Abstract

Rehabilitative walker is designed to perform physical exercises helping to recover the lost or nurture the lacking abilities to walk, keep the balance, or other similar abilities. The walker is new due to the fact that the patient is suspended in the walker so that there is not a single suspension point but two suspension points and they are moved into walker's sides and supported by pneumatic cylinders with the ability to control the air supply to the cylinders, allow a suspension to replicate the patient's hip movements with higher precision, facilitate or exacerbate waddling of the patient's hips, such an arrangement enables to measure load on the legs and keep track of the suitability of the procedures to the patient during rehabilitation with sufficient accuracy. The walker accurately simulates and effectively stimulates natural movements of the human when walking. The suspension mechanism is attached to the walker through the ball joint connection, due which the patient can not only freely waddle from side to side but also rotate around a vertical axis. The suspension mechanism has removable handholds. Back support is attached in a way that when determining the correct angle of inclination of the patient's back at the same time remains tight-fitting to the patient's back and does not restrict his movements. Method of attachment of metal leg joints enables the legs to not respond to the patient's waddle at the waist from side to side. The new method of attachment of the stable handhold enables one person quickly and easily immovably attach the stable handhold to the walker frame or remove it.

Description

TECHNICAL FIELD

TECHNICAL FIELD OF THE INVENTION Rehabilitation equipment, and more specifically, rehabilitation walkers for the development of lost or lacking ability to walk, walk, balance, and the like.

TECHNICAL LEVEL

US6733018B2 (published May 11, 2004) discloses a walker with the patient attachment device facing the patient. This document provides two pneumocylinders for lifting the patient, but there is no possibility of leaning on the elbows, nor is it possible to attach a leg motion synchronization device. The only means of anchoring the patient in the walker is a suspended soft saddle, but it is too loose, uncontrolled, which makes it difficult to properly anchor the patient, and there is no possibility of choosing a tilt angle. The patient's lifting arm is located between the arm and the body, which may interfere with the operation of the arm, comfortable grip on the walker, and general discomfort when using the walker.

The application VVO201414575789 (published 18/09/2014) provides a walker in which the patient is secured with straps that are fastened over the patient, which may cause the patient to start rocking. As the patient steps in, due to the long straps, the walker may begin to lag behind the patient, which may annoy the patient. Also, it is not possible to accurately determine the back inclination angle. In addition, the walker places the patient well above the human center of gravity, which severely limits the patient's center of gravity recruitment and does not train the back muscles, resulting in less effective rehabilitation.

The closest analogue to the state of the art is patent application VV02014001853A1 (published 03.01.2014), which describes a rehabilitation walker. The rehabilitation walker described has a frame-base with casters that rest on the floor or other horizontal surface. Other elements forming the walker are attached to said frame: a knee and foot control mechanism; a stable arm resting on the patient's elbows, gripping the arms; lifting mechanism; suspension device and other. The frame described in this document, together with the attached knee and foot control, resembles a hollow rectangle where the wheels are mounted near the corners of the rectangle. With the knee and foot control removed, the walker can reach the patient chair with its own frame. Once the patient is stuck in the walker, it is difficult to remove the chair because the walker is obstructed on three sides and the patient on the fourth side, which makes it very difficult to remove and prepare for exercises with the patient. In the event that the patient becomes unconscious during the procedure on the walker, it is very difficult to remove the patient from the walker. Removable handle for patient support and grip, fixed to the frame of the walker. After removing the handpiece, the patient no longer has any arm support. Often, arm support is required to grip and hold body posture, but the presence of a stable, fixed handle at certain stages of patient healing no longer promotes progress, as the handle can be firmly gripped, which would greatly benefit from a flexible, unstable grip. The walker lift mechanism described in this application has a pneumatic cylinder for lifting, lowering the patient and also acts as a cushioning device. The said pneumatic cylinder, together with the lifting mechanism, holds the suspension mechanism. The lifting mechanism used in the walker described above consists of: one vertical mechanism and one pneumatic cylinder, which causes the attachment of the attachment to a single point about which the attachment may oscillate. In this way, the patient can move the weight from one foot to the other at said anchorage, since it is necessary to move the weight through that anchorage. The weaker the patient, the more this discomfort becomes manifest, the less effective the rehabilitation is.) In the walker described, the suspension mechanism can rotate about horizontal axes, i.e. the patient, together with the suspension mechanism attached to the torso area, can swing to the sides and may lean forward, backward but cannot rotate about its vertical axis. The angle of the backrest can only be changed before the procedure or after removing the patient from the walker. This is very inconvenient as it is almost impossible to determine in advance the right angle for the patient's back.

