Problems solved by technology
Conventional precision liquid medicine filters are generally composed of upper and lower casings and a flat filter membrane in the middle. Due to the limitation of the filter membrane, the infusion flow rate of the precision filter infusion set is relatively low. In case of emergency rescue, its Significantly insufficient infusion flow rate

Embodiment 1
[0018] Such as Figure 1-2 As shown, the high-efficiency precision liquid medicine filter of the present invention includes a casing 2 and a filter membrane in the casing 2, and the upper and lower ends of the casing 2 are integrally formed with a liquid inlet joint and a liquid outlet joint, wherein the liquid inlet joint and the upper The conduit 1 is fixedly connected in a conventional manner, the liquid outlet joint is fixedly connected with the downcomer 9 in a conventional manner, and an exhaust port is formed on the upper end of the casing 2, and an exhaust film 3 is fixed in the exhaust port by gluing; The upper part of the cavity in 1 is fixed with an upper holder 4 matching the corresponding position and size of the inner wall of the housing 1 by gluing. The matching lower holder 7, upper holder 4, and lower holder 7 divide the cavity in the shell 1 into an upper liquid inlet cavity 1.1, a middle filter cavity 1.2 and a lower liquid outlet cavity 1.3; the upper holde...

The invention discloses a high-efficiency precise liquid medicine filter. The high-efficiency precise liquid medicine filter comprises a shell and filtering membranes in the shell, wherein a liquid inlet connector and a liquid outlet connector are integrally formed at the upper end and the lower end of the shell, an exhaust port is further formed in the upper end of the shell, and an exhaust membrane is fixed in the exhaust port; and an upper fixer is fixed at the upper part of a cavity in the shell, a lower fixer is fixed at the lower part of the cavity in the shell, a plurality of liquid inlet holes for communicating an upper liquid inlet cavity with a middle filtering cavity are formed in the upper fixer, and the filtering membranes are a plurality of tubular filtering membranes. According to the invention, an existing flat filtering membrane is replaced by the tubular filtering membranes, so that the filtering contact area of liquid medicines is greatly increased under the condition of the same volume, and the filtering rate and the infusion flow rate can be improved by a conventional infusion operation.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-efficiency precision liquid medicine filter. Background technique [0002] The precision medicinal liquid filter is mainly used in the filtration of medicinal liquid in clinical infusion sets, and its filtration rate of filtering out particles above 5 μm in the medicinal liquid is not less than 90%. Conventional precision liquid medicine filters are generally composed of upper and lower casings and a flat filter membrane in the middle. Due to the limitation of the filter membrane, the infusion flow rate of the precision filter infusion set is relatively low. In case of emergency rescue, its The infusion flow rate is obviously insufficient. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a high-efficiency precision liquid medicine filter with reasonable structural ...
