Description
Technical field:
Stop liquid precision filter infusion set the present invention relates to a kind of disposable automatic exhaust.
Background technology:
At present, fluid transport therapy is a kind of clinical the most frequently used treatment method, and although the common disposable transfusion device of tradition solves
The problem mutually infected between patient, but still there are some defects, first, because common disposable transfusion device is without automatic
Closing function, therefore when infusion bottle is exchanged or injecting liquid drug is completed, easily admit air into human body, gently then give medical personnel
Bring many unnecessary troubles, it is heavy then cause great malpractice；Second, the mistake that common disposable filtering transfusion device is used
Filter membrane fenestra aperture is in more than 10um, and the blood vessel pore of human body is 7-9um, easily causes human vas capillary blockage,
Phlebitis is produced, occurs infusion reaction during transfusion；There is precision filter infusion set miscellaneous on the market, on patent document in front
Above-mentioned difficulties are solved；The filter membrane that the filter membrane of accurate filter is used at present is 5um or below 5um for fenestra aperture
Hydrophilic nanoporous filter membrane, will not be produced less than human vein pore, during transfusion infusion reaction and can preferably prevent phlebitis；
Patent document and precision transfusion filter its filter on the market be typically all below the dropping funnel of transfusion device in front, filtering
Device and dropping funnel maintain a certain distance, need to be exhausted this segment distance during exhaust, therefore, the feed liquor of current filter
One piece of hydrophobic membrane is designed with the lid in storehouse for being vented, filter is a good accurate mistake with the distance height of intravenous needle
The basis of filter, the micropore filtering film of accurate filter due to there was only 5um or below 5um in aperture, with only liquid function, one bottle of medicine
When liquid transfusion is completed, whereabouts liquid is entered to film location, liquid no longer flows down, air will not enter human body, and patient will not produce probably
Flurried psychology, the only liquid height of a good precision filter infusion set should reach 1.6 meters or more, in front accurate mistake on the market
Filter infusion apparatus only liquid height from 30cm to 1,60 meters.
The content of the invention:
Stop liquid precision filter infusion set it is an object of the invention to provide a kind of disposably automatic exhaust, when transfusion device starts to infuse certainly
Dynamic exhaust, transfusion device is totally lost after liquid can be in film location with automatic liquid-stopping, and air can not enter human body and anti-Hemostatic Oral Liquid flows back.
The present invention is adopted the following technical scheme that and realizes its goal of the invention：It is defeated that a kind of single use secondary filter stops liquid
Liquid device, it is defeated by bottle plug puncture unit 1, feed tube 2, secondary filter dropping funnel 3, drain pipe 4, flow regulator 5, female Luer 6, vein
Liquid pin 7 is constituted, and air inlet pipe 1-1 is provided with bottle plug puncture unit 1；Bottle plug puncture unit 1 passes through feed tube 2, secondary filter dropping funnel
3rd, drain pipe 4, flow regulator 5, female Luer 6 are connected with intravenous infusion needle 7；Secondary filter dropping funnel 3 is by dropping funnel 3-1, feed liquor
Blast pipe 3-2, accurate filter 3-3 are constituted, and filter base 3-3-2 is provided with dropping funnel bottom 3-3-6；The dropping funnel 3-1 peaces
On the 3-3-6 of dropping funnel bottom, feed liquor blast pipe 3-2 is arranged in the 3-3-6 of dropping funnel bottom, is provided with feed liquor blast pipe 3-2
Feed liquor air discharge duct 3-2-1 and feed liquor steam vent 3-2-2.
In order to realize automatic ventilating function, the dropping funnel wall 3-1-2 of dropping funnel 3-1 is provided with exhaust outlet 3-1-3 to the present invention；It is described
The exhaust membrane of exhaust outlet 3-1-3 is microporous hydrophobic membrane 3-1-5；The microporous hydrophobic membrane 3-1-5 is carried out close by seal 3-1-4
Envelope.
Be designed to accurate filter 3-3 by strainer cover 3-3-1, precision in order to realize secondary filter function by the present invention
Filter membrane 3-3-4, filter base 3-3-2 constitute, wherein accurate filter 3-3 with secondary filter film 3-3-4 as cut-off rule,
Two of secondary filter film 3-3-4 are respectively equipped with feed liquor storehouse 3-3-3 and go out liquid storehouse 3-3-5.
The present invention in order to realize for the air in the feed liquor storehouse of filter being vented back to dropping funnel, by the face of feed liquor air discharge duct 3-2-1
Area of the product less than feed liquor steam vent 3-2-2, or the width of feed liquor air discharge duct 3-2-1 is straight less than feed liquor steam vent 3-2-2
Footpath；The feed liquor air discharge duct 3-2-1 can be designed to a plurality of；By feed liquor storehouse 3-3-3 and the dropping funnel liquid outlet tight phases of 3-3-6-1
It is logical.
The present invention in order to realize that the liquid by filter is flowed down along wall, by feed liquor storehouse 3-3-3 be designed to a slope, under
Upward area progressively expands.
Working method of the invention is：Flow regulator 5 is closed, bottle plug puncture unit 1 is inserted into bottle stopper, liquid from feed tube
2 enter secondary filter dropping funnel 3, and exhaust outlet 3-1-3 passes through feed liquor air discharge duct 3-2- to being vented, being vented liquid simultaneously outside dropping funnel automatically
1 limit flow enters feed liquor steam vent 3-2-2, and liquid reaches feed liquor storehouse 3-3-3, and liquid liquid level goes up, and feed liquor storehouse 3-3-3 is by liquid
In the air return for squeezing out to dropping funnel, through exhaust outlet 3-1-3 to being vented automatically outside dropping funnel, liquid automatic tensioning to exhaust outlet 3-1-
Turn-on flow rate adjuster 5 during 3 highest exhaust position, liquid enters liquid storehouse 3-3-5 through secondary filter film 3-3-4, through going out
Liquid pipe 4 is flowed out to intravenous infusion needle 7, and capillarity, Ke Yitong are once produced because the aperture of drain pipe 4 is generally 3mm or 3mm
When discharge drain pipe 4 in air, when the liquid in medicinal liquid bottle is dripped off, auto-stopping when liquid liquid level drops to filter bottom
Liquid, liquid no longer declines, and air will not enter human vas.
As a result of above technical scheme, the present invention preferably realizes its goal of the invention, through many experiments, the present invention
Only liquid height more than 1.6 meters, feed liquor storehouse and dropping funnel liquid outlet are closely communicated design under, feed liquor air discharge duct control liquid
Preferably can be vented back to the air in feed liquor storehouse in dropping funnel by the feed liquor storehouse of filter in the presence of body flow, will not be accumulated in feed liquor storehouse
Pressure air；Then spacing exhaust can preferably be realized by exhaust apparatus on dropping funnel wall and is vented automatically under liquid gravity pressure
To outside dropping funnel；Secondary filter film can be not only prevented in feed liquor storehouse the liquid slag of more than 5um, prevent phlebitis, it is to avoid go out
Existing infusion method, effectively whereabouts liquid can also be entered when transfusion is completed using filter membrane, and air will not intravasation, it is to avoid produce doctor
The generation for the treatment of accident.
