[0002] At present, the existing vascular suturing devices are extremely complex and precise inside and have relatively harsh operating environments. Therefore, various problems may arise during the suturing process, resulting in a reduced success rate of suturing. In order to continuously optimize the vascular suturing devices and meet the training and practice requirements of assembly and operation, a vascular simulation device is needed to simulate the vascular suturing process.

[0003] It is known that a Chinese invention patent (CN111816043A) discloses a vascular interventional surgery simulator, including a water pump, a water inlet tank, a basic blood vessel model, a cerebrovascular model, a cardiovascular model, a femoral blood vessel model, a contrast agent and a contrast imaging device. The water pump, the water inlet tank and the basic blood vessel model are used to simulate the human blood circulation system; the cerebrovascular model, the cardiovascular model and the femoral blood vessel model are used to simulate the high-incidence sites of human vascular diseases; the contrast agent is added to the water inlet tank to match the contrast imaging device and simulate the contrast imaging image in the working environment; and the colored film is covered on each blood vessel model to simulate the real working environment of the operation. The device cannot simulate the different conditions of the puncture site caused by different diseases of the patient, and the device is complex and the cost of the blood vessel model is high, which is not suitable for testing needs.

[0004] Therefore, there is an urgent need to design a simple vascular simulation device that can meet testing requirements. Utility Model Content

[0032] Embodiment 1

[0033] Combination Figure 1 and Figure 2 , a blood vessel simulation device, comprising:

[0034] The liquid storage unit 100 contains liquid;

[0035] A self-priming pump 200 is disposed in the liquid storage unit 100; the self-priming pump 200 extracts liquid;

[0036] The simulated blood vessel unit 600 is connected to the self-priming pump 200; the liquid in the liquid storage unit 100 is pumped out by the self-priming pump 200 and transported to the simulated blood vessel unit 600;

[0037] The weighted ball 900 is disposed in the liquid storage unit 100;

[0038] The connecting pipe includes a first pipe and a second pipe, one end of the first pipe is connected to the self-priming pump 200, and the other end of the first pipe is connected to the simulated blood vessel unit 600, and the first pipe and the simulated blood vessel unit 600 are detachably connected; one end of the second pipe is connected to the simulated blood vessel unit 600, and the other end of the second pipe is connected to the counterweight ball 900; the counterweight ball 900 is configured to make the end of the second pipe sink to the bottom of the liquid storage unit 100.

[0039] This embodiment provides a blood vessel simulation device, which can quickly replace the simulated blood vessel unit 600, simulate the suturing environment of patients with different disease conditions, and test the blood vessel suturing device.

[0040] In this embodiment, the liquid storage unit 100 is an open container, the interior of which is connected to the atmosphere, which can effectively avoid the generation of overall negative pressure. The open container can be a liquid storage cup; the liquid is clean water with a recognizable color.

[0041] In this embodiment, the rated pressure of the self-priming pump 200 is not less than 0.4 MPa. After the self-priming pump 200 is placed in the liquid storage unit 100, the liquid level of the liquid storage unit 100 must be higher than the water suction port of the self-priming pump 200, thereby ensuring that no gas enters the loop in the connecting pipeline.

[0042] In this embodiment, the simulated blood vessel unit 600 can use animal blood vessels (such as bovine heart tubes, sheep intestines, etc.), silicone tubes, polypropylene braided tubes, etc. to simulate normal blood vessels and calcified blood vessels, and can also cover different muscle tissues to simulate the puncture environment of different patients to test the blood vessel suturing device. It can be understood that the two ends of the simulated blood vessel unit 600 are respectively set on the first pipeline and the second pipeline.

