Zusammenfassung:	Apparatus for monitoring the presence of a person in a bed comprises a switching device (10) and a monitoring device (110). The switching device (10) comprises a flexible base member (12) having an aperture (22) therethrough, sandwiched between two conductive members (28, 34) and covered with two cover members (36, 40). When a patient lies on the switching device, the base member is deformed allowing the two conductive members to close the circuit. The monitoring device (110) comprises a binary signal generator (112), a time delay (124) which produces a signal when the signal generator has been operated for a predetermined time, a latching device (130), an alarm signal generator (142) and an alarm control device (132) for varying the nature of the alarm signal produced by the generator.
