Embodiment Construction

[0016] The invention relates to a high-speed and precise temperature measuring device especially for measuring the temperature of a human body. The device of the present invention is also useful for measuring animal body temperature and measuring the temperature of any low thermal conductivity chambers.

[0017] The device of the present invention comprises:

[0018] (a) A slender temperature probe. The probe is intended to be inserted into a body cavity (in the present invention the word "body cavity" also refers to the armpit; oral cavity and rectum). The stylet has a rounded insertion end for safe insertion into sensitive body cavities.

[0019] (b) First temperature sensor. The first sensor is located below the surface of the probe near the insertion end (to minimize insertion depth).

[0020] (c) at least one second temperature sensor. The second sensor is located within the probe and is parallel to the first sensor.

[0021] (d) A thermal insulation component. The...

Abstract

The present invention relates to a high speed accurate temperature measuring device especially useful for measuring human body temperature, comprising (a) an elongated temperature probe, (b) a first temperature sensor located beneath the surface of the probe, (c) at least one second temperature sensor located within the probe and parallel to the first sensor, (d) a thermal insulation member located between the first sensor and the second sensor (or sensors), (e) a data processing unit connected to the first and second temperature sensors calculating the body temperature according to heat flux measured between the body and the first sensor and between the first sensor and the second sensor (or sensors), and (f) a data display connected to the data processing unit.

Description

field of invention [0001] The present invention generally relates to a high speed accurate temperature measurement device, particularly for measuring the temperature of a low thermal conductivity cavity, hereinafter referred to as an "object", such as a human body. More specifically, the present invention relates to a high-speed accurate temperature measurement device, wherein based on the measured thermal Flux calculates object temperature. Background of the invention [0002] Each temperature measurement process involves transferring heat from the measured object to the measuring device probe. Heat transfer can occur in three ways; conduction, convection and radiation. In addition to measuring heat conduction (eg, in air or liquid flow), the method of the present invention can also measure heat convection. Bolometric measurements lack precision because achieving precision relies on prior knowledge of constants that are unknown to high reliability. [0003] Most tempera...