THE SUBSTANCE OF THE INVENTION

The present invention provides a rehabilitation walker for exercise that aids in regaining lost or untrained walking, balance, or other similar purpose.

Provides a rehabilitation walker with: frame (4), connecting member (2), ball joints (3), two pneumatic cylinders (1), flexible (5), patient backrest angle adjustment mechanism (9), patient suspension arm mechanism (I), stable handle (7), foot control (10), pneumatic control panel (16), fasteners and other elements.

The walker is new because the patient is hung in the walker without a single point of attachment, two points of attachment are carried to the sides of the walker, supported by pneumatic cylinders with air-to-cylinder control, more accurate patient hip movement, easier or more difficult to measure the load on the leg with sufficient accuracy and to monitor the suitability of the procedures performed during the patient's rehabilitation. The suspension mechanism is attached to the walker via ball joints, which allows the patient not only to move sideways freely, but also to pivot about a vertical axis. The backrest is designed so that the patient's back tilt angle can be adjusted and adjusted during the procedure, while the backrest remains snug and replicates the patient's walking direction without limiting his or her movements. The new design features more comfortable, ergonomic layout details, i.e. a connecting element (2) and a handle (6), which allow the accompanying person (physiotherapist) to adjust the gait, assist in guiding and pulling the walker during the procedure from the side or from the front of the walkers. The method of attaching the metal leg hinges allows the feet to not react to the patient's lateral movement through the torso. The new method of mounting a stable handle allows one person to quickly or easily attach or remove a stable handle to the walker frame.

The walker described is much more accurate than analog walkers, imitating normal human movements while walking, does not restrict the patient's freedom of movement, and effectively contributes to patient rehabilitation.

PREFERRED EMBODIMENTS

The Rehabilitation Walker is designed for exercise that will help restore the ability of patients who have partial control of their legs, who are no longer in balance, or who have other problems with their feet. The patient is anchored to the walker from a sitting (or standing or lying) position, with a brace and ligaments hugging the patient across the torso and thighs; lifted to the required height to properly load the legs while also providing stability. A foot control can be used for additional leg stimulation. The walker maintains the patient's upright position and adjusts the foot load. Once a walker is embedded, the patient can begin to practice the necessary steps to help restore walking.

This description uses the X, Y, and Z axes for a more comfortable positioning of objects in 3D. The X-axis is parallel to the horizontal base on which the walker is applied, the X-axis being along the walker, i.e. the patient entrenched in the walker going straight in the X-axis directions. The Y axis is parallel to the horizontal base on which the walker is used, the Y axis perpendicular to the X axis. The Z axis is perpendicular to the horizontal base on which the walker is used, and the Z axis is perpendicular to each of the X and Y axes mentioned.

The rehabilitation walker included in this description has at least the following components:

a frame (4) comprising wheels and an arch-shaped member;

a connecting member (2) comprising a horizontal elongated member and an elongate holding member;

ball joints (hereinafter referred to as "ball joints") (3), two pneumatic cylinders (1) comprising pistons and air flow openings; a flexible (5), patient back support angle adjustment mechanism (hereinafter referred to as an angle adjustment mechanism) (9) comprising a handle, an outer member, an inner member, and mounting axes;

a patient suspension mechanism with a handle (I) comprising a metal leg bracket attachment, soft part brackets, and a retaining assembly;

a stable handle (7);

a foot control mechanism (10);

a pneumatic control panel (16) comprising control arms, a panel and valves for regulating air flow;

fasteners and other supporting elements.

