Abstract
The utility model discloses a vertical-type polypropylene transfusion bag with a double valve clamp joint-type combination cover comprising two parts, namely a double valve combination cover and a vertical-type polypropylene transfusion bag. The double valve combination cover is constituted by an outer cover, an inner cover and a gasket. The gasket can be disposed in the outer cover, and the inner cover can be combined with the outer cover together in a clamped manner to form a double valve combination cover. The vertical-type polypropylene transfusion bag and the double valve combination cover can be welded together by two welding rings. The utility model is advantageous in that the vertical-type polypropylene transfusion bag provided in the utility model adopts the design of double openable covers compared to the traditional transfusion packages, thereby the medicine feeding function and the transfusion function can be independent; a fully-enclosed transfusion can be realized by using the vertical-type polypropylene transfusion bag with an ellipse-shaped cross section, and air intake is not required during the transfusion, thereby the cross-contamination during the use can be prevented, the open is convenient, the structure as well as the production technology is simple, and the production costs are low.
Description
Technical field
This utility model relates to a kind of vertical type polypropylene transfusion bag with bivalve plug-in composite cover.
Background technology
The composite cover that existing transfusion bag adopts usually is made up of three parts: inner cap, enclosing cover and place inner cap and enclosing cover between pad (like the polyisoprene pad).After in factory, pouring into bottle or bag to medicinal liquid, again at bottle or bag mouth heat seal seal combination lid; During the clinical use of medical worker, draw back or pry open the seal cover top earlier, pass through pad and inner cap with the puncture of dosing pin then, medicinal liquid is injected carry out the medicinal liquid preparation in bottle or the bag, after medicinal liquid prepared, the puncture of reuse resin pin was passed through pad and inner cap to patient infusion.The shortcoming of this transfusion package is: plastic infusion bag can not self-constriction, can not realize the total enclosing transfusion, and dosing and the shared opening cover of transfusion are opened effort, and be prone to cause liquid medicine contamination.
The utility model content
The purpose of this utility model is to provide a kind of vertical type polypropylene transfusion bag with bivalve plug-in composite cover.
This utility model is realized through following technical scheme:
The vertical type polypropylene transfusion bag of band bivalve plug-in composite cover comprises bivalve composite cover 1 and vertical type polypropylene transfusion bag 2 two parts, and bivalve composite cover 1 is made up of enclosing cover 7, inner cap 8, pad 3.It is characterized in that: it is two cylindrical open valves 6 that enclosing cover 7 extends upward; Cylindrical open valve 6 closely is connected with infusion port 5 with dosing mouth 4; The diameter of dosing mouth 4 extends to composite cover welding ring 9 downwards greater than the diameter of infusion port 5, and composite cover welding ring 9 tops are provided with enclosing cover buckling groove 13; 8 one-tenth convexs of inner cap, the centre is provided with inner cap buckling groove 12, and inner cap 8 enclosing covers 7 are connected through snap fit; 3 one-tenth circular triangles of pad are embedded between enclosing cover 7 and the inner cap 8 and are combined into composite cover; Composite cover is through the composite cover welding ring 9 of enclosing cover 7 and the vertical type polypropylene transfusion bag of the transfusion bag welding ring 10 welding formation band bivalve plug-in composite covers of vertical type polypropylene transfusion bag 2.
Said open valve 6 is cylindrical.
Said pad 3 is " circular triangle " structure, is equipped with matrix circular hole 14 up and down, is " 8 word " shape.
Said vertical type polypropylene transfusion bag 2 openings have transfusion bag welding ring 10; Enclosing cover 7 lower ends have composite cover welding ring 9; Be used for and 10 welding of transfusion bag welding ring; Enclosing cover 7 closely links together with vertical type polypropylene transfusion bag 2, and the cross section of said vertical type polypropylene transfusion bag 2 is oval.
The advantage of this utility model is, compares with traditional transfusion package, and this utility model adopts two opening cover designs; With dosing, two functions of transfusion independently, be oval-shaped vertical type polypropylene transfusion bag through cross section, need not advance air during transfusion; Can realize the total enclosing transfusion; Avoided the cross-contamination of use, easy to use, structure and production technology are simple, production cost is lower.

The specific embodiment
Embodiment 1:
Enclosing cover 7 parts of bivalve composite cover 1 are used the polypropylene granules single injection-molded: cylindrical open valve 6, composite cover welding ring 9; Make pad 3 with polyisoprene; With the special-purpose pellet single injection-molded of polypropylene inner cap 8.
Pad 3 is put into enclosing cover 7; Inner cap 8 is combined to form bivalve composite cover 1 through snap fit and enclosing cover 7, at last bivalve composite cover 1 and vertical type polypropylene transfusion bag 2 is formed the vertical type polypropylene transfusion bag of band bivalve plug-in composite cover through the welding ring welding.
Embodiment 2:
Enclosing cover 7 parts of bivalve composite cover 1 are used the polypropylene granules single injection-molded: cylindrical open valve 6,, composite cover welding ring 9; Make pad 3 with polyisoprene, pad 3 is " 8 word " shape; With the special-purpose pellet single injection-molded of polypropylene inner cap 8.
Pad 3 is put into enclosing cover 7; Inner cap 8 is combined to form bivalve composite cover 1 through snap fit and enclosing cover 7, at last bivalve composite cover 1 and vertical type polypropylene transfusion bag 2 is formed the vertical type polypropylene transfusion bag of band bivalve plug-in composite cover through the welding ring welding.
