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 for being prone to the folding part.
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 easy folding part is easy-to-fold cap, easy broken rod, three kinds of forms of foldable handle.
Preferably, lid 1 can be the hollow ellipse shape cylinder that is formed by connecting lid table thin slice 8, lid sidewall 7.
The utility model has the advantages that: the seal cover that is used for large-volume infusion soft packaging bag/bottle that adopts 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 direction that the V-arrangement opening of seal dissepiment and transfusion needle get into is corresponding, has increased seal dissepiment and contact area transfusion liquid, and pressure increases thereupon; 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, and is in conjunction with other accompanying drawing, as shown in the figure; The seal cover that a kind of transfusion package container is used; Comprise lid 1, lid 1 is the hollow cylinder that is formed by connecting lid table thin slice 8, lid sidewall 7, and the hollow cylinder edge stretches out into first welding ring 6; It is welded together that first welding ring 6 is used for seal cover and for example large-volume infusion soft packaging bag of transfusion package container/bottle etc., 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.Tube for transfusion 2 is positioned at lid 1 top, is connected with lid 1, and what be connected with tube for transfusion 2 upper ends is inserting needle conduit 3, and 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, preferably for the middle circular sheet that is spill; Seal dissepiment is shallow " V " shape, opening are 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; The sealing member 5 that is used for face of weld, in this embodiment, sealing member 5 is for being prone to the folding part; Easy folding part is an easy-to-fold cap, and like Fig. 1, shown in Figure 2, the easy-to-fold cap bottom is welded on second welding ring 9; Be prone to the folding part and just can be easy to fracture, thereby make things convenient for opening, easy operating with very little power.
