Ear-type thermometer and a control method thereof
First Claim
1. An ear-type thermometer having a probe formed with a probe opening at its tip which houses a temperature detection element which detects ambient temperature and an infrared detection element which detects infrared light emitted from a temperature measurement site within the aural cavity, and measures body temperature based on detection results from said two detection elements, the ear-type thermometer comprising:
- a probe cover which can be detachably provided onto said probe and covers said probe opening;
a detection means which detects attachment/detachment of said probe cover onto said probe; and
a correction means which corrects, based on the detection result of said detection means, body temperature which is measured based on detection results of said two detection elementswherein;
said correction means performs temperature correction which calculates correlation coefficient between detected temperature signal based on the detection results of said two detection elements and actual body temperature signal based on actual body temperature, andsaid correction means also performs temperature conversion using a first temperature conversion coefficient calculated by applying said temperature correction in a state without said probe cover and a second temperature conversion coefficient calculated by applying said temperature correction in a state with said probe cover.

Abstract
An ear-type thermometer which measures body temperature using a temperature detection element 21 that detects ambient temperature and an infrared detection element 22 that detects infrared radiation from a measurement site within the aural cavity, the 2 elements housed in a probe 3, wherein the ear-type thermometer comprises a probe cover 10 which can be detachably provided with the probe, a detection switch 60 which detects that the probe cover is attached or detached to the probe, and two temperature conversion coefficients 52a and 52b which corrects body temperature based on the detection result from the two detection elements. Further, the thermometer comprises a detection switch 60 which detects that the probe cover is attached or detached to and from the probe, a temperature conversion coefficient 52a which corrects body temperature based on detection results from the two detection elements, a control unit 50 which determines whether the probe cover has exceeded the usage count limit or not using an actual usage count, a speaker 12 or a liquid crystal display unit which alerts need to replace the probe cover when the usage count limit has been exceeded.

5. An ear-type thermometer having a probe formed with a probe opening at its tip which houses a temperature detection element which detects ambient temperature and an infrared detection element which detects infrared light emitted from a temperature measurement site within the aural cavity, and measures body temperature based on detection results from said two detection elements, comprising:
-
a probe cover which can be freely attached and detached onto and from said probe and covers said probe opening; a detection means which detects attachment/detachment of said probe cover onto said probe; a correction means which corrects, based on the detection result of said detection means, body temperature based on detection results of said two detection elements; a determination means which determines whether or not said probe cover has been used more than a usage count limitation based on the actual usage count; and an alert means or a display means for alerting need to replace said probe cover when the determination result from said determination means exceeds said usage count limitation wherein; said correction means performs temperature correction which calculates correlation coefficient between detected temperature signal based on the detection results of said two detection elements and actual body temperature signal based on actual body temperature, and said correction means also performs temperature conversion using a first temperature conversion coefficient calculated by applying said temperature correction in a state without said probe cover and a second temperature conversion coefficient calculated by applying said temperature correction in a state with said probe cover. - View Dependent Claims (6, 7, 8, 9)
