AUTOMATED DIALYSIS SYSTEM DRIVEN BY GRAVITY AND VACUUM
First Claim
1. A peritoneal dialysis machine comprising:
- a supply bag;
an apparatus configured to support the supply bag, the supply bag located above the peritoneal cavity of a patient;
a vacuum source;
a patient line configured to be connected to the patient;
a drain line configured to be connected to a drain; and
a logic implementor configured to enable;
(i) fresh dialysate to be gravity fed from the supply bag through the patient line to the peritoneal cavity during a fill cycle; and
(ii) the vacuum source to cause spent dialysate to be pulled from the peritoneal cavity through the drain line to the drain during a drain cycle.

Abstract
A peritoneal dialysis machine includes: (i) a supply bag; (ii) an apparatus configured to support the supply bag, the supply bag located above the peritoneal cavity of a patient; (iii) a vacuum source; (iv) a patient line configured to be connected to the patient; (v) a drain line configured to be connected to a drain; and (vi) a logic implementor configured to enable (a) fresh dialysate to be gravity fed from the supply bag through the patient line to the peritoneal cavity during a fill cycle and (b) the vacuum source to cause spent dialysate to be pulled from the peritoneal cavity through the drain line to the drain during a drain cycle.

15. A peritoneal dialysis machine comprising:
-
a supply bag; an apparatus configured to support the supply bag, the supply bag located above the peritoneal cavity of a patient; a patient line configured to be connected to the patient; a drain line configured to be connected to a drain; a vacuum source in pneumatic communication with the drain; and a logic implementor configured to enable;
(i) fresh dialysate to be gravity fed from the supply bag through the patient line to the peritoneal cavity during a fill cycle; and
(ii) the vacuum source to apply a negative pressure to the drain to cause spent dialysate to be pulled from the peritoneal cavity through the drain line to the drain during a drain cycle. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A peritoneal dialysis machine comprising:
-
a fresh dialysate container; an apparatus configured to support the fresh container, the fresh container located above the peritoneal cavity of a patient; a patient line configured to be connected to the patient; a spent dialysate container; a vacuum source in pneumatic communication with a chamber surrounding the spent container; and a logic implementor configured to enable;
(i) fresh dialysate to be gravity fed from the fresh container through the patient line to the peritoneal cavity during a fill cycle; and
(ii) the vacuum source to apply a negative pressure to the chamber to cause spent dialysate to be pulled from the peritoneal cavity to the spent container during a drain cycle. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
