Abstract
The utility model discloses a polypropylene transfusion bottle with a double-valve snap fit type combination cover. The polypropylene transfusion bottle comprises the double-valve combination cover and a polypropylene transfusion bottle body. The double-valve combination cover comprises an outer cover, an inner cover and a gasket; the double-valve combination cover is formed by placing the gasket in the outer cover and combining the inner cover with the outer cover through snap fit; an opening end of the polypropylene transfusion bottle body is provided with a transfusion bottle welding ring; the lower end of the double-valve combination cover is provided with a combination cover welding ring; and the polypropylene transfusion bottle body and the double-valve combination cover are connected through the two welding rings. Compared with a conventional transfusion package, the polypropylene transfusion bottle employs the design of the double-opening cover, realizes the independence of two functions of medicine feed and transfusion, prevents medical personnel from performing repeated puncture operations for the medicine feed and transfusion in an opening hole, prevents cross contamination during use, is easy to use, is simple in structure and technology, and is relatively low in production cost.
Description
Technical field
This utility model relates to a kind of polypropylene infusion bottle 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 existing transfusion package is: dosing and the shared opening cover of transfusion, and open 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 polypropylene infusion bottle with bivalve plug-in composite cover.
This utility model is realized through following technical scheme:
The polypropylene infusion bottle of band bivalve plug-in composite cover comprises bivalve composite cover 1 and polypropylene infusion bottle 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 is greater than the diameter of infusion port 5; Enclosing cover 7 extends to composite cover welding ring 9 downwards, 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 polypropylene infusion bottle of the infusion bottle welding ring 10 welding formation band bivalve plug-in composite covers of polypropylene infusion bottle 2.
Said polypropylene infusion bottle 2 is a cylindrical structure.
Said open valve 6 is cylindrical.
Said pad 3 is " circular triangle " structure, is equipped with matrix circular hole 14 up and down.Pad 3 is the figure of eight.
Said polypropylene infusion bottle 2 openings have infusion bottle welding ring 10, and enclosing cover 7 lower ends have composite cover welding ring 9, are used for and 10 welding of infusion bottle welding ring, and enclosing cover 7 closely links together with polypropylene infusion bottle 2.
The advantage of this utility model is; Compare with traditional transfusion package, this utility model adopts two opening cover designs, with dosing, two functions of transfusion independently; In same open hole, carry out dosing and the operation of transfusion repeated localised puncture when having avoided the medical worker to infuse; 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 polypropylene infusion bottle 2 are formed the polypropylene infusion bottle 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 polypropylene infusion bottle 2 are formed the polypropylene infusion bottle of band bivalve plug-in composite cover through the welding ring welding.
