Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of simple in structure, easy to use and safe from the aerofluxus bubble-proof transfusion device.
the technical solution adopted for the present invention to solve the technical problems is: described from the aerofluxus bubble-proof transfusion device, comprise bottle plug puncture unit, infusion pipeline, dropping funnel, flow regulator, liquid medicine filter, tongs, cone joint and venoclysis needle, it is characterized in that: be provided with exhaust apparatus in dropping funnel, exhaust apparatus comprises exhaust seat, aerofluxus core and block, the bottom of exhaust seat is fixed on the liquid droping port place of dropping funnel bottom and closely cooperates with liquid droping port, be provided with the aerofluxus core of the hollow that communicates with liquid droping port in exhaust seat, be provided with the feed liquor gap between aerofluxus core and exhaust seat, be provided with lead channel on the sidewall of aerofluxus core and exhaust seat, the top of exhaust seat arranges block, block fastens with exhaust seat, the sidewall of block is provided with at least one air discharge duct.
The present invention is simple in structure, be provided with the aerofluxus core of hollow in exhaust seat, the feed liquor gap is arranged between exhaust seat and aerofluxus core, and be equipped with lead channel on the sidewall of aerofluxus core and exhaust seat, can make the liquid that splashes in dropping funnel pass through smoothly exhaust apparatus, and then in the infusion pipeline below the inflow dropping funnel, lead channel on the aerofluxus core can make the gas-liquid mixture that splashes into simultaneously in dropping funnel smoothly gas be discharged in addition, block the liquid that available buffer splashes into dropping funnel is set, prevent the generation of bubble in dropping funnel, use safety, and need not to be inverted or the extruding dropping funnel when using, easy to operate.
Described lead channel is respectively equipped with three on aerofluxus core and exhaust seat, the horizontal sextant angle between the lead channel on the lead channel on adjacent exhaust seat and aerofluxus core is 60 °.Lead channel evenly distributes, and the uniform liquid that splashes into dropping funnel is flowed in the infusion pipeline of dropping funnel below, and be conducive to the liquid of the lead channel of flowing through is carried out aerofluxus.
Described dropping funnel is the injection moulding dropping funnel.First block and exhaust seat are installed during assembling, then snap in the liquid droping port of injection moulding dropping funnel bottom exhaust seat, and then load onto the dropping funnel lid.
Described liquid medicine filter can be the accurate filter below 5.0 μ m, can be also the plain filter of 15 μ m; This liquid medicine filter can be arranged on the end of infusion pipeline, also can be arranged on the position between flow regulator and dropping funnel.
In addition, the bottle plug puncture unit in the present invention is plastic puncture, metal puncture device or plastic-metal mixing perforator.
The beneficial effect that the present invention has is:
Whole simple and reasonable from the aerofluxus bubble-proof transfusion device, need not during use to be inverted or the extruding dropping funnel, flow regulator also need not to cut out, easy to operate, the setting of the lead channel on the exhaust seat in exhaust apparatus, aerofluxus core, block and exhaust seat and aerofluxus core can prevent the generation of bubble, gas in the gas-liquid mixture that enters in dropping funnel can be discharged, the block air discharge duct can avoid being detained gas, and is safe and convenient to use, quick reliable.
