摘要

Controlled decompression device, special to promote the intrauterine life of the fetus and to predispose the pregnant woman to the expulsion while maintaining the abdominal wall raised throughout the period in which uterine contractions are perceived by the pregnant woman, characterized by the fact that it comprises: a wide bell or receptacle, of substantially ellipsoidal plant provided with a suction nozzle passing through it and of a hermetic sealing gasket attached to the edge on which it is supported, a pneumatic depressant pump driven by an electrical system, a connection flexible tubular that puts in communication the suction duct of the pump with the suction nozzle of the aforementioned bell, a switch or contactor connected to the power line of the electrical system that drives the said vacuum pump. The substantially ellipsoidal base of the bell or receptacle, provided with elastic seal can be adhered to the abdomen of the pregnant woman, so that the sections of smaller radius of said base are supported respectively, one on the pubic arch and the other immediately below of the costal arch. With the start-up of the pump, a depression is obtained inside the bell or receptacle that causes the gradual elevation - up to the desired limit - of the abdominal wall of the pregnant woman that is circumscribed by the base of the bell.
