Open-loop intelligent insulin pump control method

Abstract

The present invention relates to a method of controlling the amount of insulin before meal. The present invention confirms whether the action of residual active insulin is taken into account by judging whether conventional or rapid-acting insulin is injected within a certain period of time. When taking the action of residual active insulin into account, the method of interpolation and numerical integration is adopted to accurately measure the residual amount of in vivo active insulin according to insulin pharmacodynamical data, thus more accurately measuring the insulin amount required before meal. The present invention can effectively reduce hyperglycemia / hypoglycemia caused by improper insulin amount, thus making the treatment more accurate and safer. In addition, the concept and method of measuring insulin amount provided by the present invention is also applicable to the measurement of insulin amount not before meal, which deserves promotion and application.

Description

technical field [0001] The invention relates to a control method of an open-loop intelligent insulin pump. Background technique [0002] Diabetes is a chronic disease that endangers the health of the social population. Its degree of harm ranks third among all diseases and continues to increase. Practice has proved that insulin is the most effective drug for controlling blood sugar and preventing various serious complications. Since the human body's demand for insulin is expressed in two forms: a continuous basal amount and a relatively large dose (supplementary amount) after a meal, insulin injection therapy is also designed for this characteristic. The traditional injection method is manual injection, that is, clinicians or patients manually inject long-acting or ultra-long-acting insulin once a day to meet the basic needs of the human body for insulin. In addition, short-acting or fast-acting insulin is administered before each meal Injection is to meet the needs of post...

Problems solved by technology

[0006] However, the calculation of residual active insulin is a very professional and complicated work, let alone patients, even full-time medical staff are often difficult to complete

Because it is too difficult, clinically, doctors either ignore it or roughly estimate it according to an empirical value (such as linear decay at a rate of 15-30% per hour), and it is even more difficult for patients to inject themselves, resulting in large fluctuations in blood sugar levels. Difficult to achieve ideal level
