Problems solved by technology

When performing calibration and calibration of this type of oxygen cell, the current operation method is to take the oxygen cell out of the absorption circuit and expose it to a calibration gas with an oxygen content of about 21%, which is time-consuming and will increase the workload of medical staff. Labor intensity
In addition, with the above-mentioned installation method, the oxygen battery and its cables need to be disassembled when the absorption circuit is sterilized under high temperature and high pressure. In the case of complicated pipelines in the operating room, one more cable will increase the cost for the doctor. One trouble, even one more risk

Abstract

The invention provides an anesthesia machine, an oxygen concentration monitoring method and an oxygen concentration monitoring device thereof. The oxygen concentration monitoring device comprises an installation seat, which is equipped with a loop gas inlet, a calibration gas inlet and a gas outlet; a switching element, which is arranged on the installation seat and is switched between communicating the loop gas inlet with the gas outlet and communicating the calibration gas inlet and the gas outlet; an oxygen sensor, which is arranged on the installation seat to monitor the oxygen concentration of gas flowing through the oxygen concentration monitoring device; and an air pump, which is arranged on the installation seat and is equipped with an air pump inlet communicated with the gas outlet and an exhaust gas outlet. Thus, according to the oxygen concentration monitoring device provided by the invention, automatic scaling calibration of the oxygen sensor can be achieved, and disassembly of the oxygen sensor is unnecessary, thus greatly saving time and reducing the labor intensity of workers.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anesthesia machine, an oxygen concentration monitoring method and an oxygen concentration monitoring device. Background technique [0002] In recent years, the oxygen sensors used in anesthesia machines, also known as oxygen batteries, can be roughly divided into two types in principle, electrochemical oxygen batteries and transient magnetic oxygen sensors. [0003] The electrochemical oxygen cell is used to measure the oxygen concentration in the mixed gas of the anesthesia machine through the chemical principle. Under the condition of constant working pressure and constant temperature, the voltage value generated by the oxygen cell is proportional to the oxygen concentration. The output voltage of each oxygen cell is in It is basically stable throughout the lifetime. However, if the electrochemical oxygen cell continues to be used after reaching its service life, ...
