Description

BACKGROUND OF THE INVENTION The present invention relates to rehabilitation equipment used to alleviate gait disability and lower limb rehabilitation to restore functionality of limbs damaged by trauma or surgery. The invention can be used both in rehabilitation inpatient facilities and individually.

Exercise robotics systems based on exoskeleton type robots are known in the art. However, in practice, rehabilitation walkers with a frame with - usually - four wheels and a frame-mounted suspension that keeps the patient stationary or suspended between the front and rear rigid frame wheels are more widely used.

The rehabilitation walker described in U.S. Patent No. 6607202 has a frame with castors on which is mounted a spring-loaded stand to which a torso bracket is attached. The torso bracket pivots on the leg supports, which have a pivot in the knee area and a foot pad with shoe lock. The walker is used to support and facilitate walking in a person with walking disorder or cerebral palsy. However, this walker allows both knees to move only forward together and feet only to move backward together.

The rehabilitation walker according to EP2233120 A1 has a frame with wheels, a removable spring stand mounted on the frame in front of the patient and a patient suspension device which is connected to the stand by a coupling mechanism. The suspension has a lumbar bracket and leg brackets that are connected to the lumbar bracket. Footrests are attached to the footrests in the area of shoes and knees, consisting of moving elastic cords or straps, which are mounted on guides, such as pulleys, which are mounted on the front and rear of the frame. The ropes attached to the guides on the front of the frame are attached to the foot braces in the shoe area. The ropes, mounted on the guides fixed at the rear of the frame, are attached to the leg supports in the knee area. The footrest prevents both knees from moving forward together and feet moving backwards together. However, placing a seriously ill patient on such a walker is inconvenient, difficult to reach for the patient's anchorage. If the patient is overweight, the use of these walkers becomes complicated. Such walkers extend the use of rehabilitation walkers, but they are not accessible to seriously ill patients.

The closest analogue is a rehabilitation walker according to US 7150722, which has a frame with front and rear casters, a frame for a patient-mounted rack mounted on a patient suspension consisting of rigidly secured chest and torso holders, removable seat, lifting mechanism, a seated patient up to a standing and walking position, after the suspension is mounted on a rack, pivoting leg supports mounted on the waist bracket, having two metal straps connected by a knee swivel, and a knee and foot control with flexible elastic connector - ropes connecting the patient's knees to a special device at the end of the frame that prevents both knees from moving forward simultaneously. The front of the frame is fitted with another part of the control mechanism, which consists of flexible joints - ropes that are connected at one end to the shoe fastener in the foot area, which allows the shoes to rotate, and the other ends to the pulley mounted on the frame. The length of these ropes shall be chosen so as to prevent both feet from moving at the same time, but allowing one foot to move as in normal gait. In addition, there are two elastic ropes, one end of which is attached to the frame and the other to the guide pulley, which allows the elastic rope to move through it until the pulley reaches the stop on the rope. When the shoe is located farthest from the front of the frame, the stopper pulls the pulley towards itself and tightens the elastic rope. This happens when the patient is ready to take the step, {a stretched rope pulls the shoe forward, helping the walking process. This walker is used to support and facilitate walking for someone with walking disorders, such as cerebral palsy. However, the range of use of this walker is insufficient, for example, it is not suitable for rehabilitation after various injuries and learning to walk. This is due to the lack of sensitivity of the patient attachment and the slight knee lift and foot pushing effect.

The object of the invention is to provide a rehabilitation walker that accomplishes such goals;

ensure safe and convenient patient placement, regardless of degree of disability, weight and height;

have a more responsive suspension that minimizes patient movement while providing a comfortable and safe upright position and helps the patient perform the most correct gait movements with walking and knee-lift mechanisms;

allow the patient to perform various physical exercises in an upright position to stimulate faster recovery;

help to create feedback between the patient and the physiotherapist in order to judge the patient's health and the effectiveness of the exercises used;

provide comfortable working conditions for the physiotherapist or the person accompanying the patient;

would be disassembled to transportable modules. This would allow the walker to be used not only in stationary areas, but also in individual spaces around the home (yards, stadiums, parks, etc.).

The objects of the invention are realized in a rehabilitation walker, which has a set of features set forth in the claims.

