[0030] The atrial simulation area 21 and the arterial simulation area 23 are respectively fixedly installed with multifunctional combined heart valves simulating the tricuspid valve and / or mitral valve, pulmonary valve and / or aortic valve.

[0031] The atrium simulation area 21 and the artery simulation area 23 are horizontally slidably installed with a moving position 24, and the multifunctional combined heart valve is fixedly installed in the moving position 24. By horizontally sliding the moving position 24 outward, the multifunctional combined heart valve is conveniently installed by the operator, and after the multifunctional combined heart valve is installed, the moving position 24 is reset, so that the multifunctional combined heart valve is located in the atrium simulation area and / or the artery simulation area 23 for testing.

[0032] The pressure regulating assembly 3 comprises a telescopic base 31 and a pressure water tank 32, the telescopic base 31 is fixedly installed above the base 1, the pressure water tank 32 is fixedly installed above the telescopic base 31, one end of a communication pipe 33 is installed in the pressure water tank 32, the other end of the communication pipe 33 is fixedly connected with the upper part of the base body 2, the middle part of the base body 2 is fixedly connected with the pacing assembly 4, and the lower part of the base body 2 is fixedly connected with the circulation assembly 5.

[0033] The pressure water tank 32 stores a liquid simulating blood, and in the embodiment of the present disclosure, dextran solution is selected. The dextran solution is similar to blood in physical properties such as density and viscosity, and can fully simulate blood for testing. Of course, any liquid similar to blood in physical properties in the prior art can also be used to replace the dextran solution in the embodiment of the present disclosure.

[0034] The multifunctional combined heart valve is installed in the base body 2 for simulation testing, and the dextran solution in the pressure water tank 32 can flow into the multifunctional combined heart valve above to simulate the flow of venous blood into the atrium. With the entry of the dextran solution in the pressure water tank 32 above the multifunctional combined heart valve, whether the multifunctional combined heart valve leaks is tested by whether the dextran solution penetrates, and the telescopic base 31 can drive the pressure water tank 32 to move up and down through the telescopic performance of the telescopic base 31, so as to control the pressure when the dextran solution in the pressure water tank 32 is input, and further to simulate the pressure fluctuation of the venous blood back to the heart caused by breathing, bone compression, body posture and heart contraction and relaxation in real time. At the same time, the pressure of the dextran solution in the pressure water tank 32 on the multifunctional combined heart valve can also be controlled, and the pressure resistance of the multifunctional combined heart valve can be tested.

[0035] The ventricular simulation area 22 comprises an outer wall 221, a pressurization area 222 and an inner wall 223, the inner wall 223 is fixedly installed in the outer wall 221, and the pressurization area 222 is arranged between the outer wall 221 and the inner wall 223; the pacing assembly 4 comprises a piston air pump 41, and the pressurization area 222 is fixedly communicated with the piston air pump 41 through an air pipe 42. The outer wall 221 has a greater hardness than the inner wall 223, in the embodiment of the present disclosure, the outer wall 221 is a hard metal, and the inner wall 223 is a flexible and easily deformed rubber material, and specifically, an air bag structure is selected. The outer wall 221 and the inner wall 223 are fixedly connected, and the fixed connection points are arranged at intervals, so that the pressurization area 222 is reserved.

[0036] It should be noted that the specific structure and principle of the piston air pump 41 are prior art, and will not be described in detail.

[0037] After the dextran solution enters the ventricular simulation area 22, the piston air pump 41 is started to continuously switch to the pressurization area 222 to input air pressurization and extract air negative pressure, so as to control the space of the flexible and easily deformed inner wall 223 to perform diastole and systole, and then simulate the change of the internal space and pressure when the ventricle contracts. It should be noted that the piston air pump 41 can control the space size and diastole and systole amount of the inner wall 223 according to the input or extracted air, so as to simulate the influence of the Frank-Starling mechanism on the multifunctional combined heart valve.

[0038] The atrial simulation area 21, the ventricular simulation area 22 and the arterial simulation area 23 are arranged in at least two along the horizontal direction, one end of at least two communication pipes 33 corresponding to the atrial simulation area 21 one by one is arranged in the pressure tank 32 in the horizontal direction, and the output end of the piston air pump 41 is communicated with at least two air pipes 42 corresponding to the pressurization area 222 one by one. The atrial simulation area 21, the ventricular simulation area 22 and the arterial simulation area 23 can work synchronously or asynchronously in the horizontal direction, so as to detect multiple multifunctional combined heart valves at the same time or at different times, and then the efficiency of testing the multifunctional combined heart valve is improved.

