Abstract
The utility model provides a sealing cover for a transfusion packaging container, which comprises a cover body, a transfusion tube, a needle inlet guide tube and a rubber plug. The cover body is a hollow cylinder, a cover surface sheet is connected with a cover side wall to form the hollow cylinder, and the edge of the hollow cylinder outwards extends to form a first welding ring; the inner diameter of the upper end of a transfusion tube is smaller than that of the lower end of the transfusion tube, and the lower end of the transfusion tube is communicated with a hollow portion of the cover body; the needle inlet guide tube is connected with the upper end of the transfusion tube and communicated with the hollow portion of the cover body and a hollow portion of the transfusion tube, a central axes of the needle inlet guide tube, the cover body and the transfusion tube are on the same straight line, a sealing diaphragm is disposed at a transition position of the needle inlet guide tube and the upper end of the transfusion tube, and a second welding ring which is protruded to two sides is arranged at an opening of the needle inlet guide tube; and the rubber plug is a cylinder, the diameter of the rubber plug corresponds to the inner diameter of the needle inlet guide tube, and the rubber plug is arranged in a tube cavity, which is close to the opening, of the needle inlet guide tube. The sealing cover strengthens clamping force to a transfusion needle, prevents the transfusion needle from slipping or leaking liquid, simultaneously, is easy in operation, and improves 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, and 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, plug 6: lid 1 is the hollow circular cylinder that is formed by connecting lid table thin slice 9, lid sidewall 8, and hollow circular cylinder edge stretches out into first welding ring 7; 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 10 of the oriented both sides of inserting needle conduit 3 opening parts protrusion; Plug 6 is a cylinder, and diameter is corresponding with inserting needle conduit 3 internal diameters, is arranged in the tube chamber of inserting needle conduit 3 near opening part.
Preferably, seal dissepiment 4 middle parts that are arranged on inserting needle conduit and tube for transfusion upper end transition position are spill, can make shallow " V " shape, and opening is towards the opening part of inserting needle conduit 3.
Preferably, plug 6 upper and lower surfaces are recessed to the center respectively.
Preferably, plug 6 upper surfaces are provided with easily tore film 5.
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.
