摘要在急诊科，对气管插管机械通气患者采用开放式吸痰方式会导致呼吸道飞沫、气溶胶播散，污染周围环境及医务人员。传统人工鼻具有加温湿化效果，且能阻隔病原微生物，但不具备插入吸痰管的功能，在拔下人工鼻进行吸痰时，容易造成痰液喷溅，污染周围环境及医务人员，而额外增加密闭式吸痰装置又会增加患者的经济负担。为此，浙江省桐乡市第一人民医院急诊科医护人员设计了一种新型防喷溅吸痰功能人工鼻，在传统人工鼻的基础上增加了防喷溅吸痰功能，获得了国家实用新型专利（专利号：ZL 2021 2 0017615.0）。该人工鼻主要由容纳腔、连接管、吸痰管插管、密封瓣膜等组成，可以使用一次性吸痰管插入吸痰，同时能够防止分泌物喷溅，保证了密封性。该专利将人工鼻的湿化、阻隔病原体功能与防喷溅吸痰功能相结合，适合在急诊科和重症医学科使用，有一定的临床应用价值。

abstractsIn the emergency department, open endotracheal suctioning for mechanically ventilated patients with endotracheal intubation will lead to the spread of respiratory droplets and aerosols, polluting the surrounding environment and medical staff. The traditional heat-and-moisture exchanger has the effect of warming and humidifying, and can block pathogenic microorganisms, but it does not have the function of inserting a sputum suction tube. When the heat-and-moisture exchanger is pulled out for sputum suction, it is easy to cause sputum splash, which pollutes the surrounding environment and medical personnel. The addition of closed sputum suction devices will increase the economic burden on patients. Thus, the medical staff of emergency department of the First People's Hospital of Tongxiang City of Zhejiang Province designed a new type of heat-and-moisture exchanger with anti-splash sputum suctioning function and obtained the National Utility Model Patent of China (ZL 2021 2 0017615.0). The new heat-and-moisture exchanger is mainly composed of a receiving cavity, a connecting tube, a sputum suction tube intubation tube, a sealing valve, etc. The disposable sputum suction tube can be used to insert sputum suction, and at the same time, it can prevent the secretion from splashing to ensure sealing. The patent combines the humidification and pathogen blocking functions of the heat-and-moisture exchanger with the anti-splash sputum suctioning function, which is suitable for use in the emergency and critical care medicine departments and has clinically practical value.
