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

[0061] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] Such as figure 1 as shown, figure 1 It is a flow chart of the calculation method of the anesthetic dosage of the anesthesia machine in an embodiment of the present invention. The calculation method of the anesthetic dosage of the anesthesia machine mentioned in this embodiment includes:

[0063] Step S10, the monitoring device measures the concentration of the anesthetic gas and the flow rate of the mixed gas, and the main controller records the measurement time;

[0064] Step S20, the main controller calculates the gaseous anesthetic dosage Q according to the concentration of the anesthetic gas, the flow rate of the mixed gas and the measurement time 气 ;

[0065] In this embodiment, the gaseous anesthetic dosage Q 气 Usually related to the concentration of anesthesia gas and the flow rate of the mixed gas, ...

Abstract

The invention discloses an anesthetic dosage calculation method and an anesthetic dosage calculation system for an anesthesia machine. The method includes steps: using a monitoring device to measure anesthetic gas concentration and mixed gas flow, and using a main controller to record measuring time; using the main controller to calculate gaseous anesthetic dosage Q according to the anesthetic gas concentration, the mixed gas flow and the measuring time; and using the monitoring device to identify anesthetic gas types, and using the main controller to calculate liquid anesthetic dosage Q corresponding to the gaseous anesthetic dosage Q according to a gas molar volume calculation method. Errors caused by manual calculation can be avoided, accuracy and precision of anesthetic dosage calculation results can be improved effectively, and basis is provided for patient safety guaranteeing, operation costing and medical insurance claim.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a method and system 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. ...
