Abstract

A peritoneal dialysis system includes a logic implementer configured to: (i) generate a number of peritoneal dialysis therapy regimens that meet at least one therapy target input; (ii) accept a filter input; and (iii) filter the generated therapy regimens according to the filter input to refine the number of therapy regimens available for selection.

Claims

1. A peritoneal dialysis system comprising:

equipment configured to perform peritoneal dialysis; and

a logic implementer configured to;

(i) accept at least one therapy target input selected from the group consisting of (a) minimum urea clearance, (b) minimum urea Kt/V, (c) minimum creatinine clearance, (d) minimum glucose absorption, and (e) ultrafiltration removed;

(ii) generate a number of peritoneal dialysis therapy regimens for the equipment that meet the at least one accepted therapy target input, each of the number of peritoneal dialysis therapy regimens including at least (a) therapy time, (b) fill volume, and (c) a number of cycles or a total therapy volume;

(iii) accept a filter input; and

(iv) filter the generated therapy regimens according to the accepted filter input to refine the number of therapy regimens available for selection.

2. The peritoneal dialysis system of claim 1, wherein the equipment includes an automated peritoneal dialysis (“

APD”

) machine configured to run one of the refined number of therapy regimens, the APD machine located remotely from the logic implementer.

3. The peritoneal dialysis system of claim 1, the at least one therapy target input being a threshold value above or below which the input is satisfied.

4. The peritoneal dialysis system of claim 1, the logic implementer further configured to accept at least one additional input used to generate the number of therapy regimens that meet the at least one therapy target input, the at least one additional input selected from the group consisting of:

(i) a solution type input, (ii) a solution dextrose level input, (iii) a therapy time input, and (iv) a fill volume input.

5. The peritoneal dialysis system of claim 4, the solution type input including a selection of one solution from a plurality of different types of solutions.

6. The peritoneal dialysis system of claim 4, the solution dextrose level input including a selection of one solution dextrose level from a plurality of predefined solution dextrose levels.

7. The peritoneal dialysis system of claim 6, the therapy time input including a setting of a minimum and maximum total time for therapy.

8. The peritoneal dialysis system of claim 4, the therapy fill volume input including at least one of:

(i) a setting of a minimum and maximum total fill volume, and (ii) a setting of a minimum and a maximum cycle fill volume.

9. The peritoneal dialysis system of claim 4, wherein at least one of inputs (i) to (iv) is made for at least two of:

(i) a night fill, (ii) a last night fill, and (iii) a day fill.

10. The peritoneal dialysis system of claim 1, wherein the filter input is at least one of:

(i) a non-clinical input, and (ii) based on a patient preference.

11. The peritoneal dialysis system of claim 1, wherein the filter input is based on at least one of:

(i) a solution cost;

(ii) a solution bag weight, (iii) a glucose level, (iv) a night therapy time, (v) a day fill volume, (vi) a night fill volume, (vii) a night therapy time, (viii) a urea Kt/V range, (ix) a creatinine clearances range, (x) a 24 hour UF range, (xi) a glucose absorbed range, (xii) a yes/no for dry day input, (xiii) a yes/no for last fill input, (xiv) a yes/no for allow least last fill plus one day exchange input, (xv) a yes/no for allow last fill plus two day exchange input, and (xvi) a yes/no for allow last fill plus three day exchanges.

12. The peritoneal dialysis system of claim 1, wherein the therapy time is selected from the group consisting of:

total therapy time and dwell time.

13. A peritoneal dialysis system comprising:

equipment configured to perform peritoneal dialysis; and

a logic implementer configured to;
