Description
Technical field
The present invention relates to infusion solutions packaging field, specifically a kind of once formed type flexible bag interface and there is the transfusion flexible bag of this flexible bag interface.
Background technology
Because packed in flexible pouchy has self-constriction, himself tensile stress medicinal liquid can be relied on to ooze without conduit ventilation during transfusion, air loop need not be formed, greatly can reduce the probability of secondary pollution and cross infection, and packed in flexible pouchy mode has, and to take volume little, lightweight, be convenient to the features such as storage and transport, therefore, the ratio of packed in flexible pouchy mode in infusion solutions packaging is increasing.
Flexible bag interface is one of major constituents of packed in flexible pouchy, avoids the appearance of the situation such as leakage, gas leakage for contact pin.The flexible bag interface of prior art is formed primarily of interface body, inner cap, enclosing cover and pad, although technology maturation, but still has the following disadvantages: the parts one, contacted with medicinal liquid more (interface body, inner cap all contact with medicinal liquid), cause sealing poor; Two, generating process is complicated; Easily leak air when three, plugging and unplugging pin phenomenon, likely occurs secondary pollution problems.
Summary of the invention
Technical assignment of the present invention is for above-mentioned the deficiencies in the prior art, provides a kind of technique simple, and the once formed type flexible bag interface of good seal performance.
The further technical assignment of the present invention is to provide a kind of soft bag with above-mentioned flexible bag interface.
Technical assignment of the present invention realizes in the following manner: a kind of once formed type flexible bag interface, comprise interface body, the plug with loading passage, plug is arranged on interface body end, be characterized in that this end of interface is provided with seal, the internal diameter of described seal slightly larger than described loading passage diameter and form a shoulder at the junction surface of described seal and described loading passage, the inner ring of seal upper end is provided with seal joint, described plug is arranged between seal joint and described shoulder, and is compressed by seal joint and shoulder and be arranged in seal.
Plug, under the effect that compresses of seal joint and shoulder, can reach good sealing effectiveness, even if in the process of inserting or extracting at syringe needle, also there will not be gas leak phenomenon.
In order to avoid plug directly contacts with medicinal liquid, seal dissepiment can be set at shoulder.
Seal dissepiment can be wholely set in interface body one end near plug, also can compress and be arranged between described shoulder and described plug.
In order to increase the dust-proof effect outside seal, can arrange outside seal in seal joint outer end, described outside seal is preferably diaphragm seal, draw ring or foldable handle.
Plug and fit system between described shoulder and described seal joint, and the fit system of seal joint and seal all can adopt various fit system well known in the art, but in order to reach best sealing effectiveness, preferred following fit system:
Described shoulder is provided with sealing projection and/or sealed groove, and the bottom of described plug is provided with sealed groove and/or sealing projection, and plug and shoulder realize closely chimeric by the cooperation of sealed groove and sealing projection;
The top of described plug is provided with sealing projection and/or sealed groove, and the bottom of described seal joint is provided with sealed groove and/or sealing projection, and seal joint and plug realize closely chimeric by the cooperation of sealing projection and sealed groove;
The periphery of described seal joint is provided with sealing projection and/or sealed groove, and the inner headed face of described seal is provided with sealed groove and/or sealing projection, and seal joint is connected with sealing protrusions match by sealed groove with seal.
Conveniently syringe needle insertion or extract, reduce the deformation of plug when inserting or extract operation, and then reduce gas leakage risk, the thickness in the middle part of plug is preferably less than the thickness at plug edge, as concave lens shape.
Described seal joint preferably adopts hard material, can strengthen sealing effectiveness further.
Above-mentioned interface can be used for the packed in flexible pouchy of single infusion channel, also can be applicable to two infusion channel packed in flexible pouchy, concrete structure is as follows: bag has the interface body of loading passage, plug, two interface body are fixedly connected with by conjunction, two plugs are separately positioned on interface body end, be characterized in that interface body end is provided with seal, the internal diameter of described seal slightly larger than described loading passage diameter and form a shoulder at the junction surface of described seal and described loading passage, the inner ring of seal upper end is provided with seal joint, described plug is arranged between seal joint and described shoulder, and compressed by seal joint and shoulder and be arranged in seal.
Described shoulder can arrange seal dissepiment equally.
Structure and the matching relationship of the structure of the parts such as described interface body, plug, seal joint, seal dissepiment and matching relationship and parts each during above-mentioned single infusion channel are identical.
Any one flexible bag interface above-mentioned is welded in transfusion flexible bag side, once formed type transfusion flexible bag can be obtained.
By above-mentioned Application of Interface when the packed in flexible pouchy, first, the seam portion (interface body is away from one end of seal) of interface body is deep in the opening of soft bag side, and the seam portion of interface body and soft bag are welded together, simultaneously by the opening welded seal of the soft bag of this side by the mode of thermal weld; And the opposite side relative with this side opening, be then reserved with fill opening.
Once formed type flexible bag interface of the present invention compared with prior art has following outstanding beneficial effect:
(1) plug compresses and is arranged between seal joint and interface body shoulder, and is cooperatively interacted by sealing projection and sealed groove, avoids plugging and unplugging in pin process the phenomenon that leaks air;
(2) seal dissepiment is set at shoulder, avoids plug and directly contact with medicinal liquid, prevent storage and transportation herb liquid for a long time from occurring degeneration, denaturalization phenomenon;
(3) adopt hard seal joint, and cooperatively interacted by projection and groove between seal joint and seal, make cooperation more tight, sealing effectiveness is better;
(4) thickness in the middle part of plug is less than the thickness at plug edge, the deformation of plug during injectable operation, and then reduces gas leakage risk;
(5) soft packed on after seam interface of the present invention, in soft bag, pour into medicinal liquid by fill opening, can greatly improve fill efficiency, reduce the pollution that the welding of docking port may cause medicinal liquid after fill.
