Abstract

一种具有模制的流动通道的盒，通道容纳在被粘接或机械连接到刚性基底的弹性板上。手术操作台包括盒接纳区域，该区域具有带滚轮的泵压头，滚轮从泵电动机的旋转轴线径向安装，并将弹性的流动通道压靠在刚性基底上。盒通过闭锁机构被抵靠泵压头保持在适合的位置，闭锁机构牵拉盒抵靠泵压头。弹性板的外周包括突起的脊部或凸台，它们在弹性板的(多个)区域处或附近整体形成为弹性板的一部分，弹性板受到高的瞬态或者静态压力的作用。脊部允许弹性板被牢固地压靠在手术操作台的盒接纳部分上，然而仍允许盒被牵拉抵靠泵压头。脊部抵靠手术操作台的盒接纳区域的牢固接合有助于确保当盒暴露到高的瞬态压力时弹性板不会移动。

Description

具有弹性夹持肋的盒
技术领域
本发明总体涉及蠕动泵，并且更具体的是涉及在眼科手术设备中使用的流体盒(cassette)。
背景技术
大部分现有技术的蠕动泵利用旋转的滚轮头(roller head)通过压缩或者挤压一定长度的挠性管(有时在一固定的轨道之间)而工作。当滚轮头旋转时，滚轮夹紧所述管的一部分，并且将收集在滚轮之间的所述管中的任何流体沿着旋转方向推动。由于蠕动泵的可预见的、恒定的流动特性，它们广泛用在医疗场所中。然而，这些现有技术的系统通常需要将泵的所述管部分手动连接到旋转的滚轮头周围。
现有技术的利用旋转滚轮头的蠕动泵通常还产生不适合的压力脉动。数个脉动衰减装置已经开发出以解决这个问题(例如见美国专利No.4,921,477(Davis))。
另一种现有技术的泵在美国专利No.6,293,926 B1(Sorensen等)中公开，其描述了这样一种蠕动泵，该蠕动泵具有容纳在弹性板上的模制的流动通道，所述弹性板粘接或者机械连接到刚性基底上。泵的端部滚轮从泵的电机的旋转轴线径向安装，并且挤压弹性流动通道抵靠刚性基底。本专利所述发明的商业体现是Alcon Laboratories，Inc.，Fort Worth，Texas(得克萨斯州Forth Worth的爱尔康公司)销售的INFINITIVision System(视觉系统)。这个手术操作台使用流体控制系统或者盒，其中弹性板被摩擦配合在刚性基底中，没有使用任何粘结剂。这种构造方法已经证明是非常可靠的，但是这种市场上销售的系统主要用于白内障手术，并且除了蠕动泵以外没有其它的真空源。因此，流体系统主要暴露在负压或者真空下，并且没有暴露给瞬态的高的正压，例如在回流操作过程中，在眼后段手术过程中使用文丘里泵作为主要真空源时所遇到的。这些高的正压可以高至70毫米汞柱，并且如果使用了摩擦配合的构造技术，那么在弹性体/基底的交界面处可能会产生失效。
因此，需要这样一种手术盒，其能够降低在瞬态的正压作用下盒的失效的可能性。
发明内容
本发明通过提供这样一种盒而对现有技术的盒进行了改进，所述盒具有容纳在弹性板上的模制的流动通道，所述弹性板粘接或者机械连接到刚性基底。手术操作台包括盒接纳区域，该区域具有带有滚轮的泵压头，所述滚轮从泵的电动机的旋转轴线径向安装，并且将所述弹性的流动通道压靠在刚性基底上。所述盒通过闭锁机构被抵靠泵压头保持在适合的位置，所述闭锁机构牵拉所述盒抵靠泵压头。弹性板包括突起的脊部或者凸台，所述脊部或者凸台在弹性板的(多个)区域处或者其附近整体形成为弹性板的一部分，所述弹性板受到高的瞬态或者静态压力的作用。所述脊部允许弹性板被牢固地压靠在手术操作台的盒接纳部分上，然而仍然允许盒被牵拉抵靠泵压头。所述板的脊部抵靠手术操作台的盒接纳部分的牢固接合有助于确保当盒暴露在高的瞬态压力下时所述弹性板不会移动。
本发明的一个目的是提供一种使用模制的弹性流动通道的蠕动泵。
本发明的另一个目的是提供一种具有径向定向的泵滚轮的蠕动泵。
本发明的又一个目的是提供一种具有泵滚轮的蠕动泵，所述泵滚轮将弹性流动通道压靠在刚性基底上。
本发明的又一个目的是提供一种具有弹性板的盒，所述板配合到刚性基底上。
本发明的再一个目的是提供一种具有弹性板的盒，所述板配合到刚性基底上，从而当盒暴露在高的瞬态压力下时弹性板不会移动。
根据下面详细的说明、附图和权利要求，本发明的这些和其它优点和目的将变得显而易见。
附图说明
图1是本发明的盒的正面透视图。
图2是本发明的盒的后部透视图。
图3是本发明的手术盒安装在手术操作台中的示意图。
图4是用在本发明的盒上的泵的弹性板的后部透视图。
具体实施方式
如图1-3清楚所示，本发明的盒10大体包括主体11，主体11具有前表面12，前表面12包括多个流体连接件14，用于将盒10流体连接到在手术过程中使用的输注流体源20和手术手持件22。盒10还可包括手柄16，用于辅助将盒10安装到手术操作台24并且从操作台24拆除。如图2清楚所示，盒10具有后表面18，后表面18与前表面12相对，并且适用于与手术操作台24进行机械的和流体的相互作用。多个弹性的在交界面处形成的板通过摩擦安装在盒10的后表面18上，例如气动(pneumatics)弹性体25、输注弹性体26、抽吸弹性体28、阀弹性体100和泵弹性体30。盒10安装在操作台24内，从而泵弹性体30通过闭锁件38被压靠在泵机构32上，泵机构32安装在操作台24内。盒10可以利用任何适合的材料模制，例如热塑塑料，并且弹性体25、26、28和30可以利用任何适合的弹性体模制，例如硅橡胶。
如图4清楚所示，泵弹性体30基本是圆形的，其尺寸和形状与安装到泵机构32的滚轮头(未示出)类似。泵弹性体30包括泵送通道34，通道34与泵机构32相互作用以提供穿过盒10的蠕动的泵送作用。盒10和泵机构32的操作在美国专利No.6,293,926 B1(Sorensen等)中有详细的描述，该专利在此引为参考。为了确保泵弹性体25、26、28、30和100被牢固地压靠在操作台24上，从而当暴露到高的瞬态压力时有助于减小弹性体25、26、28、30和100从盒10移动的可能性，弹性体25、26、28和30包括突起的肋或者凸台36，所述肋或者凸台36围绕受到高的瞬态或者静态压力的弹性体25、26、28、30和100的整个区域延伸。当闭锁件38将盒10挤压在操作台24中时，肋36被挤压，从而有助于防止弹性体25、26、28、30和100的任何移动。
这里的说明是为了描述和解释的目的而给出的。对于本领域的普通技术人员来说，在不脱离此处所述的本发明的范围或精神的情况下，对本发明做出各种修改是显而易见的。
