Description

Rehabilitation training device for assisting hemiplegic patient to transfer

Technical Field

The utility model relates to a rehabilitation training device for patients with hemiplegic lower limb movement dysfunction, which belongs to the field of medical equipment.

Background

Most of patients after stroke have different degrees of hemilateral limb movement dysfunction, wherein the hemilateral lower limb dysfunction makes the stroke patients difficult to complete actions which can be easily completed by normal people, wherein the sitting and standing transfer is a basic activity in life, the activity is closely related to balance and walking ability, and the activity is also the basis for the stroke hemiplegia patients to realize daily functional activities such as bed and chair transfer, chair and toilet transfer and the like, and is the daily activity with the highest falling probability for the stroke hemiplegia patients. The function of a patient with hemiplegia after stroke is generally influenced, so that the daily living capacity of the patient is seriously influenced, the activity and social participation of the patient are limited, the living quality of the patient is obviously reduced, and the burden is brought to families and society.

Sit-stand transfer involves primarily changes in the joints, muscles and center of gravity of the lower extremities. The cerebral apoplexy hemiplegia patient often has more serious clinical characteristics such as weak muscles of lower limbs on one side, poor balance capability, hypoesthesia of sensory input and the like, and the patient usually has difficulty in starting, difficult speed control after starting and unbalanced body during sitting-standing transfer, so that the patient always shows an abnormal movement mode that the body deviates to the healthy side and the healthy side bears excessive load in the whole sitting-standing transfer process, the knee joints on two sides also have the difference on one side in the movement, and the body gravity center and the side swing of the pressure centers of two feet are increased. These abnormal movement patterns increase instability, increase energy consumption, and also cause overstressing of the healthy knee joints leading to accelerated incidence of gonarthritis.

The difficulty in starting the sitting-standing transfer is the biggest problem in the rehabilitation therapy of hemiplegia. When the patient is transferred in a sitting-standing way, the hip joint and the knee joint are required to be straightened, the force required by the initial 30 degrees is the maximum, and in the subsequent movement, the required force is obviously reduced, so that the difficult problem of starting the hemiplegic patient in the sitting-standing task is generally solved. The change of the tangential component of gravity after the seat is inclined is utilized to generate a proper gliding effect, which is beneficial to the starting of the standing action; meanwhile, the armrest with proper height can make the hemiplegic patient start sitting-standing transfer by utilizing the strength of the upper limb better and maintain balance.

At present, the height of the seat of sitting on the market shifts training product or for adjusting the seat, or for sitting the focus change detection in the station transfer state, does not have the design of adjusting seat angle and handrail height yet, also does not change detecting system's combination with the focus and uses, keeps the speech suggestion that the action symmetry is mainly through therapist training, can't accomplish accurate aassessment and suggestion, simultaneously the utility model discloses still combine sense of hearing and visual biofeedback system, can satisfy the demand of individualized training.

Disclosure of Invention

An object of the utility model is to provide a rehabilitation training device of supplementary hemiplegia patient transfer to defect among the prior art, solve present sit stand transfer rehabilitation training device function singleness and design and do not consider different patients to sit the transfer degree of difficulty of standing, do not relate to and combine sense of hearing and vision biofeedback system, fill the product blank of standing transfer rehabilitation training device to hemiplegia patient's individuality.

In order to achieve the above object, the present invention provides the following technical solutions:

a rehabilitation training device for assisting the transfer of a hemiplegic patient comprises a seat adjusting system, a sitting position pressure measuring system, a plantar pressure measuring system, an auditory and visual biofeedback system and the like; the seat adjustment system is adjustable, including adjusting the height, angle, and height of the armrest of the seat; the seat is provided with a seat angle sensor arranged on a seat surface and used for detecting the inclination angle of the seat surface; the seat pressure measuring system is connected with the auditory and visual biofeedback system; the plantar pressure measuring system is connected with an auditory and visual biofeedback system; the visual biofeedback system comprises a computer processor and a display screen; the computer processor can obtain pressure distribution data and calculate bilateral pressure symmetry, and the display screen is connected with the computer processor and used for displaying the sitting pressure, the plantar pressure and the bilateral symmetry degree of the patient so as to prompt the hemiplegia patient to carry a load as symmetrically as possible.

The chair has the advantages that necessary assistance and prompt are provided in the transfer exercise training, and particularly for patients who are difficult to finish transfer in sitting and standing, the starting difficulty and bilateral asymmetry in the sitting and standing transfer of stroke patients are improved by adjusting the height, the angle and the height of the armrests, so that the patients can finish the sitting and standing transfer more smoothly; meanwhile, the height, the angle and the height of the armrests of the seat can be adjusted, the sitting and standing transfer difficulty is increased, and the rehabilitation training effect is enhanced. The position change of the pressure center also reflects the symmetry of the load and the expression of the trunk kinematics, so the change of the sitting position pressure and the sole pressure in the whole sitting and standing transfer process is observed, the change of the stability of the patient can be reflected, and the time node is judged to be relatively unstable. Through the pressure measurement analysis, combine sense of hearing and vision biofeedback system to make the hemiplegia patient who has limbs movement dysfunction accomplish the symmetry as far as possible and bear a burden, avoid healthy side knee joint gonitis to appear, provide the removable guardrail that prevents to fall simultaneously, reach recovered final purpose under the prerequisite of guaranteeing safety to provide the basis for the risk assessment of falling and taking treatment strategy.

The utility model has the advantages that: the utility model has novel structural design, simple principle and more humanized training requirement-based design, can adjust the height, angle and armrest height of the chair, can carry out symmetrical load bearing as much as possible for hemiplegic patients with limb movement dysfunction by pressure measurement and analysis and combining with an auditory and visual biofeedback system, avoids the knee joint inflammation of healthy side, provides good training for patients and achieves the final aim of rehabilitation; meanwhile, the detachable guardrail is further arranged, so that a patient can conveniently enter the equipment to train and play a role in protection.
