[0002] Right ventricular valvular disease severely impacts patient survival. Transcatheter interventional techniques are renowned for their safety and effectiveness, and have demonstrated promising results in treating right ventricular valvular disease. However, it remains a relatively new and developing technology.

[0003] Transcatheter implantation of an artificial heart valve is a complex cardiac procedure that requires rigorous extracorporeal hydrodynamic testing before surgery to ensure safety and effectiveness during the procedure. These tests need to simulate various scenarios during heart valve reoperation, including closure and opening, expansion and contraction.

[0004] The technical details still require in-depth study and widespread application. Currently, simulation can only be performed using 3D-printed models of the patient's right heart. However, within the heart chambers and blood vessels, the operation and positioning of instruments and guidewires under the influence of blood flow require greater precision to ensure accurate instrument placement.

[0023] Example 1

[0024] To address the issue that existing pulsatile conduit models cannot simulate the impact of blood vessels on transcatheter interventional treatment of right heart valves.

[0025] This utility model provides a method such as Figures 1-4The pulsatile conduit model shown is used to connect to a right heart valve simulator for transcatheter interventional therapy. It includes a model body 1, which is a heart model made using existing 3D printing technology based on the patient's heart. The model body 1 is provided with a fluid passage that simulates blood flow; it can simulate the flow of blood within the heart. The model body 1 is housed within the model mounting housing 2. Module mounting shafts 3 are symmetrically arranged inside the model mounting housing 2. Model mounting seats 4 are located on the left and right sides of the model body 1. The module mounting shafts 3 and model mounting seats 4 are rotatably connected, allowing the model body 1 to be rotatably mounted within the model mounting housing 2. This facilitates pipe connections after rotating the model body 1, enabling simulated fluid to enter the model body 1 and simulate blood flow. Specifically, the module mounting shaft 3 is a connecting shaft, and the model mounting seat 4 is a retainer located outside the connecting shaft, capable of rotating around the connecting shaft. Multiple simulated liquid inlet channels 5 are provided on one side wall of the left and right sides of the model mounting housing 2, and multiple simulated liquid outlet channels 6 are provided on the other side wall of the left and right sides of the model mounting housing 2. The simulated liquid inlet channels 5 and simulated liquid outlet channels 6 cooperate to allow simulated liquid to enter the model body 1 through the simulated liquid inlet channels 5 and then flow out through the simulated liquid outlet channels 6.

[0026] Furthermore, each of the plurality of simulated liquid inlet channels 5 is equipped with an inlet control valve 7; and each of the plurality of simulated liquid inlet channels 5 is equipped with an inlet convex retaining ring 8 at both ends.

[0027] Furthermore, each of the plurality of simulated liquid outlet channels 6 is equipped with an outlet control valve 9; and each of the plurality of simulated liquid outlet channels 6 is equipped with an outlet retaining ring 10 at both ends.

[0028] The inlet control valve 7 and the outlet control valve 9 are both used to adjust and control the simulated liquid in the corresponding pipelines, so that the simulated liquid can be adjusted according to the needs of the surgery, thereby simulating the surgical process more realistically.

[0029] The inlet convex retainer 8 and outlet convex retainer 10 are clamps for connecting pipelines to prevent the simulated liquid from flowing out of the pipeline and causing errors in the simulation effect.

[0030] Furthermore, the plurality of simulated liquid inlet channels 5 are connected to the diversion device 11 via pipelines, the diversion device 11 is connected to the heating device 12 via pipelines, the heating device 12 is connected to the simulated liquid storage device 13 via pipelines, the simulated liquid storage device 13 is connected to the manifold device 14 via pipelines, the manifold device 14 is connected to the simulated liquid outlet channel 6 via pipelines, and the pipelines between the simulated liquid storage device 13 and the manifold device 14 are also equipped with a liquid pump 15.

[0031] Furthermore, the diversion device 11 includes a main body, which is a hollow cuboid. A liquid inlet is provided on one side of the main body, and multiple liquid outlets are provided on the other side of the main body, so that one liquid can be diverted into multiple streams.

[0032] Furthermore, the structure of the confluence device 14 is exactly the opposite of that of the diversion device 11. The confluence device 14 also includes a hollow cuboid body with multiple liquid inlets on one side and a liquid outlet on the other side, so that multiple liquids can be combined into one liquid.

[0033] Furthermore, the simulated liquid storage device 13 is an existing liquid storage tank, which is equipped with an inlet, an outlet, and a tank opening for adding liquid.

[0034] Furthermore, the liquid pump 15 is a 24V miniature intelligent liquid pump, model BSP40160T.

[0035] Furthermore, the heating device 12 is a liquid electric heater that operates on 220V AC power, and its model is FJ-SX.

[0036] The aforementioned liquid pump 15 and heating device 12 are both controlled by a control system that controls a relay. The relay controls the circuit switch of the liquid pump 15 or heating device 12, thereby controlling the working status of the liquid pump 15 and heating device 12.

[0037] The diversion device 11 is used to divert the simulated liquid into multiple channels so that it can flow into different simulated liquid inlet channels 5; the confluence device 14 is used to merge the simulated liquid flowing out of the simulated liquid outlet channel 6 so that it can flow into the simulated liquid storage device 13; the heating device 12 is used to heat the simulated liquid to simulate the temperature of blood and further imitate the real state of blood; the liquid pump 15 is used to pressurize the simulated liquid in the simulated liquid storage device 13, which can simulate the blood pressure effect, and also provide power to ensure that the simulated liquid can flow realistically in the model body 1.

[0038] Furthermore, a T-junction 16 is provided in the pipeline between the diversion device 11 and the heating device 12. The T-junction 16 is connected to the simulated liquid storage device 13 via a pipeline, and a regulating valve 17 is provided on the pipeline connecting the T-junction 16 and the simulated storage device 13. By adjusting the on / off state of the valve 17, the flow rate and pressure of the simulated liquid flowing into the diversion device 11 can be regulated to ensure a more realistic surgical effect.

[0039] Furthermore, Figure 3The control system shown can employ an existing intelligent control system with functions such as pump monitoring, liquid monitoring, pump drive, and relay control. Figure 5 As shown, the control system includes multiple data acquisition sensors, a signal amplification module, an AD conversion module, and a control module. The multiple data acquisition sensors are electrically connected to the signal amplification module, the signal amplification module is electrically connected to the AD conversion module, the AD conversion module is electrically connected to the control module, and the control module is electrically connected to the fluid pump via catheter intervention right heart valve simulator 15, the heating device via catheter intervention right heart valve simulator 12, and various pipeline valves.

[0040] In summary, the pulsatile conduit model used in the transcatheter interventional right ventricular valve simulator can simulate blood flow within the pulsatile conduit model, thereby more realistically simulating the process of transcatheter interventional right ventricular valve treatment. This allows doctors to simulate the surgery in a model that is closer to the real environment before performing the actual surgery, thus improving the success rate of the surgery.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
