为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面
描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他实施例的附图。

图4为图1中圆圈A部分结构的局部放大图。
为了便于理解本发明,下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是,本发明可以以许多不同的形式来实现,并不限于本文所描述的实施方式。相反地,提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是,当元件被称为“固定于”另一个元件,它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件,它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的,并不表示是唯一的实施方式。
除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的,不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
本发明一实施例提供的麻醉机,包括组件连接座,用于装配组件。可以理解的,在一些具体应用中,如图1和图2所示,组件可以是麻醉蒸发器20,相应的,该组件连接座可以是麻醉蒸发器连接座10。当然,组件也可以是麻醉机插件模块等。下面将以麻醉蒸发器连接座10为例对组件连接座的结构作进一步说明。
该麻醉蒸发器连接座10包括壳体11、接口12以及接口保护装置13。
如图2和图3所示,接口12设于壳体11内,且壳体11上开设有与接口12相对的插孔111。接口保护装置13可以根据麻醉蒸发器20与麻醉蒸发器连接座10的装配状态,选择性的使插孔111露出接口12或让接口12被接口保护装置13遮挡住,需要说明的是,接口12被遮挡住时,接口12就不会暴露在外而沾染灰尘或病菌。
需要说明的是,上述实施方式中,对于接口12和插孔111的数量不受限制,可以是一个,也可以是多个。
如图1所示,壳体11上具有多个插孔111,分别为第一插孔111a、第二插孔111b、第三插孔111c和第四插孔111d。可以理解的,多个插孔111的形状可以相同,也可以根据实际需要配置成不同形状的插孔111。相应的,如图2和图3所示,插孔111是开设壳体11与接口12相对的位置,即,接口12的数量及类型也可以根据实际需要配置,在图2和图3中,分别有第一接口12a、第二接口12b、第三接口12c和第四接口12d,这些接口12可以是通气用的气路接口,也可以是通电用的电路接口。可以理解的,组件连接座上的气路接口是可以与组件实现对接的,例如雾化接口、气体采样接口或麻醉蒸发器接口,在此不作限定。
该接口保护装置13包括阻挡件131、驱动机构和触发机构135。阻挡件131可以在驱动机构的作用下,在第一位置和第二位置间移动;触发机构135用于检测麻醉蒸发器20的装配和卸载行为。需要说明的是,阻挡件可以设置在壳体11上,也可以设置在壳体11与所述接口12之间。在本实施方式中,当阻挡件131移动到第一位置时,插孔111露出接口12;当阻挡件131移动到第二位置时,阻挡件131遮挡接口12。
上述实施方式中,当所述触发机构检测到麻醉蒸发器20装配行为时,触发所述驱动机构将所述阻挡件移动到所述第一位置,当所述触发机构检测到麻醉蒸发器20卸载行为时,触发所述驱动机构将所述阻挡件移动到所述第二位置。也就是说,在触发机构检测到麻醉蒸发器20装配行为时,会触发驱动
机构将阻挡件移动到第一位置,插孔111露出接口12,麻醉蒸发器20的接头可以穿过插孔111与接口12相连,接通电路和/或气路;相应的,在触发机构检测到麻醉蒸发器20卸载行为时,会触发驱动机构当阻挡件131移动到第二位置时,阻挡件131遮挡住接口12,从而避免了接口12在不与麻醉蒸发器20连接时露出外界,从而对接口12进行良好的保护,防止接口12上沾染灰尘或病菌而危害患者。
阻挡件131还可以通过遮挡插孔111的方式,将接口12与外界隔绝。例如将阻挡件131设置在壳体11的外侧。因此,当将麻醉蒸发器20从麻醉蒸发器连接座10上移除时,驱动机构驱动阻挡件131移动到第二位置,阻挡件131将插孔111密封住,从而防止灰尘或病菌从插孔111进入壳体11内而污染接口12,感染到病患。
需要说明的是,驱动阻挡件131在第一位置和第二位置之间移动可以采用机械结构作为驱动力,即,麻醉蒸发器20装配到麻醉蒸发器连接座10时,通过触发机构135对驱动机构施加的作用力。当然,也可以采用电动结构作为驱动力,即不需要麻醉蒸发器20的装配提供动力,而是根据麻醉蒸发器20与麻醉蒸发器连接座10的装配和卸载行为,触发相应的电动结构为驱动机构移动阻挡件131提供动力。