The walking frame (4) (Fig. 1, Fig. 2) rests on the horizontal base with the wheels attached to it. The casters are mounted so as to rotate about the axis of attachment of the casting member, i.e. the walker can change the direction of movement both front and rear. The casters also have the ability to lock the pivoting attachment axis of the wheel attachment. The walker can then roll back and forth without turning. Each caster has a brake which can be activated if necessary to prevent the caster from rotating, i.e. the walker would not travel. Casters in the description can be referred to as front (they are directed in the direction of the walker forward) and rear - as the walker moves forward, they follow the front wheels.

The frame (4) is made of an elongate metal element, a rod, a tube by bending or bending it by using several elongated elements, joined by additional connecting elements. An elongated member extends from the attachment point of one of the front wheels towards the rear wheels, and there is a mounting mechanism (8) for a stable handle (7) near the attachment point of the front wheel; extending towards the rear wheels, there is an attachment unit for the pneumatic cylinder (1), behind which the frame (4) is inclined upwards, together with the rear wheel mounted to the point of inclination, the frame (4) rises to a height such that the chair or other object from which the patient is raised; the frame (4) being inclined to the desired height is inclined to the opposite side of the walker, where approximately a central horizontal portion of the frame (4) (upper part of the arch of the frame (4)) is fitted with an angle adjusting mechanism (9). The frame (4) extending further from the angle setting mechanism (9) to the other side reproduces the bends and shapes already described on one side. In another embodiment, a further elongated member is mounted near the rear wheel, having a shape similar to a portion of the frame (4) extending from one rear wheel to the other rear wheel. Another elongated element is required to ensure the rigidity and rigidity of the walker frame. Each elongated bent element next to each other in its shape resembles an arch. One of these elements (4) of the frame (4) extending from one end wheel to the other end wheel is attached to its angle setting mechanism (9). Another elongated element of the arch-shaped frame (4) is fixedly attached to the horizontal elongated element of the connecting element (2), which is fixedly fixed to said angle setting mechanism (9). The shape of the frame (4) is symmetrical with respect to the plane containing the X and Z axes located in the middle of the walker, i.e. the shape of the frame (4) on one side of said plane mimics the shape on the other side of said plane.

The two elongated elements of the arch-shaped frame (4) allow the walker to pass over the base (eg chair, lying object, etc.) on which the patient is standing. The said base, on which the patient sits or rests, passes below the two elongated elements of the arch-shaped frame (4) as the walker moves, passing through the inner part of the arch.

Angle adjustment mechanism (9). Attached to said two elongated elements of the arch-shaped frame (4) is an angle adjusting mechanism (9). As described, one of the elements of the arch-shaped frame (4) can be attached to the connecting element (2) itself, which is attached to the angle setting mechanism (9). The angle setting mechanism (9) itself resembles a rectangular parallelepiped without a single large wall; its cross-section resembles a rectangle without one long edge. One of the elongated members of the arch-shaped frame (4) is attached to the existing longitudinal wall of the cross-section, and there is a hole in the long edge through which the handle for adjusting the backrest angle is slit. The boundary walls adjacent to the said longitudinal border have holes which pass through the axis in the direction of the Y axis. The described part of the angle setting mechanism (9) forms an outer element of the whole mechanism (9), to which the frame (4), the connecting element (2) are fastened, and the said axis accommodates a similarly shaped but smaller inner element which fits easily in the outer element. , not touching the side walls of the outer member. The inner member of the angle setting mechanism (9) is secured to the outer by an axis which is passed through said openings in the outer member, through the holes in the inner member, as well as through the fastening member of one of the hinges (5). Another hinge (5) is attached to the lower element of the inner angle adjustment mechanism (4).

