Description
Technical field
The present invention relates to a kind of mixed medicine interface, especially relate to a kind of dustproof medicine interface that mixes, belong 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.
Summary of the invention
Technical problem to be solved by this invention is: a kind of contaminated dustproof medicine interface that mixes that in manufacturing, storage and transportation, is not easy is provided.
The technical scheme that adopts for solving the problems of the technologies described above is: a kind of dustproof medicine interface that mixes; Comprise hard double nip, hard double nip is provided with and mixes the medicine passage, also comprises the medicine mixing mouth that contains closed end cap; Medicine mixing mouth is made up of mixed medicine card body and needle cylindrical unit; Mix medicine card body and have an open end and a sealed end, needle cylindrical unit is positioned at sealed end, and hard double nip is connected as a whole with medicine mixing mouth through mixing the medicine passage with needle cylindrical unit; The dismountable open end that mixes medicine card body that is installed in of closed end cap, and with this open end sealing.
Further be; Also comprise the foldable handle that contains socket section and folding handle section; The mixed medicine passage of hard double nip and the needle cylindrical unit of medicine mixing mouth connect into an integral body through sealed rubber pipe, and the socket section of foldable handle is socketed in the end of the needle cylindrical unit in the sealed rubber pipe, and folding handle section is arranged in sealed rubber pipe.
The optimal way of such scheme is, closed end cap has an opening and a blind end, and closed end cap is connected to the open end that mixes medicine card body through the buckle that is arranged on the opening medial wall.
The optimal way of such scheme is, closed end cap has an opening and a blind end, and closed end cap is screwed in the open end that mixes medicine card body through being arranged on the screw thread on the opening medial wall.
Further be that closed end cap is formed by the aluminum alloy materials compacting or be disposable injection molded by pharmaceutical polypropylene.
The invention has the beneficial effects as follows: through one dismountable closed end cap being set at the open end that mixes medicine card body; With said open end sealing,, in seal process, do not need binding agent because this closed end cap does not adopt bonded structure; Thereby guaranteed that mixed medicine interface can not produce secondary pollution in manufacture process; Just because of closed end cap is not to be bonded on the end face of the open end that mixes medicine card body through binding agent, thus mix the medicine interface store with transportation in be not easy to be damaged, thereby make dustproof mixed medicine interface of the present invention; In the process that stores and transport, also be not easy because of the damage of the obturator that constitutes by closed end cap contaminated.
