DESC:1. Field of the Invention
The present invention relates to the field of nursing care and medical monitoring devices, particularly to a smart, wearable patch designed for real-time tracking of vital signs and prompt alert generation for nurses in clinical or home care settings.
2. Background of the Invention
Continuous monitoring of patients is essential in nursing care, especially in critical care, elderly care, and post-operative recovery. Traditional monitoring systems are often bulky, stationary, or dependent on manual observation. There is a lack of lightweight, wearable, and nurse-integrated systems that can provide real-time alerts and reduce nursing workload while improving patient safety.
3. Summary of the Invention
The Smart Nursing Assistant Patch comprises:
• A flexible, biocompatible patch embedded with sensors (heart rate, respiratory rate, temperature, SpO2).
• Bluetooth Low Energy (BLE) module for wireless data transmission.
• Microcontroller unit (MCU) for local processing.
• Rechargeable battery.
• Real-time alerting to the nurse’s mobile or workstation through a secure app/dashboard when vital thresholds are breached.
This system is particularly useful in multi-patient wards, home care, and post-discharge follow-up scenarios.

• Figure 2: Block diagram of the signal processing and communication flow.
• Figure 3: Placement of the patch on the patient’s chest.
• Figure 4: Nurse dashboard interface on tablet/mobile app.
5. Detailed Description of the Invention
The invention consists of a multi-layer patch integrating:
• Medical-grade adhesive hydrogel
• Sensors (ECG, PPG, thermistor)
• On-board power management
• BLE transmitter connected to a hospital Wi-Fi system/cloud database
• Nurse notification module (alerts via vibration, text, or sound)
• Data logging for post-event review and integration with EHR (electronic health records)
,CLAIMS:6. Claims (Provisional Application Format – Indicative Only)
1. A wearable patch system for continuous monitoring of patient vitals, configured to transmit data wirelessly to a nurse interface in real-time.
2. The patch of claim 1, wherein the sensors include ECG, temperature, and blood oxygen saturation sensors.
3. The system of claim 1, further comprising a nurse alert mechanism triggered when a preset threshold is breached.
7. Advantages of the Invention
• Portable and wearable for all age groups.
• Real-time alerts reduce the risk of clinical oversight.
• Can be used in both hospital and home care environments.
• Reduces nursing burden through automation and remote oversight.
• Supports better triage, early intervention, and patient outcomes.
