Abstract
The childbirth-assisting device uses an automatically synchronized expandable pneumatic girdle to externally augment the secondary force of labor. The girdle through which the pressure is applied is fitted around the abdomen of the woman. An inflatable bladder within the girdle is inflated to create a downward pressure on the abdomen upon detection of a contraction. An external pressure monitor is used to detect contractions to provide a signal for synchronizing inflation of the girdle. The external pressure monitor includes a solid state force sensor embedded within a pliable housing which is conformable to the patient's abdomen to improve accuracy.
