Monitoring IV fluid bag ranges with the Arduino Portenta H7 and Imaginative and prescient Protect
June twenty second, 2022—
When a affected person is receiving intravenous (IV) fluids, it’s important that air shouldn’t be launched into the road, as its presence can create points reminiscent of extreme strain and even embolisms that may be life-threatening. Usually, the extent of fluids remaining throughout the bag is periodically checked by a nurse, however as a consequence of challenges associated to staffing, this won’t be sufficient. Subsequently, Manivannan Sivan devised an automatic monitoring system that makes use of laptop imaginative and prescient together with machine studying to do that repetitive job as a substitute of an individual.
To start the undertaking, Sivan gathered a sequence of photos that spanned three classes with an Arduino Portenta H7 and Imaginative and prescient Protect. Inside every image, the IV fluid bag is 15cm away and incorporates both an ample, lower than 50%, or low stage of fluid remaining. As soon as skilled, his mannequin was capable of efficiently acknowledge the right stage round 96% of the time, though extra photos taken at totally different mild ranges would assist enhance the accuracy much more.
From right here, Sivan deployed his mannequin again to the Portenta H7 to see the way it performs in day-to-day situations, with classification going down as soon as each two seconds. His plan is to take the ensuing class and export it to an awaiting server over the community in order that hospital workers can see the fluid bag’s standing in real-time on a dashboard.
