Description

吸收罐旁路装置
技术领域
本发明涉及一种回路装置， 更具体的， 涉及一种回路中更换吸收罐时气 路的控制技术及其相应的机械结构。 背景技术
现有技术解决回路中更换吸收罐时气路的控制技术是纯机械式的， 主要 有两种方式，一种是在需要更换吸收罐时，通过转换气路的开关将气路切换， 然后取下吸收罐， 另一种是利用旁通阀原理， 进行气路的切换。 手术中直接 通过气动开关， 转换气路， 有的是等手术结束后， 进行更换。 由于是手动操 作开关， 操作不是很简便。
第一种解决回路中更换吸收罐时气路的控制技术原理是通过附图 8A中 的手动换向阀实现的， 在正常工作状态时， 手动换向阀处于 1位置， 病人呼 出的气体流入吸收罐， 当需要更换吸收罐时， 将手动换向阀拧到 2位置， 此 时病人呼出的气体将不通过吸收罐， 而直接流入吸收回路中。 此种方式由于 是手动操作开关， 容易引起误操作， 即在拆吸收罐时， 忘记对手动换向阀的 操作， 导致气路暂时开路。
第二解决回路中更换吸收罐时气路的控制技术原理是通过附图 8B中两 个弹簧复位式的两位三通阀实现的， 在正常工作状态时， 吸收罐压缩弹簧， 两个两位三通阀处于 2位置， 此时病人呼出的气体流入吸收罐， 当需要更换 吸收罐时， 在吸收罐拆除的时候， 弹簧复位， 两个两位三通阀处于 1位置， 此时病人呼出的气体将不流入吸收罐而进入吸收回路。此种技术对吸收罐装 配时其上两个气道口与两个两位三通阀的之间的密封要求和同轴度高， 若装 配不好， 容易漏气。 发明内容
针对现有技术中的上述技术问题， 本发明的目的在于提供一种吸收罐旁 路装置， 使得吸收罐的更换过程操作简单、 有效， 气路密封效果好。 一种吸收罐旁路装置， 包括：

下面结合附图和具体实施例对本发明作进一步说明，但不作为对本发明 的限定。
图 1-2示出了吸收罐旁路装置的组成结构， 微动开关 18通过连接板 21 与触轮 22相连接， 当机器正常工作时， 吸收罐 20与支撑管 10处于附图 3 位置， 此时触轮 22与支撑管 10不接触， 病人呼出的气体经过单向阀， 然后 流入吸收罐 20, 经吸收罐净化后， 流入病人吸气端 （见附图 1 ) , 当操作者 需要更换吸收罐时， 通过转动手柄 16将凸轮 1旋转到附图 5位置， 此时吸 收罐 20下降， 支撑管 10下端与触轮 22接触， 微动开关 18受压就将电信号 发送到控制电路板， 控制电路板给电磁阀一个信号， 此时电磁阀失电， 两位 两位三通阀第 2路， 再到病人吸气端， 不再经过吸收罐 20 , 因此此时吸收罐 被旁路掉， 便于操作者进行更换。
将凸轮座 6通过螺钉固定到横梁 8上， 把左垫圈 5和右垫圈 14分别装 入凸轮 1的凹槽里， 将左轴承 3和右轴承 15分别以过盈方式装入凸轮座 6 上对应的孔中， 然后将手柄 16插入轴承中及凸轮 1相应的空中， 再将紧定 螺钉 17拧入凸轮 1中螺紋孔， 实现手柄的定位。
将滑套 7过盈装入横梁 8中 ,销轴 13过盈装入轴套 12 中 , 然后将销轴 13插入支撑管 10及滚轮 11相应的孔中， 再把支撑管 10插入滑套 7中， 最 后把限位销 9过盈插入横梁 8和滑套 7相应的孔中。
用螺钉将连接板 21和触轮 22与微动开关 18连接起来， 然后用两个内 六角圓柱头螺钉 Μ1.6 χ 6将微动开关 18与支板连接起来， 再用内六角圓柱 头螺钉 23将支板 19固定到凸轮座 6上面。
图 3-5示出了根据本发明的吸收罐旁路装置的工作过程。
在实际应用中， 当需要更换吸收罐 20时， 转动手柄 16从附图 3到附图
5位置，此时触轮 22受支撑管 10压力， 由微动开关 18将电信号发送到控制 电路板， 控制电路板使电磁阀断电， 从而控制两位三通阀第 2路开通， 第 1 路关闭， 这样病人呼出的气体就不经过吸收罐， 从而方便地将吸收罐换掉， 当更换好吸收罐后， 再转动手柄 16从附图 5到附图 3位置， 此时触轮 22与 支撑管 10脱离， 由微动开关 18将电信号发送到控制电路板， 控制电路板使 电磁阀得电， 从而控制两位三通阀第 1路开通， 第 2路关闭， 这样病人呼出 的气体就经过吸收罐 20, 恢复了正常运行。
可选的， 触轮 22和支撑管 10还可做成其它形式， 不只限于图中所示出 的形状， 例如触轮 22还可做成凸轮状、 球状等， 如图 6所示。
可选的， 本发明中的旁路结构也可以应用于其它需要旁路的产品、 系统 或者技术领域内。
以上所述仅为本发明的优选实施例， 以上实施例仅用于对本发明的技术 方案和发明构思做说明而非限制本发明的权利要求范围。凡本技术领域中技 术人员在本专利的发明构思基础上结合现有技术， 通过逻辑分析、 推理或有 限实验可以得到的其他技术方案，也应该被认为落在本发明的权利要求保护 范围之内。
