The large transfusion flexible bag of integrated strip tee pipe three valves, bottle packaging plastic double-color cover
Technical field
The present invention relates to field of medical products, be specifically related to deposit bag, the bottle of medicinal liquid.
Background technology
At present, be used for patient's transfusion bag, bottle infusion port, generally all be provided with composite cover, this composite cover be by enclosing cover, inner cap and be pressed between enclosing cover, the inner cap, the plug filled in the enclosing cover blind pipe consists of.Enclosing cover, the inner cap of existing composite cover are polypropylene material, and what plug adopted is polyisoprene.The production process of existing composite cover is packing separately behind enclosing cover, inner cap, capsule forming, is pressed into lid by manually sending into the cover assembling machine group again, becomes the finished product composite cover after qualified by manual detection.From the foregoing, existing composite cover exists following defective:
The one, production process is many, the cycle is long, cost is high; The 2nd, cover in the process because of the fricative powder of enclosing cover and cover assembling machine and the air-flow of used air compressor machine and can pollute composite cover in group; The 3rd, be combined in lid together by three's (being enclosing cover, inner cap, plug), in use because problems such as cooperation closely can not leaked gas, leakages.
The 4th, because plug adopts polyisoprene rubber, its molecular structure is near natural rubber, it is a kind of elastomeric material that synthesizes and carried out improvement according to the natural rubber structure, has the characteristic that some is better than natural rubber, but because due to the difference of its microstructure, crystal property is lower than natural rubber, and ageing properties is poorer than natural rubber, though sulfur form is substantially similar to natural rubber, but curingprocess rate is slow, sulfuration lacks the effect of bound sulfur, and the problem of therefore bringing with the plug of this material is: easily medicine is produced pollution, its breathable moisture permeability of what is more important is good, easily cause medicine rotten, self sealss poor performance after the puncture, easily leakage also has, because the density of material is low, in the piercing process, have bits, microgranule is taken out of into the liquid, exists larger potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of large transfusion flexible bag, bottle packaging plastic double-color cover of integrated strip tee pipe three valves, the technical problem that will solve simultaneously provides the large transfusion flexible bag of this double-tube double-valve, the valve plug of bottle packaging plastic double-color cover is made material, the production process that overcomes the prior art existence is many, cost is high, the gas leakage in the use, leakage and the defectives such as liquid medicine contamination that cause in production, storage, use procedure.
The present invention is achieved through the following technical solutions:
The large transfusion flexible bag of integrated strip tee pipe three valves, bottle packaging plastic double-color cover, comprise lid, protrude from the blind pipe of cap top, be arranged at the valve plug in the blind pipe, also comprise the foldable handle that is arranged at the blind pipe end face, described cap top has three blind pipes that are provided with valve plug, and lid, valve plug are overall structure, connect as one by injection moulding.
The further improvement project of the present invention is, the blind pipe opening direction is consistent with the lid opening direction, or the opening of blind pipe is positioned at blind pipe one side, and its opening direction is parallel with cap top.
When the blind pipe opening direction is consistent with the lid opening direction, the blind pipe inner top surface is provided with the reinforcement (described blind pipe inner top surface does not comprise that part of cracking-off when using) that is connected with valve plug, described reinforcement downward projection is rounded, cross or be latticed, or described reinforcement is the projection that is arranged at the blind pipe inner top surface.
The present invention further improvement project is that foldable handle is parallel or perpendicular to the cap top setting, foldable handle is provided with pictorial symbolization or the word marking that makes up a prescription and infuse; Or foldable handle is provided with the pictorial symbolization of making up a prescription and infusing, and stays in the opening shape of blind pipe end face consistent with the pictorial symbolization that foldable handle is provided with behind the foldable handle cracking-off.Described pictorial symbolization can be used rectangle, circle, triangle etc., and word marking can be distinguished with make up a prescription, transfusion etc.Described figure or word marking protrude or are depressed in the foldable handle plane layout.
Be used for the large transfusion flexible bag of above-mentioned integrated strip tee pipe three valves, the valve plug of bottle packaging plastic double-color cover, described valve plug adopts TPO TPE material.
Compared with prior art, the present invention has following obvious advantage:
One, the present invention adopts TPO TPE as the valve plug material, TPO TPE, be that a class has the general-purpose plastics processing characteristics, but product there is the macromolecular material of similar cross-linked rubber performance, combines the performance of rubber and good machinability.Its environmental-protecting performance is outstanding, nontoxic, tasteless, recovery rate 100 ﹪.This valve plug and drug compatibility are good, in the liquid medicine storage process, can not cause medicine rotten, and finished product has the advantage of high resiliency, high scalability, during puncture, can exfoliation, leakage, can security seal after the puncture, solved preferably the pollution problem that the leakage of puncture exfoliation brings to medicine, clinical safety in utilization improves greatly.
Two, the present invention is owing to lid, valve plug all adopt plastic material, therefore, can injection mo(u)lding on same injection machine, lid and valve plug are become one, not only solved the pollution problem that prior art group lid production process is brought, also overcome the defective such as gas leakage, leakage of manufactured goods, and greatly shortened production process, reduced production cost.
Three, the present invention make up a prescription pipe valve and the transfusion pipe valve foldable handle be provided with the sign that makes up a prescription or infuse, during use according to exposing valve plug behind labelling cracking-off handle, make up a prescription and infuse the convenience, safe and reliable, pollution, the leakage of having avoided repeated puncture to bring.
