The IrDA wireless protocol has been applied to a fiber optics based point-of-care system for the detection of intravenous infiltration. The system is used for monitoring patients under infusion therapy. It is optimized for portability by incorporating a battery source and wireless communication. The IrDA protocol provides secure data communication between the electronic module of the system and the PDAs carried by the nurses. The PDA is used for initiating the actions of the electronic module and for data transfer. Security is provided by specially designed software and hardware.
