Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an auxiliary walking device for the rehabilitation of patients with myasthenia gravis. Background Art

[0002] Myasthenia gravis is an acquired autoimmune disease with impaired neuromuscular junction transmission function. Patients often experience symptoms such as muscle weakness and easy fatigue, which seriously affect normal walking and self-care ability. In the process of rehabilitation treatment, the auxiliary walking device plays a key role in helping patients recover their walking ability and improve their quality of life. Currently, there are various types of auxiliary walking devices for the rehabilitation of patients with myasthenia gravis on the market, aiming to help patients support their bodies and reduce the burden on their legs, so as to carry out rehabilitation training.

[0003] Most of the existing auxiliary walking devices are in the form of crutches, walkers, etc. Crutch products generally provide single-point support for patients by means of hand-held support. The structure is relatively simple, usually consisting of a rod body and a handle, and some will be provided with anti-slip pads at the bottom of the rod body. Walkers are mostly frame structures with multiple support points, which can provide more stable support. Generally, they are equipped with wheels for easy movement, and patients can walk by pushing the walker. These devices mainly utilize the mechanical principle to transfer part of the patient's body weight to the support structure, reduce the pressure on the legs, and assist the patient to complete the movement.

[0004] In actual use scenarios, the existing auxiliary walking devices have many deficiencies. For example, in terms of helping patients with leg rehabilitation exercises, ordinary crutches and walkers cannot effectively exercise the leg muscles of patients. When patients try to bend their legs during the rehabilitation process to strengthen muscle strength, these devices cannot provide corresponding resistance for auxiliary exercise, resulting in patients missing the opportunity to exercise leg muscles during walking and affecting the rehabilitation effect.

[0005] In addition, the existing devices have limitations in adapting to the needs of different patients. Patients with different heights and different degrees of illness severity have different requirements for the support structure and support length of the auxiliary walking device. For example, when a taller patient uses a crutch or walker of conventional length, they will feel inconvenient due to the inappropriate support height, affecting the use experience and support effect; while for patients with more severe illness and extremely weak muscle strength, the conventional single-point support crutch cannot provide sufficient stability, easily causing the patient to fall, and cannot meet the diverse needs of patients, restricting the versatility and applicability of the device. Therefore, the present invention provides an auxiliary walking device for the rehabilitation of patients with myasthenia gravis to solve the deficiencies existing in the prior art. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an auxiliary walking device for the rehabilitation of patients with myasthenia gravis, which solves the problems that the existing auxiliary walking devices for the rehabilitation of patients with myasthenia gravis are difficult to help patients exercise leg strength and have poor adaptability to patients of different body types.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: an auxiliary walking device for the rehabilitation of patients with myasthenia gravis, including two groups of support rods and two support mechanisms. The number of support rods in each group is two. The top of each group of support rods is fixedly connected with a support plate, and a soft pad is arranged on the top of the support plate. Grips are fixedly connected to the adjacent sides of the two groups of support rods. Connecting rings are fixedly connected to the bottoms of the two groups of support rods. An activity rod is slidably connected to the inner side of the connecting ring. A protection block is fixedly connected to the top of the activity rod, and a mode switching mechanism is arranged at the bottom of the activity rod.

[0008] Preferably, the mode switching mechanism includes two U-shaped blocks and a conical block. The two U-shaped blocks are fixedly connected through a connecting piece, and the top of the connecting piece is threadedly connected to the bottom of the activity rod. Two cushion plates I are fixedly connected to the bottom of the U-shaped block.

[0009] Preferably, the inside of the conical block is threadedly connected to the bottom of the activity rod, and a cushion plate II is fixedly connected to the bottom of the conical block.

[0010] Preferably, an adjustment mechanism is arranged on the outer side of the connecting ring. The adjustment mechanism includes two connecting blocks. The two connecting blocks are arranged on the outer side of the connecting ring. Two jacks are opened in the inside of one of the connecting blocks.

[0011] Preferably, two combined holes II are opened in the inside of the connecting ring. A plug rod is fixedly connected to the outer side of the other connecting block.

[0012] Preferably, a plurality of combined holes I are opened in the inside of the activity rod. One end of the plug rod penetrates through one of the combined holes I and the inside of the two combined holes II, and is slidably connected to the inner side of the jack.

