Abstract

The invention discloses a detachable filter for an infusion apparatus. The filter comprises an upper catheter and a lower catheter which are used for being connected with an infusion pipe; the filtercomprises an upper shell and a lower shell which are detachably connected; the upper shell is internally provided with a primary filtering membrane, and a detachable secondary filtering membrane is sandwiched between the upper shell and the lower shell; several exhaust holes are formed in the top of the upper shell; the primary filtering membrane is a rough filtering membrane and can filter out particles with the diameter of 20 microns or above in medicine liquid; the secondary filtering membrane is a precise filtering membrane and can filter out particles with the diameter between 5-20 microns in the medicine liquid. The filter for infusion has the advantages that the filtering efficiency is high, the filtering effect is good, and multiple using requirements can be met.

Description

technical field [0001] The invention relates to a filter for a detachable infusion set, which belongs to the field of medical supplies. Background technique [0002] Because there are a large amount of various particles in the medicinal liquid, the infusion set is provided with a medicinal liquid filter. The liquid medicine filter used in general infusion sets intelligently filters particles with a diameter of more than 20 microns, and the filter membrane used is a coarse filter membrane. The number of particles with a diameter of 5 to 20 microns in the liquid medicine is the largest and the most harmful. Therefore, an infusion set that uses a filter membrane that can filter particles with a diameter of more than 5 microns is called a precision filter infusion set, but the filter holes of the precision filter are very small, which affects the flow rate and flow rate of the infusion. [0003] The invention application with the application number 200910253590.8 discloses a d...
