A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a member for removably securing a medical fluid tube is provided. The member includes a body providing a first fluid pathway and an opening for removably receiving an end of the medical tube. The first fluid pathway is placed in fluid communication with a second fluid pathway defined by the tube when the end of the tube is removably receiving. The member further includes a filter so positioned and arranged so as to cause fluid flowing through the first fluid pathway to pass through the filter, the filter allowing air but not liquid to flow through the first fluid pathway.

The present invention provides automated peritoneal dialysis systems, methods of operating the systems and devices for performing same. A typical therapy performed by the present invention begins by draining dialysis solution that is already in the patient's peritoneal cavity. The system pumps fresh dialysate from one of a plurality of supply bags, through an in-line heater to the patient's peritoneal cavity. After a dwell period, the spent dialysate in the cavity is pumped out of the patient to a drain or other disposal means. The system then pumps fresh dialysate from the supply bags to the patient and the procedure is repeated as defined in the therapy protocol. The system can pump a last bag of dialysate to the peritoneal cavity for an extended dwell, such as a daytime dwell.
