Top be socketed with dropper, the bottom that dropping funnel is trapped is socketed with drain pipe road；Described dropping funnel is trapped and is provided with between back-up ring
Buoyancy aid, the bottom of buoyancy aid is provided with groove, and the inwall of groove is provided with annular retaining ring.
It is identical that the degree of depth of described groove highlights the trap height of bottom of dropping funnel with drain pipe road.
It is the primary importance that described buoyancy aid moves that described buoyancy aid covers the drain pipe road mouth of pipe, and detaching the liquid pipeline mouth of pipe is institute
State the second position that buoyancy aid moves.
Described back-up ring is made up of rubber or plastics, and is provided with circular aperture on back-up ring.
It is enclosed within described dropping funnel and set socket place on dropping funnel is provided with annular ledge.
This utility model having the beneficial effects that compared with prior art:
This has the transfusion device of only liquid function at the end of transfusion is soon, the high liquid level (HLL) of medicinal liquid in dropper component gradually
Declining, buoyancy aid declines therewith, and when buoyancy aid drops to primary importance, the mouth of pipe in drain pipe road is just blocked by buoyancy aid, prevents medicine
Liquid flows downward, automatic stopping infusion, it is to avoid because the medicinal liquid in transfusion device is very few, hydraulic pressure is too low, it is to avoid because not having
The situation extracting puncture needle in time and cause patient blood to flow backwards occurs, and improves the security performance of transfusion device, without the need for
Patient often goes to pay close attention to infusion syrup and completes the soonest, and patient can be allowed to have a rest securely when transfusion, and beneficially the state of an illness is extensive
Multiple.

Detailed description of the invention
This have the transfusion device of only liquid function by bottle stopper puncture assembly 1, drain pipe road 2, dropper component 3, infusion pipeline 4,
Flow regulator 5, liquid medicine filter 6, blood back part 7 and outer cone joint 8 are sequentially connected with composition, and outer cone joint 8 is set with
Joint protective sleeve 9, described dropper component 3 is trapped 3-3, back-up ring 3-5, buoyancy aid 3-9 by overlapping 3-2, dropping funnel on dropper 3-1, dropping funnel
Constituting with drain pipe road 3-8, the trap upper end of 3-3 of dropping funnel is socketed on dropping funnel the inner side of set 3-2 lower end, and dropping funnel traps 3-3's
Upper end is stained with back-up ring 3-5, described back-up ring 3-5 by step 3-6 adhesive and dropping funnel is divided into upper and lower two chambers, and upper chamber is
Dropping liquid chamber 3-4, lower chambers is for going out sap cavity room；The top overlapping 3-2 on dropping funnel is socketed with dropper 3-1, and dropping funnel is trapped the bottom of 3-3
It is socketed with drain pipe road 3-8；Described dropping funnel is trapped and is provided with buoyancy aid 3-9 between 3-3 and back-up ring 3-5, and the bottom of buoyancy aid 3-9 sets
Being equipped with groove 3-11, the inwall of groove 3-11 is provided with annular retaining ring 3-7.
It is identical that the degree of depth of described groove 3-11 highlights the trap height of 3-3 bottom of dropping funnel with drain pipe road 3-8.
It is the primary importance that described buoyancy aid 3-9 moves that described buoyancy aid 3-9 covers the drain pipe road 3-8 mouth of pipe, departs from drain pipe
The road 3-8 mouth of pipe is the second position that described buoyancy aid 3-9 moves.
Described back-up ring 3-5 is made up of rubber or plastics, and is provided with circular aperture on back-up ring 3-5.
Described dropping funnel trap 3-3 with dropping funnel on overlap 3-2 socket place be provided with annular ledge 3-10, this annular ledge 3-
10 play spacing effect at socket place.
When using this transfusion device to infuse, time incipient, in dropping liquid chamber 3-4, there is big medicine amount liquid, super
Crossing the height of back-up ring 3-5, buoyancy aid 3-9 departs from due to the drain pipe road 3-8 mouth of pipe of buoyancy with lower section, i.e. buoyancy aid 3-9 is in second
Position；At the end of transfusion is soon, the high liquid level (HLL) of medicinal liquid is gradually reduced in dropper component 3, and buoyancy aid 3-9 declines therewith, when
When buoyancy aid 3-9 drops to primary importance, the drain pipe road 3-8 mouth of pipe is just blocked by buoyancy aid 3-9, i.e. buoyancy aid 3-9 is in first
Put；Now, the groove 3-11 of buoyancy aid 3-9 compresses airtight with the drain pipe road 3-8 mouth of pipe, can effectively prevent medicinal liquid from flowing downward,
Automatic stopping infusion, it is to avoid because the medicinal liquid in transfusion device is very few, hydraulic pressure is too low, the situation causing patient blood to flow backwards is sent out
Problem that is raw, that solve to cause patient blood to flow backwards because of extracting puncture needle the most in time, improves the security performance of transfusion device,
Often go to pay close attention to infusion syrup to complete the soonest without the need for patient, patient can be allowed to have a rest securely, favorably when transfusion
Recovery in the state of an illness.
