技术领域
本发明涉及液体药品技术领域,特别涉及一种取液装置、具有该取液装置的药瓶组件及取液方法。
背景技术
目前,液体药品的取用通常有以下两种方式:
第一种方式为直接倾倒方式,即将药瓶的瓶盖打开,操作者手持药瓶直接将药瓶中的药液自瓶口倾倒至容器内部。这种方式取液基本靠操作者的经验,无法做到定量取液。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
针对背景技术中存在的上述技术问题,本文进行了深入研究,并提出了一种解决上述技术问题的技术方案,具体描述如下。
为了使本领域的技术人员更好地理解本发明的技术方案,下面结合附图和具体实施例对本发明作进一步的详细说明。本文以取液装置在医用领域的应用为例介绍,当然,本领域内技术人员应当理解,本文所述的取液装置不限于应用于医药领域,应用于其他需要定量取液的环境也在本文的保护范围之内。
请参考图1至图10,本发明提供了一种取液装置,该取液装置主要盖合于药瓶体8’的开口,即起到瓶盖的作用,又可以实现取液的作用。本文中的取液装置包括盖体1’、转接部件30’和取液管4’。
其中取液管4’包括管体404’、出口403’和进口401’,管体404’形成有 内腔,进口401’和出口403’设置在管体404’上,并且通过内腔连通。管体的具体形状不做限定,本文优选为长条形结构。本文中管体的出口403’尺寸优选室内压力下,液体不会流出,只有在受到高于室内压力作用下,取液管4’内的液体才会流出。
本发明中的盖体1’包括安装部,用于与要瓶体的开口密封配合。安装部的具体结构可以根据其所应用的药瓶体8’开口结构配合加工,安装部可以可拆卸连接于药瓶体8’上,例如安装部可以为螺旋结构,其通过螺纹密封连接药瓶体8’的螺纹开口。即药瓶体8’设置有内螺纹部,用于与药瓶体8’的开口端的外螺纹部配合安装。当然,安装部可以为光轴结构,其过盈安装于药瓶体8’的开口内部。进一步地,盖体1’还可以设置有防开齿101’,用于与药瓶体开口端部的防开结构配合。防开齿101’的具体结构可以参考现有技术。
当然,安装部的结构不局限于本文所描述的以上两种结构,可以根据具体应用环境,合理设置。
盖体1’上设置有一端用于连通药瓶体8’的溶液腔的取液通道104’,取液管4’通过转接部件30’安装于盖体1’外部。
当转接部件30’处于第一位置,取液管4’的进口401’与取液通道104’的另一端连通;当转接部件30’处于第二位置,取液通道104’与取液管4’进口401’断开。取液装置还包括回气通道,用于取液时或取液后对药瓶体8’溶液腔回气。
本发明所提供的盖体1’、转接部件30’和取液管4’加工完毕后,可以先预组装形成取液装置,当药瓶体8’内部盛装完药液后,在生产线将组装形成一体的取液装置与药瓶体8’组装形成药瓶组件。
当取液时,将转接部件30’置于第一位置,药瓶体8’内的药液可以沿取液通道104’、取液管进口401’形成的通路进入取液管4’的内腔,当取液到达预定量时,可以将转接部件30’处于第二位置,此时取液通道104’与取液管进口401’断开,取液管4’内的液体可以自出口403’再流至外部以供使用。取液管4’内液体流至外部可以通过挤压动力流至外部。
从以上描述可以看出,本发明所提供的取液装置在取液时,无需打开盖体1’,并且通过设置取液管4’的量程可以实现定量取液,这样大大降低 外部环境与药瓶体8’内液体接触的可能性,降低药瓶体8’内部药液被污染情形的发生,有利于保障药品的效力。并且本发明所提供的取液装置设置有回气通道,在取液过程中或者取液结束后可以对药瓶体8’的溶液腔进行回气。
