Embodiments of the present disclosure include a dialysis system having a disposable cartridge which includes one or more flowpaths arranged on or within the cartridge, where the one or more flowpaths including at least one of a blood flowpath for carrying a volume of blood to be treated in a dialyser and a dialysate flowpath, isolated from the blood flowpath, for delivering a flow of dialysate solution through the dialyser.

Systems and methods for cleaning and disinfecting a medical therapy device that delivers any one of hemodialysis, hemodiafiltration and hemofiltration. The system has a base module that has at least one segment of a controlled compliant flow path and at least one pair of jumpered ports configured on the base module. One or more components have connections connectable to the jumpered ports of the base module to provide for fluid communication between the segment of the controlled compliant flow path in the base module and a flow path defined by the one or more components. The base module is connected to the one or more components that define a flow path configurable for carrying out in part at least one function performed during any one of hemodialysis, hemodiafiltration or hemofiltration.

A disposable cell enrichment kit includes a crossflow filtration device configured to be disposed along a main loop pathway and to receive a process volume containing a biological sample and utilize crossflow filtration, via a micro-porous membrane, to retain a specific cell population in a retentate from the process volume and to remove a permeate including certain biological components from the process volume. The crossflow filtration device includes a laminated filtration unit that includes the micro-porous membrane, a first mating portion, a second mating portion, and a membrane support. The membrane support includes a first plurality of structural features that define a first plurality of openings, wherein the first plurality of structural features are coupled to the micro-porous membrane and provide support to the micro-porous membrane, and the first plurality of openings allow the permeate to flow through them after crossing the micro-porous membrane.

Provided is a blood component collection cassette capable of measuring a circuit internal pressure using a simple and economical configuration.

A blood component collection cassette (28) includes an inflow line for sending blood or a blood component collected from a donor to a centrifugal separator (14), a return line for returning a predetermined blood component to the donor, and a line forming member forming one of the inflow line and the return line and having a load detection soft portion made of a soft material.

The invention relates to a medical fluid cassette and a medical hose set having a medical fluid cassette for receiving and/or carrying a medical fluid. The invention relates in particular to a blood hose set having a medical fluid cassette for the extracorporeal blood treatment. An easily manufactured insert having a clot filter is proposed, this insert being inserted or pushed into a receptacle, for example, a groove, in the interior of a chamber of the housing body of the medical fluid cassette.

The invention relates to an external function device which has at least one housing body having at least one chamber integrated into it for holding medical fluids and at least one locking device for releasably holding an accessory part.

Provided is a blood component collection cassette, a blood component collection kit, a blood component collection system, and a flow path internal pressure detection method capable of accurately measuring a circuit internal pressure in negative pressure and positive pressure regions.

A flow path (42) formed in a cassette body (40) of a blood component collection cassette (28) has a first line (42a) through which blood flows when a blood component separation device is in operation, and a second line (42b) through which blood does not flow when the blood component separation device is in operation. A first line forming member (54) is provided with a first pressure-receiving portion (60) pressed by a first load detector (88) attached to the blood component separation device. A second line forming member (56) is provided with a second pressure-receiving portion (62) pressed by a second load detector (90) attached to the blood component separation device.

A flow path is formed in a cassette body of a blood component collection cassette. The cassette body includes a bulging structure in which at least a portion of the flow path is formed. A first gripped member, which is configured to be gripped by a first gripping member provided on a centrifugal separation device, is disposed on one surface of the bulging structure in a thickness direction thereof. A second gripped member, which is configured to be gripped by a second gripping member to which a load detection unit that is provided on the centrifugal separation device is fixed, is disposed on another surface of the bulging structure in the thickness direction thereof.

A biological component collection system and a circuit internal pressure acquisition method are provided, which are capable of accurately measuring the circuit internal pressure. A centrifugal separation device of a blood component collection system comprises an estimated data calculation unit that calculates estimated data B on the basis of initial data A, and a correction unit that corrects the estimated data B in a manner so that the internal pressure calculated by a first internal pressure calculation unit becomes equivalent to the internal pressure calculated by a second internal pressure calculation unit.

A centrifugal separation device of a blood component collection system comprises a data acquisition unit that acquires initial data A, an estimated data calculation unit that calculates estimated data B on the basis of the initial data A, a reaction force calculation unit which calculates a reaction force of a first applied load measurement unit on the basis of the estimated data B, and an internal pressure calculation unit that calculates an internal pressure of the first applied load measurement unit, based on the reaction force and a load detected by a first load detecting unit.
