Abstract:
The present system and method in one embodiment limit a maximum instantaneous peritoneal volume to a comfortable level, while allowing the dialysis machine to advance to fill a prescribed volume whenever the drain ends after a minimum drain percentage has been attained. If a low drain condition occurs, the nominal fill volume is lowered and a therapy cycle is added, so that a prescribed total amount of fresh therapy fluid is used during therapy, maximizing therapeutic benefit. An allowable residual volume at the end of an incomplete drain is increased, thereby lowering the probability of a subsequent low drain condition.
Abstract:
A peritoneal dialysis system includes: a plurality of automated peritoneal dialysis ("APD") machines (102); and a server computer (118) in communication with the APD machines, the APD machines programmed to inform the server computer of how much dialysate is consumed over a first delivery period, the server computer configured to use the amounts consumed to determine dialysate delivery amounts for the plurality of APD machines for a second delivery period.
Abstract:
A peritoneal dialysis system includes a logic implementer configured to: (i) accept at least one therapy target input; (ii) accept at least one patient transport characteristic input; (iii) accept at least one solution input; (iv) accept at least one fluid volume input; (v) accept at least one therapy time input, at least one of the inputs (ii) to (v) including an input range; and (vi) generate each therapy regimen using the inputs of (ii), (iii), (iv) and (v), including each of the possibilities within the at least one input range, that satisfy the at least one therapy target input.

Abstract:
In one embodiment an automated peritoneal dialysis ("APD") machine (104) includes: at least one pump; a logic implementer storing a plurality of therapy prescriptions by which to operate the at least one pump, each therapy prescription pre-approved for a particular patient; and an input device (160) operating with the logic implementer to allow the patient to select one of the therapy prescriptions for a particular therapy. In another embodiment, the input device operating with the logic implementer allows a doctor/clinician to select or approve one of the therapy prescriptions to be run on the APD machine. In a further embodiment, the logic implementer is programmed to select or suggest one of the therapy prescriptions to be run on the is APD machine.
Abstract:
An access disconnection system (80) includes: a material (82) capable of absorbing blood from a patient upon an arterial or venous line disconnection; a light emitter (92) positioned to emit light onto the material; a light receiver (92) positioned to receive light reflected off of the material; and electronic circuitry (90) operably coupled to at least one of the light emitter and receiver, the circuitry configured to provide an output (i) when light received by the receiver reaches a particular level or (ii) indicative of an amount of light received by the light receiver.
Abstract:
A peritoneal dialysis system includes: an automated peritoneal dialysis ("APD") machine (102a) configured to remove ultraf iltrate ("UF") from a patient and record how much UF has been removed; and a logic implementer configured to (i) form a first moving average UF removed trend, (ii) determine a trending range around the first moving average UF removed trend, (iii) determine at least one of an upper and lower UF removed limit from the trending range, (iv) form a second moving average UF removed trend, and (v) alert if the second moving average UF removed trend moves outside of the at least one UF removed limit.

Abstract:
An ultrafiltration ("UF") evaluation method includes: (i) determining an amount of UF removed from a patient over a first dwell time; (ii) determine an amount of UF removed from the patient over a second, different dwell time; (iii) determining an amount of UF removed from the patient over a third, different dwell time; and (iv) fitting a curve to the UF removal amounts for the first, second and third dwell time. A peritoneal dialysis therapy generation method using the curve determined according to the "UF" evaluation method to generate at least one peritoneal dialysis therapy regimen.
