A calibration method for an oxygen sensor and a medical ventilation system are disclosed. At least two electrical signals are acquired at two time points within a preset time period, when the oxygen sensor is in a preset oxygen concentration. A response function of the oxygen sensor which corresponds to the preset oxygen concentration, is determined according to the at least two time points and the at least two electrical signals. A steady-state output value of the oxygen sensor in the preset oxygen concentration is determined, according to the response function and a characteristic curve of the oxygen sensor is determined, according to the steady-state output value of the oxygen sensor in the preset oxygen concentration. The described method reduces the time waiting for the oxygen sensor to respond, thus improving calibration efficiency, and facilitating the improvement of the oxygen concentration monitoring accuracy of a ventilation device in daily use.

Calibration method for oxygen sensor, medical ventilation system, anesthetic machine, and ventilator

An anesthesia machine exhaust emission control system detects a gas flow in a connection pipeline by an electronic flow detector and displays same by a display, and a controller controls, according to an operating state of the anesthesia machine, a switch so same turns on or turns off the connection pipeline. The method for controlling the connection exhaust emission control system comprises, directly displaying a gas flow value in the connection pipeline by the electronic flow detector, the controller and the display, so that the user can conveniently and accurately read the gas flow value in the connection pipeline. The connection pipeline is turned off when an anesthesia machine is in a standby status, thereby greatly saving exhaust gas recovery resources of a hospital.

The present invention discloses a display with a lighting device comprising a display body having a housing and a power supply panel. The lighting device mounted at the bottom of the housing comprises a transparent base having a receiving cavity and a light source body disposed within the receiving cavity and powered by a power supply. Mounted at the bottom of the display body, the lighting device has the light downwards to illuminate the whole keyboard area of the medical diagnostic device such that the structure is tight without occupying extra space, thereby no inconvenience occurs during doctors' operation. Moreover, the entire lighting device is designed in a modularized manner, and therefore it is convenient for renewal and maintenance.
