Spring, tension spring is sleeved on lower buoyancy valve rod, and the lower end of tension spring is fixed on lower bullet formula floating valve, with lower bullet
Formula floating valve is connected as a single entity, lower buoyancy valve seat be located at lower bullet formula floating valve upper end, lower conical gear-like bullet formula floating valve with
Tension spring and valve seat combination are into down spring buoyancy control valve, and down spring buoyancy control valve is arranged in transfusion connector, transfusion
The lower end of connector is provided with internal thread, and the bottom of connector is provided with sealing film, and the lower end of sealing film is standby provided with sealing
Scalp intravenous needle.Described elastic force filtration, purification association is used for the pressure for buffering the liquid retained in Mophi type drip, and
The attraction of liquid in lower liquid-transport pipe-line is offset, retains the stability with liquid in lower liquid-transport pipe-line in Mophi type drip, is allowed to
In transfusion bottle after liquid drop light, upper tubing can be kept, not Fei Shi drops kettle, the dynamic equilibrium of lower transfusion liquid.Pass through reality
Test observation, during transfusion, under the flow rate of liquid of 60 drops/minute, after liquid is dripped off in transfusion bottle, can also keep drop kettle in and
Liquid in lower woven hose is retained more than 20 minutes, so as to after being dripped off to liquid in transfusion bottle, win and safely change next bottle
The time of liquid.In use, opening sealing film, it is installed in transfusion device connector the inner with threaded connection by scalp intravenous needle
It can infuse.
During transfusion, the puncture needle of transfusion device upper end is inserted in transfusion bottle, the decoction in transfusion bottle is along upper tubing

The liquid of upper end is extruded down into space in elastic force filtration, purification association in family name's drop kettle, make floating valve inlet opening and drop keyholed back plate it
Between have appropriate liquid, and space is left in the upper end of liquid, to observe in the drop speed of liquid, drop kettle after the completion of liquid adjustment i.e.
Transfusion can be started, liquid is in the presence of atmospheric pressure and liquid head pressure, and the gear-like elastic valve for washing lower end in drop kettle open will
Tension spring compress, after being purified through strainer filtering downwards, then wash open after the fluid hole of elastic rubber film enter lower woven hose in,
The liquid flowed downwardly into washes the lower bevel gear shape bullet formula floating valve in transfusion connector open again, along scalp vein needle tract stream
Enter in the vein blood vessel of patient, when the decoction in transfusion bottle drips light, the bevel gear shape elastic valve in drop kettle is in tension force
Under the elastic force effect of spring, inlet opening is blocked upwards, liquid-transport pipe-line is closed, while the elastic force in upper, middle and lower cross structure
Rubber film also shrinks the fluid hole in film, the liquid in drop kettle and in lower liquid-transport pipe-line is slowed down the speed flowed downward
And reduce pressure.Now, drawing of the plane in tension spring on the lower bevel gear shape bullet formula floating valve in transfusion connector
Under power effect, floated closure transfusion fluid hole, and fluid hole is closed, prevents blood from being backflowed to woven hose, then can be safe
Etc. next bottle liquid medicine to be replaced continue to infuse.Plane is combined with fluid hole on described lower bevel gear shape elastic force floating valve
Into new fluid control device, during transfusion, decoction flows out the space through floating valve upper end by fluid hole and flowed out, you can ensure defeated
Liquid it is unobstructed, and can anti-Hemostatic Oral Liquid backflow.
