Description

Technical Field

[0001] The invention relates to the technical field of medical care, in particular to a leg fracture care support for the elderly. Background Art

[0002] For patients with leg fractures, the recovery time is generally long. In order to avoid long-term inactivity leading to damage to leg muscles, especially for the elderly with deteriorating physical functions, rehabilitation exercises are usually required after a period of treatment. Using a nursing brace to achieve leg exercise to achieve the purpose of rehabilitation is a conventional means in the prior art. However, the existing leg fracture nursing brace has the following problems when used:

[0003] Publication No. (CN105662786B) involves a leg fracture nursing brace, which adds elastic support mechanisms on both sides of the legs and uses resistance to support the patient's legs to prevent the patient's entire legs from being fully stressed during walking training. However, the leg fracture nursing brace is not convenient for adaptive and stable adjustment according to road conditions. When walking and exercising, patients will inevitably encounter low-lying and raised roads. For these road conditions, if the resistance is not adaptively adjusted, the pressure on the patient's legs will increase or decrease. The increase in pressure can easily cause the patient's legs to be injured again, while the reduction in pressure will lead to a weakened exercise effect. Furthermore, the leg fracture nursing brace only achieves support protection, but is inconvenient to massage the patient's legs, reducing the effect of the patient's exercise.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original leg fracture nursing brace. Summary of the invention

[0005] The purpose of the present invention is to provide a leg fracture nursing brace for the elderly, so as to solve the problem that the existing leg fracture nursing brace proposed in the above background technology is not convenient for adaptive and stable adjustment according to road conditions, and it is not convenient for massaging the patient's legs.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention firstly utilizes the resistance generated by the elastic telescopic rod after being compressed to form a supporting force on the opposite surface, so that after the patient's sole touches the ground and stands, the body's gravity is shared by the elastic telescopic rod, thereby avoiding injuries caused by excessive force on the legs while satisfying the patient's walking exercise. In order to adapt to the exercise needs at different stages, the initial position of the installation sleeve is adjusted by rotating the gear ring, and then the initial compression degree and resistance of the elastic telescopic rod are adjusted. The adjustment is made according to the patient's rehabilitation needs at different stages and the force on the legs, thereby improving the practicality of the device.

[0022] 2. In the present invention, when the patient is walking, the support rod is forced to move upward, and the mounting sleeve is moved upward synchronously through the adaptive support adjustment component, so that the elastic telescopic rod maintains a stable compression degree. When the patient's sole contacts the ground when encountering low-lying and convex ground, the elastic telescopic rod can maintain a stable resistance and support force, which not only achieves a stable exercise effect, but also prevents the patient's leg from being injured. In the traditional technology, the elastic support principle is simply used, but it cannot be adjusted in real time according to the ground conditions, which affects the patient's exercise and rehabilitation effects, and the nursing function of the support is weakened;

[0023] 2. The present invention utilizes a massage drive component to achieve leg massage operations when the user is walking, utilizing the user's own gravity without the need for additional power, and the massage is stable, allowing the patient to massage the leg area during exercise, which helps to relax muscles, increase blood circulation, and further improve rehabilitation efficiency.

[0038] By using the massage drive assembly 19, the user can perform a massage operation on the legs every time he walks, thereby improving the exercise effect.

[0039] Working principle: When using the elderly leg fracture care support, Figure 1-6In the process, first, according to the patient's recovery degree, the toothed ring 121 is rotated, and the toothed ring 121 drives the gear 122 to rotate, and the gear 122 drives the screw 123 to rotate on the top of the rack 134, thereby driving the movable bar 6 to move vertically in the movable groove 5, and adjusting the height of the mounting sleeve 7 through the movable bar 6. At this time, under the elastic force of the elastic telescopic rod 8, the mounting sleeve 7 will move up and down, and the support rod 9 will not move under the obstruction of the limit sleeve 11 and the limit bar 10, thereby adjusting the initial compression degree of the elastic telescopic rod 8, and the position of the mounting sleeve 7 can be adjusted by setting a scale on the toothed ring 121. The user sets the upper mounting frame 1 on the thigh to fix it, and sets the lower mounting frame 3 on the calf. When walking, the bottom of the support rod 9 first contacts the ground and moves upward under the force. At this time, the upward movement of the support rod 9 is controlled by the tooth block 1 32 drives the first gear roller 131 to rotate, and the first gear roller 131 drives the second gear roller 133 to rotate. Under the conduction effect of the first gear roller 131 and the second gear roller 133, the rack 134 and the support rod 9 move synchronously, and the rack 134 drives the screw rod 123 to move upward, and the screw rod 123 drives the movable bar 6 and the installation sleeve 7 to move upward, so that the installation sleeve 7 and the support rod 9 can move upward synchronously. At this time, the elastic telescopic rod 8 can maintain a stable compression degree, and can provide a stable resistance. When the patient's sole steps on the ground, the support rod 9 stops moving upward. At this time, the stable resistance provided by the elastic telescopic rod 8 is used to achieve auxiliary support for the patient's foot, so that the force on the patient's foot is reduced, and the leg will not be injured while the purpose of exercise is achieved. Therefore, no matter whether the support rod 9 encounters a low-lying or raised ground, a stable support resistance can be maintained;

[0040] When the patient is walking, the support rod 9 is forced to move upward or reset, which can drive the cross column 194 to move in the side groove 193. Guided by the spiral structure of the side groove 193, the drive cylinder 191 can be driven to rotate, and the drive cylinder 191 drives the contact head 192 to rotate. When the contact head 192 moves to the position of the guide rod 17, the guide rod 17 is forced to drive the massage head 15 to extend out of the telescopic groove 14, and the spring 16 is stretched. At the same time, the massage head 15 contacts the airbag 18, so that the airbag 18 is squeezed and moves, thereby massaging the patient's leg area.
