Three-chamber infusion bag and production method thereof

Abstract

A three-chamber infusion bag comprises an infusion soft bag. The inner side of front bag film or rear bag film is provided with strip projections. First, second and third chambers are arranged between the front bag film and the rear bag film. The first and second chambers are isolated through a strip permanent welded structure. The first and third chambers are isolated through a strip removable insufficiently-welded structure, and the second and third chambers are also isolated through a strip removable insufficiently-welded structure. A production method of the three-chamber infusion bag includes: machining the removal insufficiently-welded structures between the front bag film and the rear bag film, machining the permanent welded structure, reversing a filling passage, filling the three chambers with medicament respectively, and sealing. When the upper two parallel chambers are stressed, the strip permanent welded structure is never broken through, and accidental mixing of the medicament in the first and second chambers is prevented accordingly. During storage and transport, the removable insufficiently-welded structures between the first and third chambers as well as between the second and third chambers are located in a bent area of a folding part so that break-through is prevented.

Description

Technical field: [0001] The invention relates to packaging technology, in particular to a medical sealed container, in particular to a sealed container for transfusion preparations, in particular to a three-chamber transfusion bag and a production method thereof. Background technique: [0002] In the pharmaceutical industry, it is often necessary to mix three kinds of medicines that cannot be mixed and stored for a long time and then release them into the organism. The mixing operation of medicines is required to be carried out under aseptic conditions. In order to improve the efficiency and convenience of the dispensing process, a soft infusion bag with three independent chambers is proposed in the prior art, and the soft infusion bag has a first chamber, a second chamber and a third chamber , the first chamber, the second chamber and the third chamber are separated by the strip-shaped peelable virtual welding structure between the front and rear bag films of the infusion ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a three-chamber transfusion bag, which will solve the problem of the strip-shaped peelable virtual welding structure in the soft transfusion bag with three independent chambers in the prior art. It is easy to break through during storage and transportation, causing the technical problem of accidental mixing of medicines. At the same time, it is necessary to solve the technical problem that the bag membranes on both sides are not easy to separate and open during the filling process of medicines.
