Each of the above applications is incorporated by reference in its entirety.

[0002] FIELD OF THEINVENTION The present application relates to the field of analyte measurement, and more specifically, to systems, methods, and devices for visualizing analyte measurements, including alerting a user of an event. [Background technology]

[0003] Diabetes mellitus is a chronic metabolic disorder caused by the inability of the pancreas to produce sufficient amounts of insulin hormone, resulting in a reduced ability of the body to metabolize blood sugar. This failure results in hyperglycemia, i.e., an excess of glucose in the plasma. Persistent hyperglycemia and / or hyperglycemia are associated with a variety of severe symptoms and life-threatening long-term complications, such as dehydration, ketoacidosis, diabetic coma, cardiovascular disease, chronic renal failure, retinal damage, and nerve damage with the risk of limb amputation.

[0004] To achieve acceptable glycemic control, monitoring of blood or interstitial glucose is necessary. Continuous glucose monitoring (CGM) has been utilized for such glucose monitoring for the past 20 years. CGM creates data that is much richer and more complex than that of traditional episodic glucose monitoring. This additional complexity can pose numerous challenges to device users, as well as caregivers and healthcare professionals (HCPs), especially in the absence of the appropriate tools to aid in the interpretation of such data. Summary of the Invention

[0005] Thus, in one embodiment, a device for continuously monitoring an analyte concentration in a physiological fluid is presented. The device comprises a sensor, a transmitter, at least one processor, and a display. The display is configured to output a graphical user interface. The display is controlled by the at least one processor to display historical analyte concentration levels and a trend indication animation using the graphical user interface. The trend indication animation includes a visual element configured by the at least one processor to have a periodic movement between a first position and at least a second position on the display in one of a plurality of trend directions. The trend direction of the periodic movement between the first position and the second position indicates whether the analyte concentration is increasing or decreasing and the rate of change of the analyte concentration level. The visual element is further configured with a period of the periodic movement between the first position and the second position to indicate a severity of the analyte concentration fluctuation compared to a target analyte concentration level.

[0006] In another embodiment, a method for alerting a user to an event related to an analyte concentration in a physiological fluid is presented. The method includes acts of continuously monitoring an analyte concentration of a physiological fluid and displaying historical analyte concentration levels and a trend indicator animation using a graphical user interface. The trend indicator animation includes a visual element configured by at least one processor to have a periodic movement 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 movement between the first position and the second position indicates whether the analyte concentration is increasing or decreasing. The visual element is further configured with a time of the periodic movement between the first position and the second position to indicate a severity of the variation or predicted variation in the analyte concentration compared to a target analyte concentration level.

[0007] In a further embodiment, presented herein is a graphical user interface for alerting a user to an event based on continuous monitoring of an analyte concentration in a physiological fluid. The graphical user interface displays historical analyte concentration levels and a trend indicator animation. The trend indicator animation includes a visual element configured by at least one processor to have a periodic movement 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 movement between the first position and the second position indicates whether the analyte concentration is increasing or decreasing. The visual element is further configured with a period of the periodic movement between the first position and the second position to indicate a severity of the analyte concentration fluctuation compared to a target analyte concentration level.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Corresponding reference characters may indicate corresponding parts throughout the several views as presented herein. Additionally, the various examples described herein are illustrative of some embodiments, but should not be construed as limiting the scope in any manner.

[0013] The present disclosure relates to continuous glucose monitoring systems ("CGM" systems) that are provided with an enhanced graphical user interface. Unlike traditional static user interfaces, the present invention provides animations that better communicate and show trends in at least some user analyte concentration levels. Advantageously, enhanced visualizations such as animated graphical user interfaces are a practical enhancement in the field of glucometry that can simplify communication of information to users to better facilitate prompt response to events of personal concern.

[0014] Conventional systems that provide static or centralized reports cannot meet the real time needs of users involved in treatment planning, such as for diabetes mellitus. Advantageously, the present disclosure improves patient outcomes, reduces patient anxiety, and better enables CGM devices to work in a manner that meets the patient's treatment plan. Additionally, the present disclosure provides the ability to respond in real time to potentially dangerous or life-threatening ranges of motion.

