Abstract
The utility model discloses a self-exhausting medicine liquid filter. The self-exhausting medicine liquid filter comprises a liquid inlet shell, an exhaust hole which is formed in the liquid inlet shell, an exhaust film and a liquid outlet shell. A liquid outlet is formed in the upper portion of the liquid outlet shell. The liquid outlet shell is connected with the liquid inlet shell through a filtering membrane. A supporting piece is arranged between the filtering membrane and the liquid outlet shell. The supporting piece is a plane supporting piece. The supporting piece is a protruded plane, wherein the liquid outlet shell protrudes inward to form the protruded plane, and the protruded plane supports the filtering membrane. The self-exhausting medicine liquid filter which reduces probability that tiny bubbles flow to a vein of a human body aims to be provided.
Description
Technical field
This utility model relates to a kind of filter, relates in particular to a kind of from the aerofluxus liquid medicine filter.
Background technology
At present in the transfusion device that hospital uses at home, the filtration and the aerofluxus of medicinal liquid roughly there is following several version:
First kind: as shown in Figure 1, medicinal liquid enters in the housing by the suitable for reading of feed liquor shell 1, air in the medicinal liquid is discharged by exhaust membrane 3 and steam vent 2, medicinal liquid is through the filtration of filter membrane 4, outlet from fluid shell 5 bottoms at last flows to human vein, 6 for supporting the narrow muscle or the small column of filter membrane, and 7 is the bossing of fluid shell outside; The problem that this structure exists is that the most of air in the medicinal liquid is all discharged by exhaust membrane and steam vent, is attached to narrow muscle that supports filter membrane or the micro-bubble on the small column flows into human vein together with medicinal liquid probability on a small quantity but can not get rid of.
Second kind: as shown in Figure 2, structure and Fig. 1 among Fig. 2 are basic identical, it is that outlet from fluid shell top flows to human vein that difference is by filtered medicine liquid, second kind of structure compared with first kind improvement slightly, part is attached to the narrow dish or the micro-bubble on the small column that support filter membrane and is agglomerated into the air pocket continuation by exhaust membrane and steam vent discharge, however still can not get rid of micro-micro-bubble flows into human vein together with medicinal liquid probability.
The utility model content
This utility model embodiment technical problem to be solved is, provide a kind of reduced micro-bubble flow to the human vein probability from the aerofluxus liquid medicine filter.
Described from the aerofluxus liquid medicine filter, comprise the feed liquor shell and be arranged on steam vent and exhaust membrane on the described feed liquor shell, also comprise the fluid shell, described fluid shell top is provided with liquid outlet, described fluid shell is connected with described feed liquor shell by filter membrane, be provided with support member between described filter membrane and the described fluid shell, described support member is a flat support.
Described support member be the fluid shell to inner convex plane, described crowning supports described filter membrane.
Implement this utility model embodiment, have following beneficial effect:
In the present embodiment part of fluid shell projection is arranged on the inside of housing, so both made that the housing profile was smooth attractive in appearance, the design and the difficulty of processing of technological equipment have been alleviated again, and the part of projection has played the effect of supporting filter membrane, the support surface of projection is the plane, this is the improved key of transfusion effect, micro-bubble ratio in the medicinal liquid is easier to get into air pocket, bubble breaks, air is discharged from steam vent by exhaust membrane, thereby greatly reduces the probability that micro-bubble flows to human vein.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, this utility model is described in further detail below in conjunction with accompanying drawing.
Present embodiment is a kind of from the aerofluxus liquid medicine filter, comprise feed liquor shell 1 and be arranged on steam vent 2 and exhaust membrane 3 on the feed liquor shell 1, also comprise fluid shell 5, fluid shell 5 tops are provided with liquid outlet 6, fluid shell 5 is connected with feed liquor shell 1 by filter membrane 4, fluid shell 5 inside are provided with projection, and as the support member 7 of filter membrane 4, support member 7 surfaces are the plane; Medicinal liquid is from the housing that enters suitable for reading of feed liquor shell 1, and the air in the medicinal liquid is discharged from steam vent 2 by exhaust membrane 3, when rising to the outlet on fluid shell 5 tops through filter membrane 4 filtered medicine liquid liquid levels, flows to human vein with regard to beginning from the bottom of outlet.
In the present embodiment part of fluid shell projection is arranged on the inside of housing, so both made that the housing profile was smooth attractive in appearance, the design and the difficulty of processing of technological equipment have been alleviated again, and the part of projection has played the effect of supporting filter membrane, the support surface of projection is the plane, this is the improved key of transfusion effect, micro-bubble ratio in the medicinal liquid is easier to get into air pocket, bubble breaks, air is discharged from steam vent by exhaust membrane, thereby greatly reduces the probability that micro-bubble flows to human vein.
Above disclosed only is a kind of preferred embodiment of this utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalent variations of being done according to this utility model claim still belongs to the scope that this utility model is contained.
