Connecting port of infusion bag

Abstract

The invention discloses a connecting port of an infusion bag, comprising a body, wherein the body is provided with a longitudinal through hole; a connecting part is arranged at one end of the body; an outlet part is arranged at the other end of the body; the connecting part is provided with two wings, and convex ribs are arranged on the two wings; one section of transitional part for connecting the outlet part with the connecting part is arranged in the middle of the body; the thickness wall of the transitional part is transitioned from thickness to thinness between the outlet part and the connecting part; a through hole is in a rhomboid shape in the connecting part; from top to bottom, the width of the through hole is transitioned from width to narrowness; and the two wings are thin wings. By adopting the rhomboid design and producing the two wings into the thin wings, the thickness of the side wall of the connecting part at the connecting port of the infusion bag is kept uniform; during heat sealing, the non-uniformity during heating is avoided, favorable heat sealing performance is obtained and materials are saved; meanwhile, by adopting the design of the transitional part, the materials are further saved.

Description

technical field [0001] The invention relates to the technical field of medical packaging, in particular to a connection port of an infusion bag. Background technique [0002] In the clinical treatment of diseases, patients are often given infusions or drugs are directly injected into the body through intravenous infusion, so medical solution packaging containers are needed. The existing liquid medicine is packaged with bottles or bags, and the infusion bag has a connection port at the output end. When sealing, insert the connection part of the connection port into the mouth of the infusion soft bag, and heat and weld the bag and the port once through special equipment. Welded and formed. In order to make the mouth of the infusion bag and the connection port welded firmly, two wings are formed on the connection part of the connection port, and ribs are formed in the two wings. In the prior art, the wall thickness of the connection part is too thick, and the heating is un...
