Description

[Technical field]

[0001] The present invention relates to a computer-implemented method, a mobile device, and a computer program for managing medical data, e.g., glucose concentrations, by an electronic disease management system including detecting a change in local time between generation of a first set of medical data and generation of a second set of medical data. [Background technology]

[0002] Diabetes is a disease in which the body's ability to produce or respond to insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated blood glucose levels. If left untreated, diabetes can lead to many complications. Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic states, or death. Serious long-term complications include cardiovascular disease, stroke, chronic kidney disease, foot ulcers, and eye damage.

[0003] Self-monitoring of glucose concentration with a glucose meter or continuous glucose monitoring sensor and self-administration of insulin with a pen or pump are the typical methods by which diabetic patients treat their diabetes.

[0004] The diabetic patient may further use a computing device, such as a mobile communication device (e.g., a smart phone, personal digital assistant, tablet, or similar device) connected to his or her medical device. The results of the blood glucose measurement or the units of insulin delivered are, for example, transmitted wirelessly from the medical device to the computing device.

[0005] The computing device may process, store, analyze, and display medical data in graphs over time. Thus, diabetes-related medical devices such as blood glucose meters, continuous glucose monitoring sensors, insulin pens or pumps may include means for tracking time, such as an internal digital clock, and store time-stamped medical data (e.g., measured glucose concentrations, delivered insulin units) for real-time or later transmission to the computing device. Based on the imported data including the timestamp, the cumulative amount of insulin delivered to the user, so-called insulin onboard, may also be seen, or glucose trends may be determined. In either case, reliability and understandability of the data together with the corresponding timestamp is essential for further analysis and for patient treatment decisions.

[0006] Methods for preparing time-related data from different medical devices are known in the art. For example, WO 2016 / 087714 discloses a method for monitoring a user's glucose level. A server communicates with blood glucose meters via the Internet. The blood glucose meters transmit their own current time together with the measurements and timestamps. The server then compares the current time transmitted by the glucose meters with the server time, detects possible discrepancies, and adjusts the timestamps to a known and correct reference time, such as Universal Coordinated Time (UTC).

[0007] EP 2988672 discloses a diabetes management system comprising a number of blood glucose meters in data communication with a diabetes management application residing on a mobile phone. Each meter has its internal real-time clock (RTC) and the mobile phone has its internal telephone time, which is set to GMT when the mobile phone is connected to a network. When the mobile phone is not connected to a network, the telephone time is set to be equal to the meter's RTC time. For each meter, the diabetes management application determines a delta time between the telephone time and the meter's RTC. The management application stores the received measurements together with the RTC timestamp from the meter along with the corresponding calculated time delta. The management application then calculates a new timestamp for each measurement by adding the time delta to the corresponding RTC timestamp. The measurements are stored together with the calculated new timestamp.

[0008] As long as all medical data is acquired in one time zone and all times and clocks in the medical device and in the computing device are synchronized to a common time, the processing of the imported data in the computing device works well. However, problems arise when medical data collected in different time zones is displayed and analyzed, because in this case, some of the timestamps may relate to times before the time change, while other timestamps may relate to times after the time change.

[0009] WO 2019 / 199920 discloses that a patient with diabetes (PWD) may often travel between locations in different time zones. Thus, a user interface of a mobile device may utilize information about a universal time concept and a current time zone of the mobile device to display time-related treatment information to a patient with diabetes based on the current (new) time zone of the mobile device. The mobile device may, for example, detect the current time zone of the mobile device and convert a timestamp associated with previously recorded bolus dose information from the universal time concept to a time based on the current time zone of the mobile device.

[0010] WO 2019 / 243907 discloses an app that detects a time change event and adds a delta time to a timestamp generated by a blood glucose meter (BGM) at a previous time. This is repeated for every timestamp of the current import and for every time change of the BGM time that may affect the imported timestamp. Finally, the time difference between the app UTC time and the latest BGM time is added to the BGM timestamp. This results in a new additional UTC timestamp. The converted UTC timestamp is converted back to a display timestamp by adding the time difference between the current local app time and the current app UTC time.

[0011] Despite the progress made in accounting for time changes, managing medical data created in different time zones remains a challenge. In particular, there is a need to improve the display and usability of displayed medical data. When a time zone is changed and the displayed time of past events and values ​​is altered, this may mean, for example, that a medical event that occurred in the afternoon before the time zone change now appears in the evening. This makes it more difficult to correlate medical events retroactively.

[0012] Issues to be resolved Therefore, it is desirable to provide a method and device that addresses the above-mentioned technical challenges of managing medical data using mobile devices, such as consumer electronics mobile devices. In particular, a method and device should be proposed that provides an easy way to track or interpret past medical data, which may also be useful in determining appropriate current or future treatments for managing a medical condition, such as a diabetic condition.

