Description

Insulin pump

Technical field

What insulin pump of the present invention related to is a kind of portable electronic of insulin injection control insulin injection equipment in human body at regular time and quantity, can help diabetics in whole day, to keep stable blood glucose, be widely used in 1 type, 2 types, special type and diabetes in pregnancy patient.

Background technology

At present treatment of diabetes and control are mainly contained two kinds of methods: a kind of is conventional method treatment, promptly every day 1-2 insulin injection and 1-2 blood sugar monitoring; Another kind is to adopt the intensive treatment method, and every day is blood sugar monitoring repeatedly, and adjusts diet and insulin dosage, makes blood glucose near normal level as far as possible, and this kind method is to use insulin pump to realize more.

Once used above-mentioned two kinds of methods to carry out the long-term clinical trial of a maximum-norm about DCCT DCCT in 1993, and be intended to observe and strengthen the benefit that glycemic control is brought.Result of study shows, the average glycolated hemoglobin of the good group of glycemic control has descended 2% for bad group than glycemic control, greatly reduce the danger of chronic complicating diseases of diabetes: the danger of diabetes eye pathological changes has descended about 76%, the dangerous same degree of kidney and neuropathy obtained reduction.

Formally be applied to occur brshless DC motor formula insulin pump in succession after clinical at insulin pump; In form by control system, dynamical system, conveyer device 24 hours repeatedly self-timing quantitatively carry the insulin insulin pump to human body; The two 16 bit CPU control modes that adopt low power consuming are arranged, and adopting the reducing motor of band feedback is the insulin pump of half-closed loop control system; But these products do not have the safety assurance of two mutual check systems of CPU, and do not reserve closed loop blood sugar test port, have certain limitation on the safe in utilization and scalability of product.

Summary of the invention

The present invention seeks to provides a kind of insulin pump at above-mentioned weak point, can promote safety, ease-to-operate and the extensibility of insulin pump.This insulin pump adopts Switzerland's direct current generator of latest generation; Use software program accurately to control the control system of the mutual monitoring of two microcomputers; Reserve the world's high-end closed loop blood sugar test port simultaneously, be a kind of safety, easy, the insulin pump of complete function.
