Abstract: In order to monitor the movements of a patient who is confined to a bed and to alert supervisory personnel in the event that the patient attempts an unauthorized departure therefrom, an array of radiant energy emitters and a corresponding array of radiant energy detectors are installed in the headboard and in the footboard of the bed. In one embodiment, emitters supply infrared energy to the detectors so as to cover the bed with a blanket of invisible light. When the transmission of infrared energy is interrupted for a predetermined time by an overactive patient, both local and remote warning signals are generated to immediately alert the supervisory personnel to the possibility of impending patient injury.

Abstract: A unitary body has an elongated lower portion with a fluid discharge passageway and an upper portion which has continuous sealing walls. Each side wall fits between a labia minora and a spread labia majora. The front wall is disposed slightly forward of the preputium clitoridis and the rear wall is disposed slightly forward of the pars intermedia. Side walls are concavely curved to generally match but somewhat distort abutted flesh. Flanges intermediate lower and upper portions form a resting surface for a pair of the user's phalanges in pressing the body into place.