驱动机构包括驱动组件和复位组件,当触发机构检测到麻醉蒸发器20装配行为,驱动组件带动阻挡件移动到第一位置;当触发机构检测到麻醉蒸发器20卸载行为时,复位组件驱动阻挡件移动到第二位置。在麻醉蒸发器连接座10上装配麻醉蒸发器20的过程中,麻醉蒸发器20可以经触发机构在驱动组件上施加作用力,从而借助驱动组件将阻挡件131移动到第一位置。而在移除麻醉蒸发器20时,由于麻醉蒸发器20施加在驱动组件上的作用力消失,此时,复位组件就可以将阻挡件131从第一位置恢复到第二位置。可见,在阻挡件131移动到第一位置的过程中,复位组件在存储能量,以在麻醉蒸发器20移除时,释放所存储的能量而使阻挡件131恢复到第二位置。
驱动组件包括连接件132和传动件133。连接件132的一端132a连接于
阻挡件131上,另一端132b与传动件133相铰接。所述传动件133通过连接件132带动所述阻挡件131在第一位置和第二位置之间移动。需要说明的是,传动件133可以相对于11运动,比如将传动件133可转动地设置在壳体11内,且连接件132与传动件133的铰接点偏离传动件133相对壳体11转动的转动轴线;以在传动件133相对于壳体11转动时,传动件133可以经过连接件132驱动阻挡件131在第一位置和第二位置之间移动。此外,传动件133可以由电机或电磁铁提供驱动力。
其它实施方式中,传动件133可以采用摆杆结构,也可以采用凸轮结构,在连接件132与传动件133的铰接点偏离传动件133的转动轴线时,摆杆结构和凸轮结构均能实现连接件132的往复运动,进而带动阻挡件131在第一位置和第二位置之间移动。可以理解的,驱动组件还可以是连杆机构、同步带、齿轮或链条。
需要说明的是,触发机构可以采用电子触发的方式,例如行程开关、光电传感器或霍尔传感器。其中,行程开关是通过按压实现触发检测,光电传感器是通过遮挡实现检测,霍尔传感器是通过磁场变化来实现检测。
具体的,触发机构采用行程开关时,当麻醉蒸发器20装配到麻醉蒸发器连接座10的过程中,按压行程开关直至行程开关的状态发生改变,进而触发驱动机构将阻挡件131移动到第一位置;相应的,在移除麻醉蒸发器20的过程中,麻醉蒸发器20同时也会失去对行程开关的按压作用,进而在行程开关的状态发生切换时,触发驱动机构动作,将阻挡件131移动到第二位置。
可以理解的,触发机构采用光电传感器时,在装配和卸载麻醉蒸发器20的过程中,光电传感器的遮挡状态会发生改变,进而触发驱动机构将阻挡件131在第一位置和第二位置间移动。
由于霍尔传感器是通过磁场变化来实现检测,因此,在触发机构采用霍尔传感器来实现检测麻醉蒸发器20装配和卸载行为时,装配和卸载麻醉蒸发器20的过程中,会导致磁场的变化,进而改变霍尔传感器的状态。因此,通过霍尔传感器状态的改变,可以触发驱动机构动作,相应的驱动阻挡件131
移动到第一位置和第二位置。
具体的,如图2和图3所示,触发机构包括设置在传动件133上的按压件135,且按压件135至少部分伸出于壳体11外,以在麻醉蒸发器20装配到麻醉蒸发器连接座10上时,麻醉蒸发器20经按压件135驱动传动件133相对于壳体11转动,从而使传动件133带动连接件132运动,使与连接件132相连的阻挡件131在第一位置和第二位置之间移动。
具体的,在装配麻醉蒸发器20时,麻醉蒸发器20自身的重力作用,按压在按压件135上,使得按压件135向下(图3中箭头D方向)运动,进而使传动件133相对于壳体11转动;此时,与传动件133相连的连接件132便将阻挡件131从第二位置移动到第一位置。
需要说明的是,上述实施方式中,壳体11上设有滑套112,按压件135可活动的插接在滑套112内,从而在将麻醉蒸发器20放置在按压件135上时,按压件135沿滑套112上下运动,以稳定的抵压传动件133。此外,传动件133可以通过连接片114转动连接在壳体11上。壳体11内设有抵持部113,传动件133在复位组件的作用下,保持与抵持部113相抵,也就是说,在抵持部133对传动件133的限位作用下,传动件133在与支持部113相抵后,不会继续相对壳体11转动,由于传动件133与连接件132相连,因而连接件132可以将阻挡件131保持在第一位置。
需要说明的是,按压件135可以设置在麻醉蒸发器连接座10的底部,按压件135伸出壳体11的部分设有楔形坡面135a,以在麻醉蒸发器20推向接口12(沿图3中箭头P方向)时,麻醉蒸发器20的底部抵压并沿楔形坡面135a滑动。楔形坡面135a使得麻醉蒸发器20可以通过平移的方式逐渐抵压按压件135。可以理解的,可以将按压件135设置在距离接口12合理的位置处,这样,在麻醉蒸发器20在按压件135的楔形坡面135a上滑动至邻近接口12时,阻挡件131完全离开而将接口12暴露出来,以与麻醉蒸发器20的连接。
按压件135上远离楔形坡面135a的一端设有凸头135b,凸头135b抵接
于传动件133上,从而使按压件135与传动件133之间点接触,以在按压件135按压传动件133相对壳体11转动时,凸头135b与传动件133的接触面小,不会限制传动件133的转动效果。此外,按压件135作用在传动件133的作用点都集中在凸头135b处,因此,在传动件133相对壳体11转动的过程中,按压件135施加在传动件133上的作用点基本相同,使得传动件133相对壳体11转动更稳定。凸头135b与传动件133呈球面接触,提高凸头135b的抗压强度,避免长期与传动件133之间的转动而磨损。
