Abstract
Many countries have been eagerly proposing legislation to replace traditional syringes with single-use safety syringes. Usability evaluation of three most commonly used safety syringes is conducted in this study. By administering the Safety Feature Evaluation Form and Focus Group Interviews on six professional nurses with an average professional experience over 11 years, usability problems with the above three types of safety syringe are found out. Furthermore, six designing principles have been concluded, and a new safety syringe design is made by a number of designers, nursing professionals and occupational safety technicians.
