Description

鼻罩 技术领域
本发明涉及一种鼻部过滤装置， 用来防止花粉、 灰尘、 细菌、 病毒、 臭气粒 子等空气中微小悬浮颗粒被吸入人体，还可用作将药剂浸渍到吸湿性的罩部后再 将其汽化并使患者吸入的医疗用具， 以及在水中活动时做用来防水的鼻塞。 背景技术
目前， 已经公开的鼻罩的中国专利 94223499. 5、 97293967. 0、 98208041. 7、 02256345. 8、 03811499. 2、 200420050435. 9，及美国专利 7, 156, 099、 6, 971， 388、 6, 119， 690等。 这些公开的鼻罩由过滤装置和连接装置组成， 都是将过滤装置插 入鼻孔或者用过滤装置覆盖住鼻孔， 当使用者吸入空气时，过滤装置将空气中的 花粉、 灰尘等颗粒滤除， 另外， 上述某些鼻罩也兼具缓释挥发性药剂和用作防水 鼻塞等功能。
然而， 以往鼻罩由多个组件拼装而成， 结构较为复杂和松散， 在制作中难以 保证鼻罩的轻、 薄， 影响了鼻罩的舒适性。 同时， 各组件的接合部位也容易出现 渗漏， 一但因组件间连接不牢固而解体，使用者有可能将分散的组件吸入呼吸道 而带来危险。 另外， 以往鼻罩的过滤装置与连接装置不能拆分或不易拆分， 使两 组装置不易更换， 影响了鼻罩的适用性和多功能性。再有， 以往鼻罩的过滤装置 所在平面垂直于鼻前庭内壁， 受鼻前庭空间限制， 过滤面积较小， 影响了鼻罩的 透气性。此外， 以往鼻罩的过滤装置为圆形或椭圆形， 无法与鼻前庭内壁紧密贴 合， 存在侧漏现象， 过滤效果不佳。 发明内容
有鉴于以往鼻罩的上述弱点， 本发明提供一种结构简洁的鼻罩， 此鼻罩对过 滤装置和连接装置进行了内部集成， 因此鼻罩仅由三个组件插接而成， 且插接部 位牢固、 紧密， 使鼻罩更加轻、 薄， 提升了佩戴的舒适性， 同时， 又避免了组件 间隙渗漏和组件解体等问题。
本发明要解决的另一技术问题是提供一种多功能鼻罩， 其三个组件通过插接 方式连接，插接处可以拆分， 因此可以将具有多种功能的不同过滤装置有选择的 安装在鼻罩上， 使鼻罩实现多种功能， 例如： 滤除花粉和细菌等空气中微粒的过 滤功能， 释放挥发性药剂的治疗功能， 以及游泳时的防水功能等。 另外， 当过滤 装置或连接装置与鼻部尺寸不匹配时，可以更换成其他型号， 从而提升了鼻罩的 适应性。
本发明要解决的又一技术问题是提供一种透气性更好的鼻罩， 其过滤装置采 用倾斜式设计， 使过滤装置所在平面倾斜与鼻前庭内壁，利用斜截面大于横截面 的原理， 增加了过滤装置的过滤面积， 提高了鼻罩的透气性， 让使用者呼吸更加 顺畅。
本发明要解决的再一技术问题是提供一种边缘密闭性更好的鼻罩， 通过将过 滤装置的边框设计成边角圆滑的肺叶型，使其外形与鼻前庭内腔形状相吻合。将 鼻罩***鼻前庭后，过滤装置的边框与鼻前庭内壁紧密贴合，可防止侧漏的发生， 同时鼻罩也不会将鼻孔撑大， 因此不会损害使用者的面部美观。
本发明解决上述技术问题所采用的技术方案是： 此鼻罩由一对过滤装置和一 个连接装置组成。
过滤装置包含过滤器和边框两部分。 过滤器外形为片状， 边框外形为环状， 过滤器的厚度小于边框的厚度。过滤装置为集成式设计， 其特征在于： 边框环绕 于过滤器四周， 过滤器边缘***边框内部，边框包裹住过滤器边缘并与其紧密粘 合， 从而将过滤装置集成为一体化的组件。边框靠近鼻中隔一侧有一个插孔， 供 连接装置的插头***。
