| Zusammenfassung: | APPARATUS FOR MONITORING THE PRESENCE OF A PERSON IN A BED Apparatus for monitoring the presence of a person in a bed comprises a switching device and a monitoring device. The switching device comprises a flexible base member having an aperture therethrough, sandwiched between two conductive members and covered with two cover members. 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 comprises a binary signal generator, a time delay which produces a signal when the signal generator has been operated for a predetermined time, a latching device, an alarm signal generator and an alarm control device for varying the nature of the alarm signal produced by the generator. |
