  • Optical access disconnection systems and methods
    Patent number: 8376978
    Abstract: An access disconnection system includes: a material capable of absorbing blood from a patient upon an arterial or venous line disconnection; a light emitter positioned to emit light onto the material; a light receiver positioned to receive light reflected off of the material; and electronic circuitry operably coupled to at least one of the light emitter and receiver, the circuitry configured to provide an output (i) when light received by the receiver reaches a particular level or (ii) indicative of an amount of light received by the light receiver.
    Type: Grant
    Filed: February 9, 2007
    Date of Patent: February 19, 2013
    Assignees: Baxter International Inc., Baxter Healthcare S.A.
    Inventors: Rodolfo G. Roger, Joel Tejedor, Robert W. Childers
  • Adaptive algorithm for access disconnect detection
    Patent number: 7938792
    Abstract: An extracorporeal therapy machine removes blood from a patient in order to treat the blood and then return the blood to the patient. If the removal needle or the return needle is dislodged and blood is not returned, the patient may suffer a great blood loss. A new technique for detecting dislodgement uses the normal, initial values of a plurality of parameters of the patient and the therapy machine to set criteria or limits for an alarm, and then adjusts those criteria based on the later values of those parameters as they change during one therapy or over several therapies experienced by the patient.