当然回气通道只是从功能上进行的限定,其可以与取液通道104’是同一通道,二者也可以为不同的通道,只要能够实现回气即可。
请结合图1,在一种具体实施例中,取液管4’的进口401’和出口403’分别布置于管体相对两端部,管体安装于转接部件30’。转接部件30’一端转动密封安装于盖体1’,也就是说,转接部件30’可以相对盖体1’转动并且二者密封接触。
转接部件30’至少设置有第一通道和第二通道,当转接部件30’相对所述盖体1’转动至第一位置时,取液管4’通过第一通道连通取液通道104’,第二通道与取液通道104’不连通;当转接部件30’转动至第二位置时,第一通道与取液通道104’断开,第二通道与取液通道104’连通以形成回气通道。
该实施例中的取液装置与药瓶体8’组装形成药瓶组件后,为了减小包装,可以优选常态下取液管4’与药瓶体8’处于同侧,取液时,将转接部件30’转动至第一位置,可以挤压药瓶体8’或者将药瓶体8’倒置以使药瓶体8’内的药液沿取液通道104’、第一通道进入取液管4’的内腔中,待取液结束后,将转接部件30’转动至第二位置关闭取液通道104’与取液管4’进口401’之间的连通通道,同时连通第二通道、取液通道104’以使二者形成回气通道,即此时外部气体可以沿第二通道、取液通道104’进入药瓶体8’内部,以使药瓶体8’内部气压与外部环境平衡。
该实施例中,转接部件30’通过转动实现第一位置和第二位置的转换,从而实现取液和回气的转换,简单方便。
上述转接部件30’可以直接连接在盖体1’上,当然也可以间接转动连接盖体1’,即为了降低加工工艺,盖体1’上还可以安装有连接块2’,转接部件30’转动安装于连接块2’上。
具体地,连接块2’设置于盖体1’,图1中示出了连接块2’横向设置于盖体1’,并且连接块2’包括漏置于盖体1’外部的安装轴段,转接部件30’转 动安装于安装轴段。即转接部件30’具有与安装轴段配合转动的安装孔306’,第一通道为开设于安装孔周壁的第一通孔303’。安装孔306’的周壁还开设有回气通孔301’。
连接块2’可以部分位于盖体1’内部,部分位于盖体1’外部,当然,连接块2’也可以完全位于盖体1’外部。本文以后者为例继续描述技术方案,即连接块2’完全位于盖体1’外部。
安装轴段的外表面沿周向开设有第一孔203’和第二孔202’,连接块2’内部设有连通通道,连通通道的一端连通盖体1’的取液通道104’,另一端与第一孔203’、第二孔202’均连通。
连接块2’和转接部件30’二者可以通过相互配合的环形的密封凹槽和环形凸台的形式配合密封转动,如图3所示转动部件3的安装孔内部设置有密封凹槽302’,连接块相应的配合位置设置有环形凸台,图中未示出环形凸台,但是并不妨碍本领域内技术人员对上述技术方案的理解。
当转接部件30’转动至第一位置时,第一孔203’与第一通孔303’连通、第二孔202’与回气通孔301’断开;此时,药瓶体8’的溶液腔通过盖体1’的取液通道104’、连通通道、第一孔203’、第一通孔303’连通取液管4’的进口401’,以实现取液。
当转接部件30’转动至第二位置时,第一孔203’与第一通孔303’断开,第二孔202’与回气通孔301’连通,此时,药瓶体8’的溶液腔通过盖体1’的取液通道104’、连通通道、第二孔202’、回气通孔301’连通外界环境,以实现药瓶体8’的溶液腔回气。