[0015] Conventional analyte monitoring systems are limited in the way information can be displayed. 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 for organizing analyte monitoring data include creating a series of menus that the user must navigate to find information, hindering the usefulness of such systems. Advantageously, in one aspect, the present disclosure provides techniques for synthesizing large amounts of complex data into actionable, easy-to-use information that is delivered to the user at the point of impact. Specifically, by combining trend data and analyte value data with animation, the present disclosure allows data that was previously displayed separately to be integrated into a single display to the user, solving problems identified in conventional systems.

[0016] In a CGM system, glucose levels or concentrations can be determined by the use of a continuous glucose monitoring (CGM) sensor. CGM sensors utilize, for example, amperometric electrochemical sensor technology to measure glucose with electrodes, such as working and counter electrodes, operably connected to sensor electronics covered by a sensing membrane and a biointerface membrane attached by a clip. Examples of such systems can be 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 is incorporated herein by reference in its entirety.

[0017] 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, that coats the electrolyte phase. In this exemplary sensor, a counter electrode is provided to balance the current generated by the analyte species measured at the working electrode. For example, in the case of a glucose oxidase-based glucose sensor, the species measured at the working electrode is H2O2. The current generated at the working electrode (and flows through the circuit to the counter electrode) is proportional to the diffusion flux of H2O2 generated by this electrochemical conversion of glucose to its enzyme by-product. Thus, a raw signal may be generated that is representative of the concentration of glucose in the user's body, which may be utilized to estimate a meaningful glucose concentration value.

[0018] FIG. 1 illustrates a system 100 for continuous glucose monitoring of a host 102. The system 100 includes an analyte (e.g., glucose) sensor 112 that transmits analyte concentration level values ​​via wireless transmission 110 to a display unit 104. The display unit 104 may be a custom-built unit, a smartphone, a tablet, or any other wireless-enabled mobile or stationary 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 its at least one processor, receives, stores, and analyzes data from the analyte sensor 112. For example, the device may be a smartphone, such as an iPhone available from Apple Inc., of California, that includes an ARM microprocessor. In such a case, the smartphone may execute an application or app that performs the functions of the display unit 104 described herein.

[0019] The analyte sensor 112 may be coupled with an electronics module that includes a wireless transceiver to facilitate 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 touch screen for input and may run an operating system to host a graphical user interface, described below. The analyte sensor 112 may be any type of continuous glucose monitoring sensor, such as, but not limited to, those applied subcutaneously, transdermally, transcutaneously, including implantable or other types. The continuous glucose monitoring sensor transmits a data stream that includes the level of glucose concentration in the host 102. The display unit 104 may receive, store, and process this data stream. For example, various algorithms known in the art may be executed on at least one processor of the display unit 104 to process the data stream, etc.

[0020] It should be understood that the specific glucose analyte measurement examples described herein are meant to illustrate particular implementations and are not intended to limit the present disclosure in any way. The techniques described herein may be used to visualize continuous analyte measurements in other configurations than that shown in FIG. 1, for example, using other sensors for glucose or other analytes found in interstitial fluid.

[0021] Figures 2A-23B show various embodiments of animated graphical user interfaces presented on the display unit 104 of Figure 1 for visualizing analyte measurements. As an overview of Figures 2A-23B, each pair of views, such as Figures 2A and 2B, represents a single representative user interface screen with an animated visualization shown in two different states.

[0022] 2A and 2B show a graphical user interface 200 presented on a display unit. In an upper portion, the graphical user interface 200 includes a colored bubble 202, a white bubble 204, a first trend showing a bubble 206, a second trend showing a bubble 208, and a trend showing an arrow 210.

[0023] The color of the colored bubble 202 is configured to change 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, the determination that a level is at a target level or range is based on the level being within a range of values, where levels below the target or below the target range are represented by bubbles colored blue, levels above the target analyte concentration level are represented by bubbles colored red, and levels at the target analyte concentration level are represented by bubbles colored green. The white bubble 204, as shown in the embodiments shown herein, is static and includes a numerical value of the current analyte concentration level near the center of the bubble 204. In other embodiments, the concentration level may be indicated using other visual cues, such as by a cluster of points or objects, a bar of a bar chart embedded in the bubble, numbers located in different parts of the bubble, etc.

