Description
Technical field
This utility model relates to composite cover, particularly a kind of bivalve clamping combined cover.
Background technology
The composite cover that existing infusion bottle adopts usually is made up of three parts: inner cap, enclosing cover and the pad (as polyisoprene gasket) be placed between inner cap and enclosing cover.After in the factory medicinal liquid being poured into bottle or bag, then at bottle or bag mouth heat seal combination sealing cover, convenient when to patient infusion, in infusion bottle or bag, add medicine with medicine feeding needle; During medical worker's Clinical practice, first pull open or pry open seal cover top, then puncturing pad and inner cap with medicine feeding needle, medicinal liquid is injected in bottle or bag and carry out drug solution preparing, after drug solution preparing is good, then puncturing pad and inner cap to patient infusion with resin pin.The shortcoming of this transfusion package is: conventional plastic infusion bottle can not self-constriction, total enclosing transfusion can not be realized, dosing and transfusion share an opening cover, open and comparatively require great effort, and inner cap, combination between enclosing cover and pad are very complicated, and inner cap and enclosing cover also easily come off, so very easily cause liquid medicine contamination.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of structure simple, easy to assembly and avoid the bivalve clamping combined cover of liquid medicine contamination.
The purpose of this utility model is achieved through the following technical solutions: a kind of bivalve clamping combined cover, it comprises enclosing cover, inner cap and pad, the medial wall of described enclosing cover is provided with a buckling groove, the lateral wall of described inner cap is provided with a bulge loop, described bulge loop and buckling groove clamping seal, the top of described inner cap offers an installing hole, the bottom of pad is arranged in installing hole, the top of described enclosing cover offers multiple shoulder hole, the periphery of pad offers the cooperation step coordinated with shoulder hole, the upper end of described pad is equipped with in shoulder hole, the top of described pad offers puncturing hole, arc detent is offered bottom puncturing hole.
The top of described pad is provided with open valve.
Described shoulder hole is two.
The bottom of described pad offers a blind hole, is plugged with plug in blind hole.
This utility model has the following advantages: composite cover of the present utility model, by enclosing cover and inner cap clamping sealing, pad is arranged between enclosing cover and inner cap, make this composite cover structure simple, easy to assembly, and pad is provided with two, medicine feeding needle and transfusion needle can be separated, thus the cross-contamination between medicinal liquid can be avoided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-enclosing cover, 2-inner cap, 3-inner cap, 4-buckling groove, 5-bulge loop, 6-plug, 7-coordinates step, 8-puncturing hole, 9-arc detent, 10-open valve.
Detailed description of the invention
Be further described this utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of bivalve clamping combined cover, it comprises enclosing cover 1, inner cap 2 and pad 3, the medial wall of described enclosing cover 1 is provided with a buckling groove 4, the lateral wall of described inner cap 2 is provided with a bulge loop 5, described bulge loop 5 seals with buckling groove 4 clamping, the top of described inner cap 2 offers an installing hole, the bottom of pad 3 is arranged in installing hole, the top of described enclosing cover 1 offers multiple shoulder hole, the periphery of pad 3 offers the cooperation step 7 coordinated with shoulder hole, the upper end of described pad 3 is equipped with in shoulder hole, the top of described pad 3 offers puncturing hole 8, arc detent 9 is offered bottom puncturing hole 8, arc detent 9 can convenient operation personnel puncture, avoid puncture cushion inclined.
In the present embodiment, the top of described pad 3 is provided with open valve 10, open open valve 10, expose puncturing hole 8, further, described shoulder hole is two, therefore namely two, pad 3, the puncturing hole 8 of one of them pad 3 is dosing mouth, and the puncturing hole 8 of another pad 3 is infusion port.
In the present embodiment, the bottom of described pad 3 offers a blind hole, is plugged with plug 6 in blind hole, and plug 6 can close fast, thus ensures that medicinal liquid is not revealed.
Work process of the present utility model is as follows: be arranged on by pad 3 in the installing hole of inner cap 2, then inner cap 2 is inserted in enclosing cover 1, and enclosing cover 1 and inner cap 2 are sealed by bulge loop 5 and buckling groove 4 clamping, now, the upper end of pad 3 is through shoulder hole, and the cooperation step 7 on pad 3 coordinates with shoulder hole, then open valve 10 is arranged on the upper end of pad 3, combined by the clamping of enclosing cover 1 with inner cap 2, pad 3 is arranged between enclosing cover 1 and inner cap 2, thus makes this composite cover structure simple, easy to assembly.
