Extracorporeal Blood Processing Information Management System

US Patent:
7072769, Jul 4, 2006
Filed:
Mar 1, 2001
Appl. No.:
09/797325
Inventors:
Peter Fletcher-Haynes - Bailey CO, US
William Sweat - Lakewood CO, US
Richard Judy - Littleton CO, US
Scott Butzke - Littleton CO, US
Kim Pemberton - Greenwood Village CO, US
Frank Corbin, III - Littleton CO, US
Robert W. Langley - Westminster CO, US
Steven Gage Urdahl - Golden CO, US
Christopher Fletcher - Superior CO, US
Assignee:
Gambro, Inc. - Lakewood CO
International Classification:
G01N 33/48
G01N 33/50
US Classification:
702 21, 702 30, 702 31, 702 32
Abstract:
A blood component collection system with manipulation and optimization capabilities. In one embodiment, process parameters are derived from an input/configured predetermined blood component yield and which is based upon the maximization of at least one process parameter. Thereafter, the blood component collection procedure is performed with these derived process control parameters. In another embodiment, process parameters are derived from an input total procedure time from a maximized value for at least one of the other process control parameters so as to maximize blood component yield in this fixed time. Thereafter, the blood component collection procedure is performed with these derived parameters.

Blood Processing Apparatus With Incipient Spill-Over Detection

US Patent:
7828709, Nov 9, 2010
Filed:
Sep 30, 2008
Appl. No.:
12/241846
Inventors:
William Sweat - Lakewood CO, US
Assignee:
CaridianBCT, Inc. - Lakewood CO
International Classification:
B01D 21/26
US Classification:
494 37, 494 10, 210745
Abstract:
A density centrifuge blood processing system comprising a separation chamber rotating about a central rotation axis, the separation chamber being coupled to an elutriation chamber, a first detector for the separation chamber to detect light from an observation region, a computational apparatus distinguishing at least two regions in the observation region and distinguishing incipient spill over of cellular components out of the elutriation chamber as a function of light intensity received from the at least two regions in the separation chamber, and a controller regulating speed of at least one pump or of the separation chamber in response to signals from the computational apparatus to avoid spill over.

Blood Processing Apparatus With Optical Reference Control

US Patent:
7951059, May 31, 2011
Filed:
Sep 18, 2008
Appl. No.:
12/233185
Inventors:
William Sweat - Lakewood CO, US
Assignee:
CaridianBCT, Inc. - Lakewood CO
International Classification:
B04B 15/00
US Classification:
494 10, 494 37
Abstract:
A density centrifuge blood processing system with automatic two-dimensional optical control of fluid separation by observing fluid characteristics in observation regions. The location of the regions is determined by monitoring an optical reference. Points representing edges of an optical reference are measured and lines are computed through the points. An error measurement is calculated for each line. If the error is too large, the image is abandoned. One of the lines is selected as a referent line. A new line is calculated orthogonal to the referent line. The error function is again computed for the dependant line. If the error exceeds a selected maximum, the frame is discarded. A transformation function translates data points from an (r, s) domain derived from measurements of the edges into an (x, y) domain used to identify pixels in the observation areas.

Blood Processing Apparatus With Incipient Spill-Over Detection

US Patent:
8062202, Nov 22, 2011
Filed:
Oct 7, 2010
Appl. No.:
12/899791
Inventors:
William Sweat - Lakewood CO, US
Assignee:
CaridianBCT, Inc. - Lakewood CO
International Classification:
B04B 13/00
US Classification:
494 7, 494 37, 210745
Abstract:
A density centrifuge blood processing system comprising a separation chamber rotating about a central rotation axis, the separation chamber being coupled to an elutriation chamber, a first detector for the separation chamber to detect light from an observation region, a computational apparatus distinguishing at least two regions in the observation region and distinguishing incipient spill over of cellular components out of the elutriation chamber as a function of light intensity received from the at least two regions in the separation chamber, and a controller regulating speed of at least one pump or of the separation chamber in response to signals from the computational apparatus to avoid spill over.

Blood Processing Apparatus With Controlled Cell Capture Chamber Trigger

US Patent:
8066888, Nov 29, 2011
Filed:
Sep 26, 2008
Appl. No.:
12/238697
Inventors:
William Sweat - Lakewood CO, US
Jeremy Kolenbrander - Brighton CO, US
John R. Lindner - Morrison CO, US
Jennifer Hinz - Thornton CO, US
Assignee:
CaridianBCT, Inc. - Lakewood CO
International Classification:
B01D 21/32
US Classification:
210745, 210787, 210 87, 494 2, 494 7, 494 20, 494 37
Abstract:
A blood cell collection system having means for detecting when a cell separation chamber has filled with white blood cells, and flushing the cells out of the cell separation chamber into a collect bag. A red-green sensor senses the optical characteristics of fluid leaving the cell separation chamber. A baseline value is calculated. The device calculates a ratio of the intensities of red light and green light and a peak-to-peak ratio of intensities. If either ratio exceeds thresholds computed from the baseline, the device flushes the cells into the collect bag. A camera detects white cells passing into the cell separation chamber and the device calculates the number of cells being collected. If the calculated number of collected cells exceeds a certain limit, the cell separation chamber is flushed. If the device is unable to establish a baseline, the donation can proceed, relying solely on the calculated number of collected cells.

Blood Processing Apparatus With Optical Reference Control

US Patent:
8070663, Dec 6, 2011
Filed:
Apr 22, 2011
Appl. No.:
13/092639
Inventors:
William Sweat - Lakewood CO, US
Assignee:
CaridianBCT, Inc. - Lakewood CO
International Classification:
B04B 15/00
US Classification:
494 10, 494 43, 210 91, 210745
Abstract:
A density centrifuge blood processing system with automatic two-dimensional optical control of fluid separation by observing fluid characteristics in observation regions. The location of the regions is determined by monitoring an optical reference. Points representing edges of an optical reference are measured and lines are computed through the points. An error measurement is calculated for each line. If the error is too large, the image is abandoned. One of the lines is selected as a referent line. A new line is calculated orthogonal to the referent line. The error function is again computed for the dependant line. If the error exceeds a selected maximum, the frame is discarded. A transformation function translates data points from an (r, s) domain derived from measurements of the edges into an (x, y) domain used to identify pixels in the observation areas.

Blood Processing Apparatus With Robust Automated Process Control

US Patent:
8337379, Dec 25, 2012
Filed:
Jul 2, 2007
Appl. No.:
11/772692
Inventors:
Christopher Fletcher - Boulder CO, US
William Sweat - Lakewood CO, US
Jeremy Kolenbrander - Brighton CO, US
Aditya Dalvi - Golden CO, US
John R. Linder - Morrison CO, US
Assignee:
Terumo BCT, Inc. - Lakewood CO
International Classification:
B04B 9/10
B04B 13/00
A61M 37/00
US Classification:
494 7, 210 94, 2105121, 210782, 356 39, 494 1, 494 10, 494 37, 494 45, 604 604
Abstract:
A centrifuge for separating blood having a camera observing fluid flow, and a controller controlling the flow. The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity, or. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct.