[0017] In a first aspect, a computer-implemented method for managing medical data by an electronic disease management system, comprising a processing unit and a display unit, is disclosed. The method includes the following steps (note that the method may include further method steps not listed below): a) receiving, by a processing unit, a first set of medical data of a patient, the medical data of the first set of medical data being associated with respective first timestamps indicating respective generation times of the medical data of the first set of medical data according to a first local time; b) associating, by the processing unit, the medical data of the first set of medical data with respective second timestamps indicative of a generation time of each of the medical data of the first set of medical data according to a standard time concept; c) receiving, by the processing unit, a second set of medical data of the patient, where the medical data of the second set of medical data are associated with respective third timestamps indicative of respective generation times of the medical data of the second set of medical data according to a second local time; d) associating, by the processing unit, the medical data of the second set of medical data with respective fourth time stamps indicative of a generation time of each of the medical data of the second set of medical data according to a standard time concept; e) detecting, by the processing unit, a change in local time between the generation of the first set of medical data and the generation of the second set of medical data; f) providing, by the processing unit, a first display signal representing the first set of medical data and the second set of medical data over time on a first graph, wherein the medical data of the first set of medical data and the second set of medical data are in chronological order in the first graph of their generation times according to a reference time concept, the spacing between the medical data in the time direction in the first graph is directly proportional to the difference between their generation times according to the reference time concept, and a change in local time between the generation of the first set of medical data and the generation of the second set of medical data is shown on the first graph.

[0018] The term "medical data" as used herein is a broad term and should be given its ordinary and customary meaning to those skilled in the art and should not be limited to a special or customized meaning. The term may specifically refer to health-related information associated with a patient, but is not limited thereto. The medical data may include, by way of example, quantitative medical data, such as the concentration of one or more test subjects in the patient's bodily fluids, a drug dosage administered to the patient, and / or an amount of carbohydrates ingested by the patient. Thus, the term medical data may include one or more types of medical data, such as, for example, a glucose concentration in the patient's bodily fluids, a hormone (e.g., insulin, c-peptide and / or glucagon) concentration in the patient's bodily fluids, an insulin dosage administered to the patient, and / or an amount of carbohydrates ingested by the patient. In one example, the test subject is glucose. The term medical data may include, among other things, the patient's glucose concentration in a bodily fluid, such as a blood glucose concentration, a glucose concentration in interstitial fluid, urine, saliva or another type of bodily fluid, and / or an insulin dosage administered to the patient. In one embodiment, the medical data includes the patient's blood glucose concentration and / or an insulin dosage administered.

[0019] In one example, the medical data of the first set of medical data is a test subject concentration and / or a drug dosage, and the medical data of the second set of medical data is another test subject concentration and / or another drug dosage. In another example, the medical data of the first set of medical data is a glucose concentration, and the medical data of the second set of medical data is another glucose concentration.

[0020] The set of medical data includes one or more medical data. For example, the first set of medical data includes at least three medical data (m1, m2, m3) of the patient, and the second set of medical data includes at least three further medical data (m4, m5, m6) of the patient. The medical data of the first set of medical data and / or the second set of medical data may all relate to the same type of medical data about the patient (e.g., all blood glucose concentrations) or may relate to different types of medical data about the patient (e.g., some of the medical data of the first set of medical data and / or the second set of medical data are blood glucose concentrations of the patient, while other medical data of the first set of medical data and / or the second set of medical data are insulin doses administered to the patient). In one embodiment, the medical data of the first set of medical data and the second set of medical data are of the same type, such as glucose concentrations in the patient's body fluids (e.g., blood or interstitial fluid) or insulin doses administered to the patient.

[0021] The term "electronic disease management system" as used herein is a broad term and should be given its ordinary and customary meaning to those skilled in the art, and should not be limited to a special or customized meaning. The term electronic disease management system (in short, the system herein) may specifically refer to, but is not limited to, a mobile communication device, such as a mobile phone, particularly a smartphone. Additionally or alternatively, the system may refer to a personal computer, a tablet computer, or another type of computer. The system comprises a processing unit. The system may also comprise a memory. The memory may, for example, store previously received medical data and associated timestamps. The system further comprises a display unit.

[0022] The processing unit is configured to receive the medical data and the associated respective first and third timestamps, and further associate the received medical data with the respective second timestamps. The processing unit is further configured to provide a display. The processing unit is configured to provide a display signal to a display unit, for example, including a touch-sensitive display. Additionally or alternatively, the display unit may include a liquid crystal display, a thin film transistor display, a light-emitting diode display, or any other device capable of converting a signal from the processor into a light output.

[0023] The medical data and the associated respective first and third timestamps may be received from one or more medical devices, such as, for example, a glucose meter and / or a drug (e.g., insulin) delivery device. The transmission of the medical data and the associated respective first and third timestamps may be by wired transmission or may in particular be by wireless transmission (e.g., using Bluetooth or NFC technology). The medical data and the associated respective first and third timestamps may additionally or alternatively be received from the system's memory and / or from alternative data sources, such as a cloud source.

