Inclusion Criteria: 1. Age is ≥18 years and ≤ 75 years old, gender not restricted; 2. Body Mass Index (BMI) \< 30 kg/m²; 3. Patients diagnosed as type 1 diabetes or type 2 diabetes according to WHO standards (1999), and requiring intensive insulin therapy; 4. HbA1c \> 7.0% and ≤ 12.0%. Exclusion Criteria: 1. Those who had used any of the following insulin secretagogues or incretin drugs 14 days prior to enrollment, including sulfonylurea drugs, glinide drugs, dipeptidyl peptidase IV inhibitors (DPP-4i), and glucagon-like peptide-1 receptor agonists (GLP-1RA), among which the weekly formulation of exenatide for GLP-1RA needs to be extended to 70 days prior to enrollment; 2. Pregnant or lactating women; 3. Patients with acute metabolic complications of diabetes (such as diabetic ketoacidosis, non-ketotic hyperosmolar coma, lactic acidosis, etc.) or with hyperglycemia who are receiving intravenous antibiotic treatment due to infection; 4. Within the 28 days prior to enrollment, there was a history of a severe hypoglycemic event (Grade 3 hypoglycemia: without a specific blood glucose threshold, involving severe events with changes in consciousness and/or physical condition, requiring assistance from others); 5. Include patients with other endocrine disorders that may cause abnormal blood sugar levels, such as Cushing's syndrome, primary aldosteronism, and endocrine gland tumors; 6. Patients with acute-stage cardiovascular and cerebrovascular diseases; 7. Patients with a history of allergy to insulin, insulin pump adhesives, or subcutaneous infusion tubes; 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.
