair or airline seat.
Description
- This application claims benefit of U.S. provisional patent application serial no. 60/323,410, filed on Sep. 18, 2001.
- 1. Field of the Invention
- The present invention is in the medical device field, and more particularly relates to a pedal-actuated device to prevent development of deep venous thrombosis (DVT).
- 2. Description of Related Art
- DVT has been of concern in situations where people are immobile for relatively long periods, such as after surgery, or during long airplane flights. Generally, muscle contraction in the leg sends blood back to the heart, through the veins. If the muscles are not used for an extended period of time, the lower limbs tend to swell with stationary blood, and a clot may develop. Such clots can be very dangerous, resulting in life-threatening situations such as pulmonary embolisms, aneurisms, strokes, heart attacks, etc., or less dramatic, but long lasting disabilities of various sorts, as a result of clotted blood adhering to vein walls.
- Because of this potential danger, preventive measures against DVT are standard in postoperative care. A number of techniques have been developed. The current state of the art technique of choice for doing this is to employ an apparatus in the form of a cuff that slides over the leg, which provides an undulating compression to the calf muscle to help drive blood back to the heart. Among the drawbacks of the current cuff technology is the relatively high cost of the pumping apparatus for the cuff, and of the cuff itself, which must be disposed of after about three days of use. Another drawback is that the cuff is not usable if the leg is in a cast or has had incisions.
- In other existing techniques, the patient's foot is flexed in order to exercise the calf muscle. However, prior art versions of foot pumps have numerous disadvantages, including that they require the apparatus to be strapped to the patient's leg and to the bed or table; they don't hold the leg in an optimal position for allowing the lower leg muscle to act as a pump; and they apply pressure to the back of the knee joint or calf, thereby restricting blood flow in the lower leg. Thus, when these prior art versions release tension on the muscle, the weight of the leg is still on the muscle and vein. As a result, the vein in the leg is not allowed to easily or completely fill with blood, therefore producing a much less efficient pumping action.
- Accordingly, it is an object of the present invention to provide a more cost effective and versatile apparatus for preventing DVT than those currently available, consistent with other important objects including safety, comfort and ease of use. It is another object of the invention to provide both active and passive modes of operation, so that the patient can either allow the machine to provide the movement (passive), or supply the moving force himself or herself (active) as a form of exercise. It is a further object of the invention to provide an apparatus that holds the patient's leg in an optimally comfortable position, which position is also optimal for the function of the lower leg muscle to act as a pump.
- These and other objects of the invention are achieved with an apparatus we refer to as a “soleus pump” (foot pump), which, in one embodiment, applies an oscillatory movement to the ball of the foot so as to exercise the calf muscle and thereby prevent development of deep venous thrombosis. In this embodiment, the apparatus is placed under the lower leg of the patient, who is lying down, and the weight of the leg serves to locate the apparatus without the need to strap the leg to the apparatus or to fasten the apparatus to the bed or table that the patient is lying on. The apparatus holds the leg in an optimally comfortable position, which position allows the lower leg muscle to go completely slack. This position allows the large vein in the leg to easily fill with blood, which is optimal for the functioning of the lower leg muscle to act as a pump. The foot motion is applied through a foot plate or pedal that is driven through a spring mechanism by an electric motor. The spring mechanism allows the plate to be stopped by foot resistance without stopping the motor, thereby preventing the apparatus from jamming the patient's foot. In another operating mode, the apparatus may be adjusted so as to withdraw the motor drive, so that the patient may drive the plate by voluntarily flexing his or her own muscles, as a form of exercise.

- One particular embodiment of the invention is illustrated in FIGS.1-5, and is described in the text that follows. Other embodiments of the invention, showing adjustable monopedal and bipedal versions of the invention, are illustrated in FIGS. 6-9. FIGS. 10-13 show additional embodiments and features of the invention. Although the invention has been most specifically illustrated with particular embodiments, its should be understood that the invention concerns the principles by which the claimed apparatus may be constructed, and is by no means limited to the specific embodiments shown.
- The first embodiment of the invention as referenced above comprises a monopedal anti-embolic device that facilitates the exercising of the lower leg, calf and foot muscles, while lying down. The device may be used by people convalescing in beds. One purpose of the invention is to attenuate the likelihood of the development of vascular emboli (and the consequences thereof) during long and extended periods of inactivity.
