Membrane puncturing aspirator with drainage shield

A funnel-shaped aspirating device for aspirating a region of a patient, said device comprising:

• a funnel-shield including a mouth, a shaft, and a chamber between the inner and outer spaced-apart walls for aspirating fluids, a plurality of suction ports disposed in the inner wall of said funnel-shield communicating with said chamber, and at least one opening in the inner wall of said shaft of the funnel-shield for communicating with a source of negative pressure, the mouth of said funnel-shield being anatomically contoured to mate with the lower uterine segment of a patient, said funnel-shield being transparent in at least a portion thereof to permit visual observation of the region of aspiration;
• and
• a tubular aspirator means having a puncture end and a discharge end, said tubular aspirator means comprising an elongated hollow shaft adapted to be slidably circumcased within the shaft of said funnel-shield, said tubular aspirator means including at the puncture end thereof a membrane puncture means and a fluid inlet port, said tubular aspirator means having at least one relief port therein for communicating with a common vacuum source that supplies negative aspirating pressure to both said funnel-shield and said tubular aspirator means when said relief port on the tubular aspirator means and the opening in the inner shield shaft are in alignment.
