Monoblock type knee joint rehabilitation device
Technical field
This utility model relates to the technical field of medical instruments of knee joint recovery, is mainly used in rehabilitation after knee joint injury or arthritis.
Background technology
Osteoarthritis be caused by many factors articular cartilage fibrosis, chap, ulcer and depigmentation and the joint disease caused.Along with the quickening of Chinese aging process, osteoarthritis constantly increases for the impact of population health.At present, wearing the accreditation of brace Yi Bei international educational circles is one of standard care means of gonarthritis, in the different phase of osteoarthritis, all can adopt.
Summary of the invention
This utility model provides that a kind of structure is simple, and use safety, convenience, to alleviating pain, improve limbs stability, and there are the rehabilitation appliances of higher curative effect the aspect such as prevent from falling.
The purpose of this utility model is realized by following technical method:
This utility model is monoblock type knee joint rehabilitation device, by lower carriage (1), pressing plate (2), joint motion device (3), top board (4), train wheel bridge (5), draw ring (6) and adnexa thereof are formed, the joint motion device (3) of both sides is by being connected with train wheel bridge (5) with lower carriage (1) respectively with top board (4) with pressing plate (2), the elongated hole on draw ring (6) is passed afterwards with nylon adherent buckle binder, be fastened on upper and lower thigh and calf, simple to operation, regulate the kneed motion line of force at the volley, improve patient pain and stiff state.Wherein the junction, two ends of joint motion device (3) is involute teeth wheel construction, and gear coordinates guarantee stability of rotation without stuck.Movable inner splint (7) in joint motion device (3) and movable external splint (8) are equipped with boss, the angle of joint motion is limited at any time according to the requirement of knee joint recovery range of activity, can effectively control kneed range of activity, reduce the improper secondary injury brought of rehabilitation.
This utility model compared with prior art has the following advantages:
1. pressing plate (2) and top board (4) are wherein involute teeth wheel construction in one end, and gear coordinates guarantee rotation continuous and stable reliable;
The boss design of 2 movable inner splints (7) and movable external splint (8) can effectively control kneed range of activity;
3. simple to operate, imitating human body curve designs, and the large under shed of upper shed is little, human body surface of more fitting
This utility model structure is simple, easy to operate, handling ease and processing cost is low, weight and volume light and handy, is suitable for medical industry and applies.
