Abstract

A method for a hybrid blood and peritoneal dialysis (“PD”) machine comprising: (i) determining whether a previous treatment left a last fill of dialysate in a patient's peritoneum; (ii) if a next treatment is a PD treatment, and if the previous treatment did not leave the last fill of dialysate, causing a PD treatment in which a first cycle is a fill cycle to be initiated; (iii) if the next treatment is a PD treatment, and if the previous treatment did leave the last fill of dialysate, causing a PD treatment in which a first cycle is a last fill drain cycle to be initiated; and (iv) if the next treatment is a blood treatment and if the previous treatment did leave the last fill of dialysate, causing a blood treatment including a last fill drain cycle to be initiated.

First claim

The invention is claimed as follows:

1 . A method for a hybrid blood treatment and peritoneal dialysis (“PD”) machine comprising:
(i) determining, via a machine processor, whether a next treatment is a PD treatment or a blood treatment;
(ii) if the next treatment is a blood treatment, providing, via a machine user interface, a blood treatment setup procedure; and
(iii) if the next treatment is a PD treatment, providing, via the machine user interface, a PD treatment setup procedure.

2 . The method of claim 1 , wherein if the next treatment is a PD treatment, determining, via the machine processor, whether a last fill of dialysate from a previous treatment needs to be removed from a patient.

3 . The method of claim 1 , wherein determining whether a next treatment is a PD treatment or a blood treatment includes providing, via the machine user interface, a selectable input to manually choose the PD treatment or the blood treatment.

4 . A hybrid blood treatment and peritoneal dialysis (“PD”) system comprising:
at least one processor and memory programmed to
(i) determine whether a next treatment is a PD treatment or a blood treatment;
(ii) if the next treatment is a blood treatment, provide a blood treatment setup procedure;
(iii) if the next treatment is a PD treatment, determine whether a subsequent treatment to the PD treatment is a PD treatment or a blood treatment;
(iv) if the subsequent treatment is a PD treatment, configure the next PD treatment to include a last fill of PD fluid that is left in a patient's peritoneum after the next PD treatment; and
(v) if the subsequent treatment is a blood treatment, configure the next PD treatment not to include the last fill of PD fluid.

5 . The system of claim 4 , which includes causing the at least one processor and memory to configure the machine so that a user can determine a therapy type for the next treatment.

6 . The system of claim 4 , which includes causing the at least one processor and memory to configure the machine so that the machine determines a therapy type for the next treatment.

7 . The system of claim 4 , which includes causing the at least one processor and memory to configure the machine to determine the therapy type for the next treatment according to (a) a prescribed schedule or (b) an algorithm.

8 . The system of claim 7 , wherein the algorithm is structured to perform a first therapy type for a predetermined number of consecutive days and perform a second therapy type for a same or different predetermined number of consecutive days.

9 . A hybrid blood treatment and peritoneal dialysis (“PD”) system comprising:
at least one processor and memory programmed to
(i) determine whether a next treatment is a PD treatment or a blood treatment;
(ii) if the next treatment is a blood treatment, provide, via a user interface, a blood treatment setup procedure; and
(iii) if the next treatment is a PD treatment, provide, via the user interface, a PD treatment setup procedure.

10 . The system of claim 9 , which includes causing the at least one processor and memory to, if the next treatment is a PD treatment, determine whether a last fill of dialysate from a previous treatment needs to be removed from a patient.

11 . The system of claim 9 , wherein determining whether a next treatment is a PD treatment or a blood treatment includes evaluating a manual input selecting the PD treatment or the blood treatment.

12 . The system of claim 9 , wherein the at least one processor and memory are further programmed to:
(iv) determine whether a previous treatment was a PD treatment, and (v) if the previous treatment was a PD treatment, determine whether the previous treatment left a last fill of dialysate in the patient's peritoneum using:
(a) data about the previous treatment already stored in the machine;
(b) data about the previous treatment entered manually into the user interface; or
(c) data from a device in fluid communication with a catheter implanted in the patient's peritoneum.

13 . The system of claim 12 , wherein determining whether the previous treatment left a last fill of dialysate in the patient's peritoneum includes attempting to drain the patient and looking for fluid.

14 . The system of claim 13 , wherein if fluid is found, causing the at least one processor and memory to:
determine that the previous treatment left the last fill of dialysate; and if no fluid is found, sense for an obstruction in a patient line and/or a catheter, and if no obstruction is sensed, determining that the previous treatment did not leave a last fill of dialysate.

15 . The system of claim 14 , wherein sensing for an obstruction includes attempting to deliver an amount of fluid to the patient and sensing for an increase in pressure.

16 . The system of claim 9 , wherein the at least one processor and memory are further programmed to, if the next treatment is a blood treatment, and if the previous treatment left a last fill of dialysate in the patient's peritoneum, to perform a last fill drain cycle before, during or after the blood treatment.
