Description

喷雾给药装置和包括该装置的喷雾给药系统 技术领域
本申请涉及一种给药装置,特别是一种能够与注射器配合使用并以喷雾形式向人体递送药物的给药装置。
背景技术
注射器是医疗领域中常用的医疗器具,用于将药物诸如人体中,以进行疾病治疗、疫苗植入等操作。目前市场上存在一种与注射器配合使用的喷雾给药装置,在将药液吸入到注射器中之后,该喷雾给药装置能够配合到注射器上,然后将喷雾给药装置的喷嘴对准鼻腔、口腔或其它适于给药的人体部位,通过推动注射器,使药液雾化并递送到人体中。与传统的注射器给药相比,这种喷雾给药装置能够均匀地将药液递送到需要的部位,而且可以减少对人体产生的创伤。
在应用过程中,发现现有的喷雾给药装置还存在一些问题。例如,在推动注射器以递送药液时,注射器内的压力会快速增大,造成喷雾给药装置和注射器之间的连接松动,导致在两者之间产生泄漏,严重的会导致喷雾给药装置与注射器互相脱离,甚至会将喷雾给药装置喷飞,产生安全隐患。
又比如,在某些应用场合,例如对使用人的鼻腔进行喷射时,喷雾给药装置和注射器的朝向不合理,注射器采取前高后低的姿态,这样的话位于注射器前端的将是空气,首先被喷出的也是空气,然后才是药液被喷出。因此,残留在喷雾给药装置和注射器中的药液会比较多,导致用药量不准确,同时也会造成药液的浪费。
此外,在对鼻腔进行给药时,需要对两个鼻腔分别进行给药。这样的操作比较繁琐,而且还难以保证对两个鼻腔的给药量相等,有时甚至两个鼻腔的给药量有较大差异。
因此,存在对喷雾给药装置的结构进行进一步改进的需求,以克服上述现有的喷雾给药装置所存在的技术问题。
发明内容
本发明是为解决以上所述现有技术所存在的技术问题而作出的。本发明的目的是提供一种结构改进的喷雾给药装置,其在喷雾给药装置与注射器相套接的时候避免它们互相脱开或在它们之间发生泄漏的问题。另外,本发明还通过对喷雾给药装置的结构进行改进,实现对该装置和注射器中药液的充分喷射。进一步地,该改进结构的喷雾给药装置还能实现对两个鼻腔的均匀给药。
本发明的喷雾给药装置包括:
套管,该套管形成有内腔,内腔能够容纳注射器的针筒;以及
至少一个喷嘴,该喷嘴设置在套管的前端,并且与套管的内腔连通;
其中,该喷嘴的轴线方向相对于套管的轴线方向成角度。
在上述结构中,喷嘴的轴线方向相对于套管的轴线方向成角度,因而相对于插入在套管中的注射器的轴线方向也成同样的角度。这样的话,当使用喷雾给药装置给鼻腔输送药液时,注射器将呈前低后高的姿态。此时,药液会聚集在注射器的前端,而在药液后部会有气体。当推送药液时,该气体会被压缩,其压缩力会提供额外的推动药液的动力。而且,在推送药液的结尾时,该压缩气体会起到吹扫药液的作用,从而将残留的药液推尽。
本发明的另一种结构中,喷雾给药装置包括:
套管,套管形成有内腔,内腔能够容纳注射器的针筒;
至少一个喷嘴,喷嘴设置在套管的前端,并且与套管的内腔连通;以及
指压扣板,指压扣板形成在套管的后端或邻近后端。
指压扣板的设置可在推送药液时保证喷雾给药装置和注射器保持在一起,减少或消除它们之间的药液泄漏,还能防止喷雾给药装置被喷飞。
本发明的又一种结构中,喷雾给药装置包括:
套管,套管形成有内腔,内腔能够容纳注射器的针筒;以及
两个喷嘴,两个喷嘴设置在套管的前端,并分别位于套管的前端的左右两侧,并且两个喷嘴与套管的内腔连通。
两个喷嘴的设置允许对两个鼻腔同时送药,确保递送给两个鼻腔的药液量相同。
较佳地,喷嘴包括弯管,弯管的一端连接在喷雾给药装置的前端,弯管的另一端中插入有喷嘴芯,并且喷头套设在弯管的另一端上。更佳地,弯管为 波纹管,从而允许对弯管的弯曲角度进行调节。
较佳地,可以包括一个喷嘴,其中,喷嘴包括喷头和容纳在喷头中的喷嘴芯,其中,喷头一体形成于套管上。
较佳地,喷嘴包括弯管和喷嘴芯,弯管的一端连接在喷雾给药装置的前端,弯管的另一端中形成有凸柱,喷嘴芯从弯管的另一端套设到凸柱上。其中,该弯管较佳地可相对于套管转动,从而允许调节喷嘴相对于套管的角度。进一步较佳地,弯管可以是波纹管,以有助于弯管相对于套管的转动。
