DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Reference is now made to Fig. 1 which illustrates an ear temperature measuring device 10 constructed and operative in accordance with a preferred embodiment of the present invention.
Device 10 includes a flexible probe 12 insertable into an external acoustic meatus 14 of an ear 16. Flexible probe 12 may be constructed of an elastomeric material, such as rubber or neoprene, or a flexible plastic. A temperature sensor 18 is disposed in flexible probe 12 and is adapted for measuring a temperature of ear 16. Temperature sensor 18 may be any kind of temperature probe, such as a thermistor, a thermocouple, or a radiative temperature sensing element. Most preferably temperature sensor 18 is a thermistor and may be either a negative temperature coefficient thermistor or a positive temperature coefficient thermistor.
Flexible probe 12 extends from a housing 20 which includes a visual temperature display 22 faced opposite to a distal end 24 of probe 12.
An air pump 26 is in fluid communication with flexible probe 12. Specifically, in accordance with a preferred embodiment of the present invention, air pump 26 includes a push button 28 located on housing 20 which pumps air to probe 12 via one or more inlet holes 30 formed in housing 20 and/or push button 28. Fig. 1 shows flexible probe 12 inflated by air pump 26 such that temperature sensor 18 is moved towards the inner surface of external acoustic meatus 14 such that accurate temperature readings may be made. This may be particularly important for a thermistor-type of sensor which measures the temperature by heat conduction.
In accordance with a preferred embodiment of the present invention, ear temperature measuring device 10 includes a voiced annunciator 32 for audibly annunciating a temperature measured by sensor 18.
In order to provide entertainment to a person while measuring his/her temperature, a music generating device 34 is disposed in housing 20, or alternatively in flexible probe 12. Music generated by music generating device 34 may be transmitted via holes 36 formed at distal end 24 of probe 12. Preferably control apparatus 38 is provided, such as a chip comprising control circuitry, which is in electrical communication with sensor '18 and music generating device 34. Control apparatus 38 controls operation of music generating device 34 such that device 34 automatically starts playing music before sensor 18 is optionally positioned to measure a temperature of ear 16 and stops playing music when sensor 18 has sensed a generally steady- state temperature of ear 16. In accordance with a preferred embodiment of the present invention, ear temperature measuring device 10 includes a sphygmometer 40 disposed in flexible probe 12 and adapted for measuring a pulse of ear 16.
Data logging apparatus 42 may be provided in wired or wireless communication with sensor 18 for logging temperature data. Reference is now made to Fig. 2 which illustrates that ear temperature measuring device 10 may be provided with a disposable cover 44 for covering and protecting probe 12. Cover 44 may snap on to the body of housing 20. It is noted that device 10 is shown deflated in Fig. 2. An on/off button 45 may be provided on housing 20.
Ear temperature measuring device 10 may be conveniently worn by a user in a variety of manners. For example, Fig. 3 illustrates device 10 with earphones 46, whereas Fig. 4 illustrates device 10 with an earpiece 48.
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the features described hereinabove as well as modifications and variations thereof which would occur to a person of skill in the art upon reading the foregoing description and which are not in the prior art.
