a co 2 Remote management non-invasive ventilator with monitoring function and its working method

Abstract

The invention discloses a remote management non-invasive breathing machine with a CO2 monitoring function and a working method thereof. The remote management non-invasive breathing machine comprises abreathing facial mask, a pressure measuring pipe, a mainstream-type PETCO2 monitor and a breathing machine main unit; the breathing facial mask is connected with the breathing machine main unit, oneend of the pressure measuring pipe is connected with a connecting pipeline, and the other end of the pressure measuring pipe is connected with the breathing machine main unit; the mainstream-type PETCO2 monitor is connected to the connecting pipeline of the breathing facial mask and the breathing machine main unit through a pipeline adapter, the mainstream-type PETCO2 monitor starts to monitor PETCO2 data after receiving a monitoring instruction sent by the breathing machine main unit, and sends a monitoring signal to the breathing machine main unit, and after the breathing machine main unit receives the monitoring signal, the ventilation mode and the breathing pressure are adjusted; after finishing monitoring, the mainstream-type PETCO2 monitor sends the monitored data and a monitoring finishing signal to the breathing machine main unit, and after receiving the monitored data and the monitoring finishing signal, the breathing machine main unit restores the ventilation mode and the breathing pressure to modes and parameters before monitoring, and continues to ventilate the breathing facial mask.

Description

technical field [0001] The invention relates to a medical ventilator, in particular to a ventilator with CO 2 Remote management of non-invasive ventilators with monitoring functions and their working methods. Background technique [0002] end-tidal CO 2 Monitoring is a clinically very important parameter, normal end-tidal CO 2 The concentration is about 5%, which is PETCO 2 About 38mmHg (5Kpa). PETCO 2 It is closely related to the change of the patient's ventilation function. If PETCO 2 A gradual increase indicates that the patient is hypoventilated. Most of the reasons are because the tidal volume setting is too small or the circuit leaks. If PETCO 2 A gradual decrease indicates that the patient may be hyperventilated. Therefore, PETCO 2 The waveform can well reflect the patient's ventilation status, and has high clinical auxiliary diagnostic value. When a patient needs a ventilator due to their condition, PETCO 2 The value can be used as the basis for adjustin...

Problems solved by technology

Mainstream CO 2 When the monitor is used with a ventilator, due to the flushing effect of the ventilator, the measured CO 2 Biased data is inaccurate; side-flow CO 2 The monitor is inconvenient to carry due to the large size of the equipment, and because the traditional side-flow CO on the market 2 The length of the monitor duct is long, so it is impossible to monitor CO in real time. 2 , so that the obtained data has a hysteresis, so the data is also inaccurate

Therefore, it is difficult for the patient to communicate with the end-tidal CO when using the ventilator. 2 The monitor cooperates very well, making it impossible for the patient to simultaneously monitor CO while using the ventilator. 2 the goal of
