Fail-safe drug infusion therapy system
First Claim
1. An infusion pump system comprising:
- a user interface device comprising a display and a first hardware processor; and
a pump device comprising a motor and a second hardware processor;
wherein the first hardware processor is configured to;
transmit infusion parameters to the pump device over a communication link, wherein the second hardware processor is configured to control the motor for delivery of infusion fluid based on the infusion parameters;
detect a first status of the pump device;
determine that the pump device is in an inoperative state based on the detected first status;
command the pump device to reboot; and
update the pump device after it is rebooted,wherein the second hardware processor is configured to determine a time that the second hardware processor is able to operate independently of the first processor and display the time on the display of the user interface device.

Abstract
A fail-safe drug infusion system, including a user interface controller (UIC) and at least one pump motor controller (PMC), with protocols that enable the PMC to operate therapy delivery for a limited amount of time if the UIC fails or the communication link between the UIC and the PMC is interrupted. Includes synchronization methods to synchronize the delivery information back to the UIC after the UIC reboots or after the communication link is restored. The PMC may apply intelligent fail-safe drug infusion therapy by temporarily displaying therapy information, for example information normally displayed by the UIC, while taking control of alarm signaling and providing minimal user control of the therapy until the UIC restores itself, the infusion completes normally, or the user stops the infusion. If the PMC becomes inoperable, the UIC may wait for the PMC to reboot, or attempt to switch infusion channels to provide robust drug infusion.

7. An infusion pump system comprising:
-
a pump device comprising a motor and a first hardware processor, wherein the pump device is configured to receive infusion parameters from a user interface device; wherein the first hardware processor is configured to; determine that the user interface device is in an inoperative state at a first time; command the user interface device to reboot; continue pumping infusion fluid using stored infusion parameters; determine that that user interface device is in an operative state at a second time after the first time; and transmit therapy data acquired between the first time and the second time to the user interface device. - View Dependent Claims (8, 9, 10, 11)

12. An infusion pump method for managing a pump device comprising a motor and a first hardware processor, wherein the pump device is configured to receive infusion parameters from a user interface device, the infusion pump method comprising:
-
determining, by the first hardware processor, that the user interface device is in an inoperative state at a first time; commanding, by the first hardware processor, the user interface device to reboot; continuing, by the first hardware processor, pumping infusion fluid using stored infusion parameters; determining, by the first hardware processor, that user interface devices is in an operative state at a second time after the first time; and transmitting, by the first hardware processor, therapy data acquired between the first time and the second time to the user interface device. - View Dependent Claims (13, 14, 15, 16)
