[0020] The utility model will be further discussed in detail in combination with the following Figures 1-5 The utility model will be further discussed in detail in combination with the following

[0021] like Figure 1 As shown, an intra-aortic balloon counterpulsation testing and demonstration device includes a humanoid support plate 10, on which is fixed a vascular tube 20 aligned with the position of the human arterial system. An intra-aortic balloon counterpulsation pump 30 is inserted from the femoral artery port of the vascular tube 20 into the descending aorta. The end of the vascular tube 20 is connected by a water pipe 70, which is equipped with a pulsating pump 40 to provide pulsating fluid to the vascular tube 20. The vascular tube 20 is also connected to a counterpulsation test unit 60 via a connecting pipe 50. The humanoid support plate 10 not only provides a support base for the testing device, but also displays the basic positions of the human body, making it easier to fix the vascular tube 20 in the appropriate position. The vascular conduit 20 is designed based on the distribution, location, and size of the human aorta. It is a hollow structure and is secured to the support plate 10 via support blocks. By designing the support block height and the angle of the bayonet, the vascular conduit 20 is a 3D structure that aligns with the distribution of the actual human vascular system. The pulsatile pump 40 acts as an artificial heart. Because the blood flow ejected by the heart is pulsatile, the pulsatile pump 40 also simulates the heart, providing pulsatile fluid to the vascular conduit 20 and circulating the fluid within the conduit. After the intra-aortic balloon counterpulsation pump 30 is inserted from the femoral artery into the descending aorta, the intra-aortic balloon counterpulsation pump 30 is activated. During the inflation process, the balloon squeezes fluid into the counterpulsation test unit 60, which measures and displays the counterpulsation volume. This device can not only be used to measure the counterpulsation volume of the intra-aortic balloon counterpulsation pump 30 and reflect the counterpulsation effect, but also measure the actual volume of the balloon; it can also be used as a teaching display device to demonstrate the correct intervention position of the intra-aortic balloon counterpulsation pump 30, and can also be used by doctors and trainees for practice.

[0022] See Figure 2 As shown, the specific structure of the counterpulsation test unit 60 is as follows: the counterpulsation test unit 60 includes a water tank 61 placed on the support plate 10, an air tank 62 and a vertically arranged measuring tube 63 are provided above the water tank 61, the surface of the measuring tube 63 has a scale, the lower pipe mouth of the measuring tube 63 is connected to the water tank 61, and the upper pipe mouth is connected to the air tank 62 through a hose 64. When the balloon is inflated, a portion of the liquid will enter the measuring tube 63 from the water tank 61. The surface of the measuring tube 63 has a scale, which can directly display the counterpulsation amount, which is intuitive and reliable. Since there is a certain pressure in the blood vessels, in order to simulate the pressure, the upper pipe mouth of the measuring tube 63 is connected to the air tank 62 to provide a gas compression buffer.

[0023] In order to regulate pressure, the top of the gas tank 62 is provided with a pressure gauge 65 and a gas exhaust valve 66, and the gas tank 62 is also communicated with a pressurized air bag 68 through a gas pipe 67. The pressure gauge 65 is used to detect the pressure fluctuation in the gas tank 62, the gas exhaust valve 66 is used to discharge gas and reduce pressure, and the pressurized air bag 68 is used to pressurize the gas tank 62 and make up for the loss of pressure.

[0024] Further, the vessel pipeline 20 includes a left femoral artery pipeline, a right femoral artery pipeline, an ascending aorta pipeline, an aortic arch, and a descending aorta pipeline, and the vessel pipeline 20 is fixed on the support plate 10 by the support block and the length and deflection angle between each pipeline segment are consistent with the physiological structure of the human arterial system. One end of the water pipeline 70 is connected to the free pipeline end of the ascending aorta pipeline, and the other end is connected to the free pipeline end of the left / right femoral artery pipeline. The vessel pipeline 20 is mainly arranged in the ascending aorta part from the aorta to the heart.

[0025] In order to prevent liquid leakage in the vessel pipeline 20, the intra-aortic balloon counterpulsation pump 30 is inserted from the free pipeline end of the left / right femoral artery pipeline, and the free pipeline end is provided with a sealing joint 80. The sealing joint 80 not only allows the intra-aortic balloon counterpulsation pump 30 catheter to pass through, but also ensures that the sealing state is maintained between the femoral artery pipeline end and the catheter outer wall, thereby preventing liquid leakage.

[0026] In order to ensure that the temperature of the liquid is consistent with the human blood pressure, a constant temperature heating unit 71 is further arranged on the water pipeline 70 between the left / right femoral artery pipeline and the pulsatile pump 40 to simulate the human body temperature.

[0027] The specific structure of the sealing joint 80 is shown in Figure 3 、 Figure 4 The sealing joint 80 includes an outer shell 81, the shell 81 includes a large diameter section and a small diameter section, the small diameter section is inserted into the femoral artery pipeline, the outer wall of the small diameter section is in sealing cooperation with the inner wall of the femoral artery pipeline, the inner cavity of the large diameter section is in the shape of a tapered hole, a tapered sealing body 82 is arranged in the tapered hole inner cavity, the small diameter end of the sealing body 82 abuts against the step between the small diameter section and the large diameter section, the outer thread of a rotating locking member 83 is in locking cooperation with the inner thread of the inner cavity of the large diameter section, the rotating locking member 83 abuts against the large diameter end of the sealing body 82, and the rotating locking member 83, the sealing body 82, and the small diameter section inner cavity are all provided with through holes for the intra-aortic balloon counterpulsation pump 30 catheter to pass through. Among them, the shell 81 is connected with the femoral artery pipeline opening, and at the same time, the shell 81 guides the deformation of the sealing body 82, and the opening has an inner thread, which cooperates with the rotating locking member 83 to lock the position of the sealing body 82.

[0028] Further, as shown in Figure 5As shown, the sealing body 82 is made of soft silica gel or rubber air bag, the orifice of the through hole near one side of the rotating locking member 83 is provided with a cross seal structure, and the orifice of the through hole near one side of the step is radially contracted and wrapped around the outer periphery of the aortic balloon counterpulsation pump 30 catheter after being pressed.

[0029] Further, the vascular pipeline 20 is made of soft transparent silica gel or hard transparent resin material, so as to facilitate observation of internal blood flow and the position of the balloon.
