The implementation steps are as follows: the pressure is first determined and vented using the normal extracorporeal circulation mode, as shown in fig. 4, with the clamp closing the line connecting reservoir a1 to reservoir B2 and reservoir a1 to the pressure controller 9 (clamp position is shown/indicated). The liquid pumped by the rolling pump 4 passes through the pressure controller 9 and does not enter the blood storage tank A1 any more, and the gas in the system is discharged by simulating the conventional extracorporeal circulation condition. After the pressure is determined, the evacuation mode is changed to the one shown in fig. 3, and the connection line between the blood storage tank a1 and the blood storage tank B2, and the connection line between the blood storage tank B2 and the pressure controller 9 are clamped closed by the clamp. The liquid pumped by the rolling pump 4 can only be discharged into the blood storage tank 1 after passing through the pressure controller 9, and cannot flow back to the blood storage tank B2, so that the emptying condition of the blood storage tank B2 is simulated. The drain time is tested and the test can be repeated after the test is completed using the system exhaust mode (as shown in fig. 2, without any clamping).

The liquid pumped by the rolling pump 4 passes through the pressure controller 9 and does not enter the blood storage tank A1 any more, and the gas in the system is discharged by simulating the conventional extracorporeal circulation condition. And changing the pressure or negative pressure into a liquid supplement mode, and adding liquid to adjust the concentration. As shown in fig. 5 (shown in phantom/indicating that the jaw position is selectively openable), the connection between the blood tank a1 and the pressure controller 9 is clamped closed by the jaws; at the same time, the connecting line between the blood storage tank A1 and the blood storage tank B2 is also clamped by the clamp and is opened only when different concentrations are adjusted.
