ABSTRACT:
An integral mouth-piece has a flexible nipple portion and a stop ring flange portion and is used in a combined electronic clinical thermometer and pacifier which easily and safely takes the temperature of either an infant or a small child. The combined electronic clinical thermometer and pacifier includes a housing, a temperature sensitive element, a circuit board, a temperature oscillating circuit, a body temperature measuring circuit and a digital display device. The housing has a front face and is mechanically coupled to the stop ring flange portion. The temperature sensitive element has a transducer and a pair of wire leads. The transducer is disposed in the flexible nipple portion of the integral mouth-piece. When the flexible nipple portion is inserted into the mouth the transducer detects a body temperature. The circuit board is disposed within the housing. The temperature oscillating circuit is electrically coupled to the pair of wire leads of the temperature sensitive element and is disposed on the circuit board. The body temperature measuring circuit is electrically coupled to the temperature oscillating circuit and is disposed on the circuit board. The digital display device is electrically coupled to the body temperature measuring circuit and is disposed on the circuit board. The flexible nipple portion of the integral mouth-piece has an outer sidewall and an inner sidewall with a recessed area in order to allow the transducer, which is disposed adjacent to said recessed area, to be as close to the outer sidewall as possible.
