Description
Technical field
This utility model relates to a kind of automatic vent dropping funnel, belongs to medical apparatus field.
Background technology
Existing general infusion set, when Clinical practice, medical personnel infuse after the bubble in transfusion catheter must being discharged completely again.The method of usual employing is, after bottle plug puncture unit is thrust transfusion bottle stopper, be inverted or extruding dropping funnel, make medicinal liquid enter in dropping funnel, when rapid again after the liquid about being filled with half in dropping funnel, dropping funnel is returned to normal operating condition, nonetheless, tube wall also often adsorbs bubble, also need medical personnel to pinch bubble with finger bullet, this kind of operational approach is comparatively loaded down with trivial details, brings great inconvenience to medical personnel.
For solving original problem, the patent No. be 201110432748.5 provide solution from aerofluxus bubble-proof transfusion device, but after transfusion midway stops or changing medicinal liquid, if the emptying rate of liquid in dropping funnel, continue use and need aerofluxus again, now existing resistance in infusion pipeline, exhaust velocity can be slack-off, simultaneously because aerofluxus core lead channel surface is by liquid-soaked, the surface tension that liquid in dropping funnel is easy to break through lead channel flows into infusion pipeline, cause dropping funnel liquid level inadequate, so still need medical personnel to carry out the bleeding of original manual inversion or extruding dropping funnel.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and realize repeatedly automatic vent and can keep the automatic vent dropping funnel of certain liquid.
Automatic vent dropping funnel described in the utility model, comprise and be positioned at the intrinsic exhaust apparatus of dropping funnel, exhaust apparatus comprises exhaust seat and block, exhaust seat is arranged on the liquid outlet place of dropping funnel body bottom portion, the aerofluxus core of the hollow communicated with this liquid outlet is provided with in exhaust seat, feed liquor gap is provided with between aerofluxus core and exhaust seat, aerofluxus core sidewall is provided with lead channel, exhaust seat is provided with the inlet opening being communicated with dropping funnel chamber body and feed liquor gap, exhaust seat top arranges block, and block is provided with at least one air discharge duct.
Preferably, described inlet opening is arranged on bottom exhaust seat or the bottom of exhaust seat sidewall.
Preferably, the lead channel on the inlet opening on described exhaust seat and aerofluxus core staggers mutually, and avoid the direct impact of liquid, the liquid be conducive to flowing through is exhausted.
Preferably, the air discharge duct on described block can have one also can have multiple, can be positioned at cap side faces, also can be positioned at block top.
This dropping funnel structure is simple, the aerofluxus core of hollow is provided with in exhaust seat, feed liquor gap is had between exhaust seat and aerofluxus core, aerofluxus core sidewall is provided with lead channel, and exhaust seat is provided with inlet opening, and the liquid in instillation dropping funnel can be made to pass through exhaust apparatus smoothly, and then in infusion pipeline below inflow dropping funnel, lead channel on aerofluxus core can make the gas simultaneously instilled in the gas-liquid mixture in dropping funnel discharge, and the liquid arranging available buffer instillation dropping funnel of block, prevents the generation of Secondary cases bubble in dropping funnel.Exhaust seat arranges inlet opening, particularly bottom exhaust seat or the bottom of exhaust seat sidewall inlet opening is set, when needs second time aerofluxus (or follow-up repeatedly aerofluxus), liquid can cover inlet opening to be continued to rise, until the air discharge duct on block, and flow into feed liquor gap by the air discharge duct on block, then again complete air exhausting transfusion process by aerofluxus core, liquid level certain in dropping funnel can be kept, without the need to any inversion or the operation extruding dropping funnel simultaneously.
The beneficial effect that this utility model is compared with prior art had is:
This automatic vent dropping funnel structure is simple, easy to use, gas in the gas-liquid mixture entered in dropping funnel can be discharged by the setting of the lead channel on the inlet opening on exhaust seat and aerofluxus core, and tackle bubble in small, broken bits, inlet opening on exhaust seat and block on air discharge duct can keep liquid level certain in dropping funnel, thus realize repeatedly automatic vent, when needing secondary exhaust (or follow-up repeatedly aerofluxus) after midway of infusing stops or changing medicinal liquid without the need to manual inversion or extruding dropping funnel.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 3, this automatic vent dropping funnel comprises by dropping funnel lid 2, the dropping funnel body that dropping funnel seat 3 is combined into and be positioned at the intrinsic exhaust apparatus of dropping funnel, dropping funnel lid 2 upper end has injection member 1 (also can not arrange injection member 1), exhaust apparatus comprises exhaust seat 6 and block 4, exhaust seat 6 is arranged on the liquid outlet place bottom dropping funnel seat 3, the aerofluxus core 7 of the hollow communicated with this liquid outlet is provided with in exhaust seat 6, feed liquor gap 10 is provided with between aerofluxus core 7 and exhaust seat 6, aerofluxus core 7 sidewall is provided with lead channel 9, exhaust seat 6 is provided with the inlet opening 8 being communicated with dropping funnel chamber body and feed liquor gap 10, exhaust seat 6 top arranges block 4, block 4 is provided with one or more air discharge duct 5.
Wherein: inlet opening 8 is arranged on bottom exhaust seat 6 or the bottom of exhaust seat 6 sidewall; Inlet opening 8 on exhaust seat 6 and the lead channel 9 on aerofluxus core 7 stagger mutually, avoid the direct impact of liquid, and the liquid be conducive to flowing through is exhausted; Air discharge duct 5 on block 4 can have one also can have multiple, can be positioned at block 4 side, also can be positioned at block 4 top.
This dropping funnel structure is simple, the aerofluxus core 7 of hollow is provided with in exhaust seat 6, feed liquor gap 10 is had between exhaust seat 6 and aerofluxus core 7, aerofluxus core 7 sidewall is provided with lead channel 9, exhaust seat 6 is provided with inlet opening 8, the liquid in instillation dropping funnel can be made to pass through exhaust apparatus smoothly, and then in infusion pipeline below inflow dropping funnel, lead channel 9 on aerofluxus core 7 can make the gas simultaneously instilled in the gas-liquid mixture in dropping funnel discharge, the liquid arranging available buffer instillation dropping funnel of block 4, prevents the generation of Secondary cases bubble in dropping funnel.Exhaust seat 6 is arranged inlet opening 8, particularly bottom exhaust seat 6 or the bottom of exhaust seat 6 sidewall inlet opening 8 is set, when needs second time aerofluxus (or follow-up repeatedly aerofluxus), liquid can cover inlet opening 8 to be continued to rise, until the air discharge duct 5 on block 4, and flow into feed liquor gap 10 by the air discharge duct 5 on block 4, then again complete air exhausting transfusion process by aerofluxus core 7, liquid level certain in dropping funnel can be kept, without the need to any inversion or the operation extruding dropping funnel simultaneously.