The directional projection of the hinges (5) (Fig. 4) in the horizontal plane coincides with or close to the X-axis. The hinges (5) are fastened to each other by means of their ends, which allow a plurality of hinges (5) interlocked at one point to pass axes or pins perpendicular to the direction of the hinges (5) so that the hinges (5) . The hinge system (5) comprises at least 5 hinges (5) and their fasteners 7 an inner member of the angle setting mechanism (9) and a back support (11). In this way, all at least 7 elements are connected so as to form at least two parallel sides connected by one edge. The handle of the angle setting mechanism (9) is mounted in the lower part of the angle setting mechanism (9) so that it can rotate about its longitudinal axis, while rotating the handle changes the distance between the inner and outer parts of the angle setting mechanism (9). The axis at the top of the angle setting mechanism (9) holds the entire flexible system (5). As the distance between the inner and outer edges of the elements of the angle setting mechanism (9) changes, the angle between the two interconnected hinges (5), i.e. between two adjacent sides of a parallelogram. By rotating the handle and thereby changing the angle of one of the edges of the parallelogram formed by the hinges (5) with respect to the Z axis, said change of angle is transmitted to the back support (11) via a system of two parallelograms.

The back support element (11) is part of the patient suspension mechanism (I) and is no different from the support element as described in the nearest analogue (VV02014001853A1). As described above, said system of hinges (5), which is attached to the back support element (11) via ball hinges, allows the back support element (11) to move together with the patient suspension mechanism (I), i.e. the backrest (11) always moves close to the patient's back, mimicking the patient's movements in direction, and always remains within a defined heeling angle, when in the nearest analog document the backrest was unable to direct and reproduce the patient's movements.

The angle setting mechanism (9) enables the patient to adjust the angle of inclination of the patient not only continuously, without steps, but also without removing the patient from the walker during the procedure.

The connecting element (2) connects the pedestrian frame (4) to the patient suspension mechanism (I), together with the pneumatic cylinders (1), holds the entire patient suspension mechanism (I). The length of the elongate member of the horizontal connector (2) is approximately equal to the average width of the human shoulders. As mentioned above, the horizontal elongated member of the connecting element (2) is fixed to its angle setting mechanism (9) through its center. The outer ends of the horizontal elongate member of the coupling member (2) terminate with sliding bearings on which the elongated holding members of the coupling member (2) are fixed at their ends, on which the patient suspension mechanism (I) is fixed at the other end. The bearings allow the elongated holding members to rotate easily about the longitudinal axis of the horizontal member. The pneumatic cylinder (1) is pivotally mounted to each elongated support member, closer to the end of the member to which the ball joint is attached, by means of its supporting members. The supporting elements of the connecting element (2) in the walker are mounted so that they protrude sufficiently to the sides of the walker. The parameters of the elongated horizontal and support members of the connector (2) and their position in the walker are such that the person caring for the patient in the walker can support the walker without hindrance, comfort and ergonomics, assisting the patient in rehabilitation exercises.

The connection of the components of the connecting element (2) with bearings enables the precise measurement of the force on which the patient rests on a stable base, the walker to react more accurately to the patient's movements, and the patient to adapt better to the patient's movements. If said components were to be joined by non-low friction elements (in this case bearings), it would be difficult to accurately measure said force due to the frictional force resulting from the connection of said components.

