Abstract

The invention discloses a noninvasive ventilator control system, and particularly relates to the technical field of ventilators. An airflow generator is located in the ventilator and can provide sufficient flow and pressure ranges, an expiration control valve can control gas conveying and conveying paths in the ventilator, a microprocessor receives data of the two actuators and controls the two actuators through an algorithm, and the airflow generator is connected with the expiration control valve. The airflow generator further directly controls the flow of gas conveyed to a patient and the pressure of gas passing through a main flow path, the expiration control valve is an electric proportional valve, and the output end of the expiration control valve is connected with a breathing flow control valve. When the ventilator provides expiration airflow for a patient, the airflow flow is appropriate, the pressure is moderate, the use experience of a user is improved, the problems that the airflow pressure and flow are too large and too small are solved, and stable supply of the airflow can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of ventilator, more specifically, the present invention relates to a non-invasive ventilator control system. Background technique [0002] With the continuous development of medical device technology, users have higher and higher requirements for the intelligence of medical devices. Among them, non-invasive ventilator, as a common medical device, has been used in various departments of the hospital, such as respiratory department, emergency department, pediatrics, internal medicine such as cardiology, anesthesiology, surgery, surgical intensive care unit, intensive care unit, critical care medicine Departments, burn departments, etc., and patients' families are widely used. However, during the use of the existing ventilator, the control of the airflow is unstable, so it is difficult to achieve a satisfactory effect. Contents of the invention [0003] In order to overcome the above-mentioned defec...
