Problems solved by technology

Cutting-edge technology is gradually developing heavy ion microporous membranes. Due to the penetration of the membrane material after the acceleration of heavy ions and electrons, the thickness of the membrane material is only about 5 microns, and the strength of the membrane material is extremely low. When filtering the liquid medicine, the heavy ion microporous membrane Assembled in the free space of the upper and lower shells or placed on the mesh plastic support, the filter membrane is easily broken by the liquid flow with a large infusion flow rate in case of emergency infusion, resulting in failure of the liquid medicine filtration

Abstract

The invention discloses an efficient filter, and relates to the technical field of medical instruments. The efficient filter comprises a first coating layer, a second coating layer and a heavy ion micro-porous membrane layer. The first coating layer and the second coating layer form a through cavity for accommodating the heavy ion micro-porous membrane layer. According to the efficient filter, the first coating layer and the second coating layer are arranged on the inner side and the outer side of the heavy ion micro-porous membrane layer respectively, the efficient filter is used for an infusion and blood transfusion instrument, the heavy ion micro-porous membrane is not prone to being broken by liquid flow during rapid infusion in emergency rescue, the phenomenon that liquid medicine filtration fails is avoided, and the safety of infusion filtration is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a high-efficiency filter. Background technique [0002] Precision liquid medicine filters are mainly used in the filtration of liquid medicine in clinical infusion sets. Conventional precision liquid medicine filters are made of fiber membranes, and their filtration efficiency is low. Cutting-edge technology is gradually developing heavy ion microporous membranes. Due to the penetration of the membrane material after the acceleration of heavy ions and electrons, the thickness of the membrane material is only about 5 microns, and the strength of the membrane material is extremely low. When filtering the liquid medicine, the heavy ion microporous membrane Assembled in the free space of the upper and lower shells or placed on the mesh plastic support, the filter membrane is easily broken by the liquid flow with a large infusion flow rate in case of emerge...
