Biological sucker imitating artificial limb receiving chamber with open structure

Abstract

The invention provides a biological sucker imitating artificial limb receiving chamber with an open structure. The biological sucker imitating artificial limb receiving chamber is sequentially provided with flexible suckers, a transition layer and a hard chamber body from inside to outside. The transition layer is provided with multiple pore structures from the inner side to the outer side, and the hard chamber body is provided with multiple hollowed-out structures. The flexible suckers can be stably sucked on a limb in a scattered distribution mode. Densely arranged hexagonal prism protrusions are arranged on the inner surfaces of the flexible suckers, a groove is formed between every two hexagonal prism protrusions, and the sucking stability of the flexible suckers is improved. The transition layer is made of a material with moderate softness, the communicated pore structures are arranged on the transition layer from the inner side to the outer side, and vent holes are distributed in the connecting surfaces of the transition layers and the flexible suckers. The hollowed-out structures are designed on the hard chamber body according to biomechanical characteristics, the weight can be reduced, and the open structure of the whole receiving chamber is achieved. The biological sucker imitating artificial limb receiving chamber is firm and stable in sucking, good in comfort and breathability, good in adaptability, low in overall weight, simple in manufacturing process and beneficial for long-use of the disable.

Description

technical field [0001] The invention relates to a bionic sucker and an open-structure prosthetic socket, belonging to the technical field of medical rehabilitation equipment. Background technique [0002] According to the latest data, there are 85.02 million people with disabilities in my country, of which 24.72 million are physically disabled, accounting for about 30% of the total number of people with disabilities. In addition, with the further aggravation of the aging society and the frequent occurrence of modern traffic accidents, there are more and more patients with physical disabilities and limb amputations. [0003] As a functional replacement aid, prosthesis can compensate and replace part of the limb functions of the disabled as much as possible, and the socket, as the most critical component, directly affects the wearing comfort and use effect of the prosthesis. At present, the traditional socket is mainly fixed on the limb stump in two ways. The first is to fix ...

Problems solved by technology

Although the above two methods can provide relatively stable results, due to long-term friction, shear force, high temperature, airtightness and other factors caused by confined spaces, limb stumps are prone to swelling, congestion, and even eczema, chronic Phenomena such as ulcers and blisters, although the patent CN 103054663 A utilizes the wearer's own gravity and pressure changes inside the prosthetic socket to drive the airbag to complete the compression and expansion of the gas, and uses the principle of evaporative cooling to discharge the heat in the socket to the Outside the receiving cavity, but the whole is still in a confined space, the air permeability is poor, and the processing is complicated, the overall stability is not very strong, and it cannot cope with complex situations
