Abstract

An obstetretic aspirator device for puncturing amniotic membranes and draining fluids therefrom comprising a funnel-shield (20) serving as a drainage cup and fluid confinement shield and puncture-type tubular aspirator (10) slideable mounted within an elongated shaft (24) of the funnel-shield for puncturing the amniotic membrane. The inner funnel wall (21) of the funnel-shield includes a plurality of suction ports (22) for draining fluids. A common vacuum source connected to the discharge end (18) of the tubular aspirator (10) communicates with both the tubular aspirator (10) and the funnel-shield (20) through the mating openings. The tubular aspirator (10) can be separated from the assembly for sole use as a conventional aspirator. The funnel-shield (20) comprises a pair of spaced apart superposed funnels walls (21 and 23) having a vacuum chamber (27) therebetween which chamber communicates with a vacuum chamber of the tubular aspirator through mating openings (19 and 25). In use, the funnel-shield is placed over the female peritoneal region and puncture-type tubular aspirator (10) is driven forwardly to puncture the amniotic sac whereby amniotic fluids are both confined to an area within the mouth of the funnel-shield and drained by the suction ports contained in the funnel-shield.
