A probe cover for medical thermometer has a matching feature for preventing its use with an incompatible thermometer. A mechanical matching feature of the probe cover includes at least one of a fold, a step, or a series of holes or indentations that are respectively matched to a ridge, a valley or series of pins formed on the front end of a compatible thermometer. When applied to the compatible thermometer, the mechanical matching feature permits the probe cover to be fully seated on and retained by the probe, thereby placing the thermometer in condition for use. Alternatively, an opto-electronic matching feature of the probe cover includes a reflective layer for use with an opto-electronic detection circuit of a compatible thermometer. When applied to the compatible thermometer, the opto-electronic detection detects the reflective layer and places the compatible thermometer in an operational state for use.

A protective cover for an insertion probe of a medical instrument. The cover contains a flexible tubular body that compliments the probe geometry and a radially disposed flange that surrounds the proximal end of the body. A series of snap-on fasteners removably connect the cover to the instrument. A camming surface is located on the outer face of the flange which coacts with a cam follower that is movably mounted upon the instrument to flex the cover sufficiently to open the fastener and release the cover from the instrument and move the cover axially toward the distal end of the tip.

A box-packed ear thermometer probe cover capable of preventing contact infection comprises a packing box, a plurality of stacked ear thermometer probe covers, and a cover holder, wherein an opening which can be opened and closed is formed in the top of the packing box, a long slot is formed in a side face of the packing box, ear thermometer probe covers are placed in the packing box, each ear thermometer probe cover comprises a container structure and a container space, a cover holder is disposed below the lowest ear thermometer probe cover and comprises a sealing wall, a top surface and a suspension structure suspended on the top surface, the ear thermometer probe covers are supported by the cover holder, and the sealing wall extends upwards to the opening and seals the long slot.

An animal wellness notification system includes an attachment body configured to securely engage with an ear of the animal; an elongated temperature probe secured to the attachment body and configured to extend within the ear of the animal; a housing secured to the attachment body; a computer disposed within the housing and operably associated with the temperature probe; and a notification device in data communication with the computer, the notification device being configured to provide notice if a temperature of the animal goes beyond a determined threshold.
