The insulin pump is composed of a pump, a small syringe and an infusion tube. The small injector can hold up to 3 milliliters of insulin. After the syringe is loaded into the pump, the guide needle of the front end of the connected infusion tube is inserted into the patient´s subcutaneous, and then the piston of the small syringe is pushed by the spiral motor driven by the battery of the insulin pump and the insulin is injected into the body. The purpose is to simulate the secretory function of the pancreas and continuously push insulin into the user´s subcutaneous in accordance with the dose required by the human body to keep the blood glucose stable all day so as to control diabetes.
