Nurse Calling System With Wrist-Watch

System Components

1. Patient Call Unit (Button/Panel)

   • Installed near beds or bathrooms.

   • Patients press a button in case of need or emergency.

2. Wrist-Watch Receiver for Nurses

   • Worn by nurses/caregivers.

   • Displays the room/bed number of the patient calling.

   • May include vibration or sound alerts for attention.

3. Central Control Unit / Server (optional)

   • Logs calls.

   • Assigns alerts to nurses based on availability or ward location.

   • Allows management to monitor response times.

4. Wireless Communication Protocol

   • Wi-Fi, Zigbee, LoRa, or RF technology for transmission between devices.

Working Principle

1. Patient presses the call button.

2. Signal is wirelessly transmitted to the nurses wristwatch.

3. Wristwatch displays details like:

   • Patient ID / Room Number

   • Time of call

   • Priority level (optional)

4. Nurse acknowledges the call via the watch (in advanced systems), and attends to the patient.

5. Call status is updated (attended, pending, escalated) on central unit.

Key Features

• Real-time alerts and notifications.

• Hands-free and mobilenurses stay responsive even while moving.

• Reduced patient wait time and improved safety.

• Quiet operation (vibration mode) reduces noise pollution.

• Logs and analytics for performance tracking (if integrated with a server).

Optional Features

• Two-way communication (voice or text).

• Fall detection sensors integrated with the wristwatch or wearable.

• Emergency escalation if the first responder does not acknowledge in a set time.

• Integration with hospital management system (HMS).

Use Cases

• Hospitals with large wards.

• Elderly care facilities.

• Rehabilitation centers.

• Maternity and ICU wards.
