Abstract : A highly reliable and robust functioning liquid infusion system for use in biomedical applications comprises a dual microcontroller system where the first microcontroller is configured to administer the liquid and the second microcontroller is configured to monitor the accurate functioning of the system and various performance parameters such as flow rate of liquid, presence of leaks or blocks in the liquid passage, level of drug in the cartridge and battery condition. The liquid injection portion comprises a cylindrical airtight liquid holder or drug cartridge with a movable internal piston that is in contact with a movable stem, and a micromotor, which controls the drug delivery. The system is programmable with a dosing system stored into the driver/monitor microcontrollers. A low power LCD module is used to display the operating parameters with multiple language interface and alarm conditions, if any. The system is also equipped with a system of sensors that trigger an alarm to indicate abnormal conditions.
