  • Publication number: 20230390472
    Abstract: 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.

  • Publication number: 20210290844
    Abstract: 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.

  • Publication number: 20210228793
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the 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 to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period.
