摘要： A medical filter (11) is constructed as a container with an interior volume in open fluid communication with a patient connection element (31) and a transport connection element (39). Filter support structure (13), mounted within the interior, is structured as a thin, perforated member (14) carrying hydrophilic filter medium (17). A first flow path directs spent dialysate from the patient across the surface of the filter medium (17) to the transport connection (39). A second flow path directs fresh dialysate from the transport connection (39) through the filter medium (17) and the perforated support structure (13) to the patient connection (31).

摘要： A pump assembly for ambulatory peritoneal dialysis transfer procedures includes a portable power supply (120) geared to drive a high volume peristaltic pump (100). A cassette (250) of the pump comprises an encasement (200); tubing (140) including an inner portion positioned within the encasement, a patient-side portion (160) for connection to an indwelling peritoneal dialysis catheter and an opposing portion (150) connectible to a system for containment, and communication of a peritoneal dialysis solution which may be one single-compartment bag assembly; a safety valve (260) for selectively occluding and permitting the communication of the solution through the inner portion; and a filter preferably interposed along the patient-side portion which filters air and particles from peritoneal dialysate that is flowing toward a patient which allows peritoneal dialysate to flow substantially freely, and unfiltered away from the patient.
