Claim:
A medical pump for use with a cassette, comprising: a main chassis having a fixed seat thereon; a main carriage connected to the main chassis and having an opening therein adapted to receive a cassette, the opening forming a footing which restricts movement of the cassette within the main carriage; wherein when the cassette is restricted against movement within the main carriage, together the main carriage and the cassette are able to be driven inwardly with respect to the main chassis along a linear path from an open position wherein the main carriage is spaced from the fixed seat to a closed position to engage the cassette to the fixed seat; and a position sensor being operatively associated with the main carriage for tracking the position of the main carriage from the open position to the closed position; wherein the fixed seat establishes the vertical and lateral position of the cassette, and the fixed seat and main carriage dictate the inward position of the cassette by pressing the cassette and the fixed seat against a common surface of the main carriage.
