Study for usability and safety improvement of insulin injection equipments

老年糖尿病患者增多。他们中的许多人不能自己注射胰岛素，由照顾者注射胰岛素的案例增加了。对于护理人员和患者，我们搜索了安全易用的胰岛素注射器。我们评估了注射设备的可用性评估，并使用高速摄像机和听力医务人员预测了改进。护理者注射的重要一点是，对感染的医学防御显然是优先于功能评估的。并揭示了厚胰岛素装置的优势，特别是在照顾者给患者注射胰岛素时的稳定性。最后，为了防止针刺损伤，我们制作了一台安全取出胰岛素装置中的针头的样机，并展示了它的有效性。

Elderly diabetes patients are increase. Many of them can not inject insulin by themselves, and cases of insulin injections by caregivers increase. For caregivers and patients, we searched safe and easy-to-use insulin injectors. We evaluated injection equipments usability evaluation and predicted improvements using a high speed camera and hearing medical staff. The important thing at caregiver's injection is that medical defense against infection was clearly a priority than functional evaluation. And advantage of thick insulin device especially at when caregivers inject insulin to patients stability was revealed. Finally to prevent needle stick injury, we made a prototype to remove needles from insulin device safely and presented its effectiveness.
