TECHNICAL FIELD
This application is directed to the field of analyte measurement and more specifically to systems, methods and devices for visualizing analyte measurements, including alerting users of events.
BACKGROUND
Diabetes mellitus is a chronic metabolic disorder caused by an inability of the pancreas to produce sufficient amounts of the hormone insulin, resulting in the decreased ability of the body to metabolize glucose. This failure leads to hyperglycemia, i.e., the presence of an excessive amount of glucose in the blood plasma. Persistent hyperglycemia and/or hypoinsulinemia has been associated with a variety of serious symptoms and life threatening long term complications such as dehydration, ketoacidosis, diabetic coma, cardiovascular diseases, chronic renal failure, retinal damage and nerve damages with the risk of amputation of extremities.
Blood or interstitial glucose monitoring is required to achieve acceptable glycemic control. Continuous glucose monitoring (CGM) has been utilized over the last twenty years for such glucose monitoring. CGM creates data that is much more abundant and complex than that of traditional, episodic glucose monitoring. This added complexity may overwhelm users of the devices, as well as caregivers and health care practitioners (“HCPs”), especially in the absence of a suitable tool to assist in the interpretation of such data.

DETAILED DESCRIPTION
The present disclosure relates to a continuous glucose monitoring system (a “CGM” system) in which an enhanced graphical user interface is provided. Unlike conventional, static user interfaces, the present invention provides animations that better convey and indicate trends in the analyte concentration levels of a user at a minimum. Advantageously, enhanced visualizations, such as animated graphical user interfaces, are a practical enhancement in the field of glucometry that can simplify the communication of information to the user to better facilitate prompt response to events involving an individual.
Conventional systems that provide static reports or centralized reports are not able to meet the real-time needs of a user who is engaged in a treatment plan, e.g., for diabetes mellitus. Advantageously, the present disclosure improves patient outcomes, reduces patient anxiety, and better allows the CGM equipment to perform in a manner that meets the patient's treatment plan. In addition, the present disclosure offers the ability to respond in real-time to potentially dangerous or life-threatening excursions.
Conventional analyte monitoring systems are limited in the ways in which they can display information. Such systems are also static in nature. A large amount of information is available to the system, and simply displaying all the data without synthesis makes it difficult for the user to find useful information. For example, conventional techniques of organizing analyte monitoring data include creating a series of menus that a user must navigate to find information, hampering the utility of such systems. Advantageously, in one aspect, the present disclosure provides a technique for synthesizing large amounts of complex data into actionable, easy to use information, that is delivered at the point of impact to the user. Specifically, by tying together trend data and analyte value data into animations, the present disclosure allows data that was conventionally displayed separately to be unified into a single display to the user, solving the problems identified in conventional systems.
In a CGM system, glucose levels or concentrations can be determined by the use of a continuous glucose monitoring (CGM) sensor. The CGM sensor utilizes, for example, amperometric electrochemical sensor technology to measure glucose with electrodes such as a working electrode and a counter electrode, operably connected to the sensor electronics that are covered by a sensing membrane and a biointerface membrane, which are attached by a clip. Examples of such systems are found, for example, in U.S. Pat. No. 10,188,796 B2 and U.S. Patent Application Publication No. 2018/0296757 A1, each of which are herein incorporated by reference in their entirety.
The top ends of the electrodes are in contact with an electrolyte phase (not shown), which is a free-flowing fluid phase disposed between the sensing membrane and the electrodes. The sensing membrane may include an enzyme, e.g., glucose oxidase, which covers the electrolyte phase. In this exemplary sensor, the counter electrode is provided to balance the current generated by the analyte species being measured at the working electrode. For example, in the case of a glucose oxidase based glucose sensor, the species being measured at the working electrode is H2O2. The current that is produced at the working electrode (and flows through the circuitry to the counter electrode) is proportional to the diffusional flux of H2O2 generated by this electrochemical transformation of glucose into its enzymatic byproducts. Accordingly, a raw signal may be produced that is representative of the concentration of glucose in the user's body, and therefore may be utilized to estimate a meaningful glucose concentration value.