[0043] In this embodiment, the first pipeline includes a first connecting tube 301, a second connecting tube 302 and a third connecting tube 303, and the second pipeline includes a fourth connecting tube 304. The first connecting tube 301, the second connecting tube 302 and the third connecting tube 303 are connected through a first joint 801, and a simulated blood vessel unit 600 is provided between the third connecting tube 303 and the fourth connecting tube 304. Specifically, the two ends of the simulated blood vessel unit 600 are detachably connected to the third connecting tube 303 and the fourth connecting tube 304 respectively through a tube clamp 601. When the two ends of the simulated blood vessel unit 600 are respectively sleeved on the third connecting tube 303 and the fourth connecting tube 304, the tube clamp 601 clamps the two ends of the simulated blood vessel unit 600 to the third connecting tube 303 and the fourth connecting tube 304 respectively.

[0044] Furthermore, the first connecting pipe 301 is a pressure-resistant hose, and the first connecting pipe 301 is provided with a pressure regulating valve 400, and the pressure regulating valve 400 is used to adjust the pressure.

[0045] The second connecting pipe 302 is provided with a pressure gauge 500, and the pressure gauge 500 is used to monitor the pressure. The pressure gauge 500 is placed on the same level as the simulated blood vessel unit 600 as much as possible to reduce errors.

[0046] Among them, the first connector 801 is a three-way connector, and the first connecting pipe 301 at the output end of the self-priming pump 200 is divided into two branches through a three-way connector, namely the first branch, namely the second connecting pipe 302, and the second branch, namely the third connecting pipe 303. The second connecting pipe 302 is connected to the pressure gauge 500 to monitor the pressure in the connecting pipe in real time. The third connecting pipe 303 is connected to the simulated blood vessel unit 600 and refluxes to the liquid storage unit 100 to form a circulation.

[0047] The third connecting tube 303 and the fourth connecting tube 304 can be made of pressure-resistant hard connecting tubes. It should be noted that, according to the size of the experimental occasion, the third connecting tube 303 and the fourth connecting tube 304 can have multiple sections, such as Figure 1 As shown, multiple sections of the third connecting pipe 303 are connected via the second joint 802, and multiple sections of the fourth connecting pipe 304 are connected via the third joint 803, wherein the pipe connected to the weighted ball 900 is a pressure-resistant hose.

[0048] In some other possible embodiments, the third connecting tube 303 and the fourth connecting tube 304 are respectively fixed to the base plate through the support seat 700. Since the third connecting tube 303 and the fourth connecting tube 304 are both pressure-resistant hard connecting tubes with a certain weight, the support seat 700 can prevent the third connecting tube 303 and the fourth connecting tube 304 from sinking due to their own gravity, thereby ensuring that the simulated blood vessel unit 600 and the pressure gauge 500 are on the same horizontal plane.

[0049] The working principle of this embodiment is as follows:

[0050] Assemble the system and pour clean water of identifiable color into the liquid storage unit 100;

[0051] Start the self-priming pump 200 to extract the liquid in the liquid storage unit 100 and transfer it to the simulated blood vessel unit 600, and adjust the pressure through the pressure regulating valve 400 according to the reading of the pressure gauge 500 until the pressure is required for the experiment;

[0052] Opening the simulated blood vessel unit 600, using a blood vessel suturing device to test the suturing effect, and recording the data;

[0053] The self-priming pump 200 is turned off, a different simulated blood vessel unit 600 is replaced, and the above operation is repeated and data is recorded.

[0054] After the experiment is completed, the self-priming pump 200 is turned off and disconnected, and the site is cleaned up.

[0055] Embodiment 2

[0056] This embodiment provides a simulated blood vessel suturing system, including the blood vessel simulation device provided in the first embodiment.

[0057] In this embodiment, the simulated blood vessel suturing system also includes an existing blood vessel suturing device, and the blood vessel suturing device and the blood vessel simulation device form a cooperation to test the suturing effect.

[0058] It should be noted that the main design point of the present invention lies in the structural improvement of the blood vessel simulation device, and other structures of the simulated blood vessel suturing system will not be described in detail.

[0059] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0060] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
