DIALYSIS MONITORS, METHODS RELATING TO HEATING OF FLUIDS, AND USE OF BATTERY UNITS OF DIALYSIS MONITORS

摘要

A dialysis monitor with a treatment fluid path configured to provide treatment fluid to a dialyzer when dialysis treatment is performed by the dialysis monitor is provided. A battery unit is connected to a controller and at least a portion of the functional elements of the dialysis monitor in order to provide back-up power should the supply of external power be discontinued. Energy of the battery unit is used to provide energy to the heater in preparation for and/or at least partly during thermal disinfection of the treatment fluid path or when starting up the preparation of treatment fluid thereby shortening the time required for the thermal disinfection and the starting up of the preparation of treatment fluid, respectively.

主权项

1. A dialysis monitor for performing dialysis treatment on a patient, said dialysis monitor comprising:
a treatment fluid path configured to provide treatment fluid to a dialyzer when dialysis treatment is performed by the dialysis monitor; a heater configured to heat fluid present in the treatment fluid path; a battery unit configured to provide back-up power to at least a portion of the dialysis monitor should a supply of external power be discontinued; a first switch connected between the battery unit and the heater, said first switch having a first state where energy is supplied from the battery unit to the heater and a second state where energy is substantially prevented from being supplied from the battery unit to the heater; and a controller programmed to control a state of said first switch and to set the state of said first switch to said first state, thereby supplying energy from the battery unit to the heater, at a time when dialysis treatment is not being performed on the patient by the dialysis monitor.
