Abstract: The invention provides a device for contacting a surface of a patient's body to determine a physiologic parameter in a measurement region of a tissue of the patient. The device typically comprises a sensor responsive to the physiologic parameter and a probe housing the sensor. The probe is constructed to allow the sensor to be secured at a sensing site adjacent to the measurement region, without disturbing the blood flow within the measurement region of the tissue. The device may also include a means for reducing interference in the sensing area. Preferably, the device further comprises an indicating means operably connected to the sensor for indicating an analyte quantity and/or concentration associated with the physiologic parameter.

Abstract: An automatic skin perfusion measuring system including instrumentation that automatically analyzes perfusion measurements to identify motion artifact and SPP values and a sensor placement device is provided. The instrumentation is configured to ignore motion artifact. Perfusion measurements are designated as SPP values if various criteria are met. SPP value criteria pertain to factors including cuff pressure, perfusion, perfusion change percentages relative to previous and subsequent perfusion measurements, and whether perfusion measurements are increasing or decreasing relative to previous and subsequent perfusion measurements. The sensor placement device assures reliable data is produced when multiple measurements are desired.

Abstract: The invention relates to a cartridge for packaging an analyte-containing fluid calibrant. The cartridge is formed from a container having an opening sealed by a sealing member. A septum divides the container into a calibrant compartment and an outer compartment. A probe is provided comprising an analyte-detecting portion and a connecting portion that allows for operative connection to a device for quantitating or determining the concentration of the analyte. The probe may extend sealingly through the septum such that the analyte-detecting portion is located in the calibrant compartment and the connecting portion is located in the outer compartment. The construction of the cartridge provides ease and reduces the likelihood of error in calibrating the probe. The invention also relates to a method of manufacturing the cartridge and a method for calibrating a device for analyte concentration determination and quantitation using the inventive cartridge.
