Abstract
The utility model relates to a purifying apparatus, particularly a medicine liquid filter for infusion. The convex ring on the base in the large mouth end of a funnel-shaped lower casing is connected with the circumference of a microporous filtering film, and the concave ring of the large mouth end of a funnel-shaped upper casing is butted with the convex ring of the lower casing which is used for positioning the microporous filtering film. The utility model is characterized in that a purifying layer which is made of the microporous filtering film is used as filtering medium; the medicine liquid filter is arranged in the channel before infusion enters human bodies. The purifying layer can completely remove pathogenic microparticles in infusion, which has no toxicity and no medium migration.
Description
This utility model relates to purifier, specifically a kind of transfusion liquid medicine filter.
The patient is when transfusion, and various microgranules, the dust of institute's disperse in the air will inevitably enter the blood of human body circulation with medicinal liquid by the induction part and the transfusion device of transfusion, and the distribution whole body may cause being detrimental to health.At present to human transfusion the time, the filter of usefulness is easy to self-dissolving as the chip of filter medium and comes off in infusion process, and causing more, multiparticulates enters blood of human body.In addition, also have and adopt the net of machinery braiding to make filter, cause filtration unclean because the pore-size distribution of these nets is unequal, microgranule still can pass through.People urgently wish to obtain high-quality, as not have the microgranule that causes a disease transfusion from the hope of health.
The purpose of this utility model provides a kind of reliable medical filtration device, and when being used for human transfusion, the dropping funnel that is added in transfusion device is interior or terminal, can remove the insoluble particle that jeopardizes health in the medicinal liquid fully.
The purpose of this utility model realizes by following measure: it comprises upper shell, lower house and microporous filter membrane purifying layer.Convex ring place (5) in infundibulate lower house (6) big opening end on the pedestal, the periphery of overlap joint microporous filter membrane (3), the spill ring place (4) of infundibulate upper shell (2) big opening end is docked on lower house (6) bulge loop (5) of putting microporous filter membrane (3).
This filter uses microporous filter membrane, because the aperture of microporous filter membrane is very little, and is evenly distributed, can remove pathogenic microgranule in the liquid fully by filtration.
Characteristics of the present utility model are: the purifying layer made from microporous filter membrane is as filtering medium, liquid medicine filter is installed in transfusion enters in the passage before the human body, and purifying layer can be removed the pathogenic microgranule in the transfusion fully, and avirulence, no medium move.
The utility model has the advantages that: 1, simple in structure, easy to install and use, the original structure of not destroying transfusion device; 2, can leach pathogenic microgranule in the medicinal liquid effectively, cause the secondary disease when preventing to infuse.
Accompanying drawing is a structural representation of the present utility model.
The upper and lower casing of liquid medicine filter (2,6) can adopt non-toxic plastic etc. to make.
Use of the present utility model is as follows: the liquid outlet (7) and the liquid injecting piece of lower house (6) are connected, and the inlet (1) of upper shell (2) and the end of conduit are connected.Medicinal liquid is introduced by the inlet (1) of upper shell (2), because self pressure of medicinal liquid, medicinal liquid is by microporous filter membrane purifying layer (3), and scavenging solution is flowed out by the liquid outlet (7) of lower house (6).Upper and lower casing (2,6) big opening end is closely to peg graft.
Claims (1)
1, a kind of transfusion liquid medicine filter, comprise upper shell, lower house and microporous filter membrane purifying layer, it is characterized in that the convex ring place (5) on the pedestal in infundibulate lower house (6) big opening end, the periphery of overlap joint microporous filter membrane (3), the spill ring place (4) of infundibulate upper shell (2) big opening end is docked on lower house (6) bulge loop (5) of putting microporous filter membrane (3).