当然,喷嘴相对于套管角度固定的情况也在本发明的范围之中,例如可通过切口-凸片的配合结构来固定喷嘴相对于套管的角度。
较佳地,套管上形成有观察部,透过观察部能够看到注射器。这样,该观察部可便于使用人控制推送的药液量。
较佳地,观察部为形成在套管上的镂空部或者透明部分。
较佳地,喷嘴包括喷头,喷头上形成有吸气通道。该吸气通道允许使用人在施加药液时吸入空气,从而有助于更深地施加药液。而且,该吸气通道还可使使用人呼吸顺畅。
具体地,吸气通道由以下结构中的至少一种形成:吸气口和吸气槽。
还涉及一种喷雾给药系统,该喷雾给药系统包括如上所述的喷雾给药装置以及注射器,注射器能够插入到喷雾给药装置的套管的内腔中。
较佳地,还包括限位卡子,限位卡子可拆卸地安装在注射器的柱塞上。

具体实施方式
为了便于理解本发明,下面将结合附图对本发明的具体实施方式进行详细描述。应当理解,附图中所示的仅仅是本发明的较佳实施例,其不应理解为对本发明的范围的限制。本领域的技术人员可以在附图所示的实施例的基础上对本发明进行各种显而易见的修改、变型、等效替换,并且在不相矛盾的前提下,以下所描述的不同实施例中的技术特征可以互相任意地组合,而这些都落在本发明的范围之内。
在以下的对本发明的具体描述中,所使用的诸如“前”、“后”之类的表示方向和朝向的用语是在喷雾给药装置和注射器在使用过程中以使用人为参照而言的。其中,“前”指的是远离使用人的一侧,“后”指的是靠近使用人的一侧。
<第一实施例>
图1~6示出了本发明的第一实施例的喷雾给药装置110以及与该喷雾给药装置110一起使用的注射器120。图2示出了该喷雾给药装置110和注射器120的组件的俯视图。
喷雾给药装置110包括套管111,注射器120的针筒121能够插入到套管111的内腔中,如图3中示意性地示出的那样。
图4和5分别示出了沿图2中的线A-A和B-B得到的剖视图。如图4中所示,在喷嘴130内设置有喷嘴芯131,来自注射器120的药液经由该喷嘴芯131而被雾化。
图6a示出了喷雾给药装置110的分解立体图,以更好地显示出该喷雾给药装置110的结构。可以看到,在喷雾给药装置110的套管111的后端或在后端附近形成有指压扣板112。当使用人用拇指推压注射器120的柱塞122以对注射器120中的药液进行推送时,使用人的食指和中指可扣住该指压扣板112。较佳地,在套管111上形成有镂空部113,该镂空部113的设置使得使用人能够看到被套在套管111中的注射器120的针筒121上的刻度,从而有助于使用人控制所推送的药液量。
作为对镂空部113的替代,也可以采用透明材料来形成喷雾给药装置110的一部分,或者喷雾给药装置110完全有透明材料制成,例如由透明的塑料材料制成,等等。
指压扣板112可以采用各种合适的形状,例如多边形、圆形等,这些都在本发明的范围之中。
在套管111的前端上设置有两个喷嘴130。具体来说,在套管111的该前端的左右两侧分别形成有侧开口114,即在该前端上形成有两个侧开口114。该侧开口114的开口方向与套管111的轴线方向成角度,较佳地垂直于该轴线方向。
在每个侧开口114上连接有喷嘴130的弯管132。举例来说,侧开口114上形成有凸环结构,相对应地,在弯管132的靠近侧开口114的一端的内表面上形成有凹槽结构。在将弯管132安装到侧开口114上时,凸环结构和凹槽结构之间形成卡扣配合,实现弯管132与侧开口114之间的连接。喷嘴芯131插入在弯管132另一端内,喷头133覆盖在弯管132的该另一端上,由此组装形成喷嘴130。如从图5中更清楚地看出的,在组装好之后,将喷嘴130布置成其纵向轴线相对于套管111的纵向轴线成角度,或者说两根纵向轴线不在一条直线上。并且,凸环结构和凹槽结构之间的卡扣配合允许弯管132相对于套管111转动,从而以调节喷嘴130的纵向轴线相对于套管111的纵向轴线所成的角度。
