You must know something about insulin pumps to use them. Some explanations are given in this article about what dosage form of insulin can be used in insulin pumps, what is the principle of insulin pump therapy, and whether it is possible to use insulin pumps without diet control. What you must know about insulin pumps What forms of insulin can be used in insulin pumps? Short-acting insulins and ultra-short-acting insulin analogues such as short-acting human insulin, lysergic insulin and menadione insulin can be used in insulin pumps. However, lysergic insulin and menthol insulin have a lower risk of glycemic control and hypoglycemia than short-acting human insulin, and are less likely to cause obstruction of the infusion hose. Therefore, human insulin analogues can be the first choice for insulin pumps. Medium- and long-acting, premixed insulins cannot be used for insulin pump therapy. What is the principle of insulin pump therapy? It simulates the physiological secretion function of human pancreatic beta cells and infuses insulin continuously for 24 hours. The infusion method is divided into basal amount and pre-meal amount. Basal amount: The amount of insulin is continuously infused in micro amounts for 24 hours, simulating the secretion pattern of human basal insulin. It is mainly used to control blood sugar at night, fasting and before meals. Pre-meal amount: It simulates the amount of insulin secreted by human body rapidly after meal. It is mainly used to control blood glucose 2 hours after meal. Is it possible to use insulin pump without controlling diet? Although the free control of insulin is better, it is not quite able to control blood sugar as well as normal insulin. Human physiological insulin secretion is an automatic process, which means that the corresponding dose of insulin is secreted automatically according to the level and time of blood glucose elevation. At present, the insulin pump is still in the “open-loop” stage and cannot “automatically” infuse the corresponding dose of insulin according to the rising level of blood glucose in a timely manner. The way and method of insulin infusion by insulin pump. In other words, the insulin pump simulates and cannot fully achieve the physiological insulin secretion in human body, and after using it, it cannot fully achieve “eating as you want”. It is worth mentioning that even though there may be a “closed-loop” insulin pump in the future, which can “automatically” infuse the appropriate insulin according to the level and timing of blood glucose elevation, the necessary diabetic diet principles should not be violated.
