Abstract

The invention relates to a closed-loop insulin delivery device integrating a micropump and a microneedle array. The closed-loop insulin delivery device comprises a micropump device, an amicroneedle array and a drug delivery catheter connecting the amicroneedle array and the micropump device. The micropump device comprises a battery cover, a battery, a master control circuit board, a force sensor, a servo motor, a drug delivery device body, a boost screw, a drug storer piston and an external panel. The closed-loop insulin delivery device significantly reduces the pain of diabetic patients. The materials of the amicroneedle array are all recyclable, the recycling process is convenient, and no pollution is caused to the environment.

Description

technical field [0001] The invention relates to an insulin delivery device, in particular to a closed-loop insulin delivery device integrating a micropump and a microneedle array. Background technique [0002] Diabetes mellitus is a common chronic disease in which glucose metabolism and endocrine disorders lead to systemic metabolic disorders, and hyperglycemia is its main clinical feature. At present, clinically, the vast majority of diabetic patients inject insulin in divided injections, usually three times a day, 20 to 30 minutes before meals, and the injection site is usually the muscle. The fractional injection of insulin is simple and convenient, and patients can quickly master it by themselves. However, after long-term clinical observation and summary, its shortcomings are also very prominent. The main manifestations are: 1) Unstable blood sugar control, prone to hyperglycemia or hypoglycemia , bring pain and danger to patients; 2) Long-term blood sugar instability w...