[0013] Preferably, a limit component is arranged on the outer side of the connecting block. The limit component includes magnetic attraction blocks. The outer sides of the magnetic attraction blocks are fixedly connected to the outer side of the connecting block, and the two magnetic attraction blocks attract each other.

[0014] Preferably, the support mechanism includes two side plates. A connecting seat is rotatably connected to the outer side of the side plate. A spring telescopic rod is installed between the two connecting seats. Two leg binding belts are arranged on one side of the side plate.

[0015] The present invention provides an auxiliary walking device for the rehabilitation of patients with myasthenia gravis. It has the following

[0016] Beneficial effects:

[0017] 1. In terms of the mode switching mechanism of the present invention, the bottom of the movable rod can be switched between different structures composed of a tapered block and a U-shaped block. The tapered block can be used as a conventional crutch mechanism to provide conventional support for patients. When using the U-shaped block, due to the backing plate fixedly connected to its bottom, the support range can be increased, providing a more stable support effect for patients who need a larger support area, meeting the needs of different usage scenarios. At the same time, the adjustment mechanism can flexibly adjust the support length according to the patient's height. By inserting the rod through different combination holes and cooperating with the magnetic attraction blocks to attract each other to stabilize the position of the movable rod, this design enables the entire device to adapt to patients of different heights, providing the most suitable support height for myasthenia gravis patients of different heights, thereby ensuring that patients obtain comfortable and effective support during use, improving the versatility and applicability of the walking assistance device, and providing great convenience for the rehabilitation training of patients.

[0018] 2. The spring telescopic rod in the support mechanism of the present invention can effectively assist the leg muscle exercise of myasthenia gravis patients. When the device is worn on the patient's leg and the two side plates are located at the thigh and calf positions respectively and fixed by the leg straps, the spring telescopic rod can exert an elastic force. On the one hand, it can overcome the difficulty that the patient cannot straighten the leg due to weak muscle strength, keeping the leg in a straight state, which helps the patient maintain the correct limb posture during walking and avoid inconvenience and abnormal walking caused by leg weakness. On the other hand, when the patient tries to bend the leg, the elastic force of the spring telescopic rod will produce a resistant effect, providing a certain resistance to the leg muscles, prompting the muscles to contract, thereby stimulating and exercising the leg muscles, helping to enhance muscle strength, and laying a foundation for the subsequent rehabilitation training and the improvement of the patient's independent walking ability.

[0023] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides an auxiliary walking device for the rehabilitation of patients with myasthenia gravis, including two groups of support rods 1 and two support mechanisms. The number of each group of support rods 1 is two. A support plate 2 is fixedly connected to the top of each group of support rods 1. A soft pad is arranged on the top of the support plate 2. Grips 3 are fixedly connected to the adjacent sides of the two groups of support rods 1. Connecting rings 11 are fixedly connected to the bottoms of the two groups of support rods 1. A movable rod 4 is slidably connected to the inner side of the connecting ring 11. A protective block 9 is fixedly connected to the top of the movable rod 4. A mode switching mechanism is arranged at the bottom of the movable rod 4. The mode switching mechanism includes two U-shaped blocks 5 and a conical block 7. The two U-shaped blocks 5 are fixedly connected by a connecting member, and the top of the connecting member is threadedly connected to the bottom of the movable rod 4. Two cushion plates one 6 are fixedly connected to the bottom of the U-shaped block 5. The inside of the conical block 7 is threadedly connected to the bottom of the movable rod 4. A cushion plate two 8 is fixedly connected to the bottom of the conical block 7. An adjusting mechanism is arranged on the outer side of the connecting ring 11. The adjusting mechanism includes two connecting blocks 14. The two connecting blocks 14 are arranged on the outer side of the connecting ring 11. Two jacks 15 are opened in the inside of one of the connecting blocks 14. Two combined holes two 12 are opened in the inside of the connecting ring 11. A plug rod 16 is fixedly connected to the outer side of the other connecting block 14. A plurality of combined holes one 10 are opened in the inside of the movable rod 4. One end of the plug rod 16 penetrates through one of the combined holes one 10 and the inside of the two combined holes two 12, and is slidably connected to the inner side of the jack 15. A limiting component is arranged on the outer side of the connecting block 14. The limiting component includes magnetic attraction blocks 13. The outer sides of the magnetic attraction blocks 13 are fixedly connected to the outer side of the connecting block 14. The two magnetic attraction blocks 13 attract each other.