在另一些实施方式中,按压件135还可以设置在麻醉蒸发器连接座10的竖直侧壁上,以在麻醉蒸发器10推向接口12时,抵压该按压件135,而使阻挡件131移动至第二状态,在此不再一一赘述。
结合图1和图4,麻醉蒸发器连接座10设置有导向结构115,使得麻醉蒸发器20可以沿着导向结构115推向接口12,麻醉蒸发器20的接头比较容易对准接口12,以实现快速麻醉蒸发器20的快速装配。在导向结构115上还设有操作指示区1152,具体的,该操作指示区1152示出了装配麻醉蒸发器20时沿导向结构115的推进方向,此外,在导向结构115靠近接口12的一端设有侧棱1151,相应的,麻醉蒸发器20的底部设有与导向结构115上的侧棱1151相匹配的导向槽,使得麻醉蒸发器20在沿导向结构115推向接口12时,导向槽会沿侧棱1151滑动,也就是说,侧棱1151与导向槽的配合限制了麻醉蒸发器20在竖直方向上的运动,因而,在按压件135的楔形斜面具有向上抵压麻醉蒸发器20的力时,该侧棱1151与导向槽的配合也会相应在麻醉蒸发器20上施加一个朝下(图3中箭头D方向)的反作用力。因而,即使在麻醉蒸发器20的自身重力不足以克服复位组件作用在传动件133上的力时,也不需要医护人员用力下压按压件135,只需要朝接口12方向(图3中箭头P方向),就可以使麻醉蒸发器20沿按压件135的楔形坡面135a滑动并驱动传动件133相对壳体11转动,进而实现将阻挡件131移动至第一位置。
复位组件可以采用弹性元件,如图2和图3所示,弹性元件为拉簧134,拉簧134的两端分别与壳体11和传动件133相连;当触发机构检测到麻醉蒸
发器20装配麻醉蒸发器行为时,传动件133相对于壳体11运动而拉伸拉簧134,并在麻醉蒸发器触发机构检测到麻醉蒸发器卸载行为时,拉簧134收缩以带动传动件133相对于壳体11活动而将阻挡件131移动到第二位置。
需要说明的是,麻醉蒸发器不仅可以通过复位组件来驱动阻挡件131从第一位置移动到第二位置,完成阻挡件131的复位动作,也可以利用驱动组件的反向运动来实现。也就是说,驱动机构不仅可以在装配麻醉蒸发器20的时候,驱使阻挡件131移动到第一位置,而使插孔111露出接口12,以供麻醉蒸发器20连接;而且,在将麻醉蒸发器20麻醉蒸发器卸载的过程中,驱动机构还可以向相反的方向运动,从而使阻挡件131从第一位置恢复到第二位置,即,将接口12遮挡住,即接口12与外界隔离,从而防止外界的灰尘或病菌沾染到接口12上而危害患者。
阻挡件131可以通过上下运动或左右运动等平移的方式在第一位置和第二位置之间移动;还可以通过阻挡件131与壳体11之间发生相对转动而实现遮挡接口12。例如:将阻挡件131转动连接在壳体11上,在阻挡件131处于第一位置时,阻挡件131上具有与插孔111相对的导通孔131,也就是说,在阻挡件131处于第一位置时,阻挡件131未遮挡插孔111,使得此时接口12可以通过插孔111露出,以与麻醉蒸发器20上相应的接头相连。在阻挡件131相对壳体11转动而处于第二位置时,阻挡件131上的导通孔131就会错开插孔111,从而遮挡住插孔111,使得接口12在未与麻醉蒸发器20连接时,接口12和插孔111之间阻隔着阻挡件131,从而防止外界的灰尘或病菌沾染到接口12上。当然,该实施方式中,阻挡件131也可以通过平移的方式相对壳体11移动,从而选择插孔111与导通孔131相对或错开。
需要说明的是,在一些具体应用中,导通孔131的数量和位置可以根据插孔111的数量和位置确定,以图2和图3示出的结构为例,壳体11上开设有第一插孔111a、第二插孔111b、第三插孔111c和第四插孔111d,将阻挡件131移动到第一位置时,只要阻挡件131的顶端低于第一插孔111a,相应只需在阻挡件131上开设分别与第二插孔111b、第三插孔111c和第四插孔
111d相对的第一导通孔131a、第二导通孔131b和第三导通孔131c即可,当将阻挡件131向上移动至第二位置时,由于上述的导通孔131与接口12相互错开,使得阻挡件131遮挡在接口12处,实现对接口12的保护。
其它实施方式中,在阻挡件131上开设槽缝等可以选择性连通插孔111和接口12的结构。此外,阻挡件131还可以采用多个间隔设置的板材构成,以在第一位置和第二位置移动时,多个间隔设置的板材开启或遮挡插孔111;具体的,在第一位置时,板材之间的间隔可以供接口12从插孔111露出,以便麻醉蒸发器20的接头可以穿过插孔111与接口12相连;相应的,在第二位置时,插孔111被板材遮挡住,从而避免在麻醉蒸发器20未装配到麻醉蒸发器连接座10时接口12从插孔111暴露在外,以防止外界的灰尘或病菌污染接口12。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
