International Classification:

A61B 5/00

US Classification:

600561

Abstract:

Methods, systems, and related computer program products for are described for non-invasive detection of intracranial pressure (ICP) variations in an intracranial compartment of a patient. Optical radiation is propagated transcranially into the intracranial compartment, and optical radiation that has migrated through at least a portion of the intracranial compartment and back out of the cranium is detected. At least one signal representative of the detected optical radiation is processed to extract therefrom at least one component signal that varies in time according to at least one of an intrinsic physiological oscillation and an externally driven oscillation in the patient. Examples of suitable intrinsic physiological oscillations include intrinsic respiratory and cardiac oscillations. Examples of suitable externally driven oscillations include ventilated respiratory oscillations and externally mechanically induced oscillations. The extracted component signal is then processed to generate an output signal representative of the ICP variations in the intracranial compartment.

International Classification:

A61B 5/1455

US Classification:

600323

Abstract:

Methods, systems, and related computer program products for optically monitoring a chromophore level in a body part of a patient are described. An optical source introduces optical radiation into the body part, and an optical detector receives optical radiation that has propagated through at least a portion of the body part and produces a first signal representative of the received optical radiation. The first signal is processed to produce a chromophore level metric, which is output on a user display, and is further processed to produce a second signal known to exhibit measurably significant timewise fluctuations corresponding to at least one intrinsic physiological oscillation of the patient when the optical source and the optical detector are in proper optical coupling with the body part. An error condition indication is provided if the measurably significant timewise fluctuations are not present in the second signal.

International Classification:

A61B 5/04

US Classification:

600373

Abstract:

Transcutaneous safety electrode assemblies are described that can include a conducting electrode having a sharp end to penetration of the skin of a patient, and a shielding member that is deployable by a user so as to shield the sharp end of the electrode after the electrode is removed from the skin. The shielding member can be deployed by retracting the sharp end of the electrode a protective housing, assisted by spring force provided by the electrode wire so as to self-retract into the protective housing. The deployment and disengagement can be via push button action, and the electrode assembly can be self-retaining on the patient's skin while deployed.
