[0003] When testing the instrument, the user needs to use a disassembly valve to calibrate the instrument being tested. When the instrument is reinstalled, the tester cannot observe the pressure change in time, resulting in the need for multiple people to operate and multiple devices to be connected and moved. The operation is cumbersome, and the online monitoring equipment is prone to damage to the detection system when it is offline and disassembled, causing great risks. When testing, the detection equipment needs to be sent for inspection, which will cause system shutdown, affect the normal use of the device, and affect the normal detection work of the hospital. For this reason, we provide a medical gas system in-situ measurement and detection standard device to solve the above problems. Utility Model Content