The rehabilitation walker according to the present invention comprises a frame with rotatable front axles, wheels and rear wheels, a frame-mounted lifting mechanism having a manual lift, a patient suspension having torso bands, and a knee and foot control mechanism.

What is new is that the rehabilitation walker has an additional lifting and cushioning mechanism, the suspension has a carrier member attached to the auxiliary lifting and cushioning mechanism, and that the vertical lifting mechanism (31) has an auxiliary lifting and cushioning guide.

The auxiliary lifting and damping mechanism comprises a pneumatic cylinder coupled to an air compressor, which may be a foot or battery pump, and a quadrangular vertical plane frame having parallel arms and which are pivotally connected to the carrier and pivot of the suspension device, can be guided by the guide wheels. The said movable frame has two lower arms, between which can be moved a pneumatic cylinder stem connected to the upper arm of the frame through a pivot. The pneumatic cylinder body holder is connected to the slider through the pivot. The pneumocylinder stem responds to the change in weight as the patient moves, acting as a shock absorber up or down. The compressed air in the pneumocylinder pushes the attachment upwards while holding the patient steady. The compressed air pressure in a pneumocylinder can be measured to know what load the patient's feet are under during their support.

The upper lever of the lifting and cushioning mechanism has a lever that is used to steer the walker or to accompany the patient while he is on the left or right side of the wheelchair.

The hitch has swivel brackets that are pivotally mounted with respect to the X axis. Torso straps are fastened to the suspension brackets, swivelable in relation to the Y axis, and a saddle is fastened by means of buckles and belts with the leg thigh fastenings attached to it. This suspension divides the patient's weight into three points of contact. The majority of the patient's weight is then on the saddle and the remaining weight is on the leg thighs. The suspension brackets can move relative to one another, reducing or increasing the distance between the waistbands. This enables the patient's suspension to be precisely fitted to the patient's torso. The X-axis and Y-axis rotation of the attachment allows the patient to tilt, wiggle in all directions while minimizing patient motion.

If the patient is unable to hold the body upright, the attachment shall have a head and chest bracket attached or detached as required, consisting of a head restraint mounted on a rack and a patient strap that surrounds the carrier.

The top link of the lifting and cushioning mechanism may have a retractable or retractable bar attached to the support member of the suspension device via a pivot. This allows the patient to be tilted forward or backward by the suspension device.

If the patient is not coordinating leg movements, the knee and foot control is used, which has two vertical brackets with an integrated pulley system, which are elasticly connected to the patient's knee and foot ligaments. The patient's thigh ligaments are joined by elastic members with pulleys mounted on a hoist. This knee and foot control mechanism greatly facilitates the coordinated lifting and pushing of each foot and the straightening of the foot forward. The system of pulleys in the vertical brackets results in coordinated lifting of the feet across the road at double the force of the foot.

If the patient has, in addition to impaired gait coordination, leg musculature and knee ligament disorders, then the patient's suspension brackets are hinged with two metal bands, including knee-adjusters, and additional patient ligaments for the thigh and lower leg. area. The metal parts of the leg restraints, in the region of the thigh, joined by elastic members with pulleys mounted on the hoist. The knee and foot control is connected by elastic members to the parts of the leg supports in the lower leg and foot area.

The Rehabilitation Walker has a removable armrest with soft support for the elbows, which is mounted on a height-adjustable stand that is screwed to the walker frame.

The rear wheels of the walker frame can rotate about their axis. This allows the patient, who is anchored in the walker, to easily move in any direction, without rolling the arches, and rotate while standing at a single point 360 degrees about their axis.

A rehabilitation walker having the features of the invention described can be easily disassembled and transported by a light machine.

The invention will be explained in more detail with reference to the accompanying drawings in which:

FIG. Figure 13 shows the connection of the leg supports to the knee and foot area control mechanism.

The rehabilitation walker 1 (Fig. 1, Fig. 2) consists of a frame 11 with two front wheels 12 and two rear wheels 13, which can all rotate about their axis and has brakes (not shown), a curved tube 14 connected by bolts 15 to the frame. 11, armrest 21 with soft supports 22 for elbows support and mounting fingers 23, a vertical lifting mechanism 31 consisting of a guide 32 having a handle 33 mounted perpendicularly to the frame 11, and a manual hoist 34 with worm gear and handle 35, a patient suspension device 41. (Figs. 2 and 3 to 5), a lifting and damping mechanism 51 and a knee and foot control mechanism 61.

