A controller for blood treatment equipment comprising a treatment unit including a semipermeable membrane separating the treatment unit into a first compartment for the circulation of blood and a second compartment for the circulation of a treatment liquid is enclosed. The controller is adapted to receive one or more entries of information measured during the course of a treatment procedure, to calculate from said measured information a value of a significant parameter indicative of the progress of an extracorporeal blood treatment carried out by the equipment. The controller is also adapted to compare the calculated significant parameter to a prescribed reference value for the same parameter and to generate at least one output control signal responsive to said comparison for automatically controlling one or more operations performed by the equipment. Equipment comprising the controller and a control method the controller can be programmed to carry out are also disclosed.

Control apparatus and control method for a blood treatment equipment

It is disclosed a controller for a blood treatment equipment comprising at least a treatment unit including a semipermeable membrane separating the treatment unit in a first compartment for the circulation of blood and in a second compartment for the circulation a of a treatment liquid; the controller is adapted to receive one or more entries of measured information measured during the course of a treatment procedure, calculate from said measured information a value of at least a significant parameter indicative of the progress of an extracorporeal blood treatment carried out by the equipment, wherein the controller is also adapted to compare said calculated significant parameter to at least a prescribed reference value for the same parameter, and to generate at least one output control signal responsive to said comparison for automatically controlling one or more operations performed by the equipment. The invention relates also to an equipment comprising the controller and to a control method the controller can be programmed to carry out.

The invention concerns a hollow fibre separatory device. The opened ends of the hollow fibres are situated in a plane which is at an acute angle relative to the axes of end sections of the fibres. A reservoir is provided which defines a fluid flow passage leading across the open ends of the fibres from a region adjacent the acute angle at the periphery of the plane to the opposing peripheral region. Fibre end openings are signficantly larger than the normal open cross-sectional area. Also disclosed are processes for producing the hollow fibre separatory devices. Including in particular a novel procedure for introducing solidifiable sealing material at an acute angle relative to the ends of hollow fibres.
