Embodiment 1

[0023] Embodiment 1, the infusion container sealing cover that has side-pull type infusion tube and dosing tube

[0024] The main part of the sealing cover is injection-molded with polypropylene pellets at one time, and the main part includes the cover body 3, the side-pull infusion needle catheter part 4 of the side-pull infusion tube 1, the dosing tube body 21 of the dosing tube 2 and the inner cavity Empty 12 sections. The side-pull infusion tube 1 and the dosing tube 2 are located on the same surface of the cover body 3 and the bottom sheet 35 and are basically parallel, and the distance between the outer walls of the side-pull infusion tube 1 and the dosing tube 2 is 6 mm. The sealing sheet 7, the easy-open lid 10 and the gasket fixing ring 17 are respectively injection-molded with polypropylene pellets. Spacer 11 is made of polyisoprene.

[0025] Heat seal the sealing piece 7 and the welding ring 6 of the side pull tube; put the gasket 11 into the recessed inner space ...

Embodiment 2

[0048] The main structure is the same as that of Embodiment 1, but the sealing diaphragm 5 is a plane, and the bottom cover sheet 35 is oval.

Embodiment 3

[0050] The main structure is the same as in Example 1, but the easy-to-pull ring 8 is an annular ring between two substantially parallel recessed intermittent lines on the outside of the side-pull infusion needle catheter 4 wall, and the depth of the depression is smaller than that of the side-pull infusion needle catheter 4 3 / 4 of the wall thickness.

Abstract

The invention relates to a transfusion container sealing cover with a side-pull type transfusion pipe and a drug feeding pipe, belonging to a liquid inlet and outlet pipeline of a transfusion bottle (bag) and a pipeline sealing device. The side-pull type transfusion pipe and the drug feeding pipe are fixed on the same outer surface of a cover body basically in parallel; the side-pull type transfusion pipe comprises a side-pull type transfusion needle guide pipe and a sealing sheet; the drug feeding pipe comprises a drug feeding pipe body, a gasket, a gasket fixing ring and an easily-pull cover, wherein the gasket is arranged on a gasket membrane, and the gasket fixing ring is arranged on the gasket; the cover body comprises a cover bottom sheet, a hollow cylinder and a cylinder welding ring, wherein the hollow cylinder is formed by connecting the side walls of the cover, and the cylinder welding ring is formed by outwards extending the edge of the hollow cylinder. The invention has the advantages that a double-pipe connector can realize two functions of drug feeding and transfusion, and the transfusion container sealing cover has difficult scrap dropping and easy puncture in the process of transfusing puncture; and the transfusion container sealing cover also has lower production cost.

Description

technical field [0001] The invention belongs to the technical field of medical transfusion packaging, in particular to a double-tube transfusion container sealing cover with two functions of adding medicine and transfusion. Background technique [0002] The sealing cap of the infusion container is required to have the function of infusion, preferably also the function of adding medicine. [0003] The sealing device of existing plastic transfusion bottle or transfusion bag all is to seal bottle (bag) mouth with combined plastic sealing cap, and this sealing cap is made up of three parts: inner cap, outer cap and place between inner cap and outer cap. Gaskets (such as polyisoprene gaskets). During the infusion, the gasket and the inner cover are penetrated by the resin needle, and the infusion is realized after being in contact with the medicinal liquid. Due to the thickness of the gasket and the inner cover, the gasket and the inner cover are prone to chipping during the pu...
