| 20080240951 | SYSTEM AND METHOD OPERABLE TO PREVENT TUBING DISPLACEMENT WITHIN A PERISTATLTIC PUMP - 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. | 10-02-2008 |

| 20090105657 | Connector to cassette interface system - The disclosed connector to cassette interface system includes a set of individual keyed connectors having a shroud on the lower portion. The perimeter of each shroud includes an array of tabs or protrusions keyed to one of a corresponding array of skirted portals in the cassette cover. The tabs or protrusions on the shroud portion of each individual keyed connector may further serve to prevent rotation of each connector beyond about 60°. | 04-23-2009 |
