System and method for the integration of fused-data hypoglycaemia alarms into closed-loop glycaemic control systems

摘要

Methods and systems are described for controlling a flowrate of insulin infused into the body of a patient. An insulin infusion device (58) infuses insulin into the body of the patient. A first sensor (52) generates BGL data indicative of a blood glucose level of the patient. A second sensor (48) generates ANS data such as heart rate data dependent on at least one parameter of the patient's autonomous nervous system. A data fusion processor (56) receives the BGL data and the ANS data and generates an output alarm signal if a hypoglycaemic event is inferred. A flowrate of insulin of the insulin infusion device may be modified dependent on the output alarm signal.
