Patent number: 8187184Abstract: An optical access disconnect system is useful for detecting the presence of blood. The optical access disconnect system includes one or more optical sensors placed near an access site of a patient, the optical sensors suitable for detecting the presence of blood, especially by detecting a difference in light reflected or absorbed by blood. The optical access disconnect system may also be used as an interlock to assure compliance. A detector may be placed adjacent the access site to detect the access needle, or an object or mark on the access needle or fluid line. A therapy machine, such as a dialysis machine, may be programmed not to start or continue operation unless the needle or fluid line is detected. The detector may be one of the optical sensors, calibrated or adjusted to detect a mark on the needle or access line, or may be another type of detector.Type: GrantFiled: September 21, 2007Date of Patent: May 29, 2012Assignees: Baxter International, Inc., Baxter Healthcare S.A.Inventors: Matthew R.

Patent number: 8114043Abstract: A connection of a patient's vascular system to an extracorporeal blood treatment machine is monitored to ensure the patient's safety during a procedure. The procedure may be hemodialysis, apheresis, plasmapheresis, a coronary by-pass operation, or other procedure. To ensure safe electrical connection, a contact and a return are connected via a conductive connection into the extracorporeal blood circuit. A current is then generated between the contact and the return and is monitored by a non-contact sensor near an access site of the patient. If the current or other quantity related to the current changes significantly, a signal is sent to the machine or a controller to notify a caregiver or a medical professional. The signal may also be sent to immediately stop a blood pump or other component of the machine.Type: GrantFiled: July 25, 2008Date of Patent: February 14, 2012Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventor: Matthew R.

Patent number: 6537445Abstract: A blood processing system comprises a blood separation chamber constructed and arranged for rotation about an axis separate blood into a plasma layer and an adjoining region comprising different first and second cellular blood species arranged in layers according to density. A collection line including a pump removes the plasma layer from the blood separation chamber. The pump operates to control flow through the collection line in response to pump control signals. A sensor assembly in the collection line detects concentration of first and second cellular blood species in the collection line. A controller coupled to the sensor assembly operates to generate the pump control signals according to a selected blood collection protocol. The controller operates, when a first blood collection protocol is selected, to generate a pump control signal when the sensor assembly detects changes in concentration of the first cellular blood species in the collection line.Type: GrantFiled: August 16, 2001Date of Patent: March 25, 2003Assignee: Baxter International Inc.Inventor: Matthew R.
