Description

Technical Field

[0001] The utility model belongs to the technical field of medical rehabilitation devices, and particularly relates to a resistance exercise device for lower limb function recovery. Background Art

[0002] The limb function exercise of limb fracture patients is crucial, especially for lower limb fractures. Good lower limb function exercise can not only prevent functional disorders such as muscle atrophy and joint stiffness, and restore limb function as soon as possible, but also prevent complications such as lower limb venous thrombosis and pulmonary infarction.

[0003] The exercise methods for lower limb function recovery include ankle pump exercise, ankle circumduction exercise, quadriceps femoris exercise, straight leg raise exercise, heel sliding exercise, etc. The above exercise methods can all be carried out in bed, which are self-exercises without other auxiliary equipment, and the exercise intensity is low.

[0004] As the lower limb function recovery exercise progresses step by step, it is very necessary to gradually increase the exercise intensity, which has a positive effect on promoting lower limb function recovery. Based on this, it is necessary to propose a resistance exercise device. When the patient performs a straight leg raise exercise or a heel sliding exercise, the resistance during the exercise process can be increased through this exercise device, the exercise intensity can be improved, and the lower limb function recovery can be promoted. Content of the Utility Model

[0005] The purpose of the utility model is to provide a resistance exercise device for lower limb function recovery. Through this exercise device, the exercise resistance during a straight leg raise exercise or a heel sliding exercise can be increased, the exercise intensity can be improved, and the lower limb function recovery can be promoted.

[0006] The utility model is realized through the following technical solutions:

[0007] A resistance exercise device for lower limb function recovery includes a vertical plate. A clamp is installed on the right side wall at the top of the vertical plate, and the vertical plate can be fixed on the tail plate of the hospital bed through the clamp;

[0008] It includes an elastic band and a reel mechanism for winding and unwinding the elastic band. The reel mechanism is installed on the left side wall of the vertical plate, and the elastic band can be wound and unwound by using the reel mechanism to adjust the length of the elastic band, thereby adjusting the resistance during the exercise;

[0009] It further includes an ankle strap that can be tied and fixed to the patient's ankle, and the movable end of the elastic band is connected to the ankle strap;

[0010] The patient can use this exerciser for straight-leg raising exercises or heel-sliding movements. During the process of raising the leg or bringing the heel closer to the buttocks, by pulling the elastic band with the foot and using the resistance exerted by the elastic band, the resistance during straight-leg raising exercises or heel-sliding movements can be increased, the exercise intensity can be improved, and the recovery of lower limb function can be promoted. By winding or unwinding the elastic band through the reel mechanism to adjust the length of the elastic band, the resistance of the elastic band during the exercise process can be adjusted.

[0011] Further, the fixture includes an L-shaped clamping plate. One end of the L-shaped clamping plate is fixed to the right side wall at the top of the vertical plate. An U-shaped clamping structure is formed between the L-shaped clamping plate and the vertical plate. At least two locking bolts spaced in the front-back direction are threadedly connected to the L-shaped clamping plate, and the central axis of the locking bolt is perpendicular to the right side wall surface of the vertical plate. A pressing plate is fixed to the tail end of the locking bolt, and the pressing plate is located between the right side wall of the vertical plate and the L-shaped clamping plate. When the vertical plate is attached to the tail plate of the hospital bed, the top of the vertical plate and the L-shaped clamping plate cooperate to clamp the top of the tail plate of the hospital bed. Rotate each locking bolt, use the pressing plate to press against the tail plate of the hospital bed, and the pressing plate and the vertical plate clamp the tail plate of the hospital bed, thereby fixing the vertical plate to the tail plate of the hospital bed.

[0012] Further, a support plate is fixed to the left side wall at the bottom of the vertical plate, and the support plate and the vertical plate form an L-shaped plate structure. The support plate can be supported on the bed surface to improve the stability of the vertical plate.

[0013] Further, fixing straps are fixedly connected to the rear side wall at the bottom of the vertical plate, the front end, and the rear end of the support plate. If the vertical plate cannot be fixed to the tail plate of the hospital bed through the fixture, or the ordinary bed has no tail plate, the vertical plate and the support plate can be bundled and fixed to the bed frame by using three fixing straps to ensure the stability of the vertical plate.

A guide groove extending in the front-rear direction is formed in the left side wall of the U-shaped guide plate, and the guide groove penetrates through the left side wall of the U-shaped guide plate. Two screws spaced in the front-rear direction are inserted into the guide groove. The right end of each screw is welded to the sliding plate, and the left end of each screw penetrates through the connecting plate and is threadedly connected with a nut for locking the connecting plate. Tightening the nut can fix the connecting plate on the U-shaped guide plate, and loosening the nut can slide and adjust the connecting plate in the front-rear direction. When the patient exercises the right lower limb, the reel mechanism can be adjusted to the front end of the U-shaped guide plate, and when the patient exercises the left lower limb, the reel mechanism can be adjusted to the rear end of the U-shaped guide plate.

[0016] Further, the ankle strap is composed of a wide strap and a thin strap. Both ends of the wide strap are fixedly connected with the thin straps, and the wide strap can be sleeved on the ankle and fixed by the two thin straps.

[0017] Further, pin shafts are fixedly installed on the outer side walls at both ends of the wide strap. A U-shaped movable plate is arranged between the ankle strap and the elastic band.

