摘要： Embodiments to the present invention provide a peristaltic pump. This peristaltic pump includes a flexible flow path, an exterior casing, an elastomeric member, and a number of rollers driven by a motor. The exterior casing and elastomeric member have a first and second annular recess, respectively. An annular flow path guide is formed when the exterior casing and elastomeric member are mechanically coupled. Rollers move along the annular flow path to compress and release the flexible flow path and in so doing draw fluid through the flexible flow patch to achieve pumping action. Mechanical guides proximate to the first annular recess and second annular recess prevent relative motion between the first annular recess and second annular recess ensuring that the flexible flow path remains in place.
摘要翻译：本发明的实施例提供一种蠕动泵。该蠕动泵包括柔性流动路径，外部壳体，弹性体构件以及由马达驱动的多个滚子。外壳和弹性构件分别具有第一和第二环形凹部。当外壳和弹性体构件机械联接时，形成环形流路引导件。辊沿着环形流动路径移动以压缩和释放柔性流动路径，并且如此地通过柔性流动补片抽吸流体以实现泵送动作。靠近第一环形凹部和第二环形凹槽的机械导轨防止第一环形凹部和第二环形凹部之间的相对运动，确保柔性流动路径保持在适当位置。

摘要： Embodiments of the present invention provide a surgical cassette with compliant clamping zones to provide more uniform loading. According to one embodiment of the present invention, a surgical cassette includes a clamping portion that is configured to deform to conform to non-uniform load profile applied to the cassette. The clamping portion can include ribs that are sized and made of a suitable material such that the ribs will deflect predictably in the elastic region and flow plastically when the material yield point is exceeded. The use of ribs creates discrete small load areas that will deflect and distort predictably and non-catastrophically at high loads. This allows for the absorption of accumulated tolerances between the clamping mechanism and cassette (e.g., the non-parallelism between the clamping mechanism and cassette) while still providing a distributed load on the cassette.
摘要翻译：本发明的实施例提供具有顺应夹持区域的外科手术盒以提供更均匀的载荷。根据本发明的一个实施例，手术盒包括夹持部分，该夹紧部分被构造成变形以符合施加到盒的不均匀载荷分布。夹紧部分可以包括尺寸并由合适材料制成的肋，使得肋将在弹性区域中可预测地偏转并且当超过材料屈服点时塑性流动。肋骨的使用会产生离散的小负荷区域，这些区域会在高负荷下预测和非灾难性地偏转和变形。这允许在夹持机构和盒之间吸收积累的公差（例如，夹紧机构和盒之间的非平行度），同时仍然在盒上提供分布式负载。
