Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary rehabilitation equipment, in particular to an orthosis for fracture patients. Background Art

[0002] There are many types of orthotics for fracture patients, among which traction beds are an indispensable type in orthopedic treatment. This type of limb traction bed achieves correction by traction of the patient's limbs. It contains both a ring for arm exercise and rehabilitation correction, and a counterweight block at the end of the bed to achieve leg traction.

[0003] However, in actual application, we found some problems. For example, when using rings for arm rehabilitation exercises, it may be difficult for patients with weaker strength to pull independently, thus affecting the correction effect. In addition, the adjustment flexibility of the counterweight block during the pulling process is insufficient. Although there are solutions for adjustment through motors in the prior art, the cost undoubtedly increases the burden on patients. The current orthopedic limb traction beds have relatively single functions and lack diversity. For this reason, we propose an orthosis for fracture patients. Summary of the invention

[0004] A technical problem to be solved by the present application is that the traditional orthopedic traction bed has a single function and a general effect, which makes patients less motivated to exercise.

[0023] 3. The traction adjustment component can be used by the patient during leg correction to adjust the traction force of the patient so that the patient can gradually adapt and can make smaller adjustments, which is more convenient than the existing method of adding weights.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-12The present invention provides a technical solution: an orthosis for fracture patients, comprising a bed, a traction frame arranged on the bed and a protective shell arranged on the side of the bed, and also comprising:

[0041] A square frame, which is movably arranged between the bed body and the traction frame, and two of them are arranged;

[0044] The traction adjustment component is arranged on the bed body and is used to provide tension support for the patient's rehabilitation. The tension can also be adjusted through the traction adjustment component so that the patient can gradually adapt to different degrees of tension.

[0045] The traction switching unit includes a pulley rod 1 arranged between the traction frames, two exercise ropes are movably arranged on the outer surface of the pulley rod 1, and belt loops are arranged at the bottom ends of the two exercise ropes for lifting the patient's legs.

The foot strap can be put on the patient's foot to correct the patient's leg while providing tension to the elastic traction rope.

[0048] A top plate is provided between the traction frames, a bare rod is movably provided at the bottom of the top plate, a rotating wheel is sleeved on the bare rod, a pull rope is wound inside the rotating wheel, and the pull rope is provided on the exercise ring, a support rod is provided on the end face of the bare rod, a connecting rod is rotatably provided on the other end of the support rod, a first straight cylinder is movably sleeved on the outer surface of the support rod, a pulley 1 is movably provided on the outer surface of the first straight cylinder, and the pulley 1 is movably provided on the exercise rope, that is, the exercise rope is wound on the pulley 1, a second straight cylinder is movably sleeved on the outer surface of the support rod, a pulley 2 is sleeved on the second straight cylinder, and the pulley 2 is movably provided on the suspension rope, so the suspension rope is wound on the pulley 2, and the provided pulley 1 and pulley 2 can allow the exercise rope and the suspension rope to be wound.

[0049] A plurality of limit rods are movably arranged between the first straight cylinder and the second straight cylinder, a plurality of slots are provided on adjacent end surfaces of the first straight cylinder and the second straight cylinder, a block corresponding to the plurality of slots is provided on the outer surface of the support rod, a switching wheel is rotatably arranged on the end surface of the first straight cylinder, a switching rope is wound around the outer surface of the switching wheel, the end surface of the switching rope is arranged on a square frame, an oblique groove is provided on the inner wall of the switching wheel, an oblique rod is provided on the outer surface of the connecting rod, the oblique rod is movably arranged in the oblique groove, a straight plate is arranged between the switching wheel and the traction frame, and a limiter for positioning and limiting the straight plate is arranged between the switching wheels, the oblique rod can move in the oblique groove by rotating it around the connecting rod, and the switching wheel is fixed, so that the connecting rod can be driven to move horizontally.

[0050] The limiting member includes a fixed column arranged on the side of the traction frame, a U-shaped groove is provided on the outer surface of the fixed column, an arc groove is provided on the outer surface of the fixed column to connect the U-shaped grooves to each other, a circular groove 1 is provided in the U-shaped groove, a circular groove 2 is provided on the inner wall of the U-shaped groove close to the arc groove, the U-shaped groove can be completely connected through the setting of the arc groove, and the distance between the circular groove 1 and the circular groove 2 is 180 degrees.

[0052] The traction adjustment component includes four connecting cylinders arranged in a protective shell, the inner walls of the four connecting cylinders are movably provided with piston disks 1, the inner walls of the four connecting cylinders are movably provided with lifting disks, strong tension springs are arranged between the four lifting disks and the corresponding piston disks 1, the tops of the four lifting disks are provided with connecting columns, the end faces of the four connecting columns pass through the inner walls of the corresponding connecting cylinders, two lifting ropes and two elastic traction ropes are arranged on the four connecting columns, and limiting disks are arranged on the outer surfaces of the four connecting columns, and the four limiting disks are tightly fitted on the tops of the corresponding connecting cylinders, the inner wall of the protective shell is provided with a main air pipe, and a secondary air pipe is arranged between the main air pipe and the four connecting cylinders, and the four connecting cylinders and the main air pipes are connected through the corresponding secondary air pipes. Replacing the traditional weights with strong springs has the same effect. The setting of the limiting disk can prevent the connecting column from falling, and by conveying gas into the main air pipe, the secondary air pipe can be used to enter the connecting cylinder, thereby changing the length of the strong tension spring, thereby changing different pulling forces.

