一种腰带式防抖动胰岛素注射器A belt type anti-shake insulin syringe

技术领域technical field

本发明涉及医学技术领域，具体为一种腰带式防抖动胰岛素注射器。The invention relates to the technical field of medicine, in particular to a belt-type anti-shake insulin syringe.

背景技术Background technique

胰岛素是由胰脏内的胰岛β细胞受内源性或外源性物质如葡萄糖、乳糖、核糖、精氨酸、胰高血糖素等的刺激而分泌的一种蛋白质激素。胰岛素是机体内唯一降低血糖的激素，同时促进糖原、脂肪、蛋白质合成。外源性胰岛素主要用来糖尿病治疗，传统胰岛素笔是先旋转笔帽选择注射剂量，然后按压注射，但是此过程需要固定缓慢的按压注射，对于帕金森患者和老年人来说，手部的震颤会影响注射效果，同时此类按压注射也不容易控制注射速度。Insulin is a protein hormone secreted by pancreatic islet beta cells stimulated 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 promoting glycogen, fat, and protein synthesis. Exogenous insulin is mainly used for diabetes treatment. The traditional insulin pen is to rotate the cap to select the injection dose, and then press the injection, but this process requires fixed and slow injection.
