To Evaluate the Efficacy and Safety of the Insulin Patch Pump System in Patients With Diabetes.

Patients will be enrolled and randomly assigned to either the test group or the control group for short-time intensive insulin therapy in inpatient setting. The test group will receive treatment with the Insulin Patch Pump System, while the control group will be treated with the Medtronic MMT-1805 insulin pump (MiniMed 700). The treatment period will last 7 days, during which blood glucose monitoring will be conducted in both groups.

The efficacy and safety of the Insulin Patch Pump System for insulin infusion therapy in patients with diabetes are evaluated by comparing it with the MMT-1805 insulin pump (MiniMed 700). This clinical trial employs a prospective, randomized, active-controlled, open-label, multicenter, non-inferiority design. On Day 0 (baseline), all participants maintain their pre-existing antidiabetic regimens to collect baseline glucose data. From Day 1 to Day 7, patients undergo a 7-day course of intensive insulin pump therapy. The test group receives treatment with the Insulin Patch Pump System, while the control group is treated with the Medtronic MMT-1805 insulin pump (MiniMed 700). During the intervention, participants receive standardized diabetic hospital meals and perform eight-point daily capillary blood glucose (BG) monitoring. Concurrently, continuous glucose monitoring (CGM) is maintained. Glycated albumin (GA) levels are assessed at baseline (Day 0) and post-treatment (Day 8).
