Description
Technical field
This utility model relates to medical field, particularly relates to a kind of transfusion flexible bag with interface integral structure.
Background technology
At present, transfusion package mainly contains vial, plastic bottle, non-PVC-soft-bag-packaged, vial, in traditional infusion, has exited conventional transfusion gradually produced because cost of transportation, rapid wear easily consumes reason, often concentrates on some on the stricter special kinds of drug compatibility; And plastic bottle because of hardness excessive, in infusion process, without self-constriction function, need therefore passage, easily the pollutant such as the dust in air introduced medicinal liquid, there is certain risk and hidden danger; Soft bag transfusion product is because of better from contractility under regular atmospheric pressure, and easy to use, obtain using more and more widely at hospital terminal, supply falls short of demand in market.
Common interface structure of soft infusion bag is single inlet pipe, double bimouth pipe, has endoporus in interface, in soft bag infusion production process, first bag operation is carried out, then need boil on the nape opposite the mouth pipe in advance to carry out sealing by fusing, recycling mouth pipe carries out liquid medicine filling, and after fill completes, recycling composite cover carries out secondary sealing by fusing.There is many drawbacks in such operating process, one is filling speed because the diameter of mouth pipe is less and cause production efficiency too low; Two be in pouring process easily by medicine liquid spray to interface sealing by fusing face, causing when welding, causing failure welding and welding residue, residual liquid falls into medicinal liquid, occur leakage hidden danger and liquid medicine contamination, three is that sealing by fusing operation is more, and the sealing by fusing time is long, affects integral production efficiency; Four is that packaging material buying is wide in variety, needs mouth pipe and composite cover, store inconvenience, and cost is higher, affects the market competitiveness.Therefore, design and be a kind ofly convenient to fill and transfusion flexible bag convenient for production just seems particularly important.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of transfusion flexible bag with interface integral structure is provided, in soft bag transfusion product production process, avoid from interface mouth pipe liquid drug, by first welding junction general at present and soft bag film, the two-step process again interface and composite cover product being carried out secondary welding changes one-step method into and welds, and directly integrated interface product is welded with soft bag film, then carries out the technical process of fill at soft bag afterbody.Soft bag transfusion product is by arranging special liquid baffle structure in afterbody filling exit both sides simultaneously, eliminates the problem of upper punch liquid medicine contamination filling exit place sidewall in pouring process, ensure that the reliable heat sealing of filling exit.
This utility model provides a kind of transfusion flexible bag, comprise integrated interface 1 and bag 2, integrated interface 1 comprises interface body 3, aluminium-plastic cap 4 and butyl rubber plug 5 and forms, and described interface body 3 coordinates with butyl rubber plug 5, butyl rubber plug 5 and interface body 3 compress by aluminium-plastic cap 4, realize closely cooperating.
Further improvement is: described interface body 3 is provided with three strip solders side 6, there is the gap of 0.8cm ~ 1.4cm between described solder side 6, is provided with reinforcement 7 in the middle part of described solder side 6.
Further improvement is: be provided with filling exit 9 bottom described bag 2, and described filling exit about 9 two ends are provided with heat seal face 8, fill complete after heat close face 8 carry out heat seal close.
Further improvement is: described interface body 3 pipe port place is provided with extension annulus, is convenient to coordinate with the aluminium flake on aluminium-plastic cap 4.
Further improvement is: described filling exit 9 both sides are provided with gear liquid level 10, and be provided with Pig hole 11 in described filling exit 9, Pig hole 11 is in filling exit 9 medium position.
Further improvement is: the tangent plane of described filling exit 9 is trapezoidal, and lower openings is less than upper opening, and when preventing high-speed canning, medicinal liquid splashes, and causes failure welding.
The beneficial effects of the utility model: reduce the welding sequence in soft bag infusion production process by integrated interface, reduce failure welding, hidden danger that welding waste liquid, waste residue drop medicinal liquid, the trapezium structure design of bottom filling simultaneously, avoid the pollution of medicinal liquid to filling exit place sidewall, ensure that the reliability of filling exit heat sealing, for the raising of soft bag transfusion product production efficiency creates condition.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment, only for explaining this utility model, does not form the restriction to this utility model protection domain.
As Figure 1-5, present embodiments provide a kind of transfusion flexible bag, comprise integrated interface, bag.Integration interface is made up of interface body, butyl rubber plug, aluminium-plastic cap; Be provided with filling exit bottom bag, fill completes laggard row heat seal.Interface body and butyl rubber plug realize assembling, and butyl rubber plug and interface body realize closely cooperating by Cover-rolling machine by aluminium-plastic cap.Interface body mouth pipe port has the extension annulus of about 2cm, is convenient to aluminium flake and coordinates with it, prevents soft bag transfusion product steam when autoclave sterilization from entering bag.Interface body solder side is provided with three strip solders side, there is the gap of 1cm between solder side, to reduce materials'use, solder side middle part is provided with width 0.3mm, the reinforcement of height 0.1mm, the failure welding preventing injecting products from causing because of shrink and leakage.Filling exit tangent plane bottom bag is a trapezium structure, and lower openings is less than upper opening, and such structure is conducive to, when high-speed canning, preventing medicinal liquid from splashing, causing failure welding.After fill completes, carry out twice welding, when preventing transfusion from hanging there is crackle and cause gas leakage in solder side.Exist between upper and lower two hot threads of filling exit and be provided with Pig hole, Pig hole is in filling exit medium position, correspondingly outside high frequency sealing edges both sides is provided with two little Pig holes, to reduce the material usage of filling exit place bag side edge.
In actual production process, being made into one interface 1 in advance, integrated interface 1 is made up of interface body 3, aluminium-plastic cap 4, butyl rubber plug 5, and interface body 3 is provided with three solders side 6, and solder side is provided with reinforcement 7.In production, injection mo(u)lding interface body in advance 3, first combines it with butyl rubber plug 5, then closely cooperates with it with aluminium-plastic cap 4 on Cover-rolling machine, complete integrated interface 1 and combine.Make bag 2 again, integrated interface 1 is welded with bag 2, then carry out liquid drug, medicinal liquid enters in bag by filling exit 9, and filling exit 9 both sides are provided with two corresponding gear liquid levels 10, this structure can prevent liquid splash to heat seal face 8 very well, prevent failure welding, after fill completes, carry out heat seal face 8 and close, this heat seal face is twice heat seal, is provided with Pig hole 11 between two heat seal faces.
