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

Embodiment Construction

[0030] In the following, the present invention will be described in further detail through the specific description of the embodiments, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0031] The first item of the present invention is a medical infusion bag. In the known technology, the material composition of the medical infusion bag mainly includes polypropylene (PP).

[0032] Polypropylene (PP) is the main component of medical infusion bags. 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.

[0033] The medical transfusion bag of the present invention actually includes two different schemes for s...

Abstract

The invention discloses a medical infusion bag. The infusion bag is manufactured by using polypropylene and polyethylene and styrene-ethylene / butylene-styrene block copolymer. The infusion bag manufactured by adopting the technical scheme has the advantages that: the air-tightness and the steam resistance are excellent, the chemical stability is high, and the infusion bag is suitable to be used for manufacturing liquid medicinal products requiring high-temperature disinfection and sterilization; the transparence is high, and the detection of foreign materials when the infusion bag is produced and used is ensured; the softness is high, the falling resistance is high, the heat-sealing property is high, the high-temperature resistance is high, and the infusion bag can be sterilized at the temperature of 121 DEG C; because the infusion bag does not contain halogens, the infusion bag does not cause any environmental pollution when processed after use; and simultaneously, the barrier property is high, the chemical inertness and the biological inertness are high, the compatibility with medicaments is good, and the infusion bag can be used for packaging various kinds of common fluid, enteral nutrient fluid, parenteral nutrient fluid, dialyzate, flushing fluid, treating type large-capacity injection and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a manufacturing process of a medical transfusion bag. The present invention also relates to the production equipment used in the manufacturing process of the 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.
