The air-locked liquid medicine filtering membrane of transparent liquid 10 is fixedly installed in bucket main body.The storage chamber of buoyancy aid can store medicinal liquid, and in dropping funnel
After the medicinal liquid emptying of inner chamber, 5 times drops of dripping hole are gradually passed through, the pressure of medicinal liquid outfan 7, anti-return blood is kept.Due to drop
The aperture of fluid apertures 5 is less, and the medicinal liquid in buoyancy aid substantially needs all to drip off for 30 minutes or so, before medicinal liquid is dripped off, defeated
Certain pressure can be kept in liquid device, it is ensured that will not blood back.
When there is the stronger medicine of the stickiness such as glucose in medicinal liquid, the gas filtration film in such as ZL 201220207483.9
It is vertically-mounted, during secondary use（That is, hang second bottle）, its gas filtration film surface can adhere to substantial amounts of glucose component causes row
Gas effect is substantially reduced；This patent will be the exhaust port 14 vertically arranged, 15 water of gas filtration film of exhaust port inner end
It is flat to arrange, it can be ensured that during secondary use, the glucose component of gas filter membrane surface adhesion is less, and exhaust effect will not be made
Into impact, gas filtration film 15 is horizontally disposed effectively can be prevented on medicinal liquid trapped gas filter membrane.
Depression forms collecting tray 23 to diapire in the middle part of the buoyancy aid downwards, and the dripping hole 5 is arranged on the bottom of collecting tray 23

Side is provided with dosing port 3, and the inner and dropping funnel body lumen conducting of dosing port 3, the outer end of dosing port are detachable
End cap 2 is installed.There is certain unexpected situation when patient is in transfusion, be able to will be tackled by the dosing port 3 unexpected
The specific drugs injection dropping funnel of situation, then it is input into human body.
Embodiment 3：The present embodiment is substantially the same manner as Example 2, and its difference is that the dropping funnel main body includes pedestal
11 and body 13, in the embedded pedestal in the body lower end and liquid medicine filtering membrane 10 is pressed on pedestal；Pedestal 11 and body 13
It is welded as a whole；Several legs 21 are provided with the downside of the buoyancy aid.The design causes the structure of dropping funnel main body more succinct, together
When enable to that buoyancy aid zone of action in the dropping funnel is bigger, the design of leg causes buoyancy aid bottom not to be attached to liquid medicine filtering membrane 10
On, so that it is guaranteed that dropping liquid effect.
The storage liquid buoyancy aid concrete scheme of the present invention is as follows：A kind of storage liquid buoyancy aid for being exclusively used in dropping funnel, including the buoyancy aid 4 of tubular, float
Storage chamber 22 is provided with vivo, and at least one dripping hole 5 is provided with the diapire in the middle part of buoyancy aid.Diapire in the middle part of the buoyancy aid to
Lower recess forms collecting tray 23, and the dripping hole 5 is arranged on the diapire of collecting tray 23.The design causes the liquid in collecting tray 23
Body pressure is bigger, drips more conducively under liquid.Secondary dropping liquid sleeve 12 is installed below the bottom of the buoyancy aid, collecting tray, it is secondary
Secondary dripping hole 6 is offered on the diapire of dropping liquid sleeve 12；The diameter of the secondary dripping hole 6<The dropping liquid of groove bottom wall of confluxing
5 diameter of hole.The design causes the effect dripped under liquid more preferably, more stable.Diameter≤the 1mm of 0.5mm≤secondary dripping hole；
Dropping liquid bore dia≤the 1.5mm of 1mm≤groove bottom wall of confluxing.
