Problems solved by technology

The production process requires the preform to be manufactured first, stored for 5-12 hours, and then heated on a professionally manufactured bottle blowing machine, blown into shape with high-pressure compressed air, and finally a lifting ring is made and welded on the tail. The manufacturing process requires It is very cumbersome to complete it on three machines. If the infusion bottles for packaging medicines are not handled well in every production link, it will cause pollution to the medicines
A large investment and high manufacturing costs
In addition, when plastic bottles are used, they need to be exhausted, which is easy to cause secondary pollution

Abstract

The invention relates to a blow molding medical bag and a preparation method thereof. The blow molding medical bag includes a bag body. One end of the bag body is provided with a convex filling opening and the other end is provided with a lifting ring. The bag body, the filling opening and the lifting ring form an integral structure. The preparation method includes: taking medical polythene, medical polypropylene or medical modified-polypropylene as the raw materials and adopting a hollow blow molding method and a hollow blowing device to carry out one-time blow molding on the medical polythene, the medical polypropylene or the medical modified-polypropylene to acquire the blow molding medical bag. The blow molding medical bag has the advantages of reasonable structure, being convenient for mechanized filling and packaging, effectively preventing a loaded liquid from leaking and divulging. The invention can not only ensure the pollution free property during the filling and packaging processes, but also realize high speed manufacture with low cost, thus solving a plurality of defects existed in the existing perfusion bag of non PVC materials and polypropylene perfusion bottle. The preparation method can realize industrialized and mechanized manufacture and automatic filling and has the advantages of low cost and high output.

Description

technical field [0001] The invention belongs to the technical field of plastic packaging materials and products for medical transfusion products, and in particular relates to a blow-molded medicinal bag that can replace non-PVC films to manufacture transfusion soft bags and a method for preparing the blow-molded medicinal bag. Background technique [0002] At present, my country produces about one billion bottles of infusion per year, most of which are glass bottles and a small part are plastic bottles. However, glass bottles and plastic bottle packaging have common defects such as easy contamination during use, which brings potential problems to clinical medication. hidden dangers. At present, the infusion solution in plastic bags develops rapidly because of its advantages of simple manufacture, small production area, light weight, pressure resistance, convenient transportation, fast infusion and less pollution during infusion. It turns out that the vast majority of domesti...
