Abstract: The invention is a device for use as a prop to hold the mouth open which consists essentially of a bite block with an elongated portion that is deflected to provide a turn of about 180.degree. so that the elongated portion extends around the outside of the cheek with the end of the extension pointing backward from the mouth to form a handle by which the bite block is held in position.

Abstract: A cleaning apparatus is contained within the potable water collection apparatus, to selectively clean the cooling coil and the collection pan, when the collection apparatus is not collecting potable water. The potable water collection apparatus comprises an enclosure having an air mover to provide a dynamic airflow path between an inlet port and an outlet port; a compressor; a condensing coil in fluid communication with the compressor; a cooling coil in fluid communication with the condensing coil, thus forming a closed loop circulation system for the circulation of a refrigerant fluid. The cooling coil is in the dynamic airflow path. A collection tray is disposed below the cooling coil, and a collection container receives collected water from the collection tray. The cleaning apparatus comprises a hood enclosure for substantially enclosing the cooling coil and the inner surface of the collection tray. The hood enclosure is movable between a first closed cleaning position and a second opened position.
