In the U.S., by late 2017, owing to the statistics of opioid addiction it was declared as a national public health emergency.
To serve opioid addiction, a team of software engineering students at Carnegie Mellon University have developed a wristband. The device can detect opioid overdose and raise an alarm and message to contacts of the user in a state of emergency. HopeBand, as the wristband has been aptly named, can serve to be a tool of hope in the instance of opiate overdose.
HopeBand gauges User’s Oxygen level to raise alert
Physically, HopeBand is a pulse oximetry device worn on the wrist. Regarding its functionality, it only needs to be paired with the user’s smartphone, explained an associate involved in the project. In the event of an overdose, it raises an alert for emergency contacts.
Further, the functionality of gauging signs of distress is another feature of the device, explained another associate involved in the development. The pulse oximetry sensors of the device can monitor oxygen levels in blood. It does so by giving out light from LEDs through the skin and noticing changes in light absorption. In the event of drop of oxygen to low level signaling overdose, the device monitors the user for 10 seconds before an alert is raised.
Further elaborating on the working of the device, the device’s sensor takes numerous readings on an ongoing basis when paired to a smartphone via Bluetooth. This is to establish a baseline reading.
