背景：胰島素注射為糖尿病患控制血糖效果最佳的治療方式之一，然而胰島素在注射過程中可能因為針扎而導致病人生活品質下降，甚至不願意施打而造成疾病惡化。目的：藉由臨床觀察、蒐集施打者使用筆型胰島素針扎時機之不良經驗，製作出可協助移除筆型胰島素針頭之卸針座，降低施打者雙手在裝卸針頭時直接接觸針頭的風險，並提升使用者滿意度。方法：利用3D列印，製作出以ABS樹脂為材質的筆型胰島素注射器安全卸針座—「針小心」，結合臨床施打胰島素常見的問題製作前後測問卷，並依此蒐集受測者資料，比較前後滿意度。結果：在使用者回饋上，卸針座的應用可讓使用者更易於胰島素注射，並得到大部分問項上皆有所改善的結果。結論：「針小心」在使用上可提升醫療安全性，另也使使用者更便於進行胰島素注射，未來也將持續針對使用者回饋意見進行改善。

Background: Insulin injection is one of the most effective treatments for glucose control. However, insulin injections may lead to a decrease in quality of life for patients due to needle sticks during the injection process, and may even result in disease exacerbation if patients are reluctant to undergo injections. Purpose: Given the clinical observation and the collected feedback from unsatisfied insulin injection experiences, we presented a needle remover designed for removing needles from pen injections. It aims to alleviate the risk associated with needle loading/unloading and improve user satisfaction. Methods: We have developed a novel needle remover called "Bye2NeedleStick" using 3D printing technology. In addition, we administered questionnaires related to clinical practicesto assess user satisfaction. Results: Given user feedback, the application of "Needle Care" can make it easier for users to inject insulin and lead to improved results to most of the survey questions. Conclusions: The "Bye2NeedleStick" needle remover for insulin pen injection can improve safety, usability, and reduce risks in clinical use. The product will continue to be improved addressing potential issues from the feedback of users.
