Abstract

The invention relates to a ceramic rotary valve for an anaesthetic evaporator. A valve body of the rotary valve is made of a ceramic material. The invention also provides the anaesthetic evaporator comprising the ceramic rotary valve and an anaesthesia machine comprising the anaesthetic evaporator. In addition, the invention also provides a method for controlling the concentration of anaesthetic output by the anaesthetic evaporator by using the anaesthetic evaporator comprising the ceramic rotary valve.

Description

technical field [0001] The present invention relates to anesthesia vaporizers, and more particularly, the present invention relates to rotary valves for use in anesthesia vaporizers. Background technique [0002] An anesthesia machine is a medical device commonly used in clinical operations. It is used to deliver anesthetics into the patient's body through a mechanical circuit, and finally anesthetize the patient. It mainly includes gas supply and delivery systems, anesthesia vaporizers, ventilators, monitoring and control components of the system, etc. As a key component of the anesthesia machine, the evaporator is used to turn the anesthetic agent into a vapor, and use a certain amount of carrier gas to obtain an anesthetic gas with a certain concentration. Valves, such as rotary valves, are often used in vaporizers to control the concentration of anesthetic agent output therefrom.