[0024] The processing unit may be provided with one or more processors. The one or more processors may be integral with a single component of the system. However, it should be noted that the one or more processors may also be located separately in individual components, such as, for example, a glucose meter, a drug delivery device, and a mobile phone, and the glucose meter and drug delivery device may be communicatively coupled to the mobile phone. In this case, the mobile phone, as well as the glucose meter and drug delivery device may all be considered components of the system. Accordingly, the system may include multiple components having one or more processors, each communicatively coupled to one or more of the other components.

[0025] The method of the present invention comprises the steps of: a) receiving, by a processing unit, a first set of medical data of a patient, wherein the medical data of the first set of medical data are associated with respective first timestamps indicating respective generation times of the medical data of the first set of medical data according to a first local time;

[0026] The term "local time" (also referred to as "time zone") as used herein is a broad term and should be given its ordinary and customary meaning to those skilled in the art and should not be limited to any special or customized meaning. The term local time (or time zone) may specifically refer to, but is not limited to, a time that has a specified time offset from Coordinated Universal Time that is specific to a geographic location (or a zone defined due to local needs such as the boundaries between countries and their subdivisions). The specified time offset may be date dependent when considering time changes due to daylight saving time. The offset of a local time from Coordinated Universal Time (commonly referred to as UTC) is usually an integer number of hours, although some local times, such as in India and Nepal, are offset by an additional 30 or 45 minutes. The first local time is, for example, Central European Standard Time (CET), which is one hour ahead of UTC, Central European Summer Time (CEST), which is two hours ahead of UTC, Eastern Standard Time (ET), which is five hours behind UTC, Eastern Daylight Time (EDT), which is four hours behind UTC, Pacific Time (PT), which is eight hours behind UTC, Pacific Daylight Time (PDT), which is seven hours behind UTC, or China Standard Time (CST), which is eight hours ahead of UTC. The second local time is, for example, Central European Standard Time (CET), which is one hour ahead of UTC, Central European Summer Time (CEST), which is two hours ahead of UTC, Eastern Standard Time (ET), which is five hours behind UTC, Eastern Daylight Time (EDT), which is four hours behind UTC, Pacific Time (PT), which is eight hours behind UTC, Pacific Daylight Time (PDT), which is seven hours behind UTC, or China Standard Time (CST), which is eight hours ahead of UTC, but in the present invention, the second local time is different from the first local time.

[0027] Coordinated Universal Time is independent of geographic location. Therefore, UTC is also independent of where the patient is when generating the medical data, or where any component of the system is located. In the present invention, the first local time is different from the second local time, i.e., the time offset of the first local time from Coordinated Universal Time is different from the time offset of the second local time from Coordinated Universal Time.

[0028] The generation of the medical data refers, for example, to the creation of the medical data, for example, the measurement of a concentration of a test subject in a patient's body fluid or the delivery of an amount of a drug to a patient. The generation time of the medical data of the first set of medical data according to the first local time refers to a respective current first local time when the medical data was generated, for example, the current first local time when the test subject concentration of the patient was measured or the amount of a drug was delivered to the patient. The generation time of the medical data of the second set of medical data according to the second local time refers to a respective current second local time when the medical data was generated, for example, the current second local time when the test subject concentration of the patient was measured or the amount of a drug was delivered to the patient. The indication of the generation time of each of the medical data according to the local time includes an instruction that enables the processing unit to convert the timestamp into a reference time concept. Thus, a timestamp indicating the generation time of each piece of medical data according to a local time may, for example, include information about i) the current time (e.g., 14:35), ii) the current date (e.g., April 11, 2021), and iii) the local time (e.g., CET), or the time offset of the local time relative to UTC (e.g., UTC+01:00), in order to clearly indicate the generation time of each piece of medical data.

[0029] The medical data associated with the time stamps indicating respective generation times according to the first local time may refer, for example, to glucose concentrations in the patient's bodily fluids measured in a first time zone having a first local time, or to drug doses delivered to the patient in the first time zone having a first local time. When the patient is located in the first time zone having a first local time, the patient generates, for example, a first set of glucose concentrations in the bodily fluids by performing corresponding glucose concentration measurements in the first time zone having a first local time, and / or an administered drug dose by performing corresponding drug dose self-administration in the first time zone having a first local time. The glucose concentration measurements may be performed by the patient in the first time zone having a first local time using a glucose meter, such as a blood glucose meter or a continuous glucose measurement device. The administration of a drug (e.g., insulin) dose may be performed by the patient in the first time zone having a first local time using a drug delivery device, such as an insulin pen or an insulin pump. When performing a glucose measurement using a glucose measuring device or delivering an amount of insulin using an insulin delivery device (e.g., an insulin pen or an insulin pump), the medical device may not only store the measured glucose concentration or the amount of insulin delivered, but also store the generation time of the medical data as a timestamp (with an associated timestamp indicating the generation time of each of the medical data according to the first local time), in this example the time of each glucose concentration measurement or the time of each delivery of the amount of insulin, according to the first local time, together with the current local time when the measurement was performed or the drug delivery was performed. In the present invention, the processing unit not only receives a first set of medical data, for example a plurality of glucose concentrations measured in a body fluid, but also the medical data of the first set of medical data are associated with respective timestamps indicating the generation time of each of the medical data of the first set of medical data according to the first local time.Thus, in addition to receiving the first set of medical data, the processing unit also receives respective time stamps indicating the generation time of each of the medical data of the first set of medical data according to the first local time. In one embodiment, the association of the medical data with the respective first time stamps indicating the generation time (116) of each of the medical data of the first set of medical data according to the first local time may not be performed on the medical device, but on the smartphone to which the medical data is wirelessly transmitted. The medical data together with the associated respective time stamps indicating the generation time of each of the medical data according to the local time may be stored in the memory of the system, and the processing unit of the system may also receive the medical data together with the associated respective time stamps therefrom (e.g., instead of receiving them from the medical device).