Ball joints (hereinafter referred to as "ball joints") (3). The connecting member (2) holds the patient's suspension mechanism (I) through the ball hinges (3). The ball hinge (3) comprises at least the following components: a ball head mounted on the end of the elongate retaining members of the coupling member (2), on which a sleeve at the end of the elongated ball hinge (3) element is inserted. At the other end of the elongated member of the ball hinge (3) is another sleeve which is fitted on the head and secured to the patient's suspension mechanism (I). The ball heads (3) of the ball hinge (3) can rotate about the longitudinal axis of the elongated ball hinge (3) element, as well as the elongated hinge (3) element can bend relative to the hub. With such ball hinges (3), the patient suspension mechanism (I) attached to the coupling (2) can move in all directions (i.e., rotate about each of the X, Y, Z axes) to the extent allowed by the properties of the ball hinge (3). The present invention uses a ball hinge (3) having an elongated hinge member of between 7 and 15 cm. length. Particularly important is the ability of the suspension mechanism (I) to rotate about the Z axis: this movement enables the patient to rotate the hip about the spinal axis in a step.

Patient suspension mechanism (I). The suspension mechanism (I) is analogous to the nearest analog described in document WO01414001853A1, except that it has easily removable handles (6). The shape of the handle (6) resembles an "L" shape, with the end of the long edge slightly inclined in a direction perpendicular to the plane containing the two edges forming the handle (6). This inclination is formed to make it more comfortable to grip the handle (6) so that the wrist of the slightly bent elbow remains as straight as possible. This inclination includes a portion of a rubber, plastic or similar material, a grip that can be gripped by the patient. The handle (6) is attached to the suspension mechanism (I) in two places. The short end of the handle (6) is hollow and the suspension mechanism (I) has a protrusion corresponding to the inner shape of the short end cavity. In this way, the short edge of the handle (6) is pressed against the said protrusion (I). The other attachment point for the handle (6) is realized on the long side of the handle (6), further away from the angle formed by the joined edges. The long sides of the transverse handrail (6) are the hole through which the screw (12) (Fig. 3) is inserted and screwed to the mounting mechanism. After screwing the screw (12) into the suspension mechanism (I), the bolt (12) presses the handle (6) against the suspension mechanism (I) with its head. Alternatively, the handle (6) may be attached to the suspension mechanism (I). Not only does the armrest (6) allow the patient to grip for a firmer feel, but also allows for additional manual control of the hip. The patient may tilt the hip joint with the hand by pushing the handle (6) downwards or upwards while walking and tilting. In this way, guiding during walking can be achieved by manually depressing or lifting the handle (6), which is permanently fixed to the suspension mechanism (I). The listed club management activities and other patient assistance may also be performed by the person caring for the patient on the walker. The handle (6) is designed and secured in the walker so that the person accompanying the patient can snuggle into the handle (6) without interruption, comfort and ergonomics. The handle (6) and the connecting element (2) and other elements of the walker help the person accompanying the patient in the walker (eg a physiotherapist) to control and help the patient to perform his / her actions properly.

Unlike the closest analogue document (WO2014001853A1), the present invention provides a patient attachment mechanism (I) having a different leg metal leg anchor assembly (13). In the closest analogue mentioned, the metal leg bracket is fastened to the patient's suspension mechanism (I) directly by screwing the patient's suspension mechanism (I) into place. In the present invention, there is an additional element between the patient's suspension mechanism (I) and the metal leg brace, a metal leg bracket attachment assembly (13). The mounting unit (13) resembles a rectangle without a single long edge. The mounting unit (13) is pivotally mounted to the patient hooking mechanism (I) approximately mid-way along its long edge. The attachment unit (13) can rotate about the attachment point relative to the horizontal plane. This allows the metal leg brace to move relative to the patient's suspension mechanism (I). As the patient moves, his torso and torso restraint moves with respect to the leg, and the design described above allows for such movement.

