[0059] 实施例二：
[0060] 本实用新型的便于给围术期病人雾化治疗的新型雾化给药设备的供气装置 3还 可以是普通的辅助空气呼吸机或者治疗用空气呼吸机， 在将给药装置 4的进气口 411与供气装置 3的供气端口 31相连通的第一进气管 42内设有富氧过滤装置 9。 富 氧过滤装置 9用于将空气呼吸机输出的空气进行过滤， 并使氧气在呼气通道内达 到有效富集的效果， 为雾化给药系统提供洁净、 较空气中氧气浓度高的可供围 术期病人呼吸的气体。
[0061] 如图 1至图 3所示， 富氧过滤装置 9包括套筒 91、 气体分流盘 92、 富氧管 93、 吸 氧膜 94、 隔网膜 95和空滤网 96， 其中：
[0062] 套筒 91在第一进气管 42内呈横向设置， 其左右两端呈幵口设置， 套筒 91的内腔 为圆柱体， 套筒 91的外壁与第一进气管 42的内壁呈气密封设置； 气体分流盘 92 为纵向设置的圆盘， 气体分流盘 92的中间设置有定位孔 921和数个排放孔 922， 定位孔 921位于气体分流盘 92的中心位置， 所有排放孔 922以定位孔 921为中心呈 圆形等间隔分布， 气体分流盘 92安装在套筒 91的出风口位置 (右端)； 富氧管 93呈 横向设置， 其为左端封闭、 右端幵口的管件， 富氧管 3安装在气体分流盘 92的定 位孔 921上， 富氧管 93的左端伸入到套筒 91的内腔内， 富氧管 93的中心轴线与套 筒 91的中心轴线重合， 位于套筒 91内腔中的一段富氧管 93为其吸氧部分， 该吸 氧部分的管壁上设置有数个输氧孔 931， 所有输氧孔 931呈等间隔均匀分布， 富 氧管 93吸氧部分的内壁设置有磁性材料， 富氧管 93的内腔为圆柱体； 吸氧膜 94 为对氧具有高吸附性及高渗透性的含钡的高分子聚合物， 该高分子聚合物以膜 的形式存在， 含钡的高分子聚合物即是利用钡的高活泼性进行富氧及利用高分 子聚合物对不同物质有选择性渗透的原理性能， 而采用对氧具有高吸附及高渗 透性能的含钡的高分子聚合物制作成吸氧膜 94， 吸氧膜 94包覆住富氧管 93的吸 氧部分的管壁， 且完全覆盖住所有的输氧孔 931， 利用吸氧膜 94使得先过渡的氧 分子被吸附到富氧管 93的管壁上， 而空气中的氮分子及其他气体分子被搁浅在 吸氧膜 94外； 隔网膜 95包覆在吸氧膜 94的外表面， 隔网膜 95可以起到缓冲、 透 气的作用， 以便被搁浅在吸氧膜 94外的氮分子及其他气体分子从隔网膜 95流出 ， 经排放孔 922排放。
[0063] 另外， 本实施例的吸氧膜 94和隔网膜 95可以采用多层复合的结构， 即多层吸 氧膜 94与多层隔网膜 95分层间隔排列整齐， 空气从最外层的隔网膜 95流入到富 氧管 93， 贫氧空气从最外层的隔网膜 95流出排放， 空滤网 96， 吸氧膜 94和隔网 膜 95的数量可按照实际氧浓度的需要配置。
[0064] 空滤网 96设置在套筒 91的内腔中， 且位于隔网膜 95与风机之间， 空滤网 96采用 通用的过滤材料制成， 以在隔网膜 7之前形成一道屏障， 用于过滤空气里的灰尘 及水汽。
[0065] 富氧过滤装置 9的氧氮分离方法与原理： 利用含钡的高分子聚合物的原理性 能制作成吸氧膜进行富氧， 并结合顺磁导向技术进行导氧输送， 来实现氧氮分 离。 所谓含钡的高分子聚合物即是利用钡的高活泼性进行富氧及利用高分子聚 合物对不同物质有选择性渗透的原理性能。 常规空气由空气呼吸机输送空气而 进入套筒 91的内腔， 吸氧膜 94所处的位置 (吸氧膜 94外包裹住富氧管 93的吸氧部 分)相对于富氧管 93的右端处于高压侧， 富氧管 93的右端因为处于低压侧， 进入 气套筒 91的内腔中的空气受压强影响， 空气中的氧和氮在压力差的驱动下透过 吸氧膜 94， 由于吸氧膜 94有选择地让氧分子比氮分子透过率大， 结果在吸氧膜 9 4低压一侧收集到的空气中氧气浓度增加， 富氧空气通过富氧管 93左端的输氧孔 931进入富氧管 93内， 并最终由富氧管 93的右端排出， 贫氧空气穿过隔网膜 95流 出， 并经由排放孔 922排放。
[0066] 在本实施例中， 所谓顺磁导向技术即该富氧管 93的吸氧部分内嵌磁性材料， 以便在富氧管 93的吸氧部分的管件内形成强磁力线， 利用空气中氧、 氮等气体 分子磁性特点的不同一氮等其他气体分子为抗磁性物质， 氧分子是顺磁性物 质， 氧分子具有较高的磁化率， 能在磁场中向强磁区流动的物理特性， 当空气 通过具有强磁场的富氧管 93吋只有顺磁性的氧分子被吸附进管内， 通过输氧孔 9 31输送至富氧管 93的幵口端， 进而通过第一管道 42输送到呼吸给药系统。
[0067] 本实施例通过在给药装置 4的进气口 411与供气装置 3的供气端口 31相连通的第 一进气管 42内设有富氧过滤装置 9， 通过富氧管 93和气体分流盘 92上分别设置有 输氧孔 931和数个排放孔 922， 把分离后的空气分流放送， 并通过吸氧膜 94和隔 网膜 95分层间隔排列来更进一步地提高富集氧的效率， 还能通过在套筒 91内腔 设置空滤网 96， 以使得富氧过滤装置 9为雾化给药系统提供洁净、 较空气中氧气 浓度高的可供围术期病人呼吸的气体。
[0068] 以上所述仅为本发明的较佳实施方式， 本发明并不局限于上述实施方式， 在实 施过程中可能存在局部微小的结构改动， 如果对本发明的各种改动或变型不脱 离本发明的精神和范围， 且属于本发明的权利要求和等同技术范围之内， 则本 发明也意图包含这些改动和变型。
