Monitoring IV fluid bag ranges with the Arduino Portenta H7 and Imaginative and prescient Defend

When a affected person is receiving intravenous (IV) fluids, it’s vital that air is just not launched into the road, as its presence can create points resembling 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 attributable to challenges associated to staffing, this may not be sufficient. Due to this fact, Manivannan Sivan devised an automatic monitoring system that makes use of pc imaginative and prescient together with machine studying to do that repetitive job as an alternative of an individual.

To start the venture, Sivan gathered a collection of photos that spanned three classes with an Arduino Portenta H7 and Imaginative and prescient Defend. Inside every image, the IV fluid bag is 15cm away and incorporates both an satisfactory, lower than 50%, or low stage of fluid remaining. As soon as skilled, his mannequin was in a position to efficiently acknowledge the right stage round 96% of the time, though extra photos taken at completely different gentle 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.