[0024] 2A and 2B, two trends showing bubbles 206, 208 are located below the white bubble 204. As can be seen in FIG. 2A, the trend showing bubble 206 appears below the white bubble 204, and the second trend showing bubble 208 appears above the white bubble 204. As shown in FIG. 2A, the first trend and the second trend showing bubbles 206, 208 move upwards. 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, a double arrow, a blinking arrow(s), and any other directional indicator. In some examples, the arrow may also move to indicate the direction of the trend. In other examples, when animation is turned off, one of the paired bubble images used to show the animation, i.e., FIG. 2A, FIG. 3A, FIG. 4A, etc., may appear as a static image and still function as a directional indicator to the user.

[0025] In the graphical user interface 200, a trend indicator animation is displayed to the user by the graphical user interface 200 oscillating periodically between the states of Figures 2A and 2B, with transitions between states being described herein. The complete animation of the graphical user interface 200 includes a first trend and a second trend showing bubbles 206, 208 starting from the positions shown in Figure 2A, with each bubble 206, 208 moving upward to the positions of Figure 2B, and then moving downward back to the positions of Figure 2A. The upward direction of this movement indicates that the predicted trend of the analyte concentration level is increasing. The direction of the arrow indicator 210 in combination with the displayed current analyte concentration level within the white bubble 204 indicates the severity of this increase. For example, an upward arrow indicator 210 in combination with a displayed analyte concentration value of 300 mg / dL indicates a severe glycemic event, while a downward arrow indicator 210 with a displayed analyte concentration value of 300 mg / dL indicates a less severe glycemic event in that the analyte (glucose) concentration is trending back into the user's target range. Additionally, the speed at which the movement is made provides additional information regarding 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 periodic intervals ranging from fractions of a second to several seconds to indicate the severity of the displayed trend. For example, the faster the period, the greater the rise in the host's analyte (glucose) concentration. Additionally, a more severe trend can be indicated in the graphical user interface by the use of a double arrow (or other) instead of a single arrow indicator 210.

[0026] In addition to the top portion of FIG. 2A, the graphical user interface 200 described herein also includes a bottom portion. The bottom portion of the exemplary graphical user interface 200 includes a timeline 220, a history 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 the "current point" to give the current reading, is configured to oscillate between the depictions of FIG. 2A and FIG. 2B, for example, along with the oscillating top portion animation described above. In one or more embodiments, the current analyte reading animation 228 (or "current point") can disappear or change color and blink at a different rate to indicate a lack of connectivity. The color and rate indicate a state, such as an analyte concentration level versus concentration, etc. Additionally, an icon may be further presented in the graphical user interface 200 to indicate a loss of connectivity. In other embodiments, an irregularly shaped link icon may be displayed after some period of missing data, such as after one minute. In such cases, the irregularly shaped link icon may indicate a loss of connection, or that the sensor is connected but is delivering erratic (eg, invalid or inoperable) readings.

[0027] In one embodiment, the animations described herein are implemented in such a way that the image shown in Figure 2A smoothly transitions to the image shown in Figure 2B, with each bubble and other element morphing their shape from the state shown in Figure 2A to the state shown in Figure 2B and then back again. One skilled in the art may easily implement the particular animations that cycle between Figures 2A and 2B using any convenient programming tools available for implementing user interfaces or applications on either standalone mobile devices or smartphones.