当然,安装轴段上也可以进开设一个孔,取液、回气和喷液均通过一个孔实现。例如,安装轴段的外表面沿周向仅开设有第一孔203’,连接块2’内部设有连通通道,连通通道的一端连通盖体1’的取液通道104’,另一端与第一孔203’连通;当转接部件转动至第一位置时,第一孔203’与第一通孔303’连通、第一孔203’与回气通孔301’断开;当转接部件转动至第二位置时,第一孔203’与第一通孔303’断开,第一孔203’与回气通孔301’连通。
回气之后,压缩药瓶体可以直接将取液管内的药液喷送至外部。
在设置第一孔203’和第二孔202’的基础上,本发明还可以进一步如 下设置。
进一步的,安装轴段上还可以设置有第三孔204’,并且第一孔203’、第二孔202’和第三孔204’沿周向依次间隔布置;连通通道的另一端与第三孔204’也连通;当转接部件30’转动至第三位置时,第三孔204’与第一通孔303’连通,第二孔202’与回气通孔301’断开,并且此时药瓶体8’开口向上,取液管4’的出口403’斜向下。
也就是说,当转接部件30’处于第一位置和第三位置时,分别可以通过第一孔203’、第三孔204’均连通取液管4’的进口401’。第一孔203’、第二孔202’、第三孔204’沿安装轴段的周向依次布置。本实施例中设置第三孔204’,主要考虑利用可压缩药瓶体8’作为取液管4’中药液的喷出动力,即当取液通道104’通过第三孔204’与取液管4’连通后,可以压缩药瓶体8’,在药瓶体8’气体冲击力的作用下,取液管4’内的药液由出口403’喷出。并且该实施方式中第一孔203’、第二孔202’和第三孔204’沿周向依次布置,这样取液管4’可以沿同一个方向依次转动至相应位置,分别实现取液、回气和喷液,使用方便。
该实施方式在保证取液量精确可控的前提下,可以有效将取液管4’的内腔与药液瓶的内腔隔离,有利于提高药液瓶内部药液的有效性。
如图6所示,第二孔202’的数量可以为两个,二者关于第一孔203’所处的轴向面对称布置;或者/和,第三孔204’的数量为两个,二者关于第一孔203’所处的轴向面对称布置。
这样,取液管取液后,顺时针转动可以实现回气、喷液操作,同样逆时针转动也可以实现回气、喷液操作。进一步方便操作便利性。
在一种具体实施例中,连接块2’包括大径轴段22’和小径轴段21’,小径轴段21’为安装轴段,大径轴段22’和小径轴段21’的台阶面23上设置有沿周向布置的喷液定位块2072’和回气定位块2071’,转接部件30’的安装孔端面设置有限位块304’;当转接部件相对连接块转动时,限位块304’与回气定位块2071’配合限定回气位置,限位块304’与喷液定位块2072’配合限制喷液位置;并且限位块先经过且能够转过回气定位块2071’,且再转动至喷液定位块2072’。
进一步地,还包括单向阀组件5’,用于控制取液通道104’与取液管4’ 的内腔之间的连通管道单向导通。也就是说,使药瓶体内部的药液自取液通道104’单向流动至取液管4’的内腔。
单向阀组件5’的安装位置可以有多种方式,例如盖体内部、取液管4’内部通道、转接部件30’内部通道等。
单向阀组件5’可以为弹性组件,常态下,单向阀组件5’以预设压力抵靠阀口以关闭阀口。
在一种具体实施方式中,单向阀组件5’包括阀芯51’以及弹簧52’,第一通道形成有阀口,阀芯51’具有与阀口配合密封的表面,弹簧52’压设于第一通道的内壁和阀芯51’之间。该结构简单,占空间小。
