在一些实施方式中，麻醉通气系统包括麻醉机主机，蒸发器连接座110、进气接口120、出气接口130均位于该麻醉机主机。
在一些实施方式中，如图1所示，麻醉通气系统还包括麻醉蒸发器200。在另一些实施中，麻醉通气系统也可以不包括麻醉蒸发器200。麻醉蒸发器200能够和蒸发器连接座110可拆卸连接。
其中，麻醉通气系统的进气接口120和出气接口130，设于新鲜气体支路上，在麻醉蒸发器200连接到蒸发器连接座110时与麻醉蒸发器200连接。
具体的，如图2和图3所示，麻醉通气系统还包括在位检测装置141和控制器142，在位检测装置141可以连接于控制器142。
其中，在位检测装置141用于检测麻醉蒸发器200是否连接到蒸发器连接座110。示例性的，在位检测装置141在检测到麻醉蒸发器200连接到蒸发器连接座110时，向控制器142发送相应的信息，以通知控制器142麻醉蒸发器 200连接到蒸发器连接座110。
示例性的，控制器142在根据在位检测装置141检测到麻醉蒸发器200连接到蒸发器连接座110时，能够通过进气接口120向麻醉蒸发器200供气，通过出气接口130接收麻醉蒸发器200输出的麻醉气体；如果未检测到麻醉蒸发器200连接到蒸发器连接座110时，可以不向麻醉蒸发器200供气。从而可以防止气体泄漏。
示例性的，若控制器142获取到操作人员输入的开始通气指令，可以先通过在位检测装置141检测麻醉蒸发器200是否在位，只有在检测到麻醉蒸发器200在位，才通过进气接口120向麻醉蒸发器200供气，通过出气接口130接收麻醉蒸发器200输出的麻醉气体；若控制器142获取到操作人员输入的停止通气指令或者生成停止通气指令，则可以停止向麻醉蒸发器200供气。
在一些实施方式中，如图3和图4所示，麻醉蒸发器200包括设有第一电接口220的主体210和连接于第一电接口220的蒸发器电路230。
示例性的，蒸发器电路230可以控制麻醉蒸发器200的麻醉剂的喷射，和/或检测气体压力等过程。

在一些实施方式中，如图3和图4所示，麻醉通气系统还包括第二电接口150。麻醉蒸发器200连接到蒸发器连接座110时，第二电接口150和麻醉蒸发器200的第一电接口220连接。从而，第二电接口150可以通过第一电接口220向麻醉蒸发器200供电，以及和麻醉蒸发器200进行通信。此时，控制器142通过在位检测装置141检测麻醉蒸发器200在位，激活麻醉蒸发器，控制器142控制给第二电接口150上电，即通过第二电接口150和第一电接口200向麻醉蒸发器200供电，控制器142控制新鲜气体支路通过进气接口向麻醉蒸发器供气。当然，在位检测装置141检测到麻醉蒸发器200在位后，控制器142还可以控制先给第二电接口150上电，通过第二电接口150和第一电接口200向麻醉蒸发器200供电。控制器142在接收到供应麻醉控制信号后，才控制新鲜气体支路通过进气接口向麻醉蒸发器供气。
可以理解的，第一电接口220、第二电接口150例如包括多个电连接点，其中部分用于输送电能，另一部分用于进行通信。
在一些实施方式中，如图3和图4所示，在位检测装置141连接于第二电接口150。
示例性的，第二电接口150的至少一个电连接点连接于在位检测装置141。
可以理解的，第一电接口220或第二电接口150可以各自包括一个或多个接口，例如同一个接口的不同点连接点可以分别用于实现供电、通信、在位检测等功能，或者多个接口分别用于实现供电、通信、在位检测等功能。
示例性的，麻醉蒸发器200连接到蒸发器连接座110时，在位检测装置141可以通过第二电接口150连接到第一电接口220，以连接于麻醉蒸发器200的蒸发器电路230。
在一些实施方式中，如果在位检测装置141可以检测到蒸发器电路230，则可以判定麻醉蒸发器200连接到蒸发器连接座110。当在位检测装置141检测不到蒸发器电路230时，判定麻醉蒸发器200未连接到蒸发器连接座110。
示例性的，控制器142在根据在位检测装置141检测到麻醉蒸发器200的蒸发器电路230时，可以通过第二电接口150向麻醉蒸发器200供电；在未检测到麻醉蒸发器200连接到蒸发器连接座110时，则可以不向第二电接口150供电。
示例性的，麻醉蒸发器200获取供电之后，蒸发器电路230可以通过第一电接口220、第二电接口150与麻醉通气系统的控制器142进行通信。
示例性的，控制器142在根据在位检测装置141检测到麻醉蒸发器200连接到蒸发器连接座110时，能够通过进气接口120向麻醉蒸发器200供气，通过出气接口130接收麻醉蒸发器200输出的麻醉气体。
