In order to further improve the treatment level of diabetes, our hospital has introduced several latest insulin pumps manufactured by Dana Corporation of Korea. Now, we would like to briefly introduce the application knowledge of insulin pump. An insulin pump is a device that is shaped and sized like a beeper and infuses insulin continuously into the body through a hose connected to the human body. It simulates the physiological mode of insulin secretion by the healthy human pancreas. It is commonly known as “artificial pancreas”. The sensitive drive motor slowly pushes insulin from the reservoir into the subcutaneous through the infusion catheter in accordance with the dosage required by the human body to keep the blood sugar stable throughout the day for the purpose of controlling diabetes: the characteristics of human insulin physiological function: small amount and continuous insulin secretion. The most important feature of insulin pump: basal rate (small amount, continuous), making the insulin given more physiological and rationalizing the basal secretion of insulin in human physiological state, it not only secretes a small amount of insulin every 3-5 minutes, but also has peaks and valleys throughout the day, making the blood sugar stable, normal and more perfect. Three benefits of treating diabetes with insulin pump One, treating diabetes with insulin pump can effectively control and delay the complications. Insulin pump simulates physiological secretion and stable insulin absorption, so blood glucose control is smooth and up to standard, and complications are controlled and delayed for 15.3 years. It prolongs life expectancy by 5.1 years. International evidence-based medical research has confirmed that: insulin pump treatment can reduce the risk of the following complications: retinopathy by 76%; neuropathy by 60%; renal disease by 54%; and various cardiovascular events by 42%. Second, treating diabetes with insulin pump can increase patients’ freedom of life. Third, while treating diabetes with insulin pump, patients can still eat and sleep normally. The indications for insulin pump therapy include the following groups of people: 1, mainly for type 1 diabetic patients, especially those with “difficult to control”, “variable”, “fragile” type 1 Diabetic patients. 2, diabetic ketoacidosis, hyperosmolar coma and other patients. The basal volume can be increased according to the blood glucose level, and the “acceleration” time can be shortened (2 to 4 hours), which can replace the small dose insulin intravenous method. 3. Microvascular complications. Foreign reports can reduce the amount of trace protein or even disappear. It can be used in the treatment of diabetic nephropathy and retinopathy. 4.Improve diabetic neuropathy. 5.Relieve new onset of diabetes. 6.Applicable to diabetic women who are pregnant or diabetic women who wish to be pregnant after marriage. 7.Heavy diabetes mellitus type 2, difficult to control with previous methods or combined with serious infection, can be considered. 8.When diabetic patients must undergo larger surgical procedures. 9.Patients who have irregular life due to work, and it is very difficult to control blood sugar stably with insulin injection therapy. Insulin pump brings not only health, but also knowledge and science to diabetic patients. The first thing that insulin pump treatment brings to diabetic patients is the change of their attitude towards the disease: they pay more attention to their blood sugar level; they are more eager to understand and learn the knowledge about controlling diabetes; they are more willing to discuss with physicians, patients and diabetes education nurses, and gradually achieve excellent control of blood sugar in continuous communication, discussion and practice, and improve their self-confidence in overcoming the disease, and at the same time unconsciously improve They are more willing to discuss with physicians, patients and diabetes education nurses.
