[0013] 图 2是本实用新型实施例提供的可密封检测的中分管组件中的第一接头的示意 图。
本发明的实施方式
[0014] 为了使本实用新型的目的、 技术方案及优点更加清楚明白， 以下结合附图及实 施例， 对本实用新型进行进一步详细说明。 应当理解， 此处所描述的具体实施 例仅仅用以解释本实用新型， 并不用于限定本实用新型。
[0015] 如图 1和图 2所示， 本实用新型实施例提供的一种可密封检测的中分管组件， 包 括用于与呼吸面罩连接的第一接头 11和用于与呼吸机连接的第二接头 12， 第一 接头 11和第二接头 12之间通过中分管 13连接， 中分管 13包括用于传输气体且可 折弯变形的管体 131， 管体 131内设有将管体 131的内部通道分隔为相互隔离第一 通道 132和第二通道 133的隔片 134， 第一接头 11的内腔中设置有将其内腔分隔为 相互隔离的两部分的隔板 14， 隔板 14上设置有用于与隔片 134连接的连接结构 14 1， 隔片 134的一端与连接结构 141连接。 通过这样的设置， 在实际生产装配吋， 第一接头 11的一端插入管体 131内， 并且使隔片 134的一端与连接结构 141连接。 这样， 隔板 14与隔片 134一起， 将整个管体 131的内部通道分隔成两个彼此隔离 的第一通道 132和第二通道 133， 用于输送不同的气体。 而由于第一通道 132和第 二通道 133内传输的气体不能发生混合， 因而， 隔片 134自身的密封性便决定着 能否可靠地输送气体。 进而， 在本实施例中， 通过在第一接头 11内设置有隔板 1 4， 并在其上设置有用于与隔片 134连接的连接结构 141， 使隔片 134与隔板 14连 接之后， 将第一通道 132和第二通道 133完全分隔。 实际检测吋， 在将第一接头 1 1堵住密封， 完成检测管体 131的密封性之后， 此吋便可以对隔片 134的密封性进 行检测。 检测堵头 2从第一接头 11插入， 和上下硬壁相接， 将第一通道 132或第 二通道 133堵住， 然后在第二接头 12上连接上呼吸机或麻醉机 3， 通过呼吸机或 麻醉机 3先往被密封的通道内通入一定压力的气体， 并保持一段吋间， 如果呼吸 机或麻醉机 3上的压力表 31的读数不变， 则表示隔片 134不漏气， 密封性好； 而 如果压力表 31的读数发生变化， 则表示隔片 134存在漏气， 不能使用。 通过这样 ， 能够进行隔片 134密封性检测， 筛选出漏气的隔片 134， 从而保证了中分管 13 组件使用的安全性。
[0016] 本实用新型实施例中提供的可密封检测的中分管 13组件， 通过在第一接头 11内 设置有隔板 14， 并通过在隔板 14上设置有连接结构 141， 连接结构 141与隔片 134 的一端连接， 从而使隔片 134将管体 131的内部通道分成两个相互隔离的通道。 这样， 通过密封堵住其中的一个通道， 从另一端通气， 便可实现对隔片 134的气 密性进行检测， 筛选出隔片 134存在漏气的中分管 13组件， 避免隔片 134存在漏 气的中分管 13组件被使用， 提高了使用的安全性。
[0017] 具体地， 如图 1和图 2所示， 连接结构 141为幵设在隔板 14上的连接凹槽， 连接 凹槽幵设的方向与隔板 14的长度方向相同， 隔片 134插设于连接凹槽内。 隔片 13 4与连接凹槽之间的连接方式为过盈配合。 并且， 隔片 134插设在连接凹槽内， 两者之间还设置有密封胶层， 确保连接处密封性和连接的稳定、 牢固性。
[0018] 具体地， 如图 1和图 2所示， 第一接头 11和第二接头 12用于与管体 131连接的一 端为连接端 111， 第一接头 11的另一端用于与呼吸面罩， 连接端 111插设于管体 1 31内， 隔板 14设置在连接端 111的内腔， 并且， 隔板 14将连接端 111的内腔分隔 为相等的两部分。 这样， 隔板 14将连接端 111的内腔均分为两等份， 以满足传输 气体的设计要求。
[0019] 具体地， 如图 1和图 2所示， 为保证中分管 13与第一接头 11之间连接的密封性， 防止发生漏气， 便在连接端 111上幵设有用于安装密封圈 112的密封槽 113。 在安 密封槽 113内安装有密封圈 112， 从而在将连接端 111插入至管体 131内吋， 通过 密封圈 112密封， 以保证密封的可靠性。
[0020] 具体地， 如图 1和图 2所示， 在使用的过程当中， 比如与呼吸面罩以及呼吸机连 接， 或者使用位置发生变动吋， 连接处会受到一定的外力而影响连接处的密封 性。 为了保证连接处密封的可靠性， 不发生漏气， 在第一接头 11与管体 131的连 接处以及第二接头 12与管体 131的连接处均分别设置有用于密封加固的密封包胶 层 114， 密封包胶层 114包覆于相对应的密封圈 112的外表面。 这样设置， 先通过 密封圈 112进行密封， 然后将橡胶或软胶通过注塑或者硫化方式设置在连接处的 缝隙内， 将第一接头 11与管体 131连接处之间的缝隙以及第二接头 12与管体 131 连接处之间的缝隙填充满， 并相互熔接粘连成为一体， 并与密封圈 112粘连， 从 而形成一个密封加固的密封包胶层 114， 这样保证了连接处的密封可靠性以及连 接强度， 能够承受一定强度的外力， 在承受外力吋不会发生松动， 保证了输气 的可靠性。
[0021] 优选地， 管体 131为波纹管， 其外表面橙皱褶状， 从而更加利于弯曲变形而不 易受损。
[0022] 以上所述仅为本实用新型的较佳实施例而已， 并不用以限制本实用新型， 凡在 本实用新型的精神和原则之内所作的任何修改、 等同替换或改进等， 均应包含 在本实用新型的保护范围之内。
