[0005]细长轴可包括沿其长度延伸的挠性线。歧管和细长部件可整体形成。中间腔室可包括用于使所述插入物与所述腔室壁保持间隔关系的肋。出口可被配置作为从喷嘴组件喷出混合物的喷雾器。涂敷组件可进一步包括形成在所述中间腔室和所述最终腔室之间的至少第一槽，所述至少第一槽被配置为沿径向向内引导所述至少第一和第二组分。在一个实施例中，喷嘴组件包括三个或更多的槽。至少第一槽可被配置为使所述至少第一和第二组分在所述最终腔室内打漩。插入物可包括被配置为容纳在中间腔室中的大体的圆柱体。歧管可包括大体的Y形部件。细长轴和/或插入物可以由硅树脂组成。细长轴可以是挠性的。
[0006]还提供了一种用于混合至少第一和第二组分的系统。所述系统包括：至少第一和第二组分源；歧管，其被配置为可操作地与至少第一和第二组分源接合，歧管包括通过其中的至少第一和第二组分通道；细长轴，其从歧管向远侧延伸，细长轴包括沿其长度延伸的至少第一和第二组分腔，至少第一和第二组分通道与至少第一和第二组分通道处于液体连通；喷嘴组件，其限定第一腔室、中间腔室和最终腔室，其中第一腔室被配置为容纳细长轴的远端，第二腔室被配置为容纳插入物，而最终腔室被配置为在混合物从限定在喷嘴组件的远端上的出口被喷出之前容纳至少部分地混合的至少第一和第二组分。

具体实施方式
[0021]首先结合图1，根据本公开的包括喷嘴组件的涂敷组件通常被表示为涂敷组件10。涂敷组件10包括歧管或基部20、从歧管10延伸出的细长轴30和定位在细长轴30的远端30b上的喷嘴组件50。涂敷组件10进一步包括插入物40，其被配置为容纳在喷嘴组件50和细长轴30的远端之中。
[0022]现在结合图2，歧管20包括具有第一和第二近侧延伸部22、24和远侧延伸部26的大体的Y形部件。近侧延伸部22、24被配置为可操作地与例如注射器的第一和第二组分源(未图示)接合。如下面将进一步详细讨论的，远侧延伸部26被配置为与细长轴30可操作地接合。歧管20进一步包括第一和第二组分通道23、25。第一和第二组分通道23、25将第一和第二组分源与形成在细长轴30中的第一和第二腔33、35处于液体连通。如图所示，当歧管20被配置为仅容纳两个组分源时，可以预想的是，歧管20可以被配置为容纳多于两个的组分源。
[0023]再结合图1，细长轴30限定了硅树脂、塑料、聚合物或其它的挠性材料的实质的固体。如上所述，细长轴30包括沿其长度延伸的第一和第二组分腔33、35。由可延展材料组成的线36也沿细长轴30的长度延伸。线36被配置为在细长轴30已经挠曲或弯曲之后使细长轴30保持在挠曲或弯曲形态以适应给定的操作。细长轴30固定到歧管20的远侧延伸部26上以使得第一和第二组分腔33、35分别与第一和第二组分通道23、25对准。可选择地，细长轴30可以与歧管20整体地形成。细长轴30可以进一步包括凹槽、定位槽或被配置为可靠地与喷嘴组件50接合。
[0024]现在结合图3至图6，喷嘴组件50限定了具有开口近端52a和实质闭合远端52b的大体的圆柱体52。开口近端52a被配置为容纳细长轴30的远端30b(图3)。如下一步将进一步详细讨论的，远端52b包括被配置为喷出完全混合溶液的出口59。喷嘴组件50可以由硅树脂或其它适合的生物适应材料组成。
[0025]在一个实施例中，喷嘴组件50由硅树脂弹性体组成，例如，可从纽约，沃特福德，迈图高新材料公司(Momentive Performance Material，Waterford，NY)获得的硅橡胶化合物
Figure A20091013724300071
II 94706或者液体硅橡胶
Figure A20091013724300072
6071。通过测验，已经发现由硅树脂组成的喷嘴组件50具有70测定硬度(durometer)，在运行期间，喷嘴组件50能够使自身不被堵塞。在喷嘴组件50堵塞时，硅树脂的挠性特征使喷嘴组件50在所承受的增加的压力下弯曲。喷嘴组件50的挠性使得可能形成于其中的任意堵塞畅通。此外，硅树脂的非浸润表面特性(疏水性)可有助于防止喷嘴组件50的堵塞。喷嘴组件50在运行期间疏通自身的能力允许涂敷组件10的持续使用而无要重复更换喷嘴组件50。这样，能够减小过程长度并消除使用多个喷嘴组件的费用。
