阅读说明：本技术 伸缩调向式口罩 (Telescopic direction-adjustable mask ) 是由 赵秀卿 于 2020-04-13 设计创作，主要内容包括：该发明涉及一种伸缩调向式口罩。在非典肺炎抗疫中,普通一次性口罩均含有防毒药剂,由此比较安全。其缺点是鼻和口对应的过滤材料区域之间,接触压力和张力比较大,导致呼吸气流产生的湿性及粘性浓度大,出现不良反应。我利用一只医务供氧面罩SIZE型改造,制成伸缩调向式口罩,特别适用于老人和儿童。(The invention relates to a telescopic direction-adjusting mask. In SARS epidemic prevention, the common disposable mask contains anti-virus medicine, so it is safe. The disadvantages are that the contact pressure and tension between the filter material areas corresponding to the nose and the mouth are relatively large, so that the humidity and viscosity concentration generated by respiratory airflow are large, and adverse reactions occur. I utilize a medical oxygen suppliment face guard SIZE type to reform transform, make flexible accent formula gauze mask, be particularly useful for old man and children.)
