Problems solved by technology

Since the concentration of anesthesia gas is affected by the gas flow rate, the actual concentration often deviates from the set concentration of the anesthesia evaporation tank during low micro-flow anesthesia, so there is often a large error in the conclusion of manual calculation

Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will be described in detail in combination with examples.

[0014] Such as figure 1 As shown, the anesthetic dosage calculation method of the anesthesia machine of the present invention comprises steps:

[0015] Step 100, measure the concentration of anesthetic gas and the flow rate of the mixed gas, and record the measurement time;

[0016] Step 200, calculating the amount of gaseous anesthetic according to the concentration of the anesthetic gas, the flow rate of the mixed gas and the measurement time;

[0017] In step 300, the type of anesthetic gas is identified, and the main controller calculates the amount of liquid anesthetic corresponding to the gaseous anesthetic dosage gas according to the gas molar volume calculation method.

[0018] Specifically, the measuring the concentration of anesthesia gas and the flow rate of mixed gas, and recording the m...

Abstract

The invention provides a narcotic dosage calculating method for an anesthetic machine. The narcotic dosage calculating method comprises steps of measuring the concentration of the narcotic gas and the mixed gas flow, and recoding the measuring time; calculating the dosage of the gas narcotic depending on the concentration of the narcotic gas, the mixed gas flow and the measuring time; and recognizing the type of the narcotic gas. A main controller can be used for calculating the dosage of a liquid narcotic corresponding to the dosage of the gas narcotic, based on a method for calculating a molar volume of gas. The narcotic dosage calculating method for an anesthetic machine is advantageous in that a large error caused by manual computation can be reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a method for calculating the dosage of anesthesia for an anesthesia machine. Background technique [0002] During the operation, in order to relieve the patient's pain, the anesthesia machine is used to send the anesthetic into the patient's alveoli, 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 anesthetic drugs used in anesthesia machines are usually divided into five types, and the anesthetic gas concentrations are set differently according to the different types of anesthetic drugs. [0003] Existing anesthesia machines and anesthesia monitors can monitor the concentration of anesthesia gas, but they do not have the function of counting the amount of anesthesia drugs and cannot provide data on the amount of anesthesia drugs....
