  • Patent number: 8741147
    Abstract: 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.

  • Patent number: 4767526
    Abstract: Artificial kidney comprises a hemodialyzer connected in a dialysis liquid circuit which is in the form of a loop the volume of which is essentially invariable. The circuit is open to the atmosphere and comprises a circulating pump arranged upstream of the hemodialyzer. Means are provided for drawing off and measuring, outside the said circuit, amounts of liquid equal to the amounts of ultrafiltrate which it is desired to remove from a patient's blood stream. A variable hydraulic resistance is provided downstream of the hemodialyzer and comprises a float, the resistance being operative to keep the dialysis liquid at an essentially constant level in the circuit in order automatically to regulate the pressure of the dialysis liquid in the hemodialyzer.

  • Patent number: 4765888
    Abstract: An artificial kidney comprising a haemodialyser 16 connected to a dialysis liquid circuit. The latter can be entirely integrated, that is to say that the functions previously performed by a plurality of self-contained members connected to one another are now performed by a common unit consisting of a very small number of multifunctional components. This common unit is preferably disposable. A small console groups together, with their electric circuits, the re-usable means for controlling and checking the artificial kidney.

  • Patent number: 4623450
    Abstract: An artificial kidney comprising a haemodialyser (a) associated with and preferably integrated into a common unit D adapted to be connected simultaneously to a patient P, to a container 34 of fresh and/or used dialysis liquid, and to a controlling and checking console (h). The disposable common unit can perform all the functions necessary for a treatment. These functions are not performed by self-contained members, but by a small number of flexible multifunctional parts, such as elements 14 and 15, each cooperating with rigid parts such as parts 10, 11, 12 and 13.

  • Patent number: 4617115
    Abstract: An artificial kidney comprising a haemodialyser connected to a dialysis liquid circuit has the dialysis liquid circuit designed and simplified so as to be entirely disposable. Preferably, the haemodialyser and also all the circuits for the blood, for the dialysis liquid and for removing the ultrafiltrate are disposable. They can be delivered in a disposable container which can, during treatment, be used as a support and as a dialysis liquid reservoir. A small console includes the re-usable means for controlling and checking the artificial kidney, together with their electric circuits.
