Abstract

PURPOSE:To secure the instantaneous transmission by forming the existing private telephone circuit via the signal branch insertion device in the form of the information transmission circuit within the hospital compound. CONSTITUTION:Sub-slave terminal unit 9 is connected to hospital terminal unit 8 via the signal branch insertion device plus private telephone circuits 11-1, 4-1, 10-1, 10-2, 4-2 and 11-2 respectively. Thus, various kinds of medical information within the hospital are monitored in a concentrated way and transmitted to central office device 6. In this way, existing 4-1 and 4-2 are utilized to carry out the communication.
