Insulin is widely used in treating diabetes, but still needs to be administered by needle injection. This study investigated a new needle-free approach for insulin delivery. A portable powder needleless injection (PNI) device with an automatic mechanical unit was designed. Its efficiency in delivering insulin was evaluated in alloxan-induced diabetic rabbits. The skin irritation caused by the device was investigated and the results were analyzed in relation to aerodynamic parameters. Inorganic salt-carried insulin powders had hypoglycemic effects, while raw insulin powders were not effective w...

研究目的：胰岛素在临床上广泛用于糖尿病的治疗,但需要注射方式给药,给患者带来不便。本文报道了一种胰岛素粉末无针注射给药的新方法,并对其给药效率和皮肤刺激性进行评价。创新要点：首次报道了胰岛素粉末无针注射给药方法,有望为糖尿病患者长期自我给药提供便捷。研究方法：自主设计便携式自动无针粉末注射给药装置,采用计算机辅助方法计算给药装置的主要空气动力学参数;采用家兔评价无针粉末注射对皮肤的刺激性,并分析与空气动力学参数的相关性;采用四氧嘧啶诱导家兔糖尿病模型,评价不同无机盐载药的胰岛素粉末的无针注射给药降糖效果。重要结论：采用自主设计便携式自动无针粉末注射给药装...
