[0002] Non-alcoholic steatohepatitis, also known as metabolic steatohepatitis, is a clinical syndrome with pathological changes similar to alcoholic hepatitis but without a history of excessive alcohol consumption. It is prone to occur in middle-aged people, especially overweight and obese individuals. Non-alcoholic steatohepatitis is closely related to metabolic disorders such as obesity, insulin resistance, type 2 diabetes, and hyperlipidemia. Its main feature is macrovesicular steatosis of hepatocytes accompanied by hepatocyte damage and inflammation. In severe cases, it can develop into liver cirrhosis. Anti-nonalcoholic steatohepatitis raw materials are used to prepare anti-nonalcoholic steatohepatitis finished drugs. During the processing of anti-nonalcoholic steatohepatitis raw materials, multiple filtrations through filters are required. Due to high filtration requirements, it is necessary to detect the integrity of the filters.

[0003] In the prior art, for the detection of filter plates in filters, tests are usually carried out through air, smoke, fluids, etc., by methods such as allowing the test substance to pass through the filter holes and discharging it or detecting the pressure during the test of the test substance.

[0050] A second spring 27 is sleeved on the limiting rod 23. Two ends of the second spring 27 are respectively fixedly connected to the collecting pipe 20 and the limiting rod 23.

[0051] In an embodiment of the present invention, the reset of the sealing plug 21 is ensured by the provided first spring 26, and the stable connection between the limiting block 24 and the limiting grooves 25 is ensured by the provided second spring 27.

[0052] As an alternative embodiment, the first seal includes a groove 28 formed on the top cover 12. The filter plate 4 to be tested is fixedly connected in the support ring 29. The groove 28 is adapted to the support ring 29.

[0053] In an embodiment of the present invention, the support ring 29 is adapted to the groove 28, and the support ring 29 is snap-fitted into the groove 28 to realize the connection between the support ring 29 and the top cover 12.

[0055] In one embodiment of the present invention, the rubber membrane 30 has elasticity. When the groove 28 is connected to the support ring 29, the support ring 29 will squeeze the rubber membrane 30 so that it fills the gap between the groove 28 and the support ring 29, ensuring the sealing effect.

[0056] As an alternative embodiment, the second seal includes a sealing ring 31 fixedly connected to the mouth of the collection tube 20. A plurality of connecting rings 32 are fixedly connected to the bottom end of the filter plate 4 to be tested.
