  • Publication number: 20100168641
    Abstract: A method and apparatus for controlling blood withdrawal and infusion flow rate with the use of a pressure controller. The pressure controller uses pressure targets based upon occlusion limits that are calculated as a function of flow. The controller has the ability to switch from controlling withdrawal pressure to controlling infusion pressure based upon the detection of an occlusion. The controller distinguishes between partial and total occlusions of the withdrawal vein providing blood access. Depending on the nature of occlusion, the controller limits or temporarily reverses blood flow and, thus, prevents withdrawal vessel collapse or reverses blood flow to quickly infuse blood into the vessel without participation from operator.

  • Publication number: 20100114002
    Abstract: A method for controlling the blood glucose level of a patient and periodically calibrating the glucose sensor using a calibration solution. The method controls the level of blood glucose in a patient through an extracorporeal blood circuit by: withdrawing blood from a vascular system in the patient to the extracorporeal circuit; removing ultrafiltrate from the withdrawn blood in the circuit; determining a level of glucose present in the blood based on the removed ultrafiltrate; infusing at least a portion of the removed ultrafiltrate and the withdrawn blood into the vascular system, and infusing insulin into the patient based on the determined level of glucose.
