Description

Technical Field

[0001] This invention relates to a method for transmitting and receiving unreceived biological information, and more specifically, to a method for controlling the transmission and reception of unreceived biological information in different ways by determining whether the area to which the unreceived biological information belongs is a dangerous area or a normal area based on the received adjacent biological information when there is biological information that a communication terminal has not received from a sensor transmitter. Background Technology

[0002] Diabetes is a common chronic disease in modern people. In South Korea, more than 2 million people, or 5% of the total population, have diabetes.

[0003] Diabetes is caused by a variety of factors, including obesity, stress, poor dietary habits, and congenital heredity, resulting in an absolute or relative deficiency of insulin produced by the pancreas, which fails to correct the balance of sugar in the blood, leading to an absolute increase in the sugar content in the blood.

[0004] Blood usually contains a certain concentration of glucose, from which tissue cells obtain energy.

[0005] However, when glucose levels rise excessively, it cannot be properly stored in the liver, muscles, or fat cells and instead accumulates in the blood. As a result, the blood sugar levels of diabetic patients are maintained at a much higher level than normal. As excess blood sugar is directly excreted through the tissues in the urine, the body's tissues do not have enough sugar to meet their absolute needs, leading to abnormalities in various tissues.

[0006] The characteristic of diabetes is that there are almost no noticeable symptoms in the early stages, but as the disease progresses, it manifests as unique symptoms such as polydipsia, polyphagia, polyuria, weight loss, general fatigue, itchy skin, and slow-healing wounds on the hands and feet. When the disease progresses further, complications such as vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms, neuralgia, and gangrene may occur.

[0007] In order to diagnose such diabetes and manage it to prevent the development of complications, systematic blood glucose monitoring and treatment should be carried out in parallel.

[0008] Continuous blood glucose monitoring is necessary for the management of diabetes, leading to a sustained increase in demand for blood glucose measurement devices. Various studies have confirmed that the incidence of diabetic complications is significantly reduced when diabetic patients strictly regulate their blood glucose. Therefore, regular blood glucose monitoring is extremely important for diabetic patients in order to regulate their blood glucose levels.

[0009] For blood glucose management in diabetic patients, finger prick methods are typically used. While these methods are helpful, they only display the result at the moment of measurement, making it difficult to accurately track frequently changing blood glucose levels. Furthermore, finger prick methods require multiple blood draws throughout the day for blood glucose measurement, which can be a significant burden for diabetic patients.

[0010] People with diabetes typically alternate between hyperglycemia and hypoglycemia, with emergencies occurring during hypoglycemia. Hypoglycemia occurs when glucose cannot be sustained for an extended period and can lead to loss of consciousness or, in the worst case, death. Therefore, immediate detection of hypoglycemia is crucial for people with diabetes. However, blood glucose meters that measure blood glucose intermittently have significant limitations.

[0011] To overcome the limitations of such blood sampling blood glucose meters, a continuous glucose monitoring system (CGMS) has been developed that is inserted into the human body and measures blood glucose at intervals of several minutes. This system can easily handle the management of diabetic patients and emergency situations.

[0012] A continuous glucose monitoring system includes a sensor transmitter that is attached to the user's body to measure blood glucose by extracting bodily fluids, and a communication terminal that outputs the received blood glucose values. The sensor transmitter measures the user's blood glucose and generates blood glucose information over a specified period, such as approximately 15 days, while the sensor is inserted into the body. The sensor transmitter periodically generates blood glucose information, and the communication terminal periodically receives the blood glucose information and outputs the received blood glucose information in a manner that can be confirmed by the user.

[0013] In the continuous glucose measurement system described above, the sensor transmitter and the communication terminal send and receive glucose information via wired or wireless communication. The communication terminal needs to continuously receive and send data packets from the sensor transmitter.

[0014] However, situations may arise where the communication terminal is unable to continuously receive blood glucose information from the sensor transmitter due to temporary communication interruption between the sensor transmitter and the communication terminal, or due to the user's unfamiliarity with the operation. Alternatively, when the communication terminal and the sensor transmitter are separated by a distance that prevents them from communicating with each other for a considerable period of time, the communication terminal may be unable to receive the user's blood glucose information for the corresponding time period.

[0015] Therefore, when the communication terminal cannot receive blood glucose information from the sensor transmitter, it is necessary for the communication terminal to inform the user that there is unreceived blood glucose information and to receive the unreceived blood glucose information. However, if the communication terminal repeatedly informs the user that there is unreceived blood glucose information, or repeatedly informs the user that there is unreceived blood glucose information even when the unreceived blood glucose information is not necessary for the user, it will cause inconvenience to the user.

