INFUSION PUMP INCLUDING PAIN CONTROLLED ANALGESIC ("PCA") APPARATUS
First Claim
Patent Images
1. An infusion pump method comprising:
- providing a pain controlled analgesic device having a remote controller;
operably coupling an infusion pump actuator to a local controller;
attempting to send an electrical signal from one of the local controller and the remote controller to the other of the local controller and the remote controller;
attempting to receive the sent electrical signal at the other of the local controller and the remote controller; and
if the other of the local controller and remote controller does not receive the sent electrical signal, sending an output that is indicative of a frayed cord or an open circuit condition between the remote controller and the local controller.

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.

9. 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 a value greater than a predetermined value, providing an output indicative of the pain controlled analgesic input device being stuck. - View Dependent Claims (10, 11, 12)

13. An infusion pump method comprising:
-
maintaining a depression of a pain controlled analgesic input device; sending an electrical signal in response to the maintained depression of the pain controlled analgesic input device; sensing the sent electrical signal; and determining whether the sensed electrical signal is discontinuous; and if the sensed electrical signal is determined to be discontinuous, sending an output indicative of the pain controlled analgesic input device functioning improperly. - View Dependent Claims (14, 15)

16. An infusion pump method comprising:
-
receiving an electrical signal at a local controller that is assumed to be a bolus request signal; in response to the received electrical signal, sending from the local controller to a remote controller a confirm bolus request electrical signal to verify that the received electrical signal is a bolus request signal; waiting for the remote controller to respond to the confirm bolus request electrical signal; and if the remote controller does not respond to the confirm bolus request electrical signal, sending an output that is indicative of a short circuit condition between the remote controller and the local controller. - View Dependent Claims (17, 18, 19, 20)
