Misloaded IV tube detector for an IV pump
First Claim
1. A peristaltic pump comprising:
- a supporting structure including a base;
a resilient tube;
a peristaltic pumping member carried by the supporting structure, said tube being positionable on the base in a proper position in which the peristaltic , pumping member can properly progressively squeeze the tube to pump a fluid through the tube and in an improper position;
a door;
means for mounting the door on the supporting structure for movement between an open position in which the door allows access to the base and a closed position in which the door impedes access to the base; and
means responsive to the tube being in said improper position for positively preventing movement of the door to said closed position.

Abstract
A peristaltic pump comprising a housing (19), including a base (21), a resilient tube (27) and a peristaltic pumping fingers (31) carried by the supporting structure. The tube (27) is positionable on the base (21) in a proper position and an improper position. In the proper position, the peristaltic pumping fingers (31) can properly progressively squeeze the tube to pump a fluid through the tube and in an improper position. A door (23) is mounted on the housing (19) for movement between an open position and a closed position. A latch (25) includes a pivotable latch member (51) on the door (23) and a fixed latch member (55) on the housing (19). The pivotable latch member (51) is movable between a latching position in which the door (23) is locked in the closed position and a releasing position in which the door (23) is not locked in the closed position. If the tube (27) is in the improper position, the pivotable latch member (51) is prevented from being placed in the latching position.

4. A peristaltic pump comprising:
-
a supporting structure including a base; a resilient tube; a peristaltic pumping member carried by the supporting structure, said tube being positionable on the base in a proper position in which the peristaltic pumping member can properly progressively squeeze the tube to pump a fluid through the tube and in an improper position; a door; means for mounting the door on the supporting structure for movement between an open position in which the door allows access to the base and a closed position in which the door impedes access to the base; a latch including a first latch member member on the door and a second latch member on the supporting structure, said latch members being relatively movable between a latching position in which the door is locked in the closed position and a releasing position in which the door is not locked in the closed position; and means responsive to the tube being in said improper position for preventing the latch members from being in said latching position. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