[0055] Furthermore, unless the context clearly defines otherwise, the singular expressions used in this invention include plural expressions. In this invention, terms such as "consisting of" or "comprising" should not be construed as necessarily including all of the multiple constituent elements or steps described in this invention, but rather as potentially excluding some of the constituent elements or steps, or potentially including additional constituent elements or steps.

[0056] Furthermore, it should be noted that the accompanying drawings are only for the purpose of facilitating the understanding of the ideas of the present invention and should not be construed as limiting the ideas of the present invention to the drawings.

[0057] The method for transmitting and receiving biological information according to the present invention will now be described in more detail with reference to the accompanying drawings.

[0058] Figure 1 This is a schematic diagram illustrating a continuous blood glucose measurement system according to an embodiment of the present invention.

[0059] Reference Figure 1 A continuous blood glucose measurement system 1 according to an embodiment of the present invention includes a sensor transmitter 10 and a communication terminal 30.

[0060] The sensor transmitter 10 is attached to the body. When the sensor transmitter 10 is attached to the body, one end of the sensor of the sensor transmitter 10 is inserted into the skin and periodically extracts bodily fluids to measure blood glucose.

[0061] The communication terminal 30 is a terminal capable of receiving blood glucose information from the sensor transmitter 10 and displaying the received blood glucose information to the user. It can be a mobile terminal such as a smartphone, tablet, or laptop that can communicate with the sensor transmitter 10. Of course, the communication terminal 30 is not limited to these; it can be any type of terminal that includes communication functions and can be configured with programs or applications.

[0062] The sensor transmitter 10 transmits periodically measured blood glucose information to the communication terminal 30 based on the request of the communication terminal 30 or at each set time. In order to conduct data communication between the sensor transmitter 10 and the communication terminal 30, the sensor transmitter 10 and the communication terminal 30 can communicate with each other via wired means such as USB cable, or via wireless communication means such as infrared communication, NFC communication, Bluetooth, etc.

[0063] Here, the communication terminal 30 determines whether there is blood glucose information that has not been received from the sensor transmitter 10. When there is unreceived blood glucose information, it provides a user interface screen to inform the user that there is unreceived blood glucose information, so as to receive the unreceived blood glucose information according to the user's selection or according to the region to which the blood glucose information belongs.

[0064] In addition to blood glucose information, a wide variety of other biological information can be measured according to the field to which this invention applies. Blood glucose information is described below as an example of biological information.

[0065] Figure 2 This is a diagram illustrating an example of how blood glucose information is generated by a sensor transmitter.

[0066] First, the blood glucose signal data measured by the sensor transmitter is measured at predetermined intervals, and each measurement can be repeated multiple times. For example, the sensor transmitter measures the blood glucose signal data every 10 seconds. In this case, each measurement involves 30 blood glucose signal measurements, and the measurement time can be 1 second. Therefore, the sensor transmitter measures 30 simulated blood glucose signal data every 10 seconds.

[0067] That is, for example, blood glucose information can be measured at 10-second intervals, such as measuring blood glucose information 30 times between 2:14:25 and 2:26 pm, and then measuring blood glucose information 30 times again between 2:14:35 and 2:36 pm.

[0068] The measured blood glucose signal data is then converted into a digital signal. The sensor transmitter calculates the average value of the 30 converted blood glucose data points using a trimming average method, calculating one average value every 10 seconds. At this point, the 7 highest and 7 lowest data points are removed from the 30 blood glucose data points, and the average value A of the remaining 16 data points is calculated.

[0069] The calculated average cutting value A can be generated in 10-second increments, as shown in the figure. Six average cutting values ​​A1 to A6 can be generated in one minute.

[0070] Furthermore, six cutting averages A1 to A6 are generated every minute, and a secondary cutting average B1 is generated using these six cutting averages A1 to A6. This secondary cutting average B1 is calculated by removing the maximum and minimum values ​​from the six cutting averages A1 to A6 and averaging the remaining four values. Therefore, blood glucose information is generated every minute from a secondary cutting average B.

[0071] In this way, the blood glucose information generated every minute is stored in the sensor transmitter, and the stored blood glucose information can be generated into a data packet and transmitted to the communication terminal.

