Oxygen cell holder component, oxygen cell component and anesthesia machine

Abstract

The invention discloses an oxygen cell holder component, an oxygen cell component and an anesthesia machine. The oxygen cell holder component comprises an oxygen cell holder and a control valve; the oxygen cell holder is provided with a run-through gas channel; the gas channel is provided with a valve port for allowing gas in a respiratory system circuit to flow into the gas channel; the control valve is provided with a degree of freedom relative to the linear motion of the oxygen cell holder; the control valve is provide with a closing position and an opening position on the motion track thereof; and when an oxygen cell unit departs from the gas channel, the control valve automatically resets to the closing position and closes the valve port. The oxygen cell holder component can automatically close the valve port whenever the oxygen cell unit is pulled up, so that gas leakage is avoided, the operation is convenient, and the risk of gas leakage due to plug loss is eliminated.

Description

technical field [0001] The invention relates to the field of anesthesia machines, in particular to an oxygen battery assembly used in the air circuit of the breathing system of the anesthesia machine. Background technique [0002] The oxygen cell is a sensor used to detect the oxygen concentration of fresh gas in the anesthesia machine, which is installed in the installation hole of the air circuit of the breathing system of the anesthesia machine. Since the oxygen cell needs to be calibrated every day, the oxygen cell needs to be placed in the air with an oxygen concentration of 21% during calibration. At this time, the installation hole needs to be sealed to avoid the leakage of gas in the air circuit of the respiratory system and ensure the air circuit of the respiratory system. normal ventilation. [0003] One existing technical solution is that there is no plug at the installation hole, and after the oxygen battery is unplugged, the gas path of the respiratory system i...

AI Technical Summary

Problems solved by technology

Therefore, it is generally necessary to complete the oxygen cell calibration before the airway ventilation of the respiratory system, which brings inconvenience to the operation

If the oxygen cell calibration is unplugged during the airway ventilation of the respiratory system, the normal ventilation of the airway of the respiratory system cannot be guaranteed, and it will cause leakage of anesthesia gas, pollute the air and is not environmentally friendly

[0004] Another existing technical solution is to set an independent plug in the installation hole, and block the installation hole after the oxygen battery is unplugged, so as to ensure the normal ventilation of the air circuit of the respiratory system, but this operation is cumbersome and must be managed well Plug to prevent loss
