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 connected to the main chassis and 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 inwardly with respect to the main chassis 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
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.

13. A medical pump for use with a cassette having a pumping chamber, 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 carriage footing which restricts movement of the cassette within the main carriage, the main carriage being movable with respect to the chassis and the fixed seat from an open position wherein the main carriage and cassette are free from contact with the fixed seat to a closed position to engage the cassette to the fixed seat; and wherein the main carriage floats with respect to the main chassis allowing the fixed seat to dictate the position of both the main carriage and cassette when the main carriage is in the closed position. - View Dependent Claims (14, 15, 16, 17, 18)
