Infusion bag with outer barrier bag filled with inert gas

Abstract

The invention discloses an infusion bag with an outer barrier bag filled with inert gas. The infusion bag comprises a package and liquid medicine in the package. Hot melting edge sealing is conducted on the periphery of the package, and the package is a multi-layer package sequentially comprising a heat seal layer, a membrane layer, a strength layer, an adhesive layer, a heat-resistant layer, a gas layer, a hot bonding layer, a reinforcing layer and a barrier layer from inside to outside. The gas layer is filled with inert gas and internally provided with a humidity indicator. The gas layer serving as the infusion middle layer is filled with inert gas, oxygen is prevented from being left in the gas layer, and when a liquid medicine layer bag slightly leaks, oxygen can be prevented from entering the liquid medicine and damaging the liquid medicine. Meanwhile, oxygen, permeating and entering an outer sealing layer, in air can be removed. Longitudinal grooves are formed and form a road net for flowing of the inert gas, the inert gas is evenly distributed in the gas layer, and no bubbles are generated.

Description

technical field [0001] The invention specifically relates to a large infusion preparation for medical use. 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. [0003] The packaging of the infusion bag is a plastic soft bag. In some cases, the infusion bag may be slightly damaged, which is called microleakage. The implied cycle of microleakage is long, and the leak hole is very small and invisible to the naked eye, but the leak hole is enough to allow bacteria to enter the liquid medicine, causing safety problems. Due to the surface tension of the liquid, the liquid in the infusion bag cannot pass through or obviously pass through the tiny pores, so it is invisible to the naked eye. In the detection process, it is difficult to rule out such an infusion bag with micropores. There is a great safety hazard in ...

AI Technical Summary

Problems solved by technology

1. The packaging strength is still not enough, and the infusion preparations may be damaged in the process of filling and later product quality inspection, storage and transportation, and use.

2. There are always a certain number of infusion bags that are inevitably damaged. The above two technologies have not provided corresponding prevention and treatment for the possible packaging damage in the later stage, which is very likely to cause damage and the above-mentioned micro-leakage packaging into Hospital

3. Infusion bags made of the above packaging materials cannot control microleakage