[0030] The method of the present invention comprises the steps of: b) further comprising associating, by the processing unit, the medical data of the first set of medical data with respective second timestamps indicating a generation time of each of the medical data of the first set of medical data according to a standard time concept.

[0031] The term "reference time concept" as used herein is a broad term and should be given its ordinary and customary meaning to those skilled in the art and should not be limited to a special or customized meaning. The term reference time concept may specifically refer to, but is not limited to, a time concept that is independent of the time zone in which the system is located. The reference time concept is, for example, Coordinated Universal Time (UTC). For example, the reference time concept may alternatively be Unix Time, or any other time that is independent of a specific time zone. To associate the medical data of the first set of medical data with the respective second timestamps, the processing unit can convert the generation time (also referred to as the time of generation) according to the first local time to the generation time according to the reference time concept, and the generation of the converted timestamp (second timestamp) includes adding a first delta to the generation time according to the first local time, the first delta corresponding to a time offset (delta) of the first local time relative to the reference time concept. The time offset can be a positive or negative value. That is, the term "addition" includes adding a positive value to the timestamp and subtracting a value from the timestamp.

[0032] The method of the present invention comprises the steps of: c) receiving, by the processing unit, a second set of medical data of the patient, where the medical data of the second set of medical data are associated with respective third timestamps indicative of respective generation times of the medical data of the second set of medical data according to a second local time; d) further comprising associating, by the processing unit, the medical data of the second set of medical data with respective fourth timestamps indicating a generation time of each of the medical data of the second set of medical data according to a standard time concept.

[0033] Reference is made to the above description which can be transferred to steps c) and d). Instead of the first set of medical data, a second set of medical data is received in step c), and a third timestamp indicates the respective generation time according to the second local time (whereas the first timestamp indicated the respective generation time according to the first local time). The second set of medical data is then associated with a respective fourth timestamp indicating the respective generation time of the medical data of the second set of medical data according to the reference time concept (whereas the first set of medical data was associated with the respective second timestamp). By associating the first set of medical data and the second set of medical data with the respective timestamp indicating the respective generation time according to the reference time concept, they can be set relative to each other in terms of generation order. In one embodiment, the second set of medical data is generated after the first set of medical data is generated, and the patient travels from a first time zone having a first local time to a second time zone having a second local time between the generation of the first set of medical data and the generation of the second set of medical data, and the first set of medical data was generated in the first time zone and the second set of medical data was generated in the second time zone. In one example, the second set of medical data is generated and received after the first set of medical data is generated and received by the processing unit.

[0034] The method is: e) detecting, by the processing unit, a change in local time between the generation of the first set of medical data and the generation of the second set of medical data; f) providing, by the processing unit, a first display signal representing the first set of medical data and the second set of medical data over time on a first graph, wherein the medical data of the first set of medical data and the second set of medical data are in chronological order in the first graph of their generation times according to a reference time concept, the spacing between the medical data in the time direction in the first graph is directly proportional to the difference between their generation times according to the reference time concept, and a change in local time between the generation of the first set of medical data and the generation of the second set of medical data is shown on the first graph.

[0035] The change in local time may be detected by the processing unit in, for example, a change in the time offset of the local time to UTC, as indicated by the first and third timestamps. The change in local time may also be detected by the processing unit in, for example, a change in location data (e.g., detectable by GPS signals received by the processing unit) associated with the first and second sets of medical data. The processor may link the location data with time zone information. In one embodiment, the change in local time is detected, for example, when the first local time is CET and the second local time is GMT.

[0036] The first graph may be, for example, a line graph or a scatter plot to show changes in the medical data over time. The first graph may, for example, visualize glucose concentration over time in a line graph or a scatter plot. Time may be on the x-axis of the graph and, for example, glucose concentration may be on the y-axis of the graph. The axes themselves do not necessarily need to be displayed on the graph. The first graph includes a first set of medical data, a second set of medical data, and an indication of the change in local time between the generation of the first set of medical data and the generation of the second set of medical data.

[0037] The term "chronological order" used herein is a broad term and should be given its ordinary and customary meaning to those skilled in the art, and should not be limited to a special or customized meaning. The term chronological order may specifically refer to the arrangement of medical data in a graph in the order of their generation, and the order of their generation is determined according to, but not limited to, a reference time concept. Because the second timestamp and the fourth timestamp depend on the same reference time concept, the arrangement of medical data in chronological order is easily possible.

