Since the volume size of the standard cavity 100 is consistent with the volume size of the detection cavity 200, the initial air pressure in the detection cavity 200 is completely consistent with the initial air pressure in the standard cavity 100. In the initial state, the air pressure data displayed on the first pressure gauge and the second pressure gauge are consistent. Then, a pump body is used to increase the pressure of the standard cavity 100, for example, by increasing the pressure of the standard gas by 50 kPa. At this time, the air pressure in the standard cavity 100 will be greater than the air pressure in the detection cavity 200. Finally, another pump body is used to draw the pressurized gas in the standard cavity 100 into the detection cavity 200, and the pressurized air pressure data is displayed on the second pressure gauge 510. When the increased data on the second pressure gauge 510 is 50 kPa, it is judged that the blood separation cup to be tested in the detection cavity 200 is qualified; otherwise, it is unqualified. Through this setting, the technical problem of unreliable detection method of blood separation cup in the prior art can be solved.
