 What inspired Dr. Tydeman's device?
Its sole purpose was to test the effectiveness of a novel device called a Tydeman tube. To understand the desperation of Debra and how the Tydeman tube might help to relieve it requires a brief foray into basic obstetric knowhow. "There are strong opinions about why it happens and what to do, but very little research evidence," says Tydeman, adding that many of these opinions are contradictory. The Tydeman tube is a gadget intended to make this manoeuvre safer and more effective. Between them they came up with a device – the Tydeman tube – to make pushing on the foetus more controlled while simultaneously releasing any vacuum that might be holding it in place.
