Description
Technical field
The utility model relates to a kind of infusion apparatuses more particularly to a kind of double medium filtration to stop liquid Anti-bubble multifunctional transfusion system.
Background technique
The infusion apparatus of market is varied at present, medicine of the people when being infused using infusion apparatus, especially in infusion bottle
When liquid wants defeated most, it is necessary to transfusion needle be extracted from human body, will lead to " blood back " phenomenon if not extracting, in this way to patient's body
Body has very big harm, though infusion apparatus on the market some can accomplish to be automatically stopped infusion, but permanent clinical practice card
Bright, " blood back " phenomenon can't be completely eliminated by only stopping infusion.
In addition, it is easy to produce insoluble microparticle when the compatibilities such as some traditional Chinese medicines, Fat Emulsion Injection, biological agent, it is interior
There is more impurity in portion, and infusion apparatus on the market can not filter these granule foreigns, once granule foreign enters blood of human body
In just will have a direct impact on human health.Moreover, the particulate matter after traditional Chinese medicine and liquid compatibility can block secondary filter
The infusion apparatus of type causes lower liquid difficult.
Utility model content
In order to solve the above shortcomings in the prior art, the utility model provides a kind of double medium filtrations to stop the more function of liquid Anti-bubble
It can infusion apparatus.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme: a kind of double medium filtration stops liquid gas-tight
Bubble multifunctional infusion apparatus, including perfusion tube, puncture outfit, dropping funnel, flow regulator, female Luer and transfusion needle, the dropping funnel by
Upper dropping funnel and lower dropping funnel two parts composition, wherein the upper dropping funnel upper end be equipped be connected to perfusion tube inlet tube and be set into
The exhaust port for be infused exhaust and air inlet of liquid pipe side.
The lower dropping funnel includes the dropping funnel pedestal and lower dropping funnel support base of phase clamping；The lower end of the upper dropping funnel is connected to down
On the annular slot of dropping funnel support base upper end, the inner upper end face of the lower dropping funnel support base is equipped with the thick of one layer of hot melt installation
Filter membrane, and the bottom of the lower dropping funnel support base is equipped with the up raised convex pipe of Anti-bubble, the side of the convex pipe of Anti-bubble
It opens up and a plurality of vertically arranged drainage hole is distributed with, and the top of the convex pipe of the Anti-bubble is equipped with one layer of only liquid secondary filter film,
The inside of the lower dropping funnel support base is equipped with the pipe shoulder of the corresponding only liquid secondary filter film hot melt installation.
Preferably, the side of the lower liquid pipe of the puncture outfit is equipped with an exhaust intake valve, described to be vented the interior of intake valve
Portion is equipped with backstop in the breathable waterproof membrane of entire valve port, and the port of the exhaust intake valve goes out to be equipped with valve deck.
The designing points of the utility model have at 3 points:
The first, precision filter infusion set is effectively solved to match in infusion traditional Chinese medicine, Fat Emulsion Injection, biological agent etc.
When being easy to produce the injection of insoluble microparticle when 5, it can be blocked by the insoluble microparticle of this kind of injection, lead to not normal infusion
The problem of.The coarse filtration film in lower dropping funnel is arranged in the utility model can be first by the biggish particulate matter of particle in medical fluid
Filtering, it is therefore prevented that this particulate matter enters on the only liquid secondary filter film for falling in next layer in lower dropping funnel, prevents precision
Filter membrane is blocked by insoluble microparticle.
The second, in the only liquid secondary filter film of lower dropping funnel lower part, secondary filter film has hydrophily, and film surface is dispersed with
Multiple micropores, secondary filter film contact dropping liquid, and micropore opens, and dropping liquid penetrates auto-stopping liquid layer, are infused；Secondary filter film is de-
From dropping liquid, micropore closure, isolation air passes through, and the intracorporal cavity of valve forms negative pressure, terminates infusion.So the utility model is defeated
It after the completion of liquid, can automatically stop liquid, prevent the blood return phenomenon of infusion from occurring.
Third, the utility model the side of the convex pipe of Anti-bubble open up the drainage hole of drain, liquid mode under such side
Effectively prevent the generation of infusion bubble, it is therefore prevented that bubble enters perfusion tube, guarantees infusion safety, reduces the defeated of medical worker
Exhaust work operations amount when liquid, can directly plug bottle infusion without carrying out secondary exhaust work especially when being infused continuous bottle.
Compared with prior art, the utility model can stop the medical fluid in dropping funnel to be directly entered perfusion tube, it is therefore prevented that gas
The generation of bubble, and the function that only liquid secondary filter film closes micropore at the end of being infused soon is dexterously combined, accomplish certainly
It is dynamic to stop infusion, it is therefore prevented that the generation of " blood back " phenomenon, at the same time, the drainage hole of the side feed liquor of use are accomplished well
Anti-bubble infusion, total is easily achieved, practical, is worth significantly promoting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the dropping funnel of the utility model.
Specific embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
