Fluid delivery device identification and loading system
First Claim
1. A medical pump for use with a cassette, comprising:
- a main chassis having a fixed seat thereon;
a main carriage having an opening therein adapted to receive a cassette, the opening forming a carriage footing which restricts movement of the cassette within the main carriage, the main carriage being movable from an open position horizontally inwardly with respect to the main chassis to a closed position to engage the cassette to the fixed seat; and
an actuator connected to the main carriage to automatically move the main carriage from the open position to the closed position.

Abstract
A medical pump includes a chassis having a fixed seat, and a main carriage having a carriage footing for receiving a fluid delivery device and restricting its movement. An actuator automatically moves the main carriage between open and closed positions to engage the fluid delivery device to the seat. The seat establishes the position of both the main carriage and fluid delivery device in the closed position. The actuator is connected to the main carriage by a rear carriage assembly having a manual release element for disengaging the actuator from rear carriage assembly and thereby from the main carriage. A processing unit detects jam conditions by processing carriage position data and electrical load data from the actuator.
