Outer barrier flushing fluid bag filled with inert gas

Abstract

The invention provides a flushing solution with an external barrier bag filled with inert gas. The flushing solution is formed by a package and the flushing solution in the package, wherein materials in the package are respectively PP (Poly Propylene) resin on a heat sealing layer, POE (Polyolefin Elastomer) resin on a membrane layer, POE resin on a strength layer, POE resin on an adhesion layer, thermoplastic resin on a heat-resisting layer, negative-pressure gas in a gas layer, PP resin on a hot adhesion layer, polyamide resin on a strengthening layer and PET (Polyester) resin on a barrier layer in sequence from inside to outside; the gas layer is internally filled with the inert gas. According to the flushing solution with the external barrier bag filled with the inert gas, provided by the invention, a liquid medicine layer can meet integration with the flushing solution and high barrier performance on liquid; the gas layer is internally filled with the inert gas, oxygen is prevented from remaining in the gas layer, the oxygen is prevented from entering the liquid medicine to damage the liquid medicine, and meanwhile, the oxygen in the air permeating and entering the gas layer from an external sealing layer can be resisted; longitudinal grooves are formed in the inner surface of the external sealing layer, and the inert gas is even everywhere in the gas layer; the percent of pass of finished products leaving a factory of flushing solution packaging bags is increased, more guaranteed flushing solution is provided for medical units, and medication safety of patients is ensured.

Description

technical field [0001] The invention specifically relates to a medical flushing liquid preparation. Background technique [0002] The flushing solution is a medical preparation, which is used to flush blood stains during medical operations. Specifically, washing the instruments used in the operation (such as: scalpel, scissors), washing the human tissue parts where the operation is performed, and even washing the internal organs and abdominal cavity of the human body. [0003] The packaging of the irrigating solution is a plastic soft bag. In some cases, the packaging bag of the rinsing solution may be slightly damaged, which is called micro-leakage. Micro-leakage has a long hidden period, 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 washing liquid, causing safety problems. Due to the surface tension of the liquid, the liquid in the packaging bag cannot pass through or obviously pass through the ...

AI Technical Summary

Problems solved by technology

1. The packaging strength is still insufficient, and the packaging may be damaged during the filling and subsequent product quality inspection, storage, transportation and use of the flushing liquid preparation

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

3. The flushing liquid packaging bag made of the above packaging materials cannot control the microleakage