上述各实施例中,转接部件30’可以包括配合轴段,配合轴段插入取液管4’的进口401’并且与取液管4’的相应内周壁周向密封,阀口形成于所述第一通道位于配合轴段内部的孔道,弹簧52’及阀芯51’位于所述配合轴段内部;还包括安装于第一通道内腔壁的安装板53’,所述弹簧52’压设于安装板53’与阀芯51’之间。安装板53’的结构有多种方式,例如环形、带孔板状等等,只要能够实现弹簧52’的有效支撑且不妨碍液体得了流通即可。第一通道中可以加工有安装板孔305’,安装板53’设于安装板孔305’内部。
配合轴段的孔道在一定程度上起到弹簧52’形变导向的作用,且该安装方式结构密封性强。
上述各实施方式中,盖体1’包括横向向外延伸的安装轴体103’,连接块2’具有与安装轴体103’配合套装的安装孔205’,并且安装轴体103’和安装孔部二者其中一者设置有横向延伸的防转凸台102’,另一者设置有与防转凸台102’配合的键槽。请参考图5和图7,本文中给出了连接块2’上设置键槽201’,盖体上设置防转凸台102’的具体实施方式。
当然,盖体1’与连接块2’可以为整体结构,也可以如上述所述二者为两个独立的部件。
请参考图9和图10,在设置第三孔204’的取液装置的实施例基础上,本文还提供了一种取液方法,具体步骤包括:
S1、将上述取液装置与已罐装药液的药瓶体8’组装形成药瓶组件,常态下,取液管4’与药瓶体8’同侧设置且所述药瓶体8’开口朝上,所述取液 管4’的出口403’朝下;
S2、取液时将上述药瓶组件倒置,转动转接部件30’至第一位置,此时取液管4’的出口403’大致朝上,连通压缩药瓶体8’使药液流动至取液管4’的管体内部;
S3、待取液达到预设需求量时,转接部件30’向斜上方转动至第二位置,连通回气通孔301’与取液通道104’,以使药瓶体8’回气;
S4、药瓶体8’回气结束后,继续沿同一方向转动转接部件30’至第三位置,此时取液管4’的出口403’斜向下,压缩药瓶体8’以使取液管4’内部液体自出口403’喷至外部。
在上述取液装置的基础上,为了精确控制流入取液管4’内的液体量,本文还进行了以下设置。
上述各实施例中还可以包括单向阀组件5’,取液管4’的进口401’或第一通道形成有阀口,常态下,单向阀组件5’以预设压力抵靠阀口以关闭阀口。
该实施例中,药瓶体8’通常为容积可压缩式式结构,这样在取液时,在压缩药瓶体8’力作用下,药瓶体8’内的气体或液体推动单向阀组件5’动作,以打开阀口,药液流入取液管4’的内腔,当到达取液量时,撤销作用与药瓶体8’上的作用力,单向阀组件5’回复至初始位置重新抵靠阀口以关闭阀口。
上述各实施例中,取液装置还可以包括密封帽6’,密封帽6’可拆卸地安装于取液管4’的出口403’端部。
进一步地,密封帽6’与取液管4’螺纹密封连接;如图8所示,管体404’的外端部外表面设置有密封螺纹结构402’,以配合密封帽6’安装。或者,密封帽6’的内壁具有插入取液管4’的出口内部的密封柱。
此外,本发明还提供了一种药瓶组件,包括具有容液腔的药瓶体8’,还包括上述任一项所述的取液装置,取液装置的盖体的安装部与所述药瓶体8’的开口密封配合,取液管位于药瓶体8’的外部。
并且,药瓶体8’可以为可压缩式容积可变结构,以便当取液结束压缩所述药瓶体8’时,取液管内部液体可自其出口403’喷出。
当然药瓶体8’的结构不局限于本文上述描述,还可以为其他结构。
再者,在上述取液装置、药瓶组件的基础上,本发明还提供了一种取液方法,具体为:
S1、将上述的药瓶组件罐装药液,常态下,取液管与药瓶体同侧设置且所述药瓶体开口朝上,所述取液管的出口朝下;
S2、取液时,将上述药瓶组件倒置,转动转接部件至第一位置,此时取液管的出口大致朝上,压缩药瓶体使药液流动至取液管的管体内部;
