[0002] Insulin is a protein hormone secreted by the pancreatic β-cells in response to stimulation by endogenous or exogenous substances such as glucose, lactose, ribose, arginine, and glucagon. Insulin is the only hormone in the body that lowers blood sugar, while also promoting the synthesis of glycogen, fat, and protein. Insulin is administered subcutaneously to the patient's abdomen using a targeted device.

[0003] Patent application CN109701124A discloses a clock-type positioning device for subcutaneous injection of insulin in the abdomen. Paragraph 0012 of the specification discloses that: the right end of the steering positioning piece B has a circular pointing piece integrally formed, and the steering positioning piece has eight hollowed-out circular buckle holes integrally formed. The eight circular buckle holes are evenly distributed among each other. The two circular buckle holes located in the middle can be fitted with the center point, and the circular buckle holes located on the side can be fitted with the buckle point.

[0004] However, in practical applications, the steering positioning plate needs to be rotated on one side of the circular positioning ring, and the position for subcutaneous insulin injection in the patient's abdomen needs to be determined through the circular buttonhole.
