Abstract
Systems and methods of generating a customized dialysate solution are provided. The system and methods use stock concentrates, with the addition of spikes to generate a customized dialysate solution based on the needs of the patient.
Claims19
A method, comprising the steps of:
- adding a base concentrate to a concentrate reservoir of a dialysate system wherein the base concentrate contains one or more of potassium, magnesium, calcium, and glucose;
- customizing a dialysate by adding one or more spikes to the concentrate reservoir containing the base concentrate wherein the spikes are selected from the group of potassium, magnesium, calcium, glucose, and combinations thereof;
- conveying fluid from the concentrate reservoir to a dialysate flow path at a set ratio to obtain a dialysate with a predetermined solute concentration based on a dialysate prescription;
- wherein the set ratio is a ratio of a dialysate flow rate to a concentrate flow rate;
- and
- sensing a conductivity of dialysate in the dialysate flow path downstream of the concentrate line using a sensor.
3 more elements
A dialysis system, comprising:
- a concentrate reservoir configured to contain a base concentrate solution wherein the concentrate reservoir is configured to receive one or more spikes and is fluidly connected to a dialysate flow path via a concentrate line, wherein the base concentrate contains one or more of potassium, magnesium, calcium, and glucose and wherein the spikes are selected from the group of potassium, magnesium, calcium, glucose, and combinations thereof;
- a concentrate pump for conveying fluid from the concentrate reservoir to the dialysate flow path;
- and
- a conductivity sensor in the dialysate flow path downstream of the concentrate line wherein the conductivity sensor determines a conductivity of dialysate in the dialysate flow path.
