The present document discloses a solution for estimating blood pulse wave characteristics by using multiple measurement locations of a human body. According to an aspect, a method includes detecting, in a first measurement signal measured by a first heart activity sensor associated with a first location of a human body, a first occurrence of a blood pulse wave; detecting, in a second measurement signal measured by a second heart activity sensor from a second location of the human body different from the first location, a second occurrence of the blood pulse wave; estimating, on the basis of said detections synchronized to a common clock, time characteristics of the blood pulse wave; and computing, on the basis of said time characteristics, a metric representing a physiological condition of the human body.

A system for monitoring a vascular access is provided. The system includes a wearable vascular access monitor which can be a sleeve or other protective covering fitted with two or more sensors for obtaining physiological measurements at different locations from the vascular access. The sleeve or other protective covering is also fitted with an ultra-low power processor for relaying the physiological measurements to a patient's mobile phone. The patient's phone can evaluate the physiological measurements to determine a state of the vascular access, and if the physiological measurements fall out of nominal ranges, the patient's phone can alert a clinic, nurse, or physician. The system can be used to monitor fistulas or grafts used for hemodialysis or peritoneal dialysis.

A multi-sensor interactive patient care pod is disclosed herein. In one embodiment the system may comprise a telemedicine pod having a plurality of physiological sensors and an integrated computing device allowing medical practitioners to remotely gather increased patient information and provide advanced levels of healthcare and service. The system may have sensors for measuring body weight, heart rate, body temperature, blood pressure, breathing rate, oxygen saturation, and any other appropriate parameters. The multi-sensor interactive patient care pod may comprise an enclosed pod in a first orientation, and may open by the combined sliding of its front cowling and lifting of its top cowling to allow patient ingress and egress. The system may further comprise a mobile device that can be placed in any appropriate location, and may further integrate smart technologies such as machine learning, voice and face recognition, self-cleaning, self-driving, and self-locking technologies.

Disclosed are devices and methods for estimating blood pressure, which implement a pulse-transit-time-based blood pressure model that can be calibrated. Some implementations provide reliable and user friendly means for calibrating the blood pressure model using blood pressure perturbation methods and multiple sensors.

Disclosed are devices and methods for non-invasively measuring arterial stiffness using pulse wave analysis of photoplethysmogram data. In some implementations, wearable biometric monitoring devices provided herein for measuring arterial stiffness have the ability to automatically and intelligently obtain PPG data under suitable conditions while the user is engaged in activities or exercises. In some implementations, wearable biometric monitoring devices are provided herein with the ability to remove PPG data variance caused by factors unrelated to arterial stiffness. In some implementations, wearable biometric monitoring devices have the ability to perform PWA while accounting for the user’s activities, conditions, or status.

A system and method for controlling an emitter assembly comprising a single electromagnetic radiation source for visualizing a surgical site. The emitter assembly comprises a light valve assembly that is coupled to a control circuit. The emitter assembly is configured to emit visible light, infrared radiation, or a combination thereof in either structured or unstructured formats. The control circuit is configured to control the light valve assembly to control which emitter of the emitter assembly is emitting electromagnetic radiation. The light valve assembly can include light valves for controlling whether an emitter receives electromagnetic radiation. Further, the control circuit can control the wavelength of the electromagnetic radiation emitted by the source in accordance with which emitter is receiving electromagnetic radiation.

A stroke detection system operative to detect strokes suffered by mobile communication device users, the system including a hardware processor operative in conjunction with a mobile communication device having at least one built-in sensor. The hardware processor is configured to, repeatedly and without being activated by the device's user, compare data derived from the at least one sensor to at least one baseline value for at least one indicator of user well-being, stored in memory accessible to the processor and/or make a stroke risk level evaluation; and/or perform at least one action if and only if the stroke risk level is over a threshold.

The present invention relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used disposables, thereby allowing accurate and safe use and convenient maintenance.
