Abstract

The invention discloses a control method of a pulse breathing module for a breathing machine, and relates to an improvement of the control method of the pulse breathing module for the breathing machine. The control method of the pulse breathing module for the breathing machine is as follows: when continuous oxygen supply is needed, the control mode is as follows: an oxygen gas source enters from agas inlet, passes through a valve interface F of a continuous flow control valve and a valve interface G of a pulse flow control valve, and passes through a middle branching point M to be divided into two paths, and the upper path passes through a valve interface C of a respiration detection valve and a valve interface B of the respiration detection valve, then enters an air inlet of a flow and oxygen concentration sensor and an air outlet end of a flow and oxygen concentration sensor and then reaches an air outlet; and the lower path passing through the middle branching point M passes through a valve interface D of the continuous flow control valve, and passes through the flow and oxygen concentration sensor to detect the oxygen concentration. The method overcomes the defect that existing pulse breathing control methods are prone to generating unstable air flow in the using process, eliminates potential safety hazards caused by the unstable air flow, and can conveniently perform switching between oxygen supply and normal air supply.

Description

technical field [0001] The invention relates to an improvement of a control method of an oxygen supply device for a ventilator, in particular to an improvement of a control method of a pulse breathing module for a ventilator. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. The pulse breathing (oxygen supply) devices of ventilators that are common in the market at present, these pulse breathing devices are prone to oxygen leakage defects; the finished gas that is mi...
