Abstract

The invention relates to a pressure maintaining device of a ventilator. The device comprises an oxygen source, a compressed air source and an air-oxygen mixer; an oxygen flow control valve is connected between the oxygen source and the air-oxygen mixer through a communication pipeline, and the oxygen flow control valve is used for controlling the oxygen flow in the ventilator pressure maintainingdevice under the action of an oxygen flow control signal ueo; and an air flow control valve is connected between the compressed air source and the air-oxygen mixer through a communication pipeline, the air flow control valve is used for controlling the air flow in the ventilator pressure maintaining device under the action of an air flow control signal uea, and the ventilator pressure maintainingdevice can guarantee synchronous adjustment of pressure and oxygen concentration, so that the clinical use effect of the ventilator is guaranteed.

Description

technical field [0001] The present application relates to the technical field of medical equipment control, in particular to a ventilator pressure maintaining device. Background technique [0002] For ventilators, the accuracy and stability of oxygen concentration and pressure maintenance are the core and most basic requirements. Oxygen concentration and pressure maintenance have different goals in the two processes, and both need to control the flow of air and oxygen. Therefore, if the controller is not stable enough or the performance of the device changes after long-term use, it will affect the clinical use of the ventilator. [0003] At present, the pressure and oxygen concentration maintenance of ventilators are usually designed separately. The pressure during the process of maintaining the oxygen concentration may not meet the usage requirements. Although the relevant design can maintain the pressure of the breathing process, the synchronous adjustment of the oxygen...