[0039] It should be noted that the atrial simulation area 21, the ventricular simulation area 22 and the arterial simulation area 23 in the present application can be made by reverse molding of human heart structure, so that the internal structure of the atrial simulation area 21, the ventricular simulation area 22 and the arterial simulation area 23 is consistent with the human heart structure.

[0040] The first pressure detector 25 is fixedly installed in the atrium simulation area 21 and the artery simulation area 23. The atrium simulation area 21 and the artery simulation area 23 are provided with installation openings at the horizontal positions of the multifunctional combined heart valve installation, the horizontal positions of the installation openings are the same as the multifunctional combined heart valve, and the first pressure detector 25 is fixedly installed in the installation openings.

[0041] By fixing the first pressure detector 25 in the installation openings at the same horizontal height as the multifunctional combined heart valve, whether the multifunctional combined heart valve has a leakage can be tested by detecting the change of the pressure value in the atrium and / or the artery by the first pressure detector 25, and the pressure borne by the multifunctional combined heart valve can be displayed by the pressure detector, so as to test the pressure resistance of the multifunctional combined heart valve.

[0042] The end of the communication pipe 33 is provided with an electromagnetic valve 26. The time when the dextran solution in the pressure tank 32 enters the atrium simulation area 21 at a stable flow is controlled by the electromagnetic valve 26, so as to control the entering amount of the dextran solution, and the total amount and the pressure of the dextran solution in the atrium simulation area 21 can be actively controlled and set, so as to facilitate the active setting and testing of whether the multifunctional combined heart valve leaks and the pressure resistance.

[0043] The pacing assembly 4 further comprises a second pressure detector 43, and the second pressure detector 43 is fixedly installed in the inner wall 223. The second pressure detector 43 can monitor the change of the pressure in the inner wall 223, and cooperate with the pressure value monitored by the first pressure detector 25 in the atrium simulation area 21 and the artery simulation area 23 to monitor whether the multifunctional combined heart valve leaks in real time. Meanwhile, when the piston air pump 41 drives the inner wall 223 to simulate the contraction and relaxation of the heart, the second pressure detector 43 can also cooperate with the first pressure detector 25 to display the pressure difference, so that when the dextran solution passes through the artificial heart valve 27 due to the pressure difference, the instantaneous pressure difference displayed by the first pressure detector 25 and the second pressure detector 43 reflects the transvalvular pressure difference, and the transvalvular pressure difference under the dynamic pressure is reflected in cooperation with the pressure dynamically controlled by the pressure regulating assembly 3.

[0044] It should be noted that the first and second pressure detectors 43 can be any structure or device capable of detecting pressure in the prior art, and in the embodiment of the present disclosure, a pressure transmitter is adopted.

[0045] The circulation assembly 5 comprises a first liquid pipe 51, a recovery tank 52, a second liquid pipe 53 and a reflux pump 54. The arterial simulation area 23 is communicated with the recovery tank 52 through the first liquid pipe 51. The recovery tank 52 is fixedly installed with the reflux pump 54. The reflux pump 54 is communicated with the pressure tank 32 through the second liquid pipe 53. After the dextran solution enters the arterial simulation area 23, it directly enters the recovery tank 52 through the first liquid pipe 51, so that the dextran solution is transported to the pressure tank 32 again through the reflux pump 54 and the second liquid pipe 53 for recycling.

[0046] It should be noted that the second liquid pipe 53 is a hose or a telescopic bellows structure, so as to stably connect the pressure tank 32 which can be lifted.

[0047] The base station 1 is fixedly installed with a control console for controlling the base body 2, the pressure regulating assembly 3, the pacing assembly 4 and the circulation assembly 5.

