Description

A kind of pair of hard tube non-PVC large infusion soft-bag
Technical field
This utility model relates to medical packaging material technology field, particularly a kind of pair of hard tube non-PVC large infusion soft-bag.
Background technology
In the prior art, two hard tube non-PVC large infusion soft-bags roughly have two big types: one type of two hard tube non-PVC large infusion soft-bag of being made up of independent identical two hard tubes; Another kind of two hard tube non-PVC large infusion soft-bags of forming by two hard tubes of combined.Connection tube, the flap of last type freestanding pair of hard tube non-PVC large infusion soft-bag all are separate, process after the transfusion bag through after the two-tube fill, two flaps are respectively installed to independently on two hard tube connection tubes through mechanical force again.The connection tube of two hard tube non-PVC large infusion soft-bags of the one type of combined in back is conjuncted; Promptly identical or two different connection tubes are injection molded into one with two when making connection tube; Or with fill with connection tube with add medicinal integral type connection tube flap and be injection molded into one; After processing transfusion bag according to practical situation through after the two-tube or single tube fill, again through mechanical force with two or flap corresponding be installed to fill with connection tube on.
These two types two hard tube non-PVC large infusion soft-bags add two flaps if desired after fill, its shortcoming is, at first, use the cost of two flaps relatively only to want high with the cost of a flap, two hard tubes of combined especially, and itself cost of raw material is height just; Next, machine-building related in actual production process is all higher with the use cost of parts; The 3rd, owing to be two unlimited connection tubes, the risk of secondary pollution further strengthens in the production process.With connection tube and the two hard tube non-PVC large infusion soft-bags that add medicinal integral type connection tube flap injection moulding all-in-one-piece combined, one of which is because the conjuncted structure of connection tube makes the relatively independent two hard tube connection tube costs of himself cost of raw material want high with fill; They are two years old; Owing to be the version of combined; Though at present country also clearly is not defined as two hard tube big soft infusion bags, and some place expressly qualitative its do not belong to two hard tubes truly, so its price and price are all than really pair hard tube big soft infusion bags are low.
Therefore, how to design the two hard tube non-PVC large infusion soft-bags of a kind of stand alone type, make himself cost lower, make and use equipment cost lower, the secondary pollution risk in the production process is lower, produces and uses saferly, and this is to be badly in need of the technical problem that solves at present.
Summary of the invention
To the deficiency that prior art exists, this utility model technical problem to be solved provides that a kind of simple in structure, good airproof performance, production process are safer, production and use cost are lower, and is two hard tube non-PVC large infusion soft-bags truly.
The technical scheme that this utility model is taked is a kind of pair of hard tube non-PVC large infusion soft-bag of design: be by fill with connection tube, fill with sealing cover, add medicinal connection tube flap and soft bag of bag constitutes, it is described that to add medicinal connection tube flap be that connection tube flap cylindrical shell, sillicon rubber blocking and sealing member by integral type constitutes; Described connection tube flap cylindrical shell is to be connected in sequence 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.
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 adopts the integral type that connection tube and flap are united two into one to add medicinal connection tube flap, can effectively avoid external environment condition in the production process to the pollution of medicinal liquid, has solved the problem of existing soft bag infusion existence; 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 bulge-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 to add medicinal connection tube and flap injection moulding all-in-one-piece form, simplified the structure of product greatly, reduced the consumption of material, 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.
