Device and method for measuring mechanical properties of ankle-foot orthosis capable of simulating body weight loading

Abstract

The invention provides a device and method for measuring mechanical properties of an ankle-foot orthosis capable of simulating weight loading, and belongs to the field of mechanical testing of the ankle-foot orthosis. The measuring device comprises a mechanical frame, a direct-connected torque transmitter disposed inside the mechanical frame, a gravity-bearing bearing, a single chip microcomputer,a transmitter, a torque sensor, a worm gear reducer, a transmission coaxial machine, a power source, a motor driver, a servo motor, a planetary reducer, a flange, a display screen, an adjustable pressure device and a pedal, wherein the display screen, the adjustable pressure device and the pedal are arranged outside the mechanical frame. The device for measuring the mechanical properties of the ankle-foot orthosis capable of simulating weight loading has simple structure design, a high detection speed, high reliability, high practicability and great application prospects.

Description

technical field [0001] The invention belongs to the field of mechanical detection of ankle-foot orthoses, and relates to a device and method for measuring mechanical properties of ankle-foot orthoses capable of simulating body weight loading. Background technique [0002] As a means of orthopedic treatment, orthotics have long been used clinically. In recent years, orthotics have been gradually used in the treatment of stroke, paraplegia, hemiplegia, and cerebral palsy due to the continuous advent of new materials and the continuous improvement of production levels. Appropriate ankle-foot orthosis can prevent and correct the deformation of the foot and ankle, and to a certain extent, it can also assist in compensating for some missing functions, limit foot drop, stabilize the supratalar joint, correct foot valgus, and stabilize the subtalar joint. [0003] In 2016, the World Health Organization reported that the incidence of stroke in my country ranks first in the world. A...

Problems solved by technology

[0004] At present, the production and clinical application of ankle-foot orthoses are only based on clinical experience and the rough measurement and feeling of medical staff. Due to individual differences such as patient weight, it takes a long time to try, adjust and correct before use to meet the needs of patients. lack of quantifiable indicators in the testing process of ankle-foot orthoses
