Description

用于双管注射器的可更换式手动混合连接器 技术领域
本发明涉及牙科材料输送系统及其配件，尤其涉及用于双管注射器的可更换式可更换式手动混合连接器。
背景技术
牙医在进行牙科治疗过程中，常需要使用双管注射器以1∶1的比例精确混合两种不同的牙科材料。此类牙科材料往往成本较高，并且在混合前应避免污染。为了确保牙科材料的良好混合，常使用一种用于双管注射器的自动混合器，其连接在双管注射器的末端，能够将从双管注射器挤出的材料自动混合。但是，为了实现两种不同材料的充分混合，自动混合器需要预留足够的材料混合空间(通常是预留较长的混合行程，使得材料在通过该混合行程期间实现充分混合)，以便使两种材料在从自动混合器中挤出之前已经在自动混合器内部实现均匀混合。这样，在治疗过程结束时，在自动混合器的材料混合空间内会残留一部分已经混合的材料。这些材料无法在治疗过程中使用，并且由于已经与外界接触，因而也不能在下一次治疗中使用，而只能在下一次治疗过程之前挤出并抛弃，这造成了一定程度的浪费，尤其是当每次的材料用量都非常少的时候。对于许多牙医而言，需要一种能够减少材料浪费的可更换式手动混合连接器。
已经开发出了一些能够满足以上要求的可更换式手动混合连接器。如由美国专利US 8,100,295 B2已知一种用于双管注射器的可更换式手动混合连接器。其通过滑扣结构结合在双管注射器上，并且可以通过按压变形而从双管注射器脱离。该可更换式手动混合连接器不需要设置大的材料混合空间，牙科材料从双管注射器挤出后通过该手动混合连接器，之后由牙医手动进行混合。该可更换式手动混合连接器的缺陷在于，按压变形使得混合器整体形状发生变化并造成混合器内部压力变化，可能导致牙科材料溢出并污染。此外，该混合器的结构依然相对复杂，制造成本相对较高。
市场上还有一种手动混合连接器，其包括盖和双管座两部分。双管座利用凸棱-凹槽结构旋转接合在双管注射器上，盖插接在双管座上并可以拔出。但是，双管座与双管注射器之间的该接合是不可逆的，因此该手动混合连接器无法进行更换，或者强行更换可能造成手动混合连接器和双管注射器损坏，并可能导致材料污染。此外，由于盖能够从双管座拔出，因此应该确保盖在再次与双管座接合时依然保持相同的朝向，从而避免盖内残留的材料错误地接触到不同的材料而使得双管注射器内的材料被污染。而上述混合器产品的盖与双管 座之间虽然有防错设计，但是该设计在外观上并不明显，仅在盖的底部一侧有很小的一个凸棱作为指向标记，在实际操作中容易被操作人员忽视，造成不必要的误插。
本领域对于能够弥补以上现有技术缺陷的新型可更换式手动混合连接器存在着需求。
发明内容
本发明提出了一种新型的用于双管注射器的可更换式手动混合连接器，其通过更加简单的结构实现了用于手动混合双管注射器内不同牙科材料的装置。根据本发明的一个方面，涉及一种用于双管注射器的可更换式手动混合连接器，其包括盖和双管座，双管座具有上管和下管，用于与双管注射器的管口形成连通通道，其特征在于，双管座通过弹性卡扣装置与形成在双管注射器顶部的凸缘形成接合。

具体实施方式
以下将结合附图描述本发明的非限制性示范实施例及其有益的技术效果。
图1示出了根据本发明的可更换式手动混合连接器与双管注射器连接在一起的透视图。如图中所示，可更换式手动混合连接器1与双管注射器2接合在一起，从而双管注射器2中的材料能够通过可更换式手动混合连接器1挤出，然后进行混合。可更换式手动混合连接器1与双管注射器2之间通过弹性卡扣结构连接(后文将详细描述)。并且，在可更换式手动混合连接器1上，可以看到盖与双管座之间有明显的防错连接设计，有关该防错连接设计也将在后文进行详细描述。
图2示出了根据本发明的可更换式手动混合连接器在与双管注射器连接在一起的情况下将盖3从双管座9取下的透视图。该视图示出了根据本发明的可更换式手动混合连接器的工作状态。将盖3从双管座9上取下，即可从双管注射器2通过双管座9上的双管出口挤出牙科材料并进行手动混合。在注射器内的材料没有用完的情况下，可以将盖3重新盖回双管座9，避免材料长时间与外界接触造成污染，并且为下一次手动混合做好准备。双管座9的上管和下管构成的管道长度非常小，因而管道内残留的材料量非常小。且由于盖3的封闭作用，管道内残留的材料并不会被污染，可以直接应用于下一次治疗过程。
