International Classification:

A61B 500

US Classification:

600316, 600310, 600365

Abstract:

A method calibrates a monitor that comprises a non-invasive blood constituent monitor and a traditional measurement system. The non-invasive blood constituent monitor includes a thermal gradient inducing element an analyzer window. A traditional monitor output representing a property of a blood constituent is generated by the traditional measurement system. A non-invasive monitor output representing the property of the whole blood constituent is generated by the non-invasive constituent monitor. The traditional monitor output and the non-invasive monitor output are compared to estimate an amount of error. The non-invasive monitor output is corrected by the amount of error.

International Classification:

G01J001/10

US Classification:

356/243500

Abstract:

In accordance with one embodiment there is provided a method of providing a known spectrum to a noninvasive optical detection system of the type having a window for receiving infrared energy. The method comprises affixing a standard to the window. The standard comprises a body formed from a material having known and stable spectral properties. The method further comprises placing at least a portion of the body directly against the window, and operating the optical detection system to detect an emission spectrum of the body. In accordance with another embodiment an infrared spectrometer comprises a window for receiving infrared energy. The window has an exposed surface. The infrared spectrometer further comprises a standard comprising a body formed of a material having known and stable spectral properties. At least part of the body is removably disposed directly against the exposed surface of the window.

International Classification:

C12Q001/54
G01F001/64
G01N027/26
G01N033/50

US Classification:

435/014000, 205/777500

Abstract:

Herein is described a system that includes a processing circuit for identifying possible zone D errors among estimated blood glucose concentration values. The system converts estimated blood glucose concentration values which are identified as possible zone D errors into adjusted blood glucose concentration values which are lower in blood glucose concentration magnitude than their corresponding estimated blood glucose concentration values, thereby decreasing the occurrence of zone D errors. Herein is also disclosed a method for improving the clinical accuracy of an analyte concentration measurement. One method includes a first act of computing an estimated analyte concentration having an associated first error that is clinically significant and a second act of processing the estimated analyte concentration to generate an adjusted analyte concentration having a second error that is clinically insignificant.

International Classification:

A61B 5/00

US Classification:

600584000

Abstract:

Disclosed is a sample element for holding a volume of bodily fluid drawn from the skin of a patient at a withdrawal site. The sample element comprises a housing defining a sample chamber therein, and a barrier. The sample element also comprises a vacuum source. The barrier has a first side configured to contact the skin of the patient at the withdrawal site, and a second side in fluid communication with the sample chamber. The barrier is configured to be pierced by a lance to permit the bodily fluid to pass from the first side to the second side. Additionally, the vacuum source can be actuated to draw the bodily fluid through the barrier and into the sample chamber. Also disclosed is a method of drawing a bodily fluid form the skin of a patient at a withdrawal site. The method comprises placing a first side of a barrier against the skin of the patient at the withdrawal site. The method further comprises forming a first opening through the barrier and a second opening in the skin of the patient at the withdrawal site. The first and second openings are in fluid communication. The method further comprises applying suction at the first opening of the barrier to draw a bodily fluid from the patient.