过滤器既可以是滤材， 通过自身的小孔来滤除空气中的花粉、 灰尘、 细菌、 病毒、 臭气粒子等微小颗粒； 也可以是具有透气性和吸湿性的纤维材料， 用来浸 渍药剂或携带有稀释药剂效果的微胶囊， 再利用药剂的挥发性， 让使用者吸入来 达到医疗的目的； 还可以是无渗透性材料， 使用者在水中活动时可以用来防水； 另外，用作防水用途时，过滤装置还可以由一整块防水材料制成，用作防水鼻塞。
连接装置是用同种材料做成的一个整体性组件， 包含梁和插头两部分。 连接 装置的外形为弯弧形， " U "形和 "C "形可以作为其两个特例。 连接装置的两端 为插头， 两个插头之间的连接部分为梁。插头为两边粗中间细的哑铃形， 插头顶 端较粗的部分称为"帽"、中间较细的部分称为"杆"、下部较粗的部分称为"垫"。 将插头***过滤装置边框的插孔内，边框套住插头的杆部，插头的帽和垫卡在边 框的两侧， 从而将鼻罩连接成一体。插孔和杆的横截面大小和形状相同， ***后 二者完全吻合， 上述横截面的形状不能为圆形， 以保证***后过滤装置不会绕杆 发生旋转。
将鼻罩连接装置的两端连同过滤装置***鼻前庭，***深度不超过 15mm， 以 防刺激鼻腔的敏感部位。此时， 过滤装置的边框与鼻前庭内壁贴合， 连接装置可 以利用自身的弹性使自己的两个分支夹住鼻中隔实现鼻罩的固定， 另外，连接装 置也可以利用自身的弹性使过滤装置的边框夹住鼻中隔实现鼻罩的固定。鼻罩插 入鼻前庭后， 其主要部分隐藏于鼻前庭内， 只有梁的一部分露在鼻外， 无损鼻部 的美观。
通过上述设计， 鼻罩由一对过滤组件和一个连接组件插接而成， 使整个鼻罩 的结构更加简洁、 牢固， 因此可以将鼻罩制造得更加轻、 薄， 以增加使用的舒适 性， 还避免了组件间隙的渗漏和组件解体等问题。
另外， 由于鼻罩的过滤装置和连接装置在插接处可以拆分， 因此可以更换不 同功能的过滤装置而实现滤除空气中微小颗粒、缓释挥发性药剂以及防水等多重 功能多种功能。 另外， 当过滤装置或连接装置与鼻部尺寸不匹配时， 还可以更换 成其他型号， 从而提升了鼻罩的适应性。
上述过滤装置边框的材料可以是较为柔软、 富于弹性且无毒的塑料、 树脂、 尼龙、 硅胶或以这些材料为基础的合成物。
上述连接装置的材料可以为富于弹性且无毒的金属、 塑料、 树脂、 尼龙、 硅 胶或以这些材料为基础的合成物。
上述过滤装置的过滤器的材料可以为滤材。 此滤材可以为滤网结构、 织布、 无紡布、 有过滤效果的泡棉、 活性炭、 纤维素海绵。 上述滤网结构的滤材， 其材 质可以为金属、 塑料、 尼龙、 聚酯、 化纤或以这些材料为基础的合成物。
上述过滤装置的过滤器还可以是具有透气性和吸湿性的纤维材料， 此材料可 以浸渍挥发性药物或携带有稀释药剂效果的微胶囊。此纤维材料可以为泡棉或无 纺布。
上述过滤器的材料还可以是不透水的材料， 例如： 橡胶、 硅胶、 塑料。 上述 鼻罩用作防水用途时，其过滤装置还可以由一整块上述防水材料制成， 用作防水 鼻塞。
