附图说明
图 1为本发明的剖视示意图；
图中： 1-鼻孔状筒体、 2-过滤层、 3-鼻腔道、 4-鼻甲、 5-弧形瓣膜、 6- 进气口、 7-环形凸齿、 8-连接部。
具体实施方式 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图， 对本发明进行进一步详细说明。
如图 1所示， 本发明公开的仿生鼻塞， 包括鼻孔状筒体 1， 鼻孔状筒体 1的长度为 4至 10毫米， 外径为 5至 14毫米， 以适应各种人群的需求； 鼻 孔状筒体 1包括过滤层 2、 鼻腔道 3、 鼻甲 4、 鼻粘液， 鼻孔状筒体 1的外表 面设置有环形凸齿 7， 环形凸齿 7可设置多层， 使得鼻塞不易从人鼻中脱落。
鼻腔道 3为鼻孔状筒体 1中空部， 鼻甲由附着在鼻腔道内壁上的三个弧 形瓣膜构成， 三个弧形瓣膜沿鼻腔道轴线方向的正投影在同一圆周上均匀排 布， 弧形瓣膜为片状， 弧形瓣膜垂直于鼻腔道的内壁， 弧形瓣膜沿鼻腔道轴 线方向的尺寸小于沿鼻腔道径向方向的尺寸， 弧形瓣膜为弓形， 弓形的高度 为鼻腔道内径的四分之一到四分之三， 沿鼻腔道轴线方向交错布置， 形成曲 折通道， 使得空气通过鼻腔道 3的行程增大， 同时使吸入空气在鼻腔道 3中 形成回旋气流，有时间在鼻腔道 3内得以温暧和潮湿化后再送入下级呼吸道。
在鼻甲 4和鼻腔道 3的内壁上附着鼻粘液， 鼻粘液采用凝胶材料， 凝胶 材料由胶体材料、 成膜剂、 稳定剂、 消炎抗菌成分、 保湿剂和水构成， 胶体 材料 成膜剂包含天然的亲水性高分子包括多糖类（淀粉、纤维素、海藻酸、 透明质酸， 壳聚糖等） 和多肽类 （胶原、 聚 L-赖氨酸、 聚 L-谷胺酸等） 以 及合成的亲水高分子包括聚乙烯醇、 聚丙烯酸及其衍生物类（聚丙烯酸酯， 聚甲基丙烯酸， 聚丙烯酰胺， 聚 N-聚代丙烯酰胺）等， 稳定剂主要是表面活 性剂如吐温系列、十二垸基硫酸钠等，保湿剂主要是高沸点溶剂，如丙二醇， 丙三醇， 异丙醇等组成， 消炎抗菌成分有抗菌活性的药物和纳米金属成分， 如纳米金， 纳米银等。 过滤层 2位于鼻腔道 3后部出口处，过滤层 2内填充强吸附性的毛状物， 可采用纤维等材料制成， 如附有活性炭的泡沬海绵网状结构， 起到类似鼻毛 的作用， 过滤层 2的两端面为透气层， 进入鼻腔道 3的空气经过过滤层 2后 再进入人体鼻腔， 鼻腔道 3前端的进气口 6的横截面面积小于过滤层 2的横 截面面积。
本发明在使用时， 空气通过进气口 6进入鼻腔道 3中， 鼻甲 4和鼻粘液 吸附空气的尘埃等有害物质， 鼻粘液中的消炎抗菌成分可杀灭空气的细菌， 再经过过滤层 2进入人的鼻腔， 进一步的， 由于鼻甲 4交错布置的弧形瓣膜 5， 将空气流动的通道由直线改成曲折的通道， 使得空气在鼻腔道 3中的行 程增大， 同时增加空气和鼻粘液的接触面积， 更有利于鼻粘液的吸附和杀菌 效果。
通常使用时， 将两个鼻孔状筒体 1连接在一起， 方便使用， 两个鼻孔状 筒体 1之间采用挠性连接，连接部 8采用挠性部件， 由于挠性部件便于定型， 既方便不同人使用时两个鼻孔状筒体 1位置的固定， 又可以减少鼻孔状筒体 1对人鼻的压迫感 （相对于弹性部件连接） 。
当然， 本发明还可有其它多种实施例， 在不背离本发明精神及其实质的 情况下， 熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形， 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
