AI Technical Summary

Technical Problem

Traditional compression cuffs have problems in upper limb rehabilitation training, such as being cumbersome to wear, easy to get caught and shift, and low pressure control accuracy. In addition, the measurement methods are complicated and not easy to promote or have insufficient accuracy, which affects the training effect and patient comfort.

Method used

It uses an automatic retractable cuff to replace the traditional Velcro fastener, and combines a controller to automatically adjust the airbag pressure. It also integrates a probe component to monitor arterial blood flow in real time, enabling convenient single-person wear and stable and accurate blood flow restriction training.

Benefits of technology

It enables convenient single-person wearable, stable and precise blood flow restriction training, improves training effectiveness and patient comfort, ensures the stability and accuracy of pressure control, and reduces the risk of skin friction.

Abstract

The invention relates to the technical field of rehabilitation, in particular to an upper limb rehabilitation training device which comprises a cuff, an air bag is fixedly connected to the inner side of the cuff and communicated with an air pump, the two ends of the cuff are a fixed end and a movable end respectively, a box is fixedly connected to the outer side of the fixed end of the cuff, and the interior of the box is divided into a storage cavity and a control cavity through a partition plate. The side wall of the storage cavity is provided with a storage opening, the inner side wall of the storage cavity is fixedly connected with a motor, an output shaft of the motor is coaxially and fixedly connected with a reel, the side wall of the reel is fixedly connected with a connecting rod, and the movable end of the cuff is fixedly connected with the side wall of the connecting rod; a controller is arranged in the control cavity, and a probe assembly is embedded in the inner side of the cuff. A traditional magic tape is replaced by the automatic retractable cuff for fixation, the controller is matched to automatically adjust the pressure of the air bag, the probe assembly is integrated to monitor the arterial blood flow in real time, the problems that a traditional pressurizing cuff is tedious to wear, easy to hook and shift and low in pressure control precision are solved, and blood flow limitation training which is convenient to wear by a single person and stable and accurate is achieved.