The front 12 and rear 13 wheels of the walker 1 frame 11 can rotate about their axis, fix the direction of rolling and be braked. This allows the pedestal patient to easily move in any direction, without rolling arcs, and turning at a single point 360 degrees about their axis.

Hand holder 21 has a height-adjustable stand consisting of a vertical tube 24 attached to the frame 11 and a sliding tube 25 in the tube 24 secured by a screw 26. The fingers 23 of the hand holder 21 are fastened by a screw 27. Adjustable by the hand holder 21 height. If the hand holder 21 is not used, it can be easily removed.

The patient suspension device 41 (FIGS. 2, 3 to 5) has suspension brackets 42 and curved torso belts 43 to which a soft saddle 46 is attached with buckles 44 and belts 45 with soft leg thighs 47 attached thereto. the bracket 48 is used to fasten the torso straps 43 to the hinged brackets 42. If necessary, the bracket 48 is also used to fasten the leg supports (Fig. 13). The waistband 43 is sewn into a soft waist belt (not shown). Such a suspension divides the patient's weight into three points of contact. The majority of the patient's weight is on the soft saddle 46 and the remaining weight is on the leg thigh support 47. This way, the patient does not feel over-tightened at the hanging points and can walk in the walker for the duration of the procedure.

The primary function of the Patient Hanger 41 is to keep the patient in an upright position safely while minimizing torso movements. The suspension brackets 42 can move relative to one another, reducing or increasing the distance between the torso belts 43. This allows the patient suspension device 41 to be precisely adapted to the patient's torso. The torso straps 43 may rotate about the Y axis (Fig. 4) and the suspension brackets 42 may rotate about the X axis (Fig. 5). Such rotation of the suspension device 41 about the X and Y axes allows the patient to tilt and twist the torso in all directions, while minimizing patient motion.

The lifting and cushioning mechanism 51 (Figs. 2, 6 to 8) consists of a bearing member 511 of a suspension device 41, a pneumatic cylinder 512, and a quadrangular vertical plane frame formed by parallel levers 513 and 514 connected via hinges 515 to the bearing member. 511 and through pivots 516 with a slider 517 which can be rolled through a guide 32 with wheels 518. The pneumatic cylinder 512 shaft 519 is mounted to a lever 513 by a pivot 520, its body via a pivot 521 on a slider 517. The air to the pneumatic cylinder 512 is supplied by sock or battery pump.

FIG. 6 and FIG. 7 shows how the patient is positioned from a sitting position. By depressing valve 523 which is schematically shown in FIG. 7, from a pneumocylinder

Residual air 512 is discharged and stalk 519 descends with lever 513. If the patient is seated very low, the lowering stroke of the patient hitch 41 can be increased by turning handle 35 of the hoist 34, then the lifting and damping mechanism 51 is lowered with the hinged wheel 418. 2) with guide 32 down.

The lifting of the patient suspension device 41 is effected by pumping air with a compressor 522. The shaft 519 of the pneumatic cylinder 512 then rises upwards by pushing the lever 513 attached to the pivot 520. The process described above all repeats. The only difference is that when pumped by compressor 522, the lifting and damping mechanism 51 lifts the patient suspension device 41 attached thereto via carrier element 511 while pumping air by compressor 522 until the levers

513 and 514 are horizontal. If the lifting height of the attachment device 41 is not yet sufficient, the height 34 can be increased by turning the handle 35 of the hoist 34.

Pneumocylinder 512 pushes compressed air up through its stem 519 suspension device 41 while holding the patient with constant force. As the patient moves, his body moves sideways, forward, backward, up, or down. As the patient walks, the leg 519 responds to the change in weight by moving up (Fig. 6) and down (Fig. 7), acting as a shock absorber. The air in the pneumatic cylinder 512, pressurized by the stem 519, acts as a spring, smoothly reproducing the amplitude of the human stride, consisting of a vertical displacement of about 100 mm (Fig. 8).