上述过滤装置的形状可以是圆形、椭圆形或适合于鼻前庭内腔使用的不规则 形状。在一个优选的实施例中，其过滤装置为边角圆滑的肺叶形，其形状特点为： 靠近鼻尖一端较窄，靠近面部一端较宽，靠近鼻中隔一侧为直边或略有弯度的曲 边， 靠近鼻翼一侧为弯度稍大的曲边， 各边角处均圆滑。 由于此形状与鼻前庭内 腔形状相吻合， 鼻罩***鼻前庭内后， 过滤装置边框与鼻前庭内壁紧密贴合， 可 以防止过滤装置与鼻前庭内壁间出现缝隙，避免了侧漏。过滤装置的大小以及长 宽比例可以适当调整，以适应不同形状的鼻前庭。另外，由于边框采用弹性材料， 可以进一步促进边框与鼻前庭内壁的贴合，从而提高鼻罩对不同鼻前庭形状的适 应性。
上述鼻罩的连接装置， 其顶端可以是弯曲的， 即插头与梁的接合部可以是弯 曲的， 弯曲的方向和角度可根据需要加以选择。在应用中， 过滤装置可以选择顶 端弯曲情况不同的连接装置而实现不同的***姿态。在一个实施例中，鼻罩采用 倾斜式设计， 其插头的中轴线倾斜于梁所在的平面 （夹角成锐角）， 此时过滤装 置所在平面也会倾斜于梁所在的平面。当鼻罩***鼻前庭后， 由于梁所在平面与 鼻前庭中轴线平行， 此时过滤装置所在平面则与鼻前庭横截面（垂直于鼻前庭中 轴线的鼻前庭截面）保持倾斜姿态。根据斜截面（倾斜于鼻前庭横截面的鼻前庭 截面）的面积大于横截面的原理， 过滤装置的面积较以往鼻罩得到了扩大（以往 鼻罩的过滤装置处在鼻前庭的横截面上）， 因而提升了过滤装置的透气性， 让使 用者的呼吸更加顺畅。
本发明的有益效果是， 其结构简单， 便于制作更加轻、 薄和牢固的鼻罩， 同 时也降低了过滤装置的组件间隙泄漏以及组件解体后的吸入风险； 另外，过滤装 置和连接装置可以更换， 一方面可以有选择的使用不同功能的过滤装置，使鼻罩 具备更多的功能， 另一方面还可更换不同尺寸的组件， 增加了鼻罩的适用性； 再 有， 过滤装置外形可设计为圆滑的肺叶形， 实现鼻罩与鼻前庭内壁的无缝接合， 防止鼻罩的侧漏； 还有， 可以通过鼻罩的倾斜式设计， 扩大过滤装置的面积， 增 加鼻罩的透气性， 使呼吸更加顺畅。 附图说明

作为一个优选的实施例， 在图 1中， 鼻罩包含一对过滤装置 （2 ) 和一个连接 装置 （1 )， 结构简单、 轻薄， 易于制作。 其过滤装置 （2) 包括边框 （8)和过滤 器 （9 ) 两部分。 连接装置包含插头 （3 ) 和梁 （4) 两部分。 连接装置 （1 ) 的插 头（3 )***边框（8 )靠近鼻中隔（13 ) (参考图 5 )—侧的插孔（10) (参考图 4) 中， 实现鼻罩的连接。 过滤装置 （2 ) 为边角圆滑的肺叶形， 其形状特点为： 靠 近鼻尖一端较窄， 靠近面部一端较宽， 靠近鼻中隔（13)—侧为直边或略有弯度 的曲边， 靠近鼻翼一侧为弯度稍大的曲边， 各边角处均圆滑。将鼻罩***鼻前庭 (14) (参考图 5)后与鼻前庭（14) 内壁紧密贴合， 可有效防止侧漏。 边框（8) 和连接装置 （1) 的材料可以为有弹性且无毒的塑料、 树脂、 尼龙、 硅胶或以这 些材料为基础的合成物。 作为一个实施例， 此处的过滤器 （9) 为滤材， 可以为 滤网结构、 织布、 无纺布、 有过滤效果的泡棉、 活性炭、 纤维素海绵， 用于滤除 空气中的微小颗粒。
