ABSTRACT:
The present invention aids a person who is assisting with fetal extraction by monitoring and recording the pressure inside a vacuum device. In one embodiment, the invention is a pump-attachable device for monitoring and recording a pressure in a vacuum device that includes an adapter enabled to attach to a pressure gauge receiver of an electric pump, and a cable coupled to the pressure transducer which in enabled to attach to a monitor for recording a detected pressure. In yet another embodiment, the invention is a method of using a recording device for recording a pressure in a vacuum device. The invention includes coupling a monitor to the vacuum device, calibrating the monitor, and recording the pressure to produce a record.
