The present invention provides a probe cover for an ear thermometer and a manufacturing method thereof. The probe cover is for sheathing a measuring probe of the ear thermometer, and an engaging means is provided at a bottom of the measuring probe. The probe cover comprises a main body of a hollow structure, an abutting segment and a base. Therein, the main body has an open end and a closed end opposite to the open end. An assembling direction extending from the open end toward the closed end is where the measuring probe is assembled along. Further, the main body has a diameter gradually reducing along the assembling direction. The closed end allows infrared rays to be received by the measuring probe to pass therethrough. Therein, the abutting segment is provided at the open end of the main body, and the base is annularly provided around a periphery of the abutting segment. The probe cover is characterized in being integrally formed, and having an annular shoulder provided at the abutting segment for accommodating the engaging means of the ear thermometer, as well as a plurality of separated protuberances, which are formed inwardly at a combining portion between the abutting segment and the base, for being engaged with the engaging means of the ear thermometer so that the probe cover can be firmly engaged with the measuring probe.

The present invention discloses a probe assembly for used in an infrared ear thermometer. Given that the exchanged thermal radiation and the infrared detector's temperature are known, the subject temperature can be calculated according to Stefan-Boltzman's law. To make the Stefan-Boltzman's law applicable in a dynamic environment where temperature may vary greatly, the contact temperature sensor (thermistor) must acuurately and fast track the temperature of the infrared detector (thermopile sensor). By using the heat transfer theorem, the disclosed assembly makes the thermistor accurately track the cold junction temperature of the thermopile chip without being in an isothermal condition. Not only minimizes the measurement error in a dynamic environment, the design of the disclosed probe assembly also makes a samll and compact infrared thermometer possible.

An ear thermometer which includes a temperature detection element and infrared detection element arranged near the opening portion of a probe achieves a reduction in manufacturing cost while reducing the influence of thermal shock. This invention provides an ear thermometer incorporating, in a probe, a temperature detection element to detect an environmental temperature and an infrared detection element to detect infrared radiation emitted from a temperature measurement region in an earhole. The probe includes an end face portion having an opening in its distal end, an inner surface portion of a hollow cylindrical member, and an inwardly protruding engaging portion. A detection element housing is fixed to close the opening of the probe and to form an air layer between the detection element housing and the probe.

A multiple measurement memory-type electronic thermometer includes an ear temperature measuring unit, a microprocessor, a keypad unit, a display unit, and a memory unit. The ear temperature measuring unit, the display unit, and the memory unit are controlled by the microprocessor. When the activation key of the keypad unit is pressed by the user, being controlled by the microprocessor, the ear temperature unit is activated to perform measurement. The measuring result of the ear temperature unit is sent back to the microprocessor, displayed by the display unit, and saved in the memory unit. The memory unit is partitioned into a plurality of independent memory sectors. Each sector includes a queue data structure, such that the ear temperature measured from each person and the measuring time can be stored in the corresponding memory sector. Therefore, measurement of multiple people can be performed, memorized and retrieved.

An ear thermometer including a main body and a probe secured thereto for receiving heat radiation emitted from ear canal. A disposable sheath is operative to surround the probe and isolate the probe from contact with the ear canal. A non-detachable cap which is secured to the main body and the probe are movable relative to each other, thereby allowing the disposable sheath to be popped off of the probe by movement of the non-detachable cap or the probe.
