Abstract
A dialysis system includes: an enclosure; a dialysate pump carried by the enclosure and arranged to pump dialysate to a patient or dialyzer; at least one container connected fluidly to the dialysate pump; a load cell positioned to weigh dialysate located within the container; an accelerometer positioned and arranged to detect a force imparted on at least one of the enclosure and the container; and electronics configured to receive a first signal from the load cell and a second signal from the accelerometer and process the first and second signals so as to determine if an abnormality sensed by the load cell is a system error or a mechanical interference.
Claims24
A dialysis system comprising:
- an enclosure;
- a dialysate pump carried by the enclosure and arranged to pump dialysate to a patient or dialyzer;
- at least one container connected fluidly to the dialysate pump;
- a load cell positioned to weigh dialysate located within the at least one container;
- an accelerometer positioned and arranged to detect a force imparted on at least one of the enclosure and the container;
- and
- electronics configured to receive a first signal from the load cell and a second signal from the accelerometer and process the first and second signals so as to determine if an abnormality sensed by the load cell is a system error or a mechanical interference.

- a load cell positioned to weigh dialysate located within the at least one container;
- an accelerometer positioned and arranged to detect a force imparted on at least one of the enclosure and the container;
- and
- electronics configured to receive load cell data from the load cell and accelerometer data from the accelerometer and process the load cell and accelerometer data to determine if (i) the dialysis system is operating properly;
- (ii) a system error has occurred;
- or (iii) a mechanical interference has occurred.