The pneumatic cylinder (1) consists of an elongated air reservoir having at least one air inlet, outlet opening near the ends of the cylinder (1), pistons, and other elements. By supplying air through one of the aforementioned openings, the increased air pressure in the container pushes the piston, one part of which forms one of the container walls. In this embodiment, the supply of air through the lower aperture results in a higher pressure pushing up the piston and the portion of the coupling to which the piston is attached. This raises the part of the connecting piece (2). The pneumatic cylinder (1) is pivotally mounted at one end to the walker frame (4) at one end and fixed at the other end to the connecting member (2) on an elongated support member closer to its end to which the ball hinge (3) is attached. The present invention uses at least two pneumatic cylinders (1) mounted on different sides of the walker to the different elongated retaining members of the coupling (2). Pneumocylinders (1) not only lift or lower the patient, but also act as a cushioning element which, depending on the pneumatic coupling method, constrains or freely guides during walking. As a person moves, the hips move up and down, precisely for this motion and require cushioning, much of which is accomplished by pneumocylinders (1).

The pneumatic cylinders (1) are connected via a pneumatic control panel (16) to a device for increasing the air pressure (eg a pump controlled by physical force, through air-flow channels (eg hoses, pipes, various joints, etc.), pump, electric compressor, etc.) ("the pump"). The pneumatic cylinders (1) are also interconnected by air flow channels via the pneumatic control panel (16). The pneumatic control panel (16) is actuated to the walker pneumatic system to perform the following functions:

could open the way for air to flow from the pneumatic cylinders (1), close the way for the air to flow out of the pneumatic cylinders (1), interconnect or disconnect the pneumatic cylinders (1).

When pumping the air to the pneumatic cylinders (1) to raise the patient to the required height, the air flow passages are closed to maintain a constant volume of air in the pneumatic cylinders (1). In one case, when the pneumatic cylinders (1) are not interconnected, the patient is treated with the same force exerted by the pressure in the pneumatic cylinders (1). Each pneumatic cylinder (1) contains an amount of air that cannot be varied. In this case, with the patient moving to one side or lifting one leg, the pneumatic cylinder (1) on the side of the raised leg will retain the patient - such a pneumocylinder (1) connection may be required to perform certain rehabilitation exercises. The pneumatic cylinders (1) act as two separate springs of equal strength. Alternatively, the pneumatic cylinders (1) are interconnected by air passages. In this case, the pneumatic cylinders (1) contain a single amount of air which can be freely distributed between the two pneumatic cylinders (1), i.e. air can flow freely from one pneumatic cylinder (1) to another. For example, when a patient is walking with one leg lifted, air will flow from the pneumocylinder (1) on the side of the raised leg to the other pneumocylinder (1), which allows the patient realistic stepping, one leg cannot be lifted and must support the body. . On the other hand, the total volume of air in both pneumatic cylinders (1) remains constant, which will always keep the patient in an upright position. When air can circulate between the two pneumatic cylinders, the person accompanying the patient will press down on the coupling (2) or handle (6) on one side of the walker, or the other on the other side of the walker will lift the pneumatic cylinder respectively. lowered down, viz for example, when the element is raised on one side of the walker, the pneumatic cylinder element on the other side will be lowered and vice versa.

Another important function of a walker that can only be performed by two pneumatic cylinders (1) and the air that can move between them is to hang the patient in the walker without a single hanging point. In the walk-through document provided in the nearest analogue (W02014001853A1), the patient's hanger is attached to the walker at a single point located in the middle of the hanger. Thus, as the patient shifts body weight from one leg to the other, it is also necessary to shift the weight through said anchorage point. It is somewhat reminiscent of cycling with the bicycle seat raised too high, where the cyclist has to jump over the raised seat in order to shift weight from one foot to the other. In the walker of the present invention, this unnatural movement is eliminated because the patient's suspension mechanism (I) is attached to the walker in at least two locations, approximately the width of a human shoulder. The aforementioned attachment of the suspension mechanism (I) and the two pneumatic cylinders (1) in the walker make it extremely close to natural walking movements.

The walker uses two pneumatic cylinders (1) and a bearer interconnection between the connecting member (2) allowing for a fairly accurate measurement of the air pressure in the two pneumatic cylinders (1) separately. In this way it is possible to calculate the force that the patient rests on the floor for each leg individually and to monitor the deterioration or improvement of the patient's leg support functions using one or other of the rehabilitation exercises.

