Description
f BACKGROUND OF THE INVENTION
The present invention relates to therapeutic and pro-phylactic devices, and more particularly to devices for applying compressive pressures against a patient's limb.
It is known that the velocity of blood flow in a patient's extremities, particularly the legs, markedly decreases during confinement of the patient. Such pooling or stasis of blood is particularly pronounced during surgery, immediately after surgery, and when the patient has been confined to bed for extended periods of time. It is also known that stasis of blood is a significant cause leading to the formation of thrombi in the patient's extremities, which may have a severe deleterious effect on the patient, including death. Additionally, in cer-tain patient's it is desirable to move fluid out of interstitial spaces in extremity tissues, in order to reduce swelling asso-ciated with edema in the extremities.
Devices have been disclosed in U.S. patents 4,013,069 and 4,030,488 which develop and apply the desired compressive pressures against the patient's limbs. Such devices comprise a pair of sleeves which envelope the patient's limbs, and a con-troller for supplying fluid pressure to the sleeves through con-duits which are connected in fluid communication with chambers in the sleeve. However, it has been found that if undue forces are applied to the conduits during use, such as by movement o~
the patient's limbs, the conduits may become ruptured from the sleeve, thus causing fluid leakage in the device and rendering the sleeve useless.
SUMMARY OF THE INVENTION
A principal feature of the present invention is the provision of a device oE simplified construction for applying compressive pressures against a patient's limb.
The device of the present invention comprises, an elongated pressure sleeve for enclosing a length of the patient's limb, with the sleeve having a pair of flexible sheets of fluid impervious material having a pair of side edges, and a pair of end edges connecting the side edges. The sleeve has means for connecting the sheets together along lines defining a plurality of separate laterally extending inflatable chambers disposed longitudinally along the sleeve, and defining a pair of opposed flaps adjacent one of the side edges extending longitudinally along the sleeve, with a flap of one of the sheets having a plurality of openings spaced longitudinally along the flap of the one sheet. The device has a plurality of conduits, and a plurality of connectors secured to the one sheet and connecting the conduits in fluid communication with the chambers. The con-duits extend from the connectors through the flap openings of the one sheet and between the flaps toward one end edge of the sheet.
A feature of the present invention is that the flap openings and flaps retain the conduits at a desired position relative to the sleeve.
Another feature of the present invention is that the flaps confine the conduits in a compact configuration along a side of the sleeve.
Still another feature of the invention is that the flaps prevent the conduits from falling into disarray.
~et another feature of the invention is the provision of means for securing the flaps to -the conduits adjacent one end edge of the sheets.
7~
Thus, a featuxe of the presenk invention i5 that the flaps relieve possible stra,in from the connectors in the event that forces are applied to the conduits exterior the sheets.
Accordingly, anothex feature of the invention is that S the flaps minimize the possibility that the connectors may become severed from the sleeve during use of the device.
Further features will become more fully apparent in the following de'scription of the embodiments of this invention and from the appended claims.

7~i!i~1Ei DESCRIPTION OF THE PREFERRED EMBODIMENTS
. . _ .
Referring now ~o Fig~ 1, there is shown an intermittent compression device generally designated 20 having a controller 22, and a pair of elongated compression sleeves 26 for enclosing a length of the patient' s extremities, such as the legs as shown.
The controller 22 is connected throu~h a tube 28 to a source S
of pressurized gas, and to an e~aust tube 30. Also, the c:on-txoller 22 is connected to the separate sleeves 26 ~hrough sepa-rate sets of conduits 34 and 35. The controller may be of any suitable type, such as the controllers described in U.S. patents 4,013,069 and 4,030,~88.
With reference to Figs. 2 and 3, the sleeve 26 has an outer cover sheet 36 covering the entire outer surface of an outer fluid impervious barrier sheet 38. Also, the sleeve 26 lS has an inner cover sheet 40 covering an inner surface of an inner fluid impervious barrier sheet 42. The outer cover sheet 36 may comprise a relatively inelastic fabric with a brushed matte or napped finish of nylon or polyester, such as a fabric sold under the trademark Flannel/Flannel II, No. 11630, by Guilford Mills, Greensboro, North Carolina, which provides an attractive outer surface for the sleeve, and also defines brushed or napped fibers across the entire outer surface of the sleeve for a purpose whi~h will be described below. In sui$able form, the fabric of the sheet 36 may be warp knit from polyester yarns on a tricot machine, after which tha fabric is dyed to a suitable color, and the fab-ric is brushed or napped on a suitable machine to raise loops from the fabric. The inner cover sheet 40 may comprise a sui~able nonwoven material which provides a comforta~le inner ~urface of the sleeve for the patient. The barrier sheets mRy be formed from a suitable flexible plastic material, such as polyvinylchloride.
