AI Technical Summary

Technical Problem

Existing joint torque measuring devices have complex structures and limited measurement areas, making them ineffective for measuring the torque of joints throughout the human body, especially hand joints.

Method used

A joint torque measuring device was designed, comprising a base, a slide rail, a force measuring unit, and a displacement measuring unit. The device measures the torque of the joint through a slider, a force sensor, and a pressing plate. Combined with a drive unit and a transmission mechanism, it achieves automated measurement and is adaptable to different joint sizes to measure the torque of various joints.

Benefits of technology

It enables torque measurement of joints in various parts of the human body, especially the joints of the upper and lower limbs and fingers, providing a basis for assessing muscle strength and motor function, supporting the formulation and adjustment of rehabilitation treatment, and improving the accuracy and automation of measurement.

Abstract

The utility model discloses a joint torque measuring device, which comprises a base provided with a slide rail and used for bearing a force measuring unit and abutting against a static limb joint of a joint to be measured; the force measuring unit is mounted on the sliding rail in a sliding manner and is used for receiving and measuring the acting force of a movable limb joint of the joint to be measured; and the displacement measuring unit is arranged on the base and is used for measuring the displacement of the force measuring unit. The device can be used for measuring torques of joints of all positions of a human body, such as joints of upper and lower limbs or fingers, the muscle strength and motion function conditions of the joints can be evaluated only by adjusting the sizes of all parts of the device to be matched with the sizes of the corresponding joints and limbs, and basis is provided for formulation and adjustment of rehabilitation treatment when the device is applied to the rehabilitation treatment; accordingly, a corresponding rehabilitation training scheme is designed, and the patient is helped to recover muscle strength and motion functions.
