1. A cassette mountable to a pumping mechanism for positioning a tube adjacent to a plurality of tube engaging members of a pumping mechanism, the cassette comprising:
- a tubing support surface having a pump anchor at one end and two hooks at an opposite end;
a housing having a bottom face, a front face, a back face and two side faces, wherein the housing is permanently affixed to the tubing support surface and is sized for housing a fluid reservoir, wherein the tubing support surface defines a top of the cassette, the front, back, and side faces are adjacent to the tubing support surface, and the bottom face defines a bottom of the cassette, wherein one of the side faces is adjacent to the one end of the tubing support surface, and the other side face is adjacent to the opposite end of the tubing support surface; and
a hinge to reversibly rotate one rotatable face of the housing relative to the remainder of the housing, wherein rotation of the one rotatable face of the housing provides access to an interior of the housing, the hinge defining an axis of rotation extending generally transverse to the one rotatable face.

9. A method for using a cassette having a tubing support surface mountable to a pumping mechanism, the method comprising the steps of:
-
providing a cassette having a bottom, a front face, a back face, at least two side faces, a hinge and a tubing support surface for positioning a tube adjacent to a pumping mechanism, the hinge extending generally parallel to the tubing support surface; rotating one of the faces of the housing relative to the remainder of the housing around the hinge to access the interior of the housing; positioning a fluid reservoir and a tube within the interior of the housing; extending the tube along the tubing support surface of the housing; closing the housing by rotating the rotatable face of the housing; and mounting the cassette to the pumping mechanism. - View Dependent Claims (10)
