PROBLEM TO BE SOLVED: To provide a filtration method for purification of protein.SOLUTION: A method is disclosed for filtering a protein in a liquid mixture in a manner not substantially impairing the recovery of the protein in filtration filtrate or not in a differently limited manner. The method generally includes passing the liquid mixture containing a protein (e.g., an aqueous vWF mixture) through a filter while applying a counter pressure to the liquid mixture filtrate to accurately reduce and control the pressure differential across the filter. The disclosed method has the advantage that relatively high filtration flow rates can be achieved at relatively low pressure differentials, in contrast to high pressure differentials, which actually reduce the filtration flow rate of protein liquid mixtures. Further, the method can recover substantially all of the protein that is initially present in the liquid mixture.

PROBLEM TO BE SOLVED: To provide a composition for use in bone healing and bone regeneration.SOLUTION: There is provided a composition for use in bone healing and bone regeneration in the form of a viscoelastic hydrogel gel or liquid formulation comprising fibrinogen, thrombin and an inorganic component comprising a strontium (Sr)-containing compound. The strontium-containing compound can be dissolved in thrombin solutions or added to clot in crystalline particulate form. Upon mixing the components, gelation takes place to form a matrix. The composition may also comprise an iodine-containing compound which acts as a plasticizer.

PROBLEM TO BE SOLVED: To provide an improved dialysis system and a method for performing dialysis.SOLUTION: Used dialysate from a peritoneal cavity of a patient 16 passes a dialyzer 26 having a membrane for separating a waste component from the used dialysate along a patient loop 12, which returns fresh dialysate to the peritoneal cavity of the patient. The waste component enters a second regenerating loop 14 and is carried away by a regenerating unit absorbing the waste component or a sorbent cartridge 32. The regenerating unit removes an undesired component in the dialysate removed from the patient loop by the dialyzer, for example, excessive fluids (ultrafiltrate, or UF), toxin and a metabolic waste. The system can add a desired component such as glucose and electrolyte to the dialysate. An additive supports maintenance of an osmotic gradient of a patient suitable for performing the dialysis, and provides a compound required for the patient.

PROBLEM TO BE SOLVED: To provide systems and methods for detecting patient access disconnection.SOLUTION: Apparatuses, devices, systems and methods for detecting access disconnection are provided. The present invention includes electrical contacts 12 in fluid and electrical communication with a fluid passing between a patient and a medical system during therapy. In this regard, the present invention can use a direct-contact measurement to detect access disconnection, such as dislodgement of an access device from the patient through which the fluid can flow during therapy including medication delivery, dialysis therapy and the like.

PROBLEM TO BE SOLVED: To provide a multiple-chamber container with a mistake proof administration system.SOLUTION: The multiple-chamber container (10) that includes a container body sealed around a peripheral edge (14) and having an outlet (16). The container also includes a first peel seal (18) having a projecting portion (42) and a second peel seal (20) that isolates the outlet (16). The second peel seal may also include a projecting portion (44). The first and second peel seals (18) and (20) may be configured to define a symmetric chamber. The chamber may include an axis of symmetry extending between the first and second projecting portions (42) and (44). The chamber geometry of the container ensures a correct sequential opening of the first and second peel seals (18) and (20).
