1. A peritoneal dialysis system comprising:
- a first pump actuator;
a second pump actuator;
first and second diaphragm pump chambers operable with the first and second pump actuators, respectively;
a pressure sensor located between the first diaphragm pump chamber and a fluid valve; and
a patient line in fluid communication with the fluid valve; and
wherein the system is configured to receive a signal from the pressure sensor and use the signal to modify a peritoneal dialysis treatment performed by the system.

Abstract
A peritoneal dialysis system includes: (i) a fluid cassette including diaphragm operated first and second pump chambers; (ii) a first pressure sensor operable with the first pump chamber; (iii) a second pressure sensor operable with the second pump chamber; and (iv) a to-patient port of the cassette in fluid communication with the first and second pump chambers, wherein the first pressure sensor is located between the first pump chamber and the to-patient port and the second pressure sensor is located between the second pump chamber and the to-patient port.

7. A peritoneal dialysis system comprising:
-
a first diaphragm operated pump chamber;
a second diaphragm operated pump chamber;
a first pressure sensor positioned to sense a fluid pressure exerted on the diaphragm of the first pump chamber;
a second pressure sensor positioned to sense a fluid pressure exerted on the diaphragm of the second pump chamber; and
wherein the system is configured to receive a signal from at least one of the pressure sensors and use the at least one signal to modify a peritoneal dialysis treatment performed by the system. - View Dependent Claims (8, 9, 10)

11. A peritoneal dialysis system comprising:
-
a fluid cassette including a diaphragm operated pump chamber;
a pressure sensor operating with the diaphragm, wherein fluid pumped via the pump chamber flows along the diaphragm at the pressure sensor; and
wherein the system is configured to receive a signal from the pressure sensor and use the signal to ensure that a pressure of the fluid inside a patient (“
IPP”
) does not exceed a pressure limit. - View Dependent Claims (12, 13, 14, 15)
