International Classification:

A61B 5/00

Abstract:

Medical patient monitoring sensor devices including a disposable sensor assembly and a reusable pairing device are disclosed. The disposable sensor assembly can collect patient physiological data and provide power for the reusable pairing device.

Abstract:

An optical physiological sensor configured to be secured to a user's nose includes a first prong configured to be positioned proximate an outside portion of the nose, a second prong configured to be positioned proximate an inside portion of the user's nose, a winged portion coupled to the first prong and configured to contact tissue of the user, one or more emitters configured to emit light of one or more wavelengths into the tissue, and one or more detectors configured to detect at least a portion of the light emitted from the one or more emitters after attenuation through at least a portion of the tissue. In some configurations, the winged portion comprises a width that is greater than a width of the second prong. In some configurations, at least a portion of the winged portion is curved toward the second prong.

A61B 5/00

Abstract:

A wearable device configured to secure to skin of a user and noninvasively measure body temperature of the user can include first and second pairs of temperature sensors configured to generate one or more signals responsive to detected thermal energy, a thermally conductive element positioned at least partially between the second pair of temperature sensors, and one or more hardware processors configured to receive the one or more signals generated by each of said first and second pairs of temperature sensors and determine one or more body temperature values of the user based on at least comparisons between different ones of the first and second pairs of temperature sensors. In some implementations, the wearable device includes thermally conductive probes for transmitting thermal energy toward ones of the first and second pairs of temperature sensors and a substrate positioned between the probes and the skin.

International Classification:

A61B 5/024
A61B 5/00

Abstract:

An optical physiological sensor can be integrated into a wearable device and can comprise a substrate having an optical center, a first emitter group of light emitting diodes (LEDs) positioned adjacent to the optical center of the substrate and spaced at an offset from the optical center, a second emitter group of LEDs positioned adjacent to the optical center of the substrate at an offset to the optical center and spaced at an offset from the optical center opposite the first emitter group of LEDs relative to the optical center, and a plurality of detectors arranged in a spatial configuration that surrounds the first and the second emitter group. Each of the plurality of detectors can be positioned on the substrate a same distance away from the optical center of the substrate.

International Classification:

A61B 5/1455
A61B 5/00

Abstract:

A wearable health monitoring device can include a physiological parameter measurement sensor or module configured to be in contact with a wearer's skin when the device is worn by the wearer on the wrist. The physiological parameter measurement sensor can noninvasively and optionally continuously measure one or more physiological parameters, for example, the oxygen saturation, of the wearer. The sensor can include a convex curvature to improve pressure, and therefore optical coupling, between the wearer's skin and the physiological parameter measurement sensor while balancing the pressure and the wearer's comfort. The sensor can include a light barrier between emitters and detectors and other light barriers to improve signal strength and reduce noise.

International Classification:

A61B 5/00

Abstract:

A band configured to apply a force to a physiological sensor on a portion of a user's body can include an elastic segment, a first indicator, and a second indicator. The elastic segment can have a first end and a second end opposite the first end, and a first portion of the elastic segment can be secured to a second portion of the elastic segment to form a closed loop that can at least partially secure the physiological sensor to the portion of the user's body when in use. The first and second indicators can be spaced apart from one another and positioned along the elastic segment. The first indicator can be positioned closer to the first end than the second indicator. A relative distance between the first and second indicators can provide an indication of a desired stretch of the elastic segment.

Abstract:

A non-invasive, optical-based physiological monitoring system is disclosed. One embodiment includes an emitter configured to emit light. A diffuser is configured to receive and spread the emitted light, and to emit the spread light at a tissue measurement site. The system further includes a concentrator configured to receive the spread light after it has been attenuated by or reflected from the tissue measurement site. The concentrator is also configured to collect and concentrate the received light and to emit the concentrated light to a detector. The detector is configured to detect the concentrated light and to transmit a signal representative of the detected light. A processor is configured to receive the transmitted signal and to determine a physiological parameter, such as, for example, arterial oxygen saturation, in the tissue measurement site.
