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.

12. An infusion pump method comprising:
-
depressing a pain controlled analgesic input device; sending an electrical signal in response to the depressed pain controlled analgesic input device; electronically sensing the sent electrical signal; electronically determining whether the sensed electrical signal is discontinuous; and if the sensed electrical signal is determined to be discontinuous, electronically sending an output indicative of the pain controlled analgesic input device functioning improperly. - View Dependent Claims (13, 14)