[0038] The interval between medical data in the first graph in the time direction is directly proportional to the difference in their generation time according to the reference time concept means that the distance (ΔX) of the interval in the time direction in the graph of two medical data m1 and m2 having generation times t1 and t2 (where t2>t1) according to the reference time concept follows the formula ΔX=A*ΔT, where A is a constant and ΔT is the difference in the generation time of the two medical data according to the reference concept. This allows the patient to easily interpret the medical data. The medical data generated at equal time differences according to the reference time concept are equally spaced apart in the time direction in the first graph. As an example, assuming a first set of medical data m1, m2 and m3 generated in this order, and a second set of medical data m4, m5 and m6 generated in this order and after m1 to m3 are generated, where m1 and m2 are generated with a time difference of one hour according to a reference time concept, m3 and m4 are generated with a time difference of one hour according to a reference time concept, and m5 and m6 are generated with a time difference of one hour according to a reference time concept, m1 to m6 can be plotted in a line graph or a scatter plot, where m1, m2, m3, m4, m5 and m6 are shown in this order on the graph in the time direction, and m1 and m2, m3 and m4, and m5 and m6 are equally spaced in the time direction on the graph. The change in local time between the generation of the first set of medical data and the generation of the second set of medical data is shown in the first graph. Thus, in the example provided, it is visible between m3 and m4. The first graphical representation method has the further advantage that events such as glucose measurements are visualized in the order and absolute time differences as they were experienced by the patient, no data is lost, and local time changes are visible to the patient, simplifying interpretation of the data for the patient.

[0039] In one example, the method includes displaying the entire first graph on the display unit. Thus, the patient can see the entire first graph at one time. In another example, the method includes displaying only a sub-region of the first graph. Thus, the patient can see only a sub-region of the first graph at one time. However, in the case of a touch-sensitive display unit, the patient can scroll through the first graph to see all the portions of the first graph. Thus, the processing unit may provide the first display signal by the processing unit to the display unit, and the display unit does not necessarily have to display all the first display signals at one time, for example, when the patient scrolls the graph on the touch-sensitive display, a first sub-region of the first graph at a first time point may be displayed and a second sub-region of the first graph at a second time point may be displayed. In another embodiment, all the first display signals are displayed on the display unit for the patient to see at one time. Thus, in this case, in the case of a touch-sensitive display, the patient does not have to scroll through the graph to see all the medical data of the first set of medical data and the second set of medical data. In one example, the first set of medical data and the second set of medical data are generated within an absolute time frame of 24 or 18 hours or less. In this example, the entire first graph may be displayed on the display unit for the patient to view at one time.

[0040] In one embodiment, the method includes displaying a target zone for the medical data on a first graph. The target zone indicates a boundary within which the quantitative medical data should fall. Outliers (medical data that falls outside the boundary) indicate that a therapy for treating a patient's disease should be adjusted.

[0041] The method is: b1) providing, by the processing unit, a second display signal representing the first set of medical data over time on a second graph, wherein the medical data of the first set of medical data are in chronological order in the second graph of their generation times according to the first time concept or a reference time concept, and the spacing between the medical data in the time direction in the second graph is directly proportional to the difference in their generation times according to the reference time concept.

[0042] In one example, the method includes displaying the entire second graph on the display unit. Thus, the patient can see the entire second graph at one time. In another example, the method includes displaying only a sub-region of the second graph. Thus, the patient can see only a sub-region of the second graph at one time. In the case of a touch-sensitive display unit, the patient can scroll through the second graph to see all the portions of the second graph. Thus, the processing unit may provide the second display signal by the processing unit to the display unit, and the display unit does not necessarily have to display all the second display signals at one time, for example, when the patient scrolls the graph on the touch-sensitive display, a first sub-region of the second graph at the first time point may be displayed and a second sub-region of the second graph at the second time point may be displayed. In another embodiment, all the second display signals are displayed on the display unit for the patient to see at one time. Thus, in this case, in the case of a touch-sensitive display, the patient does not have to scroll through the graph to see all the medical data of the first set of medical data.

[0043] The second display signal may be provided to (and displayed on) the display unit before the second set of medical data is received by the processing unit. In one embodiment, when the first graph or subregion thereof is displayed on the display unit, the second graph or subregion thereof is no longer displayed on the display unit. In one embodiment, the first display signal replaces the second display signal.

[0044] The first set of medical data may be generated while the patient is in a first time zone having a first local time and the second set of medical data may be generated while the patient is in a second time zone having a second local time. A second display signal may be provided to the display unit when the patient is in the first time zone and the first display signal may be provided to the display unit when the patient is in the second time zone.

[0045] In one embodiment, the second display signal includes a signal for representing a time scale of the second graph showing when the medical data of the first set of medical data was generated according to the first local time. The time scale may be particularly shown on the x-axis of the second graph. The time scale may include, for example, at least two time scale divisions and time labels of the at least two time scale divisions, so that when the patient views the second graph, the generation time of each of the first set of medical data according to the first local time can be identified based thereon.

