An injection pump control method and control unit and an injection pump

Abstract

The invention relates to a method for controlling an insulin injection pump and also relates to a relevant control unit and the injection pump. The control unit comprises an anticipated plasma insulin concentration value obtaining module, a current subcutaneous and tissue space insulin concentration value obtaining module, a necessary injection value obtaining module, an injection command transmitting module and a counting module. The injection pump comprises a pump body and the control unit arranged in the pump body. According to the invention, the injection pump can be extremely convenient to use, so that the injection pump can be promoted to benefit vast patients.

Description

technical field [0001] The invention relates to a control method of a syringe pump, and also relates to a related control unit and a syringe pump. Background technique [0002] Diabetes is a chronic disease that seriously endangers human health in modern society. In practice, the use of insulin to control blood sugar and prevent various serious complications is the most effective. Since insulin cannot be taken orally, it has traditionally been injected using a syringe. At present, the use of syringe pumps for injections is also increasing. [0003] The syringe pump can better control the blood sugar concentration of diabetic patients, reduce blood sugar fluctuations, and reduce the incidence of hypoglycemia by regularly and quantitatively injecting insulin accurately, thereby improving the quality of life of patients. The advent of the syringe pump was once considered a boon for diabetics. However, the current level of popularization of syringe pumps is not high. In addi...

Problems solved by technology

However, this method cannot bring the patient's blood glucose concentration to the expected range quickly, and usually requires monitoring blood glucose four times a day, and constantly adjusting the dosage of insulin according to the blood glucose concentration

The initial setting of the dosage of the syringe pump is generally completed by medical staff. In order to find out the ideal dosage of insulin, diabetic patients often need to be hospitalized for about a week; if they choose the non-hospitalization method, it will take longer to complete the dosage setting of the syringe pump

In addition, since the types and quantities of meals patients may change each day, pump users must master the calculation method of pre-meal / meal additional amount, which puts forward higher requirements on the user's learning ability, and many patients cannot adapt to the and mastering while giving up pump therapy

On the other hand, clinicians have a variety of insulin preparations to choose from during routine treatment, including rapid-acting, short-acting, intermediate-acting, and long-acting insulins. Each preparation has its pharmacokinetic / pharmacodynamic characteristics and indications, but Syringe pumps only use fast-acting or short-acting insulin. This setting scheme is quite different from the daily treatment plan. Medical staff need to be trained to master this setting method. At present, most medical staff do not understand the setting scheme of this type of syringe pump. This also becomes a limiting factor for syringe pump applications
