Abstract
The utility model discloses a combination cover with double draw rings used for a transfusion container, which is composed of an outer cover, an inner cover and a gasket. The outer cover is composed of a first circular cover body and a first protruding platform body; the first circular cover body extends downwards to form a welding ring and extends upwards to form the first protruding platform body; two hollow draw rings in parallel arrangement are arranged on the first protruding platform body; the hollow draw rings are connected with the first protruding platform body through unlatching grooves; the inner cover is composed of a second protruding platform body and a second circular cover body; and recessed circular holes are arranged on the gasket and below the gasket. The advantages of the combination cover with double draw rings used for a transfusion container are that two functions of adding medicine and transfusion are separated by adopting the design of a double unlatching cover body; repeat puncture operations of adding medicine and transfusion in the same unlatching hole by the medical personnel are avoided; cross contamination during the usage process is avoided; unlatching is more convenient; and producing cost is relatively low.
Description
Technical field
This utility model is moulded the accessory that relates to a kind of plastic infusion bottle or bag, particularly relates to a kind of infusion vessel double-tearing ring composite cover with dosing and two kinds of functions of transfusion.
Background technology
Existing plastic container for infusion is made up of three parts with composite cover: inner cap, enclosing cover and place inner cap and enclosing cover between pad (as the polyisoprene pad), belong to infusion bottle or bag accessory.After in factory, medicinal liquid being poured into bottle or bag, convenient the time again at bottle or bag mouth heat seal seal combination lid to patient infusion, with the dosing pin to infusion bottle or bag in add medicine; During the clinical use of medical worker, draw back or pry open the seal cover top earlier, then with dosing pin puncture pad and inner cap, will medicinal liquid inject and carry out the medicinal liquid preparation in bottle or the bag, after medicinal liquid prepared, puncture pad and inner cap of reuse fat pin given patient infusion.The shortcoming of this composite cover is dosing and the shared opening cover of transfusion, opens effort, and easily causes liquid medicine contamination.
The utility model content
The purpose of this utility model is to provide a kind of infusion vessel double-tearing ring composite cover.
This utility model is achieved by the following technical solution:
A kind of infusion vessel double-tearing ring composite cover, comprise enclosing cover 1, inner cap 2, pad 3, it is characterized in that: enclosing cover 1 is made up of the first circular lid 4 and the first convex stage body 7, and the first circular lid 4 extends to form welding ring 8 downwards, and the diameter of welding ring 8 is greater than the diameter of the first circular lid 4; The first circular lid 4 extends upward and forms the first convex stage body, 7, the first convex stage bodies 7 and be provided with two hollow draw rings 6 that are arranged in parallel, and is connected by opening groove 10 between hollow draw ring 6 and the first convex stage body 7; Described inner cap 2 is made up of the second convex stage body 9 and the second circular lid 10, and the second circular lid 10 extends upward and forms the second convex stage body 9, extends to form buckling groove 11 downwards; The second convex stage body 9 is provided with matrix sealing ring 5, matrix sealing ring 5 and pad 3 meshing sealings; Buckling groove 11 and enclosing cover 1 are combined to form composite cover by snap fit.
The described second convex stage body 9 is 0.2-0.5mm with the thickness of pad 3 contacts site.
The described second convex stage body 9 is 0.35mm with the thickness of pad 3 contacts site.
The described first convex stage body 7 is " 8 word " shape structure.
Described opening groove 10 is circular.
Described pad 3 is " 8 word " type structure, is equipped with the matrix circular hole up and down.
Advantage of the present utility model is, compare with traditional composite cover, this utility model adopts two opening cover designs, with dosing, two functions of transfusion independently, avoided the medical worker in same open hole, to carry out dosing and the operation of transfusion repeated localised puncture, avoided the cross-contamination of use, opened more conveniently, and production cost is lower.
Description of drawings
Fig. 1: be cross-sectional view of the present utility model;
Fig. 2: be the structural representation of looking up of the present utility model;
1 is enclosing cover, the 2nd among the figure, and inner cap, the 3rd, pad, 4 are first circular lids, the 5th, and matrix sealing ring, the 6th, hollow draw ring, 7 are first convex stage bodies, the 8th, and welding ring, 9 is that the second convex stage body, 10 is second circular lids, the 11st, buckling groove.
The utility model is described in further detail below in conjunction with Fig. 1 and Fig. 2, but be not limited to this utility model.
The specific embodiment
A kind of infusion vessel double-tearing ring composite cover, comprise enclosing cover 1, inner cap 2, pad 3, wherein enclosing cover 1 is made up of the first circular lid 4 and the first convex stage body 7, and the first circular lid 4 extends to form welding ring 8 downwards, and the diameter of welding ring 8 is greater than the diameter of the first circular lid 4; The first circular lid 4 extends upward and forms the first convex stage body 7, the first convex stage body 7 is " 8 word " shape structure, the first convex stage body 7 is provided with two hollow draw rings 6 that are arranged in parallel, be connected by opening groove 10 between hollow draw ring 6 and the first convex stage body 7, opening groove 10 is circular, hollow draw ring 6 is opened the back and is formed the dosing hole, treats to open another hollow draw ring 6 again after dosing finishes, and realizes that dosing and transfusion function are independent; Described inner cap 2 is made up of the second convex stage body 9 and the second circular lid 10, and the second circular lid 10 extends upward and forms the second convex stage body 9, extends to form buckling groove 11 downwards; The second convex stage body 9 is provided with matrix sealing ring 5, and matrix sealing ring 5 and pad 3 meshing sealings are avoided leakage, and buckling groove 11 and enclosing cover 1 are combined to form composite cover by snap fit; The second convex stage body 9 is 0.35mm with pad 3 contact site thickness, realizes that also being convenient to transfusion needle when the obstruct medicinal liquid contacts with pad can more easily puncture.Pad 3 is " 8 word " type structure, is equipped with the matrix circular hole up and down, is convenient to biopsy needle guide and punctures.(seeing Fig. 1 and Fig. 2).
