Description
Technical field
The present invention relates to a kind of non-PVC composite membrane transfusion soft bag.
Background technology
Widespread usage along with infusion treatment, infusion model has passed through from open, semi open model to fully closed evolution, and transfusion device is thereupon by the vial that begins, to the soft bag of polrvinyl chloride (PVC), to polypropylene, polyethylene (PP/PE) duroplasts bottle, so far advanced in the world and meet the soft bag of non-PVC composite membrane of environmental protection fully.
There is following problems in traditional infusion vessel: 1, vial: vial has good transparency, the compatibility and reaches water resistance gas performance, make vial transfusion obtain unprecedented development, this also is why glass bottle packaging can develop into now and occupy one of the reason in certain market.But because vial can not be flat flat, so need not the cracked ends vent line in solution, to introduce air generation pressure in the infusion process, and dust in air, microorganism (as antibacterial, fungus etc.) can enter in the vial thus, cause the pollution of transfusion.Studies show that the contaminated probability of venous transfusion that is exposed to hospital ward is to be exposed to 10 times of toilet, there are many reports that cause complication such as infection in using bottled infusion process in countries such as the U.S., and at home, this situation is also quite a lot of sees.In addition, when adding curative drug (as easy oxidation antibiotic, antitumor drug etc.) instillation for a long time in the medicinal liquid, medicine constantly contacts with air, can cause that part drug level and drug effect reduce, and weaken curative effect.Vial self is great, deposits that to take volume big, and the making of vial itself also is a highly energy-consuming and contaminated environment process.2, the soft bag of PVC: the soft bag of PVC, solved the air pollution problems inherent of former bottled semi open model transfusion clinically, mainly from PVC itself and environmental protection worker's opposition, WHO stipulates its shortcoming: buried after the processing of disposable infusion articles for use: a, the sterilization, and b, the thorough burning.PVC burns the back and produces organochlorine destruction atmosphere, contaminated environment.In order to increase the intensity of PVC material, in the PVC material, added a kind of plasticizer (DEHP) in the production process, this plasticizer seepage is dissolved in the medicinal liquid, and long-term storage influences the inherent quality of medicinal liquid, and patient's life-time service easily influences its hemopoietic function; Itself also has breathability and permeability the PVC material, brings great difficulty for the link of sterilizing in the preparation, and sterilising temp control is bad, can make transfusion bag suction whiting and opaque, and products storage need add outer package.In addition, also exist microgranule to come off in the PVC material, influence the clarity of product, human body is produced harm.This material all can produce chlorine or the like in production and destruction process, therefore, from present concrete condition, the transfusion bag of PVC material is not a kind of ideal bottled transfusion succedaneum, can only be a kind of cambic succedaneum.3, plastic infusion bottle (PE/PP): compare with vial, plastic bottle is except weight saving, with medicinal liquid the good compatibility is arranged also, anti-crushing property also is that vial is incomparable, and plastic bottle does not equally have environmental issue yet, but aspect infusion model, do not overcome the defective of vial, can not reply fully after the medicinal liquid emptying, need air inlet, thereby can cause bottle possibility that interior microgranule increases.Also have sterilization back poor transparency etc., in addition, the material of plastic infusion bottle is a homogeneous material, mostly is polypropylene (PP), polyethylene (PE) at present.The low temperature resistivity of polypropylene (PP) material can be bad, and when temperature reduced, the anti-fragility of polypropylene containers also decreased, and is unfavorable for transporting at low temperatures; Polyethylene (PE) material can not be high temperature-resistant disinfected, is no more than 110 ℃ usually.Therefore, the development of duroplasts bottle also is restricted.Use also few in the market.
And when existing transfusion flexible bag sealed after adding medicinal liquid in the bag, its hermetically-sealed construction was unreasonable, unusual waste material, and the cost height, and make that in seal process liquid medicine is polluted easily, sealing effectiveness is bad.
Summary of the invention
Technical problem to be solved by this invention provide a kind of to thermally-stabilised, environmental protection,, good sealing effect pollution-free to medicinal liquid, be convenient to transport the non-PVC composite membrane transfusion soft bag of storage.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: non-PVC composite membrane transfusion soft bag, comprise that the mouth that the transfusion bag of being made by non-PVC composite membrane, an end and transfusion bag opening with opening cooperates manages, have the stage body that the bead caliber outwards convexes on the described mouthful of pipe outer wall, the other end of mouthful pipe protrudes from stage body; Described mouthful pipe place also is provided with the part hollow circular cylinder of fit mutually that protrudes from stage body with mouthful pipe, constitutes a cavity between hollow circular cylinder and mouthful pipe outer wall, and hollow circular cylinder one end and stage body are tightly connected, and it is contour that the other end and mouth pipe protrude from the part of stage body.
Also comprise the seal cover that is complementary with mouthful pipe, described seal cover is managed diameter, is constituted less than the hollow cylinder of hollow circular cylinder and with top cover that hollow cylinder one end is tightly connected greater than mouth by a diameter, described hollow cylinder outer wall is provided with at least one sealing ring, sealing ring and cavity inner wall interference fit when the hollow cylinder of seal cover places cavity.
Also comprise the seal cover that is complementary with mouthful pipe, described seal cover is managed diameter, is constituted less than the hollow cylinder of hollow circular cylinder and with top cover that hollow cylinder one end is tightly connected greater than mouth by a diameter, described hollow cylinder inwall is provided with at least one sealing ring, sealing ring and cavity inner wall interference fit when the hollow cylinder of seal cover places cavity.
Also comprise the seal cover that is complementary with mouthful pipe, described seal cover is managed diameter, is constituted less than the hollow cylinder of hollow circular cylinder and with top cover that hollow cylinder one end is tightly connected greater than mouth by a diameter, described hollow cylinder outer wall and inwall are provided with at least one sealing ring, sealing ring and cavity inner wall interference fit when the hollow cylinder of seal cover places cavity.
