Patent number: 11963749Abstract: An acoustic sensor attached to a medical patient can non-invasively detect acoustic vibrations indicative of physiological parameters of the medical patient and produce an acoustic signal corresponding to the acoustic vibrations. The acoustic signal can be integrated one or more times with respect to time, and a physiological monitoring system can determine pulse or respiration parameters based on the integrated acoustic signal. The physiological monitoring system can, for instance, estimate a pulse rate according to pulses in the integrated acoustic signal and a respiration rate according to a modulation of the integrated acoustic signal, among other parameters. Further, the physiological monitoring system can compare the integrated acoustic signal or parameters determined based on the integrated acoustic signal with other signals or parameters to activate alarms.Type: GrantFiled: August 30, 2019Date of Patent: April 23, 2024Assignee: Masimo CorporationInventors: Valery G.

Patent number: 11872156Abstract: Continuous core body temperature measurements are made during hypothermic operations, where the core body temperature of the patient is lowered to reduce swelling. Caregivers monitor the patient's core body temperature to prevent damage that can occur to the patient if the patient's core body temperature becomes too low. To accurately determine the core body temperature of the patient, a temperature monitoring system measures the temperature at or near the surface of the patient and through at least a portion of a thermal block at multiple locations.Type: GrantFiled: August 21, 2019Date of Patent: January 16, 2024Assignee: Masimo CorporationInventors: Valery G.
