To provide a system which allows a medical worker to visit properly to a sickroom of a patient even if the patient does not call, thereby providing the patient with satisfactory care.

A call signal is input to work a timer 13. When no call signal is input, even if the timer 13 shows a determined time to a patient, and when it is decided by care plan information that the patient stays in a sickroom, a notice using an imitative call signal is made by a parent machine controller 11 to reset the timer 13, while when it is decided that the patient does not stay there, no notice is made to reset the timer 13. Consequently, even if the patient does not call a medical worker, and when the patient stays in the sickroom, a medical worker receives an imitative call to visit the sickroom and can provide the patient with satisfactory care, while when a patient does not stay there, a medical worker receives no imitative call and may not visit the room.
