Abstract
A method includes flowing spent dialysate through a spent dialysate line of a dialysis system into a fluid receptacle fluidly coupled to the spent dialysate line, reacting the spent dialysate with a chemical reagent contained within the fluid receptacle to generate a reacted sample, emitting electromagnetic radiation through the reacted sample using an emitter; detecting a level of one or more waste products present in the spent dialysate using a spectroscopy sensor positioned proximate the fluid receptacle.
Claims28
A method comprising:
- flowing spent dialysate through a spent dialysate line of a dialysis system into a fluid receptacle fluidly coupled to the spent dialysate line;
- reacting the spent dialysate with a chemical reagent contained within the fluid receptacle to generate a reacted sample;
- emitting electromagnetic radiation through the reacted sample using an emitter;
- and
- detecting a level of one or more waste products present in the spent dialysate using a spectroscopy sensor positioned proximate the fluid receptacle,
- wherein:
- flowing the spent dialysate from the spent dialysate line into the fluid receptacle comprises breaking a frangible connector to fluidly connect the spent dialysate line to the fluid receptacle;
- and
- the frangible connector is broken by a frangible breaking mechanism of a dialysis machine of the dialysis system.
6 more elements
A dialysis system comprising
- a dialysis machine;
- a spent dialysate line;
- and
- a spent dialysate testing system comprising:
- a fluid receptacle configured to receive spent dialysate from the spent dialysate line;
- a chemical reagent contained within the fluid receptacle and configured to react with the spent dialysate in the fluid receptacle to form a reacted sample;
- an emitter positioned at a first end of the fluid receptacle and configured to emit electromagnetic radiation;
- a spectroscopy sensor positioned at a second end of the fluid receptacle opposite the emitter and configured to detect an electromagnetic spectrum;
- and
- a frangible connector positioned between the fluid receptacle and the spent dialysate line, wherein:
- the dialysis machine is configured to break the frangible connector in response to the dialysis machine receiving user input through a user interface of the dialysis machine;
- breaking the frangible connector fluidly connects the spent dialysate line to the fluid receptacle and causes the spent dialysate to flow from the spent dialysate line into the fluid receptacle;
- and
- the frangible connector is broken by a frangible breaking mechanism of the dialysis machine of the dialysis system.
