Description

麻醉蒸发器和麻醉机 技术领域
本发明涉及医疗设备领域,特别涉及一种麻醉蒸发器和麻醉机。
背景技术
在喷射式麻醉蒸发器工作过程中需向储药腔内通入驱动气体,以对存储于储药腔内的麻醉剂施加一定的压力,使得麻醉剂由喷嘴呈雾状喷出,再与空气和氧气混合后进入病人体内。在上述喷射式麻醉蒸发器工作过程中,若需要向储药腔内添加麻醉剂,必须首先卸放储药腔内的压力,否则将盛装麻醉剂的罐体插入加药口时,大量麻醉剂会由加药口喷出,对操作人员造成危害。其中一种解决该问题的技术方案是在加药盖上设置传感器,利用传感器检测开盖动作,并向卸压电磁阀发出控制信号,实现开盖过程中自动卸压。然而该方案需要传感器和卸压电磁阀相互配合实现自动卸压,若传感器或卸压电磁阀其中之一出现故障即不能正常工作,安全性和可靠性较低。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步的详细说明。应当理解,此处所描述的具体实施方式仅仅用以解释本发明,并不限定本发明的保护范围。
请参阅图1和图2,一种麻醉蒸发器100,包括壳体10、盖体20、联动机构50、机械卸压组件40和储药池30,壳体10上设有一开口11,盖体20转动连接于壳体10的开口11处,储药池30、机械卸压组件40和联动机构50容纳于壳体10和盖体20围成的空间内,机械卸压组件40分别与外部的驱动气气源a、以及储药池30连通,同时与联动机构50连接,机械卸压组件40具有保持储药池30内压力的第一状态,和卸放储药池30内压力的第二状态,具体的,卸放储药池30内的压力是指排出储药池30内的气体,使得储药池30内的压强维持一较低值。加药过程中对麻醉蒸发器100操作的操作动作作为联动机构50的驱动力,能够使机械卸压组件40由第一状态切换至第二状态。
在第一实施例中,请参阅图1和图2,联动机构50为凸轮机构,凸轮机构一端连接于盖体20,另一端连接于机械卸压组件40的阀杆组件45,当需要添加麻醉剂时,盖体20打开的过程中,带动凸轮机构发生转动,随之推动阀杆组件45运动,进而使机械卸压组件40由第一状态切换至第二状态。由于凸轮机构与盖体20连接,在打开盖体20的过程中带动凸轮机构运动,实现机械卸压,该麻醉蒸发器100的安全性和可靠性更高。
具体的,凸轮机构包括凸轮51和转轴52,转轴52转动连接于壳体10,盖体20上固设有连接杆21,连接杆21固定连接于转轴52,凸轮51固定于转轴52上,阀杆组件45的末端滑动连接于凸轮51的边缘。机械卸压组件40包括主体44、第一管道41、第二管道42和第三管道43、及阀杆组件45,第一管道41、第二管道42和第三管道43均与主体44连通,第三管道43与 储药池30连通,阀杆组件45部分容纳于主体44,且阀杆组件45一端连接于主体44内壁,另一端连接于联动机构50,具体地,滑动连接于凸轮51的边缘。当盖体20打开时,通过连接杆21带动凸轮51相对壳体10转动,从而带动阀杆组件45发生运动。
第一管道41连接于驱动气气源a,第二管道42连接于废气处理系统b。
储药池30与机械卸压组件40连接,具体的,与机械卸压组件40的第三管道43连接。储药池30盛装有麻醉剂,其中,麻醉剂的液面高度低于机械卸压组件40与储药池30连接处的高度,能够避免麻醉剂由储药池30进入机械卸压组件40。
储药池30的顶部设有加药筒31,加药筒31与盖体20相对设置。当盖体20相对壳体10转动以打开壳体10的开口11时,加药筒31从该开口11处露出,方便操作人员通过该加药筒31对储药池30内进行加药的操作。该加药筒31内设置有密闭阀32,以实现对储药池30的密封,在一实施例中,该密闭阀32为单向阀。该密闭阀32设置为允许麻醉剂从加药筒31进入储药池30,而不允许麻醉剂从储药池30流出加药筒31。
储药池30还设置有液位计33,用于显示麻醉剂的液位高度。
请参阅图1,当麻醉蒸发器100正常工作,未进行加药操作时,阀杆组件45位于第一位置,机械卸压组件40处于第一状态,第一管道41和第三管道43连通,驱动气体经由第一管道41和第三管道43不断通入储药池30,以保持储药池30内的高压状态,使得麻醉剂经由连通于储药池30的喷嘴82喷出时呈雾状;请参阅图2,需要进行加药操作时,打开盖体20时,带动联动机构50运动,联动机构50推动阀杆组件45运动至第二位置,机械卸压组件40处于第二状态,第三管道43和第二管道42连通,驱动气体停止进入储药池30,同时,储药池30内的驱动气体经由第三管道43和第二管道42排出,实现储药池30的卸压。

