SYSTEMS AND METHODS FOR IDENTIFYING A MEDICALLY MONITORED PATIENT

摘要

Systems and methods provided relate to patient sensors and/or patient monitors that recognize and/or identify a patient with physiological signals obtained from the sensor. A scalogram may be produced by applying a wavelet transform for the physiological signals obtained from the sensor. The scalogram may be a three dimensional model (having time, scale, and magnitude) from which certain physiological information may be obtained. For example, unique human physiological characteristics, also known as biometrics, may be determined from the scalograms. More specifically, monitoring the changes in the morphology of the photoplethysmographic (PPG) waveform transforms (e.g., scalogram) may determine patient-specific information that may be used to recognize and/or identify the patient, and that may be used to determine a proper or improper association between the patient and the wireless sensor and/or patient monitor.

主权项

1. A system for facilitating the monitoring of physiologic conditions, comprising:
a medical sensor configured to obtain a physiological signal from a patient; and a processor configured to generate a wavelet transform scalogram of the physiological signal and to compare a characteristic of the scalogram to a stored characteristic to identify the patient associated with the physiological signal.