The compressed air pressure in the Pneumocylinder 512 is measured to know what load the patient's feet are bearing during their support. The support force Fr will decrease if we pump compressor 522 into cylinder 521, which pushes shaft 519 to lift carrier member 511 together with attachment device 41. The patient is lifted by a soft saddle 46 and soft thigh straps 47 attached thereto. provides a secure and patient-responsive walker-to-patient connection. When the patient's feet are raised from the ground, the lift force F generated by the air pressure is the amount needed to lift the patient off the floor and keep him in that position. That is, the patient weight force Fs = F * k and the foot support force Fr = 0. In addition to the patient weight force Fs in the pneumatic cylinder 521, the lift force F is required to lift the lifting and damping mechanism 51 and the attachment device 41. This force depends on the lifting and damping mechanism 51, the weight of the suspension device 41 and the push angle of the shaft 519. We will call this dependency a "k".

The air pressure in cylinder 521 is measured by a schematic pressure sensor 623 (Fig. 8), the signal of which is transmitted to an analog-to-digital converter 524 having a digital indicator (not shown). The pressure value multiplied by the selected factor k is shown on the converter 524 indicator. The pressure value corresponds to the difference in kilograms between the patient's weight and the air pressure of the push rod 519. If the patient is lowered to rest on the floor with the feet resting, then indicator 524 will display a value equal to the foot support force Fr, Fr = Fs- F * k> 0. This allows the patient foot support force Fr. This feature of walkers can be used as a test to see if the treatment method used improves the patient's ability to perform a variety of walking exercises while maintaining the assigned frame weight Fr. It is also possible to measure the difference between the support forces of both legs during walking. If there is such a difference, it means that one of the patient's feet relies on a lower (greater) force on the floor. This asymmetry can be treated as long as the support forces of both legs converge.

If the patient is unable to hold the body upright, a head and chest bracket (Fig. 9) consisting of stand 525 with head bracket 526, bolted 527 to bush 528, and chest height strap 530 are used. Head bracket 526 is height adjustable by unscrewing locking bolt 529 and, as needed, by moving the head restraint 526 up or down. The belt 530 surrounds the patient's chest through the carrier member 511 and engages. The lever 513 of the lifting and damping mechanism 51 has a handle 531 which is used to drive the walker. Handle 531 facilitates driving when the walker is used by an accompanying person on the left or right of the patient.

The lifting and cushioning mechanism 51 allows the patient suspended in the suspension device 41 to be inclined forward or backward (FIG. 10). This is done by inserting screw 532 into the hole corresponding to the desired angle, marked -K, O, + K, + 2K. In this operation, the bar 533 is retracted or retracted and the lever 513 is extended or shortened by a distance X. The bar 533 secured through the pivot 515 to the carrier member 511 is pushed and rotated about its axis 515, the carrier member 511 inclined at desired angles. stand 525 with head 526 and torso 530 brackets attached. This feature is needed to allow a patient with poor torso control to move their center of gravity "G" forward and start moving.

If the patient does not coordinate leg movements, a knee and foot area control mechanism 61 (Fig. 2, Fig. 11, Fig. 12) is used, which has two vertical brackets 612 which are bolted 63 to a curved tube 14. In the upper part of the brackets 612 A system 614 connected by elastic members (ropes or rubbers) (a) and (b) to the patient's knee ligaments 615 and 616. In the lower portion of the brackets 612, the system of pulleys 617 is joined by the elastic elements (c) and (d) to the foot ligaments 618; 619. The thigh ligaments 620 and 621 of the patient are joined by elastic members (e) to the pulleys 622 mounted on the hoist 34 (Fig. 11). The elastic members (f) connect the toe region of the patient's toes with the elastic members (c) and (d).

The patient's legs are interconnected by a system of elastic members (a, b, c, d, e) passing through a system of pulleys A 'and B' (Fig. 12). Pushing the walker forward (in the direction of the arrow) causes the patient, by means of mechanism 61, to move the feet and knees in turn, as schematically shown in FIG. 12. Suppose the patient's weight, or part of the weight, on the right leg with ligaments 621, 616, 619 rests on the floor and forms a greater friction with the floor than the left leg with ligaments 620, 615, 618 that the patient wishes to reposition. As the walker is moved forward, the patient's body is pushed and the right leg with ligaments 621, 616, 619, which has greater grip on the floor, remains in place while conveying the elastic member (c). As the walker moves forward, the tensile effect of the elastic member (c) is obtained by the force Ft. The elastic member (c), through the pulley system B ', is subjected to a double force Ft * 2 to stretch the elastic member (a), which is connected to the left leg via a ligament 615 in the knee region. This action results in lifting the left leg over the ligament in the 615 knee region. At the same time, the right foot, which acts as an anchor, pulls a force Ft 'over the elastic member (b) through the elastic member (b) through the pulley system A' and the flexible member (d) through the elastic member (618).