弯管132和侧开口114之间的连接也可通过其它方式连接,例如通过螺纹结构互相啮合,等等。还可以通过其它附加的或替代的结构来实现弯管132相对于套管111的转动,例如将在之后的实施例中所描述的。
弯管132和侧开口114之间也可以是不可转动地互相固定。
例如,如图6b和6c中所示的,在侧开口114的位置处形成有缺口部134,而在弯管132的与侧开口114相连接的一端上形成有凸片135,在将弯管132连接到侧开口114上时,凸片135配合到缺口部134中。通过缺口部134和凸片135之间的相互作用,使得弯管132不能转动,进而使弯管132相对于套管111的角度固定。缺口部134和凸片135的设置部位也可互换,即,缺口部134可形成在弯管132上,而凸片135则形成在侧开口114的对应位置处。
下面将描述喷雾给药装置110的使用方法。
使用人先用注射器120从药瓶中抽取药液。然后,将注射器120的针头移除,将注射器120的针筒121插入到套管111的内腔中。然后,使用人推动注射器120的柱塞122,将针筒121中的药液推到喷嘴130中,药液在喷嘴130中被雾化。经喷嘴130雾化的药液从喷嘴130的喷头133喷出,并可施加到诸如患者的鼻腔、口腔等部位。
在推送药液的过程中,使用人一方面抵推柱塞122(例如用拇指),另一方面扣住套管111上的指压扣板112(例如用食指和中指)。这样,在推送药液的过程中,保持注射器120抵靠在喷雾给药装置110中,从而可减少甚至消除发生在喷雾给药装置110与注射器120之间的药液泄漏,喷雾给药装置110也不会因为被推出的药液的压力而被喷飞。
进一步地,所示第一实施例的喷雾给药装置110具有两个喷嘴130,因此尤其适用于对鼻腔给药。即,在给药时,可将两个喷嘴130分别对准患者的两个鼻孔。两个喷嘴130可以制作成基本相同,这样的话在推动柱塞122时,可以同时向两个喷嘴130提供药液并生成雾化药液,且喷出的雾化药液能够保持基本相同。
另外,由于喷嘴130的纵向轴线与套管111的纵向轴线(同时也是注射器120的纵向轴线)成角度,因此当将两个喷嘴130对准并插入到患者的鼻孔中时,注射器120将呈前低后高的姿态。这样,在给药时,药液将集中在注射器120的前端,而在药液和柱塞122的前端之间会有一定量的气体。此时,若推动柱塞122,则柱塞122的前端和药液之间的气体会被压缩,该压缩的气体对药液产生附加的推动力,从而有助于更加快速地将药液推出。而在推药程序的结尾,压缩空气将被推出,在被推出的过程中,该压缩空气的压力可以将残留在喷雾给药装置110、注射器120和喷嘴130中的药液都推出,从而实现药液的完全喷射干净。
<第二实施例>
图7~11示出了本发明的第二实施例的喷雾给药装置210和注射器220的组件的结构及其变型结构。其中,与第一实施例相同或对应的特征部分用相 同或类似的附图标记来表示,并且以下的公开内容中主要描述与第一实施例不同的特征,而不对相同的特征再作详细描述。除非有相反的描述,第一实施例中描述的特征同样适用于第二实施例。
如图7和8中所示的,与注射器220一起使用的喷雾给药装置210具有单个喷嘴230。该喷嘴230的纵向轴线与喷雾给药装置210的纵向轴线基本一致,或者说成一条直线。喷嘴230包括喷头233和容纳在喷头233中的喷嘴芯231。在图中所示的较佳结构中,喷头233可与喷雾给药装置210的套管211一体形成。当然,喷头233也可与套管211分开形成,然后再安装到一起。
与第一实施例相同,在套管211的后端形成有指压扣板212,在推送注射器220中的药液时,使用人可以在推动注射器220的柱塞222的同时扣住指压扣板212,从而将喷雾给药装置210和注射器220保持在一起。
图9~11示出了对本发明的第二实施例的一种变型结构的示意图。具体里来说,在注射器220上安装限位卡子240,用于辅助计量所喷出的药液量。具体来说,该限位卡子240安装在柱塞222上。图11示出了该限位卡子240的一个示例性结构。