Pneumatic control panel (16) for controlling air flows in the pneumatic system. The pneumatic control panel (16) consists of valves in the air flow passages and the handles for controlling those valves mounted on the front panel of the pneumatic control panel (16). In one embodiment, two handles are used. One handle is designed to open, close the pneumatic system, and open the system to change the amount of air in the system, closing the system to prevent air from escaping the system. Another handle is for connecting and disconnecting pneumatic cylinders (1).

Stable handle (7). In the front part of the walker, a stable handle (7) is permanently attached to the frame (4) (Fig. 5). Stable handle (7) for patient grip, elbows rest. The stable handle (7) of the present invention is analogous to that of the closest analogue (VV02014001853A1) except that the stable handle (7) is attached to the walker frame assembly (8) and the lower portion of the stable handle (7). The lower part of the stable handle (7), where it is attached to the walker frame (4), unlike the document of the nearest analogue, has two elongated elements which are connected by two horizontal elongated elements, thus forming a rectangle shaped like the base of the stable handle (7). The stable handle (7) sits with said short rectangular short edge on the mounting unit (8) in the frame. One corner of the short edge has a hole for a protrusion in the frame, the outer shape of which is close to the inner shape of the hole. In another embodiment, the base of the walker handle (7) may have a protrusion at its base, and the assembly attached to the frame (4) may have a protruding hole. In another embodiment, the corner of the mounting base of the handle (7) has a curved outwardly extending plane which, after insertion of the handle into its attachment position, is inserted behind an elongated member attached to the frame (4). One corner of the stable handle (7) is thus secured. By bending the stable handle (7) in the opposite direction to the fixed angle, the other part of the rectangular base is inserted into the mounting unit (8) in the frame (4) with the pivot pin. Said base of the rectangular stable handle (7) has a hole in the corner whose inner shape is close to the outer shape of said pivot pin. After inserting the base of the stable handle (7) into the base mounting unit (8) provided for it, the pin is inserted, which fits into the hole in the corner of the stable handle (7).

Walkers (10) attached to this description may be fitted with a foot control. The design and method of attachment of the leg control mechanism (10) are as described in the nearest analogue document (VV02014001853A1).

The patient suspension system (I) is fitted with a soft saddle, thigh soft brace (strap) system that secures the patient and secures the patient to the patient suspension mechanism (I). The whole system and the method of attaching it to the patient suspension mechanism (I) are the same as described in the nearest analogue document (VV02014001853A1). Said soft part has two bows (17) (Fig. 3) sewn into the pockets (14) of the suspension mechanism.

The arch-shaped members of the walker frame (4), the angle setting mechanism (9), the horizontal elongated member of the connecting element (2) may alternatively comprise two equal parts obtained by dividing the described whole parts in half by a plane containing X and Z axes. In this case, the resulting two separate halves of the parts are made in such a way that they can be fastened and made into one piece, for example, by screwing the two parts together. This combination of these elements makes it possible to split the walker in half, for example for convenient transportation. The entire rehabilitation walker can be disassembled by unscrewing the screws securing the two parts of the frame (4) and the connecting element (2) after removal of the patient attachment (I), the foot control (10) for convenient transport. In this way, the rehabilitation walker can be partitioned into symmetrical parts divided by a plane containing the X and Z axes.

The walker described in its entirety, compared to the one described in the nearest analogue document, is much better adapted for rehabilitation, less restricts the patient's movements, more efficiently loads the muscles needed for training, and more comfortable to use.

In order to illustrate and describe the present invention, the following is a description of the most preferred embodiments. It is not a detailed or restrictive description intended to determine the exact form or embodiment. The description above should be viewed as an illustration rather than a limitation. Obviously, many modifications and variations may be apparent to those skilled in the art.
