Title:
CLINICAL THERMOMETER
Document Type and Number:
Japanese Patent JPH04299225
Kind Code:
A
Abstract:
PURPOSE:To enable accurate measurement of a body temperature in a short time by providing an infrared sensor and a temperature correcting element and by computing and displaying detection outputs of the infrared sensor and the temperature correcting element. CONSTITUTION:Inside a casing 11, an IC chip containing various electronic circuits are disposed together with an electric cell. A detecting unit 7 is provided in the fore end part of a narrow part 11a of the casing 11 and infrared radiation from a human body is made to enter the detecting unit 7 through a window 15 formed of an infrared transmitting material such as germanium(Ge). Inside the detecting unit 7, an infrared sensor 18 having a thermopile in a base 16 and also a temperature correcting element 19 are provided. Detection outputs of the sensor 18 and the element 19 are computed in the electronic circuits in the casing 11 and the result of computation is displayed. In this way, a body temperature can be measured accurately in a short time.
