Abstract:
For use in a flow control console of the type having a recessed receiving portal including a reference wall in a first plane against which the distal face of a multi conduit cassette is to be received, to engage a peristaltic pump rotatable in a second plane parallel to the first at one side of the reference wall, and to be engageable by control elements adjacent one edge of the reference wall, and spaced apart from the peristaltic pump, a cassette system comprising:an adapter element engageable to the reference wall and spanning from adjacent the peristaltic pump to adjacent the control elements when installed, the adapter element including a distal wall portion proximate to the reference wall when installed and a proximally extending shoulder asymmetrically disposed relative to the peristaltic pump and including a pump loop receiving element at an approximately tangential position relative to the peristaltic pump; anda cassette element including interior flexible tubing and configured to engage the adapter element adjacent the distal wall and shoulder therein, the cassette element including a side wall having flexible tubing therein accessible to the control elements in the console, and further including a pump loop extending toward the peristaltic pump at one side of the adapter element and including a coupling element seating in the receiving element and forming a pump loop for wrapping about the peristaltic pump.
