Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a foot-powered training device for hemiplegic patients. Background Art

[0002] At present, hemiplegia, also known as hemiplegia, refers to the movement disorder of the upper and lower limbs, facial muscles and lower tongue muscles on the same side, which is a common symptom of acute cerebrovascular disease. Although patients with mild hemiplegia can still move, they often walk with their upper limbs flexed and their lower limbs straight. The paralyzed lower limbs make a half circle with each step. This special walking posture is called hemiplegic gait. Severe cases are often bedridden and lose their ability to live.

[0003] The existing Chinese patent with announcement number CN203303311U discloses an outdoor walking trainer for hemiplegic patients, including a bracket, a universal wheel is installed at the bottom of the bracket, and the bracket is provided with an armrest. The characteristics are: one side of the bracket is connected to a folding seat, a circular hole is provided at the bottom of the folding seat, a circular hole is provided at the bottom of the circular hole, and a circular ring frame is connected to the circular ring frame. A sealing bag is connected.

[0004] The inventors found that the increased muscle tension, decreased muscle strength and joint contracture on the hemiplegic side of stroke patients are the main reasons for the limited hip extension and knee flexion on the affected side. The asymmetry of movement between the hemiplegic side and the healthy side of stroke patients is an important factor affecting walking ability. The asymmetry of movement with the healthy lower limb is caused by the muscle tension, muscle strength and movement coordination disorders of the affected limb. The ground propulsion force is insufficient at the beginning of the swing phase of the affected side.

[0005] With respect to the above-mentioned related technologies, the inventors believe that many patients' walking speed stagnates in the later stages of rehabilitation due to insufficient ankle plantar flexion ability, and they cannot fully return to normal social life, and activities related to lower limb activities are basically out of their reach. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0022] Unless otherwise defined, the technical terms or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "one" or "an" and the like used in the patent application specification and claims of this application do not indicate a quantity limitation, but indicate the existence of at least one.

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The embodiment of the present application discloses a foot-powered training device for hemiplegic patients.

[0025] Reference Figure 1 A foot-assisted training device for hemiplegic patients comprises a running track body 1, a shoe insole 2 is arranged on one side of the running track body 1, and a groove 21 is formed on the shoe insole 2; and a power-assisting component 3 is arranged on the rear side of the shoe insole 2, and the power-assisting component 3 assists the patient; a connecting component 4 is arranged on the other side of the shoe insole 2, and the shoe insole 2 is connected to the patient's foot through the connecting component 4.

[0026] When in use, the insole 2 is connected to the patient's foot through the connecting component 4, and then the patient's sole is embedded in the groove 21 of the insole 2. During walking training, the power-assisting component 3 assists the patient in the process of walking, so that the patient's walking speed will not stagnate due to insufficient ankle plantar flexion ability in the later stage of rehabilitation, so that the patient can return to normal social life and even participate in activities related to lower limb activities. It can help hemiplegic patients to induce and assist patients in completing the pushing action of the lower limb on the hemiplegic side in the middle and late gait training of rehabilitation, so as to better restore the walking function.

[0027] Reference Figure 2-Figure 3 A first walking platform 11 and a second walking platform 12 are formed on the runway body 1. The horizontal plane of the first walking platform 11 is higher than that of the second walking platform 12. There are only guardrails 13 on both sides of the first walking platform 11 and the second walking platform 12. The guardrails 13 are fixed on both sides of the runway body 1. When performing recovery training, the patient puts his hands on the guardrails 13, then puts the normal foot on the first walking platform 11, and the foot that needs assistance is put on the second walking platform 12. By reciprocating between the runway body 1, the patient can perform assistance training.

[0028] The groove 21 is formed on the upper side of the insole 2. When in use, the sole of the patient's foot is embedded in the groove 21 of the insole 2, thereby preventing relative sliding between the sole of the patient's foot and the insole 2 when the patient is performing power training.

