By incorporating the local control station 22 in the cot of the infant 10, a radio communication link can be established between the components (12, 14) of the child station and the local control station 22. The control station 22 can then be used to receive data from the monitors and sensors forming part of the child station to monitor data such as heart rate, breathing and the integrity of the system.

  • the most obvious alarm condition is constituted by an abnormal increase in the distance between the local control station and either or both of the umbilical stump monitor 12 and the infant's armband monitor 14 such as might arise when the infant 10 is removed from her cot or the vicinity of the mother (the vicinity of the local control station 22) without authorisation.
  • the umbilical stump monitor 12 and the infant's armband monitor 14 could also be programmed to signal an alarm condition should there be any attempt at detaching either or both of the two monitors, 12 or 14 from the infant 10. If the umbilical stump monitor 12 and the infant's armband monitor 14 should become separated from one another by more than a predetermined distance, this could, in itself, constitute an alarm condition.
  • All of these alarm signals can be created with the use of fixed range transceivers and circuitry adapted to poll the transceivers periodically and to output an out-of- range signal whenever a transceiver poll yields a negative result or a weak signal result.
  • the local control station 22 can be programmed to raise an alarm on receipt of an alarm signal output by one or more of the vital signs sensors incorporated in the umbilical stump monitor 12 or the infant's armband 14. By programming the local control station 22 to read the cessation of the infant's breathing or heartbeat as alarm conditions, the local control station acts as an apnoea or heart arrest monitor.
  • the system may include vicinity monitors, such as door post monitors, that are adapted to raise an alarm upon the unauthorised movement of any one of the umbilical stump monitor 12, the infant's armband monitor 14 or the local control station 22 through a monitored doorpost.

  • Another level of security could be added by programming the system to ensure that the mother always accompanies the infant through a monitored doorpost. This can be done by requiring the simultaneous detection of both the mother's armband 16 and one or both of the umbilical stump monitor 12 and the infant's armband 14 by the door post monitor. If only one of these items passes a doorpost monitor unaccompanied by the other, an alarm will be raised.

L'association peut être établie en fournissant des séquences de données codées appariées, avec assistance dans la surveillance vis-à-vis de tout mauvais appariement de la mère et du nourrisson (10), une fois que la naissance a eu lieu. Dans une forme d'exécution préférée, une alarme est déclenchée dans le cas où les postes mère et enfant (14, 16) sont séparés au-delà d'une distance prédéterminée. L'invention concerne également un poste de surveillance local (22) et un poste de surveillance central (24) susceptibles de communiquer avec le système.
