[0050] The circulation drive assembly 20 includes a support housing 21, a pump body 22, and a control circuit board 23. The support housing 21 is detachably connected to the connection port 12 on the water tank 10, and the support housing 21 can rotate relative to the connection port 12. The pump body 22 and the control circuit board 23 are both housed in the support housing 21, and the control circuit board 23 is electrically connected to the pump body 22.

[0051] After the control circuit board 23 is connected to an external power source, it controls the operating power of the pump body 22 when it starts and the time interval between two adjacent starts through the driver stored inside it, so as to inject simulated liquid into the simulated dummy 70, and the simulated liquid is injected into the water tank 10 through the liquid inlet 11.

[0052] When the time interval between two starts of the pump body 22 is less than the time interval between two normal heartbeats in the human body, it is used to simulate the state of accelerated heartbeat in the human body. When the time interval between two starts of the pump body 22 is greater than the time interval between two normal heartbeats in the human body, it is used to simulate the state of decelerated heartbeat in the human body. At the same time, by adjusting the starting power of the pump body 22, different contractile abilities of the human heart can be simulated.

[0053] A handle 30 is provided on the side wall of the water tank 10 to facilitate the operator in carrying the blood circulation simulation device.

[0054] Compared with the prior art, the blood circulation simulation device provided in this application includes a water tank 10, a circulation drive assembly 20, and a handle 30. The water tank 10 is used to store simulated liquid and has an inlet 11. The circulation drive assembly 20 includes a support housing 21, a pump body 22, and a control circuit board 23. The support housing 21 is detachably connected to the water tank 10. The pump body 22 and the control circuit board 23 are both housed in the support housing 21 and are electrically connected to the pump body 22 to control the operating power of the pump body 22 when it starts and the time interval between two adjacent starts, so as to inject simulated liquid into the simulated dummy 70. The simulated liquid is injected into the water tank 10 through the inlet 11. The handle 30 is provided on the side wall of the water tank 10 to facilitate the operator to carry the blood circulation simulation device. During operation, the installation can be quickly completed by connecting the inlet 11 on the water tank 10 to the outlet on the target dummy through a pipe, and connecting the outlet on the pump body 22 to the inlet 11 on the target dummy through a pipe.

Subsequently, by pressing the acceleration button 25, deceleration button 26, power increase button 27, or power decrease button 28 respectively, the control unit in the control circuit board 23 calls the control program set inside it corresponding to the above buttons, so as to adjust the time interval between the two starts and the starting power of the pump body 22 in the blood circulation simulation device, so as to simulate the blood flow rate of the human body under different conditions.

[0057] After completing the human blood circulation simulation training, press the switch button 24 again, and the control unit in the control circuit board 23 will control the pump body 22 to disconnect the power.

When installing the bearing housing 21 onto the connection port 12, the bearing housing 21 can be installed on the sealing cover 60 first, so that the switch button 24, acceleration button 25, deceleration button 26, power increase button 27, and power decrease button 28 are respectively inserted into the corresponding through holes. During the threaded connection between the sealing cover 60 and the connection port 12, the bearing housing 21 rotates relative to the connection port 12.
