Portable Diagnostic Cuff

Wraps a wrist, ankle, or suit-port limb and reads pulse, pressure, oxygenation, temperature, and the ugly rhythms that mean a patient should stop arguing. Conductive gel smells iodine-and-copper; wipe the liner, dry the sensor teeth, store loose rather than cinched. Lives beside the trauma bag—sickbay is often three ladders too far. Optional sealed cuff-pad link dumps a reading to a deck slate; default is offline-only so a dirty berth mesh cannot rewrite vitals. A dirty cuff misreads sweat as perfusion. Matte polymer shell, blunt latch, A cell under a service door—no fitness-band cosplay, no short-range Earth personal radio branding.