[0053] A hose is provided on the end face of the main air pipe, and an air cylinder is provided at the other end of the hose. The air cylinder is arranged on the bed, and a rotating column is movably provided inside the air cylinder. A piston disk 2 is movably provided inside the air cylinder, and a threaded groove is provided at the bottom end of the rotating column. A threaded rod is rotatably provided at the top end of the piston disk 2, and the threaded rod is threadedly connected in the threaded groove. A guide groove is provided at the bottom end of the rotating column, and two guide rods are provided at the top end of the air cylinder. The two guide rods are movably provided in the corresponding guide grooves respectively, and the threaded rod is driven to rise and fall through the threaded groove in the rotating column, thereby squeezing and pulling the piston disk 2 to increase or decrease the gas in the air cylinder, thereby controlling the amount of gas in the main air pipe through the hose.

[0054] When using the device, first, when you need to exercise your lower limbs, you can hold the exercise ring 4 with both hands. When the exercise ring 4 is pulled, the pull rope 614 moves, and the pull rope 614 drives the inner rotating wheel 613 to rotate. The rotating wheel 613 drives the internal light rod 611 to rotate, and the light rod 611 drives the end surface support rod 618 to rotate, and the support rod 618 drives the outer surface clamping block 622 to rotate. Since the clamping block 622 is in the clamping groove 623 provided on the end surface of the first straight cylinder 619, it drives the pulley 67 to rotate through the first straight cylinder 619, thereby driving the exercise rope 62 wound on the outer surface to move, and the exercise rope 62 passes through the pulley rod 64 to drive the belt ring 65 to move, thereby exercising the patient's lower limbs;

[0055] When only the lower limbs need to be exercised, the square frame 3 can be pulled, and the square frame 3 will drive the switching rope 612 to move, and the switching rope 612 will drive the inner switching wheel 69 to rotate, and the switching wheel 69 will drive the inner inclined groove 615 to rotate, and the inclined rod 616 is arranged in the inclined groove 615, so that the connecting rod 617 can be driven to move, and the connecting rod 617 will drive the block 622 on the outer surface of the support rod 618 to move, so that the block 622 moves from the groove 623 on the end face of the first straight cylinder 619 to the groove 623 on the end face of the second straight cylinder 620. Synchronously, when the switching wheel 69 is rotated, the straight plate 610 on the end face will be driven to rotate on the end face of the traction frame 2, so that the iron ball 83 is squeezed in the circular groove 1 82, and the iron ball 83 will squeeze the lifting plate 84 to move in the sleeve plate 85, and at the same time squeeze the spring 1 86 to deform. At this time, during the rotation process, the iron ball 83 will be driven to slide in the U-shaped groove 81, so that the iron ball 83 moves to the circular groove 1 When the exercise ring 4 is pulled, the rotating wheel 613 is driven to rotate through the pull rope 614, and the rotating wheel 613 drives the pulley 68 to rotate, thereby driving the suspension rope 63 to move. The suspension rope 63 enters the protective shell 5 through the pulley rod 1 64 and the pulley rod 2 66. Since the suspension rope 63 is arranged on the end surface of the connecting column 710, when it is pulled, the strong tension spring 78 can be driven to deform, which can increase the tension, thereby achieving the exercise effect. When it needs to be reset, the square frame 3 can be pulled again to drive the switching wheel 69 to rotate, so that the iron ball 83 slides in the arc groove 89, thereby passing through the U-shaped groove 81. At this time, the spring 2 87 will be pulled to deform, and then the square frame 3 is released, and the spring 2 87 pulls the lifting plate 84 and the iron ball 83 to move into the circular groove 1 82 and reset to the starting position.

[0056] When traction correction is needed, the belt loop 65 can be put on the patient's foot, and traction is generated by the elastic traction rope 625 and the strong tension spring 78. When exercising the upper limbs, the sling 63 will drive the pulley rod 2 66 to rotate, and synchronously drive the elastic traction rope 625 to rotate. However, since the elastic traction rope 625 is elastic, it can be slowly reset, but there is no significant reduction in tension.

[0057] When the tension needs to be adjusted, rotating the rotating column 711 can drive the threaded groove 716 to move. Due to the guide rod 713 set on the end face of the piston disc 2 714 and the guide groove 712 at the bottom end of the rotating column 711, the piston disc 2 714 can be driven to pull the gas in the air cylinder 74, and the gas in the main air pipe 73 is pulled through the hose 72, and the piston disc 1 75 inside the connecting tube 71 is pulled down through the main air pipe 73, so that the strong tension spring 78 becomes. When it is necessary to pull the connecting column 710 to make the strong tension spring 78 deform again, a greater tension is required, otherwise the tension can be reduced.

[0058] Example 2: Please refer to Figure 13-14 The present invention provides a technical solution: two rings are provided on the outer surface of the traction frame, and side plates are provided on the outer surfaces of the two rings. A gear rod is provided between the two side plates, and the outer surface of the traction frame is tightly fitted to the outer surface of the elastic traction rope. The provided gear rod can effectively change the traction direction of the elastic traction rope so that the patient is subjected to horizontal pulling force as much as possible.
