Abstract: A power management system for a medical device while operating on battery power comprises a control circuitry, wherein the medical device has a plurality of functions. The control circuitry is configured to measure a state of charge remaining in a battery powering the medical device, to associate each of the plurality of functions with one of a plurality of operable states, and to correlate each operable state with a battery charge level. The control circuitry is further configured to select one of the plurality of operable states according to the state of charge remaining in the battery and to implement at least one function associated with the selected operable state.

IPC: A61M1/14
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 predetermined 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. The cycler may also be configured to have a heater control system that monitors both the temperature of a heating tray and the temperature of a bag of dialysis fluid in order to bring the temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.

Abstract: A system for adjusting a negative pressure used to withdraw fluid from the peritoneal cavity of a dialysis patient is disclosed. The system comprises a controller arranged to control a pump by providing negative pressure in a magnitude that oscillates within a pre-determined range of negative pressures as a function of a measured flow rate of fluid.

Abstract: A heating system for a peritoneal dialysis apparatus comprising: a heater bag containing dialysate solution and positioned on a heater pan; a pumping apparatus configured to pump dialysate into and out of the heater bag; an electrical heating element to heat the heater pan; one or more heater pan temperature sensors to detect a temperature of the heater pan; a dialysate temperature sensor mounted in the heater pan, thermally isolated from the heater pan, and configured to contact an outer surface of the heater bag; and a controller programmed to perform an inner control loop process that modulates electrical power provided to the heating element to achieve a target heater pan temperature as measured by the one or more heater pan temperature sensors, and programmed to perform an outer control loop process that determines the target heater pan temperature based on a difference between a pre-determined target dialysate temperature and the dialysate temperature as measured by the dialysate temperature sensor.
