A system for pairing a controller and an infusion pump is disclosed. The system includes an infusion pump, a controller device and a user interface residing on both the infusion pump and the controller. The user interface includes a pairing mode for enabling wireless communication between the infusion pump and the controller device, wherein the user interface requires both the infusion pump and the controller to be in the pairing mode simultaneously. Also, a method of changing a power source in an infusion pump is disclosed. The method includes placing the infusion pump in idle mode wherein the infusion pump stops delivery. Removing the first power source from the infusion pump. Replacing the first power source with a second power source in the infusion pump, and maintaining the insulin on board during the changing of the first power source with the second power source.

Methods and systems for controlling an infusion pump

Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of the diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber. Improved heater control circuitry is also disclosed, to provide added or redundant safety measures, or to reduce current leakage from a heater element during pulse width modulation control of the heater element. Improvements are also disclosed in an application of negative pressure during a drain phase in peritoneal dialysis therapy, and to control an amount of intraperitoneal fluid accumulation during the therapy. Improvements in efficiency are also disclosed in movement of fluid into and out of a two-pump cassette and a heater bag of the peritoneal dialysis cycler, and in synchronization of operation of two or more pumps in the peritoneal dialysis cycler or other fluid handling devices using a multi-pump arrangement.

Medical treatment system and methods using a plurality of fluid lines

A medical treatment system, such as a peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, the peritoneal dialysis system may include a control system that can adjust a volume of fluid infused into a peritoneal cavity to prevent intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle of the one or more therapy cycles to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting a next therapy cycle of the one or more therapy cycles. The control system may also adjust a dwell time of the fluid within the peritoneal cavity during the one or more therapy cycles in order to complete a therapy within a scheduled time period. A cycler may also be configured to have a heater control system that monitors both a temperature of a heating tray and a temperature of a bag of dialysis fluid in order to bring a temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.

An infusion pump assembly includes a reservoir assembly configured to contain an infusible fluid. A motor assembly is configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly. Processing logic is configured to control the motor assembly. The processing logic includes a primary microprocessor configured to execute one or more primary applications written in a first computer language; and a safety microprocessor configured to execute one or more safety applications written in a second computer language.

Multi-language/multi-processor infusion pump assembly

A medical remote controller device is disclosed. The device includes a display and at least one input switch dedicated to bolus delivery wherein a bolus delivery is programmed when the input switch receives an input and wherein the number of inputs received by the input switch determines the amount of bolus to be delivered.

Infusion pump methods and systems

An infusion pump system is disclosed. The system includes at least one infusion pump, a companion device, the companion device in wireless communication with the infusion pump, and a user interface on the companion device, the user interface adapted to receive textual input.

A method for delivering a target volume of fluid to a destination is provided. The method includes delivering a first volume of fluid to the destination in increments each having approximately a first incremental volume, the first volume of fluid being less than the target volume and delivering a second volume of fluid to the destination in increments each having approximately a second incremental volume, the second incremental volume being less than the first incremental volume, such that the sum of the first volume and the second volume is approximately equal to the target volume.
