Abstract

The patent application discloses a gas anesthesia system which comprises an anesthesia gas volatilization pot, wherein the anesthesia gas volatilization pot is connected to an anesthetic input pipe, and the end of the anesthetic input pipe stretching into the anesthesia gas volatilization pot is connected to a spraying nozzle; the bottom end of the anesthesia gas volatilization pot is in contact connection to an electronic balance; multiple heaters are disposed on the contact face between the electronic balance and the anesthesia gas volatilization pot; a temperature sensor and an in-pot pressure sensor are disposed in the anesthesia gas volatilization pot; a pressure sensor outside the pot and a flow rate sensor are disposed at a communicating position between the anesthesia gas volatilization pot and a breathing circuit; a micro controller and a display screen connected to the micro controller are disposed in a safety monitoring system; and the electronic balance, the heaters, the pressure sensor and the flow rate sensor are connected to a micro controller.

Description

technical field [0001] The invention relates to a medical device, in particular to a gas anesthesia system. Background technique [0002] In modern medical systems, an anesthesia machine used for patient anesthesia generally includes a gas supply delivery system for supplying oxygen and carrier gas, an anesthetic gas vaporizer connected to the gas supply delivery system through a switch valve, an anesthetic gas vaporizer and oxygen delivery system A breathing circuit connected to the system, an anesthesia ventilator connected to the breathing circuit through a switch valve, a safety monitoring system and a residual gas removal system connected to the anesthesia ventilator. [0003] Among them, the anesthesia gas vaporizer, also known as the evaporation chamber, is one of the important parts of the anesthesia machine. Its quality not only represents the overall quality level of the anesthesia machine, but also relates to the quality of the anesthesia effect, and it is directl...
