From the aerofluxus bubble-proof transfusion device
Technical field
The present invention relates to a kind ofly, belong to the medical apparatus field from the aerofluxus bubble-proof transfusion device.
Background technology
Transfusion is a widely used Therapeutic Method in clinical treatment, and safety is the indispensable essential condition of transfusion, but when the transfusion device herb liquid begins to get into dropping funnel; Very easily form gas and mixtures of liquids; This gas-liquid mixture can get into rapidly in the infusion pipeline of dropping funnel below, and the bubble phenomenon when forming transfusion threatens to the healthy of patient; So medical personnel infuse after must the bubble in the transfusion catheter being discharged fully when transfusion again.Usually the method that adopts is after bottle plug puncture unit is thrust transfusion bottle stopper, to be inverted or the extruding dropping funnel; Medicinal liquid is got in the dropping funnel, behind the liquid that charges in the dropping funnel about half, rapidly dropping funnel is returned to normal operating condition again, nonetheless; Also often adsorb bubble on the tube wall; Also need medical personnel to pinch bubble with the finger bullet, this kind operational approach is comparatively loaded down with trivial details, brings great inconvenience to medical personnel.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the present invention will solve 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 the dropping funnel, exhaust apparatus comprises exhaust seat, aerofluxus core and block, and 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 the exhaust seat; Be provided with the feed liquor gap between aerofluxus core and the exhaust seat, be provided with lead channel on the sidewall of aerofluxus core and exhaust seat, the top of exhaust seat is provided with block; Block fastens with exhaust seat, and the sidewall of block is provided with at least one air discharge duct.
The present invention is simple in structure, is provided with the aerofluxus core of hollow in the exhaust seat, between exhaust seat and the aerofluxus core feed liquor gap is arranged; And be equipped with lead channel on the sidewall of aerofluxus core and exhaust seat, can make the liquid that splashes in the dropping funnel smoothly through exhaust apparatus, and then flow in the infusion pipeline of dropping funnel below; Lead channel on the aerofluxus core can make the gas-liquid mixture that splashes into simultaneously in the dropping funnel smoothly gas discharged in addition; Block the liquid that available buffer splashes into dropping funnel is set, prevent the generation of bubble in the dropping funnel, safe in utilization; And need not when using to be inverted or the extruding dropping funnel, 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 lead channel on the adjacent exhaust seat and the aerofluxus core is 60 °.The lead channel uniform distribution evenly flows in the infusion pipeline of dropping funnel below the liquid that splashes into dropping funnel, and helps the liquid of the lead channel of flowing through is carried out aerofluxus.
Described dropping funnel is the injection moulding dropping funnel.Install block and exhaust seat earlier during assembling, again the exhaust seat bottom is snapped in the liquid droping port of injection moulding dropping funnel, and then load onto the dropping funnel lid.
Described liquid medicine filter can be the accurate filter below the 5.0 μ m, also can be 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 the dropping funnel.
In addition, the bottle plug puncture unit among the present invention is plastics perforator, metal puncture device or plastic-metal mixing perforator.
The beneficial effect that the present invention had 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, and is easy to operate; The setting of the lead channel on the exhaust seat in the exhaust apparatus, aerofluxus core, block and exhaust seat and the aerofluxus core can prevent the generation of bubble; Can the gas in the gas-liquid mixture that get in the dropping funnel be discharged, the block air discharge duct can avoid being detained gas, and is safe and convenient to use, quick reliable.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done and to be further described:
Like Fig. 1~shown in Figure 5; From the aerofluxus bubble-proof transfusion device, comprise the exhaust apparatus 5 in bottle plug puncture unit 2, infusion pipeline 3, dropping funnel 4, flow regulator 6, liquid medicine filter 7, tongs 9, cone joint 10, venoclysis needle 11 and the dropping funnel that has protective sleeve 1, described exhaust apparatus 5 comprises exhaust seat 16, aerofluxus core 13 and blocks a shot 15; The bottom of exhaust seat 16 is fixed on the liquid droping port place of dropping funnel 4 bottoms and closely cooperates with liquid droping port; Be provided with the aerofluxus core 13 of the hollow that communicates with liquid droping port in the exhaust seat 16, be provided with feed liquor gap 14 between aerofluxus core 13 and the exhaust seat 16, be provided with lead channel on the sidewall of aerofluxus core 13 and exhaust seat 16; Wherein exhaust seat 16 is provided with three exhaust seat lead channel 12; Aerofluxus core 13 is provided with three aerofluxus core lead channel 17, and the horizontal sextant angle between adjacent exhaust seat lead channel 12 and the aerofluxus core lead channel 17 is 60 °, and the top of exhaust seat 16 is provided with block 15; Block 15 fastens with exhaust seat 16, and the sidewall of block 15 is provided with two air discharge ducts 18.
Wherein, dropping funnel 4 is the injection moulding dropping funnel; Bottle plug puncture unit 2 is plastics perforator, metal puncture device or plastic-metal mixing perforator; The steam vent 8 of band hydrophobic permeable membrane is set on the liquid medicine filter 7, and the liquid medicine filter of selecting for use in the present embodiment 7 is the accurate filter below the 5.0 μ m, and it is arranged on the end of infusion pipeline.
During operation, take off protective sleeve 1, bottle plug puncture unit 2 is inserted the transfusion medicine bottle; Need not be inverted or push dropping funnel 4, also need not close flow regulator 6, liquid flows in the dropping funnel 4 through infusion pipeline 3; Flowing into dropping funnel 4 interior liquid at first splashes on the block 15; Through flowing between dropping funnel 4 bottoms and the exhaust seat 16 along the lateral wall of exhaust seat 16 after the buffering of block 15, liquid gets into feed liquor gap 14 through exhaust seat lead channel 12 then, because the surface tension and the capillarity of liquids and gases; Elder generation's aerofluxus body; Get into the inside of aerofluxus core hollows when liquid level continues to break through when rising covers aerofluxus core 13 surface tension liquid through aerofluxus core lead channel 17, the air discharge duct 18 of block 15 can avoid being detained gas, and keeps certain liquid; Liquid is infused in patient's body through venoclysis needle 11 through the infusion pipeline of the dropping funnel 4 belows liquid medicine filter 7 of flowing through.
