本申请是于2009年4月22日提交的、序列号为12/427,965的美国专利申请的持续部分,其要求于2008年4月25日提交的、序列号为61/047,826的美国临时申请的利益与优先权,将所述每个申请的全部内容并入此处作为引用。
技术领域
本公开涉及用于混合且涂敷两种以上的成分的组件。更确切地说,本公开涉及一种供涂药器组件使用的喷射器喷头,其中所述喷射器喷头能够自洁。
背景技术
用于分配两种以上成分的涂药器组件是公知的。在医疗器械领域,这种组件典型地用于涂敷在伤口愈合中使用的生物胶粘剂、聚合物和其它合成材料。由于形成生物胶粘剂的成分的反应特性,因此直到即将涂敷溶液时才能混合成分。在涂敷之前将成分太早混合可导致混合物过早硬化,从而无法涂敷溶液。因此,在公知的涂药器组件中,两种以上的成分直到即将被涂敷前都分开保存。所述涂药器组件包括一个以上用于在涂敷前混合两种以上溶液的混合部件。混合部件可是被动的,例如,导管中的螺旋结构,或者相反可是主动的,例如,混合叶片或者推进器。一旦混合,溶液可通过针状输出而被涂敷,或者可通过喷射组件而被喷出。对于确保溶液如预期地发挥功效,两种以上成分在涂敷之前的完全混合很重要。
由于在工作过程期间可能需要间歇使用涂药器组件,故易于使涂药器喷头的出口堵塞。因此,多数涂药器组件都设置有一定数量的用于在发生喷头堵塞时的置换喷头。置换堵塞的涂药器喷头会中断工作过程的流程,这耗时且增加费用。
因此,具有能够自洁的涂药器喷头是有益的。
发明内容
因此,本发明提供了一种能够自洁的喷射器喷头。所述喷射器喷头组件包括含有出口的远端。该出口限定了至少一种在第一状态下的第一结构和至少一种在第二状态下的第二结构。远端可被构造成折曲和膨胀中的至少一种,以使出口从第一结构改变到第二结构。喷射器喷头组件还可包括近端,所述近端被构造成与分配组件可操作地接合。远端由允许折曲和膨胀中的至少一种的材料构成。远端的至少一部分可包括硅树脂。出口限定了正常运转期间的第一结构和当出口阻塞时的第二结构。远端可为径向地折曲和膨胀,以便从第一结构改变到第二结构。远端可为向远侧向外地折曲和膨胀中的至少一种,以便从第一结构改变到第二结构。远端可为径向地且向远侧折曲和膨胀中的至少一种,以便从第一结构改变到第二结构。出口可限定基本为圆形的开口,所述开口具有第一结构下的第一直径和第二结构下的第二直径。出口可限定开口,所述开口具有第一结构下的第一直径和第二结构下的较大直径。
此外,提供了自洁式涂药器。自洁式涂药器的一个实施例包括具有远端的喷射器喷头组件,所述远端含有出口。所述出口限定了至少一种在正常运转期间的第一结构和至少一种在出口至少部分阻塞时的第二结构。
在另一个实施例中,自洁式涂药器包括具有远端的喷射器喷头组件,所述远端含有出口,所述出口限定了至少一种在正常运转期间的第一结构和至少一种在出口至少部分阻塞时的第二结构。
在又一个实施例中,自洁式涂药器包括含有出口的喷射器喷头组件。所述喷射器喷头组件能够从出口清除阻塞物。
在另一个实施例中,自洁式涂药器包括限定了出口的喷射器喷头组件。所述喷射器喷头组件能够承受横截面几何形状的变化,以从出口清除阻塞物。

具体实施方式
首先参照图1,包括依照本公开的喷射器喷头组件的涂药器组件概括显示为涂药器组件10。涂药器组件10包括歧管或基部20、从歧管20延伸出的细长管30和放置在细长管30的远端30b上的喷射器喷头组件50。涂药器组件10还包括***件40,所述***件40被构造成容纳在喷射器喷头组件50的内部且位于细长管30的远端。
