Abstract

The invention discloses an automatic liquid-stopping nuclear pore filter membrane for precision transfusion and a preparation method thereof. The preparation method comprises the following steps: irradiating thick polyester film with particles produced by an accelerator, and heating it at 55-80°C, 6.5-8.0mol / Etch in L sodium hydroxide aqueous solution for 3-60 minutes; wash in 55-80°C, 0.5-1mol / L sodium hydroxide aqueous solution; then wash in deionized water; in 60°C 80°C modification solution, first ultrasonic Soak for 3-10 minutes, then stop ultrasonic soaking for 15-40 minutes, continue ultrasonic soaking for 3-10 minutes; wash in deionized water; dry at 40-70°C, and then make a nuclear pore filter membrane for precision infusion with automatic liquid stop , the method of the present invention is simple, the prepared film is super hydrophilic, the water contact angle is less than 30°, and the liquid stop height is 1.8-3.0 meters.

Description

technical field [0001] The invention belongs to the technical field of large infusion precision filtration, and in particular relates to a preparation method of an automatic liquid-stopping nuclear pore filter membrane for precision infusion. technical background [0002] Infusion therapy originated at the end of the nineteenth century and has a long history. Because of its simple and convenient operation, remarkable curative effect and fast characteristics, it has become one of the indispensable means and methods in modern clinical treatment since the 1930s, and has an extremely important position in modern clinical practice. [0003] In clinical infusion practice, whether it is an ordinary filter infusion set or a precision liquid filter infusion set, nurses need to pay special attention to avoid the phenomenon that the liquid drops empty into the Murphy's dropper and the phenomenon that the liquid drops out of the Murphy's dropper. The dropper will need secondary exhaust...