S3、待流至取液管内部的液体达到预设需求量时,转接部件向斜上方转动至第二位置,断开取液管与取液通道、连通回气通孔与取液通道,以使药瓶体回气;
S4、药瓶体回气结束后,继续沿同一方向转动转接部件至第三位置,此时所述药瓶体开口向上,且取液管的出口斜向下,压缩药瓶体以使取液管内部液体自出口喷至外部。
本文中上述所提供的药瓶组件包括上述取液装置、取液方法是在上述取液装置的基础上实施例的,故药瓶组件和取液装置也具有取液装置的上述技术效果。
在同一发明思路的基础上,本发明还提供了另外一种取液装置的具体实施方式。
请参考图11至图14,本发明还提供了一种取液装置,该取液装置主要盖合于药瓶体8的开口,即起到瓶盖的作用,又可以实现取液的作用。本文中的取液装置包括盖体1和取液管2。
其中取液管2包括管体、出口2a和进口2b,管体形成有内腔,进口2b和出口2a设置在管体上,并且通过内腔连通。管体的具体形状不做限定,本文优选为长条形结构。本文中管体的出口2a尺寸优选室内压力下,液体不会流出,只有在受到高于室内压力作用下,取液管2内的液体才会流出。
本发明中的盖体1包括安装部,用于与要瓶体的开口密封配合。安装部的具体结构可以根据其所应用的药瓶体8开口结构配合加工,安装部可以可拆卸连接于药瓶体8上,例如安装部可以为螺旋结构,其通过螺纹密封连接药瓶体8的螺纹开口。当然,安装部可以为光轴结构,其过盈安装于药瓶体8的开口内部。
当然,安装部的结构不局限于本文所描述的以上两种结构,可以根据具体应用环境,合理设置。
盖体1上设置有一端用于连通药瓶体8的溶液腔的取液通道1a,取液管2转动安装于盖体1外部。
当取液时,取液管2的进口2b与取液通道1a的另一端连通;当非取液时,取液通道1a与取液管2进口2b断开。取液装置还包括回气通道,用于对药瓶体8溶液腔回气。
本发明所提供的盖体1和取液管2加工完毕后,可以先预组装形成取液装置,当药瓶体8内部盛装完药液后,在生产线将组装形成一体的取液装置与药瓶体8组装形成药瓶组件。
当取液时,药瓶体8内的药液可以沿取液通道1a、取液管2进口2b形成的通路进入取液管2的内腔,当取液到达预定量时,可以将取液装置置于非取液位置,此时取液通道1a与取液管2进口2b断开,取液管2内的液体可以自出口2a再流至外部以供使用。取液管2内液体流至外部可以通过挤压动力流至外部。
当然回气通道只是从功能上进行的限定,其可以与取液通道1a是同一通道,二者也可以为不同的通道,只要能够实现回气即可。
在一种具体实施方式中,取液管2可以为一端封闭,另一端设置有出口2a,进口2b设置于取液管2的周向侧壁,取液管2大致为长条形管,该实施例中进口2b设置于取液管的周向侧壁,而非端部。
取液管2的内腔包括相互连通的第一腔室21和第二腔室22,第一腔室21和第二腔室22分居于进口2b的上下两侧,此处上下是以图1中各零部件之间的相对位置关系为参照而定义,仅是为了描述技术方案的简单,本领域内技术人员应当理解不对本文所记载技术方案具有限定作用。
本实施例中取液管的出口2a设置于第一腔室21;取液管2转动安装于盖体且转动轴为横向,需要说明的是,横向是指沿盖体1径向,即图1中水平方向。
该实施方式中的取液管2在使用时,因进口2b设置于周向侧壁,第二腔室22可以作为取液时的存储腔室,而进口2b之上的第一腔室21可以作为回气通道,即当取液结束后,因药液存储于第二腔室22,旋转药瓶体开 口朝上时,这样出口2a、第一腔室21、进口、取液通道可以形成回气通道,对药瓶体8进行回气,这样无需再另外设置回气通道,结构可简化。