现在参照图2,歧管20包括基本为Y形的构件,该构件具有第一和第二近端延伸部22、24和远端延伸部26。近端延伸部22、24被构造成与第一和第二成分源(未显示),例如注射器,可操作地接合。如下文进一步详细论述的,远端延伸部26被构造成与细长管30可操作地接合。歧管20还包括第一和第二成分管路23、25。第一和第二成分管路23、25使第一和第二成分源与形成在细长管30内的第一和第二管腔33、35流体连通。尽管歧管20如图所示被构造成仅容纳两个成分源,但是可以预想到歧管20可被构造成容纳多于两个的成分源。
回头参照图1,细长管30可限定硅树脂、塑胶、聚合物或其它挠性材料的基本为固体的主体。如上所述,细长管30包括延伸其长度的第一和第二成分管腔33、35。由可延展材料构成的金属线36也延伸了细长管30的长度。金属线36被构造成在细长管30已经被弯曲或折曲后保持细长管30处于弯曲或折曲结构,以便适应给定的工作过程。将细长管30固定在歧管20的远端延伸部26上,以使第一和第二成分管腔33、35分别对准第一和第二成分管路23、25。可选择地,细长管30可一体地形成在歧管20的远端处。细长管30还可包括凹槽、棘爪、螺纹,或以其它方式被构造成与喷射器喷头组件50牢固接合。
现在参照图3至图6,喷射器喷头组件50限定了具有开放近端52a和基本闭合远端52b的基本为圆柱形主体52。开放近端52a被构造成容纳细长管30(图3)的远端30b。如下文将进一步详细讨论的,远端52b包括出口59,所述出口59被构造成喷射完全混合的溶液。喷射器喷头组件50可由硅树脂或其它合适的生物相容材料构成。
在一个实施例中,喷射器喷头组件50由从Momentive PerfomanceMaterials,Waterford,NY可获得的硅弹性体(例如),硅橡胶复合物和(一种液体硅橡胶)构成。通过测试,发现由具有70硬度计的硅树脂构成的喷射器喷头组件50在运转期间能够清除其自身的堵塞。可以预想到改***度计的其它硅树脂也能有效清洁自身或清除自身的堵塞。在喷射器喷头组件50堵塞期间,硅树脂的挠性特性允许喷射器喷头组件50在经受增加的压力的情况下折曲。喷射器喷头组件50的折曲去除了形成在其中的任何堵塞。此外,硅树脂的非润湿表面特性(疏水性)有助于防止喷射器喷头组件50堵塞。喷射器喷头组件50在运转期间清除自身堵塞的能力允许连续使用涂药器组件10,而无需一再更换喷射器喷头组件50。如此,可缩短工作过程的长度且排除了使用多个喷射器喷头组件的费用及不便性。
仍然参照图3至图6,喷射器喷头组件50包括第一腔室54、中间腔室56和末端腔室58。第一腔室54限定了用于容纳细长管30的远端30b的基本为圆柱形空腔。如在下文中所进一步详细论述的,第一腔室54构造成使得细长管30的远端30b被容纳为坚实地紧靠***件40。然而,可以预想到第一腔室54可构造成使得细长管30的远端30b向近侧离开***件40。中间腔室56限定了基本为圆柱形的空腔,所述基本为圆柱形的空腔被构造成容纳***件40。中间腔室56包括肋部或定位件56a,所述肋部或定位件56a用于将***件40(图6中虚线所示)保持在中间腔室56的正中。***件40包括放置在中间腔室56内的实心的基本为圆柱形的构件,以迫使第一和第二成分在由肋部56a形成的空间内在***件40周围流动。能够预想到***件40的尺寸可以制造成从中间腔室56向近侧延伸到第一腔室54中来确保***件40被容纳为坚实地紧靠细长管30的远端30b。
