Abstract:
The present invention relates to a disposable flexible bag for dialysis concentrate comprising a primary bag and an overpouch designed to ensure that the overpouch remains on the primary bag during use of the concentrate to prevent water evaporation that could lead to an out-of-specification situation towards the end of the in-use period.
Abstract:
A system for purifying incoming fluid is provided that is modular and includes a heat exchanger module, an evaporator-condenser module and a compressor. The system is configured to facilitate passive drainage of the purified fluid for collection. The system components are arranged in a stacked configuration to facilitate gravitational flow of the purified fluid such that the purified fluid drains passively for collection. A system for preparation of ready-to-use treatment fluid is also provided including the modular fluid purification system, a preparation station and a coupling device. The components are configured to be retained in a portable carrier that is manually operable for improved access to and mobility of the components. A coupling device for use in connecting flow channels of a plurality of components and for use in preparing ready-to-use dialysate is also provided, A further system for preparation of a receptacle and a ready-to-use treatment fluid in the receptacle is provided.
Abstract:
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.
Abstract:
An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a tube set including a connector for connection to a patient line for access to the peritoneal cavity of the patient. A flow pump is arranged for addition and removal outflow and inflow (recirculation) of fluid from/to the peritoneal cavity. An osmotic agent peristaltic pump is arranged for replenishment of glucose solution to the fluid added to the peritoneal cavity for promoting ultrafiltration. The glucose is replenished intermittently for keeping a concentration of glucose substantially constant in the peritoneal cavity. The flow pump comprises a pressure chamber with rigid walls and a flexible pump bag arranged therein. An air pump pressurizes the chamber for outflow of fluid from the peritoneal cavity by a sub pressure and inflow of fluid to the peritoneal cavity by an overpressure, which pressures are maintained within safe limits.
Abstract:
In one embodiment an automated peritoneal dialysis (“APD”) machine 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 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:
Pumping cassettes are disclosed. Each cassette includes a housing, at least one fluid inlet and at least one fluid outlet as well as at least one reciprocating pressure displacement membrane pump in fluid relation to the cassette. The balancing cassette includes at least one balancing pod in fluid connection. The mixing cassette includes at least one mixing chamber in fluid connection. The system includes a mixing cassette, a balancing cassette, and an outer or middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.
