Mindray SV300 Ventilator Air O2 Flow Sensor PN 840521 Medical Equipment

Medical Equipment Mindray SV300 Ventilator Air Flow Sensor O2 flow sensor PN 840521

► Brief Introduction

The connector of high-pressure O2 inlet is designed to be NIST/DISS as required by the standard to prevent misconnection. The connector of low-pressure O2 inlet is designed to be quick connector which is compatible with (CPC) PMC series and provides pneumatic cut-off function to prevent gas error between the high-pressure O2 and low-pressure O2 inside the ventilator. Air passes through the dust filter and HEPA filter to enter the machine. There is no standard requirement for the type of Air connector and it is designed to be non-standard connector. The regulator in the high-pressure O2 limb reduces the supply gas pressure and stabilizes it at 2.0±0.1bar to ensure stable output and good repeatability of solenoid proportional valve PSOL at the rear end.

► Remove the O2 Flow Sensor

1. Remove the O2 inlet assembly.

2. Remove the 2 M3X20 combination screws fixing the O2 flow sensor anchor plate. Remove the O2 sensor and filter net.

► Check the accuracy of O2 flow sensor

This test is to check the consistency of measurement among the internal flow sensors and the accuracy of measurement of each flow sensor, as well as validating the effectiveness of flow calibration.

Connect high pressure O2 supply and make sure that the gas supply is sufficient. Increase the flow of O2 proportional valve, causing the valve opening flow to fall within the following ranges respectively: (3±0.5)L/min,(10±1)L/min,(20±1)L/min,(30±2)L/min,(60±3)L/min. Record the measured flow values of the O2 flow sensor of each setting point under stable state. Make sure that the deviation between the measured value of the O2 proportional valve and that of the O2 flow sensor shall be less than max (2L/min, measured value of O2 flow sensor x 20%).
