Air filter for infusion apparatus

Abstract

The invention relates to an air filter for an infusion set, which includes an upper casing, a lower casing and a filter membrane purification layer, and is characterized in that the upper casing is in the shape of an inverted funnel, a pipe joint is provided at the upper end, and an inner convex ring is provided at the lower end port The base and the lower shell are in the shape of a net cover, fastened on the base of the convex ring in the upper shell, and the filter membrane purification layer is a glass fiber membrane, which is sandwiched between the convex ring base in the upper shell and the net cover of the lower shell. The upper and lower casings of the present invention are simple in structure, reliable in connection, and beautiful in appearance. The glass fiber membrane is used as the filter membrane purification layer, with low cost and good filtering and purification effects, and is an ideal air filter for infusion sets.

Description

technical field [0001] The invention relates to a medical device, in particular to an air filter for an infusion set. Background technique [0002] We know that infusion and blood transfusion sets are commonly used medical devices. In the air, there are particles and pathogenic microorganisms of various sizes scattered, such as Mycobacterium tuberculosis, pneumococcus, influenza virus, polio, etc. On the surface of dust particles, they can survive in the air for a period of time. During the clinical intravenous infusion, the air in the ward enters the infusion container through the air intake pipe, so that the particles and pathogenic microorganisms enter the liquid medicine with the air, and the liquid medicine is polluted. , when it enters the human body, it will cause harm to the human body. At present, in clinical intravenous infusion and blood transfusion, according to the requirements of national standards, the matching air filter should be used. Existing filters ge...

AI Technical Summary

Problems solved by technology

Due to the unreasonable structure and connection of the upper and lower shells, the selected filter membrane purification layer is also relatively complicated, which makes the cost of the existing air filter high, and the filtering and purification effects are not good.
