Abstract
The utility model provides a sealing cover used for an infusion packaging container, which comprises a cover body, an infusion pipe, a needle insertion conduit and a sealing member, wherein the cover body is a hollow cylinder which is formed by connecting a cover surface sheet and a cover side wall, and a first welding ring extends outward from the margin of the hollow cylinder; the inside diameter of the upper end is less than that of the lower end of the infusion pipe, and the lower end of the infusion pipe is communicated with the inner cavity of the cover body; the needle insertion conduit is connected with the upper end of the infusion pipe and communicated with the inner cavity of the cover body and the inner cavity of the infusion pipe, the axial line of the needle insertion conduit, the axial line of the cover body and the axial line of the infusion pipe are on the same line; a sealing diaphragm is arranged at the transition site of the needle insertion conduit and the upper end of the infusion pipe, and a second welding ring is formed at the opening of the needle insertion conduit and raised towards the two sides; and the sealing member is arranged on the second welding ring at the opening of the needle insertion conduit. The sealing cover can be used to increase the holding force on the infusion needle and prevent slippage of the infusion needle or liquid leakage, is easy to operate and helps increase work efficiency.
Description
Technical field
This utility model relates to the medical packaging field, particularly relates to the seal cover that a kind of transfusion package container is used.
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; This seal cover is made up of three parts: inner cap, enclosing cover and place inner cap and enclosing cover between pad (like 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 are prone to 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.Announce a kind of fusiformis body seat list standpipe that the Chinese patent 201020282741.0 of mandate relates to and solved the problems referred to above to a certain extent; But in specific operation process; Promptly in the infusion process after thrusting transfusion needle in the process or thrusting; Bottle cap sometimes to transfusion needle fixing, grip is not very good, possibly exist to come off or the situation of leakage, causes unnecessary waste or pollution condition.
The utility model content
The purpose of this utility model provides a kind of infusion vessel and uses seal cover.
A kind of infusion vessel is used seal cover, comprises lid 1, tube for transfusion 2, and inserting needle conduit 3, sealing member 5: lid 1 is the hollow circular cylinder that is formed by connecting lid table thin slice 8, lid sidewall 7, and hollow circular cylinder edge stretches out into first welding ring 6; Tube for transfusion 2 upper end internal diameters are less than the bottom internal diameter, and the bottom communicates with lid 1 hollow; Inserting needle conduit 3 is connected with tube for transfusion 2 upper ends; Communicate with lid 1, tube for transfusion 2 hollows; The axis is a same straight line, is provided with seal dissepiment 4 at inserting needle conduit 3 and tube for transfusion 2 upper end transition positions, second welding ring 9 of the oriented both sides of inserting needle conduit 3 opening parts protrusion; Sealing member 5 is arranged on second welding ring 9 of inserting needle conduit 3 opening parts.
Preferably, inserting needle conduit 3 is the circular cylinder of hollow, and internal diameter is slightly less than tube for transfusion upper end internal diameter.
Preferably, seal dissepiment 4 middle parts that are arranged on inserting needle conduit 3 and tube for transfusion 2 upper end transition positions are spill, can make shallow " V " shape, and opening is towards the opening part of inserting needle conduit 3.
Preferably, said sealing member 5 is easily tore films.
Preferably, lid 1 can be the hollow ellipse shape cylinder that is formed by connecting lid table thin slice 8, lid sidewall 7.
Adopt the seal cover that is used for large-volume infusion soft packaging bag/bottle of this utility model; Because the large-volume infusion soft packaging bag is in inversion state in infusion process, the tube for transfusion of seal cover this moment big up and small down round table-like, the V-arrangement opening of seal dissepiment is corresponding with the direction of transfusion needle entering; Seal dissepiment and contact area transfusion liquid have been increased; Pressure increases thereupon, and the chucking power to transfusion needle has also strengthened greatly simultaneously, has prevented the landing or the phenomenon of leakage of transfusion needle.

The specific embodiment
Embodiment 1
Fig. 1 is the structure of this utility model embodiment; In conjunction with accompanying drawing 2, accompanying drawing 3, the seal cover that a kind of transfusion package container is used comprises lid 1; Lid 1 is the hollow cylinder that is formed by connecting lid table thin slice 8, lid sidewall 7; The hollow cylinder edge stretches out into first welding ring, 6, the first welding ring 6, and to be used for seal cover and for example large-volume infusion soft packaging bag of transfusion package container/bottle etc. welded together, thereby accomplish the sealing of large-volume infusion soft packaging bag/bottle.Preferably, lid also can be made the hollow ellipse shape cylinder that is formed by connecting lid table thin slice, lid sidewall.Be positioned at lid 1 top, the tube for transfusion 2 that is connected with lid 1, what be connected with tube for transfusion 2 upper ends is inserting needle conduit 3, lid 1, tube for transfusion 2 and inserting needle conduit 3 three parts are a global facility of single injection-molded; Three parts are that hollow communicates, and the axis is identical, and wherein, the upper end internal diameter of tube for transfusion 2 is less than the bottom internal diameter; Form up-small and down-big state, section is trapezoidal, and tube for transfusion 2 is provided with seal dissepiment 4 with the transition position that is connected of inserting needle conduit 3, is used to isolate transfusion liquid and contacts with extraneous air; Seal dissepiment 4 is beneficial to transfusion needle to puncture for the middle circular sheet that is spill, preferably, and seal dissepiment is shallow " V " shape; Opening is towards the opening part of inserting needle conduit 3, and inserting needle conduit 3 opening parts stretch out respectively and form second welding ring 9, are used for the sealing member 5 of face of weld; In this embodiment, sealing member 5 is an easily tore film, to realize better sealing effectiveness; Easily tore film has at least an end to extend to the outside of second welding ring 9, forms pulling-on piece, so that tear.