仍然参照图3至图6,末端腔室58限定了具有锥形远端部58a的基本为圆柱形的空腔。喷射器喷头组件50包括形成在其中并使中间腔室56与末端腔室58流体连通的狭槽57。狭槽57在与末端腔室58相切的切线和从所述切线逆时针旋转大约20度(20°)之间限定了从末端腔室58向外偏转角度的对置开口。如在下文中将进一步详细论述的,狭槽57将部分混合的第一和第二成分从中间腔室56内引导到末端腔室58内。尽管如图显示了一对对置开口,但可以预想到喷射器喷头组件50可仅仅包括单一的狭槽57(图6A),或者可选择地包括三个以上的狭槽57(图6A中虚线所示)。出口59被构造成将完全混合的溶液雾化为基本为锥形的喷雾。如图4所示,从近侧到远侧,出口59包括第一圆柱部59a、第二圆柱部59b和凹入部59c。然而,可以预想到出口59可形成为没有第二圆柱部59b。
现在参照附图来描述涂药器组件10的运转。在使用之前,将***件40容纳在喷射器喷头组件50的中间腔室56内。如上所述,将***件40设置为使得流过中间腔室56的流体被迫在由肋部56a之间形成的空间中在***件40周围。喷射器喷头组件50可选择性被地安装在细长管30的远端30b上。如上所述,歧管20可与细长管30一体形成,或者相反有必要在使用之前将细长管30手动固定到歧管20上,以确保第一和第二成分管路23、25与第一和第二成分管腔33、35对准。第一和第二成分源(未显示)分别紧邻地连接第一和第二近端延伸部22、24上。一旦将第一和第二成分源固定到歧管20上,则第一和第二成分源被激活,例如,注射器柱塞(未显示)抽空,以便迫使第一和第二成分分别在第一和第二成分管路23、25内流动。第一和第二成分分别流过第一和第二成分管路23、25,分别流过第一和第二成分管腔33、35,且进入到喷射器喷头组件50中。
从第一和第二成分管腔33、35中流出的第二和第二成分遇到保留在中间腔室56内的***件40。第一和第二成分管腔33、35相间隔,以使第一和第二成分可以在肋部56a和***件40之间形成的空间中在***件40周围流动。然后迫使第一和第二成分进入到狭槽57中,在狭槽57中它们被沿径向向内朝向末端腔室58引导。混合物通过狭槽57的流动在该混合物进入末端腔室58时使该混合物具有了漩涡运动。此后,随着完全混合的溶液以锥形喷雾被喷出出口59,该溶液被雾化。
转向图7至图11,本公开的替换实施例一般显示为涂药器组件110。涂药器组件110基本上与涂药器组件10相似,因此将仅仅描述二者之间的所涉及的不同之处。首先参照图7和图8,涂药器组件110包括被构造成容纳一对止回阀105的歧管或基部120、从岐管120延伸出的细长管130、以及放置于细长管130的远端上的喷射器喷头组件150。***件140容纳在喷射器喷头组件150内,而收缩导管160设置为围绕喷射器喷头组件150。
参照图7,第一和第二成分管路123、125从歧管120的远端延伸出。第一和第二成分管路123、125被构造成与贯穿细长管130的第一和第二成分管腔133、135流体连通。这种结构在歧管120和细长管130之间提供了更可靠的液封。
现在参照图9和图10,***件140基本与***件40相似,所述***件140包括被构造成容纳在喷射器喷头组件150内的基本为圆柱形的构件。如图所示,***件140包括在其第一端部上的半球形凹入部141,然后,为了便于制造和装配,可以预想到的是半球形凹入部141可形成在其两端上。将凹入部141构造成在混合物被喷出出口59之前在第一和第二成分的流动中形成湍流。
依然参照图9和图10,收缩导管160被设置为围绕喷射器喷头组件150以防止喷射器喷头组件150在运转期间的过度膨胀/折曲。收缩导管160还有助于将喷射器喷头组件150固定到细长管130上。收缩导管160可由特氟纶或其他合适的材料制成。
现在参照图11,喷射器喷头组件150基本与上文描述的喷射器喷头组件50相似,所述喷射器喷头组件150包括径向延伸的狭槽157。沟槽或环形凹入部157a形成在狭槽157周围。沟槽157a被构造成将部分混合的第一和第二成分引入狭槽157中。
