Working system and working method for high-frequency oscillating phlegm excretion medical care vest

Abstract

The present invention provides a working system and a working method for a high-frequency oscillating phlegm excretion medical care vest. The working system comprises a controller, a controller detecting signal input end is connected with a driving circuit detecting signal output end, a driving circuit current detecting end is connected with an alternating current power supply source, a controllerpulse pump regulating output end is connected with a pulse pump control circuit input end, a pulse pump control circuit output end is connected with a pulse pump power supply, a controller fan regulating output end is connected with a fan control circuit input end, and a fan control circuit output end is connected with a fan power supply; and a controller protection signal input end is connectedwith a protection circuit protection signal output end, a protection circuit fan detecting end is connected with the fan power supply, and a protection circuit pulse pump detecting end is connected with a pulse pump power supply. A protection circuit can better avoid an overvoltage condition occurring during the use and improves safety. At the same time, the working system controls frequency of apulse pump and a rotation speed of a fan according to different needs and improves applicable ranges.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a working system and working method for a medical nursing vest for a high-frequency oscillation sputum expectoration instrument. Background technique [0002] The high-frequency chest wall oscillation sputum expectoration instrument is composed of a pulse pump, a fan and an inflatable vest. The pulse pump and fan reciprocate at high speed to inflate and deflate the vest through the air hose connected to the inflatable vest. When the frequency reaches a certain height, the chest cavity wrapped by the vest will vibrate, similar to a slight coughing action. The high-frequency oscillating chest wall simulates the oscillating action of the chest wall caused by coughing, which relaxes and liquefies the mucus and metabolites on the surface of the expiratory mucosa, making them smaller and loose and fall off. When the sputum moves from the bronchi to the main trachea, it passes ...

AI Technical Summary

Problems solved by technology

[0003] However, the high-frequency chest wall oscillation sputum-expelling instrument currently used clinically is prone to the following technical problems during use: 1. The adjustability is small, and it cannot be adjusted according to the accumulation of sputum, and cannot be used by different patients; 2. The safety is low, and the voltage and current are not controlled. Once an overvoltage or overcurrent occurs, it will threaten the life of the patient; 3. The power supply is unstable, etc.
