Problems solved by technology

[0006] At present, self-shrinking infusion bags are directly produced by injection stretch blowing process using modified polypropylene pellets. Since the bag system is blown into one piece, the bag body is seamless and there is no mechanical weakness. There is no "multi-layer co-extruded infusion bag" The problem of bag cracking during sterilization or transportation

Abstract

The invention discloses an upright polypropylene soft bag ingredient, which comprises the following components in parts by weight: 85-90 parts of polypropylene, 5-10 parts of styrene-ethylene-butene-styrene copolymer, 3-10 parts of ethylene-propylene copolymer, 0.8-1.2 part of mannitol, 0.1-0.2 part of antioxidant, 0.1-0.2 part of hydrotalcite.

Description

technical field [0001] The invention relates to the technical field of medical transfusion bags, in particular to ingredients for upright polypropylene soft bags. Background technique [0002] Large infusion, that is, terminally sterilized large-volume injection, has a wide range of clinical applications and a large clinical dosage. It is a commonly used and essential drug for rescuing and treating patients. The infusion enters the blood circulation of the human body in the form of infusion through the intravenous route, and its therapeutic effect is remarkable, the onset of effect is rapid, and the clinical dosage is large. Large infusions can be roughly divided into five categories according to their clinical functions: infusions for body fluid balance, infusions for blood volume expansion, infusions for nutrition, infusions for therapeutic drugs, and dialysis contrast agents. Infusion products have developed rapidly in my country over the past ten years. Large infusions ...