- This embodiment safely and easily facilitates the exercising of the lower leg by applying a preset amount of force to the bottom of the foot causing the foot to pivot at the ankle and stretch the calf muscle. This embodiment of the invention then reverses and allows the foot to hang freely from the ankle and thus allow the calf muscle to go slack. The invention may use the weight of the leg to locate itself with respect to the bed and thus locate the device in relation to the body, so that the device is not required to be strapped to the body of the patient or strapped or bolted to the bed frame (although in another embodiment, this device could be strapped to the leg or externally affixed to the bed, if desired). The invention also supports the leg in such a way as to prevent heel sores and, by supporting the leg in a slightly bent-knee manner, helps to align the foot to the pedal. This leg position is also optimal for the functioning of the lower leg muscle to act as a pump, because the weight of the leg is not resting on the calf muscle, and there is no support point or pressure in the area behind the knee joint. One embodiment of the invention has a vertically adjustable ankle support to accommodate different ankle shapes and diameters. In other embodiments, the lower leg may be supported either at the ankle or higher up the leg, under the calf.
- Another embodiment of the invention has a sprung sliding member on the foot pedal so as to accommodate an incorrectly located ankle and help prevent the possible resultant friction burn. In another operating mode, the invention can also be used unpowered as an exercise machine by setting a switch to the exercise pedal that will move it into its full compression position. In this case, the patient then simply pushes against the pedal causing the pedal and arm to move back and forth against the preset spring.
- The mechanism for one embodiment of the invention comprises a reversible motor, a geartrain providing a very slow final output to the arm and a torsion spring indirectly connecting the final output shaft of the geartrain to the arm. The final output shaft of the geartrain only engages the spring in its torqued direction so that in the backward direction of the geartrain the arm is not being pulled backward away from the foot but is only falling back with gravity. This safety feature ensures that the pedal is only driven in one direction and in that direction is only driven through the spring with a safe preset amount of force.
- Any of the foregoing features and embodiments may also be incorporated in a bipedal embodiment of the invention, which would allow a patient to exercise both legs simultaneously, if desired.
- FIG. 1a is a side view of one embodiment of the invention, showing the various elements that comprise the invention, while FIG. 1b shows the same side view of the apparatus with the patient's leg in position. The apparatus comprises a
thigh pad 101, anankle pad 103 and afoot pedal 109 that is attached through anarm 107 to adrive mechanism 105. Thedrive mechanism 105 momentarily applies a measured or preset amount of pressure to the bottom of thefoot 123 of someone in the prone position so as to flex and extend the foot at theankle 121 in order to tighten and release thecalf muscles 117. - As shown in FIG. 1, this embodiment of the apparatus comprises a
thigh pad 101 and anankle pad 103 to support theleg 119 in a slightly bent position so as to help locate thefoot 123 and allow thefoot 123 to hang freely. The slightly bent and elevated position of theleg 119, aside from being an ideal resting position for the leg, would also prevent bed sores on the back of theheel 125. Thethigh pad 101 andankle pad 103 also sit on (or may be affixed to or slidably affixed to) theframe 115 of the device, thus using the weight of theleg 119 to anchor the device to the bed, without the need for attaching the device to the bed or table, or strapping the device to the patient. - The
drive mechanism 105 comprises a simple motor-driven device that puts a measured amount of pressure on the sole of thefoot 123 causing the foot to pivot at theankle 121 and stretch thecalf muscle 117. The device then reverses and allows thefoot 123 to hang freely from theankle 121, thus allowing thecalf muscle 117 to go slack. The device can only apply a preset amount of pressure to the bottom of thefoot 123 because thearm 107 is spring loaded to thedrive mechanism 105, so even if a particular patient has a very limited range of motion the device will only apply a given amount of pressure to the bottom of thefoot 123 and not try to force thefoot 123 andankle 121 beyond what it is capable of moving. - FIG. 2 is a detailed view of the
