A peritoneal dialysis system includes: a drain container; a drain line placed in fluid communication with the drain container and configured to be placed in fluid communication with a patient's peritoneal cavity; a vacuum source configured to apply a pneumatic force to cause used dialysis fluid to flow through the drain line from the patient's peritoneal cavity to the drain container; a weight sensor configured to output a weight of used dialysis fluid delivered to the drain container from the patient's peritoneal cavity; and a controller configured to: (i) determine an actual flow rate of used dialysis fluid removed from the patient's peritoneal cavity based on the output from the weight sensor; (ii) compare the actual flow rate to a desired flow rate; and (iii) adjust the pneumatic force applied by the vacuum source to attempt to match the actual flow rate to the optimal flow rate.

Systems for performing peritoneal dialysis using vacuum source and weight sensor

A method of performing peritoneal dialysis includes: (i) locating a supply of fresh dialysis fluid above a patient's peritoneal cavity; (ii) locating a drain or a drain container below the patient's peritoneal cavity; (iii) connecting a supply line to the supply of fresh dialysis fluid and the patient's peritoneal cavity; (iv) connecting a drain line to the patient's peritoneal cavity and the drain or drain container; (v) pneumatically opening a supply line valve during a fill cycle; (vi) gravity filling the patient's peritoneal cavity with the supply line valve open during the fill cycle; (vii) pneumatically opening a drain line valve during a drain cycle; and (viii) draining the patient's peritoneal cavity with the drain line valve open during the drain cycle.

Method of performing peritoneal dialysis using pneumatic valves

A peritoneal dialysis machine includes: (i) a housing; (ii) an actuator carried by the housing so as to be able to interact with a peritoneal dialysis fluid carrying disposable; (iii) at least one heating element carried by the housing; (iv) a heater pan providing an upper surface of the housing, the heater pan cooperating with the at least one heater element to provide heat to a container of peritoneal dialysis fluid placed onto the heater pan, the container being part of or in communication with the peritoneal dialysis fluid carrying disposable; and (iv) a weight sensor cooperating with the heater pan to sense the weight of the peritoneal dialysis fluid located within the container.

Peritoneal dialysis system having heater pan and weight sensor

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.
