Study for usability and safety improvement of insulin injection equipments

老年糖尿病患者在增加。他们中的许多人不能自己注射胰岛素，由护理人员注射胰岛素的情况有所增加。对于护理人员和患者，我们寻找安全且易于使用的胰岛素注射器。我们对注射设备的可用性进行了评估，并预测了使用高速相机和听力医务人员的改进。在护理人员的注射中，重要的是医疗防御感染显然比功能评估更重要。揭示了厚胰岛素装置在护理人员注射胰岛素时对患者稳定性的优势。最后，为了防止针刺伤，我们制作了一个胰岛素装置安全取针的原型，并展示了其有效性。

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.
