Outer composite bag infusion bag

Abstract

The invention relates to an outer composite bag infusion bag, which comprises a package and a drug liquid in the package, wherein the package comprises a drug liquid layer, a leakage detection layer and a gas barrier layer, the drug liquid layer is a non-PVC plastic film with characteristics of liquid barrier property and compatibility with the drug liquid, the leakage detection layer is vacuum, and the gas barrier layer is a plastic film having gas barrier property. According to the present invention, with the outer composite bag infusion bag, the possibly existing micro-pore leakage liquid can be observed and found out, and the outer composite bag infusion bag can be subjected to industrial batch production; by setting the vacuum degree of the leakage detection layer, the tension of thedrug liquid in the leakage hole of the drug liquid layer is broken through, such that the drug liquid can timely leak and can be observed; the gas barrier layer can effectively control the vacuum degree and the vacuum degree attenuation change in the leakage detection layer; and the production cost can be reduced, the infusion bag with the leakage hole can be effectively prevented from leaving thefactory, and the safety of medication can be ensured.

Description

technical field [0001] The invention specifically relates to a large transfusion preparation for medical use, in particular to a transfusion bag filled with five layers of co-extruded film in a composite bag. Background technique [0002] Large infusion preparations are what we often call infusion, and the finished product is also called infusion bag, which directly infuses the built-in medicinal solution into the human vein. The infusion bag is generally used in the medical process within 6 months after the production date, and the risk is high if it is overdue, so it is generally not used. [0003] Due to the substandard welding temperature of the infusion bag during processing, the aging of the welding mold, and the size deviation of the infusion packaging material, etc., there will be a small amount of damage in the infusion bag, which is called micro-leakage. Bacteria enter and contaminate the liquid medicine, and the micropores are too small to be seen by naked eyes. ...

Problems solved by technology

[0008] 2. Vacuum degree data, vacuum degree attenuation trend, vacuum pressure data applicable to leaks, relatively stable state data after vacuum degree attenuation, etc., are currently not supported by relevant data, so it is impossible to conduct tests under too many complex factors to obtain vacuum degree Requirements and material requirements for outer packaging
