APARATO PARA MEDIR LA PRESION EN EL INTERIOR DE UNA CAVIDAD CORPORAL.

摘要

A catheter is disclosed for measuring the intrauterine pressure of a woman in labor. It comprises an elongated flexible tube filled with liquid and having one end apertured to permit the liquid therein to communicate with bodily fluids in the uterus; the other end is sealed by a relaxed diaphragm. The catheter tube is inserted into a curved guide tube which is scored at the end adjacent the apertured end of the catheter to permit the catheter to be extended from the guide tube. The guide tube is also scored along its length to permit a portion of the wall of the guide tube to be peeled away leaving a longitudinal slot through which the catheter can be passed after insertion into the uterus. The catheter and guide tube are disposed in a liquid-tight envelope, the open end of which is sealed about the catheter to prevent escape of the liquid within the catheter. A leg plate for supporting a pressure transducer includes means for removably connecting the catheter to the transducer and means for removably attaching the leg plate to the skin of the patient.
