Documentation: Patient Medical Emergency Alert System (PMEAS)

Overview

The Medical Emergency Alert System is a project designed to provide a quick and reliable method for individuals to send emergency alerts in medical situations. The system utilizes a GSM module to send an SMS and make a call to a predefined emergency contact when a button is pressed. This documentation provides an overview of the system, its components, and its real-life use case.

Components

The Medical Emergency Alert System consists of the following components:

  1. Microcontroller (Arduino or compatible board): The brain of the system that controls the operations and interactions with other components.
  2. GSM Module (SIM900A): A module that allows communication over the GSM network, enabling SMS sending and call making functionalities.
  3. Button: A physical button that acts as the trigger for sending emergency alerts.
  4. LEDs (Light-Emitting Diodes): Visual indicators that provide feedback to the user about the system's status.
  5. Buzzers: Audio indicators that produce sound alerts to attract attention.

Real-Life Use Case

The Medical Emergency Alert System is designed to be used in scenarios where immediate medical assistance is required. Here is an example of a real-life use case for this system:

  1. Patient with a Medical Condition: Consider a scenario where an individual, such as an elderly person or someone with a chronic medical condition, requires regular medical assistance or monitoring due to their health condition.

  2. Emergency Alert System Setup: The Medical Emergency Alert System is set up in the individual's home or living space. The GSM module is connected to the microcontroller, and the button, LEDs, and buzzers are appropriately connected.

  3. Emergency Button Pressed: In the event of a medical emergency, the individual can press the button on the Medical Emergency Alert System. When the button is pressed, the system detects the button press and initiates the emergency alert process.

  4. Emergency Alert Triggered: The system responds to the button press by activating the LEDs and buzzers to attract attention. The LEDs provide visual indications, while the buzzers emit audible alerts, ensuring that the emergency situation is noticed by people nearby.

  5. SMS and Call Initiation: If the button is held for more than 10 seconds, indicating a genuine emergency, the system proceeds to send an SMS and make a call to a predefined emergency contact. The SMS contains a predefined message indicating a medical emergency, while the call ensures immediate communication with the emergency contact.

  6. Emergency Contact Notification: The SMS is sent to the emergency contact's mobile number, notifying them about the medical emergency. Additionally, the system initiates a call to establish direct communication. The emergency contact can receive the SMS and answer the call to assess the situation and take appropriate action.

  7. Emergency Response: Upon receiving the SMS and answering the call, the emergency contact can respond to the medical emergency by contacting emergency medical services, arranging immediate assistance, or providing necessary guidance to the individual in distress.

  8. Alert System Reset: Once the emergency alert has been triggered, the system resets itself. The LEDs and buzzers are deactivated, and the system is ready to detect future emergency button presses.

Advantages and Benefits

The Medical Emergency Alert System offers several advantages and benefits, including:

  1. Quick Emergency Communication: The system enables rapid communication of medical emergencies to a designated emergency contact, ensuring that help can be summoned promptly.

  2. Reliability and Simplicity: The system is designed to be reliable and straightforward, allowing individuals with limited technical knowledge to use it effectively during critical situations.

  3. Immediate Awareness: The LEDs and buzzers provide immediate visual and auditory alerts, attracting attention and notifying people nearby about the ongoing medical emergency.

  4. Flexibility: The system can be customized to fit specific needs

. Emergency contact numbers, message content, and other parameters can be adjusted according to individual requirements.

  1. Cost-Effective Solution: Compared to dedicated medical alert systems, the Medical Emergency Alert System provides a cost-effective alternative while maintaining essential functionalities.

Conclusion

The Medical Emergency Alert System offers a simple yet effective solution for individuals requiring immediate medical assistance. By incorporating a GSM module, the system enables the sending of SMS alerts and making of calls to emergency contacts. With its user-friendly design and reliable operation, the system serves as a valuable tool for medical emergency situations, ensuring prompt response and potentially saving lives.
