[0034] The purpose of the utility model is to enable the user (medical institution) to periodically detect the used bubble detection system, so as to ensure the reliability of the bubble detection system.

[0038] The injection interface 400 is arranged in the middle part of the first pipeline 101, the injection interface 400 is used for being connected with an external syringe, the syringe is used for injecting gas, and the gas is mixed with the simulated blood in flow through the first pipeline 101. The mixing device 100 uniformly mixes the simulated blood at a certain rate, so as to ensure that the injected gas in the simulated blood cannot be dissolved by the simulated blood.

[0039] The liquid pump 200 provides power for the simulated blood, so that the simulated blood can circulate in the circulating pipeline, so that the blood flow state in the human body can be simulated.

[0040] The simulation blood is driven by the liquid pump 200 to flow out of the mixing device 100, and sequentially passes through the liquid pump 200, the observation device 300, and returns to the mixing device 100.

[0041] When it is necessary to periodically detect the reliability of the bubble detection system, a syringe can be inserted into the injection interface 400 to push a set amount of gas (which is used to simulate the bubbles introduced in the blood transfusion or infusion process) into the simulation blood.
