Nasal sprays, which work on the Venturi principle, have the disadvantage of suck-back which makes them unhygienic for use in more than one patient. In Wrexham we have developed a disposable nasal spray system, which is safe and would be of benefit to other ENT departments.
基于文丘里原理工作的鼻喷雾剂存在回吸问题，这使得它们在多个患者中使用时不卫生。在雷克瑟姆，我们开发了一种一次性鼻喷雾系统，该系统安全且对其他耳鼻喉科部门有益。
