Infusion bag part with fusiform seat, side pull filling infusion tube and gasket ring dosing tube

Abstract

The invention relates to an infusion bag part with a fusiform seat, a side pull filling infusion tube and a gasket ring dosing tube, and belongs to a pipeline for liquid to pass in and out of an infusion bag and a pipeline sealing device. The side pull filling infusion tube and the dosing tube are basically parallel to each other and fixed on the same surface of the fusiform tube body seat; the side pull filling infusion tube consists of a connecting tube body, a side pull infusion needle conduit and a sealing strip; the dosing tube consists of a dosing tube body, a concave gasket groove, a gasket, a gasket fixing ring and an easy open end; and the gasket is provided with the gasket fixing ring which is in compression joint with the easy open end. The infusion bag part has the advantages that: the infusion bag part is a double tube integrated infusion bag part, can realize the functions of filling, dosing and infusing, reduce welding positions during infusion production, and reduce the probability of liquor leakage; and meanwhile, scraps are difficult to fall off in the process of infusion and puncture, the infusion bag part is convenient to puncture, and the production cost of the infusion bag part is relatively low.

Description

technical field [0001] The invention belongs to the technical field of medical infusion packaging, in particular to a double-tube infusion bag accessory with three functions of filling, dosing and infusion. Background technique [0002] Infusion bag accessories are required to have the functions of filling, dosing and infusion. [0003] There are generally two types of existing infusion bag accessories. One is a single-tube structure, which is composed of an interface and a sealing cover. Filling, dosing and infusion are all carried out through this single-tube channel. The disadvantage is that the structure used The sealing cap generally consists of three parts: an inner cap, an outer cap, and a gasket (such as a polyisoprene gasket) placed between the inner cap and the outer cap. During the infusion, a thick resin needle is used to penetrate the spacer and the inner cover. During the puncture process, the spacer and the inner cover are prone to chipping. When the drug is ...

AI Technical Summary

Problems solved by technology

During the infusion, a thick resin needle is used to penetrate the spacer and the inner cover. During the puncture process, the spacer and the inner cover are prone to chipping. When the drug is added, it will be punctured many times, which further increases the possibility of chipping. It often leads to the contamination of the liquid medicine; and the puncture resistance is large, and it is not easy to operate; in addition, the production cost of this kind of sealing cap is also high

The other is two single-tube structures side by side, one of which is a drug feeding tube and the other is an infusion tube. This double-tube structure is that the two independent mouth tubes are sealed and welded with the film of the infusion bag respectively. When producing the infusion bag There are two welding parts, the production process cost is higher, and the probability of chemical liquid leakage is increased