FIG. 1 depicts a system 100 for continuous glucose monitoring of a host 102. The system 100 includes an analyte (e.g., glucose) sensor 112, which transmits analyte concentration level values via wireless transmission 110 to a display unit 104. The display unit 104 could be a custom built unit, a smart phone, a tablet, or any other wirelessly enabled mobile or fixed device that includes a display and at least one processor for receiving and processing data from the analyte sensor 112. In one example, the display unit 104, including the at least one processor thereof, receives, stores, and analyzes data from the analyte sensor 112. For example, the device may be smart phone, e.g., an iPhone available from Apple Inc., of California, and include an ARM microprocessor. In such a case the smart phone may be running an application or app, which performs the functionality of the display unit 104 described herein.
The analyte sensor 112 may be coupled with an electronics module that includes a wireless transceiver for facilitating communication with the display unit 104. In another example, the sensor and transceiver may be part of a combined component. In one embodiment, the display unit 104 may include a touchscreen for input, and may run an operating system for hosting the graphical user interfaces described below. The analyte sensor 112 may be a continuous glucose monitoring sensor of any kind, such as those applied subcutaneously, transdermally, transcutaneously, including but not limited to implantable or other types. The continuous glucose monitoring sensor sends a data stream that includes the level of glucose concentration in the host 102. The display unit 104 is capable of receiving, storing, and processing this data stream. For instance, various algorithms known in the art may run on the at least one processor of the display unit 104 to process the data stream, etc.
It should be understood that the specific glucose analyte measurement examples set forth herein are meant to illustrate a specific implementation and not limit the disclosure in any way. The techniques described herein may be used to visualize continuous analyte measurements for other configurations than that depicted in FIG. 1, e.g., using other sensors for glucose or other analytes found in an interstitial fluid.
FIGS. 2A-23B depict various embodiments of animated graphical user interfaces presented on the display unit 104 of FIG. 1 for visualizing analyte measurements. By way of overview of FIGS. 2A-23B, each pair of figures, such as FIGS. 2A&2B, etc., represent a single exemplary user interface screen with animated visualizations depicted in two different states.
For example, FIGS. 2A & 2B depict a graphical user interface 200 as presented on the display unit. In an upper portion, the graphical user interface 200 includes a colored bubble 202, a white bubble 204, a first trend indicating bubble 206, a second trend indicating bubble 208, and a trend indicating arrow 210.
The color of the colored bubble 202 is configured to change in order to represent whether the current analyte concentration level is above, below, or at the target analyte concentration level as stored by the processor. In some embodiments, a determination that the level is at a target level or range would be based on the level being within a range of values. Levels below the target or target range, as here, are represented by a blue colored bubble, levels above the target analyte concentration level are represented by a red colored bubble, and levels at the target analyte concentration level are represented by a green colored bubble. The white bubble 204, as shown in the herein depicted embodiment, is static and includes near the center of the bubble 204, a current analyte concentration level numerical value. In other embodiments, the concentration level may be depicted using other visual cues, such as by a cluster of dots or objects, a bar of a bar chart embedded in the bubble, a number located in a different portion of the bubble, and the like.
Next and still referring to FIGS. 2A and 2B, the two trend indicating bubbles 206, 208, are disposed beneath the white bubble 204. As may be seen in FIG. 2A, the trend indicating bubble 206 emerges below the white bubble 204, and the second trend indicating bubble 208 emerges above the white bubble 204. As indicated in FIG. 2A, the first and second trend indicating bubbles 206, 208 move upward. In addition to the bubbles 202, 204, 206, 208, the graphical user interface 200 includes an arrow indicator 210, which may include a single arrow, double arrow, blinking arrow(s), and any other directional indicator. In some examples, the arrows may also move to indicate the direction of the trend. In other examples, if animation is turned off, one of the pair bubble images used to show the animation, i.e., FIGS. 2A, 3A, 4A, etc., may appear as static images, and will still serve as a directional indication to the user.
