The commonly used glucose monitors, which we usually just call “glucose meters” give a one-time measurement of blood sugar by using a drop of blood obtained by pricking your skin and applied to a single-use test strip. This is what the vast majority of people with diabetes use to monitor their blood sugar levels.

Active pulse blood constituent monitoring
InactiveUS6931268B1Ability to determinePreventing any perturbationDiagnostic recording/measuringSensorsBlood volume pulseNon invasive
A blood glucose monitoring system is disclosed which provides for inducing an active pulse in the blood volume of a patient. The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio. This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system. Radiation which passes through the fleshy medium is detected by a detector which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.

ActiveUS7822452B2Diagnostic signal processingSensorsDifference-map algorithmBlood Glucose Measurement
The present invention relates to a method for estimating blood glucose levels using a noninvasive optical coherence tomography- (OCT-) based blood glucose monitor. An algorithm correlates OCT-based estimated blood glucose data with actual blood glucose data determined by invasive methods. OCT-based data is fit to the obtained blood glucose measurements to achieve the best correlation. Once the algorithm has generated sets of estimated blood glucose levels, it may refine the number of sets by applying one or more mathematical filters. The OCT-based blood glucose monitor is calibrated using an Intensity Difference plot or the Pearson Product Moment Correlation method.

Method to determine the degree and stability of blood glucose control in patients with diabetes mellitus via the creation and continuous update of new statistical indicators in blood glucose monitors or free standing computers
InactiveUS20070010950A1Increase contributionShorten the timeDiagnostic recording/measuringSensorsInstabilityGlucose control
Microvascular complications of diabetes mellitus are closely related to blood glucose levels and fluctuations. The Glycostator statistical package was created to allow patients and health care providers simple access to “glycemic indicators” which permit a “snapshot view” of the effectiveness of the patient's diabetes management program. Glycostator functions provide a simple way of enhancing the information already provided by home blood glucose monitoring devices. To this end, a set of new indices, including one called the Virtual A1c, are computed in a recursive fashion from blood glucose test results to provide a more meaningful day-to-day assessment of glycemic control. All indices can be made available at the meter user interface on request. The displayed indices allow patients to improve glycemic control by identifying problems with blood glucose control and lability that are less easily recognized in traditional blood glucose meter statistical packages. Virtual A1c emulates hemoglobin A1c continuously and provides better day-to-day assessment of long term glycemic control than does the traditional average blood glucose report. The method for computing each of these indices, including the Virtual A1c, allows for their implementation in commercial blood glucose monitors.

Remote health monitoring and maintenance system
A system and method is described that enables a health care provider to monitor and manage a health condition of a patient. The system includes a health care provider apparatus operated by a health care provider and a remotely programmable patient apparatus that is operated by a patient. The health care provider develops a script program using the health care provider apparatus and then sends the script program to a remotely programmable patient apparatus through a communication network such as the World Wide Web. The script program is a computer-executable patient protocol that provides information to the patient about the patient's health condition and that interactively monitors the patient health condition by asking the patient questions and by receiving answers to those questions. The answers to these health related questions are then forwarded as patient data from the remotely programmable patient apparatus to the health care provider apparatus through the communication network. The patient data may also include information supplied by a physiological monitoring device such as a blood glucose monitor that is connected to the remotely programmable patient apparatus. When the patient data arrives at the health care provider apparatus, the patient data is processed for further management of the patient's health condition by the health care provider, such as forwarding another script program to the remotely programmable patient apparatus.

A portable insulin injection pen and blood glucose monitoring device is integrated into a single unit for testing and treating diabetes symptoms. The device has a housing of a size suitable for transport in a user's clothing pocket or handbag. Within the housing is a blood glucose monitoring system for receiving a sample of the user's blood and detecting its glucose level, an insulin injection mechanism for administering an insulin injection, and a microprocessor that calculates an insulin dosage appropriate to the detected blood glucose level and sets the insulin injection mechanism to administer the calculated insulin dosage. A communication device automatically informs a remote emergency service provider, such as 911 or an emergency service to which the user has subscribed, if the microprocessor determines that the detected blood glucose level presents a potential danger to the user. The microprocessor also calculates treatment regimens specific to a particular user based on the detected blood glucose level and displays the treatment regimens on an LCD display. In a particularly advantageous embodiment, a GPS receiver within the housing detects the location of the device, and the communication device, which can be a cellular telephone separate from the housing connected wirelessly to the unit via a Bluetooth connection or cellular telephone circuitry within the housing itself, transmits information regarding the location to the remote emergency service.
