Patent number: 9134316Abstract: A fluid sensor comprises a formed plastic body and a reagent. The body has a top face with an integral first surface. The body also has a bottom face opposed to the first surface and a sidewall that extends from the periphery of the top face. The first surface is adapted to accept a fluid sample. The reagent is disposed on the integral first surface and causes a color change detectable on the bottom face when the reagent reacts with an analyte in the fluid sample.Type: GrantFiled: March 10, 2014Date of Patent: September 15, 2015Assignee: Bayer HealthCare LLCInventors: Sung-Kwon Jung, Steven C.

Patent number: 8981284Abstract: A method of determining auto-calibrating information of a test sensor includes providing an optical read head that includes a light source, a light guide and a detector. The read head forms an opening that is sized to receive a test sensor. The detector includes a linear-detector array or single detector. A test sensor is provided having apertures formed therein. The test sensor is placed in the opening of the optical read head. Light is transmitted from the light source through the apertures. The light transmitted through the apertures using the detector or detecting the absence of light being transmitted through the test sensor using the detector is detected. The detected light or the absence of detected light information from the detector is used to determine the auto-calibration information of the test sensor.Type: GrantFiled: April 9, 2014Date of Patent: March 17, 2015Assignee: Bayer HealthCare LLCInventors: Russell J. Micinski, Andrew J. Dosmann, Steven C. Charlton

Patent number: 8398567Abstract: An apparatus and method for analyzing an analyte in a body fluid sample using a lancing device (10) having a hollow lancet are disclosed. According to one embodiment of the present invention, the method comprises the acts of lancing the skin of a test subject with the hollow lancet (18) having an interior of the hollow lancet (18) that forms a capillary channel, collecting a body fluid sample from the lanced skin in the capillary channel of the hollow lancet (18), and analyzing the body fluid sample for determining the analyte concentration in the body fluid sample while the collected body fluid sample remains in the lancet (18).Type: GrantFiled: February 4, 2005Date of Patent: March 19, 2013Assignee: Bayer HealthCare LLCInventors: Rex J.

Patent number: 8377381Abstract: An optical waveguiding optical format enables consistent optical analysis of small sample volumes. The optical format is comprised of an illumination light guide, a read window upon which a sample is placed, a sample collection needle or capillary, and a detection guide. Light redirecting facets are provided within the format itself such that the format serves as a unitary component for accepting light, directing light through a sample, and emitting light for detection.Type: GrantFiled: January 2, 2004Date of Patent: February 19, 2013Assignee: Bayer HealthCare LLCInventors: Andrew J.

Patent number: 8226904Abstract: Formats for optical analysis of fluid samples are provided with platforms and wells for contacting fluid samples and bringing reagents in contact with fluid samples. Formats may be made in opposing platform-and-well constructions, allowing a platform protruding from one format member to enter a well contained within an opposing format member. A sample fill nose accepts sample fluid from a sample collection opening and transports the sample fluid through the format.Type: GrantFiled: October 29, 2004Date of Patent: July 24, 2012Assignee: Bayer Healthcare LLCInventor: Andrew J.

Patent number: 8184273Abstract: A total transmission spectroscopy system for use in determining the analyte concentration in a fluid sample comprises a sample cell receiving area, a light source, a collimating lens, a first lens, a second lens, and a detector. The sample cell receiving area is adapted to receive a sample to be analyzed. The sample cell receiving area is constructed of a substantially optically clear material. The collimating lens is adapted to receive light from the light source and adapted to illuminate the sample cell receiving area with a substantially collimated beam of light. The first lens is adapted to receive regular and scattered light transmitted through the sample at a first angle of divergence. The first lens receives light having a first angle of acceptance. The first lens outputs light having a second angle of divergence. The second angle of divergence is less than the first angle of divergence.Type: GrantFiled: January 10, 2011Date of Patent: May 22, 2012Assignee: Bayer Healthcare LLCInventors: Andrew J.
