Vacuum negative-pressure type orthosis applied to joint fixing

Abstract

The invention provides a vacuum negative-pressure type orthosis applied to joint fixing. The orthosis comprises a joint fixing sleeve body for positioning a limb to be fixed; the joint fixing sleeve body comprises an outer sleeve body, an inner sleeve body and a foam particle filler; the periphery of the outer sleeve body and the periphery of the inner sleeve body are in sealing connection, and thus a sealing space is formed between the outer sleeve body and the inner sleeve body; the foam particle filler is filled into the sealing space; an one-way exhaust valve for pumping air from the sealing space through a vacuum pump is arranged on the outer sleeve body. According to the vacuum negative-pressure type orthosis applied to the joint fixing, the space positioning effect is brought, any organization constriction effect is avoided, the local blood circulation is not influenced, the angle can be adjusted at random based on the patient condition, the treatment time can be controlled, the orthosis is light and can be carried around, the operation is simple and easy to be learnt, the cost is small, and a hospital and a home both apply.

Description

technical field [0001] The invention relates to an orthopedic brace. In particular, it relates to a vacuum negative pressure orthopedic brace applied to joint fixation aimed at the spatial positioning of specific joint functions of limbs. Background technique [0002] Patients with cerebral apoplexy and craniocerebral injury will have movement disorders of one side of their limbs, increased muscle tension, and joint contracture. During the rehabilitation process, such patients can only rely on the therapist to reduce muscle tension and improve joint spasm or contracture for a limited time every day. The effect of treatment cannot be maintained for a long time, so the time for patients to recover will not only be significantly prolonged, but also the final curative effect will be affected by the characteristics of the disease. Using an effective auxiliary brace will change this state of the patient. Most of the existing orthopedic braces rely on mechanical structures as fixi...

[0002] Patients with cerebral apoplexy and craniocerebral injury will have movement disorders of one side of their limbs, increased muscle tension, and joint contracture. During the rehabilitation process, such patients can only rely on the therapist to reduce muscle tension and improve joint spasm or contracture for a limited time every day. The effect of treatment cannot be maintained for a long time, so the time for patients to recover will not only be significantly prolonged, but also the final curative effect will be affected by the characteristics of the disease. Using an effective auxiliary brace will change this state of the patient

Most of the existing orthopedic braces rely on mechanical structures as fixing devices, which are complicated to operate, high in cost, cannot be carried around, and have limited application range; there are vacuum negative pressure fixing pad products, which are only used to fix the trunk or head of tumor patients during radiotherapy , there is currently no vacuum negative pressure positioning device for specific joints
