Ventilation therapy device and control method

Abstract

The present invention provides a ventilation treatment device and a control method, including: a device body, a breathing circuit, and a patient interface. The acquisition module obtains the target pressure value of the patient interface; the calculation module calculates the actual pressure value of the patient interface according to the pressure value and flow value of the signal collection point; the first control module adjusts the pressure value according to the actual pressure value and the target pressure value. The output flow of the device body. The present invention determines the actual pressure value of the patient interface through the feedback of the output parameters of the signal collection points in the device body, and determines the breathing state of the patient according to the comparison between the actual pressure value and the target pressure value, and outputs the airflow corresponding to the threshold value, so that the patient The air pressure of the received airflow reaches the range of the expected target pressure value to achieve the therapeutic effect.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a ventilation treatment equipment and a control method. Background technique [0002] In modern clinical medicine, ventilation treatment equipment occupies a very important position in the field of modern medicine. Ventilation treatment equipment is a vital medical treatment that can prevent and treat respiratory failure, reduce complications, and save and prolong patients’ lives. The device can mix pure oxygen with air and provide it to the patient. [0003] The treatment mode of the traditional ventilation treatment equipment is to form a closed air path between the patient and the ventilation treatment equipment, that is, form a sealed state with the patient’s facial area through the patient interface (usually a ventilation mask), and the patient’s exhaled air passes through a specific air path or The specially designed exhaust hole discharges, so that the patient's exhaust channel ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a ventilation therapy device and a control method to solve the problem that the ventilation therapy device in the prior art cannot monitor the pressure at the end of the air flow in a semi-open air circuit, so that it cannot realize the control of the pressure at the end of the air circuit
