Ventilation treatment device and control method

Abstract

The invention provides a ventilation treatment device and a control method. The device comprises a device body, a breathing tube and a patient interface, and the device body further comprises a signalacquisition module configured to acquire an output pressure value of a signal collection point of the device body, a target signal obtaining module for obtaining a target pressure value for a patientinterface end, a calculating module for calculating an actual pressure value of the patient interface end according to the pressure value and the flow value of the signal collection point and a firstcontrol module for adjusting output flow of the device body according to the actual pressure value and a target pressure value. The method determines the actual pressure value of the patient interface by feedback of the output parameter of the signal collection point in the device body, determines the breathing state of the patient according to the comparison between the actual pressure value andthe target pressure value, and outputs the airflow corresponding to a threshold value, so that the air pressure of the received airflow by the patient reaches an expected target pressure value rangeto 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 therapy equipment occupies a very important position in the field of modern medicine. Ventilation therapy equipment is a vital medical treatment that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. A device that mixes pure oxygen with air and delivers it to a patient. [0003] The treatment mode of traditional ventilation therapy equipment is to form a closed gas path between the patient and the ventilation therapy device, that is, to form a sealed state with the patient's facial area through the patient interface (usually a ventilation mask), and the exhaled gas of the patient passes through a specific gas path or The specially designed exhaust hole makes the patient's exhaust channel fixed whe...
