Hand hygiene is one of the most important measures to prevent nosocomial infections. This paper introduced the design and application of a hand sanitiser bottle with timer. This hand sanitiser bottle has been designed to improve the cleaning and disinfection efficiency, and provided a more precise timing of fertilizer application. (手卫生是预防院内感染的重要措施之一。本研究设计一种带有计时器的消手液瓶, 简化计时操作, 有助于医务人员更精准地掌握消毒时间, 有效提高清洗消毒效率。)
