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

Abstract

The invention relates to an infusion bag part with a fusiform seat, a top pull 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 infusion bag part comprises the top pull infusion tube, the dosing tube and the fusiform tube body seat, and is characterized in that: the top pull infusion tube and the dosing tube are fixed on the same surface of the fusiform tube body seat and basically parallel to each other; a top pull infusion needle conduit is hollow and provided with a sealing diaphragm, and the top end of the top pull needle conduit is provided with a top pull sealing cover for sealing the top pull needle conduit; and a gasket is arranged in the dosing tube, a gasket fixing ring is arranged on the gasket, and the top of the dosing tube is sealed by an 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 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 two functions of adding medicine and infusion. Background technique [0002] The accessories of the infusion bag are required to have the function of infusion, and it is better to have the function of adding medicine. [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. Dosing and infusion are all carried out through this single-tube channel. The disadvantage is that the sealing cover used in this structure is generally Consists of three parts: an inner cover, an outer cover, and a gasket (such as a polyisoprene gasket) placed between the inner and outer covers. 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 c...

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
