Abstract

The invention relates to a device for uniformly mixing anesthetic gas and detecting the concentration of the anesthetic gas. The device comprises a buffer mixing device and a detection device; the buffer mixing device is connected with the detection device through an air channel, the buffer mixing device is used for receiving anesthetic gas in the anesthesia machine and mixing the anesthetic gas,and the detection device is used for detecting the concentration of the anesthetic mixed gas coming out of a first anesthetic mixed gas outlet. Compared with the prior art, the gas contact area is increased through the spiral bent pipe, anesthetic gas is further mixed evenly through the convection principle, and the anesthetic drug concentration detection precision is improved. Gas is uniformly mixed by arranging a pure mechanical structure with two gas paths, extra energy does not need to be provided, energy consumption is reduced, and practicability is achieved.

Description

technical field [0001] The invention relates to an anesthetic gas mixing device for an anesthesia machine, in particular to a device for mixing the anesthesia gas and detecting the concentration of the anesthesia gas. Background technique [0002] The anesthesia machine is a very important device in clinical anesthesiology at present, and it is used for general anesthesia, oxygen supply, assisted or controlled breathing and other surgical operations. The anesthesia vaporizer is a key component of the anesthesia machine. Due to the use of powerful inhalation anesthetics, its quality not only marks the level of the anesthesia machine, but also relates to the success or failure of inhalation anesthesia, which directly affects the safety of patients. The detection and control of the concentration of anesthetic drugs is also a topic that clinicians and medical engineers have been paying attention to and studying. [0003] The key component that affects the concentration of anes...