[0026]仍参考图3至图6，喷嘴组件50包括第一腔室54、中间腔室56和最终腔室58。第一腔室54限定了用于容纳细长轴30的远端30b的大体的圆柱形空腔。如在下面进一步详细描述的，第一腔室54被配置为使得细长轴30的远端30b以平齐地压靠插入物40的方式被容纳。然而，可以预想的是，第一腔室54可以被配置为使得细长轴30的远端30b与插入物40邻近地隔开以便形成用于第一和第二组分的最初混合空间。中间腔室56限定了大体的圆柱形空腔以容纳插入物40。中间腔室56包括肋或定位件56a以保持插入物40在中间腔室56内位于正中心。插入物40包括位于中间腔室56中的实心的大体的圆柱形部件以推动第一和第二组分在由肋56a形成的空间中绕插入物40流动。在可选择的实施例(图3A)中，插入物40’可以从中间腔室56向远侧延伸到第一腔室54中，从而在插入物40’的近端40a’周围在细长轴30的远端30b和中间腔室56之间产生最初混合空间41’。这样，从第一和第二组分腔33、35中流动的第一和第二组分可以在进入中间腔室56之前开始混合。插入物40、40’可以由硅树脂或其它适合的生物适应材料组成。
[0027]仍结合图3至图6，最终腔室58限定了具有锥形远侧部58a的大体的圆柱形空腔。喷嘴组件50包括形成于其中的槽57，所述槽57使中间腔室56和最终腔室58处于液体连通。槽57限定了在正切于最终腔室58的线和从切线逆时针成大约二十度(20°)之间从最终腔室58向外倾斜的相对开口。如在下面将详细描述的，槽57将部分混合的第一和第二组分从中间腔室56中引导到最终腔室58中。尽管所示为一对相对开口，但是可以预想的是，喷嘴组件50可以仅包括单个槽57(图6A)，或者可选择地包括三个或更多的槽57(图6A中的虚线所示)。出口59被配置为将完全混合的溶液雾化成锥形喷雾。如图所示，出口59从近侧到远侧包括第一圆柱形部59a、第二圆柱形部59b和凹进部59c。然而，可以预想的是，出口59可以被形成为不具有第二圆柱形部59b。
[0028]下面将结合图来描述涂敷组件10的运行。在使用之前，插入物40容纳在喷嘴组件50的中间腔室56中。如上所述，插入物40被定位为使得穿过中间腔室56的液体在由肋56a形成的空间中绕插入物40被推动。喷嘴组件50可选择地容纳在细长轴30的远端30b上。如上面所讨论的，歧管20可以与细长轴30整体地形成，或者相反地，在使用之前需要手动地将细长轴30固定到歧管20上，确保第一和第二组分通道23、25与第一和第二组分腔33、35对准。接着第一和第二组分源(未图示)分别连接到第一和第二近侧延伸部22、24。一旦固定到歧管20，第一和第二组分源可以被致动，例如，压下注射器活塞(未图示)，以使第一和第二组分通道23、25中的第一和第二组分分别开始流动。第一和第二组分流过第一和第二组分通道23、25，分别通过第一和第二组分腔33、35，然后进入喷嘴50中。
[0029]从第一和第二组分腔33、35中流动的第一和第二组分遇到保持在中间腔室56中的插入物40。第一和第二组分腔33、35被分开以使得第一和第二组分可以在由插入物40和喷嘴50之间的肋56a形成的空间中绕插入物40流动。最初混合的第一和第二组分然后被推入槽57中，在此处它们沿径向向内朝着最终腔室58被引导。随着混合物进入最终腔室58，通过槽57的混合物的流动使混合物产生打漩运动。之后，完全混合的溶液随着其通过出口59喷出而被雾化成锥形喷雾。
[0030]转到图7至图10，本公开的可选实施例通常被表示为涂敷组件110。涂敷组件110大体类似于涂敷组件10，因此将仅对它们之间的不同进行描述。首先结合图7和图8，涂敷组件110包括被配置为容纳一对止回阀105的歧管或基部120、从歧管120延伸出的细长轴130以及定位在细长轴130远端上的喷嘴组件150。插入物140容纳在喷嘴组件150中并且收缩管160容纳在喷嘴组件150周围。
[0031]结合图7，第一和第二组分通道123、125从歧管120的远端延伸出。第一和第二组分通道123、125被配置为与通过细长轴130延伸的第一和第二组分腔133、135处于液体连通。所述结构允许在歧管120和细长轴130之间更可靠的液体密封。
[0032]现在结合图9和图10，插入物140大体上类似于插入物40，包括被配置为容纳在喷嘴组件150中的大体的圆柱形部件。如图所示，插入物140包括在其第一和第二端上的半球状凹部141，然而可以预想的是，半球形凹部141可以形成在其单个端上。凹部141被配置为当第一和第二组分遇到插入物140时使第一和第二组分的流动产生湍流，从而帮助组分混合。
[0033]仍结合图9和图10，收缩管160容纳在喷嘴组件150周围以防止喷嘴组件150在运行期间过度径向膨胀/弯曲。收缩管160也可以帮助将喷嘴组件150固定到细长轴130上。
[0034]现在结合图11，喷嘴组件150大体类似于喷嘴50，如上文所述，包括径向延伸的槽157。沟状或环形状凹部157a形成在槽157的周围。沟157a被配置为将部分混合的第一和第二组分引导到槽157中。
[0035]尽管此处已经结合附图描述了本公开的示例性实施例，但是应该理解的是，本公开不局限于这种精确的实施例，在不脱离本公开的范围和实质的情况下，本领域的技术人员可以对其进行各种其它的修改和改进。
