附图说明
下面将结合本发明的实施例及附图， 对本发明的上述和其他方面进行说 明， 这些内容会变得更为清晰。 图 1为流量控制器的结构示意图；
图 2为快速插头的结构示意图；
图 3为密封帽的结构示意图；
图 4为流量控制器主体、 快速插头、 密封帽组合的结构示意图； 图 5为湿化瓶体与快速接头、 进氧导管结合在一起的结构示意图； 图 6为本发明中流量控制器与湿化瓶卡接在一起的结构示意图。
具体实施方式
附图 1〜4显示了本发明用于快速连接的流量控制器的结构示意图。 其 包括流量控制器主体 10、 流量调节旋钮 6、 气源快速插头 8、 快速插头 1、 密封帽 11。 其中气源快速插头 8用于与气源连接， 流量调节旋钮 6调节并 控制氧气流量。 快速插头 1的上端为设有外螺纹的螺纹端 la， 用于与流量 控制器主体 10上的螺纹连接成一体。 快速插头 1的下端为与湿化瓶体 5相 连接的卡接端 lb， 卡接端 lb的周壁上设有密封环 9及卡接环槽 lc。 同时， 快速插头 1中心设有连通流量控制器主体 10内部与外界的通道 ld。当流量 控制器处于不使用的状态时， 可以在快速插头 1外套设一个密封帽 11， 用 于遮盖快速插头 1的通道， 防止被灰尘、 细菌等污染。
图 5为和本发明用于快速连接的湿化瓶的结构示意图。 其包括结合在 一起的湿化瓶体 5与快速接头 2、 进氧导管 3。 其中湿化瓶体 5上部的壁上 设有吸氧管接头 4， 用于连接一次性使用吸氧管 12， 供病人吸入被湿化后 的氧气。 快速接头 2被密封固定或螺纹连接在湿化瓶体 5的瓶口处， 快速 接头 2的下端与进氧导管 3—体密封连接或一体制成。 快速接头 2的上端 设有与快速插头 1尺寸相适配的沉台 2a，沉台 2a的内壁上设有与快速插头 1的卡接环槽 lc相嵌合的弹性卡珠或弹性卡簧 2b。 快速接头 2与进氧导管 3一体连接或一体制成，进氧导管 3的另一端伸向湿化瓶体 5的底部。快速 接头 2的中心也设有连通湿化瓶体 5内部与外界的通道 2c。该通道 2c与进 氧导管 3相连接或连通。因此，当需要向湿化瓶体 5内部加入湿化液 13时， 从快速接头 2经进氧导管 3注入即可。 同样， 为了防止湿化瓶体 5内部被 污染，快速接头 2上也可以设有封闭其通道 2c的密封帽或密封盖或密封塞。 其中， 注入的湿化液 13不应超出湿化瓶体 5二分之一的高度。
以上所述的快速接头 2和快速插头 1的具体结构仅仅是一种举例，也可 以是在快速插头 1上设置卡簧， 与快速接头 2上的卡勾相扣合， 因此， 上述 的实施例并不用于限制本发明的保护范围。 由于快速接头和快速插头的连接 结构本身属于现有的成熟技术， 因此凡是在氧气吸入器上使用到快速接头 2 或快速插头 1， 均应落入本发明的保护范围。
当需要使用氧气吸入器时， 如附图 6所示， 将加了湿化液的湿化瓶的快 速接头 2快速推入到流量控制器的快速插头 1中即可完成快速、 准确的卡接 (或者将快速插头 1快速插入快速接头 2中也可完成快速准确的卡接)， 采取 推入或插入主要看操作者的操作习惯， 两种使用方式都可以。 在推入或插入 过程中的瞬间， 操作者会听到快速接头中卡簧或卡珠发出轻微响声， 这表明 快速插头 1和快速接头 2在推入或插入中完成了连接， 快速插头 1和快速接 头 2的结合处于密封的锁定连接状态， 此时操作者便可以进行输氧的其它操 作步骤， 为病人进行输氧治疗和抢救。 输氧治疗和抢救结束后， 操作者抓住 快速接头 2稍微向下用力拨出， 即可让快速接头 2迅速脱离流量控制器，从而 实现快速拆卸。 然后根据相关管理规定， 妥善处理使用过的湿化瓶体 5。
本发明所用原料均为医用 PVE、 PE材料、 医用高分子材料,使用安全， 无毒害。
本发明结构简单，易于生产加工制造， 成本低， 便于推广使用。 对氧气吸入器的湿化瓶可以进行快速安装或拆卸，安装时轻微用力推入 (或插 入）即可，拆卸时向下拔出便行。 极大地节约了安装和拆卸时间， 同时改进了 进气导管的连接方式，减少了操作步骤，不但减轻了医护人员的劳动强度， 更 为病人输氧治疗和抢救节约了宝贵的等待时间。 快速插头式的连接装置任何 人都能正确使用，不会出现人为操作失误，从而达到快速准确连接和快速拆卸 的目的。
