The Safeguard Medical NIO Simulation Units deliver elite, high-fidelity instructional training solutions designed to master intraosseous vascular access without consuming live emergency inventory. The adult simulator (NIO-S-A) features sophisticated electronic internal systems complete with integrated LED feedback lights that guide users through proper surface pressure, timing, and mechanical deployment sequences. The infant simulator (NIO-S-I) provides tactile replication of the manual stepped needle configuration required for neonates. Both non-sterile models eliminate physical needle exposure, allowing instructors to manage highly repetitive, realistic training laboratory scenarios safely.
