Background
When the anesthesia machine is mechanically ventilated, a mode of a closed circulation mode is adopted, and the expired air (the mixed gas containing carbon dioxide, mainly oxygen or the anesthetic gas) in the breathing pipeline of the anesthesia machine is absorbed by the carbon dioxide absorption tank and then enters the breathing circuit again for use. The carbon dioxide absorption tank has the effect principle that the carbon dioxide absorbent filled in the carbon dioxide absorption tank reacts with carbon dioxide chemically, so that the carbon dioxide is absorbed. When the carbon dioxide absorbing tank is used for absorbing the gas exhaled from the breathing pipeline of the anesthesia machine, the gas exhaled from the breathing pipeline of the anesthesia machine enters the carbon dioxide absorbing tank through the gas inlet pipe, and the gas absorbed by the carbon dioxide absorbing tank returns to the breathing pipeline of the anesthesia machine again through the gas outlet pipe.
At present, all carbon dioxide absorption tanks of anesthesia machine manufacturers are designed in the middle section of a breathing pipeline of the anesthesia machine and are collectively called as built-in carbon dioxide absorption tanks, but the built-in carbon dioxide absorption tanks are required to be matched with built-in carbon dioxide primary tank openings of various anesthesia machines, and the research and development cost is extremely high.