8~
If desired, a segment of the bru~hed nylon fabric may be fo~med into a tube 44 to cover the conduits which extend from the sleeve to the controller. As shown, the conduits and cov~ring tube 44 may extend through an opening 46 in the inner cover sheet 40.
s The sleeve 26 may have a pair of ~ide edges 48a and 48b, and a pair of end edges 50a and 50b connecting the side edges 48a and b, with the side edges 48a and b being tapered toward a lower end of the sleeve. The sleeve 26 may also have an elongated opening 52 extending through a knee region 53 of the sleeve, and defined by peripheral edges 54 extending around the opening 52. In addition, the sleeve 26 has an elongated opening or cut-out 56 in the knee region 53 extending from the side edge 48a toward a lateral central portion of the sleeve, with the opening 56 being defined by peripheral edges 58 extend-ing from the side edge 48a around the opening 56. As shown, theinner end of the opening 56 is spaced from the opening 54, and the opening 56 defines an upper flap 60 and a lower flap 62 of the sleeve which are separated by the opening 56. Further, the sleeve 26 may have a pair of lower fastening strips 61~ suc~ as a hook material sold under the trademark Velcro, secured to ~he inner cover sheet 40 along the side edge 48b.
With reference to Figs. 4-8, the inner and outer fluid impervious barrier sheets 38 and 42 have a plurality of later-ally extending lines 64, such as lines of sealing, connecting the barrier sheets 38 and 42 together, and longitudinally extend-ing lines 66, such as lines of sealing, connecting the sheets 38 and 42 together and connecting ends of the lateral lines 64, as shown. The connecting lines 64 and 66 define a plurality of longitudinally disposed chambers 68a, 68b, 68c, 68d, 68e~ and 68f, which for convenience will be termed cvntiguous. As shown, the chambers 48 extend laterally in the sheets 38 and 42, and are dis-posed in the longitudinal arrangement between the end edges 50a and 50b. When the sleeve is placed on the patient's leg, the ~ lowermost chamber 68a is located on a lower paxt of the leg adja-cent the patient's ankle, while the uppermost chamber 68f is located on an upper part of the leg adjacent the midthigh.
As shown, the longitudinal line 66 nearest the side edge 48b is separated intermediate the chambers 68b and c, 68c and d, and the chambers 68e and f. The lateral lines 64 define ventilation channels 70a, 70b, and 70c extending laterally in the sleeve from the longitudinal line 66 adjacent the side edge 48a toward the longituainal li~es 66 adjacent the side edge 48b, with the ventilation channels 70 being positioned at spaced locations longitudinally along the sleeve intermediate different pairs of adjoining chambers. Thus, the ventilation channel 7~a is located intermediate the chambers 68b and 68c, the ventilation channel 70b is located intermediate the chambers 68c and 68d, and the ventilation channel 70c is located intermediate the chambers 68e and 68f. Moreover, the ventilation channels 70 have a width su~stantially less than the width of the chambers 68 such that the channels 70 do not detract from the size and volume required for the compression chambers 68. The inner and outer barrier sheets 38 and 42 also have a longitudinally extending line 72 which defines a connecting channel 74 intermediate the Iine 72 and the adjacent longitudinal line 66. As shown, the connecting channel 74 extends along the sides of the chambers 63c, 68d, and 68e, and communicates with the ventilation channels 70a, b, and c, such that the channel 74 connects the spaced ventilation chan-nels 70. Further, the inner barrier sheet 42 has a pluxality of openings or apertures 76 which communicate with the channels 7~.
7~a~
Thus, when the sleeve ~6 is placed on the pat3ent's leg, the open-ings 76 face toward the leg.
