US Patent:

6679841, Jan 20, 2004

Filed:

Jun 15, 2001

Appl. No.:

09/880948

Inventors:

Peter M. Bojan - Grayslake IL
Timothy P. Henning - Vernon Hills IL
Neil W. Loomis - Racine WI
Mark R. Pope - Grayslake IL
Jonathan A. Eppstein - Atlanta GA

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61B 500

US Classification:

600309, 600310, 600345, 600584

Abstract:

An article capable of both collecting interstitial fluid and detecting an analyte in that fluid and a method for use of that article. Preferably, the article is also capable of measuring the amount of analyte in the interstitial fluid. The article can be used in conjunction with a meter that contains an appropriate detection element for determining the amount of analyte in the interstitial fluid. In one preferred embodiment, the article is a multiple-layer element comprising: (1) a layer that is capable of being placed in contact with the skin of a patient; (2) a layer that is coated over the skin-contacting layer; (3) a layer, substantially coplanar with the overcoat layer, that is capable of transporting interstitial fluid by means of chemically aided wicking; (4) a layer, overlying the interstitial fluid transporting layer, that is capable of being placed in contact with a meter, said layer having an opening therein through which light can be transmitted; (5) a layer, disposed on the surface of the meter-contacting layer that faces the skin-contyacting layer, that is capable of detecting the presence of analyte or measuring the amount of analyte in the fluid. In order to use the multiple-layer element, light from a source of light is transmitted through the opening in the multiple-layer material to be absorbed at a light-absorbing target on the skin-contacting layer. This light transfers energy to the target, and this transferred energy causes an opening to form in the skin-contacting layer and an opening to form in the stratum corneum.

International Classification:

C12Q 3/00

US Classification:

435 3, 435 33, 4352864, 4352871, 4352873

Abstract:

A method and apparatus for running a plurality of tests concurrently to obtain data relating to the electrophysiological properties of receptors and channels in biological membranes of test subjects, such as, for example, oocytes. The invention further provides software for controlling, acquiring, and recording data relating to electrophysiological properties of receptors and channels in biological membranes of test subjects, such as, for example, oocytes. This invention increases the throughput rate for experiments and assays employing receptors and ion channels expressed in biological membranes of test subjects, such as, for example, oocytes. In the case of an oocyte, these receptors and channels may be natively expressed (endogenous), may be placed into the oocyte (exogenous), or may be expressed from other RNA or DNA previously placed into the oocyte (exogenous). The invention provides a means for a sole researcher to operate a plurality of electrophysiological test stations in the time and space conventionally required by a single electrophysiological test station. The invention automates these stations and provides a means for a sole individual to perform large sets of experiments that would be physically and mentally exhausting in the absence of this invention.

US Patent:

Filed:

Dec 31, 2009

Appl. No.:

12/650693

Inventors:

Zhengyan Wang - Antioch IL, US
Surya Pratap Rai - Round Lake IL, US
Peter Bojan - Grayslake IL, US
David G. Zabel - Hoffman Estates IL, US
Joseph Allen Carmichael - Burlington WI, US
Ralph LaBedz - McHenry IL, US

Assignee:

Baxter International, Inc. - Deerfield IL
Baxter Healthcare S.A. - Glattpark (Opfikon)

International Classification:

F04B 43/12
F04B 49/06

US Classification:

417 53, 417474, 417479, 604153

Abstract:

An infusion pump uses an improved shuttle mechanism to more reliably pump liquids in low volumes for medical and other purposes. The improved shuttle uses linear translation and wider, symmetric jaws to grasp infusate tubing and pump liquid infusate through the tubing. Adjustment of the linear motion allows a user to also adjust a pumping volume of the infusion pump. Other shuttles with wider jaws may also pump infusate using a rotary motion. In addition, more than one shuttle, such as two or three shuttles, may be used to approximate continuous pumping. A series of several smaller linear shuttles with sequential actuation may be used as a linear peristaltic pump for general peristaltic pump applications.

US Patent:

Filed:

Jun 29, 2010

Appl. No.:

12/826192

Inventors:

Peter M. Bojan - Grayslake IL, US
Zhengyan Wang - Antioch IL, US
Surya Rai - Lake Bluff IL, US
Paul Olczak - Evanston IL, US

Assignee:

Baxter International Inc. - Deerfield IL
Baxter Healthcare S.A. - Glattpark (Opfikon)

International Classification:

G01M 3/02

US Classification:

73 37

Abstract:

An infusion pump uses sensors, movable members and a control unit to determine tubing thickness in a tube-loading section of the pump. The infusion pump utilizes sensors, such as a pressure sensor, to record forces imparted by a tube undergoing no pressure, a single pressure, or a pressure sweep, to determine thickness. Using these values, the tubing wall thickness can be determined. The infusion pump can also compress a tube using a movable member of the pump and records the distance traveled by the movable member to compress fully the tube. Using this distance, the tubing wall thickness can be determined.

US Classification:

604250000

Abstract:

A system and method for automatically delivering an infusate to a patient is disclosed. The system includes an infusion set and an infusion device. A signaling component disposed on an infusion set component identifies an administration protocol for the infusion set. A detection device operatively connected to the infusion device detects the signaling component and identifies the administration protocol. The infusion device is then configured to operate according to the administration protocol.

Andrew J. Muetterties - Mundelein IL

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61B 1818

US Classification:

606 9

Abstract:

A method for increasing the permeability of the stratum corneum by means of a source of light, preferably a laser, more preferably a pulsed laser. By increasing the permeability of the stratum corneum, access to the interstitial fluid is achieved, thereby enabling measurement of analytes in the interstitial fluid. In one aspect, the method comprises the steps of: (a) providing a source of light having a wavelength of from about 930 nm to about 1040 nm; and (b) exposing a region of the stratum corneum of the patient to said source of light for a period of time sufficient to form an opening in the stratum corneum. Preferably, exposure of the region of the stratum corneum to the source of light is ceased when an amount of interstitial fluid fills the opening in the stratum corneum, which amount is sufficient to cause the scatter intensity of the light reflected from the surface of the interstitial fluid occupying the opening in the stratum corneum to differ from the scatter intensity of the light reflected from a region of the stratum corneum that is substantially free of interstitial fluid. The invention also involves an apparatus for carrying out the foregoing method.
