摘要： A method includes receiving, by a processor of a dialysis machine, a dialysate flow rate, a bicarbonate setting value, a signal from a pressure sensor configured to measure a pressure within a container, and a signal indicating a state of a fill valve; determining, based on the signal received from the pressure sensor and the state of the fill valve, fill parameters; determining a volume of the container based on at least two of the fill parameters; determining a depletion time in which the concentrate will be depleted from the container based on the volume of the container, the dialysate flow rate, and the bicarbonate setting value; determining, based on the depletion time, an amount of time remaining before the concentrate will be depleted from the container; and causing the dialysis machine to indicate the amount of time remaining before the concentrate will be depleted from the container.

摘要： A measurement apparatus for a peritoneal dialysis apparatus (10) comprises a connecting means (102), which is in contact with a drain line system (104) of the peritoneal dialysis apparatus (10), and electrochemical sensor means (110). The measurement apparatus (100) receives spent dialysate through the drain line system (104) when the dialysis apparatus (10) is connected with a patient (12). The electrochemical sensor means (110), which is in contact with the spent dialysate, outputs an electric signal in response to contents of urea and glucose of the spent dialysate for data processing and/or data presentation of the electric signal.

摘要： A monitoring device operates on a pressure signal from a blood processing apparatus which has an extracorporeal blood circuit for pumping blood through a dialyzer, and a treatment fluid supply system for pumping a treatment fluid through the dialyzer. The monitoring device has a first input block for obtaining a first pressure signal, and a second input block for obtaining a second pressure signal. An emulation block generates, as a function of the second pressure signal, an emulated first pressure signal which emulates a concurrent signal response of the first pressure sensor, and a filtering block generates a filtered signal as a function of the first pressure signal and the emulated first pressure signal, so as to suppress, in the filtered signal compared to the first pressure signal, signal interferences originating from the treatment fluid supply system. A pulse detection block processes the filtered signal for detection of subject pulses.
