Wrist training device driven by connecting rod reciprocating mechanism

Abstract

The invention relates to a wrist training device driven by a connecting rod reciprocating mechanism. The wrist training device contains a turnover mechanism, the connecting rod reciprocating mechanismand a power mechanism, wherein the turnover mechanism realizes turning over and pitching actions of palm boards through transmission of a cylindrical cam and gears, so that when hands of a patient are fixed on the palm boards, the palms of the patients can be driven to perform training of turning over and pitching actions; in order to realize repeated movement of the actions, the turnover mechanism is driven by the connecting rod reciprocating mechanism to realize repeated operation of the actions; and a cone gearbox in the power mechanism can realize stepless speed adjustment of driving speed, so that requirements for different turning over speed situations can be met. The training device can replace rehabilitation and nursing personnel to perform targeted training of the turning over and pitching actions of wrist joints on the patient, and can assist the patients to rehabilitate the functions of the wrist joints as soon as possible.

Description

Technical field [0001] The invention relates to the technical field of rehabilitation training equipment, in particular to a wrist training device driven by a connecting rod reciprocating mechanism. Background technique [0002] The rehabilitation of patients with hemiplegia, stroke or cerebral palsy and certain burn patients with central nervous system dyskinesia has become a major social problem. According to the developmental characteristics of the human body, the rehabilitation of the nerves and muscles of the extremities is the slowest. Therefore, the rehabilitation process For example, the rehabilitation of the wrist joints is the most critical. In the clinical treatment process, the movement of the end joints is often affected by the proximal muscles, and the movement of the limbs mainly depends on the contraction of the proximal muscles. , So that the muscles that control the end joints cannot be trained. The traditional rehabilitation treatment methods are mainly one-on-...

[0002] The rehabilitation of patients with hemiplegia, stroke or cerebral palsy, and patients with central nervous movement disorders caused by some burn patients has become a major social problem. According to the development characteristics of the human body, the recovery of the nerves and muscles at the end of the limbs is the slowest. Therefore, the rehabilitation process Among them, the rehabilitation treatment of the extremity joints such as the wrist joint is the most critical. In addition, in the clinical treatment process, the movement of the terminal joints is often affected by the muscles at the proximal end of the body, and the movement of the limbs also mainly depends on the contraction of the muscles at the proximal end of the body. , so that the muscles that control the terminal joints cannot be trained. The traditional rehabilitation tre
