SYSTEMS AND METHODS FOR DIALYSIS FLUID PREPARATION IN BATCH DISPOSABLE
A peritoneal dialysis system includes a water purifier; a disposable set including a water line in fluid communication with the water purifier, a drain line for draining from the disposable set, and a disposable container including at least one chamber, the disposable container including at least one concentrate in one of the at least one chamber, and the disposable container positioned and arranged to hold a dialysis fluid prepared by mixing water from the water purifier and the at least one concentrate; and a control unit in communication with at least one sensor, for detecting a first property of water from the water purifier and a second property of the dialysis fluid.
APPARATUS FOR PERFORMING PERITONEAL ULTRAFILTRATION
An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure. The apparatus comprises a dilution syringe for removal of a portion of peritoneal fluid from the peritoneal cavity. A glucose bag comprises glucose concentrate at a concentration of 30 %. A small amount of glucose concentrate is mixed with the dilution fluid in the dilution syringe in order to dilute the glucose concentrate to below 3 % concentration. Then, the mixture is filled into the peritoneal cavity from the dilution syringe in order to replenish the glucose in the peritoneal cavity for maintaining a substantially constant glucose concentration in the peritoneal cavity. In addition, peritoneal fluid is intermittently removed from the peritoneal cavity for counteracting increased intraperitoneal fluid volume and increased intraperitoneal pressure due to ultrafiltration. A UF bag is arranged for receiving such surplus peritoneal fluid. A glucose syringe may be arranged for metering the glucose concentrate.
Fluid line autoconnect apparatus and methods for medical treatment system
A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.
SYSTEMS AND METHODS FOR PERITONEAL DIALYSIS HAVING POINT OF USE DIALYSIS FLUID PREPARATION USING WATER ACCUMULATOR AND DISPOSABLE SET
Disclosed herein is a disposable set for operation with first and second concentrate containers in fluid communication with first and second concentrate container connectors. The disposable set includes a pumping cassette comprising at least a first concentrate port and a second concentrate port. The disposable cassette also includes a first concentrate line in fluid communication with the first concentrate port and a second concentrate line in fluid communication with the second concentrate port. The first concentrate line terminates at a first concentrate line connector having a first configuration for mating with the first concentrate container connector. The second concentrate line terminates at a second concentrate line connector having a second, different configuration for mating with the second concentrate container connector, such that the first concentrate line connector cannot mate with the second concentrate container connector and the second concentrate line connector cannot mate with the first concentrate container connector.
DISPOSABLE COMPONENTS FOR FLUID LINE AUTOCONNECT SYSTEMS AND METHODS
Components for a medical infusion fluid handling system, such as an APD system, in which one or more lines (such as solution lines), spikes or other connection ports may be automatically capped and/or de-capped. This feature may provide advantages, such as a reduced likelihood of contamination since no human interaction is required to de-cap and connect the lines, spikes or other connections. For example, a fluid handling cassette may include one or more caps that cover a corresponding spike and include a raised and/or recessed feature to assist in removal of the cap from the cassette. A solution line cap may include a hole and recess, groove or other feature to engage with a spike cap and enable removal of the cap.
Peritoneal Dialysis Systems, Devices, and Methods
An automated peritoneal dialysis system provides both cycler-assisted peritoneal dialysis treatment and also continuous ambulatory peritoneal dialysis (CAPD). The system includes a fluid preparation and treatment device with a concentrate dilution components connected to a source of purified water and medicament concentrate. The treatment device has at least one mixing container connected via a pump and valves to the sources, the valves and the pump mixing and diluting the concentrate to form a medicament. An auxiliary port is provided for attaching a CAPD container and for receiving medicament. A controller is programmed to control the fluid preparation and treatment device to implement one or more cycler-assisted peritoneal dialysis treatment cycles using medicament from the mixing container and also to control the preparation of additional dialysate at the end of the cycler-assisted peritoneal dialysis treatment cycles to dispense additional dialysate through the auxiliary port for use in CAPD.
Drain and fill logic for automated peritoneal dialysis
A system for performing a peritoneal dialysis therapy includes at least one dialysis fluid pump, and a control unit operable with the at least one dialysis fluid pump to perform a plurality of peritoneal dialysis cycles, the cycles including a fill phase, a dwell phase and a drain phase. The control unit configured to (i) store a previously entered continuous cycling peritoneal dialysis (CCPD) therapy having a total prescribed fresh dialysate fill volume delivered over n cycles, the cycles performed over a total therapy duration, and (ii) automatically convert the CCPD therapy into a tidal peritoneal dialysis therapy having n+1 cycles, less a number of cycles already completed during the CCPD therapy, using the total prescribed fresh dialysis fill volume, and maintaining the total therapy duration.
AUTOMATED PERITONEAL DIALYSIS CYCLER HAVING GRAVIMETRIC CONTROL
A peritoneal dialysis (PD) system includes a cycler having a weigh scale, a chamber for weighing by the weigh scale, a heater, a plurality of valves, a pump, and a control unit operable with the weigh scale, the heater, the plurality of valves and the pump; and a disposable set including a PD fluid container fitting within the chamber for weighing and heating, a supply line in fluid communication with the PD fluid container, a drain container fitting within the chamber for weighing, a drain line in fluid communication with the drain container, and a patient line positioned on an opposing side of the pump from the supply line and the drain lines, wherein the control unit is configured to operate the plurality of valves and the pump to pump used dialysis fluid to the drain container and fresh dialysis fluid from the PD fluid container.
