Abstract
Disclosed in some embodiments is an electronic intravenous infusion pump provided with a disposable, insertable pump cartridge that is connectable to one or more intravenous fluid infusion sources, wherein the pump is coupled to a first fluid reservoir and a second fluid reservoir, wherein fluid is selectively drawn from the first fluid reservoir and the second fluid reservoir to provide substantially continuous infusion of substantially the same medical fluid to a patient.
Claims22
A control system for controlling operation of an infusion pump of an infusion pump system, the infusion pump system comprising a first fluid reservoir and a first supply line, a second fluid reservoir and a second supply line, a common channel in selective fluidic communication with the first supply line and the second supply line, and an infusion pump, wherein the infusion pump is operable to drive liquid through the common channel to a patient, the control system comprising:
- one or more hardware processors;
- and
- a memory storing executable instructions that when executed by the one or more hardware processors, configure the infusion pump to:
- draw liquid from the first fluid reservoir and first supply line;
- automatically discontinue drawing liquid from the first fluid reservoir and first supply line and begin drawing fluid from the second fluid reservoir and second supply line upon receiving an indication that the first fluid reservoir is in a depletion zone and
- automatically discontinue drawing fluid from the second fluid reservoir and second supply line and begin drawing fluid from the first fluid reservoir and first fluid line upon receiving an indication that the second fluid reservoir is in the depletion zone,
- wherein the control system is configured to deliver to the patient substantially continuously fluid drawn including during transitions between the first fluid reservoir and the second fluid reservoir.
A method for controlling operation of an infusion pump of an infusion pump system, the infusion pump system comprising a first fluid reservoir, a second fluid reservoir, a common channel in selective fluidic communication with the first fluid reservoir and the second fluid reservoir, and an infusion pump, wherein the infusion pump is operable to drive fluid through the common channel, the method comprising:
- drawing fluid from the first fluid reservoir through the common channel;
- automatically discontinuing drawing fluid from the first fluid reservoir and drawing fluid from the second fluid reservoir through the common channel upon receiving an indication the first fluid reservoir is depleted;
- and
- automatically discontinuing drawing fluid from the second fluid reservoir and drawing fluid from the first fluid reservoir through the common channel upon receiving an indication that the second fluid reservoir is depleted,
- wherein fluid drawn from the first fluid reservoir through the common channel is substantially successively continuous with fluid drawn from the second fluid reservoir through the common channel.

- one or more hardware processors;
- and
- a memory storing executable instructions that when executed by the one or more hardware processors, configure the infusion pump to:
- draw fluid from the first fluid reservoir through the common channel;
- automatically discontinue drawing fluid from the first fluid reservoir and draw fluid from the second fluid reservoir through the common channel upon receiving an indication that the first fluid reservoir is depleted;
- and
- automatically discontinue drawing fluid from the second fluid reservoir and draw fluid from the first fluid reservoir through the common channel upon receiving instructions to draw fluid from the first fluid reservoir,
- wherein fluid drawn from the first fluid reservoir through the common channel is substantially successively continuous with fluid drawn from the second fluid reservoir through the common channel.
