Abstract
A measurement device may be wound around the arm of a wearer. The measurement device includes: —on a first, internal, face at least three skin temperature sensors extending over at least one portion of a peripheral line of the measurement device, in a first zone (Z33) of the device; —on a second, external, face, in a second zone (Z34) of the device, at least one cavitary temperature sensor for measuring a temperature in or close to the armpit. Zones (Z33, Z34) are arranged at least partly opposite one another or are substantially adjacent.
Core Innovation
The invention concerns a non-invasive measurement device for measuring a plurality of temperatures with an aim of determining a core internal temperature of a human being wearing the measurement device. The measurement device comprises a first face and a second face opposite the first face, configured to be able to be in a worn configuration in which the measurement device is at least partially wound over itself and forms at least one cylindrical portion having an axis (Z), substantially merged with an axis of an arm, and intended to at least partially encircle the arm in a vicinity of a corresponding armpit, with the first face in contact with a skin of the arm.
The device includes at least three skin temperature sensors positioned on the first face in a first zone, extending substantially over at least part of a peripheral line of the measurement device in the worn configuration. It also includes at least one cavity temperature sensor configured to measure a temperature in the armpit, arranged on the second face in a second zone, with the cavity temperature sensor linearly displaced from the at least three skin temperature sensors and physically connected to the skin temperature sensors by the measurement device.
The measurement device is configured to be able to be in an unworn configuration in which the measurement device is flat, and it further comprises at least one proximal temperature sensor configured to measure a surrounding temperature in an immediate vicinity of the arm. The proximal temperature sensor is arranged on or near the second face and is linearly displaced from the at least three skin temperature sensors, with the distance on the device between a skin temperature sensor and the at least one proximal temperature sensor greater than 10 cm in the unworn configuration.
Claims Coverage
The independent claims present one inventive feature set focused on a multi-sensor temperature arrangement for determining a core internal temperature, with specific device geometry and placement constraints.
Armband wound band with merged arm axis and opposed sensor zones
A measurement device having first and second opposite faces configured for a worn configuration that forms a cylindrical portion with axis (Z) substantially merged with an arm axis, intended to at least partially encircle an arm near a corresponding armpit so that the first face is in contact with arm skin; with a first zone of skin temperature sensors and a second zone of at least one cavity temperature sensor arranged so that they at least partly face each other or are substantially adjacent.
Three skin sensors plus armpit cavity sensor linearly displaced and physically connected
At least three skin temperature sensors on the first face in a first zone extending substantially over at least part of a peripheral line in the worn configuration, and at least one cavity temperature sensor on the second face in a second zone linearly displaced from the at least three skin temperature sensors and physically connected to the skin temperature sensors by the measurement device.
Proximal temperature sensor separated from skin and cavity zones
At least one proximal temperature sensor arranged on or near the second face to measure surrounding temperature in an immediate vicinity of the arm, linearly displaced from the at least three skin temperature sensors, with the measurement device configured in an unworn flat configuration such that the distance on the device between a skin temperature sensor and the at least one proximal temperature sensor is greater than 10 cm.
Overall, the claims center on device geometry and sensor placement: a wound, armband-like band that merges its axis with an arm axis; at least three skin temperature sensors; an armpit cavity temperature sensor on the opposite face; and a proximal temperature sensor separated by more than 10 cm from the skin sensors when the device is flat.
