Description

A Multifunctional Bed

FIELD OF THE INVENTION

The invention relates to medical and therapeutic equipment, in particular, to medical beds, and may be used in in-patient hospitals, health care institutions, homes for the elderly people, and all kinds of social institutions; and also in homes for the caring of severely invalidated patients with limited mobility or complete immobility; for the caring of bed-ridden patients during the after-surgery period; and for the treatment of temporarily immobilized patients.

STATE OF THE ART

As is known, the design of a medical bed should provide to the nursing personal and relatives the possibility of a high-quality care of the patient; the patient should be in a comfortable and physiologically justified position.

One of the problems in servicing bed-ridden patients with severe health conditions is the presence of a constant loading on one or another body part, continuous horizontal position of the patient, which eventually results in a variety of congestive conditions in the pulmonary system and circulation system, and the occurrence of bed sores and congestive conditions in the patient's body organs and systems.

There are a great many models of medical beds addressing that problem that are designed to move and change the patient's body position to a greater or lesser extent.

Thus, a functional hospital bed is known wherein the upper platform is made of several sections for the purpose of changing and maintaining the intended patient position. The upper platform position and section tilt angles are managed with the help of a variety of driving mechanisms, e.g. manual or electric power-driven actuators (SU 1579505).

The bed design providing the possibility of continuously changing the position of the body and extremities of the patient is used to treat patients and casualties with severe combined injuries requiring round-the-clock therapeutic procedures preventing the occurrence of bed sores, atony and muscle atrophy, and improving cardiovascular functions and microcirculation in the patient.

For example, a medical bed is known that comprises a frame on wheels with brakes, end backrests, and an upper platform made of movable sections with pneumatic mechanisms for their raising and lowering containing air reservoirs and a compressed air source (RU 2231348). A medical bed is known comprising a base with backrests, a rotating frame with an actuator, and an upper platform, ensuring the turning over of the patient and enabling the performance of skeletal or extremity extension procedures on the patient (RU 1666108).

Medical beds are known which are designed to restore the function of the patient's vestibular system, prevent bed sores and extend the patient spinal cord under the load of the patient's own weight by the patient himself by means of lifting the patient into the vertical position (SU 1477406).

Such beds, comprising a base with wheels, an upper platform with pivotal ly connected breast, hip and leg sections, a mattress made of separate units, and an actuator in the form of two pivotal parallelograms, provide for the positioning of the patient in the lying-down, sitting and vertical positions (RU 2019165).

A medical verticalizer bed is known comprising a base with wheels, actuator, transmission with pulls, and upper platform stationed on the base, the said upper platform having the capability of being fixed at an angle to the base, and also the capability of being moved along the vertical plane and fixed in parallel to the base, which provides the possibility to carry out rehabilitation activities with the patient by means of putting the latter into vertical position (RU 2405520).

A medical bed is known comprising an upper platform with devices to fix the patient, legs, backrests, a base and a movable framework equipped with an actuator for rotation; wherein the base is made of an immovable outer framework on legs, with the said movable framework being affixed to the immovable outer framework by means of mobile connection devices, and with a movable inner framework being affixed to the said movable framework by means of mobile connection devices for the purpose of lifting the patient into vertical position, said movable inner framework being equipped with an upper platform, backrests and rotation actuator, with every bed actuator equipped with a worm gear and a handle, and wherein patient fixing devices are made of belts (RU 2186555).

All the above-listed bed designs are bulky and difficult to manage; they complicate patient care due to the lack of free access to the patient, require at least two people to service the patient, do not provide for the possibility of a combined patient movement in space, and arc designed to perform just one or a few functions. At the same time, more often than not significant physical efforts are required on the part of the paramedical personnel to handle and transport the patient, since hygienic treatment and rehabilitation procedures are performed in different locations. BRIEF STATEMENT OF THE INVENTION

The object of this invention is the creation of a multifunctional bed simple in design and management, which would enable, be means of a free combined change of the patient's position in the three-dimensional space along all the three axes, the selection of the most comfortable position of the patient, lowering of the labor intensity of care, and thus to significantly facilitate the care of severely ill and bed-ridden patients. At the same time, the bed may also be used for a variety of rehabilitation regimes and transportation of all kinds of patients, including bed-ridden and severely ill patients, wounded and damaged casualties, and also patients in the recuperation period.

Thus, the invention provides an opportunity to simplify the design of a hospital bed (at the same time broadening the functionality thereof), to increase the convenience of and generally facilitate patient care, and increase comfort both for the patient and care personnel.

A multifunctional bed is being proposed, comprising a base support with vertical guides affixed to the crosswise ends thereof and bed backrests installed on the said crosswise ends with the capability of being moved; a framework fastened to the bed backrests with the capability of being rotated with relation to the bed longitudinal axis and made of cross pieces connected with each other by means of longitudinal and transverse strips; an upper platform installed inside the frame with a capability of being turned, rotated and lifted in the vertical direction relative to the frame cross axis; wherein the upper platform consists of individual sections one of which is stationary relative to the frame, and the others are mounted with the capability of being rotated, wherein the frame is connected to the bed backrests, and the upper platform is connected to the frame, pivotally.

In preferable embodiments of the proposed multifunctional bed, the base support may be in the form of a knockdown structure and mounted on wheels; the cross pieces of the bed frame may be implemented in the form of semi-rims so as to make possible the manual rotation of the bed frame; the bed may be equipped with a coaxial guide mounted on the base support with a rack inside rigidly connected with the bed backrests and a paired actuator to rotate the bed upper platform relative to the frame, and rotate the upper platform sections. At the same time, the bed may be equipped with fixing devices for affixing the patient installed on the both sides of the upper platform, the latter being in turn equipped with removable frame structures with replaceable mattresses, wherein such removable frame structures are equipped with arrangements for sanitary and hygienic treatment or the performance of bodily functions.

