Description

Mechanism for assisting in supporting hemiplegic patient

Technical Field

The utility model belongs to the technical field of medical instrument, specifically be a mechanism of auxiliary stay hemiplegia patient.

Background

At present, with the pace of China entering the aging society and the change of life style of people, hemiplegia patients are quite common due to different causes of cardiovascular and cerebrovascular diseases and the like, serious patients often fall asleep and lose life capacity, and after cerebrovascular diseases enter a recovery period, if the hemiplegia patients do not take rehabilitation exercise in time, the hemiplegic side limbs of the hemiplegia patients become stiff and even malformed, which brings great pain to the patients. The existing patients are treated by acupuncture, massage and manipulation methods, and the treatment method has a certain rehabilitation effect on the patients, but the patients cannot independently complete the treatment; in addition, a variety of automatic rehabilitators are commercially available, which require a certain professional care provider or others with care knowledge to operate, and are generally expensive and not suitable for popularization. In the traditional clinical rehabilitation method, a rehabilitation doctor guides a patient to complete continuous passive movement one by bare hands or by using an auxiliary device, or applies appropriate resistance or assistance to guide the patient to move. The increase of the incidence rate of the cerebral apoplexy leads hemiplegia patients to be more and more, heavy and high-intensity training tasks bring heavy burden to treating doctors, and the intensity and the efficiency of patient training are influenced by the medical level of the treating doctors to a great extent. Therefore, it is very important to design an apparatus capable of assisting rehabilitation training instead of doctors by combining the rehabilitation training apparatus and related technologies with clinical rehabilitation medicine.

For the convenience of understanding, the working principle of the mechanism for assisting in supporting hemiplegic patients of the present invention is explained.

When using the utility model discloses a mechanism of auxiliary stay hemiplegia patient carries out hemiplegia patient's the training of standing up, the patient at first lies in this mechanism with sitting and standing the gesture. When a patient performs standing training, the leg plate of the mechanism adjusts the axial direction of the leg plate to be vertical to the ground under the action of the leg plate lifting device. The patient's foot is then acted on the running-board of leg board second end, and along with the gradual progress of process of rising up, the effort of patient's shank to the running-board increases gradually to the leg board telescoping device extension of driving leg board second end, until the running-board butt to ground, at this moment, the running-board will provide the ascending supporting role in vertical direction for patient's the process of rising up. After the pedal is abutted to the ground, the seat lifting device drives the seat to rotate around the hinge edge of the seat on the support body, so that the hip of a patient on the seat is pushed to rise. When the patient is completely in a standing posture, the seat plate and the leg plate are parallel to each other. Meanwhile, in the process of standing up of the patient, the backboard lifting device adjusts the deflection angle between the backboard lifting device and the seat board along with the back track of the patient. Finally, when the patient is in a standing position, the back plate, the seat plate and the leg plate of the mechanism are in the same plane and perpendicular to the ground. The procedure for the patient to sit is the reverse of the procedure described above and will not be described further herein. When the back plate, the seat plate and the leg plate are adjusted to be parallel to the horizontal plane, the mechanism can be adjusted to be in a prone position supporting state, so that some hemiplegic patients who only can carry out rehabilitation training in prone positions can use the mechanism conveniently. The device of the utility model is provided with the supporting plate structure which can be adjusted in a sectional way, thereby realizing the supporting function of patients under different postures, being capable of adapting to the differentiation requirements of patients with different disease conditions and improving the overall adaptability of the device; in addition, through setting up the telescopic running-board structure, can carry out automatic adjustment according to user's actual conditions, even user's foot does not leave the training that the device still can realize the gesture of standing.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
