Gradual inflatable shoulder joint brace realizing self-control

Abstract

The invention belongs to the technical field of medical assisting apparatus and particularly relates to a gradual inflatable shoulder joint brace realizing self-control. The brace comprises an arm locating mechanism and a trunk connecting mechanism, and an axillary air bag is arranged between the arm locating mechanism and the trunk connecting mechanism. The brace is characterized in that one end of the axillary air bag is a large-head end, the other end is a small-head end, and the small-head end of the axillary air bag is located above the large-head end when the axillary air bag is located under the human axilla; an inflation-deflation mechanism located at the front end of the arm locating mechanism and capable of allowing a user to control inflation and deflation autonomously is arranged on the arm locating mechanism and is connected with the axillary air bag, and the axillary air bag can drive the arm located on the arm locating mechanism to uplift towards the human front side or return downwards during inflation or deflation. The brace has the advantages that the design is reasonable, and outward extension, outward rotation and forward bending angles of the shoulder joint can be changed flexibly.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a self-controlled progressively inflatable shoulder joint brace. Background technique [0002] At present, the shoulder joint braces in the medical market do not meet the characteristics of the dynamic changes in biology and biomechanics in the shoulder joint function damage, repair and healing process. It has the following disadvantages: 1. It is single-angle and single-height, and cannot change shoulder joint abduction, external rotation, and forward flexion angles with the healing of shoulder joint injuries, and cannot obtain moderate stress stimulation. Joint stiffness and adhesion; 2. Most of the force is passively applied, and the amount of stress applied to the joint cannot be adjusted according to the patient's pain tolerance, and it cannot be shaped and extended to increase the range of motion of the joint. [0003] In order to improve th...

It has the following disadvantages: 1. It is single-angle and single-height, and cannot change shoulder joint abduction, external rotation, and forward flexion angles with the healing of shoulder joint injuries, and cannot obtain moderate stress stimulation. Joint stiffness and adhesion; 2. Most of the force is passively applied, and the amount of stress applied to the joint cannot be adjusted according to the patient's pain tolerance, and it cannot be shaped and extended to increase the range of motion of the joint

[0004] Although the above solution solves the shortcomings of the existing technology to a certain extent, it is not conducive to the flexible change of shoulder joint abduction, external rotation, and forward flexion angle, and the overall design is not reasonable enough.
