Slide 1: Seconds matter. Yes, seconds actually do matter because when you are trying to save someone's life with CPR, every second matters. In education, there is always room for improvement. Aveen and I believe that CPR training can be improved, and that is what we focused on in our project.
Slide 2: Here you see a context image of a person conducting CPR. That person could very well be me because I am a certified CPR responder. For this, I understand the tremendous amount of pressure when one is trying to save another humans beings life. And from my CPR training, I know there is room for improvement and the possibility to save more lives.
Slide 3: This is what lead us to create SECONDS MATTER, a device that incorporates new methods of CPR education. The device focuses on both meditative training in the office as well as live feedback while a first responder is conducting CPR.
Slide 4: Here is one of my precedent images. Much of CPR training is comprised of dummy practice. When practicing, the cycle of CPR compressions is essential. Although we designed a totally different project than the CPR dummy, the basic principles of accuracy and rhythm were incorporated into our project.
Slide 5: This is another one of our precedent images. From this lung, we were inspired by the cycle of breath in addition to potentially adding a basic lung to our project.
Slide 6: Here is one of our original drawings. Our idea was a CPR glove that tracked your rate of compressions and either showed you your speed on a screen or through LEDs.
Slide 7: Here is an original design of our mechanical training device. Notice the lungs that go up and down with every breath and the slots for a ticker(every compression rate).
Slide 8: Our first prototype involved the moving lung.
Slide 9: We then expanded on this idea and added a mechanical hammer that would tick for every compression. To make the project more challenging, we decided that we would only use one motor and connect the moving lung and hammer with gears.
Slide 10: Our design changed entirely when we created the new big mechanical gear. This gear is powered by one motor, has ticking slots, and has a track for the lung to follow(up and down). We were going to connect it to the bottom through the lower track and wheels.
Slide 11: We made a big decision here and instead scraped the wheel design because it didn't work. We decided to connect the motor to the middle of the big gear and have the mechanical lung be off to one side.
Slide 12: Here is our iteration with the technology part of our project. I used an accelerometer and Arduino to program. Our idea here is that you can attach the circular interface to a wrist band and put the Arduino in a pocket. LEDs will shine indicating your compression speed.
