Ocamar Healthcare Mobile Computer (Personal Digital Assistant) includes 4G and 5G versions customized for hospital mobile nursing. Powered by Android 12 OS and octa-core CPU, it seamlessly connects with hospital HIS, EMR and LIS systems. Supported by 5G, dual-band Wi-Fi, Bluetooth and optional UHF RFID, the terminal covers eight core clinical workflows: patient ID verification, medication check, bedside vital sign entry, specimen collection, drug traceability and medical asset management. Equipped with patented 10° golden scanning angle and IP67 medical-grade rugged design, it supports multi-factor authentication including fingerprint, facial and AI voice control with built-in pupil exam flashlight. Resistant to repeated medical disinfection and all-day battery endurance, it eliminates paper-based nursing documents, synchronizes bedside data in real time and cuts medical errors for wards, ICUs and operating rooms.
