Embodiment 1

[0017] Embodiment 1, sealing cover of infusion container with side-pull type infusion tube

[0018] The main part of the sealing cover is injection-molded with polypropylene pellets at one time, including the cover body 3, the side-pull infusion needle catheter 4 of the side-pull infusion tube 1, and the two parts are an integrated structure. The side-pull infusion tube 1 and the cover body 3 The holes in the central part of the tube are communicated and connected; the sealing sheet 7 is injection-molded with polypropylene pellets; the sealing sheet 7 is heat-sealed with the conduit welding ring 6 on the side-pull infusion needle catheter 4, and it becomes an infusion solution with a side-pull type infusion tube The container is sealed with a lid.

[0019] The specific structure and size of each part are as follows:

[0020] Side pull infusion tube 1:

[0021] The side-pull infusion tube 1 is formed by connecting two parts, the side-pull infusion needle conduit 4 and the sea...

Embodiment 2

[0033] The main structure is the same as that of Embodiment 1, but the sealing diaphragm 5 is a plane.

Embodiment 3

[0035] The main structure is the same as that in Example 1, but the easy-to-pull ring 8 is an annular ring between two substantially parallel concave 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 wall 3 / 4 thick.

Abstract

The invention relates to a transfusion container sealing cover with a side-pull type transfusion pipe, belonging to a liquid inlet and outlet pipeline of a transfusion bottle (bag) and a pipeline sealing device, namely an accessory of a transfusion container. The side-pull type transfusion pipe is communicated with a hole in the center of a cover body and is formed by connecting a side-pull type transfusion needle guide pipe and a sealing sheet; a cavity of the side-pull type transfusion needle guide pipe is provided with a sealing membrane, the outer wall is provided with an easily-pull ringand a pull sheet; and the cover body comprises a circular thin sheet, a hollow cylinder and a welding ring. The transfusion container sealing cover with the side-pull type transfusion pipe has the advantages of difficult scrap dropping and easy puncture in the process of transfusing puncture as well as lower production cost; and the easily-pulling structure of the easily-pull ring is convenient for transfusion operation.

Description

technical field [0001] The invention belongs to the technical field of medical transfusion packaging, in particular to a sealing cover of a transfusion container (bottle or bag) with a side-drawing transfusion tube, that is, an accessory of the transfusion container. Background technique [0002] 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 puncture process, which often leads to contamination of the liquid medicine; the puncture resistance is h...