优选实施方式中,取液时时,药瓶体开口朝下,取液管的出口朝上进行取液;取液完毕,旋转药瓶体8使其开口朝上进行回气。在完成取液时,避免液体洒落。当然,取液管2的出口朝上并非绝对意义上的竖直向上,可以斜向上,只要满足液体不洒落即可。
从以上描述可以看出,本发明所提供的取液装置在取液时,无需打开盖体1,并且通过设置取液管2的量程可以实现定量取液,这样大大降低外部环境与药瓶体8内液体接触的可能性,降低药瓶体8内部药液被污染情形的发生,有利于保障药品的效力。并且本发明所提供的取液装置设置有回气通道,在取液结束后可以对药瓶体8的溶液腔进行回气。
请再次参考图11至图14,在第一种具体实施方式中,取液装置还可以设置有转接部件3’,转接部件3’横向安装于盖体,并且转接部件3’包括漏置于盖体外部的安装轴段,取液管2的外部具有径向延伸的安装段,安装段设置有径向通孔,径向通为取液管的进口,安装轴段密封转动安装于径向通孔内部,转接部件设置有能够连通进口2b和取液通道1a的中间通道31’。当转接部件位于第一位置时,取液通道1a通过中间通道31’连通进口2b;当转接部件处于第二位置时,中间通道31’关闭。
本实施方式中通过转接部件3’实现盖体1与取液管2的连通或断开,结构简单易于实施。
盖体1设置有横向延伸的安装孔,转接部件3’包括密封轴段,密封轴段配合安装于安装孔并且二者沿横向滑动密封,当转接部件3’沿横向密封滑动至第一位置时,中间通道31’与取液通道连通;当转接部件3’密封滑动至第二位置时,密封轴段封堵取液通道的出口2a。
通过上述设置,常态下,密封轴段34’封堵取液通道,实现药瓶体8内药液的密封保存,取液时将密封轴段34’滑动之打开取液通道位置。
具体地,转接部件3’的两端部分别设置有至少一条第一环形凸台32’和至少一条第二环形凸台33’所述第一环形凸台32’与盖体1上的凹槽23滑动密封;第二环形凸台33’与取液管开口设置的凹槽23配合密封。
请参考图14和图15,在上述具有密封轴段的取液装置实施例的基础 上,以下提供了一种取液方法,具体包括:
S10、将取液装置与已罐装药液的药瓶体8组装形成药瓶组件,常态下,所述药瓶体8开口朝上,所述取液管的出口2a朝上,并且所述密封轴段密封所述取液通道;
S20、取液时将上述药瓶体8相对转动以使其倒置,保持取液管的出口2a朝上,使密封轴段滑动至第二位置以打开取液通道,压缩药瓶体8使药液流动至取液管的第二腔室22;
S30、待取液达到预设需求量时,药瓶体8转动至出口2a朝上状态并通过取液管的出口2a、第一腔室21、中间通道31’和取液通道1a形成的回气通道回气,回气结束后,将取液管转动至出口2a斜向下状态,使第二腔室22内的药液流动至第一腔室21,压缩药瓶体8以使第一腔室21内的药液喷至外部。
请参考图16至图20,在另一种具体实施例中,盖体1外周壁和取液管2的外壁其中一者设置有径向延伸的安装轴段,另一者周壁设置有开口朝外的安装槽,安装轴段周向密封安装于安装槽,安装槽的底壁和安装轴段均设置有连通通道,当取液管2相对盖体1转动至第一位置时,盖体1的取液通道通过安装槽底壁的连通通道、安装轴段的连通通道连通取液管的内腔;当取液管2相对盖体1转动至第二位置时,安装槽底壁的连通通道与安装轴段的连通通道断开。
也就是说,该实施例中通过取液管的转动实现其内腔与取液通道的连通和断开。
具体的,上述实施例中的回气通道可以如下设置。