The result is stretching the left foot with the force of Ft'12 forward, the cumulative effect of this is lifting the left foot across the knee and pushing and straightening the foot forward, i.e. the left foot is moved forward and straightened, preparing it for body support.

This is the step taken by the patient entrenched in the walker. Then the cycle repeats itself. In this way, a patient with impaired gait function can perform an action that is as close as possible to gait. The elastic member (e) passing through the pulleys 622 engages both legs in the knee region through the ligaments 620, 621 and prevents the knees from moving forward together, in other words, preventing the legs from bending over the knees together. The energy required for the patient to walk through the mechanism 61 is provided by the physiotherapist by pushing the walker. Such interrelationship can be used as a feedback to judge the patient's physical condition. If pushing the walker requires less energy from the person pushing it, then the patient in the walker does part of the work with his or her feet while facilitating pushing. The elastic members (f), which connect the toe area of the toes, prevent the front of the sole from sticking to the floor during walking, making it easier for the patient to walk. The push effect of the walker can be achieved by placing it on the treadmill. The walkers 1 and 12 are then placed on a treadmill with the brakes applied and the patient is left to step on a sliding bar (not shown).

If the patient has, in addition to impaired gait coordination function, leg musculoskeletal disorders, a known leg rest, such as that described in US 6607202, may be used. 13 schematically illustrates the attachment of a leg brace to a knee and foot area control mechanism 61.

The leg supports 71 (Fig. 13) are shamrically secured to the patient suspension device 41 (Fig. 2) by means of the fastener 48 (Fig. 3, Fig. 4). The leg collar 71 has metal straps 72 and 73 including a knee bend adjuster 74, additional patient anchor points 75 in the thigh region and ligaments 76 in the shin region, which engage the legs in a fixed manner with the leg collar 71 in the thigh and shin region. This hanging causes the patient's weight to be distributed over five hanging points and the patient feels almost no pressure. This is needed when the leg muscles and ligaments are atrophied, there is a high potential for dislocation, and when the skin is very sensitive to damage. The leg support 71 has its soles 77 which are fastened to the patient's shoe 78 with laces. If the soles are not needed, they can be removed.

The elements of the leg supports 71 are connected to the elastic members (a, b, c, d, e) of the knee and foot control mechanism 61. The metal strap portion 72 located between the laces 75 in the thigh region and the laces 76 in the calf region is joined by elastic members (e) with pulleys 622 mounted on a hoist 34. The ligaments 76 in the calf region are connected by elastic members (a) and (b) and the shoe 78. ligaments connected to elements (c) and (d). The soles of the leg supports 71 are joined by the elastic members (f) to the members (c) and (d) in the toe region 77.

The rehabilitation walker 1 can be easily disassembled (Fig. 2). By rotating the lever 723 of the lifting and damping mechanism 51 from position B to position B ', the patient suspension device 41 with its centering support member 49 may be pushed out of the bushing 724. The bushing 724 attached to the carrier element 511. The suspension device 41 may rotate the X-axis of the retaining member 49, when engaged, by means of a handle 723 in a bushing 724.

The lifting and damping mechanism 51 can be pushed out by unscrewing the cover 525. This mechanism then rolls out of the guide 32 of the rack 31 as it rolls on the wheels 518.

The frame 11 is unscrewed from the vertical lifting mechanism 31 by a guide 16 (Fig. 1).

The knee and foot area control mechanism 61, together with the tube 14, is pushed out of the frame 11 by unscrewing the bolt 15 or by removing the bolt 63 from the tube 14 holding it.

Once the rehabilitation walker 1 has been dismantled, it can be placed in a passenger car or other vehicle and transported to a designated walking area.
