Abstract
The utility model provides a side-pull type infusion sealing cover, which belongs to the medical infusion bottle (bag) fittings, particularly to a sealing device for a liquid inlet and outlet channelof an infusion bottle (bag). The side-pull type infusion sealing cover comprises a pipe body and a dust cap, and the edges at two end openings of the pipe body respectively extend outwards to form welded rings which are respectively connected with a bottle (bag) opening and the dust cap. The side-pull type infusion sealing cover is characterized in that the welded ring at one end of the pipe bodyis connected with the dust cap in a sealing manner, and a sealing diaphragm is arranged on the pipe body in the hollow cross section far away from the dust cap; and an easily-pulled ring is arranged on the pipe body on the outer side of the wall close to the dust cap, the position of the easily-pulled ring is between the sealing diaphragm and the dust cap, and a pull piece is connected to the easily-pulled ring. The side-pull type infusion sealing cover has the advantages of low probability of contaminated liquid medicine or dusting off during the infusion and puncture, smaller puncture resistance, and easy operation; moreover, the manufacturing cost of the sealing cover is lower compared with that of the prior composite plastic sealing covers.
Description
Technical field
This utility model belongs to the closing device of the turnover fluid passage of medical infusion bottle (bag) accessory, particularly infusion bottle (bag).
Background technology
The closing device of existing plastic infusion bottle or transfusion bag all is to come sealing bottles (bag) mouth with the combined plastic seal cover, and this seal cover is made up of three parts: inner cap, enclosing cover and place inner cap and enclosing cover between pad (as the polyisoprene pad).When transfusion,, contact the back with medicinal liquid and realize transfusion with resin needle penetration pad and inner cap.Because pad and inner cap are thicker, in piercing process, pad and inner cap all easily fall bits, often cause medicinal liquid contaminated; Penetration Resistance is big, and is not easy to operate; In addition, the production cost of this combined plastic seal cover is also higher.
Summary of the invention
The purpose of this utility model provides a kind of bits that are difficult for falling in piercing process, be easy to puncture and the lower transfusion seal cover of production cost.
Structure of the present utility model is:
Side-pull type transfusion seal cover, comprise body and dust cap, body two-port edge becomes to be used for and bottle (bag) mouthful welding ring that is connected and the welding ring that is used for being connected with dust cap to extension respectively, it is characterized in that, the welding ring that is connected with dust cap and the dust cap of body one end are tightly connected, and body is provided with seal dissepiment away from the hollow cross-section of dust cap section; Body is provided with easy-to-draw circle on the wall outside near dust cap, the position of easy-to-draw circle is connected with pulling-on piece on the easy-to-draw circle between seal dissepiment and dust cap.When making infusion bottle (bag), the welding ring of the body other end of the present utility model is used for being tightly connected with the opening of infusion bottle (bag), and medicine is sealed in the infusion bottle (bag).When using this infusion bottle (bag),,, expose sky in the body, pass the intravital seal dissepiment of pipe, realize transfusion with transfusion resin pin to remove dust cap with the easy-to-draw circle of pulling-on piece pull-up.Because this utility model side-pull type transfusion seal cover has been established twice sealing-----seal dissepiment and dust cap to medicinal liquid, particularly dust cap has sealing medicinal liquid and the extruding and the percussion of resisting in transportation, the storage, as long as then seal dissepiment just can seal medicinal liquid, do not need extruding and ballistic function in opposing transportation, the storage, seal dissepiment can be done very thinly rather than existing thicker pad and inner cap, the resin pin of then infusing passes seal dissepiment and just is difficult for falling bits, be easy to puncture again, thereby reach goal of the invention.
Attractive in appearance after pulling off easy-to-draw circle for convenience and pulling off easy-to-draw circle made the tube body wall outside with easy-to-draw circle and goes up annular rings between substantially parallel two lines that are interrupted depression, its cup depth be approximately body pipe thickness 4/5～2/5.
Seal dissepiment is a plane or slightly becomes " V " shape, the concave surface facing dust cap of " V " shape.Slightly become " V " shape as seal dissepiment, just can find the middle part of seal dissepiment when transfusion resin pin passes seal dissepiment accurately, can not stab tube wall.
Advantage of the present utility model: compare with existing combined plastic seal cover, in the vein puncture process, be difficult for falling bits, can not cause medicinal liquid contaminated; Penetration Resistance is littler, easy operating; In addition, the production cost of this seal cover is also low than existing combined plastic seal cover.

The specific embodiment
Embodiment 1: side-pull type transfusion seal cover
This utility model side-pull type transfusion seal cover comprises body 1 and dust cap 4.
Become the body 1 be used for bottle (bag) mouth welding ring 2 that is connected and welding ring 7 that is used for being connected to extension respectively with polypropylene granules single injection-molded two-port edge, and cast the interior seal dissepiment 3 of body 1 simultaneously with dust cap 4.The welding ring 7 and the dust cap 4 of body 1 one ends are tightly connected, and body 1 claims afterbody with dust cap 4 links, and end opposite claims head.Head sections and end segment are with the sealed isolation in seal dissepiment 3 boundaries.Body 1 tail length is 20.0mm, and internal diameter is 5.5mm, and tapering cooperates with transfusion needle, and wall thickness is 2.0mm.Body 1 afterbody welding ring 7 internal diameters are 5.5mm, and external diameter is 9.5mm, and the solder side width is 4.0mm, and thickness is 2.0mm.Body 1 head welding ring 2 internal diameters are 26.0mm, and external diameter is 30.0mm, and the solder side width is 4.0mm, and thickness is 2.0mm.Body 1 is provided with near the wall of dust cap 4 outside wide for 3.0mm thickness is 1.5mm, easy-to-draw circle 5, the position of easy-to-draw circle 5 is connected with pulling-on piece 6 on the easy-to-draw circle 5 between seal dissepiment 3 and dust cap 4.Seal dissepiment 3 is a plane, and its thickness is 1.0mm.After tearing easy-to-draw circle 5, can infuse with transfusion needle puncture seal barrier film 3 with pulling-on piece 6.
