An obstetric vacuum extractor for aiding fetal passage through the birth canal has a vessel which comprises an evacuable vessel chamber open to one side, and on which a pulling device is fastened, characterized in that the vessel (1) is divided into at least two vessel chambers (1', 1") open to one side, which can be evacuated separately.
In a fetal extractor having a bell-shaped chamber designed for mounting an open side thereof on the head of a fetus, means for creating a vacuum within said chamber to affix the extractor to the fetal head, and means for pulling on said chamber to facilitate movement of the fetus through the birth canal, the improvement which comprises:
- a second chamber having an open side which is designed for mounting on the head of a fetus and which surrounds the open side of the bell-shaped chamber when the extractor is mounted on the fetal head, and means for separately creating a vacuum in the second chamber to affix the extractor to the fetal head.
A method of extracting a fetus from a birth canal comprises the steps of:
- (a) positioning a fetal extractor having at least two evacuable chambers, open to the same side with that open side against the head of the fetus;
- (b) separately creating a vacuum in each of the chambers to draw the extractor and fetus into a coupled relation;
- and
- (c) exerting a force on the extractor to facilitate movement of the fetus coupled thereto through the birth canal.
