Wearable device may stop opioid overdoses before they start — via healthing_ca

Dave Yasvinski,Doctors waging war on the opioid crisis may soon have a new weapon in their arsenal: a wearable device that detects and reverses the effects of an overdose by automatically administering life-saving medication.

“The opioid epidemic has become worse during the pandemic and has continued to be a major public health crisis,”, lead author of the study and a UW doctoral student in the Paul G. Allen School of Computer Science and Engineering. “We have created algorithms that run on a wearable injector to detect when the wearer stops breathing and automatically inject naloxone.”

The system measures respiration using a pair of accelerometers and contains an onboard processor that activates a naloxone injector if it determines breathing has stopped. The device, which has been granted regulatory approval in the U.S., can also share breathing data with mobile devices via Bluetooth.

Naloxone was only used during the hospital trial, where volunteers were instructed to breathe normally before holding their breath for 15 seconds to simulate the type of apneic event typically indicative of an overdose. Subjects who did not move for the 15-second period were injected with naloxone by the device and subsequent blood tests revealed the amount would have been sufficient to reverse an overdose had there been one.
