A manufacturing device for a filter membrane for detecting Schistosoma haematobium eggs

Abstract

The present invention provides a manufacturing device for a filter membrane for detecting Schistosoma haematobium eggs, belonging to the technical field of prevention and control of parasitic diseases. The manufacturing device for the filter membrane for detecting Schistosoma haematobium eggs is composed of a temperature control switch 1, a cylindrical blade 3, a heating device 2, a spring 6 and a depressible handle 4. Compared with the prior art, the device can bond the edges of a nylon filter screen into a whole circle, making the edges clear, and during use, it will not cause wire breakage or wire running due to the inability to fix the edges of the filter screen, resulting in uneven local pore sizes of the filter screen, thereby affecting the accuracy of filtering Schistosoma haematobium eggs.

Description

Technical Field

[0001] A manufacturing device for a filter membrane for detecting eggs of Schistosoma haematobium belongs to the technical field of prevention and control of parasitic diseases. Background Art

[0002] Schistosoma haematobium lives in the vesical veins and is mainly distributed in Africa, southern Europe and the Middle East. The eggs pass through the venous wall into the bladder and are excreted with urine. At present, the main method for detecting Schistosoma haematobium is to filter urine and detect the eggs under a microscope. The filter membrane used is a monofilament nylon membrane, and in the process of use, the monofilament nylon membrane often has the problem of uneven pore size of the filter membrane due to the inability to fix the edge. Summary of the Invention

[0003] The purpose of the present invention is to provide a manufacturing device for a filter membrane for detecting eggs of Schistosoma haematobium.

[0004] The technical solution of the present invention: A manufacturing device for a filter membrane for detecting eggs of Schistosoma haematobium, which device is composed of a temperature control switch 1, a circular heating ring 2, a circular blade 3, a handle 4, a tabletop 5 and a spring 6;

[0005] The surface of the tabletop is covered with high-temperature resistant rubber (softening temperature greater than 300 degrees Celsius), and one end is connected with a fixed column with a hinge. The fixed column is connected to the handle 4 by a hinge. The middle of the handle 4 is connected to the circular blade 3 and the circular heating ring 2, and a spring is installed between the blade and the heating ring. Place the filter membrane to be processed between the circular heating ring 2 and the tabletop, press down the handle 4, the circular heating ring 2 starts to heat to between 220 - 250 degrees Celsius, the edge of the nylon filter membrane melts to form a circular whole, the temperature control switch 1 disconnects the circuit, continue to press down the handle 4, the circular blade 3 moves downward to cut the filter membrane; release the handle 4 to obtain a nylon filter screen with a fixed edge.

[0006] The inner diameter of the circular heating ring 2 is 11.5 or 23.5 mm, the outer diameter is 12.5 or 24.5, and the diameter of the circular blade 3 can be 13 and 25 mm. The material of the circular heating ring 2 is a heat-conducting body with a certain hardness (such as steel).

[0007] The beneficial effects of the present invention: Solve the problems that in the process of use, the monofilament nylon membrane often has wire running and wire breaking due to the inability to fix the edge, resulting in uneven pore size of the filter membrane. This device can bond the edge of the nylon filter screen into a whole circle, so as to keep the pore size of the filter membrane uniform and reduce the missed detection rate of Schistosoma haematobium urine.
