Special breathing machine for accurately controlling pressure of artificial airway airbag based on breathing machine waveform

Abstract

The invention discloses a special breathing machine for accurately controlling pressure of an artificial airway airbag based on breathing machine waveform. A main body is a breathing machine body. The front end of an air supply pipe of the breathing machine body is provided with an artificial airway airbag, the artificial airway airbag of the air supply pipe is fixedly connected with an air supply device, the breathing machine body is electrically connected with the air supply device through a USB wire, and the breathing machine body is provided with a power button for controlling the air supply device. The special breathing machine has the advantages that the special breathing machine is low in cost and convenient and swift to install, monitors pressure of the special breathing machine from time to time and reduces airbag oedema caused by too high airbag pressure under the conditions that the airbag pressure is lowest; when air leakage waveform occurs, pressure of the artificial airway airbag can be controlled timely through the air supply device, working efficiency and safety are improved, an alarm can be given timely, and nurses are reminded to perform correlated operations.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a special ventilator for precisely controlling the pressure of an artificial airway airbag based on the waveform of the ventilator. Background technique [0002] The ventilator is a necessary medical device for rescuing patients with respiratory failure and treating respiratory diseases. It can be achieved through tracheal intubation-style invasive ventilation. The main ventilation modes include volume-controlled ventilation mode and pressure-controlled ventilation mode. The "Mechanical Ventilation Guidelines" of the Critical Care Medicine Branch of the Chinese Medical Association recommends measuring the pressure of the air bag 3 times a day to keep the pressure in the air bag of the artificial airway at 25-30 cmH 2 O; However, we have found in clinical practice that even if the pressure in the airbag of the artificial airway is maintained at 25-30cmH 2 O, there are also a ...

The "Mechanical Ventilation Guidelines" of the Critical Care Medicine Branch of the Chinese Medical Association recommends measuring the pressure of the air bag 3 times a day to keep the pressure in the air bag of the artificial airway at 25-30 cmH 2 O; However, we have found in clinical practice that even if the pressure in the airbag of the artificial airway is maintained at 25-30cmH 2 O, there are also a small number of patients with air leak waveforms. Maybe the air bag of the tracheal intubation does not match the airway of the patient; at the same time, the patient's body position will also cause the air bag pressure of the artificial airway to be too high or too low; inevitable problem

Leakage may lead to insufficient ventilation of the patient, reduce ventilation tolerance, seriously affect the ventilation effect, and may even threaten life
