Material special for medicinal transfusion bag

Abstract

The invention discloses a material special for a medicinal transfusion bag, which comprises polypropylene, polyethylene and styrene-ethylene / butane-styrene block copolymer. Due to the adoption of the technical scheme, the transfusion bag has excellent air permeability and steam blocking performance and good chemical stability, and the material is suitable for manufacturing liquid medicinal products which need high-temperature disinfection and sterilization; the material has good transparency and ensures foreign matter detection during production and use; the material has good softness, drop resistance, good heat sealing performance and high temperature resistance, and can be sterilized at the temperature of 121 DEG C; because the material does not contain halogen, the material does not cause environmental pollution during treatment after the use; and meanwhile, the bag has good blocking performance, good chemical and biological inertness and good compatibility with medicaments, and can used for packing common liquid, enteral and parenteral nutrient liquid, dialysis liquid, flushing liquid, therapeutic large-volume injection and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a special material for a medical transfusion bag. Background technique [0002] At present, polypropylene (PP) is generally used as the material of hard plastic bottles and soft plastic bags, and polypropylene (PP) is its main component. Polypropylene (PP) has good chemical stability, including resistance to strong acids, strong alkalis and most organic substances. Polypropylene (PP) has excellent air tightness and vapor barrier properties, and is especially suitable for making infusion products that require high-temperature sterilization. However, the toughness, aging resistance, high temperature resistance and low temperature resistance of polypropylene (PP) are still not up to the more stringent requirements of medical infusion bags. [0003] The structure of the medical infusion soft bag is generally five-layer or three-layer co-extruded infusion film laminated, and t...

AI Technical Summary

Problems solved by technology

Therefore, this five-layer or three-layer co-extrusion infusion film bag cannot prevent the leakage problem at the edge of the bag and the seam of the interface.

[0004] For this reason, most soft bag infusion manufacturers have set up a second or even third light inspection process, but it still cannot solve the problem of "micro-leakage", which is recognized worldwide.

At the same time, due to the use of five-layer or three-layer co-extruded infusion film as the raw material of the infusion bag, there are many procedures, long process, large resource and energy consumption, and reduced safety and controllability
