Description
Technical field
The present invention relates to a kind of powder-liquid double-chamber transfusion bag, and the preparation method of this powder-liquid double-chamber transfusion bag.
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 closed the transfusion bag that (can press and open) separation inner space is made with weak welding heat, and two chambers of this transfusion bag can be respectively used to liquid drug and aseptic powder.Before transfusion, operator only need to apply certain pressure to sap cavity bag, is opened at weak weldering position and makes two chambers through and shake up, so that sterile liquid medicine is sufficiently mixed with aseptic powder and dissolves, can carry out clinical transfusion subsequently after the suspension of this transfusion bag.Compared with traditional infusion bag, powder-liquid double-chamber transfusion bag has the advantage that on Clinical practice (1) clinical treatment, without error of making up a prescription, prevents nosocomial infection, makes up a prescription room without special sterile when making up a prescription, and uses very convenient, safety；(2) can significantly shorten incorporation time of making up a prescription, improve medical personnel's work efficiency；(3) can reduce medicine in intermediate links and the storage area of medical institutions, reduce Biohazard Waste；(4) be particularly well-suited 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 to use 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, can be used for manufacture powder-liquid double-chamber transfusion bag film material mainly have two kinds: a kind of be internal layer material be the multilayer co-squeeze film for transfusion of polyethylene；Another kind be internal layer material be polyacrylic multilayer co-squeeze film for transfusion.Above two film material all can realize weak being welded and produce the powder-liquid double-chamber transfusion bag meeting Clinical practice requirement.
Although above two dedicated film material can realize weak being welded and produce powder-liquid double-chamber bag, but limit range because of the defect of respective material own, wherein, internal layer material is that the film material of polyethylene is preferable with the major part powder injection formulation compatibility, list for many years in Japan, but it is not resistant to the terminal sterilization (such as: 121 DEG C, 12 minutes) of injection requirement due to it, cannot promote the use of at home；Internal layer material be polyacrylic film material then because polypropylene material itself is containing big weight oligomers, the best with the major part powder injection formulation compatibility, and use limited.
Summary of the invention
The problem existed for prior art, the primary and foremost purpose of the present invention is to provide a kind of powder-liquid double-chamber transfusion bag, intends to solve that existing powder-liquid double-chamber bag product causes using limited problem because of the film defect of material material own.The secondary objective of the present invention is to provide the preparation method of a kind of powder-liquid double-chamber transfusion bag.
For achieving the above object, the technical solution of the present invention is:
A kind of powder-liquid double-chamber transfusion bag, this transfusion bag includes 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 up of the PP TYPE material at least provided with inside and outside two-layer, 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 internal layer of liquid bag and the internal layer of flour bag is provided with co-extrusion fusion portion.
Further, the side in described co-extrusion fusion portion is close to by weak welding rod described in one or more in being arranged on described liquid bag chamber.
Further, described liquid bag is provided with plastic interface, described plastic interface is welded with plastic closure.
Further, the bag wall of described liquid bag and described flour bag is provided with three layers, is additionally provided with polypropylene/modified polypropylene middle level and polypropylene/modified outer layer of polypropylene outside the internal layer of transfusion bag.
Further, the bag wall of described liquid bag and described flour bag is provided with five layers, outside the internal layer of transfusion bag, it is additionally provided with polypropylene/modified polypropylene middle level and polypropylene/modified outer layer of polypropylene, between internal layer and the described polypropylene/modified polypropylene middle level of transfusion bag, between polypropylene/modified polypropylene middle level and described polypropylene/modified outer layer of polypropylene, accompanies adhesive phase.
Further, outside described flour bag, it is welded with the aluminum-plastic composite membrane being coated with, described aluminum-plastic composite membrane offers suppending hole.
The preparation method of a kind of above-mentioned powder-liquid double-chamber transfusion bag, described preparation method comprises the steps:
1) polypropylene/modified polypropylene fusion pellet and polyethylene/modified poly ethylene are melted after pellet crosses in coextrusion, formed the internal layer of co-extrusion film material by internal layer sub-runner coextrusion, and form co-extrusion fusion portion in the two intersection, the outer layer of co-extrusion film material melts pellet and is extruded into the outer layer of described co-extrusion film material, the most inside and outside two-layer of co-extrusion film material through the outer layer sub-runner of described coextrusion；
2) take the co-extrusion film material prepared and make bag blank by heat seal welding, the weak welding rod that bag inner chamber is separated into flour bag and liquid bag it is welded with in the side heat seal being close to described co-extrusion fusion portion, wherein, the internal layer of described liquid bag is polypropylene/modified polypropylene, and described flour bag internal layer is polyethylene/modified poly ethylene；
3) in liquid bag chamber, pour into medicinal liquid, sterilizing after fill, be dried, then in flour bag chamber inject medicated powder, after fill seal.
Further, the described polypropylene/modified polypropylene fusion pellet in step 1) and described polyethylene/modified poly ethylene melt pellet and are respectively prepared by two pellet extruders.
Further, in described coextrusion, the quantity of sub-runner determines the number of plies of described co-extrusion film material, and it is polypropylene/modified polypropylene that the outer layer of co-extrusion film material melts pellet.
Further, also include that step 4) is welded with the aluminum-plastic composite membrane being coated with outside flour bag, described aluminum-plastic composite membrane offers suppending hole.
The powder of the present invention-liquid double-chamber transfusion bag solves the dilemma being used alone polyethylene or polypropylene as chamber internal layer, using polyethylene/modified polyethylene film material as the internal layer of flour bag, film material and medicated powder have the preferable 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 at weak welding rod, make weak welding rod collapse and convince logical flour bag and liquid bag by patient analysis, make the aseptic mixing of powder liquid；The weak welding rod of multiple tracks is set it can be avoided that at pilot processs such as storage, transports, because pressure infuser bag causes the problem that weak welding rod collapses out by mistake；Multilayer bag wall makes transfusion bag more solid, and barrier more preferably, and does not interferes with the terminal sterilization of liquid bag；Aluminum-plastic composite membrane meets the requirement of flour bag Chinese medicine powder lucifuge storage, and convenient hanging.