[0025] Specifically, the auxiliary walking device for the rehabilitation of myasthenia gravis patients provided by the embodiments of the present invention mainly consists of two groups of support rods 1, two support mechanisms, a mode switching mechanism, an adjustment mechanism and other parts. Each group of support rods 1 has two, and a support plate 2 is fixedly connected to the top thereof. The soft pad on the top of the support plate 2 can increase the comfort of the patient's armpits. The grips 3 on the adjacent sides are convenient for the patient to hold to provide support. The support mechanism includes two side plates 17. A connecting seat 18 is rotatably connected to the outside of the side plate 17. The spring telescopic rod 19 installed between the connecting seats 18 plays an important role. When the support mechanism is worn on the patient's legs, the two side plates 17 are respectively located at the positions of the patient's thighs and calves. The leg straps 20 are used to wrap around the legs to ensure that the side plates 17 are located on the sides of the legs. The elasticity of the spring telescopic rod 19 can not only keep the patient's legs straight to overcome the problem that the legs cannot be straightened due to weak muscle strength, but also when the patient's legs are bent, the resistance effect generated by its elasticity helps the patient exercise the leg muscle strength and promote rehabilitation. The mode switching mechanism consists of two U-shaped blocks 5, a conical block 7, etc. The two U-shaped blocks 5 are fixedly connected by a connecting piece, and the top of the connecting piece is threadedly connected to the bottom of the movable rod 4. The two backing plates 6 fixed to the bottom can play a supporting role when switching to this mode and increase the supporting range. The inside of the conical block 7 is threadedly connected to the bottom of the movable rod 4. The backing plate 8 fixed to the bottom plays a supporting role when used as a conventional crutch mechanism. By switching the structure at the bottom of the movable rod 4 between the U-shaped block 5 and the conical block 7, different support requirements can be met, providing a variety of support methods for the patient.

[0026] Please refer to the attached Figure 1 - attached Figure 3 , the support mechanism includes two side plates 17. A connecting seat 18 is rotatably connected to the outside of the side plate 17. A spring telescopic rod 19 is installed between the two connecting seats 18. Two leg straps 20 are provided on one side of the side plate 17.

[0027] Specifically, the adjustment mechanism includes two connecting blocks 14. Two jacks 15 are opened inside one of the connecting blocks 14, which cooperate with the insertion rods 16 fixedly connected to the outside of the other connecting block 14. Two combination holes two 12 are opened inside the connecting ring 11, and multiple combination holes one 10 are opened inside the movable rod 4. One end of the insertion rod 16 can penetrate through one of the combination holes one 10 and the two combination holes two 12 and is slidably connected to the inner side of the jack 15. The magnetic attraction blocks 13 in the limit assembly on the outside of the connecting block 14 attract each other. This design enables the adjustment mechanism to flexibly adjust the support length according to the patient's height when adjusting the position of the movable rod 4. When the insertion rod 16 passes through the corresponding combination holes one 10 and combination holes two 12, the magnetic attraction blocks 13 attract each other, which can stabilize the position of the movable rod 4 and improve the adaptability of the entire device to patients of different heights.

[0028] Working principle: First, the support mechanism can be worn on the patient's leg. The two side plates 17 are respectively located at the positions of the patient's thigh and calf. The leg strap 20 is worn on the leg, and the two side plates 17 are worn on the side of the leg. The elasticity of the spring telescopic rod 19 can keep the patient's leg in a straight state, preventing the patient's leg muscles from being too weak to straighten. Moreover, when the patient's leg bends, the elasticity of the spring telescopic rod 19 will have a resistant effect, which can help the patient exercise the leg muscle strength. Then, the support plate 2 is located under the patient's armpit, and the palm holds the grip 3. The overall structure combined with the support rod 1 forms a special crutch, which can help the patient support the body. Moreover, according to the needs, the structure at the bottom of the movable rod 4 can be replaced. There is a conical block 7 as a conventional crutch mechanism, or it can be replaced with a U-shaped block 5 to increase the support range. Moreover, according to the patient's height, the movable rod 4 can be moved to adjust the support length, and the position of the movable rod 4 can be stabilized with the limit component and the insertion rod 16, so as to improve the adaptability of the overall structure to different patients.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
