Description
Technical field
The present invention relates to a kind of automatic-exhaust transfusion devices, belong to medical appliance field.
Background technique
Existing general infusion set, in clinical use, the bubble in transfusion catheter must be completely exhausted out by medical staff
It is infused again afterwards.The method generallyd use is, after bottle plug puncture unit is pierced into transfusion bottle stopper, is inverted or squeezes dropping funnel, make medical fluid
Into in dropping funnel, dropping funnel is restored to normal operating condition rapidly again after being filled with the liquid of half or so in dropping funnel, even if such as
This, also often adsorbs bubble, medical staff is also needed to pinch bubble with finger bullet on tube wall, such operating method is relatively complicated, gives medical care
Personnel bring great inconvenience.
Original to solve the problems, such as, Patent No. 201110432748.5 provides solution party from exhaust bubble-proof transfusion device
Case, but after infusion midway stops or replaces medical fluid, if the emptying rate of liquid in dropping funnel, continue to use and need to arrange again
Gas has resistance at this time in infusion pipeline, exhaust velocity can be slack-off, simultaneously because exhaust core feed liquor rooved face is soaked by liquid
Moisten, the surface tension that the liquid in dropping funnel is easy to break through lead channel flows into infusion pipeline, causes dropping funnel liquid level inadequate, institute
To carry out original manual inversion there is still a need for medical staff or squeeze the bleeding of dropping funnel.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is providing a kind of can be achieved repeatedly
Automatically it is vented and is able to maintain the automatic-exhaust transfusion device of certain liquid.
Automatic-exhaust transfusion device of the present invention, including dropping funnel, dropping funnel is interior to be arranged exhaust apparatus, and exhaust apparatus includes row
Gas seat and nut cap, exhaust seat are arranged at the liquid outlet of dropping funnel bottom, hollow equipped with communicating with the liquid outlet in exhaust seat
It is vented core, is vented between core and exhaust seat and is equipped with feed liquor gap, exhaust core side wall is equipped with lead channel, and exhaust seat is equipped with connection
Nut cap is arranged in the inlet opening of dropping funnel inner cavity and feed liquor gap, exhaust seat top, and nut cap is equipped at least one air discharge duct.
Preferably, the lower part of exhaust seat bottom or exhaust seat side wall is arranged in the inlet opening.
Preferably, the lead channel on the inlet opening on the exhaust seat and exhaust core mutually staggers, and avoids the straight of liquid
Impact is connect, is conducive to that the liquid flowed through is exhausted.
Preferably, the air discharge duct in the nut cap can have one and also have it is multiple, can be located at cap side faces,
Nut cap top can be located at.
This transfusion system structure is simple, and hollow exhaust core is equipped in exhaust seat, has between feed liquor between exhaust seat and exhaust core
Gap, exhaust core side wall are equipped with lead channel, and exhaust seat is equipped with inlet opening, and the liquid instilled in dropping funnel can be made to pass through exhaust
Device, and then flow into the infusion pipeline below dropping funnel, the lead channel being vented on core can make the gas-liquid instilled in dropping funnel simultaneously mixed
The gas discharge in object is closed, the setting of nut cap can buffer the liquid for instilling dropping funnel, prevent the generation of secondary bubble in dropping funnel.Row
Inlet opening is set on gas seat, inlet opening especially is set in exhaust seat bottom or the lower part of exhaust seat side wall, when needs second
When secondary exhaust (or subsequent multiple exhaust), liquid, which can cover inlet opening, to be continued to rise, and until the air discharge duct in nut cap, and is passed through
Air discharge duct in nut cap flows into feed liquor gap, then completes air exhausting transfusion process again by exhaust core, while being able to maintain in dropping funnel
Certain liquid level, without any inversion or the operation of extruding dropping funnel.
Compared with the prior art, the invention has the beneficial effects that:
This automatic-exhaust transfusion device structure is simple, easy to use, the feed liquor on inlet opening and exhaust core on exhaust seat
The setting of slot can will enter the discharge of the gas in the gas-liquid mixture in dropping funnel, and intercept bubble fine crushing, on exhaust seat into
Air discharge duct in fluid apertures and nut cap can keep liquid level certain in dropping funnel, so that automatic exhaust is realized repeatedly, when defeated
Liquid midway needs to be not necessarily to manual inversion when secondary exhaust (or subsequent multiple exhaust) or squeezes drop after stopping or replacing medical fluid
Bucket.

Specific embodiment
The embodiment of the present invention is described further with reference to the accompanying drawing:
As shown in figures 1-4, this automatic-exhaust transfusion device includes bottle plug puncture unit 1, conduit 2, dropping funnel 3, infusion pipeline 5, medicine
Liquid filter 6, flow regulator 10, cone joint 9 and intravenous infusion needle 8 (can also be without intravenous infusion needle 8) are set in dropping funnel 3
Exhaust apparatus 4 is set, exhaust apparatus 4 includes exhaust seat 13 and nut cap 11, and exhaust seat 13 is arranged at the liquid outlet of 3 bottom of dropping funnel,
It is equipped with the hollow exhaust core 14 communicated with the liquid outlet in exhaust seat 13, is vented between core 14 and exhaust seat 13 and is equipped between feed liquor
Gap 17, exhaust 14 side wall of core are equipped with lead channel 16, and exhaust seat 13 is equipped with the feed liquor of connection dropping funnel 3 inner cavity and feed liquor gap 17
Hole 15, nut cap 11 is arranged at the top of exhaust seat 13, and nut cap 11 is equipped at least one air discharge duct 12.
Wherein: the lower part of 13 side wall of 13 bottom of exhaust seat or exhaust seat is arranged in inlet opening 15；On exhaust seat 13 into
Fluid apertures 15 and exhaust core 14 on lead channel 16 mutually stagger, avoid the direct impact of liquid, be conducive to the liquid flowed through into
Row exhaust；Air discharge duct 12 in nut cap 11 can have one and also have it is multiple, can be located at 11 side of nut cap, may be alternatively located at lid
11 top of cap.
This transfusion system structure is simple, hollow exhaust core 14 is equipped in exhaust seat 13, between exhaust seat 13 and exhaust core 14
There is feed liquor gap 17, exhaust 14 side wall of core is equipped with lead channel 16, and exhaust seat 13 is equipped with inlet opening 15, can make to instill dropping funnel 3
Interior liquid passes through exhaust apparatus 4, and then flows into the infusion pipeline 5 of 3 lower section of dropping funnel, the lead channel 16 being vented on core 14
The gas instilled in the gas-liquid mixture in dropping funnel 3 simultaneously can be made to be discharged, the setting of nut cap 11 can buffer the liquid for instilling dropping funnel 3
Body prevents the generation of secondary bubble in dropping funnel 3.Inlet opening 15 is set on exhaust seat 13, especially in 13 bottom of exhaust seat or
Inlet opening 15 is arranged in the lower part of 13 side wall of person's exhaust seat, when needing second of exhaust (or subsequent multiple exhaust), liquid meeting
It covers inlet opening 15 to continue to rise, flows into feed liquor until the air discharge duct 12 in nut cap 11, and by the air discharge duct 12 in nut cap 11
Then air exhausting transfusion process is completed by exhaust core 14 again, while being able to maintain liquid level certain in dropping funnel 3, nothing in gap 17
Need the operation of any inversion or extruding dropping funnel 3.
Except above-mentioned points, the bottle plug puncture unit 1 in this infusion apparatus can be plastic puncture also can for metallic piercer or