In the graphical user interface 200, trend indication animations are displayed to a user by the graphical user interface 200 periodically oscillating between the state of FIG. 2A and the state of FIG. 2B, with transitions between the states now described. A complete animation of graphical user interface 200 includes the first and second trend indicating bubbles 206208 starting from the position shown in FIG. 2A, each bubble 206, 208 moving upward to the position of FIG. 2B, and then returning downward to the position of FIG. 2A. The upward direction of this movement indicates that the predicted trend of the analyte concentration level is rising. The direction of the arrow indicator 210 in combination with the displayed current analyte concentration level in the white bubble 204 indicates the severity of this rise. For example, an arrow indicator 210 in the upward direction combined with a displayed analyte concentration value of 300 mg/dL indicates a severe glycemic event, while an arrow indicator 210 in the downward direction along with a displayed analyte concentration value of 300 mg/dL indicates that the condition is not severe in that the analyte (glucose) concentration is trending back to the user's target range. Additionally, the speed at which the movement is taking place provides additional information about the severity of the glycemic event. For example, a faster rise is represented by a faster movement of the bubbles 206, 208. As programmed by the processor, this movement can be repeated at a periodic interval lasting anywhere from fractions of a second to several seconds in order to indicate the severity of the trend being displayed. For example, the faster the period, the more severely the analyte (glucose) concentration of the host is rising. In addition, more severe trends can be indicated in the graphical user interface by the use of a double arrow (or other) instead of the single arrow indicator 210.
In addition to the upper portion of FIG. 2A, the herein described graphical user interface 200 also includes a lower portion. The lower portion of the exemplary graphical user interface 200 includes a timeline 220, a historical graph 222, axis labels 224, a target analyte concentration band 226, and a current analyte reading animation 228. The current analyte reading animation 228, which may also be referred to as a “now dot” because it gives the current reading, is configured to oscillate between the depiction of FIG. 2A and FIG. 2B, e.g., along with the oscillation of the upper portion animation described above. In one or more embodiments, current analyte reading animation 228 (or “now dot”) can disappear to indicate a lack of connectivity or can change colors, flash at different rates, etc., to where the colors are rates are indicative of conditions such as analyte concentration levels with respect to concentrations, etc. In addition, an icon can be further presented in the graphical user interface 200 to indicate the loss of connectivity. In other embodiments, a broken link icon may be displayed after some period of absent data, e.g., one minute. In such a case, the broken link icon may indicate loss of connection or indicate that the sensor is connected but is delivering unstable (e.g., invalid or nonactionable) readings.
In one embodiment, the animation described herein is implemented in such a way that the image depicted in FIG. 2A smoothly transitions to the image depicted in FIG. 2B, with the respective bubbles and other elements morphing their shapes from the condition depicted in FIG. 2A to the condition depicted in FIG. 2B, and then back again. A person of ordinary skill in the art can readily implement the specific animation that cycles between FIGS. 2A & 2B using any convenient programming tool available for implementing user interfaces or applications on either a standalone mobile device or a smart phone.

As shown in FIG. 24, the current trend and current analyte concentration level, which may be determined by the processor, are used to determine the periodicity or speed of the animation. The rows (as shown on the Y axis) show the current trend as rapidly rising, rising, steady, falling, rapidly falling, or pulsing, which may be used to choose one of the graphical user interfaces of FIGS. 2A-23B. The columns (on the X axis) show the current analyte concentration level as being extreme high (501+ mg/dL), very high (500-300 mg/dL), high (299-X mg/dL; where X is the user's target high), in range (X-Y mg/dL; where Y is the user's target low), low (Y-56 mg/dL), very low (55-40 mg/dL), extreme low (39-0 mg/dL), or urgent low. Where the rows and column intersect in the table, the level indicates which speed to choose. For example: L3 corresponds to super-fast and blinking arrows with a duration of 0.4 seconds; L2 corresponds to super-fast with a duration of 0.4 seconds; L1 corresponds to fast with a duration of 1 second; and L0 corresponds to slow with a duration of 2 seconds. In other examples, different durations may be used.
By way of summary, FIGS. 25A-25I depict embodiments of animated graphical user interface elements, in accordance with one or more aspects set forth herein.
FIG. 25A shows that an increase of 0-30 mg/dL in a half-hour would trigger a rightward animation.
FIG. 25B shows that an increase of 30-60 mg/dL in a half-hour would trigger an animation that is up and to the right.
FIG. 25C shows that an increase of 60-90 mg/dL in a half-hour would trigger an upward animation.
FIG. 25D shows that an increase of 90+ mg/dL in a half-hour would trigger an upward animation with two arrows.