drive mechanism 105. In this embodiment, the mechanism comprises a reversible shaded pole alternating current (AC) motor (not shown), a geartrain (not shown) which reduces rotation to about one revolution per minute (RPM) final output to thearm 107, and atorsion spring 203 indirectly connecting the final output shaft of the geartrain to thearm 107. The motor is driven back and forth by limit switches on the final output shaft of the geartrain. The final output shaft rotates backward and forward about 70 degrees. The mechanism is supported throughframe members 208. - The final output shaft of the geartrain is indirectly connected to the
arm 107 through thetorsion spring 203. Thearm 107 with foot pad attached (not shown) is affixed to the outputflanged shaft 205 by apin 213. One end of thetorsion spring 203 is connected to thearm 107, and the other end is torqued against a stop that is also connected to thearm 107. This means thespring 203 always has some preset torque on it (in one embodiment, this preset torque is preferably approximately fifty in-lb) so that as soon as the device engages, thefoot 123 is engaging thefoot pad 109 with, in this preferred case, approximately fifty in-lb of torque. Thearm 107 can be pushed backwards with slightly increasing force as thespring 203 is wound tighter. - The output of the motor/geartrain is connected to the input
flanged shaft 202 and transmitted to thetorsion spring 203 only in the counterclockwise direction throughpin 206 that pushes againstpin 207.Pin 207 pushes againsttorsion spring 203. The other end oftorsion spring 203 pushes againstpin 209 which is affixed to outputflanged shaft 205. - The preload of
torsion spring 203 is maintained byshaft 204.Pin 210 is affixed toshaft 204 and stopspin 209 which in turn stops one end of thetorsion spring 203.Disk 211 is affixed toshaft 204 bypin 212 and stops the other end of thetorsion spring 203 withpin 207 which is affixed todisk 211. - This arrangement allows for driving the
output shaft 205 in only the counterclockwise direction and then only through thepreloaded torsion spring 203. Outputflanged shaft 205 only rotates counterclockwise when either the foot pushes againstarm 107 or the weight ofarm 107 itself is over center enough to induce a clockwise torque on outputflanged shaft 205. - As a safety feature, the final output shaft of the geartrain only engages the
spring 203 in its torqued direction so that in the backward direction of the geartrain thearm 107 is not being pulled backward away from thefoot 123 but only falling back with gravity. The design of the mechanism completely isolates the geartrain and motor from misuse. The geartrain and motor can only have the preset torque of thespring 203 applied to it. This design is also safe for the user because it only applies a preset amount of pressure to the bottom of thefoot 123 no matter how badly misaligned the device is to the foot/leg/body of the user. In the release or backward stroke thearm 107 is not driven, allowing thearm 107 to stop if it encounters any resistance. For example, if thefoot 123 slips off thepedal 109, the motor will not drive thepedal 109 against the top of thefoot 123. - FIG. 3 shows a detailed view of the foot pedal and pad of the invention. In this embodiment, the
foot pedal 109 is attached to the arm 301 through twofasteners 309. The foot pad 303 is on the side of thefoot pedal 109 that engages the bottom of thefoot 123. The foot pad 303 is attached to thefoot pedal 109 through twovertical slots 307 with aspring 309. These slots allow the foot pad 303 to slide up and down on thefoot pedal 109 so as to accommodate an incorrectly located ankle and to help prevent possible resultant friction on the bottom of the foot. - FIG. 4 illustrates two different operating modes of the invention. In one embodiment of the invention, the apparatus comprises a switch for the motor with three positions: Off, On and Exercise. With the switch in position1 (Off), as shown in FIG. 4b, the motor causes the
arm 107 to be angled down away from the foot, exerting no pressure on the foot, allowing the foot to hang freely. With the switch in position 2 (On) (not shown), the motor causes the arm to move back and forth slowly from close to vertical (maximum pressure on foot), to close to horizontal (foot hanging freely). With the switch in position 3 (Exercise), as shown in FIG. 4a, the motor causes thearm 107 to be close to vertical (maximum pressure). In this position, the user simply pushes against thefoot pad 109, causing the spring-loadedarm 107 to rotate backwards and forwards with a preset amount of resistance. In the presently preferred embodiment, this preset amount of resistance is approximately 50 in-lb of torque. - FIG. 5 shows an alternate embodiment of the ankle pad, allowing vertical adjustment of the pad to allow better alignment of the ankle with the pivot axis of the arm. In this embodiment, the
