Double interface of tearable film for soft infusion bag

Abstract

The invention belongs to the technical field of medical packaging and discloses a double interface of tearable film for a soft infusion bag. The double interface comprises a binder, wherein two interface bodies respectively and correspondingly inserted into an infusion hole and a dosing hole of the soft infusion bag are fixedly connected to the binder, each interface body comprises a dosing portion and a seal portion, the seal portions are located at the tops of the dosing portions, the middles of the seal portions are provided with through holes, the middles of the dosing portions are provided with medicine channels for dosage, the through holes are coaxial with the dosage channels, and the inner diameter of each through hole is greater than the diameter of each medicine channel. Seal compressing rings are clamp-connected to the inner walls of the upper ends of the through holes of the seal portions, rubber plugs are arranged below the seal compressing rings, the bottoms of the rubberplugs are provided with seal membranes covering the medicine channels, and the tops of the through holes of the seal portions are provided with transparent adhered film. By adopting the scheme, the double interface is simple in process and good in sealing performance.

Description

technical field [0001] The application of the invention belongs to the technical field of medical packaging, and specifically discloses a double interface of an easy-tear film for a soft transfusion bag. Background technique [0002] In clinical medical treatment, in the infusion of patients or the direct injection of drugs into the body through intravenous infusion, a packaging container for medical solution is required. At present, most of the liquid medicine packaging adopts BFS packaging technology, and the film cover products of the liquid medicine packaging container adopt the method of flat film, and the film material is basically aluminum film, which is not conducive to observing the internal conditions of the infusion hole and the dosing hole, and there are many punctures and debris , Difficulty in puncture, exudation and other problems. Moreover, the soft bag interface of the prior art is mainly composed of an interface body, an inner cover, an outer cover and a g...

AI Technical Summary

Problems solved by technology

[0003] 1. There are more contacts with the liquid medicine (both the interface body and the inner cover are in contact with the liquid medicine), resulting in poor sealing;

[0004] 2. The production process is more complicated;

[0005] 3. Air leakage and secondary pollution are prone to occur when inserting and pulling out needles