现在参照图12至图14B,在喷射器喷头组件150的间歇使用期间,当保留在喷射器喷头组件150的出口159中的胶粘剂开始聚合或胶化时,可能堵塞或阻塞出口159。进行了一项关于将各种材料的喷射器喷头组件持续发挥作用的能力进行比较的研究,例如,在暂时停止喷射后继续喷射或清除自身的堵塞且继续喷射。所测试的材料包括C-Flex R70-005(30硬度计),DynaflexGLS 2711(43硬度计),Santaprene 281-64(60硬度计),Pellatbane(90硬度计)和GE Silicon(70硬度计)。研究结果显示由硅树脂制成的喷射器喷头组件能够重复清除自身的任何阻塞并且100%的时间继续喷射运转。请参见下表及图12。

表1
参照图13A和图13B,在喷射器喷头组件150运转期间,暂时停止喷射可导致形成可能堵塞出口159的“C”形的堵塞物或阻塞物。在出口159中出现“C”形堵塞物致使喷射器喷头组件150喷射喷雾至少部分失效,并在许多情况下,“C”形堵塞物完全阻塞流体通过出口159。无论是部分还是完全堵塞出口159,“C”形堵塞物都造成喷射器喷头组件150内的压力增大。如图所示,由“C”形堵塞物产生的压力增大使喷射器喷头组件159如由箭头“A”所示沿径向向外膨胀和/或折曲。此处所使用的,膨胀是指材料的拉伸,而折曲是指材料的变形。喷射器喷头组件150的径向膨胀和/或折曲改变出口159的结构。
如图所示,喷射器喷头组件150的径向膨胀和/或折曲致使出口159沿着其至少一部分增大直径。基于径向膨胀和/或折曲的程度,喷射器喷头组件150的末端腔室158也沿着其至少一部分增大直径。出口159直径的增大允许“C”形堵塞物穿过出口159。一旦出口159的“C”形堵塞物被清除,则喷射器喷头组件150内的压力增大会消失,并且出口159恢复到其初始状态的未膨胀/未折曲的结构。如此,喷射器喷头组件150能够自洁“C”形堵塞物,自洁意味着能够清除出口159的“C”形堵塞物而无需附加的外界影响。尽管图示表明一致的或对称的径向膨胀/折曲,但应该意识到喷射器喷头组件150的结构允许喷射器喷头组件150的不对称的膨胀和/或折曲。如此,出口159可经受不对称的膨胀/折曲,例如,拉长。
现在转向图14A和图14B,由“C”形堵塞物在喷射器喷头组件150内产生的压力增大可额外地,或者相反,致使喷射器喷头组件150在远侧或纵向上膨胀和/或折曲,如箭头“B”所示。喷射器喷头组件150的纵向膨胀和/或折曲致使出口159的结构改变(如虚线显示)。如图所示,喷射器喷头组件150的纵向膨胀和/或折曲致使出口159沿着其至少一部分增大直径。基于径向膨胀和/或折曲的程度,喷射器喷头组件150的末端腔室158也可沿着其至少一部分增大或减小直径。
尽管未图示,但是喷射器喷头组件150的中间腔室156可在喷射器喷头组件150的径向和/或纵向膨胀/折曲期间承受结构的改变。在膨胀和/或折曲期间,当将“C”形堵塞物从出口159清除掉时,第一和第二成分冲撞***件140的力量保持***件140的远端140a坚实地紧靠中间腔室156的远端,从而确保将第一和第二成分被正确引导到末端腔室158中。
已进行了将各种结构的喷射器喷头组件150的特性与已知的喷射器喷头组件(未显示)进行比较的第二项研究。研究结果显示包括置于其周围的特氟纶热收缩导管160(图7)的喷射器喷头组件150改良了喷射器喷头组件150的开启/停止功能。此外,发现在细长管130的远端130b和***件140之间设置1至2mm的小间隔证明不会改进喷射特性。
尽管本文已经参照附图描述了本公开的图示实施例,但是应该理解的是本公开不限于那些明确的实施例,并且对本领域的技术人员而言其中各种其它的改变和修正都是有效的,不会脱离本公开的范围或精神。