上述实施例中,安装轴段和安装槽底壁其中一者设置有并行的两条连通通道:取液孔103和回气/喷液孔102;当取液管处于第一位置时,取液孔103连通与另一者的连通通道连通以实现取液;当所述液管处于第二位置时,回气/喷液孔102与另一者的连通通道连通以实现回气和喷液,该状态下,取液管2的进口斜向下。
即安装轴段上可以设置两条并行连通通道,取液管2处于不同状态时,两条连通通道可选择地与安装槽底壁上的连通通道连通,以实现取液、回气和喷液功能。当然,两条并行连通通道也可以设置于安装槽底壁上,可 选择地与安装轴段上的连通通道连通,以实现取液、回气和喷液功能。
该实施方式中,回气位置与喷液位置相同,简化结构。
本文以盖体设置安装轴段101、取液管2设置有安装槽为例进一步介绍技术方案和技术效果。具体的,取液管2的外周壁具有径向向外延伸的安装段203,安装段203设置有安装槽205,安装槽205的底壁设置有连通通道204,连通通道204形成取液管的进口。安装轴段101上设置有所述并行的两条连通通道:取液孔103和回气/喷液孔102。当然,也可以盖体上设置安装槽,取液管周壁上设置安装轴段。
上述实施例中,回气/喷液孔102的数量为两个,对称分布于取液孔103所处的轴向面两侧。这样,取液管2取液后顺时针或逆时针转动均可以实现回气和喷液,大大提高了使用便利性。
上述各实施例中,取液管2的管体包括相对端可拆卸连接的第一管体202和第二管体201,第一管体202另一端封闭,进口设置于第一管体,出口设置于第二管体201的另一端。第一管体202和第二管体201可以螺纹连接,也可以通过其他方式连接。
将管体设置为两段,可以降低加工工艺性。
上述各实施例的基础上,盖体1进一步地开设有开口向下的凹槽,凹槽位于安装孔之下,安装部为设置于凹槽周壁的密封螺纹部,取液通道1a为连通凹槽的底壁和安装孔内壁的通道。
上述各实施例中的取液装置还可以进一步包括密封帽6,密封帽6可拆卸地安装于取液管的出口2a端部。
此外,本发明还提供了一种药瓶组件,包括具有容液腔的药瓶体8,还包括上述任一项所述的取液装置,取液装置的盖体的安装部与所述药瓶体8的开口密封配合,取液管位于药瓶体8的外部。
如上所述,药瓶体8可以为可压缩式容积可变结构,以便当取液结束压缩所述药瓶体8时,取液管内部液体可自其出口2a喷出。
当然药瓶体8的结构不局限于本文上述描述,还可以为其他结构。
请参考图20和图21,本发明还提供了包括一种取液装置的药瓶组件的取液方法,包括以下步骤:
S01、将上述具体实施例中的药瓶组件灌装药液,常态下,却有关与药 瓶体同侧设置并且所述药瓶体开口朝上,所述取液管的出口朝上;
S02、取液时,将药瓶体相对取液管转动至第一位置,此时药瓶体倒置,取液通道与所述取液管进口连通,压缩药瓶体使药液流动至取液管的管体内部;
S03、待流至取液管内部的液体达到预设需求量时,药瓶体转动至第二位置,断开取液管与取液通道,此时取液管的出口通过取液管的进口、取液通道连通药瓶体的内腔,以使药瓶体回气;
S04、药瓶体回气结束后,旋转取液管至第三位置,此时所述药瓶体开口向上,且取液管的出口斜向下,压缩药瓶体以使取液管内部液体自出口喷至外部。
上述各实施例中的盖体1还可以设置防开齿结构104,与药瓶体8的瓶口齿结构配合。
本文中所提供的药瓶组件包括上述取液装置、取液方法是在上述取液装置的基础上实施例的,故药瓶组件和取液装置也具有取液装置的上述技术效果。
以上对本发明所提供的一种取液装置、具有该取液装置的药瓶组件及取液方法进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明进行若干改进和修饰,这些改进和修饰也落入本发明权利要求的保护范围内。
