Novel insulin pump

Abstract

The invention discloses a novel insulin pump, which comprises a blood sugar detection system, a control system and an insulin injection system, wherein the blood sugar detection system comprises a blood sugar sensor and a wireless transmitting module which is connected with the blood sugar sensor; the blood sugar detection system can be used for continuously detecting the blood sugar content of a diabetic patient, and can be used for transmitting the blood sugar content to the control system in a wireless way; the control system comprises a wireless receiving module for receiving blood sugar data transmitted by using the blood sugar detection system, and a microcontroller system; the wireless receiving module is used for transmitting the received blood sugar data to the microcontroller module; and the dosage of insulin required be injected is obtained by calculating with a micro-controller and correcting with a model. In the novel insulin pump, a closed-loop insulin injection way is adopted innovatively, the working principle of secretion of insulin from the pancreas of a normal human body is simulated, and the blood sugar data of the patient is measured by using the blood sugar detection system. According to the novel insulin pump, the injection dosage of insulin can be adjusted in real time according to the blood sugar content of the patient, so that the aim of accurately injecting insulin is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of insulin dosage injection control for diabetic patients, and in particular relates to a novel insulin pump capable of real-time detection of blood glucose of patients and adjustment of injection dosage according to the measured blood glucose data. Background technique [0002] Diabetes is a serious, chronic, non-communicable, lifelong disease. Under normal physiological conditions, the source and outlet of blood sugar are in balance, so the blood sugar concentration is relatively constant, which can maintain the normal glucose metabolism of tissue cells. Diabetes patients are mainly caused by the absolute or relative insufficient secretion of insulin in the patient's body. It mainly leads to increased sources of blood sugar and blocked outlets, resulting in elevated blood sugar concentrations. Insulin is a hormone produced and secreted by pancreatic β cells. It is the only endocrine substance that lowers ...