在另一些实施方式中，当麻醉蒸发器200连接到蒸发器连接座110时，在位检测装置141可以检测到蒸发器电路230的一种状态，则控制器142可以判定麻醉蒸发器200连接到蒸发器连接座110；当麻醉蒸发器200部分连接到蒸发器连接座110时，在位检测装置141可以检测到蒸发器电路230的另一种状态。当麻醉蒸发器200未连接到蒸发器连接座110时，在位检测装置141检测不到蒸发器电路230，则控制器142可以判定麻醉蒸发器200未连接到蒸发器连接座110。
示例性的，麻醉蒸发器200部分连接到蒸发器连接座110，包括：虽然第二电接口150和麻醉蒸发器200的第一电接口220连接，但是进气接口120和 出气接口130还未稳定、彻底的连接到麻醉蒸发器200。从而此时新鲜气体甚至麻药气体还存在泄漏的风险。
示例性的，如果控制器142通过在位检测装置141检测到蒸发器电路230的该另一种状态，则可以判定麻醉蒸发器200未连接到蒸发器连接座110。

示例性的，如图3至图5所示，解锁装置212包括设于抓握结构211的按压部2121，锁紧件240可以抵接于按压部2121。操作人员抓住抓握结构211时，能够作用于按压部2121使之带动锁紧件240转动。

当然，解锁装置212还可以包括一接收解锁命令的实体按键和/或虚拟按键，例如，通过一解锁按键或触摸屏上的虚拟按键接收解锁命令。或者，解锁命令也可以有控制器142发出，例如，在需要关闭麻醉通气系统、麻醉蒸发器，或接收到用户输入的解锁控制信息时，控制器142向解锁装置212发送解锁命令。解锁装置212接收到解锁命令后，将麻醉蒸发器200与蒸发器连接座110之间的锁合关系解锁。解锁装置212的各个组件可以根据需要分散设置在麻醉蒸发器200、蒸发器连接座110和麻醉机主机上。
在一些实施方式中，在将麻醉蒸发器200安装到蒸发器连接座110上时，，配合状态检测件231处于第二状态；在将麻醉蒸发器200继续向蒸发器连接座110的方向移动时，第一电接口220和第二电接口150先连接，然后进气接口120、出气接口130和麻醉蒸发器200连接密封，之后锁合端241落入锁钩槽162，配合状态检测件231处于第一状态，接下来蒸发器连接座110向麻醉蒸发器200输出供电。示例性的，锁合端241落入锁钩槽162后，麻醉蒸发器200可以继续向蒸发器连接座110的方向移动预设的距离，作为余量；当停止推动麻醉蒸发器200时，麻醉蒸发器200可以适当退回，但进气接口120、出气接口130和麻醉蒸发器200的连接、第一电接口220和第二电接口150的连接仍然稳定、可靠。
示例性的，如图6所示是在将麻醉蒸发器200安装到蒸发器连接座110上时，锁紧件240和配合件160相对位置关系的示意图，其中A至H为锁紧件240的锁合端241在配合件160上的不同位置。
在位置A处麻醉蒸发器200未连接到蒸发器连接座110时，第一电接口220、第二电接口150未连接，在位检测装置141未检测到麻醉蒸发器200的蒸发器电路230，第二电接口150不输出电能。
在位置B处，锁合端241沿斜坡向配合件160的端面161爬升，当锁合端 241爬升到位置C处的端面161时，配合状态检测件231处于第二状态。在锁合端241沿着端面161前进时，在位置D处第一电接口220和第二电接口150连接，控制器142通过在位检测装置141检测到配合状态检测件231处于第二状态，则第二电接口150不输出电能；然后在位置E处进气接口120、出气接口130和麻醉蒸发器200连接密封。当锁合端241在位置F和位置G处落入锁钩槽162，配合状态检测件231处于第一状态，控制器142通过在位检测装置141检测到配合状态检测件231处于第一状态，则蒸发器连接座110向麻醉蒸发器200输出供电。位置G和位置H之间为余量退回的行程。
当操作人员把麻醉蒸发器200从蒸发器连接座110移出时，操作人员抓住抓握结构211，使锁紧件240的锁合端241从锁钩槽162抬起，同时使得控制器142通过在位检测装置141检测到配合状态检测件231处于第二状态，则第二电接口150断开向麻醉蒸发器200的供电。锁紧件240的锁合端241从锁钩槽162抬起后，麻醉蒸发器200才能从蒸发器连接座110移出，移出过程中，配合状态检测件231一直处于第二状态，不给麻醉蒸发器200上电。因此也确保了移出过程中的安全。
通过对锁紧件240的锁合端241、配合状态检测件231、锁钩槽162、电、气接口等的位置排布，有效可靠地实现了麻醉蒸发器200先锁定，气路接口密封后，蒸发器连接座110才给麻醉蒸发器200上电，实现安全可靠的插拔。
进一步地，麻醉通气系统还可以包括设于蒸发器连接座110或麻醉蒸发器200上的锁合结构，控制器142检测到麻醉蒸发器200连接到蒸发器连接座110，控制锁合结构将麻醉蒸发器200锁紧在蒸发器连接座110上。在一些实施方式中，如图1、图7至图10所示，蒸发器连接座110还包括锁合结构180。控制器142检测到麻醉蒸发器200连接到蒸发器连接座110时，控制锁合结构180锁合麻醉蒸发器200。