[0046] Additionally or alternatively, the first display signal may include, for example, a signal for representing a first time scale portion of a first graph showing when the medical data of the first set of medical data was generated according to a first local time, and a second time scale portion of the first graph showing when the medical data of the second set of medical data was generated according to a second local time.

[0047] The first time scale portion and the second time scale portion may be particularly shown on the x-axis of the first graph. The first time scale portion may, for example, include at least two first scales and time labels of the at least two first scales, so that when the patient views the first graph, the generation time of each of the first set of medical data according to the first local time may be identified based thereon. The second linear time scale portion may, for example, include at least two second scales and time labels of the at least two second scales, so that when the patient views the first graph, the generation time of each of the second set of medical data according to the second local time may be identified based thereon.

[0048] In one embodiment, all the scales are evenly spaced in the first graph. Specifically, the distance between two adjacent scales shown in the first graph may be the same (whether each adjacent scale is two first scales, two second scales, or a first scale and a second scale). The at least two first scale labels may indicate times in a linear ascending order according to the first local time. The at least two second scale labels may indicate times in a linear ascending order according to the second local time. However, due to a change in the local time between the generation of the first set of medical data and the generation of the second set of medical data, there may appear to be a non-linearity between the end of the first scale label and the beginning of the second scale label. In one embodiment (e.g., when moving from East to West), the first scale label of the second scale labels may indicate a time equal to or earlier than the time of the last scale label of the first scale labels. In one embodiment (e.g., when moving from west to east), the first of the second tick labels may indicate a later time than would result from using purely linear ascending tick labels.

[0049] For example, because insulin secretion is underpinned by circadian rhythms, it is important for a patient (or medical practitioner) to see not only the patient's glucose concentration, but also the respective generation time according to the local time the data was generated in the graph. If all past generation times of medical data are converted to generation times according to the current local time where the patient is located, and the medical data is displayed in a graph over time showing only the current local time for all medical data, the patient (or medical practitioner) may misinterpret the need for insulin, for example, at a particular time of day or overnight.

[0050] In one embodiment, the display unit is a touch-sensitive display unit including a controller unit for controlling the display unit and optionally a sensing unit. The sensing unit senses, for example, touch gestures on the display. The controller is, for example, configured to receive a first display signal and control the display unit to display the first graph or a sub-region thereof at a time. The controller may also be configured to receive a second set of display signals and control the display unit to display the second graph or a sub-region thereof at a time before receiving the second set of medical data.

[0051] The controller is, for example, configured to receive a first display signal and control the display unit to display a first sub-region of the first graph at a first time point, the sensing unit is configured to sense a first scroll action of the user in the first sub-region of the first graph in a backward or forward direction of the displayed chronological medical data, and the controller is configured to control the display unit to display a second sub-region of the first graph at a second time point instead of the first sub-region of the first graph in response to the sensing of the first scroll action, the second sub-region of the first graph being located at least partially behind or in front of the previously displayed chronological medical data in the first sub-region of the first graph. When time is on the x-axis of the graph, the scroll action backwards can be a swipe gesture to the right with a finger on the display. When time is on the x-axis of the graph, the scroll action forwards can be a swipe gesture to the left with a finger on the display.

[0052] In another example, the controller is configured, for example, to receive a first display signal and control the display unit to display a first subregion of a first graph at a first time point, the sensing unit is configured to sense a first zoom-out action of a user on the first subregion of the first graph, and the controller is configured, in response to sensing the zoom-out action, to control the display unit to display a second subregion of the first graph at a second time point, the second subregion of the first graph including the first subregion and another medical data located behind or before the previously displayed chronological medical data in the first subregion of the first graph.

[0053] In one embodiment, the first display signal includes an additional signal representing the first set of medical data and the second set of medical data in a list in chronological order of their generation times according to a reference time concept, where next to each medical data of the first set of medical data is indicated a respective generation time according to a first local time and next to each medical data of the second set of medical data is indicated a respective generation time according to a second local time. The list (also referred to herein as the first list), or a part thereof, may be displayed on the display unit in addition to displaying the first graph or a sub-area of ​​the first graph at the first time point. The controller may be further configured to receive the first display signal and control the display unit to display the first portion of the list at the first time point on the display unit of the user's electronic device, the sensing unit being configured to sense a second scrolling action of the user in the first portion of the list backward or forward of the displayed chronological medical data, and the controller being configured to control the display unit to display, in response to sensing the second scrolling action, instead of the first portion of the list, the second portion of the list at the second time point, located at least partially behind or before the previously displayed chronological medical data in the first portion of the list. The controller may be further configured to control the display unit to display the first partial area of ​​the first graph and the first portion of the list at once, and at least a portion of the medical data shown in the first partial area of ​​the first graph is also shown in the first portion of the list.