在图 2中， 作为一个实施例， 此处其连接装置 （1)为 "C"形， 连接装置（1) 的插头 （3) ***过滤装置 （2) 的边框 （8) 后， 通过插头的帽 （5) 和垫 （7) 夹住边框（8)， 实现鼻罩的连接。插接部位接合紧密， 不易解体， 也无泄漏发生。 将连接装置 （1) 的插头 （3) 从边框 （8) 中拔出， 即可实现二者的拆分， 因而 连接装置（1)和过滤装置（2)这两个组件可以根据功能和尺寸的需要进行更换。 插头 （3) 的中轴线倾斜于梁 （4) 所在的平面 （夹角成锐角）， 当鼻罩***鼻前 庭 （14) 后， 梁 （4) 的平面与鼻前庭中轴线 （11) (参考图 5) 平行， 此时过滤 装置 （2) 所在平面则与鼻前庭横截面 （12) (参考图 5) 保持倾斜姿态， 利用斜 截面的面积大于横截面的原理， 过滤装置 （2) 较传统鼻罩的过滤装置 （所在平 面处在鼻前庭的横截面上） 获得了更大的透气面积。
在图 3中， 过滤器（9)的边缘从边框（8) 内侧***边框（8) 内部， 边框（8) 包裹并粘合住过滤器（9) 的边缘， 二者牢固连接使整个过滤装置（2)集成为一 体化的组件。 插头 （3) 包含帽 （5)、 杆 （6)、 垫 （7) 三部分， 插头 （3) *** 边框 （8) 上的插孔 （10)， 插孔 （10) 套住杆 （6) 部， 帽 （5) 和垫 （7) 分别 卡在边框 （8) 的两侧， 从而实现鼻罩的连接。
在图 4中， 过滤器 （9) 周长大于边框 （8) 剖面的内圈周长但小于其外圈周 长， 这样过滤器 （9) 的边缘可镶嵌于边框 （8) 内。 另外， 在过滤装置 （2) 与 连接装置 （1) 相插接的部位， 杆（6) 与插孔（10) 的横截面完全吻合， 由于此 横截面的形状不为圆形， 因此可以防止过滤装置 （2) 绕插头 （3) 发生旋转。
在图 5中， 在本实施例中， 鼻罩***鼻前庭 （14) 后， 利用梁 （4) 的弹性使 两个过滤装置 （2) 的边框 （8) 向鼻中隔 （13) 方向夹紧， 实现鼻罩的固定。 此 时边框 （8) 贴紧鼻前庭 （14) 的内壁， 可以防止侧漏。 ***鼻前庭 （14) 后， 鼻罩大部分隐藏于鼻前庭 （14) 内， 只有梁 （4) 的一部分露在鼻外， 无损鼻部 的美观。鼻罩***深度不超过 15mm， 以防刺激鼻腔内壁（15)的敏感部位。同时， 梁 （4) 所在平面平行于鼻前庭中轴线 （11)， 过滤装置 （2) 所在平面倾斜于鼻 前庭横截面 （12) (即夹角为锐角）， 过滤装置 （2) 所在平面是鼻前庭 （14) 的 一个斜截面， 此斜截面的面积大于同一位置垂直于鼻前庭中轴线（11 )的鼻前庭 横截面 （12 ) 的面积 （以往鼻罩的过滤装置所在平面处于鼻前庭的横截面上）， 从而获得了更大的过滤面积， 提升了鼻罩的透气性， 使呼吸更加顺畅。
以下是对实施例的使用状态进行说明。
本鼻罩可根据滤除空气中微粒、 游泳用、 缓释药物以实现治疗功能等不同使 用目的， 将不同种类的过滤装置安装在插头 （3) 上。 例如， 为防花粉、 尘埃、 臭气粒子、细菌或病毒等目的，可使用具有滤除空气中微小颗粒功能的过滤装置。 在水中活动时， 为了防止水进入鼻腔 （15)， 可使用不透水的过滤装置。 用于缓 释药物实现治疗功能时，可使用能够浸渍缓释挥发性药剂或携带有稀释药剂效果 的微胶囊的过滤装置。使用者在外出时携带上述多个过滤装置， 则可根据需要有 选择的使用。
