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 with medicine mixing mouth and soft transfusion bottle thereof.
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 soft transfusion bottle, and the medicinal liquid in the soft transfusion bottle injects or output usually by the dual-valve cover realization with medicine mixing mouth.
In the prior art, mainly contain with the dual-valve cover of medicine mixing mouth and to comprise bivalve lid, mixed medicine card, needle cylindrical unit, flexible pipe, foldable handle and medicine feeding needle.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.Mixed medicine card is the cylindrical hollow structure, and medicine feeding needle is located in the mixed medicine card, the lower surface of mixed medicine card and the sealing of medicine feeding needle outer wall, and needle cylindrical unit is positioned at the lower surface of mixed medicine card.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, and with this needle cylindrical unit seam.Foldable handle is installed in the flexible pipe, and is mainly that the passage between medicine feeding needle and the mixed medicine interface is stifled disconnected, during mixed medicine, needs foldable handle is fractureed, could be with the channel connection between medicine feeding needle and the mixed medicine interface.
In use mainly there is following deficiency in the dual-valve cover with medicine mixing mouth of said structure: when one, needle cylindrical unit is connected with mixed medicine interface, 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, 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, mixed medicine interface 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 with medicine mixing mouth of said structure when mixed medicine interface is 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 dual-valve cover with medicine mixing mouth.
Simultaneously, the present invention also provides a kind of in use need not to adopt foldable handle and flexible pipe, avoids reducing the soft transfusion bottle that station is installed because welding produces mixed medicine leakage.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: with the dual-valve cover of medicine mixing mouth, comprise bivalve lid, mixed medicine card, needle cylindrical unit and medicine feeding needle; 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; Described medicine feeding needle is located in the mixed medicine card, and needle cylindrical unit is positioned at the lower surface of mixed medicine card;
A protruding annular boss along the circumferential direction 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 bottom of described medicine feeding needle forms the sealing-plug installation cavity of annular to downward-extension and with the inwall of needle cylindrical unit, is provided with ring sealing plug in the described sealing-plug installation cavity; 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;
Described needle cylindrical unit is enclosed within on the mixed medicine interface, and snap ring is positioned at the top of locating ring; After being rotated down mixed medicine card, the port compression ring sealing plug of mixed medicine interface, barrier film is passed in the bottom of needle cylindrical unit.
As a preferred embodiment of the present invention, described barrier film is provided with an impression at its line of symmetry.
As another kind of preferred version of the present invention, described mixed medicine card is the cylindrical hollow structure, is symmetrically arranged with at least two at the inwall that mixes the medicine card and is used for preventing fixture block that medicament reservoir withdraws from and that be obliquely installed.
As a kind of improvement project of the present invention, the elongated end of medicine feeding needle bottom has an arcuate structure to lower convexity.
As another kind of improvement project of the present invention, be provided with seal cover in the upper end of mixed medicine card.
Scheme is overlapped on the described annular boss to have to intercept and is overlapped as a further improvement on the present invention.
Soft transfusion bottle provided by the invention comprises soft transfusion bottle bottle and the above-mentioned dual-valve cover with medicine mixing mouth, and the bottom seam of this bivalve lid is on the bottleneck of this soft transfusion bottle bottle.
The invention has the beneficial effects as follows: when using this with the dual-valve cover of medicine mixing mouth and soft transfusion bottle thereof, with the connectivity port seam of bivalve lid bottom on the bottleneck of soft transfusion bottle bottle, needle cylindrical unit is enclosed within on the mixed medicine interface, snap ring on the mixed medicine interface is positioned on the locating ring of needle cylindrical unit, the port of mixed medicine interface is pressed in ring packing beyond the Great Wall, and needle cylindrical unit is fixed on the mixed medicine interface; When mixing medicine, medicament reservoir is inserted in the mixed medicine card, be rotated down medicine mixing mouth, make the port compression ring sealing plug of mixed medicine interface, barrier film is passed in the bottom of needle cylindrical unit, and the medicament reservoir in the medicine mixing mouth is communicated with the soft transfusion bottle bottle is interior; This with the dual-valve cover of medicine mixing mouth and soft transfusion bottle thereof in use, need not to adopt hose connection and foldable handle, both reduced flexible pipe station had been installed, avoided again the weld seam leakage that brings because of the flexible pipe weld defect, and this dual-valve cover and soft transfusion bottle scope of application thereof with medicine mixing mouth had been wider.
