ABSTRACT:
A device, system, and method for determining the sensing performance of pressure-sensing devices. The device generates dynamic pressure waveforms that enable researchers and medical personnel to accurately assess the characteristics and performance of a particular pressure-sensing device. The system and methods allow for comparison of performance between two or more pressure-sensing devices, including catheter tip pressure transducers and fluid-filled catheters. The system may also be used to practice priming and preparing catheters for insertion into a living body, as the system provides immediate feedback that may indicate the presence of air in the system.
