T/SRMA 28-2023 Flexible Pneumatic Finger Passive Trainer General Technical Requirements

Scope

Scope: This document specifies the classification, requirements, and test methods for passive trainers for flexible pneumatic fingers. This document is applicable to flexible pneumatic finger passive trainers (hereinafter referred to as trainers) used by patients with hand dysfunction caused by diseases such as stroke, hand trauma, brain injury, spinal cord injury, orthopedic surgery, and cerebral palsy. Main technical content: The human hand is characterized by its delicate structure and flexible movements, enabling it to perform important daily activities such as grasping, holding, and pinching. Loss of finger movement function can place a heavy burden on patients and their families, making research on finger rehabilitation of great significance. There is an important theory in rehabilitation therapy - the continuous passive movement theory, which states that continuous passive movement can accelerate the healing and regeneration of joint cartilage and surrounding tendons and ligaments. Based on this theory, the traditional method of finger rehabilitation involves physicians guiding patients to perform rehabilitation exercises for a long time. However, compared with the large number of patients with motor disorders, there is a shortage of rehabilitation physicians. This article proposes a pneumatic training glove that uses repeated inflation and deflation to drive the bionic muscles on the pneumatic glove to expand and contract, thereby driving the pneumatic glove to guide the fingers to perform flexion/extension movements, promoting blood circulation in the upper limbs, relieving muscle tension or edema, and improving symptoms such as finger spasm and paralysis.
