Abstract
The utility model discloses a stepped infusion seal cover with an insert pipe, which belongs to the medical infusion packaging part, and comprises a pipe body and a stepped easily-pulled dustproof cover, and is characterized in that the edge of one end of the pipe body extends outwards to form a fastening ring, the inside surface of the cover plate of the stepped easily-pulled dustproof cover is provided with two concave rings which have the concentric circles and are separated from each other, an easily-pulled ring is arranged between the two the concave rings, the outer surface of theeasily-pulled ring is connected with a pull piece, the outside surface of the side wall of the fastening ring is connected with the inside surface of the fastening ring of the cover plate in a fastening way, the hollow section of the pipe body, which is far away the cover plate, is provided with a seal membrane, and the cover plate of the stepped easily-pulled dustproof cover is in a step shape. Compared with the existing combined plastic seal cover, the utility model has the advantages that the scraps are not easy to fall off during the puncture process in infusion, the liquid medicinecan not be polluted, the resistance of the puncture is lowered, the operation is easy, and in addition, the production cost of the seal cover is lower than that of the existing combined plastic seal cover.
Description
Technical field
This utility model belongs to medical infusion packing accessory.
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:
A kind of with the stairstepping transfusion seal cover that inserts body, comprise a body and the easy-to-draw dust cap of stairstepping, it is characterized in that: body one port edge stretches out into body snapping ring, the inner surface of the cover plate of the easy-to-draw dust cap of stairstepping is provided with the concentrically ringed depression circle of twice separately, between the twice depression circle is easy-to-draw circle, is connected with pulling-on piece on the outer surface of easy-to-draw circle; The sidewall outer surface of body snapping ring becomes button to be connected with the cover plate inner surface of cover plate snapping ring; Be provided with seal dissepiment at body away from the hollow cross-section of cover plate; The cover plate of the easy-to-draw dust cap of stairstepping becomes to be stairstepping.
When making infusion bottle (bag), the merging snapping face that the snapping face of the snapping face of body snapping ring and cover plate snapping ring forms can be 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),, also just removed the core of cover plate simultaneously, exposed sky in the body, passed the intravital seal dissepiment of pipe, realized transfusion with transfusion resin pin with the easy-to-draw circle of pulling-on piece pull-up.Because this utility model has been established twice sealing to medicinal liquid: the easy-to-draw dust cap of seal dissepiment and stairstepping, particularly the easy-to-draw dust cap of stairstepping 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.
The purpose that seals more for the cover plate inner surface of the sidewall outer surface of realizing body snapping ring and cover plate snapping ring, on the sidewall outer surface of body snapping ring, be provided with the sealing ring of protrusion, the concave shape driving fit coupling of the cover plate inner surface of the shape of sealing ring projection and cover plate snapping ring.
Seal dissepiment is the plane or slightly becomes " V " shape, the easy-to-draw dust cap of concave surface facing stairstepping of its " V " shape.Slightly become " V " shape as seal dissepiment, just can find the middle part of seal dissepiment when the resin pin of then infusing 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:
Present embodiment is a kind of to comprise a body 1 and the easy-to-draw dust cap 4 of stairstepping with the stairstepping transfusion seal cover that inserts body.
Tubulation part: become the body 1 of body snapping ring 2 with polypropylene granules single injection-molded one port edge to extension, and cast the seal dissepiment 3 in the body 1 simultaneously.Seal dissepiment 3 is located at the hollow cross-section away from body snapping ring 2, and its thickness is 1.0mm, and seal dissepiment 3 slightly becomes " V " shape, the concave surface facing body snapping ring 2 of its " V " shape.Body 1 length is 20.0mm, and internal diameter is 5.5mm, and tapering cooperates with transfusion needle, and wall thickness is 2.0mm; Body snapping ring 2 internal diameters are 26.0mm, and external diameter is 28.0mm, and snapping face width degree is 2.0.mm, and thickness is 2.0mm.
System cover: with the easy-to-draw dust cap 4 of polypropylene granules single injection-molded stairstepping.The thickness of the cover plate 13 of the easy-to-draw dust cap 4 of stairstepping is 2.0mm, and its inner surface 16 is provided with the concentrically ringed depression circle 9 of twice separately, is easy-to-draw circle 5 between the twice depression circle 9, and easy-to-draw circle 5 width are 3.0mm, are connected with pulling-on piece 6 on the outer surface of easy-to-draw circle 5.Easy-to-draw dust cap 4 peripheral side wall of stairstepping are provided with cover plate snapping ring 14, and its internal diameter is 28.0mm, and external diameter is 30.0mm, and snapping face width degree is 2.0mm, and thickness is 3.5mm.The cover plate 13 of the easy-to-draw dust cap 4 of stairstepping is stairstepping.
Two unit constructions: the cover plate inner surface 8 of the cover plate snapping ring 14 of the easy-to-draw dust cap 4 of stairstepping is buckled on the sidewall outer surface (7) of body snapping ring 2 of body 1, form button connection closely, it is a kind of with the stairstepping transfusion seal cover that inserts body to make present embodiment.