请参阅图1和图2,麻醉蒸发器100还包括设于第三通道43的压力传感器60和开关阀70,开关阀70靠近储药池30设置。在麻醉蒸发器100处于工作状态时,需要进行加药时,通过联动机构50和机械卸压组件40的配合,机械卸压组件40由第一状态切换至第二状态,使得储药池30内部压力降低,储药池30和第三通道43连通,设于第三通道43的压力传感器60检测到储药池30中的驱动气体压力低至某一预设值时,控制开关阀70关闭,避免驱动气体持续排出,减少麻醉剂的损失;加药完成后,在联动机构50的推动下,阀杆组件45由第二位置移动至第一位置,第一通道41和第三通道43连通,驱动气体经由第一通道41进入第三通道43,压力传感器60检测到第三通道43内的驱动气体压力高至某一预设值时,控制开关阀70打开,驱动气体经由第一通道41和第三通道43进入储药池30,麻醉蒸发器100恢复正常工作状态,通过压力传感器60和开关阀70的设置使得整个系统在完成加药动作后自动激活,无需操作人员进行额外操作,大大简化了操作流程,使用方便,提升用户体验。
请参阅图1,麻醉蒸发器100还包括与储药池30底部连通的管道80和蒸发室90,管道80的末端设有喷嘴82,喷嘴82位于蒸发室90内,储药池30内的麻醉剂在高压驱动气体的作用下,由喷嘴82呈雾状喷射而形成麻醉剂气体,并充满蒸发室90内,蒸发室90设有进气口91和出气口92,载气由进气口91进入蒸发室90内,与麻醉剂气体混合后由出气口92排出。管道80上还设置有控制阀81,以控制储药池30与蒸发室90通断。
麻醉蒸发器100需要进行加药时,打开盖体20的动作,触发凸轮机构推动阀杆组件45运动,阀杆组件45由第一位置移动至第二位置,机械卸压组件40由第一状态切换至第二状态,驱动气体停止进入储药池30,相反的,储药池30内的驱动气体经由第三通道43和第一通道41排出,压力传感器60检测到储药池30内的压力降低至安全范围内,控制开关阀70关闭,操作人员操作加药容器200推开密闭阀32,从而加药容器200与储药池30内部连通,麻醉剂注入储药池30;完成加药后,操作人员关闭盖子20的动作触 发凸轮机构推动阀杆组件45运动,阀杆组件45由第二位置移动至第一位置,第一通道41和第三通道43连通,驱动气体经由第一通道41进入第三通道43,压力传感器60检测到第三通道43内的驱动气体压力高至某一预设值时,控制开关阀70打开,驱动气体经由第一通道41和第三通道43进入储药池30,麻醉蒸发器100恢复正常工作状态。
在第二实施例中,请参阅图3和图4,联动机构50为连杆机构,连杆机构一端转动连接于盖体20,另一端转动连接于阀杆组件45,盖体20绕一固定支点转动以打开的过程中,带动连杆机构运动,连杆机构进而推动阀杆组件45运动,阀杆组件45由第一位置移动到第二位置,第二通道42和第三通道43连通,储药池30内的高压驱动气体排出,实现卸压。由于连杆机构与盖体20连接,在打开盖体20的过程中带动连杆机构运动,进而实现机械卸压,该麻醉蒸发器100的安全性和可靠性更高。其他结构均与第一实施例相同,不再赘述。
麻醉蒸发器100需要进行加药时,打开盖体20的动作,触发连杆机构推动阀杆组件45运动,阀杆组件45由第一位置移动至第二位置,机械卸压组件40由第一状态切换至第二状态,驱动气体停止进入储药池30,相反的,储药池30内的驱动气体经由第三通道43和第一通道41排出,压力传感器60检测到储药池30内的压力降低至安全范围内,控制开关阀70关闭;完成加药后,操作人员关闭盖子20的动作触发连杆机构推动阀杆组件45运动,阀杆组件45由第二位置移动至第一位置,第一通道41和第三通道43连通,驱动气体经由第一通道41进入第三通道43,压力传感器60检测到第三通道43内的驱动气体压力高至某一预设值时,控制开关阀70打开,驱动气体经由第一通道41和第三通道43进入储药池30,麻醉蒸发器100恢复正常工作状态。
在第三实施例中,请参阅图5和图6,联动机构50伸入储药池30上的加药筒31内,操作人员打开盖体20后,将加药容器200推入加药筒31的过程中,联动机构50的末端与加药容器200相配合,并随加药容器200发生运 动,从而带动机械卸压组件40的部分结构运动,进而阻止驱动气体继续进入储药池30,同时储药池30内的高压驱动气体排出,实现卸压。其他结构均与第一实施例相同,不再赘述。
具体的,联动机构50远离阀杆组件45的一端穿过加药筒31上开设的滑槽311,进入加药筒31内部,加药容器200插入加药筒31时,联动机构50的末端抵持于加药容器200上的配合部210,加药容器200沿加药筒31推入的过程中,联动机构50推动阀杆组件45运动。
联动机构50包括转动连接的传动体54和连接体55,连接体55的另一端转动连接于阀杆组件45,传动体54的中部设有一固定支点56,传动体54的末端与加药容器200的配合部210抵接,加药容器200沿加药筒31推入的过程中,推动传动体54绕固定支点56转动,并带动连接体55运动,从而推动阀杆组件45移动。
