本发明提供的一种氧气吸入器， 其特征在于： 包括上述的湿化瓶， 以及与 湿化瓶相连接的氧气吸入器主体， 湿化瓶内装有湿化液， 所述氧气吸入器主 体上设有与气源相连接的气源快速插头， 所述气源快速插头与气源上相适应 的快速接头连通。
本发明改进了湿化瓶进氧导管的结构和连接方式。进氧导管、移动滑体和 启闭器配合组成的进气通道的密封装置， 不仅有氧气通过的功能， 还有密封湿 化液的功能， 密封装置未启动时密闭了进气通道， 使湿化瓶中的湿化液在正常 储存下处于密封状态， 不会泄漏， 保证了湿化液的安全存放。 当湿化瓶正常使 用时， 密封装置自动打开， 气体便通过进氧导管进入湿化瓶进行湿润， 湿润过 的氧气便通过进氧导管上的气孔进入出气通道经吸氧管输送给病人。对进氧导 管结构的改进还使得湿化瓶出气通道在正常储存时也处于密封状态， 与出气通 道相连接的吸氧管也就同时处于密封状态， 保证了湿化液的安全存放。
另外， 本发明还改进了现有的一次性吸氧管的连接结构和连接方式。 将 吸氧管预先安装在湿化瓶体上， 医护人员在使用湿化瓶时不需再连接安装一次 性使用吸氧管， 这样就减少了安装一次性使用吸氧管的工作步骤， 减轻了医护 人员的工作量， 节约了安装时间。 .
本发明提供的氧气吸入器， 其湿化瓶的进氧导管内置并密封连接， 其移动 滑体位于和湿化瓶体密封相连的快速接头中的适当位置，通过湿化瓶和氧气吸 入器主体相连卡接时产生的推压力来同时启动湿化瓶的进出气通道（即密封装 置）。 这种氧气吸入器结构简单， 操作便利， 即防止了交叉感染又节省了安装 时间， 且安全可靠。
另外， 本发明提供的氧气吸入器， 还改进了氧气吸入器主体和湿化瓶的连 接方式， 把现有的螺纹连接方式改进为快速接头的连接方式， 极大地提高了湿 化瓶和氧气吸入器主体的连接与拆卸速度， 并能实现准确连接， 缩短了医护人 员为病人输氧的准备时间， 减轻了医护人员的工作强度和工作量， 提高了工作 效率。

具体实施方式
如附图 1〜5所示为可一次性使用的湿化瓶， 包括湿化瓶体 5, 湿化瓶上 带有进气通道和出气通道 51， 湿化瓶体 5的瓶口处设有进氧导管 3和移动滑 体 31 ; 进氧导管 3至少包括带有大直径的与瓶口密封连接的上导管 3a 和小直径的伸入湿化瓶内的下导管 3b。 移动滑体 31的截面呈倒 T形， 移 动滑体 31的底部设有梯形沉台 31b， 进氧导管 3的上导管 3a与下导管 3b的 过渡处设有与梯形沉台 31b相配合的锥面 3d。移动滑体 31的下段外壁与上 导管 3a内壁密封配合， 上导管 3a的壁上设有多个气孔 3c; 这些气孔 3c 所设置的高度位置应当满足当外力向下推动移动滑体 31到一定程度时候， 气孔 3c外露； 当移动滑体处于自然状态时（即无外力推动状态） ， 气孔 3c 被移动滑体 31封闭。 在移动滑体 31中心设有通孔 31a， 通孔 31a内设有在 外力向下推动移动滑体 31状态下打开进气通道 32a、 自然状态下密封进气通 道 32a的密封装置； 湿化瓶体 5的出气通道 51上密封设置有吸氧管 4， 出气 通道 51和湿化瓶体 5内进氧导管的上导管 3a壁上的其中一个气孔 3c相连接。 上述封闭装置还可以包括带轴肩 32b的启闭器 32 (当然也可以是启闭 器 32与移动滑体 31—体或通过螺紋连接成一体） 。 启闭器 32的轴肩 32b与 启闭器 32—体制成， 或单独作出连接在启闭器 32上。 启闭器 32的轴肩 32b 以上部分伸入到移动滑体 31的通孔 31a内，轴肩 32b顶置在移动滑体 31底部 的梯形沉台 31b处， 与移动滑体 31保持密封接触。启闭器 32的下端伸入下导 管 3b内， 启闭器 32的中心设有气路 32c，此时气路 32c成为湿化瓶的进气通 道 32a， 气路 32c内套设有气路密封连杆 33， 气路密封连杆 33可以为如附 图 4a所示的空心管， 该空心管的壁上设有气孔 33b， 气路密封连杆 33的 上端设有气路密封锥体 33a, 气路密封连杆 33上套设有弹簧 36， 弹簧 36的一 端顶设在启闭器 32的下端， 并将启闭器 32的轴肩 32b顶在移动滑体 31下部 的梯形沉台 31b处， 使启闭器 32与移动滑体 31保持密封关系。 弹簧 36的另 一端直接或间接定位在下导管 3b的底部。本实施例中， 弹簧 36的另一端定位 在气路密封连杆 33的下端， 使气路密封锥体 33a保持压紧进气通道 32c的进 气口 32a。 另外， 气路密封连杆 33也可以采用如附图 4a所示的结构： 即 气路密封连杆 33由实心的上连杆和空心的下连杆卡接构成； 下连杆的壁 上设有与启闭器的气路相连通的气孔 33b， 下连杆的下端设有可套设并顶 置弹簧的平台。
