A hollow-fiber-type blood processing device and methods for its manufacture include a hollow fiber membrane bundle which is obtained by bundling a large number of hollow fiber membranes into a columnar shape. A sheet body is mounted on an outer peripheral portion of the hollow fiber membrane bundle. The sheet body is expandable as a result of being woven from a sheet material. An inner diameter of the sheet body in a natural state where no external force is applied to the sheet body is smaller than the outer diameter of the hollow fiber membrane bundle.

A renal therapy machine includes a blood filter including a plurality of porous fibers; a blood circuit in communication with the blood filter; and a dialysate circuit in communication with the blood filter and operable with at least one pump, wherein the renal therapy machine is configured to perform a priming sequence in which a physiologically compatible solution, other than dialysate, primes the blood circuit and is flowed within the fibers and through pores in the fibers of the blood filter, and the pump of the dialysate circuit vents air from the blood filter into the dialysate circuit.

The present invention relates in part to a filter comprising a tubular housing having a proximal end, a distal end and a housing lumen therethrough; a tubular membrane having a proximal end, a distal end and a membrane lumen therethrough, wherein the tubular membrane is positioned within the housing lumen; a contaminated fluid sample inlet fluidly connected to the proximal end of the membrane, and a contaminated fluid sample outlet fluidly connected to the distal end of the membrane, thereby creating a sample flow-path from the sample inlet through the membrane lumen to the sample outlet; and a purification material inlet fluidly connected to a distal region of the housing lumen, and a purification material outlet fluidly connected to a proximal region of the housing lumen, thereby creating a purification material flow-path from the purification material inlet through the housing lumen to the purification material outlet; wherein the direction of the sample flow-path is in the opposite direction of the purification material flow-path. The invention also relates a method of purifying a contaminated fluid using said filter.

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.

The invention concerns a device comprising a base (2) and a door (20), said device having a closed door position in which a circuit (8) of the device comprises a bag comprising two flexible films and connectors of the conveying network, and a press (9) comprising a first she (16) disposed on a front face (5) of said base (2) and a second shed (17) disposed in said door (20); and a hinge system hinging said door (20) relative to said base (2), and disposed only on one side of said door (20) so as to form lateral clearances between said door (20) and said base (2) over the rest of a perimeter of said door (20).

The invention concerns a device comprising: a base (2); a moveable or removable door (20), said device having a closed door position; and in the closed door position, a circuit (8) comprising a bag comprising two flexible films and conveying network connectors, and a press (9) comprising a first shell (16) disposed on said front face (5) of said base (2) and a second shell (17) disposed in said door (20); said bag being clamped between said first shell (16) and said second shell (17) in a state in which conduits of said network for conveying liquid are formed between said films.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface, a heater in thermal communication with the planar surface, and a sodium sensor in electromagnetic communication with the planar surface. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement with a warm water inlet and a cold water inlet in fluid flow communication with a temperature mixing component. The thermostatic mixing component mixes the cold water and the warm water to produce mixed water maintained at a predetermined temperature between the temperature of the cold water and the temperature of the warm water. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer, thermostatic mixing component, a trap primer, or any combination of the foregoing.
