Ocamar Based on multi-mode communication technologies including LF, BLE Bluetooth and RFID, the Ocamar Intelligent Hand Hygiene Compliance Management System is composed of staff location badges, touch/press hand sanitizer sensors, wireless gateways and intelligent management platform. In line with WHO’s Five Moments for Hand Hygiene, the system automatically captures hand disinfection behaviors via short-distance induction between staff badges and sanitizer dispensers, replacing error-prone manual spot-check statistics. It monitors sanitizer residue in real time with low-stock alerts and auto-generates compliance reports by individual or department accessible across multiple terminals. Featuring wiring-free quick installation, the staff badges can be expanded for contact tracing and emergency call functions. Sharing the existing IoT infrastructure, the system seamlessly connects with temperature monitoring, IV monitoring and environmental monitoring subsystems. Widely adopted in wards, ICUs and operating rooms, it digitally improves hand hygiene compliance and cuts hospital-acquired infection risks fundamentally.