[0050] FIG. 24 illustrates one embodiment of an animation decision matrix for determining the animated graphical user interface present on the display unit of FIG. 1. As shown in FIG. 24, the current trend and the current analyte concentration level, which may be determined by a processor, are used to determine the periodicity or speed of the animation. Each row (as shown on the Y-axis) indicates that the current trend is rapidly rising, rising, steady, falling, rapidly falling, or pulsating, which may be used to select one of the graphical user interfaces of FIGS. 2A-23B. The columns (on the X-axis) indicate the current analyte concentration level as very 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), very low (39-0 mg / dL), or imminently low. Where rows and columns intersect in the table, the level indicates which speed to select. For example, L3 corresponds to a super fast and blinking arrow with a duration of 0.4 seconds, L2 corresponds to a super fast with a duration of 0.4 seconds, L1 corresponds to a fast with a duration of 1 second, and L0 corresponds to a slow with a duration of 2 seconds. In other embodiments, different durations may be used.

[0052] FIG. 26 is a flow chart illustrating a method 2600 of alerting a user using an animated graphical user interface such as those described above. The method 2600 at block 2610 continuously monitors an analyte concentration level of a physiological fluid. The method 2600 at block 2620 determines a trend indicator from a predictive algorithm, which may be stored in a processor. The method 2600 at block 2630 displays the historical analyte concentration level and a trend indicator animation using a graphical user interface. The trend indicator animation includes a visual element configured by at least one processor to have a periodic movement 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 movement between the first position and the second position indicates whether the analyte concentration is trending above a target analyte concentration level, trending below a target analyte concentration level, or trending at a target analyte concentration level. The visual element is further configured with a period of the periodic movement between the first position and the second position to indicate a severity of the analyte concentration fluctuation compared to the target analyte concentration level. The method 2600 at block 2640 alerts the user via the above graphical user interface animation.

[0053] Figure 27 illustrates an embodiment of a graphical user interface 2700 that allows for the inclusion of one or more user settings. The graphical user interface element 2700 may be used in conjunction with the graphical user interfaces of Figures 2A-23B. For example, the animations described above may be turned off by default in the programming of the system's processor. In such a case, the graphical user interface element 2702 may be used to turn the animations on (or off).

[0054] FIG. 28 illustrates an embodiment of a graphical user interface 2800 that includes a graphical user interface element 2810. In one embodiment, the graphical user interface element 2810 provides information or other forms of input prompts to enable animations, for use with, for example, 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 used an animation within three days (or any other configurable period) since beginning to use the system. Additionally, the graphical user interface element 2810 may present a demonstration or trial mode. These elements may be selected to show only during certain times of the day.

[0055] According to at least one particular implementation, when animation is turned on, the current analyte reading animation (or "current point") 2805 begins to pulsate animated at a rate commensurate with the severity of the reading, as previously disclosed above with respect to the event showing the animation bubble. In another example, the animation may include a series of readings and / or trend arrow(s). In such a case, the animation may differ depending on the combination of readings and arrows.

[0056] FIG. 29 illustrates an embodiment of a graphical user interface 2900 in which the current analyte reading animation element 2910 disappears to indicate a lack of connectivity to the user. When connectivity is restored, the animation element 2910 reappears. Additionally, an icon 2920 indicating a loss of connectivity is also presented to the user, and may indicate, for example, that the connection has been lost or that the sensor is reporting that the data is unreliable. For example, the icon 2920 may indicate a lack of connectivity or the data is out of date. In one embodiment, the icon 2929 may be an irregularly shaped link icon. In another embodiment, a different irregularly shaped link icon may be presented below the current reading when the reading becomes invalid (e.g., older than 1 minute, or other configurable minutes due to signal loss or unstable / no reading condition, and this icon may remain displayed for up to 5 minutes, or other configurable minutes). In another embodiment, the invalid reading icon may be replaced or expanded with a signal loss or no reading message displayed on the screen after a specified period that does not include a new reading. In another embodiment, when a new reading is available, the current point indicator may return (pulsing) and the irregularly shaped link icon may move away.

[0057] 30A-30C show an embodiment of a graphical user interface 3000 in which a current analyte reading animation element changes color to indicate the current reading relative to a target range threshold. For example, FIG. 30A shows the use of a first color C1, such as red, to indicate that the reading is above target. FIG. 30B shows the use of a second color C2, such as green, to indicate that the reading is on target. FIG. 30C shows the use of a third color C3, such as blue, to indicate that the reading is below target.
