Emergency safety system for university hospital operating rooms with self-powered emergency bells (Myongji Hospital) · Field Cases

Site: Myongji Hospital

Self-powered emergency bells were installed in the operating rooms so that an emergency call reaches the office and control room immediately, without wiring or batteries.

1. Purpose

A power-free emergency safety management system using self-powered sensors.
The hospital did not have an adequate system for emergencies and safety management.
An emergency response measure was needed for the operating room area.
An emergency alarm system to the office and control room was needed for emergencies.
Adding signal repeaters extends the transmission range of the self-powered sensors.

2. Benefits

Emergency and safety prevention system installed at Myongji Hospital: urgent emergency call signals are sent from the operating rooms so staff can check and respond.
Extended wireless range: emergency signals are extended through repeaters, giving a detection range of 1 km or more in open field (emergency detection in a wide range of spaces).
Can be extended to other hospitals and managed facilities.

3. System configuration

Emergency detection — A wireless emergency signal is sent from inside the operating room
Repeater — Receives the emergency signal and extends the range (150 m)
Single-window Monitor (receiver) — Emergency alarm that shows a unique number for each signal