[0054] One or more of the medical data of the first set of medical data and / or the second set of medical data may further be associated with at least one of a plurality of tags. The tag provides, for example, time-related contextual information of the respective medical data. Non-time-related tags, such as tags indicating sports events or illness events, may also be used. In one example, the associated tags are also received by the processing unit, and the first display signal includes a signal representing the time-related tag associated with the respective medical data in the first graph and / or list, preferably the list. The plurality of time-related tags include, for example, tags for breakfast, lunch, dinner, bedtime and night. The search function may be displayed on the display unit to search the first and second sets of medical data for medical data associated with one of the multiple tags, sense a search request for one of the multiple tags by the sensing unit, determine by the controller whether the searched tag is associated with one or more of the first and second sets of medical data, and provide a third display signal to the display unit representing the medical data associated with the searched tag (or a part of the medical data associated with the searched tag) in the second list in chronological order of their generation time according to the reference time concept. The third display signal representing the medical data associated with the searched tag (or a part of the medical data associated with the searched tag) in the second list in chronological order of their generation time according to the reference time concept is provided only if the step of determining that the searched tag is associated with one or more of the first and second sets of medical data is true. For example, the most recent medical data is displayed at the top of the second list. The second list does not include any medical data not associated with the searched tag. When only a portion of the medical data associated with the searched tag is displayed in the second list, this portion includes the most recent (according to the reference time concept) medical data of the displayed medical data and, optionally, one or more additional medical data associated with the searched tag in chronological order of their generation time according to the reference time concept.The third display signal may be displayed on the display unit in addition to or instead of displaying the first display signal. The generation time according to the reference time concept is not usually displayed in the list and / or graph. Instead, the second list may show the respective generation time according to the first local time next to each medical data of the first set of medical data associated with the searched tag, and the second list may show the respective generation time according to the second local time next to each medical data of the second set of medical data associated with the searched tag.

[0055] In one embodiment, the method includes displaying a search function on the display unit for searching the first and second sets of medical data for medical data associated with one of the multiple tags, sensing a search request for one of the multiple tags by the sensing unit, determining by the controller whether the searched tag is associated with one or more of the first and second sets of medical data, and displaying a selected sub-region of the first graph on the display unit, the selected sub-region including at least the most recent chronologically of the medical data associated with the searched tag. Alternatively, the selected sub-region includes at least one or more medical data of the first set of medical data associated with the searched tag. The selected sub-region may be displayed instead of or in addition to the first graph or a sub-region thereof. As another example, the controller is configured to receive a first display signal and control the display unit to display a first sub-region of the first graph at a first time point, a search function for searching the first and second sets of medical data for medical data associated with one of the multiple tags is displayed on the display unit, a search request is sensed by the sensing unit for one of the multiple tags, the controller determines whether the searched tag is associated with one or more of the first and second sets of medical data, and when the step of determining that the searched tag is associated with one or more of the first and second sets of medical data is true, the controller is configured to control the display unit to display a selected sub-region, the selected sub-region of the first graph including at least the most recent of the medical data associated with the searched tag. The selected sub-region may be specifically displayed instead of the first sub-region of the first graph at a second time point.

[0056] Tags add context to medical data. They can help understand a patient's diabetes and the relationship between specific conditions and glucose levels, for example by finding patterns in glucose levels. Optimizing treatment becomes easier with some context to the data, for example in the form of tags.

[Brief description of the drawings]

[0069] [Figure 1] 1 illustrates an embodiment of an electronic disease management system. [Diagram 2] 1 illustrates a flow chart of an embodiment of a method for managing medical data. [Diagram 3] 1 illustrates an embodiment of a mobile device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0070] 1 shows an exemplary embodiment of an electronic disease management system 110. The electronic disease management system comprises a processing unit 102, which includes three processors 104, 106 and 108, and a display unit 112. The processing unit 102: receiving from the glucose measuring device 100 a first set of glucose concentrations of the patient, the first set of glucose concentrations being associated with respective first timestamps indicating a time of generation of each of the glucose concentrations of the first set of glucose concentrations according to a first local time; - associating the glucose concentrations of the first set of glucose concentrations with respective second time stamps indicative of a time of generation of each of the glucose concentrations of the first set of glucose concentrations according to a standard notion of time; receiving from the glucose measuring device 100 a second set of glucose concentrations for the patient associated with respective first timestamps indicative of a time of generation of each of the glucose concentrations in the second set of glucose concentrations according to a second local time; - associating the glucose concentrations of the second set of glucose concentrations with respective fourth time stamps indicative of a time of generation of each of the glucose concentrations of the first set of glucose concentrations according to a standard notion of time; - detecting a change in local time between the generation of a first set of glucose concentrations and the generation of a second set of glucose concentrations; - Providing a first display signal to the display unit 112.

