Fluid delivery device identification and loading system
View Patent ↗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.
1. A medical pump for use with a cassette, comprising:
a main chassis having a fixed seat thereon;
a main carriage slidably 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, the main carriage being automatically movable linearly 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
a rear carriage assembly connected to the main carriage, the rear carriage assembly including a manual release element operatively associated with the main carriage so that once the manual release element is actuated by a user the main carriage is moved to the open position.
2. The medical pump of claim 1 , further including an actuator connected to the main carriage to automatically move the main carriage, wherein the actuator is connected to the main carriage by the rear carriage assembly, once the manual release element is actuated by a user the rear carriage assembly disengages the actuator from the main carriage.
3. The medical pump of claim 2 , wherein the actuator cannot be reengaged to the main carriage by manually moving the main carriage horizontally inwardly with respect to the main chassis.
4. The medical pump of claim 1 , wherein the manual release element is located remotely from the main carriage.
