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.
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 one-time formed bivalve lid.
In order to solve the problems of the technologies described above; This utility model has adopted following technical scheme: the 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 this utility model, said annular boss is located on the middle part excircle of said mixed medicine interface.
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 with on the said annular boss and intercept cover.
The beneficial effect of this utility model is: when using this 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 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 bivalve lid one-shot forming simultaneously, and the scope of application is wider.
