Disposable Catheterless Insulin Pumps

Abstract

The invention provides a disposable non-catheter insulin pump. The disposable non-catheter insulin pump comprises a medicine storage unit, a dosing control unit, a dosing driving unit, an insulin indwelling unit and a skin heating unit, wherein the medicine storage unit is used for storing insulin; the dosing control unit is used for controlling input of the insulin; the dosing driving unit is used for pushing the insulin to the human body according to the best calculated dose of the insulin; the insulin indwelling unit comprises an insulin indwelling hose and is used for enabling the insulin indwelling hose for conveying the insulin stored in the medicine storage unit to be embedded in subcutaneous tissue of the human body; the skin heating device is used for heating skin tissue of the position where the insulin is pushed through the disposable non-catheter insulin pump; the skin heating device comprises a skin heating film, a temperature raising module, a temperature control module, a heat preservation module and a temperature detection module. The disposable non-catheter insulin pump can control the temperature of the skin of the human body, solves the problem of delay between the target blood glucose concentration and insulin peak acting time, and also shortens the insulin peak acting time.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an insulin pump, in particular to a disposable catheter-free insulin pump. Background technique [0002] The pancreas in the body of a normal person can automatically monitor changes in the glucose content in the blood of the human body and automatically secrete the required insulin. However, in diabetic patients, the body cannot normally secrete the insulin required by the human body, and the function of the human pancreas appears abnormal. Metabolic diseases caused by abnormal pancreatic function, diabetes is a lifelong disease. At present, medical technology is still unable to cure diabetes, and the occurrence and development of diabetes and its complications can only be controlled by stabilizing blood sugar. [0003] The current medical technology uses a glucose sensor implanted in the subcutaneous tissue of the human body to monitor the changes in human blood sugar in real time...

AI Technical Summary

Problems solved by technology

[0004] Since the temperature of the human skin surface will greatly affect the peak action time of insulin, the longer the peak action time of insulin, the worse the real-time regulation function of insulin on the blood sugar concentration of the human body. The surface temperature of human skin is usually between 32-37 degrees , the peak action time of insulin in this temperature range is longer, and the lower the temperature, the longer the time. At present, the traditional artificial pancreas system cannot solve the delay problem between the target blood sugar concentration and the peak action time of insulin, so it cannot realize the human blood sugar concentration. Real-time rapid adjustment

At present, the principle of blood glucose detection is mostly the enzyme chemical electrode method, but all reactions related to enzymes are affected by temperature, while the surface temperature of human skin will fluctuate due to the external environment and internal environment, which is unfavorable for blood glucose detection.