With refexence to Figs. 4-7, the longitudinal lines 66 and 72 adjacent the side edge 48b define a pair c~f flaps 78a and 5 78b of the barrier sheets 38 and g2 which ex~end between the respective lines and the side edge 48b. As shown, the sheets 38 and 42 have a longitudinally exterlding line 79 which defines a directing channel 80 intermediate the lines 79 and 72 9 wit:h the opposed longitudinal ends of the channel 80 being open~ The 10 sleeve 26 has a first connecter 82a which is conuoonly connected in fluid comsnunication to the two lowermost cham~ers 68a and 68b, and which is connected to a conduit 34a in the illustrated con-duit set 34. As shown, the conduit 34e passes through an opening 84a in the upper barrier sheet flap 7~a which retains the conduit 34a at the aesired position in the sleeve 26. The sleeve 26 also has a second connecter 82b which is commonly connected in fluid conununication to the second pair of adjoining chambers 68c and 68d, and which is connected to a second conduit 34b in the con-duit set 34. The conduit 34b passes through an opening 84b in the upper flap 78a which retains the conduit 34b at the desired position. The sleeve 26 has a third connecter 82c which is com-monly connected in fluid colT~nunication to the uppermost chaJllbers 68e and 68f, and which is connected to a third con~uit 34c in the conduit set 34. As shown, the conduit 34c passes through an opening 84c in the upper flap 78a, with the conduit 34c extend-ing through the directing channel 80 in order to retain th~ third conduit 34c at the desired position in the sleeve. The ~;leeve 26 also has a fourth connecter 82d whic:h is connected in fluid con~nunication to the connecting channel 74 in order to permit 30 passage of air to the ventiIation ~annels 70. A.s shown, the connecter 82d is connected to a fourth conduit 34d in the conduit set 34, with the conduit 34d passing through an opening 84d in the upper barrier flap 78a. Thus, the conduits 34a, 34b, and 34c are separately connected to pairs of adjoining chambers, while the conduit 34d is connected to the connecting channel 74. Of course, the other sleeve associated with the conduits 35 may be constructed in a similar manner. It will be apparent that the barrier flaps 78a and 78b, the directing channel 80, and the openings 84 cooperate to retain the conduits at the desired posi-tion within the sleeve. Further, the sleeve 26 has suitablesecuring means 86, such as regions of heat sealing or adhesive, bonding the flaps 78a and 78b to opposed sides of the conduits 34 adjacent the opening 46. Thus, in the event that forces are applied to the conduits 34 exterior the sleeve 26, the forces are transmitted to the flaps 78a and b rather than the connectors 82a, b, and c, in order to relieve possible strain from the con-nectors and prevent severance of the connectors from the sleeve.
In use, the sleeve 26 may be placed below the patient's leg preparatory to securement about the limb, as illustrated in Fig~ 9. Next, the upper flap 60 and lower flap 62 may be inde-pendently passed around the patient's leg at locations above and below the knee, respectively. Thus, the opening 56 separates the flap portions of the sleeve in the region of the knee to per-mit independent wrapping of the upper and lower portions of the sleeve about the leg and simplify placement of the sleeve, as well as provide an improved fit. After both the upper and lower flaps 60 and 62 have been suitably wrapped about the patient's limb, the remaining part of the sleeve adjacent the s.ide edge 48b may be wrapped over the flaps 60 ana 62, and the fastening strips 61 may be pressed against the outer cover sheet 36. Thus, the hook fastening strips 61 engage with the brushed fibers of the outer cover sheet 36, such ~hat the strips 61 and sheet 36 inter-engage and retain the sleeve in the wrapped configuration.
Since the sheet 36 extends entirely across the outer surface of the sleeve 26, the sleeve may be readily adjusted as necessary for the desired fit according to the size of the patient's leg.
Thus, the sleeve 26 may be placed in a simplified manner while accomplishing an improved fit on patients having varying leg sizes. In addition, the openings 52 and 56 greatly reduce the amount of material and bulk for the sleeve in the region of the patient's knee, Accordingly, the sleeve provides flexibility in the knee region in order to prevent binding and permut flexation of the knee during the extended periods of time while the sleeve is secured about the leg.
After placement of the sleeves on the patient's limbs, the controller 22 may be initiated in order to supply air to the sleeves 26. The controller 22 intermittently inflates the cham-bers 68 during periodic compression cycles, and intermittently deflates the chambers 68 through the exhaust tube 30 during periodic decompression cycles intermediate the compression cycles.
