The patch type temperature measuring device 1 of the first preferred embodiment of the present invention is attached to the human body by the attaching/insulating layer 12. In a practical application, the patch type temperature measuring device 1 of the first preferred embodiment of the present invention is attached to the forehead of the subject by the attaching/insulating layer 12. The patch type temperature measuring device 1 of the present invention has a housing 10 adapted to be attached to the forehead of a subject, so that it is small in size and light in weight.

The main circuit board 14 is disposed within the housing 10. The controller 16 is soldered to the main circuit board 14. For ease of explanation, the components soldered to the main circuit board 14 are not fully shown. In a specific embodiment, the main circuit board 14 is preferably a flexible circuit board, but is not limited thereto.

The protective/thermally conductive cover 18 is fixed to the lower casing 104 and covered The first through hole 106 and the second through hole 122 are covered.

The horn 36 is soldered to the main circuit board 14 and electrically connected to the controller 16 and the battery 30, respectively. The controller 16 selectively outputs an alert signal to the speaker 36 according to the temperature signal. The horn 36 plays a sound according to the warning signal. For example, the controller 16 periodically controls the temperature measuring component 20 to measure the temperature of the human body, if the measured temperature exceeds a set fever temperature (eg, 38 ° C / 100.4 ° F), or a set temperature loss temperature (eg, 35 ° C / 95) At °F), the controller 16 outputs an alert signal to the horn 36. The speaker 36 dials the warning signal, that is, a beep is sounded to indicate a reminder. The subject's body temperature was originally the fever temperature, and the temperature has dropped to a safe temperature range for a while, or the fever has continued for a while, and the speaker 36 can also sound to notify others.
