Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to the plug-in type medicine mixing mouth that hard double nip a kind of and on the infusion vessel is connected.
Background technology
In clinical treating disease, often directly medicine is injected in the body to patient infusion or by intravenous drip, medicine often is stored in the transfusion bag, and the medicinal liquid in the transfusion bag injects or output usually realizes by medicine mixing mouth.
In the prior art, medicine mixing mouth comprises mixed medicine card body, needle cylindrical unit and dosing pin.Mixing medicine card body is the cylindrical hollow structure, and the dosing pin is located at and mixes in the medicine card body, and the needle point of dosing pin upwards mixes lower surface and the sealing of dosing pin outer wall of medicine card body, and needle cylindrical unit is positioned at the lower surface of mixing medicine card body.
In use mainly there is following deficiency in the medicine mixing mouth of said structure: one, when hard double nip on the infusion vessel is connected, need by hose connection, one end of flexible pipe is enclosed within on the mixed medicine interface on the hard double nip, and with this mixed medicine interface seam, the other end of flexible pipe is enclosed within on the needle cylindrical unit, and with this needle cylindrical unit seam, so both increased the installation station of flexible pipe, increase the welding position again, increased the probability because of welding position leakage when mixing medicine; Two, medicine mixing mouth is connected with mixed medicine interface on the hard double nip by flexible pipe, because of the restriction of material that flexible pipe adopts, in temperature lower (as zubzero temperature), easily causes the welding position of flexible pipe to ftracture, and then causes mixed medicine leakage; Three, the medicine mixing mouth of said structure when mixed medicine interface on the hard double nip is connected, also need be installed foldable handle in the flexible pipe by flexible pipe.
Summary of the invention
At above shortcomings in the prior art, the invention provides a kind of in use need not and adopt foldable handle and flexible pipe, avoid mixing the medicine leakage because welding produces, reduce station is installed, and one-time formed plug-in type medicine mixing mouth.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: the plug-in type medicine mixing mouth comprises and mixes medicine card body, needle cylindrical unit and dosing pin; Described mixed medicine card body is the cylindrical hollow structure, and described dosing pin is located at and mixes in the medicine card body, mixes lower surface and the sealing of dosing pin outer wall of medicine card body, and described needle cylindrical unit is positioned at the lower surface of mixing medicine card body; The bottom of described dosing pin is extended downwards and is formed the sealing-plug installation cavity of annular with the inwall of needle cylindrical unit; The inwall of described needle cylindrical unit along the circumferential direction is provided with locating ring, and the bottom interior wall of needle cylindrical unit is provided with female thread, and described locating ring is between sealing-plug installation cavity and female thread, and the internal diameter of locating ring is not more than the internal diameter of female thread.
As a preferred embodiment of the present invention, be provided with sealing-plug in the described sealing-plug installation cavity.
As another kind of preferred version of the present invention, be symmetrically arranged with at least two at the inwall that mixes medicine card body and be used for preventing medicament reservoir lid fixture block that withdraw from and that be obliquely installed.
As another preferred version of the present invention, the elongated end of dosing pin bottom has an arcuate structure that protrudes downwards.
Scheme is provided with seal cover in the upper end of mixing medicine card body as a further improvement on the present invention.
The invention has the beneficial effects as follows: when using this plug-in type medicine mixing mouth, the bottom of needle cylindrical unit is enclosed within mixes on the medicine interface, promote to mix medicine card body downwards, the snap ring that mixes on the medicine interface is positioned on the locating ring of needle cylindrical unit, and medicine mixing mouth and mixed medicine interface are fixed; When mixing medicine, medicament reservoir is inserted in the mixed medicine card body, be rotated down mixed medicine card body, make the bottom of dosing pin expose the barrier film that mixes in the medicine interface, mix the interior medicament reservoir of medicine card body and be communicated with transfusion flexible bag is interior; This plug-in type medicine mixing mouth 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 brings because of the flexible pipe weld defect again, this plug-in type medicine mixing mouth one-shot forming simultaneously, and the scope of application is wider.
