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 dual-valve cover that is connected with infusion vessel.
Background technology
In clinical treating disease, often give patient infusion or by intravenous drip directly with in the infusion of medicine body, medicine often is stored in the infusion vessel, and the medicinal liquid in the infusion vessel injects or export and usually realize by dual-valve cover.
In the prior art, dual-valve cover comprises the bivalve lid, and the top of bivalve lid is provided with mixed medicine passage and an infusion channel, and the bottom of bivalve lid is the connectivity port.Mixed medicine passage extends the mixed medicine interface that the dual-valve cover body forms the cylindrical hollow structure, and infusion channel is extended the infusion connector that the dual-valve cover body forms the cylindrical hollow structure.
In use mainly there is following deficiency in the dual-valve cover of said structure: one, when being connected with medicine mixing mouth, need by hose connection, one end of flexible pipe is enclosed within on the mixed 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 again the welding position, increased the probability because of welding position leakage when mixing medicine; Two, dual-valve cover is connected with medicine mixing mouth by flexible pipe, because of the restriction of material that flexible pipe adopts, in temperature lower (such as zubzero temperature), easily causes the welding position cracking of flexible pipe, and then causes mixed medicine leakage; Three, the dual-valve cover of said structure when being connected with medicine mixing mouth by flexible pipe, also need be installed foldable handle in the flexible pipe.
Summary of the invention
For above shortcomings in the prior art, the invention provides a kind of in use need not and adopt foldable handle and flexible pipe, avoid reducing station being installed because welding produces mixed medicine leakage, and one-time formed plug-in type dual-valve cover.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: plug-in type dual-valve cover, comprise the bivalve lid, the top of described bivalve lid is provided with mixed medicine passage and an infusion channel, and described mixed medicine passage extends the mixed medicine interface that the dual-valve cover body forms the cylindrical hollow structure; An outside protruding annular boss in the circumferential direction of the circle on the outer wall of described mixed medicine interface is provided with external screw thread at this annular boss, and the port outer wall of mixed medicine interface is provided with the snap ring of a loop configuration, is provided with a barrier film that is used for the sealed mixed medicine passage in the mixed medicine interface; The external diameter of described snap ring is not more than the external diameter of annular boss.
As a preferred embodiment of the present invention, described annular boss is located on the middle part excircle of described mixed medicine interface.
As another kind of preferred version of the present invention, described barrier film is provided with an impression at its line of symmetry.
As a kind of improvement project of the present invention, cover has the cover of obstruct on the described annular boss.
The invention has the beneficial effects as follows: when using this plug-in type dual-valve cover, 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 on the mixed medicine interface, and the snap ring on the mixed medicine interface is positioned on the locating ring of needle cylindrical unit, and needle cylindrical unit is fixed on the mixed medicine interface; During mixed medicine, medicament reservoir is inserted medicine mixing mouth and be rotated down, make the bottom of medicine feeding needle expose barrier film in the mixed medicine interface, the medicament reservoir in the medicine mixing mouth is communicated with infusion vessel is interior; This plug-in type dual-valve cover in use need not to adopt hose connection and foldable handle, has both reduced flexible pipe station is installed, and has avoided again the weld seam leakage that brings because of the flexible pipe weld defect, simultaneously this plug-in type dual-valve cover one-shot forming, and the scope of application is wider.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the front view of plug-in type dual-valve cover, and Fig. 2 is the structural representation of mixed medicine interface, as shown in the figure.Plug-in type dual-valve cover comprises bivalve lid 1, and the top of bivalve lid 1 is provided with mixed medicine passage 2 and an infusion channel 3, and the bottom of bivalve lid 1 is the connectivity port.Mixed medicine passage 2 extends the mixed medicine interface 21 that bivalve lid 1 forms the cylindrical hollow structure, and infusion channel 3 extends outward the infusion connector that bivalve lid 1 forms the cylindrical hollow structure.An outside protruding annular boss 4 in the circumferential direction of the circle on the outer wall of mixed medicine interface 21 is provided with external screw thread (in the present embodiment, annular boss 4 is located on the middle part excircle of mixed medicine interface 21) at this annular boss 4.The port outer wall of mixed medicine interface 21 is provided with the snap ring 5 of a loop configuration, the mixed medicine interface 21 interior barrier films 6 for sealed mixed medicine passage 2 that are provided with.The external diameter of snap ring 5 is not more than the external diameter of annular boss 4.
