Individual calibration of blood glucose for supporting noninvasive self-monitoring blood glucose

A method is provided for calibrating a noninvasive glucose monitor for prospective noninvasive glucose determination. Spectroscopic transflectance readings are measured on the patient's skin using a noninvasive glucose monitor. The patient's blood glucose level is measured with an invasive glucose monitor. The noninvasive and invasive measurements are correlated to form an individual algorithm for each patient. Preferably, the position of the patient's skin with respect to the probe of the noninvasive monitor is spatially adjusted while collecting the transflectance measurements such that multiple readings are taken on the patient's skin. The measurements are preferably taken over a period of time and over a plurality of glucose levels in the patient.

Device for optical monitoring of constituent in tissue or body fluid sample using wavelength modulation spectroscopy, such as for blood glucose levels

A device for monitoring the concentration level of a constituent in tissue or a body fluid sample, such as glucose concentration in blood, has a laser light source which is modulated about a center emission frequency to probe the absorption spectrum of the constituent being monitored, a laser driver circuit for tuning and modulating the laser light, a photodetector for detecting light from the laser light source transmitted through the sample as the modulation frequency of the laser is tuned, and a demodulator for demodulating the transmitted light and detecting variations in magnitude at harmonics of the modulation frequency to assess the concentration level of that constituent. The device utilizes short-wavelength near-infrared laser light to monitor blood glucose levels, and could also be used for drug screening and diagnosis of other medical conditions as well. In one embodiment, the device is used to monitor blood glucose level externally from the body and non-invasively by trans-illumination through a thin layer of skin, without the need for physical penetration of the skin. In another embodiment, the device is used as an intravenous sensor deployed through a catheter, and its output can be used to control an insulin pump to stabilize the patient's blood glucose levels.

System and method for monitoring blood glucose levels using an implantable medical device

T-wave amplitude and QT interval are derived from patient cardiac signals. Then blood glucose levels are determined based on a combination of the T-wave amplitude and the QT interval. By using a combination of both T-wave-based and QT interval-based signals, blood glucose levels can be reliably detected throughout a wide range of blood glucose levels. Once the blood glucose level has been detected, the implanted device compares the blood glucose level against upper and lower acceptable bounds and appropriate warning signals are generated if the level falls outside the bounds. In one example, wherein an implantable insulin pump is additionally provided, the pump is controlled based on the detected blood glucose level to maintain glucose levels within an acceptable range. A calibration technique is also provided for determining patient-specific parameters for use in the detection of blood glucose levels.

Non-or minimally invasive monitoring methods

Methods for detecting the presence or amount of an analyte present beneath a target skin or mucosal surface of an individual are provided. The methods entail disruption of the target skin or mucosal surface, for example using a particle delivery method to provide micro-passages in the tissue. The methods further provide a resealable occlusive dressing or patch for protecting the target site from outside agents as well as maintaining hydration of the sample area. Maintaining hydration over the sampling site allows for continuous diffusion of the analyte of interest from beneath the target site to the target site. Multiple samples over time may then be taken, allowing the user to monitor for the presence of analyte over time. In a preferred embodiment, the methods are used to monitor blood glucose levels. FIG. 1 is a perspective view of resealable, occlusive dressing, with an aperture cover in a closed position.

Assay device, system and method

A system for treating a blood sample (700) having an analyte of interest comprises a strip (200) having a membrane (218), respective portions (216, 220 and 222, or 300) which are provided for receiving the sample, for lysing cells of the sample to liberate hemoglobin, and for capturing glycated hemoglobin. The latter two portions (220 and 222, or 300) of the membrane are treated with lysing and capture agents, respectively. A portion of the strip (214 or 230 or 240) is provided for holding an eluting agent and for releasing the agent upon a release condition. A system for detecting analyte comprises an optical subsystem (550) that is aligned with the strip to provide a signal corresponding to an amount of analyte, and an electronic subsystem (650) for processing the signal (560) to provide a result, such as an amount or percentage of glycated hemoglobin. To use these systems, the user simply applies a small sample (700) to the membrane (218) and closes a door (10) of the detection system over the strip (200) such that the door triggers the release of the eluting agent. No sample pre-treatment is required. The preferably handheld system (100) is a simple and convenient monitoring tool for the user, such as a diabetic patient who must monitor blood glucose on an on-going basis. While the systems are useful in the monitoring of blood glucose, they may be used for treating a sample other than blood and detecting an analyte other than an analyte in blood.

Apparatus and method for monitoring blood glucose levels including convenient display of blood glucose value average and constituent values

A method of presenting glucose data to a person with diabetes from a blood glucose meter is provided in which an effective meal average (EMA) value is presented, followed by two or more of the individual values that make up the EMA, to provide improved feedback data for clinical decisions by patients who need to alter their dose of insulin. The EMA can also comprise a measure of the variability of its constituent values. The EMA encompasses those values that occur at specified times such as 1 hour before and 1 hour after a specified meal time. The EMA is calculated over a limited number of days previous to the calculation (e.g., 3 days) and has a minimum number of values that must be obtained within the time and date ranges. An algorithm allows for exclusion of any given reading from the average (e.g., post-prandial or control solution readings). Patients can use 1 to 8 EMA on any given date range (e.g., preferably 4, that is, breakfast, lunch, supper and bedtime snack).
