Abstract: A probe for a dermal phase meter includes a handle with an extension that terminates with a displaceable center conductor. A replaceable tip attaches to the distal end of the extension and includes a center conductor that engages the center conductor in the extension and an outer conductor that establishes electrical connection through the extension. Substituting different replacement tips provides a probe with an articulation capability. Probe tips with a layer of a patient compatible, compressible elastomer overmolded onto the outer conductor provides insulation and minimizes the potential for irritating tissues during a measurement in an anatomical cavity.

Abstract: A patient monitoring system including a sensing-recording device that attaches to a patient and a probe utilized by attending personnel at a trauma site. After an initial interaction between the probe and the sensing-recording device, the sensing-recording device samples one or more physiological parameters and stores time stamped readings in a first memory. The probe is adapted to take other measurements including pulse data, download the data from the first memory of the sensing-recording device, manipulate the collective data and return data to a second memory in the sensing-recording device. The probe is also adapted to combine data from the sensing-recording device and its pulse data to provide a blood pressure measurement.
