Abstract: The present invention relates to devices and methods for measuring vascular deficiency using Doppler ultrasound detection. Embodiments can be used to monitor the condition of surgical tissue flaps or other conditions in which obstruction in the vascular system can impact patient health. The systems can include a Doppler ultrasound probe, a color probe, a temperature probe, and/or other suitable probes to measure blood volume and perfusion status of a tissue region. The systems and methods can be used to monitor flaps after flap transplant surgeries. The systems and methods can automatedly assess tissue condition and alert the patient or medical staff if the condition has fallen below a threshold indicating occlusion of a blood vessel. One or more additional sensors can be integrated into a probe to measure vascular conditions and a metric can be computed based on sensed data.

Abstract: Systems, devices, and methods of the present application relate to the diagnostic measurement of condition for pressure ulcers. Preferred embodiments utilize pressure measurements at body locations to determine a diagnostic pressure ulcer value. A pressure sensor device generates patient pressure data that is processed by a data processor which utilizes a diagnostic function to determine the diagnostic value that indicates whether corrective action is needed to prevent pressure ulcer formation. One or more sensor devices can be attached to a patient to measure to transmit data for further processing.

Abstract: A non-invasive system for measuring the concentration of an analyte in an absorbing matrix is described. The system directs a beam of radiation at the matrix. The beam consists of a series of successive alternate pulses of electro-magnetic radiation, one of which is highly absorbed by the analyte and the other of which is non-absorbed. The transmitted or reflected beam is optically detected and an electrical signal proportional to beam intensity is used to adjust the beam intensity and as a measure of analyte concentration.

Abstract: A non-invasive system for measuring the concentration of an analyte, such as glucose, in an absorbing matrix is described. The system directs beams of light at the matrix using an analyte sensitive wavelength and an analyte insensitive wavelength. The principles of photoplethysmography are applied to measure the change in light intensity caused by matrix absorption before and after the blood volume change caused by the systolic phase of the cardiac cycle. The change in light intensity is converted to an electrical signal which is used to adjust the light intensity and as a measure of analyte concentration.