图3和图4从不同的角度示出了根据本发明的可更换式手动混合连接器的分解视图，其详细示出了盖3与双管座9之间的接合特征。如图中所示，盖3通过位于其一侧内部的凸棱5和相对一侧的V形开口6与双管座9上对应的接合凹槽20以及三角形突起15形成配合，从而确保盖3与双管座9之间始终以相同的相对方位接合而不会发生误插，这有效地防止了盖3内部残留的牙科材料与双管座9的上管10a，10b的管口11a，11b处的牙科材料发生交叉污染。V形开口6与三角形突起15在外观上特征明显，能够轻易辨识，也能够在弱光条件下或不便仔细观察时仅凭触摸轻易识别，从而可以更加有效地防止操作人员在使用过程中以错误的方向插接盖3与双管座9。结合图1和图2所示，可以看到，双管座9通过弹性卡扣装置14a，14b与双管注射器接合，该接合特征在后文还将详细描述。此外，观察图4中所示，还会看到在双管座9的底部设置了凸棱16，该凸棱16起到双管座9与双管注射器2之间的防错连接的作用，其也将在后文进一步详述。
图5示出了盖3的剖面视图。如图中所示，盖3的顶部内形成了两个孔7a，7b，它们与双管座9的上管10a，10b相配合，从而当盖3接合到双管座9上时，上管10a，10b的管口11a，11b被孔7a，7b充分覆盖。并且，在孔7a，7b的内部还形成了凸台8a，8b，这两个凸台8a，8b进一步封闭上管10a，10b的管口11a，11b，当盖3与双管座9接合时，这有效地防止了牙科材料从管口11a，11b溢出。
图6和图7分别示出了双管座9的侧视图和仰视图。从图6中可以清楚地看到，在双管座9的两侧形成了弹性卡扣装置14a，14b，它们可通过在弹性卡扣装置的顶部按压而张开，并通过弹性卡扣装置材料自身的弹性而恢复原状，从而便于通过弹性卡扣装置14a，14b底部的凸缘18a，18b(见图9)与双管注射器2顶部形成的凸缘24(见图9)接合或脱离接合，进而将双管座9(以及盖3)连接在双管注射器2上(后文将进一步详述)。在图6中还会进一步注意到，凸棱16形成了双管座9与双管注射器2之间的防错插接设计。这一点结合图7所示将更加明显。
图7示出的是双管座9的仰视图，此视图明确图示了双管座9底部用于与双管注射器2进行接合的接合特征。如图中所示，双管座9仅在图中的右侧形成了凸棱16，而另一侧并不形成凸棱。因而对应地，在双管注射器2的顶部，仅在对应的一侧形成与凸棱16接合的凹槽。这构成了双管座9与双管注射器2之间的防错插接设计。凸棱16以及对应的凹槽的位置根据双管注射器的型号不同而可能发生改变。此外，在图7中，还会观察到，双管座9的底部左右两侧形成了相对的开口，但是开口的角度不同，左侧较窄而右侧较宽。以上开口设计用于与双管注射器2顶部的对应的凸台形成接合。由于存在开口角度差异，如果操作人员弄错了双管座9与双管注射器2的接合方向，则它们将无法接合，这进一步防止了双管座9与双管注射器2之间的错误连接，进而避免了牙科材料的交叉污染。该图示的情形仅仅是示例性的，根据实际的需要，本领域技术人员当然还可以设想不同的开口特征来满足防错连接的需要。例如，设计不同形状的开口，或者改变开口的位置等。
为了更好地理解盖3、双管座9以及双管注射器2的接合关系，进一步参考图8和图9，它们以不同方向的两个剖面图示出了三者接合时的状态。在图8中，将会看到，双管座9的下管12a，12b与双管注射器2的管口22a，22b形成插接，双管座9的上管又进一步与盖3中对应的孔口形成连通通道，并且此连通通道在盖3的顶部被凸台所封闭。在双管座9的上管与下管之间沿轴线存在一定的偏移量，从而形成如图中所示向外张开的两个通道。此设计的原因在于，双管注射器的两个出口之间通常距离较近，容易造成管口处材料的交叉污染。通过此张开的通道设计，避免了双管注射器的两个管口靠近而造成的交叉污染。观察图9，还会看到，弹性卡扣装置14a，14b底部的凸缘18a，18b与双管注射器2顶部的凸缘24形成了接合，从而实现了可靠而方便的连接。
由此，当盖3接合在双管座9上时，能够有效地防止双管注射器2内的材料与外界接触，并且当盖3从双管座9上取下时，能够方便地将双管注射器2内的材料挤出进行混合。并且，双管座9也能够以方便快捷的方式与双管注射器2接合或脱离接合。根据本发明的可更换式手动混合连接器结构简单，拆接快速方便，并且能够有效防止错误操作，进而防止两种材料发生交叉污染。并且，由于不需要预设混合空间，避免了材料残留在混合空间内造成的材料浪费。这对于牙医的现场操作具有充分的便利性和实用性。
以上利用示例来公开包括最佳模式的本发明，并且也使得所属领域技术人员能够实施本发明，所述实施包括制作和利用任何装置或系统。本发明的可授予专利权的范围由权利要求限定，并且可包括所属领域技术人员所能够想到的其它示例。如果这种其它示例具有并非不同于权利要求的文字语言的结构元件，或者如果这种其它示例包括与权利要求的文字语 言具有非实质性差异的等效结构元件，则这种其它示例意在处于权利要求的范围内。
