Methods And Apparatus For Sampling And Analyzing Body Fluid
view source
US Patent:

6352514, Mar 5, 2002
Filed:

Apr 19, 2000
Appl. No.:

09/552243
Inventors:

Joel S. Douglas - Santa Clara CA
Jeffrey N. Roe - San Ramon CA
Ryszard Radwanski - Morgan Hill CA
Brent G. Duchon - San Jose CA
Assignee:

Amira Medical - Scotts Valley CA
International Classification:

A61B 500
US Classification:

600583, 600584, 606181
Abstract:

A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.

US Patent:

6464649, Oct 15, 2002
Filed:

Mar 31, 2000
Appl. No.:

09/542040
Inventors:

Brent G. Duchon - San Jose CA
Jeffrey N. Roe - San Ramon CA
Ryszard Radwanski - Morgan Hill CA
Joel S. Douglas - Santa Clara CA
Assignee:

Amira Medical - Scotts Valley CA
International Classification:

A61B 500
US Classification:

600583, 606181
Abstract:

Body fluid is sampled from a skin incision by placing a ring against the skin and repeatedly applying an elastic pressing force to the ring, whereby a stimulator surface of the ring depresses a ring of skin and body tissue in surrounding relationship to the incision to force body fluid from the incision. The stimulator surface is inclined at an angle of 10 to 65 degrees; a width of the stimulator surface is from 5 mm to 20 mm, and an inner diameter of the stimulator surface is no less than 6. 0 mm.

US Patent:

6750962, Jun 15, 2004
Filed:

Apr 10, 2001
Appl. No.:

09/828874
Inventors:

Joel S. Douglas - Los Altos Hills CA
Jeffrey N. Roe - San Ramon CA
John H. Priest - Everett WA
John M. Gleisner - Lynnwood WA
Charles C. Raney - Scotts Valley CA
David A. Hasker - San Jose CA
Ryszard Radwanski - Morgan Hill CA
John Ramirez - Sunnyvale CA
Assignee:

Amira Medical - Scotts Valley CA
International Classification:

G01N 110
US Classification:

356246, 356440
Abstract:

A multi-use assay system accurately docks a removable test strip supporting a reagent-analyte reaction with an optics system including an LED, photodetector, and lenses or light pipes for directing light to and from the test strip. Docking is achieved using alignment fixturing, whereby an optics block holder is relied upon to align the test strip and test pad with the various optical components. Signals from the photodetector indicative of test strip reaction progress are provided to a processor for measuring the analyte.

Assignee:

Roche Diagnostics Operations, Inc. - Indianapolis IN
International Classification:

G01N 33543
US Classification:

436518, 422 55, 422 56, 422 57, 422 58, 435 4, 4352871, 4352872, 4352877, 4352878, 4352879, 435805, 435810, 435970, 436164, 436169, 436170, 436530, 436805, 436810
Abstract:

A method of making strip for testing for the presence of an analyte generally comprises providing a support member which includes a spreading layer and a reagent layer, and a capillary in communication with the support layer and spreading layer for transporting a sample of body fluid thereto.

US Patent:

6793633, Sep 21, 2004
Filed:

Nov 20, 2001
Appl. No.:

09/988799
Inventors:

Joel S. Douglas - Los Altos Hills CA
Jeffrey N. Roe - San Ramon CA
Ryszard Radwanski - Morgan Hill CA
Henry M. Grage - Danville CA
Michael S. Sanchez - Mountain View CA
Assignee:

Roche Diagnostics Operations, Inc. - Indianapolis IN
International Classification:

A61B 500
US Classification:

600583
Abstract:

A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle ( ), drive mechanism ( ), kneading or vibration mechanism ( ), optional suction system ( ), and sample ejection mechanism. The device is preferably sized to be hand-held in one hand and operable with one hand. The device can optionally contain integral testing or analysis component ( ) for receiving the sample and providing testing or analysis indication or readout for the user. A method involves piercing the skin at a rapid rate, kneading the surrounding area by ultrasonic action, piezoelectric or mechanical oscillation to stimulate the blood flow from the wound, drawing the fluid using a pumping system.

US Patent:

7235056, Jun 26, 2007
Filed:

Apr 23, 2002
Appl. No.:

10/128780
Inventors:

Brent G. Duchon - San Jose CA, US
Joel S. Douglas - Los Altos Hills CA, US
Jeffrey N. Roe - San Ramon CA, US
Ryszard Radwanski - Morgan Hill CA, US
Andrew M. Drexler - Los Altos Hills CA, US
Assignee:

Amira Medical - Palo Alto CA
International Classification:

A61B 5/00
US Classification:

600583, 600584, 606181
Abstract:

A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.