The claimed bed is schematically shown in the drawings, where Fig. l shows a general lateral view; Fig.2 - view A on the bed end from the frame rotation actuator side; Fig.3 - a general view of the bed from above, view B; Fig. 4 - view C of Fig. 3; Fig. 5, 6 and 7 - the bed with a vertical position of the frame and vertical position of the upper platform, the bed with a vertical position of the frame and upper platform askew in relation to the frame, and the bed with a horizontal position of the frame and vertical position of the upper platform, respectively. Fig. 8. 9, 10 and 1 1 show different designs of replaceable mattresses, and Fig. 12 shows an isometric view of the bed.

The multifunctional bed comprises knockdown base support 1, in preferable embodiments mounted on wheels 2, with vertical guides 3 rigidly affixed to the crosswise ends thereof, ensuring the capability of bed backrests 4 and 5 to be moved coaxially along the said guides. The bed has frame 6 installed with the capability of being rotated around the longitudinal axis of the bed, said frame consisting of two cross pieces 7 and 8, implemented in the preferable embodiment in the form of semi-rims connected with each other by means of longitudinal strips 9 and 10 and transverse strips 1 1 and 12. Frame 6 is equipped with upper platform 13 installed inside frame 6 with the capability of being turned, rotated and lifted in the vertical direction relative to the frame 6 cross axis. For these purposes, upper platform 13 and frame 6 are pivotally connected with each other.

Upper platform 13 is implemented of several individual sections 14, 15, 16 and 17, with one installed stationary in relation to the upper platform, and the other with the capability of being rotated for the patient's convenience, enabling him to change of the position of the body along upper platform 13, let the legs down, or take a sitting position. The turn of the sections may be accomplished by means of paired actuator 18.

The bed is equipped with actuator 19, which is located on backrest 4 of the bed and connected with frame 6 and pivots 20 and 21, wherein pivot 20 is installed in backrest 4, and spherical pivot 21 is installed in frame 6 connected with backrest 5 by means of arm 22.

With the help of actuator 19, it is possible to rotate frame 6 of the bed and position upper platform 13 vertically or transversally relative to the bed.

The lifting mechanism of backrests 4 and 5 includes coaxial guides 23. racks 24 installed in the guides with the capability of being moved up and down, and actuator 25. Each section of upper platform 13 of the bed may be implemented (as shown in Fig. 8-9 and 10-1 1 ) in the form of removable framework structures 26 with replaceable mattresses 27. Framework structures 26 may be installed either with the help of longitudinal flanges 28 mounted in the profile grooves of upper platforma 13 (not shown on the drawing), or with the help of transverse flanges 29 with pins 30, mounted in the respective grooves and orifices of upper platform 13 (not shown on the drawing). Removable framework structures 26 are equipped with fixing devices 31 with soft cushings 32 to hold the patient in position. Paired drive 18 is connected with upper platform 13 and sections of the upper platform by means of two axles 33 and 34, and with frame 6 - by means of axle 35.

When caring to a severely ill patient, the bed may be used as follows:

Bed transportation is possible with the help of wheels 2. The change of rise of bed frame 6 is performed by moving backrests 4 and 5 along vertical guides 3 with the help of actuator 25. When actuator 25 is on, the lifting of the backrests is accomplished by moving racks 24 connected with backrests 4 and 5, inside coaxial guide 23 affixed on base support 1. It enables the paramedical personnel to conveniently perform the hygienic treatment of the patient without removing him from the bed; at the same time, labor intensity of care is reduced, which improves the quality of the caring to a severely ill bed-ridden patient. If necessary, the turn of bed frame 6 around the longitudinal axis may also be accomplished manually with the help of semi-rims 7 and 8 connected with frame 6 via longitudinal strips 9 and 10, which enables personnel to put the patient in the position necessary to improve microcirculation.

To perform a combined rotation of upper platform 13 along two perpendicular axes, rotation actuator 19 and paired actuator 18 are used. In that case, the torque is transmitted to the frame via a keyed or coupling connection to pivots 20 and 21, while paired actuator 18 installed at the side of upper platform 13 causes it to rotate with the help of axle 35. The split of upper platform 13 is performed with paired actuator 18 and axles 33 and 34. In so doing, both the separate turning of each individual section, or the joint turning of all the sections is possible, which ensures necessary comfort for the patient.

One of the many functions of the bed consists in the obtaining of the so-called verticalizer. For that purpose, frame 6 is turned by 90°, then upper platform 13 is turned relative to frame 6 by 80°, the position of upper platform 13 relative to frame 6 is fixed with the help of fixing devices (not shown on the drawing), and frame 6 is returned with the help of actuator 18 to the initial position. Frame 6 with the patient affixed to it will be at an angle of 90° to the horizontal plane. It ensures the restoration of functions of the patient vestibular system. prevention of bed sores or extension of the spinal cord under the patient own weight. Λ variety of angle combinations is possible, including a range of angles at which the upper platform is split up.

The bed may be managed both by hand or automatically, controlling the movements from the control device, which can be both portable or built in the bed backrest or e.g. the rails. The control device provides the possibility to program patient movements.

Thus, the claimed multifunctional bed allows, in contrast to the known ones, employing one person to perform care of a patient; care may be performed in one place without the need to exert physical efforts to relocate the patient; and the patient body may be approached from any side to any part of the body to perform all kinds of hygienic treatment or rehabilitation of the patient.
