Summary of the invention:
The object of the present invention is to provide a kind of dual pathways sealed interface for infusion vessel, the described this dual pathways sealed interface for infusion vessel will solve debris of rubber stopper in the seal cover with two passages on prior art infusion vessel and fall into the technical problem of medicinal liquid.
This dual pathways sealed interface for infusion vessel of the present invention, comprise an interface body, wherein, in described interface body, be provided with first vestibule and second vestibule, the first described vestibule is communicated with upper surface and the lower surface of interface body, between the upper surface of the first vestibule and lower surface, be provided with one deck barrier film, the second described vestibule is communicated with upper surface and the lower surface of interface body, in the upper inside wall of the first vestibule, be along the circumferential direction provided with the sealing ring outstanding to axis direction, the described mutual welding of the inwall with the first vestibule, the top of the second vestibule is filled with a plug.
Further, the first vestibule and the second vestibule parallel interval.
Further, described sealing ring is made up of elastomer.
Further, plug the injection moulding of the top of the second vestibule and with interface body welding.
Further, the periphery of described interface body extends to form a bottle cap body downwards.
Or, in interface body, include first tubular body and second tubular body, the first described tubular body and second tubular body axially upwards the extending to form along the first vestibule and the second vestibule by interface body respectively, sealing ring is positioned at the upper end of the first tubular body, and plug is positioned at the upper end of the second tubular body.
Further, the upper end periphery of the first tubular body and the upper end periphery of the second tubular body are provided with separately ring-type radial convex and go out step.
Further, the upper-end inner diameter of the first tubular body is less than the middle part internal diameter of the first tubular body.
Further, the two ends, left and right of interface body are respectively wedge shape.
Compared with the prior art, its effect is actively with obvious in the present invention.The present invention arranges sealing ring in the inwall of the infusion channel of the dual pathways seal cover of infusion vessel, utilizes sealing ring to realize the sealing of seal cover and syringe needle for transfusion device, and the syringe needle for transfusion device plug that need not puncture, has avoided debris of rubber stopper to fall into the problem of medicinal liquid.The mutual welding of inwall of sealing ring and the first vestibule, in the time that syringe needle for transfusion device inserts, sealing ring can not be moved, and guarantees the reliability of sealing function.
