Anti-splashing intelligent suction device for tube drawing and using method thereof

Abstract

The invention relates to an anti-splashing intelligent suction device for tube drawing and a using method thereof. The device comprises a piezoelectric film sensor, a breathing filter, an instrument amplifier, a single chip microcomputer, a relay and an aspirator, wherein the piezoelectric film sensor is installed between filter cotton and a far-end interface; the filter cotton is arranged in thebreathing filter; the piezoelectric film sensor is connected with a piezoelectric film sensor joint on a filter layer lower cover through a piezoelectric film sensor plug, then is connected to a wire,and extends out of the breathing filter to be connected with the instrument amplifier; the instrument amplifier is connected with the single-chip microcomputer through a wire, the single chip microcomputer is connected with the relay through a wire, and the relay is connected with the aspirator through a wire, and the breathing filter is connected with the aspirator through a near-end interface of a gas pipeline. Compared with a traditional tracheal tube, a set of devices is formed by the piezoelectric film sensor, the single chip microcomputer and the like, and the anti-splashing effect is higher. The device can prevent droplets from splashing through intelligent suction when the tracheal tube is pulled out.

Description

technical field [0001] The invention belongs to the field of medical aids, and in particular relates to an intelligent suction device for extubation and anti-splashing and a use method thereof. Background technique [0002] When the traditional endotracheal tube is extubated and suctioned through the endotracheal tube, due to airway irritation, a large amount of secretions, blood, or droplets or aerosols may be sprayed, especially for patients with diseases transmitted through the respiratory tract, such as new coronary pneumonia. Endotracheal tube extubation or sputum suction for patients with viral pneumonia is a medically high-risk operation because the operator is very close to the patient's head and face. When the endotracheal tube is extubated, the endotracheal tube needs to be disconnected from the breathing circuit, and then a sputum suction tube is inserted to carry out sputum suction in the catheter. Sputum suction often causes the patient to cough, resulting in th...

Problems solved by technology

When the endotracheal tube is extubated, the endotracheal tube needs to be disconnected from the breathing circuit, and then a sputum suction tube is inserted to carry out sputum suction in the catheter. Sputum suction often causes the patient to cough, resulting in the generation of respiratory droplets, aerosols or The secretion is splashed out through the endotracheal tube, which is likely to cause cross-infection of medical workers and other patients
