ABSTRACT:
A hand-held fetal vacuum extractor combines a pump and handle into a single hand-held unit. This enables a single operator, such as a doctor, to control vacuum using a vacuum pump, and apply traction to a fetus using a single hand. A handle, having a surface for gripping, is connected to a fetal vacuum cup for being suctioned onto a fetal head. A vacuum pump is connected to the handle and includes an activation surface for activating the vacuum pump. The vacuum pump is fluidly coupled to a the vacuum cup and fetal head. The grip surface of the handle and the activation surface of the pump are in such proximity, during operation, that a single human hand can simultaneously grasp the grip surface and contact the activation surface.
