Abstract
The utility model is a composite membrane for making the intravenous transfusion medicine container bag. The cross section of the composite membrane includes the following sequentially ranging from the inner layer contacting the transfusion medicine to the outer layer contacting the air: inner modified propylene copolymer(1), middle modified propylene copolymer (2)and outer modified propylene copolymer (3). The total thickness of the inner modified propylene copolymer(1), middle modified propylene copolymer (2)and outer modified propylene copolymer (3) is 170mum-210mum. The inner modified propylene copolymer of the utility composite membrane can protect the medicine without any side effects, the middle modified propylene copolymer can shield the vapor and improve the product's flexibility, and the outer modified propylene copolymer has outstanding performance of high-temperature sterilization. The transfusion medicine container bag made of this utility model has no side effects for the transfusion medicine, guarding against the steam with good utility, flexibility and high-temperature sterilization performance.
Description
Technical field:
This utility model is a kind of used composite membrane of intravenous medicine packaging bag of making, and belongs to the renovation technique of the used composite membrane of intravenous medicine packaging bag.
Background technology:
The intravenous medicine packing container that generally uses at present is vial, the shortcoming of its existence is not only easily broken, the inconvenience transportation, and the storage volume is big, and in use owing to need constantly to introduce air in medicinal liquid, dust in air, microorganism are easy to cause the pollution once more of medicinal liquid.For this reason, external most of fine plastic bottle and plastic bag of adopting is as the intravenous medicine packing container, but the used composite membrane of its plastic packaging bag is to adopt flexible PVC (PVC) to make, because PVC will add various auxiliary agents in the course of processing, micromolecule auxiliary agent migration and PVC self with the chlorine element make it from being worked into removal process, the capital discharges harmful components, is detrimental to health.Other has some composite membranes is to adopt non-PVC to make, but its combination property is all not good enough, and some composite membrane is bad to the high barrier of water vapour, and some is that pliability is not good enough, and some is that high temperature-resistant disinfected performance is undesirable.
The utility model content:
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of not only without any side effects to flow of infusate, and water vapour had high barrier, have good practicality and pliability, has outstanding high temperature-resistant disinfected performance, the three-layer co-extruded intravenous medicine packaging composite film of good comprehensive properties.
Structural representation of the present utility model as shown in Figure 1, the cross section of composite membrane include successively from the internal layer of contact flow of infusate to the skin that contact with air interior modified copolymer propylene layer (1), modified copolymer propylene layer (2), outer modified copolymer propylene layer (3).
The gross thickness of modified copolymer propylene layer (1), middle modified copolymer propylene layer (2), outer modified copolymer propylene layer (3) is 170 μ m～210 μ m in above-mentioned.
The thickness of modified copolymer propylene layer (1) is 20 μ m～25 μ m in above-mentioned.
The thickness of modified copolymer propylene layer (2) is 133 μ m～164 μ m in above-mentioned.
The thickness of above-mentioned outer modified copolymer propylene layer (3) is 17 μ m～21 μ m.
The cross section of this utility model composite membrane include successively from the internal layer of contact flow of infusate to the skin that contact with air interior modified copolymer propylene layer, the structure of modified copolymer propylene layer, outer modified copolymer propylene layer; interior modified copolymer propylene layer provides the outstanding protectiveness to flow of infusate; without any side effects; in modified copolymer propylene layer the function of outstanding obstruct water vapour is provided and increases the pliability of product, outer modified copolymer propylene layer provides outstanding high temperature-resistant disinfected performance.Not only without any side effects with the intravenous medicine packaging bag that this utility model is made to flow of infusate, water vapour had high barrier, and can damp and hot sterilization under 121 ℃ condition, also can adopt the gamma ray sterilization, and in subzero 10 ℃ to 121 ℃ very wide serviceability temperature scopes, have good practicality and pliability, and be totally enclosed infusion model, avoid the pollution once more in the infusion process.The intravenous medicine packaging bag of making of this utility model meets the every chemical property and the biology performance index of intravenous medicine packaging bag, can be used for packing venous transfusions such as saline, glucose, dialysis solution, flushing liquor.
