Spreizspektrumverfahren zur Bestimmung von Vitalparametern

DE 102006022120 A1 UPAB: 20071002 NOVELTY - The method involves using the receiver mechanism (105) of a receiver (100) to receive repeating optical signals showing sequences of light from a light source (170) provided inside a transmitter (150). The light from the light source is received based on predetermined time conditions. An extracting mechanism (120) is configured to extract information about vital parameters from the received optical signals, such that the size value of the received sequences of light referring to the vital parameters are obtained from the extracted information. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) Vital parameter determination process; (2) Optical signal generator; and (3) Optical signal generation method. USE - Used in determining vital parameters of an organism, used in plethysmography, pulse oximetry. ADVANTAGE - Provides a spread-spectrum processing applicable for use in plethysmogram-based measuring procedures e.g. plethysmography, pulsoxymetrie, with reduced environmental interferences, light interferences and electromagnetic interferences. Ensures improved parameter measurement due to efficient interference suppression and increased quality of treatment for patients. Ensures reliable patient treatment process and reliable measurement of parameters in critical environments. Ensures higher recovery chances and efficient working process in operating rooms and intensive care units