pad 501 is attached through a threadedsupport member 502 to thesupport frame 504 using a threadedrod 503. As the threadedrod 503 is turned, the support member is kept from turning by arod 505 that fits through a hole in thesupport member 502 and is attached to thesupport frame 504. Turning the threadedrod 503 causes thesupport member 502 to slide up or down on therod 505, allowing thepad 501 to be adjusted to the optimum vertical height. - In FIG. 6, two adjustable monopedal embodiments of the invention may be joined together to create a bipedal version of the invention, which permits both legs to be exercised at the same time, if desired, with a separate motor for each leg. In this embodiment, each monopedal half of the invention comprises a
thigh pad 601 with an adjustable connectingrod 621. A frame 615 supports drive portion of the device, includingdrive mechanism 605 and ankle pad 603 (which may be vertically adjustable, and which may also be slidably affixed to the support frame 615). Thedrive mechanism 605 is connected through anarm 607 to afoot pedal 609. A foot pad (not shown) may be slidably attached to foot pedal 609 to allow the foot pad to slide up and down on thefoot pedal 609 so as to accommodate an incorrectly located ankle and to help prevent possible resultant friction on the bottom of the foot. Thethigh pad 601 in this embodiment may be lengthwise adjustably connected to the support frame 615, for example throughtelescoping tubes 623. Twothigh pads 601 can be connected to each other using adjustable connectingrod 621, resulting in a bipedal apparatus. - In additional bipedal embodiments (not shown), an adjustable connection may be made between support frames615, in place of or in addition to an attachment between
thigh pads 601, to provide additional stability and/or to help maintain the correct distance between the two halves of the bipedal apparatus. - FIG. 7 and FIG. 8a show detailed views of
thigh pad 601 and adjustable connectingrod 621 of the bipedal embodiment shown in FIG. 6. In FIG. 7, adjustable connectingrod 621 is affixed tothigh pad 601 such that connectingrod 621 may be placed in a variety of positions, depending upon the particular configuration of the apparatus desired. In a monopedal embodiment, connectingrod 621 a is placed in a “stored” position, lying alongthigh pad 601 so that the longitudinal axis of connectingrod 621 is generally parallel to the lengthwise direction of the apparatus. In alternate monopedal embodiments (not shown), connectingrod 621 may be simply detached fromthigh pad 601, or may slide into a hole inthigh pad 601 for storage. To configure the apparatus for the bipedal embodiment as illustrated, connectingrod 621 swings through position 621 b and is placed in “connection”position 621 c, projecting outward fromthigh pad 601 in the direction of a second thigh pad (not shown). The connecting rod of a second thigh pad is similarly (but oppositely) positioned to project out from second thigh pad towardfirst thigh pad 601. Connecting rods (e.g. 621 c) are then affixed to each other for a bipedal embodiment. - FIG. 8a shows details of one embodiment of adjustable connecting rods for the bipedal embodiment described. In the embodiment shown in FIG. 8a, two connecting
rods 821 a and 821 b of two thigh pads 801 a and 801 b, respectively, are slidably attached to each other. In this embodiment, connectingrods 821 a and 821 b haveattachment holes 823 along the longitudinal axes of both connectingrods 821 a and 821 b. When thigh pads 801 a and 801 b are positioned a distance “d” apart, holes 823 of connectingrods 821 a and 821 b are aligned so that attachment means (not shown) can pass through alignedholes 823 of both connectingrods 821 a and 821 b, thus affixing connectingrod 821 a to connecting rod 821 b. Attachment means may be, for example, nut and bolt, pin, screw, or any other means that serves to affix connectingrods 821 a and 821 b to each other such that they are restrained from moving relative to each other and such that distance “d” between thigh pads 801 a and 801 b is maintained. - Distance “d” is determined as appropriate according to the requirements of each individual patient, and may depend upon various factors, including the size of the patient or any injury that the patient may have suffered. For example, in patients with fractured hips or hip replacements, an abduction pillow as shown in FIG. 8b is often kept between the patient's legs to prevent dislocation of the hip joint. Using the bipedal embodiment as described, thigh pads 801 a and 801 b may be adjusted to the correct distance “d” to maintain the patient's hip position and eliminate the need for an abduction pillow.
