Description

A kind of mixed medicine interface

Technical field

This utility model relates to a kind of mixed medicine interface, belongs to manufacture technology field of medical appliance.

Background technology

When the injectable powder that uses the cillin bottle splendid attire, lyophilized injectable powder or aqueous injection, need liquid medicine in the transfusion flexible bag or water for injection to be extracted out in the injection cillin bottle through syringe, repeat above-mentioned work, enough medicinal liquids are arranged in cillin bottle; And then cillin bottle shaken the medicament mix homogeneously in bottle repeatedly, the reuse syringe is extracted the cillin bottle inner liquid medicine out and is injected transfusion flexible bag, so repeatedly, till the medicinal liquid in bottle is exhausted.Above-mentioned mixed medicine operating process is more time-consuming, effort, take consumptive material such as syringe, and very easily causes the secondary pollution of medicinal liquid.

The patent No. is the patent of ZL200520052561.2, provide a kind of solve the problems of the technologies described above be welded on the mixed medicine interface on the transfusion flexible bag, the advantage of this mixed medicine interface is: when mixing medicine; Do not need repeatedly from transfusion flexible bag, extract liquid medicine, but cillin bottle is placed on the mixed medicine card body that mixes the medicine interface, foldable handle fractures; Make cillin bottle pass through needle cylindrical unit and be communicated with transfusion flexible bag, the soft bag of light then pressure infuser injects cillin bottle with liquid medicine; Again cillin bottle is placed eminence behind the mix homogeneously; Push transfusion flexible bag repeatedly and get final product, simple to operate, practice thrift consumptive material.But this mixed medicine interface also has many deficiencies, its weak point mainly contain following some: 1, the foldable handle of said mixed medicine interface is positioned at transfusion flexible bag; In use, behind the foldable handle that fractures, folding handle section is very easily fallen in the transfusion flexible bag; Foldable handle can produce plastic particles and pollute the medicinal liquid in the transfusion flexible bag when fractureing simultaneously, and in the process that fractures; Because the toughness of the PP plastics that foldable handle uses; Cause breaking force bigger, when operation of fractureing be as easy as rolling off a log exposes transfusion flexible bag, and transfusion flexible bag can't be used; 2, fixedly the sealing of the mixed medicine card body of cillin bottle is to adopt gripper shoe is pasted on the protecting film; Be bonded in through binding agent again that the open end that mixes medicine card body realizes; Like this, protecting film is easy to drop in storage and transportation, causes and mixes the intravital needle cylindrical unit pollution of medicine card; Simultaneously, binding agent itself also can cause the pollution that mixes medicine card body.Again because this technological needle cylindrical unit adopts is polypropylene material; Make it be difficult to reach the effect that pierces through XiLin bottle cap smoothly in actual use; And this needle cylindrical unit and combining nozzle be package assembly, and be loosening easily or drop in transportation or use, causes leakage and pollution.In addition; The connection base of said mixed medicine interface be designed to that surface portion is smooth, seat two ends, end Pedicellus et Pericarpium Trapae sharp ship type structure, such structure with the welding process of transfusion flexible bag in employed welding temperature higher, " the crossing weldering " of causing soft bag easily; Have a strong impact on sealing property; Cause leakage, and sharp corner angle very easily damage transfusion flexible bag itself in the storage of medicine, transportation, bring leakage and raw-material waste equally easily.

To fall in the transfusion bag easily after above-mentioned foldable handle is fractureed in order overcoming, or to puncture the problem of transfusion bag when fractureing easily, in the prior art; According to medicine mixing mouth and the construction features that hard double nip is connected through sealed rubber pipe, also have foldable handle is arranged on the terminal structure of needle cylindrical unit in the sealed rubber pipe, the shortcoming of this structure mainly is; In use; Foldable handle is positioned at the bottom of transfusion flexible bag, and liquid can get into and mix the medicine passage like this, opens even without the foldable handle that fractures and mixes the medicine passage; Foldable handle also can be immersed in liquid all the time, increases the risk of secondary pollution.

The utility model content

This utility model technical problem to be solved is: provide a kind of use easy to operate, can prevent effectively that in use existence owing to foldable handle from causing the mixed medicine interface of secondary pollution.

The technical scheme that adopts for solving the problems of the technologies described above is: a kind of mixed medicine interface; Comprise by mixing the medicine mixing mouth that medicine card body and needle cylindrical unit constitute; Also comprise the hard double nip that contains foldable handle, hard double nip is provided with and mixes the medicine passage, and hard double nip and medicine mixing mouth are connected as a whole through being installed in mixed medicine passage with sealed rubber pipe on the needle cylindrical unit; Foldable handle is arranged on the end of the mixed medicine passage in the sealed rubber pipe, and will mix the endcapped of medicine passage.

Further be, also comprise the sealing member that is made up of gripper shoe and protecting film, protecting film is bonded on the gripper shoe; Mix medicine card body and have an open end and a sealed end, needle cylindrical unit is positioned at sealed end; Sealing member cements on the end face of the open end that mixes medicine card body through protecting film, and with this open end sealing, gripper shoe is supported on the medial wall of mixing medicine card body open end.

Further be, foldable handle is made up of folding handle section, and foldable handle is one-body molded with the mixed medicine passage of hard double nip through folding handle section, or is welded to connect through the end of folding handle section with the mixed medicine passage of hard double nip.

The optimal way of such scheme is that the projection on the folding handle Duan Zaiqi cross section of foldable handle is cross or three corner structures.

The beneficial effect of this utility model is: seal through the end that foldable handle is set to the mixed medicine passage in the sealed rubber pipe and mix the medicine passage; Guaranteed to mix after the medicine interface group installs on the transfusion flexible bag; Before the foldable handle that do not fracture; Foldable handle can not be in the liquid, has reduced mixed medicine interface and has in use produced the probability of secondary pollution; Simultaneously,, need not take care when fractureing that foldable handle can puncture transfusion flexible bag in the operating process that fractures because after the group shape accomplished, foldable handle was positioned at sealed rubber pipe, easy to operate, quick.
