ABSTRACT:
A transducer-tipped intrauterine pressure catheter system for measuring, and delivering to an external monitor a signal representative of, the pressure in the uterus of a woman in labor. The system has a disposable catheter with an affixed asymmetric tip. A disposable, slotted, C-shaped introducer engages and positions the catheter. A reusable monitor cable has a second connector (which engages a first connector on the end of the catheter) on one end and a monitor connector (which engages the monitor) on its opposite end; the monitor cable transmits electrical signals from the first connector to the monitor. A test member is proximate the monitor connector on the monitor cable. The test member includes test circuitry assuring that the monitor cable, the second connector, and the monitor connector are operational. The test member also includes circuitry to "zero" the system. The system may also have a disposable luer fitting engaging the amnio lumen of the catheter and providing direct communication, through the amnio lumen, into the uterus. The luer fitting allows fluid samples to be withdrawn from, and fluids to be infused into, the uterus. An anti-bacterial coating may be bonded to the catheter, the tip affixed to the catheter, and the introducer.
