An air purging method includes: (a) detecting a low fluid level in a blood circuit indicating a high amount of air in the blood circuit; (b) stopping a blood pump; (c) closing a venous patient line; (d) opening a blood circuit air vent valve and a drain valve; and (e) running the blood pump to meter air through the air vent valve and the drain valve to a drain.

An example renal therapy system includes a blood pressure monitor configured to output blood pressure data concerning a patient and a renal therapy machine communicatively coupled to the blood pressure monitor. The renal therapy machine is configured to generate ultrafiltration (“UF”) removed data from a prescribed renal therapy treatment performed by the renal therapy machine on the patient, and transmit the UF removed data and the blood pressure data via a network. At least one of a UF trend or a blood pressure trend from the UF removed data or the blood pressure data is determined, enabling a further determination as to at least one of (a) whether a prescribed renal therapy treatment adjustment or a new prescribed renal therapy treatment needs to be made, (b) whether the patient is complying with the prescribed renal therapy treatment, or (c) whether a condition related to an alarm or an alert exists.

A security token is provided having a communication interface with a communication transceiver; a circuit having encoded thereon an immutable hardware key; and a tangible, nonvolatile memory, the nonvolatile memory having stored thereon a mutable software key, the mutable software key including a cryptographic key and an expiry for the cryptographic key.

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.

Systems and methods of generating and regenerating peritoneal dialysate are provided. The systems and methods use a dialysate regeneration module, a sterilization module and concentrates to prepare peritoneal dialysate from used peritoneal dialysate or source water. An optional integrated cycler for direct infusion of the generated peritoneal dialysate is included. Optional dialysate storage containers are provided for storage of the peritoneal dialysate prior to use.

Systems and methods of generating peritoneal dialysate are provided. The systems and methods use a water purification module, a sterilization module and concentrates to prepare a bolus of peritoneal dialysate from source water for use with an non-integrated cycler.

The present invention relates to an apparatus for carrying out a tidal peritoneal dialysis treatment of a patient, wherein the dialysis treatment comprises a sequence of cycles which each have a filling period, a dwell period and a drain period, wherein the apparatus has at least one cycler which is suitable for filling the abdominal cavity of the patient with a specific inflow volume of fresh dialysis solution up to a reaching of a specific patient volume in the filling period and for emptying consumed dialysis solution from the abdominal cavity of the patient up to a reaching of a specific tidal outflow target in the drain period, wherein the apparatus furthermore has at least one processor which controls the cycler in at least one operating mode such that the drain period is ended before reaching the tidal outflow target so that a permitted residual volume remains in the abdominal cavity and then a switch is made to a filling period and in that the filling period is carried out such that the filling volume of the patient lies at a permitted patient volume above the specific patient volume on the completion of the filling period.

A peritoneal dialysis system includes (i) a fill container, and (ii) an energizing unit that removably accepts the fill container, the energizing unit including a sterilization source so configured and arranged relative to the fill container when accepted by the energizing unit to place fluid within the fill container in a physiologically safe condition for delivery to the peritoneal cavity of a patient.

The present invention relates to an apparatus for determining the peritoneal pressure in the abdomen of a patient and/or for determining the drainage state of the abdomen of a patient, wherein the apparatus comprises at least one pump for conveying a dialysis solution into the abdomen as well as at least one measurement device for measuring the pressure in the dialysis solution, wherein the apparatus comprises at least one control unit that is configured such that it controls the pump and the measurement device such that a first measurement of the pressure is carried out by the measurement device with a stationary pump to obtain a first measured pressure value, the pump is subsequently put into operation to convey a partial volume of the total inflow volume of the dialysis solution into the abdomen, and the pump then stops, and then a second measurement of the pressure is carried out by the measurement device to obtain a second measured pressure value.