[0048] At the beginning of the test, the operator horizontally pulls out the moving body and installs the multifunctional combined heart valve in the moving body, and then resets the moving body into the atrial simulation area 21 and the arterial simulation area 23 for testing. Then the operator opens the electromagnetic valve 26 to control a certain amount of dextran solution in the pressure tank 32 to enter the atrial simulation area 21. During the process of the dextran solution entering the atrial simulation area 21, the operator controls the telescopic stand 31 to drive the pressure tank 32 to move up and down, so as to control the pressure fluctuation of the dextran solution entering the atrial simulation area 21, thereby simulating the pressure fluctuation of the venous blood returning to the heart caused by breathing, bone compression, body posture and heart contraction and relaxation in real time. After the dextran solution enters the atrial simulation area 21 for a certain period of time, the first pressure detector 25 detects the pressure value in the atrial simulation area 21 in real time to determine whether the multifunctional combined heart valve in the atrial simulation area 21 leaks.

[0049] Then the piston type air pump is started. The piston type air pump 41 is started to continuously switch to input air pressure and extract air negative pressure to the pressure increasing area 222, so that a pressure difference is generated between the atrial simulation area 21 and the ventricular simulation area 22, and the dextran solution in the atrial simulation area 21 enters the atrial simulation area 21.

[0050] After the dextran solution enters the ventricular simulation area 22, the operator controls the piston type air pump through the central control operation table on the base station 1 to input a small amount of air to the ventricular simulation area 22 for a small amount of pressure increase, so that the second pressure detector 43 detects whether the pressure in the ventricular simulation area 22 is stable, thereby simultaneously determining whether the multifunctional combined heart valve in the atrial simulation area 21 and the arterial simulation area 23 leaks.

[0051] After the multifunctional combined heart valve is tested for leakage in the arterial simulation area 23, the operator increases the amount of air input or extracted by the piston air pump, so that there is a pressure difference between the ventricular simulation area 22 and the arterial simulation area 23, and then the dextran solution enters the arterial simulation area 23.

[0052] During this process, the first pressure detector 25 and the second pressure detector 43 can also display the pressure difference between the atrial simulation area 21 and the ventricular simulation area 22, so that at the moment when the pressure value in the atrial simulation area 21 decreases, the transvalvular pressure difference of the blood can be reflected according to the instantaneous difference between the first pressure detector 25 and the second pressure detector 43.

[0053] After the dextran solution enters the arterial simulation area 23 through the first liquid pipe 51 and enters the recovery box 52, the dextran solution is transported again to the pressure tank 32 through the reflux pump 54 and the second liquid pipe 53 for recycling.

[0054] In this way, the detection of whether the multifunctional combined heart valve leaks and the transvalvular pressure difference is completed.

[0055] It needs to be emphasized again that since the multifunctional combined heart valve is a combination of various components or materials with different functions, the performance of each multifunctional combined heart valve is different, and the pressure of the dextran solution entering the atrial simulation area 21 and the pressure difference between the atrial simulation area 21, the pulsation simulation area and the ventricular simulation area 22 can be actively adjusted and controlled in the embodiment of the disclosure, therefore, the embodiment of the disclosure is more suitable for testing multifunctional combined heart valves with different performances.

[0056] Finally, it needs to be emphasized that in the embodiment of the disclosure, whether the artificial heart valve 27 leaks is tested by whether the pressure value displayed by the first pressure detector 25 and the second pressure detector 43 in real time is the same as the standard pressure value under dynamic pressure, and the standard pressure value is pre-set.

[0057] Embodiment two; the embodiment of the disclosure is established on the basis of embodiment one and only records the differences from embodiment one, and the same parts are not described again.

[0058] In the embodiment of the disclosure, the telescopic table 31 includes a base plate and a hydraulic telescopic rod, the extension and retraction of the hydraulic telescopic rod can drive the base plate and the pressure tank 32 to move up and down, and then the pressure in the atrial simulation area 21 can be actively controlled.

[0059] In the process of detecting whether the multifunctional combined heart valve leaks in the process of dextran solution entering the atrial simulation area 21, at this time, the piston air pump 41 has not started, the electromagnetic valve 26 is in the normal open state, the operator can control the hydraulic telescopic rod to extend, thereby controlling the pressure increase in the atrial simulation area 21, and further detecting whether the multifunctional combined heart valve leaks and the pressure bearing performance.

[0060] The present embodiment can adjust the pressure of dextran solution entering at any time in the process of testing leakage in the atrial simulation area 21, thereby improving the flexibility during use and facilitating testing.

[0061] Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
