The control means includes a microprocessor, a permanent memory containing a series of fixed software instructions, and a memory for storing prescription schedules, dosage limits and other data. The microprocessor actuates the pump in accordance with programmable prescription parameters and dosage limits stored in the memory. A communication link allows the control means to be remotely programmed. The control means incorporates a running integral dosage limit and other safety features which prevent an inadvertent or intentional medication overdose. The control means also monitors the pump and fluid handling system and provides an alert if any improper or potentially unsafe operation is detected.Other References
