Patent number: 11951186Abstract: Some embodiments disclosed herein pertain to indicator compounds used to detect the presence of and/or an amount of an analyte. In some embodiments, the indicator compounds are fusion proteins. In some embodiments, when the analyte binds to the indicator compound, the indicator compound undergoes a conformational change. In some embodiments, the conformational change results in a luminescent signal that allows quantification of the amount of analyte present.Type: GrantFiled: October 23, 2020Date of Patent: April 9, 2024Assignee: Willow Laboratories, Inc.Inventors: Venkatramanan Krishnamani, Sergei Petrovich Balashov, Kevin Hughes Pauley, Ruiqi Long, Hung The Vo

Patent number: 11944415Abstract: A blood pressure measurement system is provided that includes an inflatable cuff, a valve assembly and chamber assembly. The chamber assembly can house a gas canister for providing gas to the inflatable cuff. The valve assembly can include a valve having a high pressure cavity, a low pressure cavity, and a channel providing a gas pathway between the high pressure cavity and the low pressure cavity. The valve assembly can further include a channel cover and spring in the high pressure cavity. The spring can exert a force on the channel cover to create a seal between the high pressure cavity and the channel. The valve assembly can further include a rod extending through the channel and exerting a force on the channel cover to create a gas pathway between the high pressure cavity and the channel.Type: GrantFiled: March 3, 2021Date of Patent: April 2, 2024Assignee: MASIMO CORPORATIONInventors: Cristiano Dalvi, Marcelo M.

Patent number: 11925445Abstract: A method of determining blood pressure measurements includes inflating a cuff, receiving an indication of pressure inside the cuff during inflation, determining a blood pressure based at least in part on the received indication, assigning a confidence level to the blood pressure, and determining whether the confidence level satisfies a threshold confidence level. Based at least on a determination that the confidence level satisfies a threshold confidence level, the method can include causing a display to display the blood pressure. Based at least on a determination that the confidence level does not satisfy a threshold confidence level, the method can include deflating the cuff, receiving an indication of pressure inside the cuff during deflation, determining another blood pressure, and causing a display to display a blood pressure.Type: GrantFiled: March 3, 2022Date of Patent: March 12, 2024Assignee: Masimo CorporationInventors: Marcelo Lamego, Massi Joe E.

Patent number: 11877824Abstract: A modulated physiological sensor is a noninvasive device responsive to a physiological reaction of a living being to an internal or external perturbation that propagates to a skin surface area. The modulated physiological sensor has a detector configured to generate a signal responsive to the physiological reaction. A modulator varies the coupling of the detector to the skin so as to at least intermittently maximize the detector signal. A monitor controls the modulator and receives an effectively amplified detector signal, which is processed to calculate a physiological parameter indicative of the physiological reaction.Type: GrantFiled: March 22, 2021Date of Patent: January 23, 2024Assignee: Masimo CorporationInventors: Marcelo Lamego, Cristiano Dalvi, Hung The Vo

Patent number: 11864890Abstract: An optical measurement device includes a light source, a first detector, and a second detector. The light source emits light to a measurement site of a patient and one or more detectors detect the light from the light source. At least a portion of a detector is translucent and the light passes through the translucent portion prior to reaching the measurement site. A detector receives the light after attenuation and/or reflection or refraction by the measurement site. A processor determines a light intensity of the light source, a light intensity through a tissue site, or a light intensity of reflected or refracted light based on light detected by the one or more detectors. The processor can estimate a concentration of an analyte at the measurement site or an absorption or reflection at the measurement site.Type: GrantFiled: August 5, 2020Date of Patent: January 9, 2024Assignee: Cercacor Laboratories, Inc.Inventors: Kevin Pauley, Cristiano Dalvi, Hung Vo, Jesse Chen, Ferdyan Lesmana, Jeroen Poeze, Sean Merritt

Patent number: 11766198Abstract: The present disclosure describes example systems, methods, apparatuses, and medical devices for obtaining physiological parameter data from a wearable patient monitoring device. An example patient monitoring device can include an emitter and a detector. The emitter can emit light through tissue of a patient. The detector can sense the light after it passes through and is attenuated by the tissue and can generate a signal indicative of the sensed light. When the patient monitoring device is attached to or worn by the patient, the emitter and detector are aligned such that the light from the emitter travels through an opening between a first bone and a second bone of the patient prior to being sensed by the detector.Type: GrantFiled: February 1, 2019Date of Patent: September 26, 2023Assignee: Cercacor Laboratories, Inc.Inventors: Kevin Hughes Pauley, Hung The Vo, Mathew Paul

Patent number: 11751773Abstract: A noninvasive physiological sensor for measuring one or more physiological parameters of a medical patient can include a bump interposed between a light source and a photodetector. The bump can be placed in contact with body tissue of a patient and thereby reduce a thickness of the body tissue. As a result, an optical pathlength between the light source and the photodetector can be reduced. In addition, the sensor can include a heat sink that can direct heat away from the light source. Moreover, the sensor can include shielding in the optical path between the light source and the photodetector. The shielding can reduce noise received by the photodetector.Type: GrantFiled: February 28, 2020Date of Patent: September 12, 2023Assignee: Masimo CorporationInventors: Massi Joe E.