The inelastic cover sheet 36 of the placed sleeve restricts the size of the inflated chambers, and greatly enhances the compres-sive action of the chambers to permit lower fluid volumes dur-ing the compression cycles. Further, the ~ontroller 22 supplies air through the conduits to the connecting channels 74 in the two sleeves. The air then passes from ~he common connecting channels 74 to the spaced ventilation channels 70 and through the openings 76 onto the patient's legs. In this manner, the device 20 ventilates a substantial portion of the patient's legs to prevent heat buildup and pxovide comfort for the patient dur-ing extended periods of time while the sleeves are retained in a wrapped condition about the patient's limbs. In a preferred form, the controller 22 supplies air to the ventilation channels 70 during the periodic decompression cycles. Also, the con-troller 2~ may have suitable means, such as a switch, to selec-tively permit passage of air to the ventilation channels 70 or prevent passage of air to ~he ventilation channels 70, as desired.
In aadition, the switch may be utilized to control the quantity of air which ventilates the patient's limbs for maximum patient comfort.
The foregoing detailed description is given for clear-ness of understanding only, and no unnecessary limitations should be understood therefrom, as nodifications will be obvious to those skilled in the art~
The present invention relates to therapeutic and pro-phylactic devices, and more particularly to devices for applying compressive pressures against a patient's limb.

As shown, the chambers 48 extend laterally in the sheets 38 and 42, and are dis-posed in the longitudinal arrangement between the end edges 50a and 50b. When the sleeve is placed on the patient's leg, the ~ lowermost chamber 68a is located on a lower paxt of the leg adja-cent the patient's ankle, while the uppermost chamber 68f is located on an upper part of the leg adjacent the midthigh.
As shown, the longitudinal line 66 nearest the side edge 48b is separated intermediate the chambers 68b and c, 68c and d, and the chambers 68e and f. The lateral lines 64 define ventilation channels 70a, 70b, and 70c extending laterally in the sleeve from the longitudinal line 66 adjacent the side edge 48a toward the longituainal li~es 66 adjacent the side edge 48b, with the ventilation channels 70 being positioned at spaced locations longitudinally along the sleeve intermediate different pairs of adjoining chambers. Thus, the ventilation channel 7~a is located intermediate the chambers 68b and 68c, the ventilation channel 70b is located intermediate the chambers 68c and 68d, and the ventilation channel 70c is located intermediate the chambers 68e and 68f. Moreover, the ventilation channels 70 have a width su~stantially less than the width of the chambers 68 such that the channels 70 do not detract from the size and volume required for the compression chambers 68. The inner and outer barrier sheets 38 and 42 also have a longitudinally extending line 72 which defines a connecting channel 74 intermediate the Iine 72 and the adjacent longitudinal line 66. As shown, the connecting channel 74 extends along the sides of the chambers 63c, 68d, and 68e, and communicates with the ventilation channels 70a, b, and c, such that the channel 74 connects the spaced ventilation chan-nels 70. Further, the inner barrier sheet 42 has a pluxality of openings or apertures 76 which communicate with the channels 7~.
7~a~
Thus, when the sleeve ~6 is placed on the pat3ent's leg, the open-ings 76 face toward the leg.
With refexence to Figs. 4-7, the longitudinal lines 66 and 72 adjacent the side edge 48b define a pair c~f flaps 78a and 5 78b of the barrier sheets 38 and g2 which ex~end between the respective lines and the side edge 48b. As shown, the sheets 38 and 42 have a longitudinally exterlding line 79 which defines a directing channel 80 intermediate the lines 79 and 72 9 wit:h the opposed longitudinal ends of the channel 80 being open~ The 10 sleeve 26 has a first connecter 82a which is conuoonly connected in fluid comsnunication to the two lowermost cham~ers 68a and 68b, and which is connected to a conduit 34a in the illustrated con-duit set 34. As shown, the conduit 34e passes through an opening 84a in the upper barrier sheet flap 7~a which retains the conduit 34a at the aesired position in the sleeve 26. The sleeve 26 also has a second connecter 82b which is commonly connected in fluid conununication to the second pair of adjoining chambers 68c and 68d, and which is connected to a second conduit 34b in the con-duit set 34. The conduit 34b passes through an opening 84b in the upper flap 78a which retains the conduit 34b at the desired position. The sleeve 26 has a third connecter 82c which is com-monly connected in fluid colT~nunication to the uppermost chaJllbers 68e and 68f, and which is connected to a third con~uit 34c in the conduit set 34. As