AI Technical Summary

Technical Problem

Current cold stimulation therapy lacks an effective detection and response mechanism to determine whether swallowing actions have been successfully induced, and poses risks of suffocation and respiratory safety issues in enclosed spaces.

Method used

A cold stimulation device for the rehabilitation of swallowing disorders was designed. It automatically triggers oral cavity sealing by biting action, detects swallowing action by detecting changes in negative pressure in the detection tube, and controls stimulation by using a delayed start switch. Combined with biting airbag and sealing plate, it realizes the closure and opening of the oral cavity to ensure breathing safety.

Benefits of technology

It achieves accurate detection and response to swallowing movements, ensuring that the timing and rhythm of each stimulus meet physiological needs, preventing the risk of suffocation, ensuring the patient's respiratory safety, and realizing the automation and safety of swallowing rehabilitation training.

Abstract

The invention belongs to the technical field of dysphagia rehabilitation, and particularly relates to a cold stimulation device for dysphagia rehabilitation, which comprises a support column, one end of the support column is coaxially and fixedly connected with a reciprocating electric telescopic rod, the telescopic end of the reciprocating electric telescopic rod is fixedly connected with a semiconductor touch head, the support column is fixedly connected with an occlusion seat, and the occlusion seat is fixedly connected with a rotary shaft. Occlusion air bags are symmetrically and fixedly connected to the occlusion seat, the occlusion air bags are communicated with the supporting column, and a detection tube is fixedly connected to the occlusion seat; by means of an oral cavity sealing mechanism automatically triggered by the occlusion action, the swallowing action can be accurately detected according to the oral cavity negative pressure, stimulation can be paused through the delay starting switch after the effective swallowing action is detected, the next round of training is automatically started after a rest, it is guaranteed that the time and the rhythm of each time of stimulation meet physiological response, and the training efficiency is improved. And normal expiration can be realized while an oral cavity closed space is formed, so that the breathing safety is guaranteed.
