US Patent:

8366316, Feb 5, 2013

Filed:

Mar 23, 2010

Appl. No.:

12/730197

Inventors:

Dean Kamen - Bedford MA, US
N. Christopher Perry - Manchester NH, US
Jason A. Demers - Manchester NH, US
Brian Tracey - Litchfield NH, US

Assignee:

DEKA Products Limited Partnership - Manchester NH

International Classification:

G01N 25/18

US Classification:

374 44

Abstract:

A sensor apparatus and sensor apparatus system for use in conjunction with a cassette, including a disposable or replaceable cassette. In some embodiments, the cassette includes a thermal well for permitting the sensing of various properties of a subject media. The thermal well includes a hollow housing of a thermally conductive material. In other embodiments, the cassette includes sensor leads for sensing of various properties of a subject media. The thermal well has an inner surface shaped so as to form a mating relationship with a sensing probe. The mating thermally couples the inner surface with a sensing probe. In some embodiments, the thermal well is located on a disposable portion and the sensing probe on a reusable portion.

US Classification:

73290 R, 210636, 210647, 715764

Abstract:

Dialysis systems comprising actuators that cooperate to perform dialysis functions and sensors that cooperate to monitor dialysis functions are disclosed. According to one aspect, such a hemodialysis system comprises a user interface model layer, a therapy layer, below the user interface model layer, and a machine layer below the therapy layer. The user interface model layer is configured to manage the state of a graphical user interface and receive inputs from a graphical user interface. The therapy layer is configured to run state machines that generate therapy commands based at least in part on the inputs from the graphical user interface. The machine layer is configured to provide commands for the actuators based on the therapy commands.
