Abstract: Disclosed herein are systems, devices, and methods for providing continuous, non-invasive blood pressure monitoring. A wearable monitoring device includes first and second transducer arrays separated by a fixed distance. Each of the transducer arrays includes a plurality of independent transducer elements for transmitting and receiving ultrasound energy. When a user wears the device, the transducers are positioned near the brachial artery. The device operates to measure the transit time of a cardiac pulse through the brachial artery and across the fixed distance between transducer arrays. The measured pulse transit time may then be used for determining pulse wave velocity and/or blood pressure.

Abstract: Disclosed herein are systems, devices, and methods for remotely measuring one or more vital signs of a patient, securely storing and communicating the resulting vital sign data, and configuring the vital sign data for secure access by a healthcare provider computer system to enable remote monitoring of the patients vital signs. One or more vital sign monitoring devices detect patient vital signs and securely transmit the resulting vital sign data to an external computer device such as the patients smart phone or abase station computer device. The external computer device communicates with a server system, such as a secure cloud storage system, which configures the vital sign measurement data and received patient identification data and makes it accessible to one or more healthcare provider computer systems.

Abstract: A monitoring system for determining a user's respiration rate includes a wearable monitoring device for attachment to the user's chest wall. The wearable monitoring device includes a plurality of biometric sensors for generating a plurality of separate biometric data types such as motion data, sound data, and EKG data. A controller is included within the wearable monitoring device and/or is communicatively coupled to the device. The controller is configured to receive the biometric data from the biometric sensors, associate the biometric data of each of the separate biometric data types with one another according to a common sampling timeline to generate a set of multiplexed biometric data, and use the multiplexed biometric data to determine the user's respiration rate.

Abstract: A wearable vital sign monitor. The wearable vital sign monitor includes a band, where the band secures the wearable vital sign monitor relative to a user. The band includes an interior surface, the interior surface being the surface closest to the skin of the user and an exterior surface, the exterior surface opposite the interior surface. The wearable vital sign monitor also includes a first sensor array. The first sensor array is attached to the band and includes at least two sensors. The wearable vital sign monitor further includes a second sensor array. The second sensor array is attached to the band a fixed distance from the first sensor array and includes at least two sensors. The wearable vital sign monitor additionally includes an electronics module. The electronics module is configured to receive a first signal from the first sensor array, receive a second signal from the second sensor array, and transmit the sensor data to an external device.
