The invention discloses a drug dosage metering supply device for an anesthesia machine used in anesthesiology department, which comprises a sequentially connected resistance mechanism, a metering compensation mechanism and a supply tank for storing anesthetic gas; the metering compensation mechanism can store the supply tank The gas in the gas is pumped out to the anti-reverse mechanism, and the anti-reverse mechanism can prevent the gas from being sucked back into the metering compensation mechanism. The present invention can use the metering compensation mechanism to realize the action of increasing the amount of compensation during the supply process. When the patient’s inhalation of anesthetic gas is not greater than the volume A of the gas extracted in the first volumetric metering pumping, the metering compensation mechanism only starts the first volumetric metering pumping; when the patient’s inhalation of anesthetic gas is greater than the gas volume A, The metering compensation mechanism starts the second volumetric metering pumping for gas compensation.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug metering supply device and a control method for an anesthesia machine used in an anesthesiology department. Background technique [0002] The anesthesia machine sends the anesthetic into the alveoli of the patient through a mechanical circuit, forming a partial pressure of the anesthetic gas, which diffuses into the blood, and directly inhibits the central nervous system, thereby producing the effect of general anesthesia. The anesthesia machine is a semi-open anesthesia device. It is mainly composed of anesthesia evaporation tank, flow meter, folding bellows ventilator, breathing circuit, corrugated pipeline and other components. When the anesthesia machine is working, the patient can inhale the anesthetic, which is sent into the lungs of the patient in the form of steam or gas through a certain device (such as a volatilizer), enters the blood circulation through...
