Technical field
This utility model relates to a kind of powder-liquid double-chamber transfusion bag of spicing forming type.
Background technology
Powder-liquid double-chamber transfusion bag product is a kind of immediate dispensing infusion product, packaging material powder-liquid the double-chamber transfusion bag of this series products means and is combined into bag surrounding by multilayer co-squeeze film for transfusion by real welding heat, is separated with weak welding heat conjunction (can exert pressure and open) transfusion bag made inner space, and two chambers of this transfusion bag can be respectively used to liquid drug and aseptic powder.Before transfusion, operator only need apply certain pressure to sap cavity bag, is opened at weak weldering position and makes two chambers through and shake up, thus make sterile liquid medicine and aseptic powder fully mix and dissolve, and can carry out clinical transfusion subsequently by after the suspension of this transfusion bag.Compared with traditional infusion bag, powder-liquid double-chamber transfusion bag has following advantage on Clinical practice: (1) clinical treatment is without error of making up a prescription, and prevents nosocomial infection, without the need to special sterile dispense chamber when making up a prescription, uses very convenient, safety; (2) significantly can shorten incorporation time of making up a prescription, improve medical personnel's work efficiency; (3) can reduce the storage area of medicine in intermediate links and medical institutions, reduce Biohazard Waste; (4) be specially adapted to speedily carry out rescue work, the disaster relief, emergent, field relief, the occasion such as war.
The manufacture of powder-liquid double-chamber transfusion bag need adopt dedicated film material, common multilayer co-squeeze film for transfusion cannot use owing to can not realize weak weldering, at present, on medical packaging market, the film material that can be used for manufacturing powder-liquid double-chamber transfusion bag mainly contains two kinds: one is internal layer material is poly multilayer co-squeeze film for transfusion; Another kind is internal layer material is polyacrylic multilayer co-squeeze film for transfusion.Above-mentioned two kinds of film materials all can realize weakly being welded the powder-liquid double-chamber transfusion bag produced and meet Clinical practice requirement.
Although above-mentioned two kinds of dedicated film materials can realize weak being welded and produce powder-liquid double-chamber bag, but limit the scope of application because of the defect of respective material own, wherein, internal layer material is that poly film material and most of powder injection formulation compatibility are better, go on the market for many years in Japan, but due to the terminal sterilization (as: 121 DEG C, 12 minutes) that it can not tolerate injection requirement, cannot promote the use of at home; Internal layer material be polyacrylic film material then because polypropylene material itself is containing large weight oligomers, not good with most of powder injection formulation compatibility, and use limited.
Utility model content
For prior art Problems existing, primary and foremost purpose of the present utility model is the powder-liquid double-chamber transfusion bag providing a kind of spicing forming type, and quasi-solution certainly existing powder-liquid double-chamber bag product causes because of the defect of film material material own using limited problem.Secondary objective of the present utility model is the preparation method of the powder-liquid double-chamber transfusion bag providing a kind of spicing forming type.
For achieving the above object, technical solution of the present utility model is:
A kind of powder-liquid double-chamber transfusion bag of spicing forming type, this transfusion bag comprises flour bag and liquid bag, described flour bag is separated by least one weak welding rod mutually with described liquid bag, the bag wall of this transfusion bag is made by being at least provided with inside and outside two-layer PP TYPE material, wherein, the internal layer of liquid bag is made up of polypropylene/modified polypropylene, and the internal layer of flour bag is made up of polyethylene/modified poly ethylene, and the place of joining of the bag wall of liquid bag and the bag wall of flour bag is provided with splicing bar.
Further, described splicing bar is arranged on the side being close to described weak welding rod in described flour bag chamber.
Further, described liquid bag is provided with plastic interface, described plastic interface is welded with plastic closure.
Further, be welded with its coated aluminum-plastic composite membrane outside described flour bag, described aluminum-plastic composite membrane offers suppending hole.
A preparation method for the powder-liquid double-chamber transfusion bag of above-mentioned spicing forming type, described preparation method comprises the steps:
1) to get internal layer material be polypropylene/modified polyacrylic PP TYPE material A and internal layer material is the PP TYPE material B of polyethylene/modified poly ethylene, in the two intersection, the side of two kinds of film materials is stacked with, splicing bar is formed by heat seal welding, make splicing film material, wherein, PP TYPE material A and PP TYPE material B has at least inside and outside two-layer;
2) get the splicing film material prepared and make bag blank by heat seal welding, weak welding rod bag inner chamber being separated into flour bag and liquid bag is welded with in the side heat seal being close to described splicing bar, wherein, described liquid bag is surrounded by PP TYPE material A, and described flour bag is surrounded by PP TYPE material B;
3) in liquid bag chamber, pour into medicinal liquid, sterilizing after fill, drying, then inject medicated powder in flour bag chamber, seal after fill.
Further, also comprise step 4) and be welded with its coated aluminum-plastic composite membrane outside flour bag, described aluminum-plastic composite membrane offers suppending hole.
Powder-liquid the double-chamber transfusion bag of spicing forming type of the present utility model solves and is used alone polyethylene or the polypropylene dilemma as chamber internal layer, using polyethylene/modified polyethylene film material as the internal layer of flour bag, film material and medicated powder have the good compatibility, using polypropylene/modified polypropylene screen material as the liquid bag internal layer needing terminal sterilization, the requirement of terminal sterilization can be born, during use, extrude weak welding rod place, weak welding rod is collapsed and convinces logical flour bag and liquid bag by patient analysis, make the aseptic mixing of powder liquid; Arranging the weak welding rod of multiple tracks can avoid at pilot processs such as storage, transports, because missing the problem that pressure infuser bag causes weak welding rod to collapse out; Multilayer bag wall makes transfusion bag more solid, and barrier is better, and can not affect the terminal sterilization of liquid bag; Aluminum-plastic composite membrane meets the requirement that flour bag Chinese medicine powder lucifuge stores, and convenient hanging.
