A group of college students has developed a series of devices for a Michigan-based company that addresses a common problem for healthcare workers: keeping hands sanitized and clean.
…
“Every day, about 250 people across the country die from hospital infections, and over half of infections are caused by direct contact,” said Sterilogy president Hal Zaima in a prepared statement. “It results in more than $30 billion in unnecessary costs to hospitals.”
The students based their system on an idea from Sterilogy co-founder Bradley Ahlgren, an orthopedic surgeon who found wall-mounted sanitizers inconvenient and often empty. Ahlgren started carrying around canisters of sanitizers in his scrubs.
Zaima enlisted the help of aMDI in spring 2017 to design, build and test a series of prototypes for the hand hygiene system, which includes three separate devices. The personal sanitizer unit (PSU) is a body-worn device that dispenses the foam sanitizer; the zone alert emitter unit is attached to a patient’s bed and communicates with the PSU to remind healthcare workers to sanitize; and the base station unit is placed at a central location, like a nurse’s station, and uploads data from PSUs when they are in close range.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
