PURPOSE:To ensure the secrecy of a telephone call by connecting patients to a nurse station directly by providing a master equipment to the nurse station and a subordinate equipment as a calling means to every patient. CONSTITUTION:A patient, when he calls a nurse station, operates the indicating means 23 of a subordinate equipment 3. For example, when an indicating means 231 is operated, a displaying means 241 makes a lighting display and a selection part 21 performs selecting operation, which is detected by a detection part 25. This operation is detected by a detection part 15 on a master equipment side and a displaying means 121 is selected by a selection part 11 to perform diaplay by lighting. Consequently, the nurse station knows calling from the patient which corresponds to the displaying means 121. In this state, an indicating means 131 is operated at the nurse station for a telephone call with the patient. This is selected and detected by the selection part 11 and horn control parts 17 and and 27 are put in operation. Consequently a selection part 21 selects a horn 221, which is connected to a horn 18 on the nurse station side. |
