Abstract
A vacuum assisted fetal extraction apparatus and a monitoring device for use in conjunction therewith. The monitoring device includes a circuit including a timer operably coupled with a switch, which may comprise a differential pressure sensor. The switch is configured to be actuated by the formation of a vacuum to secure the fetal extractor to a fetus. At least partial release of the vacuum releases the switch to stop or pause the timer. The timer may be configured to be reset such that it only records or displays the duration of a specific application of the vacuum device, or it may be configured to record or display a cumulative duration based upon multiple applications of the vacuum device in an absolute sense or during a defined time period. Magnitude as well as the cumulative number of applications of an applied vacuum may also be measured and, optionally, displayed, as may the number of times traction force is applied to an infant during delivery.
