  • Patent number: 9262586
    Abstract: A method of enhancing readability of a graph showing glucose values received from a continuous glucose monitoring device (CGM) on the display of a handheld device includes receiving a plurality of CGM glucose values separated by a first fixed time interval. A second fixed time interval at which to display at least a portion of the plurality of CGM glucose values is received. The second fixed time interval is greater than the first fixed time interval. A computer processor of the handheld device determines a characteristic CGM glucose value at a preselected fixed time for each of a sequence of second fixed time intervals within a patient-specified time period. Each characteristic CGM glucose value is derived from two or more received CGM values centered about the preselected fixed time in the corresponding second fixed time interval. The characteristic CGM glucose values for a patient-selected period of time on the display.

  • Patent number: 9216001
    Abstract: The presence of a cardiac pulse in a patient is determined by evaluating physiological signals in the patient. In one embodiment, a medical device evaluates optical characteristics of light transmitted into a patient to ascertain physiological signals, such as pulsatile changes in general blood volume proximate a light detector module. Using these features, the medical device determines whether a cardiac pulse is present in the patient. The medical device may also be configured to report whether the patient is in a VF, VT, asystole, or PEA condition, in addition to being in a pulseless condition, and prompt different therapies, such as chest compressions, rescue breathing, defibrillation, and PEA-specific electrotherapy, depending on the analysis of the physiological signals. Auto-capture of a cardiac pulse using pacing stimuli is further provided.

  • Patent number: 9192338
    Abstract: 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).

  • Patent number: 9192329
    Abstract: A user configurable variable mode pulse indicator provides a user the ability to influence outputs indicative of a pulse occurrence at least during distortion, or high-noise events. For example, when configured to provide or trigger pulse indication outputs, a pulse indicator designates the occurrence of each pulse in a pulse oximeter-derived photo-plethysmograph waveform, through waveform analysis or some statistical measure of the pulse rate, such as an averaged pulse rate. When the configured to block outputs or not trigger pulse indication outputs, a pulse indicator disables the output for one or more of an audio or visual pulse occurrence indication. The outputs can be used to initiate an audible tone “beep” or a visual pulse indication on a display, such as a vertical spike on a horizontal trace or a corresponding indication on a bar display. The amplitude output is used to indicate data integrity and corresponding confidence in the computed values of saturation and pulse rate.

  • Patent number: 9161700
    Abstract: The present invention provides a technique for continuous measurement of blood pressure based on pulse transit time and which does not require any external calibration. This technique, referred to herein as the ‘Composite Method’, is carried out with a body-worn monitor that measures blood pressure and other vital signs, and wirelessly transmits them to a remote monitor. A network of body-worn sensors, typically placed on the patient's right arm and chest, connect to the body-worn monitor and measure time-dependent ECG, PPG, accelerometer, and pressure waveforms. The disposable sensors can include a cuff that features an inflatable bladder coupled to a pressure sensor, three or more electrical sensors (e.g. electrodes), three or more accelerometers, a temperature sensor, and an optical sensor (e.g., a light source and photodiode) attached to the patient's thumb.