A connecting buckle is fixedly installed on the outer side wall of the middle section of the U-shaped movable plate, and the movable end of the elastic band is fixedly connected with the connecting buckle. After the ankle strap is fixed on the ankle, when the patient performs straight-leg raising exercise, as the lower limb swings, the U-shaped movable plate can rotate to facilitate pulling the elastic band. When performing heel sliding movement, the sole of the foot can be located inside the U-shaped movable plate. During the process of pulling the elastic band, pulling the elastic band through the U-shaped movable plate can keep the elastic band in the middle position and make the pulling force more balanced.

[0018] Further, the U-shaped movable plate is made of plastic and has a certain flexibility. In addition, the vertical plate, the fixture, the reel mechanism, the support plate, and the U-shaped guide plate are all made of plastic, which can control the overall weight of the exerciser.

[0030] During installation, the vertical plate 1 is attached to the tail plate of the hospital bed. The top end of the vertical plate 1 and the L-shaped clamping plate 2.1 cooperate to clamp the top end of the tail plate of the hospital bed. Rotate each locking bolt 2.3, and use the pressing plate 2.2 to press against the tail plate of the hospital bed. The pressing plate 2.2 and the vertical plate 1 clamp the tail plate of the hospital bed, so that the vertical plate 1 can be fixed to the tail plate of the hospital bed.

[0031] As Figures 1 to 4 shown, a U-shaped guide plate 12 extending in the front-back direction is fixedly installed on the left side wall of the vertical plate 1. A chute extending in the front-back direction is formed between the U-shaped guide plate 12 and the vertical plate 1. A sliding plate 11 is arranged in the chute, and the sliding plate 11 can move in the chute in the front-back direction; a guide groove 14 extending in the front-back direction is formed in the left side wall of the U-shaped guide plate 12, and the guide groove 14 penetrates the left side wall of the U-shaped guide plate 12. Two screws spaced in the front-back direction are inserted into the guide groove 14. The right end of each screw is welded to the sliding plate 11, and the left end of each screw penetrates through the connecting plate 3.1 and is threadedly connected with a nut 13 for locking the connecting plate 3.1. Tightening the nut 13 can fix the connecting plate 3.1 to the U-shaped guide plate 12, and loosening the nut 13 can slide and adjust the connecting plate 3.1 in the front-back direction;

[0032] When the patient exercises the right lower limb, the winch mechanism 3 can be adjusted to the front end of the U-shaped guide plate 12.

[0037] As Figure 1 , Figure 3 and Figure 5 shown in Figure 3 and Figure 5 , pin shafts 6 are fixed to the outer side walls of both ends of the wide strap 5.1. Specifically, a flexible plate is sewn and fixed inside the wide strap 5.1, and one end of the pin shaft 6 penetrates into the wide strap 5.1 and is welded or integrally formed with the flexible plate. The flexible plate and the pin shaft 6 are both made of metal materials or plastics; a U-shaped movable plate 7 is arranged between the ankle strap 5 and the elastic band 4. Both ends at the opening of the U-shaped movable plate 7 are respectively sleeved on the two pin shafts 6, and the U-shaped movable plate 7 can rotate around the pin shafts 6; a connecting buckle 8 is fixed to the outer side wall of the middle section of the U-shaped movable plate 7, and the movable end of the elastic band 4 is fixedly connected to the connecting buckle 8; after the ankle strap 5 is fixed to the ankle, when the patient performs straight leg raising exercises, as the lower limb swings, the U-shaped movable plate 7 can rotate to facilitate pulling the elastic band 4. When performing heel sliding movement, the sole of the foot can be located inside the U-shaped movable plate 7; during the process of pulling the elastic band 4, pulling the elastic band 4 through the U-shaped movable plate 7 can keep the elastic band 4 in the middle position and make the pulling force more balanced.

[0038] In this embodiment, as Figures 1 to 4As shown, a support plate 9 is fixed to the left side wall at the bottom end of the vertical plate 1. The support plate 9 and the vertical plate 1 form an L-shaped plate structure. The support plate 9 can be supported on the bed surface to improve the stability of the vertical plate 1.

[0041] The working principle of this embodiment is as follows:

[0042] When the patient uses this exerciser to perform straight leg raising exercises or heel sliding movements, the vertical plate 1 is fixed to the tailboard of the hospital bed by the fixture 2. Taking the right lower limb exercise as an example, loosen each nut 13, slide the reel mechanism 3 forward to adjust its position so that the reel mechanism 3 corresponds to the right lower limb. After the reel mechanism 3 is adjusted in place, tighten each nut 13 to fix the reel mechanism 3.

[0043] The patient or the caregiver binds and fixes the ankle strap 5 to the ankle of the patient's right lower limb to be exercised. The patient lies in a supine position and performs straight leg raising exercises or heel sliding movements. When raising the leg or bringing the heel closer to the buttocks, pull the elastic band 4 with the foot, and use the elastic band 4 to apply resistance during the exercise process, which can improve the exercise intensity and promote the recovery of lower limb function.

[0044] Before the exercise, the elastic band 4 can be wound or unwound by the reel mechanism 3 to adjust the length of the elastic band 4, so as to adjust the resistance of the elastic band 4 during the exercise process, which helps to gradually perform resistance exercises.
