Inspiration
Wound dressing and bandages/casts speed up the time of recovery by around 30-70% – it is easy to use, cost-effective, and extremely accessible. The bandage/cast must be taken off to reapply the dressing, exposing the wound to potential contamination. It is inconvenient for the patient and might need a healthcare professional to re-do the bandage or cast. Introducing Wounds? Addressed, a wearable that autonomously delivers dressing to the wound inside the bandage.
What it does
Detects the temperature of the skin surrounding the wound inside the bandage and reapplies dressing as it’s being used up in the healing process.
How we built it
BMP280 + AHT22 humidity, temperature, and pressure sensor connected to the Arduino which makes the 28BYJ-48 step motor spins to eject ointment into the wound.
Challenges we ran into
- We originally wanted to use humidity as a metric but there was a lack of research on humidity in wounds and bandages.
- The wound is constantly covered and unable to dry to a degree detectable by the sensor
- Finding a creative mechanism to dispense the ointment directly into the wound while maintaining an ergonomic layout on the patient
Accomplishments that we're proud of
- Learning Arduino from scratch
- Framing a creative problem and developing a unique solution
What we learned
Arduino programming, creative use of sensors and materials.
What's next for Wounds? AdDRESSED.
- Sleeker design with a better enclosure
- Use better sensors and tech
- More data analysis programmed to the injury
- Alert user when dispensing will begin
