Abstract
The utility model discloses a liquid medicine filter comprising a liquid inlet end cover and a liquid outlet end cover which are clamped into a whole, wherein the liquid inlet end cover is provided with a liquid inlet tube; the liquid outlet end cover is provided with a liquid outlet tube; a filter membrane is arranged between the liquid inlet end cover and the liquid outlet end cover and used for dividing a container defined by the liquid inlet end cover and the liquid outlet end cover into a liquid inlet cavity and a liquid outlet cavity; the liquid inlet tube is communicated with the liquid inlet cavity; the liquid outlet tube is communicated with the liquid outlet cavity; and the outer surfaces of the liquid inlet tube and the liquid outlet tube are respectively provided with a plurality of annular protrusions. Due to the arrangement of the annular protrusions respectively arranged on the outer surfaces of the liquid inlet tube and the liquid outlet tube, the liquid inlet tube and the liquid outlet tube can be connected more firmly when being connected with a transfusion hose and a transfusion needle, so that liquid leakage at a connection part is avoided.
Description
Technical field
This utility model relates to a kind of for the liquid medicine filter on disposable transfusion device.
Background technology
When giving patient infusion, liquid medicine filter is arranged on disposable transfusion device, in order to the particulate matter more than 5 μ m in the filtering medicinal liquid, these transfusion devices are when clinical use, the phenomenon that infusion tube, transfusion needle and liquid medicine filter cooperation place leakage often occur, particularly now use clinically the many of remaining needle, when again coordinating with liquid medicine filter after transfusion needle is taken off, the phenomenon of leakage more easily appears in transfusion needle and liquid medicine filter junction.
Summary of the invention
The technical problems to be solved in the utility model is to provide the liquid medicine filter that a kind of and transfusion device junction are not easy leakage.
For solving the problems of the technologies described above, this utility model comprises and clamps feed liquor end cap and the fluid end cap that is integrated, liquid feeding end covers and is provided with feed tube, liquid outlet covers and is provided with drain pipe, between feed liquor end cap and fluid end cap, filter membrane is installed, the cavity volume that filter membrane surrounds feed liquor end cap and fluid end cap is divided into admission chamber and goes out sap cavity, and feed tube is communicated with admission chamber, drain pipe with go out sap cavity and be communicated with, its construction features is that to be respectively equipped with many rings on the outer surface of described feed tube, drain pipe protruding.
After adopting said structure, protruding by at feed tube and drain pipe outer surface, ring being set respectively, with infusion tube, when transfusion needle is connected, can make both connections more fastening, prevent the junction leakage.
Axially evenly that three rings are set is protruding at interval along it for described feed tube, strengthens the sealing effectiveness of itself and infusion tube junction.
Axially evenly that three rings are set is protruding at interval along it for described drain pipe, strengthens the sealing effectiveness of itself and transfusion needle junction.
Its inlet end of the outer radial of described feed tube reduces gradually; Its liquid outlet end of the outer radial of described drain pipe reduces gradually.
Described feed liquor end cap and fluid end cap junction are set with the ring set with the gap sealing of both junctions.
Described liquid outlet covers and is provided with the stepped hole that runs through its sidewall,, is provided with on step surface the two separated hydrophobic permeable membranes in hole greater than the diameter away from the hole that goes out the sap cavity side near the diameter in the hole that goes out the sap cavity side.
Description of drawings
Below in conjunction with the drawings and the specific embodiments, this utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, liquid medicine filter comprises and clamps feed liquor end cap 1 and the fluid end cap 2 that is integrated, and the outer surface of feed liquor end cap 1 and fluid end cap 2 junctions is set with the ring set 9 with the gap sealing of both junctions.Between feed liquor end cap 1 and fluid end cap 2, filter membrane 5 is installed, the periphery of filter membrane 5 is compressed by feed liquor end cap 1 and fluid end cap 2, the cavity volume that filter membrane 5 surrounds feed liquor end cap 1 and fluid end cap 2 is divided into admission chamber 6 and goes out sap cavity 7, be connected with feed tube 3 on feed liquor end cap 1, feed tube 3 is communicated with admission chamber 6, be connected with drain pipe 4 on fluid end cap 2, drain pipe 4 with go out sap cavity 7 and be communicated with.The external diameter of feed tube 3 reduces to the inlet end gradually from itself and feed liquor end cap 1 link, i.e. the frustum of 3 one-tenth hollows of feed tube; The external diameter of drain pipe 4 reduces to the liquid outlet end gradually from itself and fluid end cap 2 links, i.e. the frustum of 4 one-tenth hollows of drain pipe.Feed tube 3 and drain pipe 4 all are the frustum of hollow, and convenience is connected with infusion tube, transfusion needle.The outer surface of feed tube 3, drain pipe 4 along its axially respectively evenly the interval three rings protruding 8 are set, encircling protruding 8 is structure as a whole with feed tube 3 and drain pipe 4, protruding 8 position changes of ring when preventing from using, by at feed tube 3 and drain pipe 4 outer surfaces, ring protruding 8 being set respectively, with infusion tube, when transfusion needle is connected, can make the junction more fastening, prevent the junction leakage.
The above is only preferred embodiment of the present utility model, is not limited to this utility model.Previous embodiment has been described in detail this utility model, and for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.In every case within inventive concept scope of the present utility model, any modification of making, be equal to replacement, improvement etc., within all being included in protection domain of the present utility model.
