2020年4月 贝迪诺恩公开“小舱式多功能操作防护罩”设计文件

应对 COVID-19疫情过程中，为降低医生的感染，贝迪诺恩基于雷神山一线医生在餐巾纸上绘制的防护设备创意，设计并制造了“小舱式多功能操作防护罩”，屏蔽飞沫的溅射并通过负压将气溶胶吸出并无害化处理。
In order to reduce the risk of infection for doctors fighting against COVID-19, Bradynuoen designed and manufactured the INTUBATION PROTECTIVE SYSTEM based on the inspiration from the front-line doctors in Leishenshan Hospital, Wuhan, China. This device will block the sputtering of droplets and suck out the aerosol by negative pressure for harmlessization.

经武汉雷神山医院临床应用，该设备可用于各类传染性操作中，对操作者进行防护。该产品在中国为一类医疗器械（14-14-06隔离罩）。

This device has been applied in Leishenshan Hospital, Wuhan, China with intended use for various infectious procedures to protect the operators. This product is classified as Class I in China.

该产品可适用于：1）重症患者气管插管插入与移除过程；2）疑似患者的呼吸道分泌物样本采集过程；3）重症患者日常负压隔离；4）深静脉穿刺置管过程的防护。

Indications: 1) tracheal intubation insertion and removal in severe patients; 2) the sampling process of respiratory secretions of suspected patients; 3) daily negative pressure isolation for severe patients; 4) protection during deep venipuncture catheterization.

产品待改进的部分：1）操作孔位置应用于亚洲人群应调低5-10cm，其它地区人群待确认；2）非负压状态下，操作孔应修改为密封结构；3）依据当地医院习惯，修改管线口位置和数量；4）修改屏蔽帘方式，更利于密封；5）在装置尾端增加额外的负压装置，进一步减少气溶胶的泄漏；6）操作孔与防护罩连接建议采用软连接方式，便于医生操作；7） 防护罩内表面建议使用亲水防雾涂层，根据消毒方式选择永久涂层或临时涂层；8）负压源端病毒处理结构建议使用75%乙醇溶液+纯化水+活性炭三级装置。

This device can be improved as followings: 1) the position of operation hole should be lowered by 5-10 cm for Asian population, and to be determined for other population; 2) under the condition of non-negative pressure, the operation hole should be modified into a sealing structure; 3) the position and quantity of pipeline ports could be changed depending on local hospitals; 4) the form of sealing shade could be modified for better sealing; 5) additional negative pressure device at the end of the device can be installed to further reduce aerosol leakage; 6) soft connection is recommended for connection between operation hole and protective system, which is more convenient for doctors to operate; 7) hydrophilic anti-fogging coating is recommended on the inner surface of protective system, while permanent coating or temporary coating can be selected according to the disinfection method; 8) a three-stage device of 75% ethanol solution + purified water + activated carbon is suggested to use for virus treatment at negative pressure source end.

该产品发明创意来自上海市第一人民医院驻雷神山医疗队队员鲍伟副研究员、周妍主治医师、张鹏宇副主任医师。鲍伟，美国德州大学MD Anderson癌症中心妇科肿瘤系博士后。周妍，美国哥伦比亚大学病理及分子生物学系博士后。张鹏宇，上海交通大学医学院呼吸病学博士，美国德州大学MD Anderson癌症中心呼吸科访问学者。

The inspiration of this device was from Bao Wei (Postdoctor at MD Anderson Cancer Center), Zhou Yan (Postdoctor at Columbia University) and Zhang Pengyu (Visiting Scholar at MD Anderson Cancer Center) in Leishenshan Hospital team from Shanghai General Hospital.

在全球疫情蔓延的背景下，贝迪诺恩决定公开“小舱式多功能操作防护罩”设计文件。若您在生产、使用此防护罩时遇到任何问题，贝迪诺恩将在疫情期间开通每日“视频会议”，为您与国内一线医生建立沟通桥梁，在防护罩的生产、使用、改进上为您提供帮助。
