Abstract
The invention discloses a plug-in type dual-valve cover, wherein a dual-valve cover body is provided with a chemicals mixing channel and a transfusion channel; the chemicals mixing channel extends out of the dual-valve cover body to form a chemicals mixing port; an annular lug boss is saliently arranged on the external wall of the chemicals mixing port and provided with an external thread; a clamp ring is arranged on the external wall of an end port of the chemicals mixing port, and a diaphragm is arranged inside the chemicals mixing port; and the external diameter of the clamp ring is not more than the external diameter of the annular lug boss. When the plug-in type dual-valve cover is in use, the dual-valve cover body is welded on a port of a transfusion container, the bottom of a syringe is sleeved on the chemicals mixing port, the clamp ring is located on a locating ring and the syringe and the chemicals mixing port are fixed; during the mixing of the chemicals, a chemicals container is inserted into a chemicals mixing nozzle and rotated downward, so that the diaphragm is punctured by the bottom of a chemicals feeding syringe and the chemicals container is communicated with the inside of the transfusion container; a hose for connection and an easily folded handle are not needed during the use of the cover, so that not only the mounting location for the hose is reduced, but also the liquid leakage of a welded seam, caused by the welding defect of the hose, is avoided; meanwhile, the plug-in type dual-valve cover is molded at a time and has wider scope of application.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of bivalve lid 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 infusion vessel, and the interior medicinal liquid of infusion vessel injects or output is usually covered realization through bivalve.
In the prior art, the bivalve lid comprises that bivalve lid, the top of bivalve lid are provided with one and mix a medicine passage and an infusion channel, and the bottom of bivalve lid is the connectivity port.Mix the medicine passage and extend the mixed medicine interface that the bivalve lid forms the cylindrical hollow structure, infusion channel is extended the transfusion interface that the bivalve lid forms the cylindrical hollow structure.
The in use main deficiency as follows that exists of the bivalve lid of said structure: 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, the bivalve lid 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 bivalve of said structure lid when being connected with medicine mixing mouth through flexible pipe, also need be installed foldable handle in the flexible pipe.
Summary of the invention
To the above-mentioned deficiency that exists 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 of welding produces, reduce station is installed, and one-time formed plug-in type bivalve lid.
In order to solve the problems of the technologies described above; The present invention has adopted following technical scheme: plug-in type bivalve lid; Comprise the bivalve lid, the top of said bivalve lid is provided with one and mixes a medicine passage and an infusion channel, and said mixed medicine passage extends the mixed medicine interface that the bivalve lid forms the cylindrical hollow structure; An along the circumferential direction outside protruding annular boss is provided with external screw thread on the outer wall of said mixed medicine interface on this annular boss, and the port outer wall that mixes the medicine interface is provided with the snap ring of a loop configuration, is provided with one in the mixed medicine interface and is used to seal the barrier film that mixes the medicine passage; The external diameter of said snap ring is not more than the external diameter of annular boss.
As a kind of preferred version of the present invention, said annular boss is located on the middle part excircle of said mixed medicine interface.
As another kind of preferred version of the present invention, said barrier film is provided with an impression on its line of symmetry.
As a kind of improvement project of the present invention, be with on the said annular boss and intercept cover.
The invention has the beneficial effects as follows: when using this plug-in type bivalve lid; With the seam of bivalve lid on the interface of infusion vessel; The bottom of the needle cylindrical unit of medicine mixing mouth is enclosed within mixes on the medicine interface, the snap ring that mixes on the medicine interface is positioned on the locating ring of needle cylindrical unit, needle cylindrical unit is fixed on mixes on the medicine interface; When mixing medicine, medicament reservoir is inserted medicine mixing mouth and is rotated down, make the bottom of dosing pin expose the barrier film that mixes in the medicine interface, the medicament reservoir in the medicine mixing mouth is communicated with infusion vessel is interior; This plug-in type bivalve lid 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, this plug-in type bivalve lid one-shot forming simultaneously, and the scope of application is wider.
