Description
Technical field
This utility model relates to medical packaging material technology field, and particularly a kind of non-PVC-soft-bag transfusion adds medicinal integral type connection tube flap.
Background technology
It all is separate producing at present related connection tube, the flap of non-PVC-soft-bag transfusion, and flap basically all combines by lid (and being made up of interior lid, outer cover again mostly), silicone rubber for sealing plug, and its shortcoming is the complex structure owing to flap; Needs at least two, three kind of combination of materials are accomplished and are connected on technology; Required injection mold and operation are also corresponding more, and need special-purpose cover assembling machine that it is combined, thereby its production drops into and production cost is higher; Intermediate link is also many; Pollution risk increases, complex operation and inconvenience, and production efficiency is low.Simultaneously, the production process of non-PVC-soft-bag transfusion all is connection tube to be welded to process transfusion bag on the non-PVC film earlier, with mechanical force flap is installed on the connection tube after pouring into medicinal liquid.Connection tube and flap mainly by the threaded engagement that is in contact with one another face together or through heating be in contact with one another face and sweat soldering together; All there is certain defective in these two kinds of connected modes: the shortcoming of first kind of connected mode is that the connection tube flap leans on the fastness that self is connected not strong; And after flap is opened under external force and assembling connects once more; Its surface does not have obviously damage, and difficult quilt is discovered, and this makes the soft bag infusion product receive the pollution of external factor easily; The shortcoming of second kind of connected mode is because what adopt is contactless heating sealing by fusing technology; Have medicinal liquid on arbitrary contact surface of connection tube and flap, all can cause can't firm welding, thereby; There is leakage hidden danger; And heating plate service time is long slightly falls slag and granule phenomenon, serious harm quality of liquid medicine and drug safety easily.
Therefore, how to design a kind of non-PVC-soft-bag transfusion and add medicinal connection tube flap, make connection tube and flap firm and reliable connection, good airproof performance, and simple in structure, easy to make, safe in utilization, cost is lower, and this is a technical problem of being badly in need of solution at present.
Summary of the invention
To the deficiency that prior art exists, this utility model technical problem to be solved provides a kind of simple in structure, easy to make, good airproof performance, firm and reliable connection, and safe in utilization, lower-cost connection tube flap.
The technical scheme that this utility model is taked is that a kind of non-PVC-soft-bag transfusion of design adds medicinal integral type connection tube flap: be to be made up of connection tube flap cylindrical shell, sillicon rubber blocking and sealing member; Described connection tube flap cylindrical shell is to be fused successively from top to bottom by cylindrical shell step, flap cylindrical shell, transition conduit and connection tube; Seal assemblies is on have the cylindrical shell step of endoporus; The sillicon rubber blocking device forms sealant between the bottom surface of blind hole and the transition conduit in this in the interior blind hole of flap cylindrical shell.
Described sealing member is plastic foil or aluminum-plastic composite membrane.
Interior blind hole top at said flap cylindrical shell is provided with the ring-type bulge loop.
Described ring-type bulge loop, its cross section are a kind of in arc or waveform or zigzag or trapezoidal or trapezoidal or hemispherical or the triangle that tilt or the facet that is interrupted setting.
Described ring-type bulge loop, its bump sizes are 0.2～0.8mm.
described ring-type bulge loop, its bump sizes is 0.3～0.5mm.---unnecessary deletion
The gauge of the sealant that between the interior blind hole bottom surface of said flap cylindrical shell and transition conduit, forms is 0.3～0.5mm.
Described sillicon rubber blocking, its end face middle part is made as circular concave, and the middle part, bottom surface is made as pit.
Also be provided with the ship shape piece at described connection tube position.
Described connection tube is the flat pipe of elastic closure.
Also be provided with diamond block at described connection tube position.
The section at said connection tube position can be circle or rhombus or ellipse or ship shape or other shape.
This utility model advantage compared with prior art, its beneficial effect is following:
The one, this utility model is through being injection molded into one with connection tube and flap cylindrical shell, and after the assembling, connection tube and flap unite two into one, and can effectively avoid the pollution of external environment condition to medicinal liquid, has solved the problem that existing soft bag infusion exists; Simultaneously, can further increase sealing, the air-tightness of infusion products and the firm reliability that is connected, improve the safety of soft bag infusion product quality.
The 2nd, (that is: the interior blind hole top of flap cylindrical shell) is provided with the annular projection structure on the circular inner sidewall of connection tube flap upper end; In the time of can preventing after using dosing, to pull out pin the sillicon rubber blocking in the endoporus is taken out of together; Compare with existing product; Increase the fastness of sillicon rubber blocking, improved the soft bag infusion clinical application safety.
The 3rd, adopt connection tube and flap injection moulding all-in-one-piece form, simplified the structure of product greatly, also saved many intermediate links, simple for production, be convenient to production operation, greatly reduce production cost.
The 4th, be employed in the top device sealing member of connection tube flap cylindrical shell, the sterilization back be an aseptic condition, thus do not need to disinfect again during use, thereby, compare with existing product, use more convenient.
The 5th, with the end face of sillicon rubber blocking middle part be made as circular concave, the middle part, bottom surface is made as pit, compares with existing product, is convenient to the insertion of transfusion needle.
