For making the purpose of this utility model, technical scheme and advantage clearer, new below in conjunction with this practicality
The accompanying drawing of type, provides the description of specific embodiment, but not as to any restriction of the present utility model.
See Fig. 1～Fig. 3, a kind of transfusion device, it is characterised in that: include intravenous needle 1, bottle plug puncture unit 2,
Drip kettle 3 and fluid stopping device 4；Bottle plug puncture unit 2, a kettle 3 and intravenous needle 1 are connected successively by infusion tube 5
Connect, in dripping kettle 3, be fixed with ring shaped retainer member 6；Fluid stopping device 4 is arranged on and drips in kettle 3, and fluid stopping device 4
Between keeper 31 and the inlet or the liquid outlet that drip kettle 3.
Further, ring shaped retainer member 6 is horizontally placed on the top dripping kettle 3, the outside of ring shaped retainer member 6
It is connected with the inwall dripping kettle 3.
Further, fluid stopping device 4 includes chock plug 41 and cock body 42, and cock body 42 is positioned at ring shaped retainer member 6
Bottom, one end of cock body 42 is connected with one end of chock plug 41, the other end of chock plug 41 with drip the going out of kettle 3
Liquid mouth coordinates.Chock plug 41 is cylinder, and the other end of chock plug 41 is hemispherical, the diameter of chock plug 41 with drip
The diameter of the liquid outlet of kettle 3 matches.Cock body 42 is cylinder, and the diameter of cock body 42 is interior with a kettle 3
Footpath matches；The outer wall of cock body 42 is provided with multiple sump pit 421, and the width of ring shaped retainer member 6 is less than institute
The degree of depth of some sump pits 421.The density of the density≤medicinal liquid of the material of fluid stopping device 4.
Further, drip a kettle 3 and include first kettle 31 and second kettle 32, one end of infusion tube 5 with
First kettle 31 is connected, and the other end of infusion tube 5 passes flow regulator 7 and the one of second kettle 32
End connects, and the other end of second kettle 32 is connected with intravenous needle 1 by infusion tube 5.
Further, fluid stopping device 4 includes the first fluid stopping device 43 and the second fluid stopping device 44, and first only
Stream device 43 is arranged in first kettle 31, and the second fluid stopping device 44 is arranged in second kettle 32；
The fluid stopping part 42 of the first fluid stopping device 43 coordinates with the liquid outlet of first kettle 31, the second fluid stopping device
The fluid stopping part 42 of 44 coordinates with the inlet of second kettle 32.
Further, also include that liquid medicine filter 8, liquid medicine filter 8 are arranged on connection and drip kettle 3 and vein
On the infusion tube 5 of pin 1；Multiple steam vent 81 it is provided with on liquid medicine filter 8.
Further, also include that alarm device 9, alarm device 9 are arranged on connection bottle plug puncture unit 2 and drip
On the infusion tube 5 of kettle 3；Alarm device 9 includes flow transducer 91 and alarm 92, flow sensing
Device 91 is arranged on and connects bottle plug puncture unit 2 and drip on the infusion tube 5 of kettle 3, flows through transfusion for monitoring soft
The medicinal liquid flow of pipe 5；Alarm 92 is connected with flow transducer 91, is used for receiving flow transducer 91 and supervises
The medicinal liquid flow of the drainage tube measured, and send alarm command when medicinal liquid flow is zero.
The technical solution of the utility model is achieved in that
During use, bottle plug puncture unit 2 is inserted infusion bottle 10, it is not necessary to be inverted or extrude dropping funnel, being also not required to
Flow regulator 7 to cut out, medicinal liquid can be flowed into by infusion tube 5 and drip in kettle 3；In first kettle 31,
Due to the density of density≤medicinal liquid of the material of fluid stopping device 4, along with the medicinal liquid in first kettle 31 is slowly gone up
Rising, the buoyancy that the first fluid stopping device 43 is subject to is more than the gravity of the first fluid stopping device 43 self, at buoyancy
Under effect, till the first fluid stopping device 43 is also slowly increased to contact with keeper 6, now, medicinal liquid along
The sump pit 421 arranged on cock body 42 outer wall flows downward；The liquid flowed out from first kettle 31 passes through defeated
Liquid flexible pipe 5 flows through liquid medicine filter 8, and the steam vent 81 that liquid medicine filter 8 is arranged will enter first kettle
Gas in gas-liquid mixture in 31 is discharged, and intercepts bubble in small, broken bits, can make first kettle 31 simultaneously
The liquid level that interior holding is certain, thus realize repeatedly aerofluxus automatically；The liquid flowed out from liquid medicine filter 6
Flowing in second kettle 32 by infusion tube 5, under the effect of the downward active force of medicinal liquid, second only
The cock body of stream device 44 contacts with keeper 6, the sump pit 421 that medicinal liquid is arranged on cock body 42 outer wall
Flow downward, infused by intravenous needle 1.
When blood or medicinal liquid occur to flow backwards, the vein pressure that the second fluid stopping device 44 is subject to is more than second only
The downward active force that stream device 44 is subject to, therefore, the second fluid stopping device 44 under the effect of vein pressure
Move to the inlet of second kettle 32, when the chock plug 41 of the second fluid stopping device 44 inserts second kettle 32
Inlet in time, effectively prevent blood or medicinal liquid and flow backwards, it is to avoid the generation of malpractice.
When the medicinal liquid in first kettle 31 is gradually reduced, the first fluid stopping device 43 is gradually reduced along with medicinal liquid,
Until the chock plug 41 of the first fluid stopping device 43 inserts in the liquid outlet of first kettle 31, in infusion tube 5
Medicinal liquid do not continues to flow downward, and effectively prevent air and enters in the patient, it is to avoid sending out of malpractice
Raw.Meanwhile, it is also possible to stop the flowing of medicinal liquid by closing flow regulator.
Between infusion bottle and bottle plug puncture unit 2 and first kettle 31, the medicinal liquid in infusion tube 5 flows to end
Time, the medicinal liquid flow that flow transducer 91 monitors is zero, has now also retained a small amount of in first kettle 31
Medicinal liquid can continue transfusion for patient, thus reserves the regular hour for the alarm 92 warning reminding people that accompanies and attends to.
Alarm 92 can send alarm signal with the form of flash of light and voice message when receiving alarm command,
Entourage is reminded to change dressings.
This utility model is not limited to above-mentioned preferred forms, and those skilled in the art are of the present utility model
Other various forms of products all can be drawn under enlightenment, no matter but in its shape or structure, make any change,
Every have same as the present application or akin technical scheme, all fall within protection domain of the present utility model it
