Problems solved by technology

[0003] However, when the patient’s wrist is injured and unable to use force, the crutches cannot be used to walk together, and the medical crutches cannot be used. Moreover, some patients are relatively weak after the operation. To lift the crutches by holding the handle (forearm and rear arm straight), it is necessary The strength of the shoulder muscles is used, and the strength of the shoulder muscles of ordinary people (compared to the large muscle groups such as the pectoralis and back muscles) is relatively small. It is difficult to effectively control the crutches. In addition, the wrist grasps the grip bar. The grip bar is used as the force application end of the arm. increase, resulting in increased difficulty in wrist grasping of crutches

Abstract

The invention discloses an axillary crutch, and belongs to the field of crutches. The axillary crutch comprises a crutch body, wherein the crutch body comprises a bracket, a support rod, a holding rodand a dragging pad; the dragging pad, the bracket and the support rod are fixedly connected in sequence from top to bottom, and the holding rod is rotatably connected to the inner end of the bracket;an arm sleeve is arranged on the inner side of the bracket and located on the upper side of the holding rod, a connecting mechanism is connected between the arm sleeve and the crutch body, positioning holes are uniformly formed in the two outer side walls of the crutch body, and according to the crutch, when the wrist of a patient is injured, the middle connecting assembly can be detached from the crutch body; the arm sleeve is adjusted to be horizontal, the arm sleeve is connected with the crutch body through the middle connecting assembly, the arm stretches into the arm sleeve, the arm sleeve and the crutch body are perpendicularly distributed at the moment, arm strength can be used for lifting the crutch body, the wrist does not need to be used, and secondary injury of the wrist is avoided.

Description

technical field [0001] The invention relates to the field of crutches, in particular to an underarm crutch.
