Assistant rehabilitation soft hand

Abstract

The invention provides an assistant rehabilitation soft hand comprising five soft copying fingers corresponding to human fingers. Each copying finger includes a finger body, protrusion segments and straight segments, multiple protrusion segments and multiple straight segments are arranged at intervals in the length direction of the finger bodies, and are located at the finger back side of the finger bodies; multiple protrusion segments correspond to joint parts of the human fingers, and the straight segments correspond to non-bending segments of the human fingers; each finger body is internally provided with a runner in the length direction of the finger body, and each runner has a slender hole structure; an expansion chamber is arranged inside each protrusion segment, and each expansion chamber communicates with the corresponding runner. The rehabilitation hand is prepared by processing a silicone rubber material and driven by gas or liquids. The structure completely imitates the design of the hand structure, can bend only at joints and cannot bend at non-joints, can be better attached to the human hand and is more suitable for rehabilitation application.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to an auxiliary rehabilitation software hand. Background technique [0002] For paralyzed patients such as cerebral apoplexy and cerebral congestion, rehabilitation therapy is a key and effective treatment method for them to regain hope in life. However, the traditional rehabilitation equipment, especially the rehabilitation equipment for the hand, has disadvantages such as complex structure, less degrees of freedom, less movement patterns, and weak adaptability and flexibility, and most of them use rigid structures, and there are two insurmountable problems. Disadvantages: 1) The rigid structure is easy to cause secondary injury to the patient during the auxiliary treatment process, which not only cannot help the patient's recovery, but also aggravates the patient's condition; 2) The rigid structure has a single movement pattern and is difficult to fit with the human hand , which ca...

AI Technical Summary

Problems solved by technology

However, traditional rehabilitation equipment, especially for hand rehabilitation equipment, has disadvantages such as complex structure, less degrees of freedom, few movement modes, weak adaptability and flexibility, and more rigid structures, there are two problems that cannot be overcome. Disadvantages: 1) The rigid structure is easy to cause secondary injury to the patient in the process of adjuvant therapy, which not only cannot help the patient recover, but also aggravates the patient's condition; 2) The rigid structure has a single movement mode, which is difficult to fit with human hands , cannot simulate the movement of the human hand very well

Although the soft hand driven by steel wire has a certain degree of flexibility, the steel wire will still cause harm to the patient. Although the soft rehabilitation hand based on the fiber-reinforced driver is made of silicone rubber soft material, the entire structure will bend after inflation and cannot be well attached to the human hand. , thus causing discomfort to the patient