[0029] When in use, in order to achieve a better power-assisting effect, the rear side of the insole 2 is higher than the front side of the insole 2 , and the power-assisting component 3 is located at the rear side of the insole 2 .

[0030] The power-assisting assembly 3 includes a support plate 31, which is L-shaped as a whole, and a power-assisting spring 32 is arranged between the support plate 31 and the insole 2. The power-assisting spring 32 is arranged vertically as a whole, and three power-assisting springs 32 are arranged at intervals between the support plate 31 and the insole 2. One end of the three power-assisting springs 32 is connected to the support plate 31, and the other end is connected to the insole 2. During use, the patient's foot is assisted by the power-assisting spring 32, thereby improving the patient's tiptoeing ability.

[0031] In order to prevent the patient from slipping during walking, the designers made improvements and provided anti-skid pads 33 on the lower sides of the support plate 31 and the insole 2, and anti-skid grooves 331 on the side of the anti-skid pads 33 facing away from the support plate 31 and the insole 2. During walking, the anti-skid pads 33 are in contact with the ground through the anti-skid grooves 331, thereby preventing the patient from slipping during walking.

[0032] During training, in order to improve the stability between the patient's foot and the support plate 31 and the insole 2, a connecting component 4 is provided on the support plate 31 and the insole 2, and the connecting component 4 includes a male buckle 41 and a female buckle 42, and the male buckle 41 and the female buckle 42 are plugged together, and a strap 43 is provided on the male buckle 41 and the female buckle 42, one end of the strap 43 is respectively connected to the corresponding male buckle 41 and the female buckle 42, and the other end is connected to the corresponding support plate 31 and the insole 2. During use, in order to improve the adaptability of the strap 43, the strap 43 itself has elasticity. When the patient's foot needs to be fixed on the insole 2, the patient pulls up the male buckle 41 and the female buckle 42 on the insole 2, and then buckles them together, so that the male buckle 41 and the female buckle 42 are tightened on the patient's instep, and then the two male buckles 41 and the female buckle 42 on the support plate 31 are wrapped around the ankle, so that the strap 43 tightens the male buckle 41 and the female buckle 42 on the patient's ankle.

[0033] When the patient's ankle is tightened, the insole 2 will want to move closer to one side of the support plate 31. When the insole 2 is close to the support plate 31, the insole 2 will rub against the support plate 31, thereby affecting the normal use of the assist spring 32. After improvement by the designers, a guide groove 34 is opened on one side of the vertical direction of the support plate 31. The guide groove 34 is vertically arranged as a whole, and a guide block 35 is arranged in the guide groove 34. The guide block 35 is slidably embedded in the guide groove 34, and a connecting rod 36 is arranged between the guide block 35 and the insole 2. One end of the connecting rod 36 is connected to the guide block 35, and the other end is connected to the insole 2, thereby preventing the insole 2 from being tightened on the support plate 31.

[0034] During long training sessions, since the male buckle 41 and the female buckle 42 are tightened around the patient's feet by the strap 43, the male buckle 41 and the female buckle 42 may cause discomfort to the patient's feet. After improvements by the designers, an anti-wear block 44 is provided on the male buckle 41. The anti-wear block 44 is made of rubber, and a support groove 441 is formed on the anti-wear block 44. The support groove 441 faces the side away from the male buckle 41. When in use, the anti-wear block 44 contacts the patient's feet, thereby improving the patient's comfort during training.

[0035] The implementation principle of the foot-assisted ground-pushing training device for hemiplegic patients in the embodiment of the present application is as follows: the patient's feet are fixed by means of a male buckle 41 and a female buckle 42. During recovery training, the patient places his hands on the guardrail 13, and then places the normal foot on the first walking platform 11, and the foot that needs assistance is placed on the second walking platform 12. The patient can perform assistance training by reciprocating between the runway body 1, and during walking, the assistance spring 32 assists the patient's heel.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
