A probe cover for covering a probe of a thermometer, the probe configured for receiving thermal energy indicative of a temperature, the probe comprising a proximal end in proximity to a housing of the thermometer and distal end, the probe cover comprising: a tip portion configured for covering the distal end of the probe; a base portion configured for retaining the probe cover at the proximal end of the probe; and a body portion disposed between the tip portion and the base portion, wherein: the tip portion, the body portion and the base portion are sequentially disposed in a direction along a longitudinal axis of the probe cover, and the base portion includes one or more matching features each configured to engage a corresponding feature of the thermometer housing for seating the probe cover on the probe, wherein the matching features include one or more recesses extending in a direction parallel to the longitudinal axis and wherein the housing includes corresponding projections extending in a direction parallel to the longitudinal direction; the base portion includes a brim extending laterally away from the longitudinal axis of the probe cover, the one or more recesses include one or more conical or similarly-shaped extensions formed on the brim and the one or more projections include one or more mating pins (22, 23) having conical or similarly-shaped features (22a, 23a) for effectively mating with the extensions; the thermometer having one or more ejectors (50a, 50b) positioned in the housing and being movably operable to extend from the housing and engage the bottom surface of the base portion for ejecting the probe cover from the probe; the probe cover being characterized in that each of the one or more ejectors is configured as a corresponding feature of the housing for mating with a respective one of the one or more matching features of the probe cover. a tip portion configured for covering the distal end of the probe; a base portion configured for retaining the probe cover at the proximal end of the probe; and a body portion disposed between the tip portion and the base portion, wherein: the tip portion, the body portion and the base portion are sequentially disposed in a direction along a longitudinal axis of the probe cover, and the base portion includes one or more matching features each configured to engage a corresponding feature of the thermometer housing for seating the probe cover on the probe, wherein the matching features include one or more recesses extending in a direction parallel to the longitudinal axis and wherein the housing includes corresponding projections extending in a direction parallel to the longitudinal direction; the base portion includes a brim extending laterally away from the longitudinal axis of the probe cover, the one or more recesses include one or more conical or similarly-shaped extensions formed on the brim and the one or more projections include one or more mating pins (22, 23) having conical or similarly-shaped features (22a, 23a) for effectively mating with the extensions; the thermometer having one or more ejectors (50a, 50b) positioned in the housing and being movably operable to extend from the housing and engage the bottom surface of the base portion for ejecting the probe cover from the probe; the probe cover being characterized in that each of the one or more ejectors is configured as a corresponding feature of the housing for mating with a respective one of the one or more matching features of the probe cover. the tip portion, the body portion and the base portion are sequentially disposed in a direction along a longitudinal axis of the probe cover, and the base portion includes one or more matching features each configured to engage a corresponding feature of the thermometer housing for seating the probe cover on the probe, wherein the matching features include one or more recesses extending in a direction parallel to the longitudinal axis and wherein the housing includes corresponding projections extending in a direction parallel to the longitudinal direction; the base portion includes a brim extending laterally away from the longitudinal axis of the probe cover, the one or more recesses include one or more conical or similarly-shaped extensions formed on the brim and the one or more projections include one or more mating pins (22, 23) having conical or similarly-shaped features (22a, 23a) for effectively mating with the extensions; the thermometer having one or more ejectors (50a, 50b) positioned in the housing and being movably operable to extend from the housing and engage the bottom surface of the base portion for ejecting the probe cover from the probe; the probe cover being characterized in that each of the one or more ejectors is configured as a corresponding feature of the housing for mating with a respective one of the one or more matching features of the probe cover.
