1. An infusion pump method comprising:
- enabling a pain controlled analgesic input device associated with an infusion pump to be depressed;
sensing the depressed pain controlled analgesic input device;
determining an amount of time that the depressed pain controlled analgesic input device has been sensed; and
if the determined amount of time is greater than a predetermined value, providing an output indicative of the pain controlled analgesic input device being stuck.

Abstract
An infusion pump includes: a housing, a pump actuator supported by the housing, electronics configured to control the pump actuator, a pain controlled analgesic (“PCA”) input device, a cord having a remote end connected to the PCA input device and a local end connected to the housing, a remote integrated circuit; and a local integrated circuit in communication with the electronics and the remote integrated circuit so as to provide operational information concerning the PCA input device to the electronics.

5. An infusion pump comprising:
-
a housing; a pump actuator supported by the housing; electronics configured to control the pump actuator; a pain controlled analgesic input device; a memory; a controller in operable communication with the pain controlled analgesic input device; and an algorithm stored in the memory, which when executed by the controller, causes the controller to (i) sense a depression of the pain controlled analgesic input device, (ii) determine an amount of time that the depressed pain controlled analgesic input device has been sensed, and (iii) if the determined amount of time is greater than a predetermined value, provide an output indicative of the pain controlled analgesic input device being stuck. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. An infusion pump comprising:
-
a housing; a pump actuator supported by the housing; a pain controlled analgesic input device configured to activate the pump actuator; and a controller including an interface configured to receive a signal indicating a depression of the pain controlled analgesic input device, and a timer configured to determine an amount of time that the pain controlled analgesic input device has been depressed, wherein the controller is configured to provide an output indicative of the pain controlled analgesic input device being stuck if the determined amount of time is greater than a predetermined value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
