7552655, Jun 30, 2009

Filed:

Dec 4, 2007

Appl. No.:

11/999316

Inventors:

Normand Nantel - San Carlos CA, US
Adrian Smith - Emerald Hills CA, US
Scot Cheu - San Jose CA, US
Derrick J. Parks - Belmont CA, US
Jamshed Ghandhi - San Carlos CA, US

Assignee:

Novartis Pharma AG - Basel

International Classification:

G01G 9/00

US Classification:

73865

Abstract:

The invention provides systems and methods for measuring the mass of a substance. In one method, energy is applied to a substance and a response resulting from the application of energy as measured. The mass of the substance is then determined based at least in part on the measured response.

Assignee:

Becton Dickinson and Company - Franklin Lakes NJ

International Classification:

C08F 246
C08J 718
H05H 100

US Classification:

427488

Abstract:

The present invention is a non-ideal barrier coating composition and the method for applying the coating composition to substrates. The non-ideal barrier coating is useful for providing an effective barrier against gas permeability in containers and for extending shelf-life of containers, especially plastic evacuated blood collection devices.

Filed:

Sep 30, 1996

Appl. No.:

8/724516

Inventors:

Jamshed B. Ghandhi - Carrboro NC

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

G01N 1508

US Classification:

73 40

Abstract:

The present invention is directed to a method for measuring the shelf life of vacuum actuated tubes for blood sample collection, wherein the method comprises placing a collection tube in an apparatus having a first and a second sealable chamber, pressurizing the apparatus to a value above ambient pressure, and sealing both chambers such that each chamber has an identical pressure and is isolated from the other chamber. Leakage of gas into the collection tube located in the first chamber is detected as a differential pressure change relative to the second chamber. This change in pressure is recorded and is indicative of the rate of gas transport into the collection tube.

Inventors:

Jamshed B. Ghandhi - Carrboro NC

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

G01N 1508

US Classification:

73 40

Abstract:

The present invention is directed to an apparatus for measuring gas permeation through test articles, such as evacuated tubes used for blood sample collection. The apparatus includes first and second sealable chambers, with the collection tube being placed in the first chamber. The apparatus is pressurized, and both chambers are sealed such that each chamber has an identical pressure and isolated from the other chamber. Permeation of gas into the collection tube located in the first chamber is detected as a differential pressure change relative to the second chamber. This change in pressure is recorded and is indicative of the rate of gas transport into the collection tube.
