The water storage tank 4 is arranged on the upper mounting platform of the mounting frame, and the liquid level sensor 5 is arranged in the water storage tank 4. The liquid level sensor 5 is used to monitor the water level in the water storage tank 4, so as to ensure the water amount in the water storage tank 4, thereby ensuring that the water self-weight pressurization pressure meets the requirements of YY / T0500 “Cardiovascular Implant Vascular Prosthesis Tubular Vascular Graft and Vascular Patch” standard.

[0031] As shown in Figure 1 and Figure 2 , the water outlet assembly includes a water outlet pipe 6 and a one-way valve 7. One end of the water outlet pipe 6 is located in the interior of the water storage tank 4, and the other end is located on the middle mounting platform of the mounting frame and connected with the water seepage detection seat 8. The one-way valve 7 is arranged on the water outlet pipe 6 and used to control the opening and closing of the water outlet pipe 6.

[0032] As shown in Figure 1 and Figure 2 , the test assembly includes a water seepage detection seat 8, a pressure gauge 10, a water seepage detection cover 11, and a measuring cup 13. The water seepage detection seat 8 is arranged on the middle mounting platform of the mounting frame. The water seepage detection seat 8 has a shaft-shaped connecting segment 81 and a circular pie-shaped detection segment 82. A water conveying flow channel 83 is arranged in the water seepage detection seat 8 along the axis and penetrates the connecting segment 81 and the detection segment 82. One end of the water conveying flow channel 83 is in communication with the other end of the water outlet pipe 6, and the other end is provided with a first connecting pipe 9 protruding from the detection segment 82. The pressure gauge 10 is arranged on the water seepage detection seat 8 and used to monitor the pressure in the water conveying flow channel 83. The water seepage detection cover 11 is circular pie-shaped and detachably arranged on the detection segment 82. A second connecting pipe 12 is arranged on the water seepage detection cover 11 at the center thereof. The inner diameter of the second connecting pipe 12 is equal to the outer diameter of the first connecting pipe 9. The measuring cup 13 is arranged on the mounting frame and below the other end of the second connecting pipe 12. The diameter of the first connecting pipe 9 is preferably 1 cm2.

[0033] In the embodiment, a plurality of first mounting holes are arranged on the end surface of the detection segment 82 in the circumferential direction. A plurality of second mounting holes are arranged on the end surface of the water seepage detection cover 11 in the circumferential direction. Each second mounting hole is provided with a corresponding first mounting hole. Each second mounting hole is provided with a fixing member. The outer wall of each fixing member and the inner wall of the corresponding first mounting hole and second mounting hole are respectively provided with external threads and internal threads which are engaged with each other.

[0034] In the embodiment, the diameter of the detection section 82 is equal to the diameter of the water permeation detection cover 11.

[0035] In the embodiment, the set range of the pressure gauge 10 is 16KPa±0.3KPa, so that the water pressure meets the requirements of YY / T0500 Cardiovascular Implant Vascular Prosthetic Tubular Vascular Grafts and Vascular Prostheses standard.

[0036] In the embodiment, the control module is connected with the water pump 3, the liquid level sensor 5 and the pressure gauge 10, and the control module is used for receiving the signals of the liquid level sensor 5 and the pressure gauge 10 to control the water pump 3 to be opened or closed.

[0037] When the water permeation detection cover 11 is fixed on the detection section 82, the medical textile sample is tightly fixed between the water permeation detection cover 11 and the detection section 82.

[0038] Then, the water permeation detection cover 11 is fixed on the detection section 82 through the cooperation of the fixing member and the first mounting hole and the second mounting hole, so that the medical textile sample is tightly fixed between the water permeation detection cover 11 and the detection section 82.

[0039] Then, the control module controls the water pump 3 to run, so that the water pump 3 cooperates with the water inlet pipe 2 to transport the purified water in the water supplement tank 1 to the water storage tank 4, and the liquid level sensor 5 in the water storage tank 4 detects the water level in the water storage tank 4, so that the water level is located between the high position and the low position, thereby preliminarily determining and maintaining the pressure in the water outlet pipe 6.

[0040] Then, the one-way valve 7 is opened, and the purified water is allowed to enter the water delivery channel 83 inside the water penetration detection seat 8 through the water outlet pipe 6. At this time, the pressure gauge 10 detects the pressure in the water delivery channel 83, so that the water pump 3 is controlled by the control module to adjust the water level in the water storage tank 4, thereby ensuring that the water pressure in the water delivery channel 83 meets the requirements of YY / T0500 "Cardiovascular implant vascular prosthetic tubular vascular graft and vascular patch" standard, that is, the water pressure is within the range of 16KPa±0.3KPa, so that the pressure in the water outlet pipe 6 is further determined and maintained. Specifically, when the water pressure is lower than the range of 16KPa±0.3KPa, the control module controls the water pump 3 to run to supplement water; when the water pressure is higher than the range of 16KPa±0.3KPa, the control module controls the water pump 3 to stop running and stop supplementing water. Therefore, the water level can be automatically supplemented and controlled by high and low positions, so that the pressure at the bottom of the water storage tank 4 is effectively maintained.

[0041] Finally, the water flow passes through the first connecting pipe 9 and the second connecting pipe 12 to perform the water penetration test on the textile sample. Specifically, after the water flow from the other end of the second connecting pipe 12 is stable and uniform, the measuring cup 13 is placed below the other end of the second connecting pipe 12, and timing is started at the same time. When the timing is 60S±1S, the one-way valve 7 is closed, the measuring cup 13 is taken out, and the reading of the measuring cup 13 is read, that is, the water penetration value of the textile sample is obtained.

[0042] Effects of the embodiment

[0043] The automatic water supply pressure maintaining medical textile water penetration detection mechanism according to the present application is aimed at placing the medical textile between the detection section of the water penetration detection seat and the water penetration detection cover, and then opening the one-way valve to perform the water penetration test by the water self-weight pressurization method. Because the water supplement assembly can automatically supplement water into the water storage tank, and the control module can control the water supplement assembly to supplement water through the signals provided by the liquid level sensor and the pressure gauge, thereby adjusting the water pressure, the present application can avoid the problems of manual water supply and unstable pressure, so that the present application has high efficiency and strong stability when in use.

[0044] The above embodiment is a preferred case of the present application and does not limit the protection scope of the present application.
