April 10, 2005. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3766908 Data acquisition, storage and display system Respiration data acquisition, conversion and display system Infant bed and apnea alarm Crib death detector Detection and monitoring device Portable device for measuring heartbeat rate with compensation for extraneous signals Method and system for measuring rate of occurrence of a physiological parameter Method of monitoring patient respiration and predicting apnea therefrom Respiration monitor InventorsAssigneeApplicationNo. 06/753069 filed on 04/10/1985US Classes:600/529, Respiratory600/484, Detecting respiratory condition600/534, Detecting body movement attending breathing600/536Detector responsive to movement induced variation in impedance of body to electric currentExaminersPrimary: Coven, Edward M.Attorney, Agent or FirmInternational ClassesA61B 5/08 (20060101)G06F 19/00 (20060101) AbstractThe ventilation monitor of this invention includes a plurality of discrete sensors and a plurality of independent channels for processing the input signals from each of the discrete sensors. The principle category of sensor used in conjunction with this ventilation monitor is capable of the reception of information associated with breathing and cardiovascular movement. A second category of the sensor used in conjunction with this ventilation monitor is capable of the reception of audible sounds associated with breathing. Each of the individual input signals from these sensors is initially verified as being indicative of the sensation being monitored and, thereafter, compared in real time with one another and criteria stored within a microprocessor. The purpose of the comparison is to verify a normal breathing pattern and signal an alarm when the breathing pattern is abnormal. The ventilation monitor is also provided with means to dynamically adjust the gain and frequency response of each channel to accommodate changes in the monitored subject's position and physiological states.Other References
