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

To Evaluate the Efficacy and Safety of the Insulin Patch Pump System in Patients With Diabetes: A Prospective, Randomized, Positive Parallel Controlled, Open-label, Multicenter, Non-inferiority Clinical Trial.

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.

Study Overview

• Status: Completed
• Conditions: Type 1 Diabetes; Type 2 Diabetes
• Intervention / Treatment: Device: Insulin Patch Pump System; Device: Minimed 700

Detailed Description

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).

8. For patients whose researchers have determined that there are adverse conditions in the skin area where the insulin pump is implanted (such as subcutaneous nodules, subcutaneous fat hyperplasia, subcutaneous fat atrophy, skin scarring, skin infection, skin edema, etc.) that affect the injection and absorption of the medication;
9. Within 14 days prior to enrollment, and during the trial period, the participant had used and planned to use systemic glucocorticoids (excluding inhalation, topical eye medication, or local application);
10. During the screening process, the laboratory test indicators must meet the following criteria: ① Liver function impairment: ALT or AST is greater than 3 times the upper limit of the normal value; ② Kidney function impairment: Serum creatinine is greater than 1.5 times the upper limit of the normal value.
