An intraperitoneal pressure ('IPP') measurement apparatus is disclosed herein. In an example, the IPP measurement apparatus includes a transfer set or catheter that is fluidly coupled to a patient's peritoneal cavity and a pressure sensor adapted to contact the transfer set or catheter. The pressure sensor is configured to transmit output data indicative of an IPP within the patient's peritoneal cavity. The pressure sensor includes a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter. The pressure sensor also includes a pressure amplifier having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element. The first side has a greater diameter or surface area compared to the second side for amplifying the pressure signal for the IPP measurement.

Intraperitoneal pressure ('IPP') measurement methods, apparatuses, and systems

A peritoneal dialysis ('PD') system includes a cycler including an actuation surface having a peristaltic pump actuator; at least one pair of capacitive sensing plates; a manifold assembly including a rigid manifold having at least one chamber, the rigid manifold configured and arranged to be abutted against the actuation surface for operation, wherein the at least one pair of capacitive sensing plates is positioned to be operable with the at least one chamber; a peristaltic pump tube; and a control unit configured to actuate the peristaltic pump actuator to pump dialysis fluid to the at least one chamber, receive a signal from the at least one pair of capacitive sensing plates, count a number of revolutions of the peristaltic pump actuator, determine a current volume per revolution for the peristaltic pump actuator, and use the current volume per revolution for a subsequent operation of the peristaltic pump actuator.

Peritoneal dialysis system including manifold assembly and peristaltic pump

A peritoneal dialysis ('PD') system includes a cycler including an actuation surface having a peristaltic pump actuator; a manifold assembly including a rigid manifold having first and second chambers (a,b), the rigid manifold configured and arranged to be abutted against the actuation surface for operation, a peristaltic pump tube (gh) extending from the first chamber (a) to the second chamber (b) of the rigid manifold, a dialysis fluid container line (b) extending from the first chamber (a), and a branch line (c) extending between the dialysis fluid container line (b) and the second chamber (b); and a control unit configured to cause the peristaltic pump actuator to actuate the peristaltic pump tube (gh) to pump dialysis fluid from the branch line (c) into the second chamber (b) and from the second chamber (b) into the first chamber (a).

A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient. The catheter facilitates mixing of fresh and spent dialysate inside the peritoneal cavity by inflowing fresh dialysate into the cavity at a location substantially separated from the cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.