FIG. 25E shows that a decrease of 30-60 mg/dL in a half-hour would trigger a downward and to the right animation.
FIG. 25F shows that a decrease of 60-90 mg/dL in a half-hour would trigger a downward animation.
FIG. 25G shows that a decrease of 90+ mg/dL in a half-hour would trigger a downward animation with two arrows.
FIG. 25H shows a pulsing animation without an arrow as noted above.
FIG. 25I shows an animation with 2 bubbles orbiting, e.g., for use during sensor warmup, along with no bubble shown when there is no sensor.
FIG. 26 is a flowchart depicting a method 2600 of alerting a user using an animated graphical user interface, such as those previously described. The method 2600 at block 2610 continuously monitors an analyte concentration level of a physiological fluid. The method 2600 at block 2620 determines trend indications from a predictive algorithm, which can stored in a processor. The method 2600 at block 2630 displays, using a graphical user interface, historical analyte concentration levels and a trend indication animation. The trend indication animation comprises a visual element configured by the at least one processor to have a periodic motion between a first position and a second position on the display in one of a plurality of trend directions. The trend direction of the periodic motion between the first and second positions indicates whether the analyte concentration is trending above a target analyte concentration level, below a target analyte concentration level, or at a target analyte concentration level. The visual element is further configured with a period of the periodic motion between the first and second positions in order to indicate a severity of an excursion of the analyte concentration as compared with the target analyte concentration level. The method 2600 at block 2640 alerts a user via the graphical user interface animations noted above.
FIG. 27 depicts an embodiment of a graphical user interface 2700 which allows the inclusion of one or more user settings. The graphical user interface element 2700 may be used with the graphical user interfaces of FIGS. 2A-23B. For example, the animations described above may be turned off by default in the programming of the processor of the system. In such a case, graphical user interface element 2702 may be used to turn on (or off) animations.
FIG. 28 depicts an embodiment of a graphical user interface 2800 that includes a graphical user interface element 2810. In one embodiment, graphical user interface element 2810 provides a tip or other form of prompt for enabling animations, e.g., for use with the graphical user interfaces of FIGS. 2A-23B. For example, the graphical user interface element 2810 may be displayed to a user if the user has not tried using animation within three days (or any other configurable period) of the user beginning to use the system. In addition, the graphical user interface element 2810 can present a demonstration or trial mode. These elements can be selected to show only during certain hours of the day.
According to at least one specific implementation and if the animation is turned on, the current analyte reading animation (or “now dot”) 2805 will begin to be animated to pulse at a rate of speed that is commensurate to the severity of the reading, as previously disclosed above with respect to the event indicating bubbles of the animation. In another example, the animation may include a series of readings and/or trend arrow(s). In such a case, the animation may be different depending on a combination of the reading value and the arrow.
FIG. 29 depicts an embodiment of a graphical user interface 2900 in which a current analyte reading animation element 2910 disappears in order to indicate lack of connectivity to the user. Once connectivity is restored, the animation element 2910 will again be displayed. In addition, an icon 2920 indicative of a loss of connectivity may also be presented to a user, e.g., to indicate that connection has been lost, or to indicate that the sensor is reporting that the data is not reliable. For instance, the icon 2920 may indicate lack of connectivity or staleness of data. In one embodiment, the icon 2929 may be a broken link icon. In another embodiment, a different broken link icon may be presented under the current reading when the reading is stale (e.g., older than one minute, or some other configurable number of minutes, due to Signal Loss or Unstable Reading/No Reading condition and this icon can then stay up for up to five minutes, or some other configurable number of minutes. In another embodiment, after a specified time period without any new readings, a stale reading icon may be replaced or augmented with a Signal Loss or No Reading message on displayed on the screen. In another embodiment, once a new reading is available, the now dot indicator may return (with pulsing) and the Broken Link Icon goes away.
FIGS. 30A-30C depicts an embodiment of a graphical user interface 3000 in which a current analyte reading animation element changes colors to indicate the current reading relative to target range threshold. For example, FIG. 30A shows using a first color C1 such as red to indicate that the reading is above target. FIG. 30B shows using a second color C2 such as green to indicate that the reading is at target. FIG. 30C shows using a third color C3 such as blue to indicate that the reading is below target.
