A suction cap intended to be applied to the scalp of a foetus to facilitate vaginal or Caesarean section delivery by traction. It typically has a soft liner to prevent tissue damage, a connection to the vacuum source, a handgrip for the clinician to apply traction, and may include a vacuum release valve and fluid retention trap. Suction may be provided by an electrically-powered suction pump, the hospital central vacuum system, or a hand-operated vacuum pump. It is typically used for dystocia, uterine inertia, maternal exhaustion, or maternal/foetal distress. This is a reusable device.
