Abstract: Methods and systems for providing continuous renal replacement therapy (CRRT) to a patient are provided. The system includes a hemofiltration unit that provides continuous venovenous hemofiltration (CVVH), a replacement fluid flow regulator configured to regulate the flow of a replacement fluid, an anticoagulant flow regulator configured to pump an anticoagulant, and a blood warmer. The system provides enhanced access to the extracorporeal circuit for blood analysion, infusion of products and/or anticoagulation control. The system may be used to treat patients having renal insufficiency.

Abstract: A method and apparatus for identifying individuals for the purposes of determining clearance access or surveillance is characterized by enrolling an image of a person's face either voluntarily or secretly to be later used for comparison when the person voluntarily desires clearance or is covertly detected. The system can recognize or identify individuals regardless of whether the individual is wearing eye glasses or attempted disguises. In one embodiment, the system allows an authorized operator to enroll an image of a person through a facial scan for subsequent clearance access. The system records the camera positioning, captures an image, scales the image and records data from a region of interest within the scanned image to a database for later comparison. Enrollment data and the corresponding image information are then associated with a personal identification number assigned to the person.
