Wireless Nurse-call System

I&T Wish Wireless Nurse-call System
(REF : W-0291)
Summary and Challenges This project aims to develop and apply wireless nurse-call system to replace the conventional nurse-call system in hospitals, with advantage of prompt deployment and negligible impact to ward operation during system installation and testing.
Expected Outcome
  • Durable tactile feel wireless nurse call unit completed with a nurse call push button, an emergency call pull button, a reset button and a built-in wireless transceiver based on an open wireless communication protocol, complying with Health Technical Memorandum (HTM) 08-03 or Underwriters Laboratories (UL) 1069.
  • Central display console which connects with system components through wireless data communication network is capable of displaying the real-time status of the nurse call units and the fault alarm in a Graphical User Interface (GUI) and logging key performance data for effective operation and maintenance management at the nurse station.
  • System should incorporate the following functions:
    • To attain an average system availability level of 99.5%, the miss call rate due to radio frequency interference and the call response time can be minimized by setting a time limit for call re-transmission, typically, in unit of seconds;
    • To set a processing time limit of 5 minutes for the system–initiated fault diagnostic routine for facilitating early automatic fault detection of system wireless components and early notification to maintenance agent. A typical setting of the transmission interval of the health-check signal for fault detection of wireless nurse call units and wireless hubs is 1 minute;
    • Automatic fault detection includes but not limited to ‘low battery’, ‘out-of-range’ and ‘out-of-battery’ of wireless nurse call units;
    • Reassurance light and sounder to indicate the activation of wireless nurse call units, complying to HTM 08-03;
    • Wireless nurse call units can be easily taken down from a lockable bracket for patients’ remote use;
    • Central display consoles can extend to wireless phones and pagers for maximum mobility (optional);
    • Extra provision of remote nurse call button or wrist/ neck pendant which allow patients to make a call from any locations in the concerned wards (optional).
Expected Trial Duration 9 months
