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.
