Problems solved by technology

Even so, bias in the estimation of meal size is difficult to avoid, so it is easy to produce postprandial hypoglycemia due to excessive insulin input
And there are many diabetic patients will have nocturnal hypoglycemia, and generally nocturnal hypoglycemia occurs in sleep, which is not easy to be noticed
However, all current insulin pumps can only input insulin to lower the patient's blood sugar, but they are powerless against possible hypoglycemia

Abstract

The invention discloses an intelligent micropump for switching between insulin infusion and glucagon infusion, belonging to the technical field of electrical equipment. The intelligent micropump can effectively stabilize the blood sugar of a patient in a safe range, and can be widely applied to type 1, type 2, special type and gestational diabetic patients. In the application, an intelligent method for simultaneously infusing insulin and glucagon based on a switching control theory is designed. The intelligent micropump for switching between the insulin infusion and the glucagon infusion is composed of a public motor, a needle and two independent sets of medicine storage and infusion systems; in a normal mode, the insulin is infused to the patient, and in a special mode, the glucagon is infused to the patient by switching the infusion system. The original function of capability of infusing one treatment medicine only is expanded that two different treatment medicaments can be respectively infused. Therefore, compared with the prior art, the multi-functional micropump has the characteristics of high integration, high safety and the like, and can distinctly improve the control effect of blood sugar.

Description

technical field [0001] The novel micropump relates to a portable injection device that can regularly and quantitatively inject insulin and glucagon into the human body, and can help diabetic patients maintain safe and stable blood sugar throughout the day. Automatic device for reusable insulin and glucagon infusion. Background technique [0002] With the improvement of material living standards and the deterioration of the environment, diabetes has increasingly become an important disease that seriously endangers human health. The number of diagnosed diabetic patients in my country is as high as 92.4 million, becoming the country with the largest number of diabetic patients in the world, and the incidence rate is as high as 9.7%, which means that 1 out of every 10 adults will be diabetic. We all know that diabetes is a deadly disease. Diabetes is the leading cause of blindness, kidney failure, and lower limb amputation, as well as death from cardiovascular complications. ...
