Abstract
A system for fall prevention includes a platform for supporting a patient, the platform including rails and rail sensors, an image capturing device for capturing images of the patient, a patient monitor for interactive communication with the patient, a health monitoring station for receiving rail sensor data and communicating with the patient monitor, and an edge network device co-located with the platform and communicating with the station and the image capturing device. The edge network device receives image data from the image capturing device when the rail sensors indicate that the rail is down and the patient is at risk to themselves, anonymizes the image data to generate a skeleton image, determines a posture associated with the skeleton image, triggers alerts at the station when the patient is predicted to be sitting, and triggers escalated alerts at the station when the patient is predicted to be standing.