- As shown in FIG. 9, an additional embodiment of the invention comprises an adjustable connection between
thigh pad 901 and drivemechanism support frame 915, allowing the overall length of the apparatus to be adjusted to accommodate each particular patient's leg size. In the embodiment shown, the adjustable connection comprisestelescoping tubes 923 which may be slidably adjusted to a distance “1” so as to properly position the patient's thigh inthigh pad 901 and the ankle inankle pad 903. However, the invention is by no means limited to this particular embodiment, and the adjustable connection may be any means which allows the distance “1” to be maintained betweenthigh pad 901 andsupport frame 915. - The invention may also be adapted for use by patients in an upright, sitting position (for example, during a long airplane flight). In the embodiment shown in FIG. 10a, the patient is shown lying down with the leg located in the apparatus in the optimal knee-bent position, supported by
thigh pad 1001 andankle support 1003.Foot 123 rests againstfoot pedal 1009. In FIG. 10b,thigh pad 1001 andankle support 1003 are detached from the apparatus, and the position offoot pedal 1009 is adjusted to accommodatefoot 123 for a patient in the upright position. - As shown in the detailed view of FIG. 11a,
foot pedal 1009 has two positions in this embodiment: one for sitting and one for lying down. For the sitting position, ankle support 1003 (see FIG. 10a), which in this embodiment is attached through aslot 1027 inhousing 1029, may be detached from the apparatus. A flip-stand 1031 helps to positionfoot pedal 1009 for comfortable use in the sitting position. As shown in FIG. 11b, flip-stand 1031 rests againstunderside 1039 ofhousing 1029, but may be flipped out in the direction shown by arrow A to form a support which raises the front of the housing from the ground (see FIG. 10b and FIG. 11a). In this embodiment,ankle support 1003 is vertically adjustable usingheight adjustment control 1033, and the speed of the drive motor may be controlled by use of aspeed control dial 1035. Two monopedal versions of this embodiment may be joined together through an attachment bar (not shown) connected through tandem-bar socket 1037 to create a bipedal version. - Another embodiment of the invention is shown in a front view (FIG. 12a) and back view (FIG. 12b).
Foot pedal 1209 and verticallyadjustable ankle support 1203 are attached tohousing 1229. Vertical height of ankle support is adjusted throughheight adjustment control 1233, and motor may be controlled throughspeed control switch 1235.Thigh support 1201 is attached throughconnection rod 1223 to supportframe 1215. Length may be adjusted, orthigh pad 1201 andconnection rod 1223 may be detached fromsupport frame 1215, usingadjustment knob 1241. - In another embodiment, shown in FIG. 13a, the position of
foot pedal 1309 may be adjusted through aheight adjustment knob 1343. As shown in the detailed view of FIG. 13b, turningheight adjustment knob 1343 causesfoot pedal 1309 andmechanism 1349 to be raised or lowered along threadedrod 1345. As the height changes,mechanism 1349 rotates atpivot point 1347, andfoot pedal 1309, which is attached tomechanism 1349, changes position. - Other embodiments or variations are possible without going beyond the scope of the invention as described herein. For example, the invention could be adapted to a different bipedal version that would work similarly to the monopedal embodiment as shown in FIG. 1, having a single motor driving two pedals either in a parallel fashion or in an opposing fashion (one pedal up, one down). Another type of reversible motor could be used, or even a nonreversing motor, driving the arm back and forth through a crank. The embodiment as shown in FIG. 10b could be adapted to attach to the back of a seat in an airplane, train, bus, car or other conveyance for use by travelers. An embodiment in which the motor is replaced by a pneumatic pump is possible, where the pneumatic pump supplies energy to the drive mechanism as required. The spring provides an optional exercise function and a safety factor. The exercise function would be excluded and the safety factor accomplished by either a torque-limiting device or a torque- or power-sensing circuit. The pivoting arm with the pad on it could be replaced by an arced piston or arced member with gear teeth on it that would move in and out of a device, but still roughly match the motion of the foot being rotated about the ankle.
- It is apparent from the foregoing that the present invention achieves the specified objects, as well as the other objectives outlined herein. While currently preferred embodiments of the invention have been described in detail, it will be apparent to those skilled in the art that the principles of the invention are readily adaptable to a wide range of other pedal-actuated anti-embolic devices without departing from the scope and spirit of the invention.