下导管 3b的底部连接或直接设置有延伸管 35， 延伸管 35的上端与气路 密封连杆 33内部相连通， 延伸管 35的下部伸入到湿化瓶体 5的底部。 或者， 延伸管 35也可与气路密封连杆 33做成一体。 湿化瓶体 5内事先装设湿化液， 湿化瓶未使用状态下， 延伸管 35伸入到湿化瓶体 5底部的湿化液内。 当然， 本发明也可以这样使用： 进氧导管 3与湿化瓶体 5密封连接， 在需要时， 拔下 进氧导管加入湿化液后， 再将进氧导管与湿化瓶密封连接。
在湿化瓶未被使用情况下（即自然状态下）， 启闭器 32在弹簧 36的作用 下压紧气路密封锥体 33a，从而对进气通道 32a进行密封。同时启闭器 32的轴 肩 32b也在弹簧 36的作用下顶住移动滑体 31，使得移动滑体 31在进氧导管 3 中保持在适当的位置，并密封进氧导管 3上的气孔 3c, 同时密封了与其中一个 或部分气孔 3c相连通的吸氧管 4。这种情况下，装设在湿化瓶体 5内的湿化液 处于被密封的状态， 不会造成泄漏。 因此可以实现在湿化瓶体 5内事先装入湿 化液， 从而可以简化吸氧的准备步骤， 同时还可以实现一次性使用。
附图 6显示了本发明用于与上述湿化瓶连接的氧气吸入器主体的结构示 意图。 其包括氧气吸入器主体主体 10、 流量调节旋钮 6、 气源快速插头 8、 与湿化瓶体 5连接的快速插头 1。 其中气源快速插头 8用于与气源上相适应 的快速接头连通。 流量调节旋钮 6调节并控制氧气流量。 快速插头 1的上端 设有外螺纹 la， 用于与氧气吸入器主体主体 10上的螺紋连接成一体。 快速 插头 1下端的周壁上设有密封环 9及卡接环槽 lc。 同时， 快速插头 1中心设 有连通氧气吸入器主体主体 10内部与湿化瓶的进气通道 32a的通道 ld。
同时，在湿化瓶体 5的瓶口处设置有快速接头 2，快速接头 2可以与进氧 导管 3连接成一个整体。 其中移动滑体 31的上端面距离快速接头 2的上端面 的距离 L (如附图 1所示）需要小于氧气吸入器主体的快速插头 1插入快速接 头 2内的长度 S (如附图 7所示）。
附图 7为湿化瓶与氧气吸入器主体连接后的使用状态示意图。 如图所示，' 当湿化瓶体 5上的快速接头 2和氧气吸入器主体主体 10上快速插头 1连接接 合时产生的推压力推动移动滑体 31移动时， 便使湿化瓶的进、 出气系统同时 打开。 由于移动滑体 31与快速插头 1上端带有适当的距离 L, 当快速接头 2 与快速插头 1结合时， 使得快速插头 1下端顶推动移动滑体 31， 使移动滑体 31发生 (S— L)的位移。移动滑体 31下端的梯形沉台 31b推动启闭器 32上的轴 肩 32b下移，从而开启启闭器 32上气路 32c的进气通道 32a，使气路 32c打开。 氧气吸入器主体主体 10内的氧气经气路 32c及气路密封连杆 33上的气孔 33b 进入气路密封连杆 33内， 并经延伸管 35和消音器 34送入湿化瓶体 5内的湿 化液中进行湿化。 由于移动滑体 31被快速插头 1压下， 克服弹簧 36的作用力 下移， 因此进氧导管 3的上导管 3a上的多个气孔 3c露出， 经过湿化后的氧气 经过其中的部分气孔 3c进入进氧导管 3与移动滑体 31之间， 并经过与上导管 3a上的气孔 3c相连的出气通道 51输送给吸氧管 4， 供病人吸取。 图 7中箭头 所示即为氧气的流向。
以上的氧气吸入器主体利用了快速接头 2和快速插头 1的卡接结构， 主 要是为了操作的便捷性。 其中快速接头 2和快速插头 1的连接结构本身属于 现有的成熟技术， 因此不对其具体结构做详细描述。
另外，湿化瓶和氧气吸入器主体也可以不通过快速接头和快速插头连接， 而是通过螺紋连接， 例如在氧气吸入器主体上设置外螺纹。 因此， 只要氧气 吸入器主体连接在湿化瓶上后， 其外螺紋部分能推动移动滑体产生向下的位 移， 即可以实现湿化瓶的进、 出气系统同时打开， 也即可以实现本发明所要 解决的技术问题。
本发明结构简单，易于生产加工制造， 成本低， 便于推广使用。 所用原 料均为医用 PVE、 PE材料、 医用高分子材料，使用安全,无毒害。
另外，本发明采用了把一次性使用吸氧管和湿化瓶一体式设计制造的设计 理念,把一次性使用的吸氧管提前安装在湿化瓶体上，医护人员使用时，不用再 安装吸氧管,不减少了工作步骤，同时还防止了人为操作失误造成吸氧管漏气 等问题。
总的来说，本发明中进氧导管进出气系统的改进，使得进氧导管承担了密 封湿化瓶体内湿化液的功能，使得湿化瓶体内预先加入的湿化液处于密闭的保 存环境中， 不会泄漏， 不被外界污染， 因此医护人员在使用湿化瓶时就不用临 时向湿化瓶内加入湿化液， 这样就减少了操作步骤， 并能实现一次性使用。湿 化瓶预装了吸氧管及采用快速接头式的连接方式， 也减少了安装步骤，同时防 止人为操作失误。湿化瓶的一次性使用解决了输氧治疗和抢救中产生交叉感染 的问题。
