Anaesthesia machine gas path system and ventilation method thereof

Abstract

In order to solve the problems that an existing anesthesia machine is large in oxygen consumption and limited in use scene, the invention provides an anesthesia machine gas path system which comprises an oxygen supply module, a laughing gas supply module, an air supply module, a driving gas switching valve, a breathing gas mixing module, a breathing end module and a driving end module. The driving end module is used for providing gas suction pressure of the breathing end, the oxygen supply module is provided with a first oxygen flow division and a second oxygen flow division, the air supply module is provided with a first air flow division and a second air flow division, the first oxygen flow division and the first air flow division are communicated with the driving gas switching valve, and the driving gas switching valve is communicated with the driving end module. And the driving gas switching valve is conducted to the driving end module. Meanwhile, the invention further discloses a ventilation method of the anaesthesia machine air path system. According to the anesthesia machine gas path system, oxygen consumption can be reduced to a certain extent, pressure limitation on an oxygen source is reduced, and the stability of an anesthesia machine system is improved.

Description

technical field [0001] The invention belongs to the technical field of inhalation anesthesia equipment, and in particular relates to a ventilation method for an air circuit system of an anesthesia machine. Background technique [0002] The so-called anesthesia refers to the temporary loss of consciousness in all or part of the organism for surgical treatment. There are various methods of anesthesia, such as acupuncture anesthesia, injection anesthesia and inhalation anesthesia. At present, the method of general anesthesia used in hospitals is still mainly inhalation anesthesia. Inhalation anesthesia has been perfected since 1846, when Browning first applied ether anesthesia. The development of modern pharmacology, the progress of science and technology, especially the application of computer technology, have greatly improved the level of modern inhalation anesthesia. Inhalation anesthesia is easy to control, safe and effective. It is the first choice for surgery in the c...