如图10所示,在初始位置,柱塞222的长度比限位卡子240的长度多出H1,因此,允许朝着前端的方向推动柱塞222。当将柱塞222向前推距离H1之后,限位卡子240将被卡在针筒221和柱塞222之间,此时限位卡子240阻止继续向前推动柱塞222。此时,完成对一个鼻腔的送药。接着,在对另一个鼻腔进行送药时,移除限位卡子240,从而可向着前端的方向继续推动柱塞122,直到将药液推尽,例如图10中所示的将柱塞222向前推距离H2,以推尽药液。
限位卡子240的设置将有助于对注射器220中的药液进行分配,以确保递送到两个鼻腔中的药液量基本相等。
<第三实施例>

第三实施例中的喷雾给药装置310能与注射器320配合使用,并且在喷雾给药装置310的前端具有单个喷嘴330。与第二实施例不同的是,第三实施例的喷雾给药装置310的喷嘴330的轴线方向与喷雾给药装置310主体(即其套管)的轴线方向成角度,如图13中所示的。
喷嘴330也包括喷嘴芯331、容纳喷嘴芯331并连接于喷雾给药装置310的主体的弯管332、以及套设在喷嘴芯331和弯管332上的喷头333。

在第四实施例中,喷雾给药装置410包括两个喷嘴430,这两个喷嘴430各自包括喷嘴本体432,且该喷嘴本体432与喷雾给药装置410一体地形成,如能够从图16所示的剖视图中更加清楚地看出的。较佳地,喷嘴430的喷嘴本体432整体呈弧形,以便于制造。
喷嘴430还包括喷嘴芯431,该喷嘴芯431插入到喷嘴本体432中。
该一体形成的喷嘴430的结构有助于简化结构,减少零件数量。
<第五实施例>
图17示出了本发明的第五实施例的喷雾给药装置510。其中,与第一至第四实施例相同或对应的特征部分用相同或类似的附图标记来表示,并且以下的公开内容中主要描述与第一至第四实施例不同的特征,而不对相同的特征再作详细描述。除非有相反的描述,第一至第四实施例中描述的特征同样适用于第五实施例。
在第五实施例的喷雾给药装置510中,喷嘴530包括波纹管532,以用作 喷嘴530的喷嘴本体,并且,该波纹管532连接到喷雾给药装置510的本体上。
使用波纹管532作为喷嘴530的本体,可方便成型,在成型时该波纹管532可以做成直的,在使用时可根据需要弯折到所要的弯度。另外,该波纹管532还允许调整其弯曲角度,从而可适用于多种应用场合。
<第六实施例>
图18~20示出了本发明的第六实施例的喷雾给药装置610。其中,与第一至第五实施例相同或对应的特征部分用相同或类似的附图标记来表示,并且以下的公开内容中主要描述与第一至第五实施例不同的特征,而不对相同的特征再作详细描述。除非有相反的描述,第一至第五实施例中描述的特征同样适用于第六实施例。
喷雾给药装置610包括作为其本体部分的套管611,在套管611的后端形成有指压扣板612,在套管611的前端安装有喷嘴630。与第一实施例类似,该喷嘴630可通过诸如卡环-凹槽配合(如图中所示的)、螺纹连接之类的方式连接到套管611。
在第六实施例中,喷嘴630包括弯管632和插入在该弯管632中的喷嘴芯631。图20示出了喷嘴630的剖视图,其中显示,在弯管632中形成有凸柱633,插入在弯管632中的喷嘴芯631能够套设在该凸柱633上,从而实现喷嘴芯631在弯管632的固定。
上述结构的喷嘴630可应用于以上所述的第一~第五实施例的喷雾给药装置中。

如图21~22b所示的,在第七实施例的喷雾给药装置710中,其喷嘴的 喷头733上形成有至少一个、较佳地多个吸气口734。该吸气口734围绕着喷头733的周向布置。在图22a和22b所示的一种示例中,吸气口734呈大致矩形。
通过设置吸气口734,当使用喷雾给药装置710对使用人的鼻腔进行给药时,吸气口734提供了吸入空气的通路。所吸入的空气有助于将雾化的药液带入到鼻腔深处,进而有利于鼻腔黏膜对药液的吸收。而且,该吸气口734的设置还可在给药的过程中保持使用人呼吸顺畅,这对于小孩等来说尤其有用。
图23~24b示出了第七实施例的喷雾给药装置710的一种变型结构。其中,在喷头733’上设置有若干个呈圆形的吸气口734’。