示例性的，锁合结构180可以包括能够伸缩运动的锁合件181。控制器142能够控制锁合件181伸入麻醉蒸发器200的底部，以限制麻醉蒸发器200相对蒸发器连接座110的移动。
在一些实施方式中，锁合结构180锁合麻醉蒸发器200，具体为：锁合结构180锁合锁紧件240和配合件160的相互配合，限制锁紧件240相对配合件160移动，使麻醉蒸发器200与蒸发器连接座110锁合。
示例性的，锁合结构180压合于锁紧件240可以限制锁紧件240相对配合件160移动。
示例性的，锁合结构180能够作用于锁紧件240以限制锁紧件240的转动，从而操作人员抓住抓握结构211时，锁紧件240的转动被限制，所以锁紧件240和配合件160的相互配合能够被锁定在锁合的状态。操作人员无法按动按压部2121进行解锁，有效避免误操作，同时可以提醒操作人员此时麻醉蒸发器200处于工作状态。
示例性的，如图7和图8所示，锁合结构180包括能够运动的锁合件181，锁合件181例如可以沿水平方向或竖直方向运动。控制器142能够控制锁合件181运动以抵接于锁紧件240，限制锁紧件240的转动。具体的，锁合结构180启动后，锁合件181朝靠近锁紧件240的方向运动，锁合件181的端部能够压合于锁紧件240，实现对麻醉蒸发器200的锁合。
当然，锁合结构180还可以部分设于蒸发器连接座110上，另一部分设于麻醉蒸发器200上。
在一些实施方式中，如图9和图10所示，麻醉蒸发器200还可以包括设于主体210的压紧件250，压紧件250与主体210活动连接；锁合结构180能够推动压紧件250，使得压紧件250压合于锁紧件240的锁合端241，以限制配合件160的转动。
示例性的，麻醉蒸发器200还可以包括与压紧件250连接的复位元件(未图示)。如图9所示，压紧件250与主体210转动连接，复位元件与主体210固定连接。具体的，锁合结构180可以带动压紧件250转动，使得压紧件250压合锁紧件240于配合件160。
示例性的，主体210的底部形成有安装槽，该压紧件250可以容纳于上述安装槽内，并转动连接于安装槽的侧壁。锁合结构180启动后，朝向麻醉蒸发器200运动，推动压紧件250转动至水平位置时，压紧件250压合于锁合端241。可以理解的，作为本实施例的一种替代方案，锁合结构180带动压紧件250转动，使得压紧件250压合于配合件160，也可以实现通过锁合结构180锁合麻醉蒸发器200。
示例性的，压紧件250可与主体210滑动连接。如图10所示，主体210底部形成有安装槽，该压紧件250容纳于上述安装槽内，并滑动连接于安装槽 的底壁，锁合结构180启动后，沿垂直方向运动，推动压紧件250朝靠近锁紧件240的方向运动，直至压紧件250压合于锁合端241。可以理解的，作为本实施例的一种替代方案，锁合结构180可以推动压紧件250压合于配合件160，也可以实现通过锁合结构180锁合麻醉蒸发器200。
在一些实施方式中，锁合结构180可以为气控装置；在另一些实施方式中，锁合结构180可以为电控装置。
示例性的，锁合结构180根据控制器142的控制锁合或释放麻醉蒸发器200。例如，锁合结构180根据控制器142的控制，锁合或解锁锁紧件240和配合件160的相互配合。
示例性的，控制器142能够控制锁合结构180启动，以推动压紧件250压合于锁紧件240或配合件160，实现锁合麻醉蒸发器200。示例性的，控制器142能够控制锁合结构180关闭，以释放压紧件250对锁紧件240或配合件160的压合。
示例性的，在将麻醉蒸发器200在蒸发器连接座110上安装到位后，锁合件181的锁合端241与配合件160卡合，锁合件181和配合件160实现第一重锁合。例如通过蒸发器连接座110向麻醉蒸发器200供电使得麻醉蒸发器200被激活，同时可以启动锁合结构180，以进一步锁合麻醉蒸发器200，实现双重锁合。当麻醉蒸发器200处于激活状态，例如从进气接口120获取气体和向出气接口130输出麻醉气体时，锁合结构180保持对麻醉蒸发器200的锁合，从而可以避免由于操作人员误操作而导致麻醉蒸发器200脱离蒸发器连接座110。
示例性的，当需要将麻醉蒸发器200拆除时，控制器142控制麻醉蒸发器200停止工作，还可以向锁合结构180发出关闭信号，释放对锁紧件240的限制，例如压紧件250可以在复位元件的作用下向远离锁紧件240的方向运动，松开锁紧件240的锁合端241；通过按动按压部2121，带动锁紧件240转动，使得锁合端241与配合件160脱离，可将麻醉蒸发器200从蒸发器连接座110上拆卸，通过单手操作即可解锁，方便快捷。
