The infrared ray type clinical thermometer which has the heating possible infrared ray sensor and the infrared ray sensor

摘要

As for this invention, being the infrared ray sensor which electrically possesses the heating possible sensor housing, it has electric heating track structure (14) as the heating system which is attached to the ceramic baseplate with electric conduction type, it is controlled by the control control equipment the heating power according to need, it regards the infrared sensor. The ceramic baseplate (10) has the insulated ceramic material electrically, that electric insulated ceramic material for example, like the ceramics of alumina, aluminum nitride and beryllium oxide conveys heat well. The ceramic baseplate is good with any form according to need, but with the type which is separated with panel type simply, low from the fact that it is production possible, it seems like the octagon based surface in cost, the symmetrical based surface especially is desirable essentially. The ceramic baseplate (10) forms the bottom of the sensor housing, it is desirable at least to place one like the thermoelectric pile sensor (16) infrared ray sensor element. In addition, it has the electric strip conductor (12) which for the housing cover which for example corresponds (not to illustrate,) the contact area (12a) shows. Functioning it does the through hole contact (22), as an electric terminal area with above (10a) the ceramic baseplate (10) and bottom side. As for the electric heating track and the conductor (14 and 12), as the thick film track it is desirable to be actualized. The infrared ray sensor which relates to this invention especially is suitable for the measurement point of the infrared ray type clinical thermometer in order to measure the body temperature the inner ear.
