Abstract
An obstetric suction device for vacuum extractors and consisting of a suction device (11) with a connecting mechanism (15) for a suction hose and a traction device (16) attachable to the cup. The object of the invention is to provide a suction cup which does not give right to any pressure force component, regardless of how the tractive force is applied to the cup. This has been attained by making the traction device (16) in the form of a two-point pulling device which is attachable to two attachments (18) disposed in proximity of the opening (12) of the cup and diametrically opposite to one another.
