[0030] This disclosure aims to address the problems of existing biomimetic dynamic simulation processes for implanted mechanical heart valves, which typically require extensive human intervention at every step and suffer from significant human error in the data obtained. Therefore, this disclosure proposes a biomimetic dynamic simulation device for implanted mechanical heart valves. By incorporating detection devices and simulating the human body environment, the device tests the mechanical heart valve. The simulation chamber enhances the accuracy of test results by mimicking the human body environment. Furthermore, by highly simulating the natural working state of the heart valve, it provides a precise and controllable experimental environment, enabling researchers to meticulously observe and evaluate the performance of the artificial valve under simulated real blood flow conditions. This accelerates valve design optimization and innovation, improves the success rate of valve replacement surgery, and enhances patients' postoperative quality of life.

[0031] like Figures 1 to 7 As shown, a biomimetic dynamic simulation device for implanted mechanical heart valves includes a simulation frame 1, a sealed outer shell 2, an environmental control component 3, a pumping mechanism 4, and a detection mechanism 5. The simulation frame 1 is fixed, and the sealed outer shell 2 is installed inside the simulation frame 1. The environmental control component 3 is installed inside the sealed outer shell 2 to adjust the temperature, humidity, and other indices inside the sealed outer shell 2, thereby simulating the human body environment under different conditions. The pumping mechanism 4 is installed inside the sealed outer shell 2 and is used to simulate human blood flow to cooperate with the detection mechanism 5 in detecting the mechanical heart valve. The detection mechanism 5 is installed on one side of the pumping mechanism 4 and is used to fix the mechanical valve and cooperate with the pumping mechanism 4 to detect the artificial heart valve.

[0032] By setting up a testing device and simulating the human body environment, mechanical heart valves can be tested. The simulation chamber 53 simulates the human body environment, making the test results more accurate. At the same time, by highly simulating the natural working state of the heart valve, a precise and controllable experimental environment is provided, allowing researchers to carefully observe and evaluate the performance of artificial valves under simulated real blood flow conditions. This accelerates the optimization and innovation of valve design, improves the success rate of valve replacement surgery, and enhances the postoperative quality of life of patients.

[0033] like Figures 1 to 5 As shown, the testing mechanism 5 includes a testing frame 51, a testing chamber 52, a simulation chamber 53, and a fixing frame 54. The testing frame 51 is mounted on the simulation frame 1; the testing frame 51 is used to fix the testing mechanism 5; the testing chamber 52 is mounted on the testing frame 51 and is used to place the simulation chamber 53; the simulation chamber 53 is installed inside the testing chamber 52 and is used to highly simulate the natural working state of the heart valve; the fixing frame 54 is installed inside the simulation chamber 53 and is used to fix the heart valve.

[0034] During operation, the staff first place the heart valve in the simulation chamber 53. At this time, the pumping mechanism 4 starts pumping to simulate blood flow. When the blood flows to the heart valve in the simulation chamber 53, the heart valve delivers blood through periodic opening and closing. At this time, the staff can determine whether the heart valve meets the relevant standards by measuring the flow rate and flow volume.

[0035] Using the aforementioned testing device 5, heart valve testing can be achieved with just one placement action. At the same time, by highly simulating the natural working state of heart valves, it provides a precise and controllable experimental environment, enabling researchers to meticulously observe and evaluate the performance of artificial valves under simulated real blood flow conditions. This accelerates the optimization and innovation of valve design, improves the success rate of valve replacement surgery, and enhances the postoperative quality of life for patients.

[0036] like Figure 5 As shown, the simulation chamber 53 has a receiving hole at the bottom, which is connected to the pumping mechanism 4. The receiving hole simulates the blood vessels in the heart, so that the heart valves can adapt to the expansion and contraction when the liquid flows in. Then, the movement of the heart valve leaflets is recorded by the high-speed camera 6.

[0037] like Figures 1 to 3 As shown, the detection chamber 52 is equipped with constant temperature heating rods 55 around its perimeter to ensure the internal temperature of the detection chamber 52. The constant temperature heating rods 55 simulate normal human body temperature, thereby ensuring the accuracy of the test data. The constant temperature heating rods 55 can precisely control the temperature of the simulated skin, adjusting the surface temperature of the simulated human body at a rate similar to the human body temperature regulation in an environment between 15-45℃.

[0038] like Figures 1 to 7 As shown, a rubber pad is installed inside the fixing frame 54. The rubber pad is used to fit heart valves of different sizes, thereby achieving their normal fixing function.

[0039] like Figure 7As shown, the environmental control component 3 includes a humidifier 31, a thermostat 32, and a vibrator 33. The humidifier 31 and the thermostat 32 are installed inside the sealed housing. The humidifier 31 is used to simulate the humidity of the human body. The vibrator 33 is installed on one side of the simulation chamber 53. The thermostat 32 is used to ensure that the temperature inside the sealed housing 2 is constant. The vibrator 33 is used to vibrate to simulate the beating of the heart.

[0040] like Figures 1 to 3 As shown, the pump mechanism 4 includes a booster pump 41 and a delivery pipe 42. The booster pump 41 is installed on one side of the detection mechanism 5 and is used to pressurize and deliver water. The delivery pipe 42 is installed on one side of the booster pump 41 and is used to deliver liquid. The delivery pipe 42 passes through the detection chamber 52 and is connected to the simulation chamber 53. The other end of the simulation chamber 53 is equipped with a delivery pipe 42 for discharging the detection liquid.

[0041] like Figure 1 As shown, an electromagnetic flow meter 43 is installed on the infusion tube 42. The electromagnetic flow meter 43 is used to detect the flow rate of the liquid, thereby enabling the determination of whether the heart valve is working properly by detecting the flow rate data.

[0042] like Figures 1 to 7 As shown, the detection chamber 52 and the simulation chamber 53 are both made of high-transparency material. A high-speed camera 6 for recording valve movement is installed inside the sealed outer shell 2. The height camera is used to record the movement of the heart valve leaflets. Under the action of the detection chamber 52 and the simulation chamber 53 made of high-transparency material, the amplitude of the heart valve leaflet movement can be directly detected by the high-speed camera 6, thereby determining whether the heart valve is working properly.

[0043] The overall working process is as follows: The staff first places the heart valve in the simulation chamber 53. At this time, the pumping mechanism 4 starts to pump fluid to simulate blood flow. When the blood flows to the heart valve in the simulation chamber 53, the heart valve delivers blood through periodic opening and closing. At this time, the staff can determine whether the heart valve meets the relevant standards by measuring the flow rate and flow volume.

[0044] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
