Description
Technical field
The present invention relates to the infusion set of medical industry, a kind of achievable many bottles of soft bottles, many bottles of hard bottles or many are referred in particular to
Automatic decanting is automatic after liquid transfusion head after the universal medical infusion of liquid when the soft or hard bottle mixing of bottle is infused.
Background technology
In medical industry, continuous transfusion is not also common, and traditional single bottle is infused, manually changes bottle, is brought to medical worker
Great labour intensity, also easily because casual carelessness causes some malpractices.In order to solve the above problems, realize continuous
Transfusion automatic decanting purpose, present inventor have developed and be capable of achieving the automatic several generations product after liquid.
Patent of invention ZL2012104089744《It is a kind of automatically control liquid, the double passage transfusion that gas timesharing is mutually input into
Head》, although the design of two passages and ball float control are employed, but the program cannot be used for the transfusion of soft bag container, because of soft bag container
Air inlet is not needed, as long as connection begins to transfusion.If this is designed for soft bag liquid all liq bottle can be caused simultaneously defeated
Liquid, further results in all liq mixing, triggers security incident.In addition, one bottle of inlet end also can be because of law of connected vessels at first
And causing liquid to backflow causes excessive, initiation waste.And the float valve design of the program causes the strength closed too
Few, far from the pressure of liquid in the soft bottle of facedown, therefore float valve structure needs to improve.
Present inventor also specially devises automatic decanting device, application number 2014107308437 for the transfusion of soft bottle
It is disclosed《It is a kind of for soft bag infusion it is automatic after liquid infuse head》, using improved float valve（It is ingenious to be counteracted that soft bottle
The huge fluid pressure of liquid）Transfusion to realize current soft bottle is waited, when previous bottle input air beats ball float sinking valve
Releasing transfusion of coming is waited, and realizes the automatic decanting of soft bottle transfusion.But this theory structure can not infuse suitable for hard bottle simultaneously
Automatic decanting demand.
In order to meet general requirement, present inventor is improved again, patent application 201410730840.3
《It is a kind of universal automatic after liquid transfusion head》A kind of transfusion header structure for being applicable to soft, hard infusion vessel is disclosed, is attempted whole
Close two kinds of principles of physical control automatic decanting, that is, control hard bottle liquid in due course air inlet come realize the transfusion of hard bottle from
Move bottle, and allow soft bag container below to realize that transfusion is waited, and termination in good time waits realizing moving certainly for soft bottle transfusion
Bottle both automatic decanting principles.Certainly soft bottle will also prevent liquid from backflowing when infusing.But found in reality processing and use
This universal design there is also some problems.Such as：Using Liao Liangge valve boxs and the structure of two valves, system is increased
Difficulty of processing is made, processing efficiency is reduced, and the smaller buoyancy of ball float is not enough.The valve opening and closing of Liang Ge valve boxs can not be accomplished together
Step, causes the air when hard bottle is infused to come near the valve box of feed tube but do not opened near the valve of drain pipe（Not yet
There is air to enter）, all closing causes transfusion to suspend at this moment all openings for connecting drain pipes.Even if after solving valve synchronization
（Such as in ball float bottom rigid connection, the movement slots of rigid connection bar are opened in valve interventricular septum）When can not realize that hard bottle is infused
After two valves are opened simultaneously, continuous transfusion is effectively realized.Because such synchronous valve design can cause to enter previous
Air in valve box can enter in latter valve box through the movement slots of valve interventricular septum bottom, and produce two consequences, and one is
Drain pipe may be directly entered into the gas in latter valve box, gas can be caused to enter in human body；Even if two is gas
Do not flow into drain pipe and flow to the pipeline tapping on valve box top, this can also influence liquid in the bottle of the opening to flow out, because preceding
The air pressure of latter two valve box's top end opening is equal, and liquid does not flow out.
In sum, prior-generation product cannot be used for soft bag infusion, be only used for hard bottle transfusion, and in actual use
Also bleeding trouble, sealing is covered when transfusion head is in no insertion infusion bottle with transfusion head protection（Not so gas warp is had
The opening at transfusion crown end enters drain pipe）Etc. defect.And the design for being applied to soft bottle automatic decanting can not be while be used for hard
The automatic decanting of bottle transfusion.The universal product of next generation has breakthrough in terms of hard bottle, soft bottle automatic decanting principle is integrated, but
Defect is also more apparent, and minor modifications are carried out on the basis of original（As rigid connection makes valve synchronization）Can not thoroughly solve to ask
Topic.Therefore the next generation original combination thoughts of universal product, the emphasis solution on the basis of float valve physical control are broken
Certainly two problems, one is valve stationary problem, and two is that the fluid passage that another side is opened when one side inlet channel is opened will be led
The dynamic pumping liquid from bottle, makes air be additionally related to multi-functional passive entry in bottle（Because gas actively will not cause into such being certain in bottle
Transfusion stops）.
The content of the invention
The purpose of the present invention is directed to shortcoming present in background technology and problem is improved and innovated, and reintegrates
