Abstract: A device consisting in a combination of a pacifying nipple and a mouth thermometer and particularly constructed to enclose the thermometer and avoid breakage thereof and to allow easy disassembly. This combined pacifying nipple and mouth thermometer device comprises a thermometer tube forming a temperature display main portion and a liquid bulb portion at one end of the main portion, an elastic protection sleeve tightly engages over the thermometer tube near said one end thereof, a pacifying nipple defining a mouthpiece portion and a lip abutment flange, the mouthpiece portion being engaged over the elastic protection sleeve, and having an annular external bead, the abutment flange being clamped against the annular bead, and a transparent tubular cover removably engaging over the temperature display portion and releasably secured to the lip abutment flange.

Abstract: A mouth thermometer combined with a pacifier in the form of a nipple to take the temperature of a young child or baby in the mouth thereof, instead of in the rectum, as commonly done so far, while averting the drawbacks inherent to the use of the conventional thermometer for so doing. The combination thermometer including a mercury thermometer tube defining a mercury bulb portion and a temperature display portion, a shield surrounding the bulb portion, a flexible nipple mouth-piece surrounding the shield and the bulb portion therein, and a stop ring integrally formed with the nipple mouth-piece and retained at the junction of the thermometer tube portions by an annular bulge of the shield.
