Core body temperature sensor and method for manufacturing same

Abstract

The present disclosure concerns a core body temperature sensor for measuring the core body temperature of a body in a non-invasive way via applying the core body temperature sensor to a surface of the body. The core body temperature sensor comprises: at least a first thermistor pair of opposing thermistors across a first thermal insulator; a second thermistor pair, adjacent to the first thermistor pair, of opposing thermistors across a second thermal insulator; and a means to measure blood perfusion. The core body temperature sensor is an essential planar sandwich structure formed of the at least first and second thermistor pairs across the respective first and second thermal insulators sandwiched between opposing carriers. The present disclosure further concerns a method for determining a core body temperature and a method for the manufacturing of a core body temperature sensor.

Description

technical field [0001] The present disclosure relates to core body temperature sensors and methods of manufacturing the same. Background technique [0002] An important parameter of the human body is core body temperature. This temperature can provide information about the state of health and / or the degree of thermal stress to which the subject is subjected. [0003] Hypothalamic and intrathoracic pulmonary artery temperatures are commonly used as criteria for core body temperature. Measuring these temperatures directly is impractical and potentially dangerous because these sites are deeply embedded in the body. There are various techniques that can be used to measure core body temperature. These include conventional contact thermometry, infrared thermometry, radio wave thermometry and thermometry based on heat flow measurements. Routine contact thermometry applied to the rectum is generally considered to provide a reasonably accurate estimate of core body temperature. ...

Problems solved by technology

These heat losses are not accounted for in the following determination of core body temperature, reducing the precision of the reporting probe

Furthermore, the vertical design of the thermal insulator hinders the efficient mass production of the probes, for example, already due to the need to provide capping layers covering the probes such that these capping layers precisely follow the 3D geometry of the thermal insulating layer.
