Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of hard double nip that is connected with infusion vessel.
Background technology
In clinical treating disease, perhaps directly medicine is injected in the body often for patient infusion through intravenous drip, medicine often is stored in the transfusion bag, and injection of the medicinal liquid in the transfusion bag or output are usually through hard double nip realization.
In the prior art, hard double nip comprises pedestal, has one on the pedestal and mixes a medicine passage and an infusion channel, mixes the medicine passage and extends the mixed medicine interface that pedestal forms the cylindrical hollow structure, and infusion channel is extended the transfusion interface that pedestal forms the cylindrical hollow structure.
The hard double nip of said structure in use mainly exists following not enough: one, when being connected with medicine mixing mouth, need through hose connection, an end of flexible pipe is enclosed within and mixes on the medicine interface; And with this mixed medicine interface seam; The other end of flexible pipe is enclosed within on the needle cylindrical unit on the medicine mixing mouth, and with this needle cylindrical unit seam, so both increased the installation station of flexible pipe; Increase the welding position again, increased probability because of welding position leakage when mixing medicine; Two, hard double nip is connected with medicine mixing mouth through flexible pipe, because of the restriction of material that flexible pipe adopts, in temperature lower (like zubzero temperature), is prone to cause the welding position cracking of flexible pipe, and then causes mixing the medicine leakage; Three, the hard double nip of said structure when being connected with medicine mixing mouth through flexible pipe, also need be installed foldable handle in the flexible pipe.
The utility model content
To the above-mentioned deficiency that exists in the prior art, this utility model provides a kind of in use need not to adopt foldable handle and flexible pipe, avoids mixing the medicine leakage because of welding produces, and reduce station is installed, and the hard double nip of one-time formed plug-in.
In order to solve the problems of the technologies described above; This utility model has adopted following technical scheme: the hard double nip of plug-in; Comprise pedestal, have one on the said pedestal and mix a medicine passage and an infusion channel that said mixed medicine passage extends the mixed medicine interface that pedestal forms the cylindrical hollow structure; At least be provided with the along the circumferential direction protruding snap ring of a row on the outer wall of said mixed medicine interface, be provided with one in the mixed medicine interface and be used to seal the barrier film that mixes the medicine passage.
As a kind of preferred version of this utility model, the outer wall of said mixed medicine interface is provided with the along the circumferential direction protruding snap ring of two rows.
As the another kind of preferred version of this utility model, said barrier film is provided with an impression on its line of symmetry.
As a kind of improvement project of this utility model, be laid with the welding lines of loop configuration on the outer wall of said pedestal.
As the further improvement project of this utility model, the projection of said pedestal on its cross section is the ship shape structure, and stretches out at the two ends of the pedestal of this ship shape structure and to form the thickness thin slice of attenuation gradually.
Further again improvement project as this utility model is with on the outer wall of said mixed medicine interface and intercepts cover.
The beneficial effect of this utility model is: when using the hard double nip of this plug-in; With the pedestal seam on transfusion flexible bag; In the bottom with the needle cylindrical unit that mixes medicine interface insertion medicine mixing mouth; When mixing snap ring on the medicine interface and being stuck in intravital next the row's draw-in groove of syringe, medicine mixing mouth is fixed on and mixes on the medicine interface; When mixing medicine; Medicament reservoir is snapped in the medicine mixing mouth; Promote downwards medicine mixing mouth, mix snap ring on the medicine interface and be stuck in that syringe is intravital to be gone up in row's draw-in groove, the port that mixes the medicine interface compresses the intravital ring sealing plug of syringe; The barrier film that mixes in the medicine interface is exposed in the bottom of dosing pin, and the medicament reservoir in the medicine mixing mouth is communicated with transfusion flexible bag is interior; The hard double nip of this plug-in in use need not to adopt hose connection and foldable handle, has both reduced flexible pipe station is installed, and has avoided the weld seam leakage that brought because of the flexible pipe weld defect again, the hard double nip one-shot forming of this plug-in simultaneously, and the scope of application is wider.
