Rehabilitation robot multifunctional torque sensing arm rehabilitation device

Abstract

The invention discloses a multifunctional torque sensing arm rehabilitation device for a rehabilitation robot. The arm rehabilitation device comprises a left movable arm, a right movable arm, a semilunar bracket, a torque measuring mechanism, a left pressure measuring mechanism and a right pressure measuring mechanism, wherein the left and right movable arms are rotationally connected with two ends of the semilunar bracket; the semilunar bracket comprises a bent beam and a straight beam; the bent beam is provided with a left movable arm positioning hole and a right movable arm positioning hole; the left and right movable arms are provided with left and right movable arm fixing holes; the torque measuring mechanism comprises a concentric ring and left and right center beams; the left end of the left center beam is connected with the semilunar bracket, and the right end of the left center beam is connected with the concentric ring; two sides of the left center beam are provided with a front left strain gage and a rear left strain gage; the left end of the right center beam is connected with the concentric ring, and the right end of the right center beam is connected with the semilunar bracket; two sides of the right center beam are provided with a front right strain gage and a rear right strain gage; the left and right pressure measuring mechanisms are one-dimensional pressure measuring devices; and each one-dimensional pressure measuring device consists of a one-dimensional pressure sensor and a tray.

Description

technical field [0001] The invention belongs to the field of rehabilitation medical equipment, and is an arm rehabilitation device for helping patients to realize rehabilitation training. It is mainly used to be installed at the end of the output shaft of a rehabilitation training robot with a rotating shaft output, so as to realize arm training for patients with impaired arm function. Background technique [0002] Stroke is a common and frequently-occurring disease among middle-aged and elderly people. Generally speaking, it is easier for stroke patients to recover their lower limbs than their upper limbs, especially the hand, elbow and wrist. Rehabilitation medicine experts pointed out that the earlier rehabilitation training can reduce the disability rate and improve the probability and effect of functional recovery. Most clinical rehabilitation methods for stroke patients rely on the one-on-one physical therapy provided by the therapist to the patient. The effect is not...