[0071] A flow chart of one exemplary embodiment of a method 132 for managing medical data is shown in FIG. 2. The method 132 specifically includes the following steps, which may be performed in a given order. Moreover, different orders may be possible. It may be possible to perform two or more of the method steps fully or partially simultaneously. It may further be possible to perform one, two or more, or even all of the method steps once or repeatedly. The method 132 includes: a) receiving, by a processing unit (designated 134), a first set of medical data (114) of a patient, the medical data of the first set of medical data being associated with respective first timestamps indicating respective generation times (116) of the medical data of the first set of medical data according to a first local time; b) by a processing unit (denoted by reference numeral 136), associating the medical data of the first set of medical data with respective second timestamps indicative of a generation time of each of the medical data of the first set of medical data according to a reference time concept; c) receiving, by a processing unit (designated 138), a second set of medical data of the patient, the medical data of the second set of medical data being associated with respective third timestamps indicative of a generation time of each of the medical data of the second set of medical data according to a second local time; d) associating, by a processing unit (designated 140), the medical data of the second set of medical data with respective fourth time stamps indicative of respective generation times (117) of the medical data of the second set of medical data according to a standard time concept; e) detecting, by a processing unit (designated 142), a change in local time between the generation of the first set of medical data and the generation of the second set of medical data; f) providing, by a processing unit (denoted by reference numeral 144), a first display signal representing the first set of medical data and the second set of medical data on a first graph (118) over time, where the medical data of the first set of medical data and the second set of medical data are in chronological order of their generation times according to a reference time concept in the first graph, the intervals between the medical data in the time direction in the first graph are directly proportional to the difference between their generation times according to the reference time concept, and a change in local time (120) between the generation of the first set of medical data and the generation of the second set of medical data is shown on the first graph; Includes. The method 132 may include additional method steps not listed in FIG.

[0072] FIG. 3 illustrates an embodiment of a mobile phone 110 as an example of an electronic disease management system. A front view of the mobile phone is shown. The mobile phone comprises a processing unit 102 located inside the mobile device and is therefore only shown in FIG. 3 with dashed lines. The mobile phone further comprises a display unit 112. A first graph 118 over time is displayed in the top half of the display unit. A list 122 is displayed in the bottom half of the display unit. The first graph is a scatter plot showing the change in the patient's glucose concentration over time. The first graph includes a representation of a first set of glucose concentrations and a second set of glucose concentrations, as well as a change 120 in local time between the generation of the first set of glucose concentrations and the generation of the second set of glucose concentrations. The glucose concentrations 114 are illustrated in FIG. 3 as black dots. The three black dots on the left side of the first graph 118 represent the glucose concentrations of a first set of glucose concentrations measured by the patient in a first time zone having a first local time, and the two black dots on the right side of the first graph 118 represent the glucose concentrations of a second set of glucose concentrations measured by the patient in a second time zone having a second local time. The glucose concentrations of the first and second sets are in chronological order of their generation times according to a reference time concept in the first graph, and the interval between the glucose concentrations in the time direction in the first graph is directly proportional to the difference between their generation times according to the reference time concept. The target zone 126 in the first graph indicates the lower and upper limits of the glucose target concentration zone for the patient. For example, the limits are 80 mg / dl and 140 mg / dl (blood glucose concentration). A blood glucose concentration below the lower limit of 80 mg / dl may be considered a hypoglycemic event. A blood glucose concentration above the upper limit of 140 mg / dl may be considered a hyperglycemic event.

[0073] The first graph further shows a first time scale portion indicating when the glucose concentrations of the first set of glucose concentrations were generated according to a first local time (CET as an example), and a second time scale portion indicating when the glucose concentrations of the second set of glucose concentrations were generated according to a second local time (GMT as an example). The first time scale portion includes a first scale (a first of three displayed scales is illustratively shown as 128) and scale time labels (7:00, 8:00, 9:00) (a first of three displayed scale time labels is illustratively shown as 130), so that when a patient views the first graph, the generation time of each of the first set of glucose concentrations according to the first local time can be identified based thereon. The second time scale portion includes two second scales and two second scale time labels (9:00, 10:00) in the illustrated embodiment, so that when a patient views the first graph, the generation time of each of the second set of glucose concentrations according to the second local time can be identified based thereon. Due to a change in local time 120 (shown to be approximately 9:35 CET) between the generation of the first set of medical data and the generation of the second set of medical data, there appears to be a non-linearity between the end of the first scale label (9 o'clock) and the beginning of the second scale label (also 9 o'clock). In the example, a patient is traveling, for example, from Vienna, where a first set of glucose concentrations were measured, to London, where a second set of glucose concentrations were measured.

[0074] The generation times 117 of the second set of glucose concentrations and the generation times 116 of the first set of glucose concentrations are shown in a list (122) at the bottom of the display unit in chronological order of their generation times according to a standard time concept. This includes an indication of the respective local time (CET or GMT in the example). The chronologically most recent measured glucose concentration is shown at the top of the list, followed by the remaining measured glucose concentrations in chronological order. The glucose concentrations measured at the indicated generation times are shown in a circle as an example. As an example, 114 shows a measured glucose concentration of 75 mg / dl (measured at 7:15 CET). This glucose concentration is further associated with a breakfast tag to indicate that the glucose concentration was measured when breakfast started. This tag simplifies the interpretation of the displayed data by the user. The patient in this case can easily see from the graph that he was in a hypoglycemic state at 7:15 CET when breakfast started, which is an indication that the previously administered evening basal insulin dose was not properly selected.
