Description
Technical field
This utility model relates to technical field, particularly a kind of polypropylene infusion bag with bivalve Easy-folding composite cover.
Background technology
Infusion is the Therapeutic Method inputting various sterile solutions or medicine either directly through vein, because its onset is rapid, determined curative effect, and one of becomes Therapeutic Method basic and the most the most frequently used in modern clinical treatment.
Infusion is developed so far existing nearly 180 years history: make a general survey of the clinical practice of infusion products, and venous transfusion mode goes through three changes: from full open model to semi open model, then arrives total closed type.
Existing large transfusion flexible bag or the wrapping Welding type composite cover of bottle have two kinds of forms, one is made up of enclosing cover, Nei Sai and inner cap, cover outward draw ring, during use need to by draw ring firmly pull-up thus enclosing cover is pulled open together with draw ring connecting portion expose in hole of threading a needle beyond the Great Wall, liquid medicine is injected in bag or bottle, or the liquid medicine in bag or bottle is injected by transfusion device in the blood of people. The Main Function of interior plug is that medicine will not ooze out outside transfusion bag or bottle because inner cap is worn out by needle tubing when injection. But it is all different with to place and the time of patient infusion owing to making up a prescription in use, when entering to infuse to disease, Yin Neisai is exposed the regular hour, likely produce the risk of cross-contamination, therefore must internally fill in exposed part before the injection and disinfect in alcohol, therefore during transfusion, add the cost of sterilization. Another kind of existing pair of easy-to-fold cap, can tear at twice, half be torn when making up a prescription, and second half still seals with enclosing cover, it is torn during transfusion again.
The cost of sterilization can be reduced so in use. Interior plug changes little strip or the circle of changing into, reduces material usage, reduces cost. But plug deposits following point for strip in the composite cover of this structure: 1. in strip, cutting dies is required height when excising slitter edge in manufacturing process by plug, adds the cost of manufacture of interior plug; 2. strip is when syringe needle is injected in bag or bottle by hole of threading a needle, and strip plug easily produces displacement in composite cover, so affects the sealing property of whole composite cover; In the composite cover of this structure, plug deposits following point for circle: plug is easily fallen in bag or bottle when inserting syringe needle.
Close the lid in additionally in prior art and tend to deformation when high-temperature sterilization or subside, cause coordinating between inner cap with plug and enclosing cover to be deformed, it is easy to fit clearance deformation occurs and strengthens the water inlet that causes, and the risk of leakage drug after piercing.
Utility model content
The purpose of this utility model is in that to overcome the shortcoming of prior art, it is provided that a kind of be easy to upright discharge, can airtight from discharge opeing and be easy to operation the polypropylene infusion bag with bivalve Easy-folding composite cover.
The purpose of this utility model is achieved through the following technical solutions: a kind of polypropylene infusion bag with bivalve Easy-folding composite cover, it includes transfusion bag body and the composite cover being connected with transfusion bag body, described transfusion bag body includes bag mouth from top to bottom successively, at the bottom of bag and bag, it it is oval sunken inside structure at the bottom of described bag, the front-back of described bag is connected with arc line shaped with side, described composite cover includes inner cap, enclosing cover and for infuse and make up a prescription time puncture plug, described plug designs for integral type, plug adopts two dolioform structures of circular composition, described plug upper and lower surface is all correspondingly arranged on the first positioning boss and the second positioning boss, described outer cap upper surface is connected to two sets easy to break, the medial surface of cover top portion offers the first groove and the 3rd positioning boss, first positioning boss of described plug upper surface and the first groove fit, matched in clearance between first positioning boss and second positioning boss of the 3rd positioning boss and plug upper surface, described interior cap upper surface is provided with the 4th positioning boss, matched in clearance between first positioning boss and second positioning boss of the 4th positioning boss and plug lower surface.
Described plug is provided with the site of puncture corresponding with set easy to break.
Described inner cap inside top central authorities are provided with a reinforcement.
The height of described bag is 140 ~ 215mm, the width of the center of the front-back of bag is 73 ~ 98mm, the width at the center side place of bag is 42 ~ 54mm, the width at the upper and lower two ends, side of bag is 52 ~ 57mm, the thickness of the front-back of bag is 0.5 ~ 0.6mm, the thickness of the side of bag is 0.2 ~ 0.3mm, and the thickness at the bottom of bag is 0.4 ~ 0.6mm.
This utility model has the advantage that polypropylene infusion bag of the present utility model, the front-back of bag thickeies, hardness is high, strengthen bag, the front-back of bag is connected with arc line shaped with side, arc line shaped serves supporting role, and transfusion bag can be made uprightly to put, thus being conducive to packed and transported, dosing etc. to operate, the side of bag is thin, soft, it is beneficial to contraction, without outer logical air during transfusion, by atmospheric pressure, the front-back compression of transfusion bag is fitted to together, thus draining a bottle inner liquid medicine: the composite cover of setting, in lid manufacture process, cost is low, two thread a needle hole use time mutually do not pollute, inside close the lid and be unlikely to deform and subside, and syringe needle will not be affected by external force and occur that plug moves left and right or fall into the phenomenon in bottle when puncturing, improve risk and defect that existing market product exists, the simultaneously also more perfect correlation function of product, performance, it is that product has safety more.
