Device for detecting a pressure, suitable for cooperating with the hand or an obstetrical instrument, in particular a cephalic spoon—associated obstetrical instrument, glove and assistance device

A device for detecting an exerted pressure, comprising:

• a detector on which a pressure is exerted;
• a transducer connected to said detector;
• and
• an elastically deformable shell of biocompatible and sterilizable material, said elastically deformable shell having
• two opposing walls, and
• an insertion opening at least partially defined by an edge of each of said opposing walls, and
• wherein said detector comprises at least one elastically deformable tube comprising a portion disposed in said elastically deformable shell, said at least one elastically deformable tube being closed at one end and filled with a fluid, the other end of said at least one elastically deformable tube being open, disposed outside said elastically deformable shell and connected to said transducer,
• wherein said elastically deformable shell has a shape configured to contact an outer edge of a gripping instrument or a hand, when said elastically deformable shell is mounted to said instrument or to said hand, and
• the portion of said at least one elastically deformable tube disposed in the elastically over at least 50% of an inner deformable shell extends perimeter of said elastically deformable shell, and over zones of the elastically deformable shell configured to receive gripping zones of said instrument or hand, said at least one elastically deformable tube thus being configured to detect a variation in the pressure exerted on said at least one elastically deformable tube by said instrument or said hand.