shown, the conduit 34c passes through an opening 84c in the upper flap 78a, with the conduit 34c extend-ing through the directing channel 80 in order to retain th~ third conduit 34c at the desired position in the sleeve. The ~;leeve 26 also has a fourth connecter 82d whic:h is connected in fluid con~nunication to the connecting channel 74 in order to permit 30 passage of air to the ventiIation ~annels 70. A.s shown, the connecter 82d is connected to a fourth conduit 34d in the conduit set 34, with the conduit 34d passing through an opening 84d in the upper barrier flap 78a. Thus, the conduits 34a, 34b, and 34c are separately connected to pairs of adjoining chambers, while the conduit 34d is connected to the connecting channel 74. Of course, the other sleeve associated with the conduits 35 may be constructed in a similar manner. It will be apparent that the barrier flaps 78a and 78b, the directing channel 80, and the openings 84 cooperate to retain the conduits at the desired posi-tion within the sleeve. Further, the sleeve 26 has suitablesecuring means 86, such as regions of heat sealing or adhesive, bonding the flaps 78a and 78b to opposed sides of the conduits 34 adjacent the opening 46. Thus, in the event that forces are applied to the conduits 34 exterior the sleeve 26, the forces are transmitted to the flaps 78a and b rather than the connectors 82a, b, and c, in order to relieve possible strain from the con-nectors and prevent severance of the connectors from the sleeve.
In use, the sleeve 26 may be placed below the patient's leg preparatory to securement about the limb, as illustrated in Fig~ 9. Next, the upper flap 60 and lower flap 62 may be inde-pendently passed around the patient's leg at locations above and below the knee, respectively. Thus, the opening 56 separates the flap portions of the sleeve in the region of the knee to per-mit independent wrapping of the upper and lower portions of the sleeve about the leg and simplify placement of the sleeve, as well as provide an improved fit. After both the upper and lower flaps 60 and 62 have been suitably wrapped about the patient's limb, the remaining part of the sleeve adjacent the s.ide edge 48b may be wrapped over the flaps 60 ana 62, and the fastening strips 61 may be pressed against the outer cover sheet 36. Thus, the hook fastening strips 61 engage with the brushed fibers of the outer cover sheet 36, such ~hat the strips 61 and sheet 36 inter-engage and retain the sleeve in the wrapped configuration.
Since the sheet 36 extends entirely across the outer surface of the sleeve 26, the sleeve may be readily adjusted as necessary for the desired fit according to the size of the patient's leg.
Thus, the sleeve 26 may be placed in a simplified manner while accomplishing an improved fit on patients having varying leg sizes. In addition, the openings 52 and 56 greatly reduce the amount of material and bulk for the sleeve in the region of the patient's knee, Accordingly, the sleeve provides flexibility in the knee region in order to prevent binding and permut flexation of the knee during the extended periods of time while the sleeve is secured about the leg.
After placement of the sleeves on the patient's limbs, the controller 22 may be initiated in order to supply air to the sleeves 26. The controller 22 intermittently inflates the cham-bers 68 during periodic compression cycles, and intermittently deflates the chambers 68 through the exhaust tube 30 during periodic decompression cycles intermediate the compression cycles.
The inelastic cover sheet 36 of the placed sleeve restricts the size of the inflated chambers, and greatly enhances the compres-sive action of the chambers to permit lower fluid volumes dur-ing the compression cycles. Further, the ~ontroller 22 supplies air through the conduits to the connecting channels 74 in the two sleeves. The air then passes from ~he common connecting channels 74 to the spaced ventilation channels 70 and through the openings 76 onto the patient's legs. In this manner, the device 20 ventilates a substantial portion of the patient's legs to prevent heat buildup and pxovide comfort for the patient dur-ing extended periods of time while the sleeves are retained in a wrapped condition about the patient's limbs. In a preferred form, the controller 22 supplies air to the ventilation channels 70 during the periodic decompression cycles. Also, the con-troller 2~ may have suitable means, such as a switch, to selec-tively permit passage of air to the ventilation channels 70 or prevent passage of air to ~he ventilation channels 70, as desired.
In aadition, the switch may be utilized to control the quantity of air which ventilates the patient's limbs for maximum patient comfort.
The foregoing detailed description is given for clear-ness of understanding only, and no unnecessary limitations should be understood therefrom, as nodifications will be obvious to those skilled in the art~
