Appoint

Appoint is a system of IoT devices to make it easy to arrange medical appointments.

Batteries Included

• next-dashboard/ Next.js-powered dashboard and backend
• nfc-backend/ NFC reader backend code on the RPI with python, connects with PN532 via i2c
• flutter-app/ Flutter-powered mobile app to create appointments and emit NFC signals
• schedule-stream/ A simple express server that serves a Socket.IO endpoint to be used to notify subscribers of schedule change
• time-faker/ A simple express server that acts as a time provider that can be offsetted for testing

Dashboard Screenshots

Flow

• Patients registers an account through the flutter app
• Creates a new appointment
• Pick an empty schedule
• Patient physically arrive at the appointed location a few minutes before the scheduled time
• Patient scans their phone on an NFC reader provided in the physical location
• Patient waits until the doctor starts the appointment
• Patient gets into a room with the doctor

The Architecture

Here's an overview of the components used (excluding time-faker)

    A(Patient Phone) <-- API Calls --> B(Backend Server)
    B -- HTTP Requests --> C(Schedule Stream)
    D(NFC Reader) -- HTTP POST Request --> B
    E(User Frontend) -- HTTP Requests --> B
    A -- NFC --> D
    C -- Websocket (Socket.IO) --> A
    C -- Websocket (Socket.IO) --> E

    Patient->>Backend: Register and Login (API Call)

    Backend->>ScheduleStream: Update New Appointment (HTTP Request)
    ScheduleStream->>Dashboard: Realtime Update on New Appointment
    ScheduleStream->>Patient: Realtime Update on New Appointment
    Patient->>Backend: Request Check-In ID (15 mins before appointment)
    Backend->>Patient: Provide Check-In ID
    Patient->>Patient: Tell user to tap on the NFC reader
    Patient->>NFCReader: Taps NFC and sends Check-In ID
    NFCReader->>Backend: Notify Check-In (HTTP POST)
    Backend->>ScheduleStream: Update Check-In Status (HTTP Request)
    ScheduleStream->>Dashboard: Realtime Update on Check-In
    ScheduleStream->>Patient: Realtime Update on Check-In
    Patient->>Patient: Tell user that check-in is successful
    Dashboard->>Backend: Update Appointment to "In-progress" (API Call)
    Backend->>ScheduleStream: Update Appointment Status (HTTP Request)
    ScheduleStream->>Dashboard: Realtime Update on Appointment Status
    ScheduleStream->>Patient: Realtime Update on Appointment Status
    Patient->>Patient: Tell user to enter the room
    Dashboard->>Backend: Update Appointment to "Finished" (API Call)
    Backend->>ScheduleStream: Update Appointment Status (HTTP Request)
    ScheduleStream->>Dashboard: Realtime Update on Appointment Status
    ScheduleStream->>Patient: Realtime Update on Appointment Status
