The heart pump 5 is a reciprocating piston pump, and the heart is driven to contract and expand repeatedly by the piston pump, and in the embodiment, the piston can be a gas.
In the embodiment, the inner walls of the blood vessel pipelines at the aorta, intracranial artery, iliac artery and abdominal aorta of the blood vessel network are provided with water pressure sensors; the branch blood vessel is formed by sequentially communicating a plurality of sections of blood vessels; the blood vessels are communicated through a blood vessel joint 11; the aortic vessel 9 and the branch vessels communicate with each other through a vessel junction 11. The blood vessel comprises a tumor blood vessel model, a thrombus model and other replaceable lesion blood vessel models; alternative lesion vessel models include stenotic, bifurcated, calcified lesion vessel models.
As shown in fig. 5, the vascular access tip 11 has an inlet inner diameter larger than the inner diameter of the blood vessel to which it is attached; the outlet inner diameter of the vascular joint 11 is smaller than the inner diameter of a blood vessel connected with the vascular joint, so that the trafficability of the catheter guide wire in the vascular system is ensured and the catheter guide wire cannot be blocked by the vascular joint 11. As shown in fig. 4, the lower part of the vascular network is provided with a plurality of transparent supports 10; the lower end of the transparent support 10 is fixedly arranged on the partition board 2. The transparent support 10 is arranged to ensure that a plurality of branch blood vessels keep a three-dimensional shape, and the observation experiment is prevented from being influenced by messy placement.
The lower shell is used for supporting the partition board 2, the simulated vascular pipeline 3 and the like, and the upper shell only plays a role in protecting and increasing the fidelity of the whole appearance. The simulated vascular pipeline 3 is a whole-body cardiovascular system required for demonstration and test of interventional devices, and simplified treatment is carried out according to human blood vessels. The simulated blood vessel pipeline 3 is used for simulating a human blood system and dispersing liquid pumped out by the systemic blood vessel pulsating pump 6 to each branch blood vessel. The liquid collection circuit 4 is responsible for collecting and returning the flowing liquid in the artificial blood vessel 3 above the partition 2 to the pump body, thereby providing circulating liquid. The utility model has two independent pipeline systems, namely a middle vascular network and an independent heart 8, and realizes double driving by two pumps, the outlet of a whole body vascular pulsating pump 6 is connected with an aorta vessel 9, liquid is pumped into the vascular network, and flows into a liquid collecting loop 4 after flowing through each branch vessel; the collecting pipe of the liquid collecting loop 4 is connected with the inlet of the systemic vascular pulsation pump 6, and the liquid forms unidirectional circulation through the systemic blood vessels.
In the test, the systemic vascular pulsation pump 6 generates pulses to simulate pulsating blood in the human body. The pulse rhythm generated by the systemic vascular pulsation pump 6 and the reciprocating rhythm of the beating heart pump 5 are synchronized to simulate the contraction and expansion of the heart in the real human body to be synchronized with the liquid pulse in the blood vessel. Two sets of drives are divided to ensure that each branch vessel of the vessel network can have sufficient water pressure generated by pulse fluid so as to simulate blood pressure; if a single pump directly drives the heart to generate pulse, the water pressure in the pipeline is greatly weakened because the heart is soft, and the aim of simulating blood pressure cannot be fulfilled.
In this embodiment, the coronary stent is used for coronary stenosis treatment, and when the coronary stent is operated, the systemic vascular pulsation pump 6 and the beating heart pump 5 are simultaneously turned on through the unified switch system. Then the red simulated blood is added into the systemic vascular pulsation pump 6, the pulse is generated by the driving of the pump, and the red liquid can quickly reach the aorta along the liquid supply main pipe and is dispersed to each branch blood vessel, and further flows into the liquid collecting loop 4 under the clapboard 2 and returns to the systemic vascular pulsation pump 6. The beating heart pump 5 drives the heart to expand and contract continuously, and the frequency of the beating heart pump is consistent with the pulse frequency in the vascular system. After 5-10 minutes of circulation, the water pressure distribution in the system is kept stable, and the water pressure is measured by a pressure measuring sensor in the vascular system to ensure that the water pressure is consistent with the blood pressure of the human body at each position. Then the catheter guide wire loaded with the coronary artery enters the path from the radial artery, passes through the subclavian artery and the aorta, reaches the coronary artery, and then specifically reaches the stenotic lesion, and releases the stent. The pressure sensor in the vascular system can monitor the change of local water pressure in the operation process in real time and is used as an index for evaluating the operation level, so that an operation system close to a real environment is provided for training personnel.

The beating heart pump 5 drives the heart to expand and contract continuously, and the frequency of the beating heart pump is consistent with the pulse frequency in the vascular system. After 5-10 minutes of circulation, the water pressure distribution in the system is kept stable, the pressure sensor in the vascular system measures the water pressure to ensure that the pressure is consistent with the blood pressure of the human body at each position, and then the catheter guide wire loaded with the spring ring enters the way from the femoral artery, passes through the aortic arch and the carotid artery, reaches the intracranial space, particularly reaches the aneurysm, and releases the spring ring.