[0072] Figure 3 This is a diagram illustrating an example of a sensor transmitter generating and transmitting data packets. (See reference...) Figure 3 (a) describes an example of generating and sending data packets in each set blood glucose information generation cycle T. P Blood glucose information B1, B2, B3, B4, B5, B6, ... is generated sequentially. Each time blood glucose information is generated, a corresponding data packet P1, P2, P3, P4, P5, P6 is generated. When generating the data packet, a unique series of identifiers are assigned according to the generation order of the data packets, and the data packet is generated in a manner that includes the corresponding identifier and blood glucose information. Preferably, the identifiers for the data packets can be assigned as a sequence that increases sequentially according to the generation order, or the generation time of the data packets can be assigned as the identifiers for the data packets.

[0073] The generated data packets P1, P2, P3, P4, P5, and P6 are stored in the storage unit. When the set communication period T... S Upon arrival, the data packets P1, P2, P3, P4, and P5 stored in the storage unit will be sent to the communication terminal respectively.

[0074] refer to Figure 3 (b) describes another example of generating and sending data packets, in each set blood glucose information generation cycle T P Blood glucose information B1, B2, B3, B4, B5, B6, ... is generated sequentially. Each time blood glucose information is generated, it is stored in the storage unit. The communication cycle T is then used to... S Upon arrival, a transmission data packet P1 is generated, which includes all blood glucose information B1, B2, B3, B4, and B5 stored in the storage unit up to the communication cycle, and the generated transmission data packet P1 is sent to the communication terminal.

[0075] Figure 4 This is a functional block diagram illustrating the communication terminal of the present invention.

[0076] refer to Figure 4 To describe in more detail, when the terminal communication unit 130 receives advertisement messages sent from the sensor transmitter at predetermined communication intervals, the terminal control unit 110 communicates with the sensor transmitter via the terminal communication unit 130. While communicating with the sensor transmitter, the terminal control unit 110 receives blood glucose information from the sensor transmitter via the terminal communication unit 130 and stores the received blood glucose information in the storage unit 150. When the communication interval has elapsed, the terminal control unit 110 terminates communication with the sensor transmitter; alternatively, even before the communication interval has elapsed, the terminal control unit 110 terminates communication with the sensor transmitter after receiving all transmitted data packets from it.

[0077] On the other hand, the bioinformatics management unit 140 determines whether there is any unreceived blood glucose information based on the blood glucose information stored in the storage unit 150. When there is unreceived blood glucose information, the display unit 170 informs the user whether there is any unreceived blood glucose information, whether the unreceived blood glucose information belongs to a danger zone or a normal zone, the area to which the unreceived blood glucose information belongs, and the number of unreceived blood glucose information.

[0078] Preferably, the bioinformatics management unit 140 generates an indicator containing information such as whether there are any unreceived blood glucose messages, the region to which the unreceived blood glucose messages belong, and the number of unreceived blood glucose messages, and displays the generated indicator information on the display unit 170 to inform the user that there are unreceived blood glucose messages. When a user command for receiving unreceived blood glucose messages is input from the user interface 190, the unreceived blood glucose messages are requested from the sensor transmitter and received based on the user command.

[0079] The communication terminal communicates with the sensor transmitter in each set period to receive blood glucose information from the sensor transmitter. Preferably, in one embodiment of the present invention, the bioinformatics management unit 140 can determine whether there is any unreceived blood glucose information based on the last reception time or the last measurement time of the blood glucose information stored in the storage unit 150 and the current time point.

[0080] Preferably, in another embodiment of the present invention, when the terminal control unit 110 confirms the communication connection with the sensor transmitter, the bioinformatics management unit 140 can determine whether there is any unreceived blood glucose information based on the last reception time or the last measurement time of the blood glucose information stored in the storage unit 150 and the current time point.

[0081] Figure 5 This is a functional block diagram illustrating the bioinformatics management unit of the present invention.

[0082] refer to Figure 5 To describe it more specifically, the non-received judgment unit 141 determines whether there is any unreceived blood glucose information based on the blood glucose information received from the sensor transmitter stored in the storage unit. Here, in an example where the non-received judgment unit 141 determines whether there is unreceived blood glucose information, when communication is established between the communication terminal and the sensor transmitter, the determination of whether there is unreceived blood glucose information can be based on the blood glucose information identifier received from the sensor transmitter and the identifier of the blood glucose information last stored in the storage unit. Thus, when communication is established between the communication terminal and the sensor transmitter, by determining whether there is unreceived blood glucose information, it can be controlled so that it does not unnecessarily determine whether there is unreceived blood glucose information or unnecessarily inform the user of the existence of unreceived blood glucose information when communication between the communication terminal and the sensor transmitter is not possible or when the user intentionally disconnects communication between the sensor transmitter and the communication terminal.

[0083] In another example where the non-receipt determination unit 141 determines whether there is unreceived blood glucose information, if no new blood glucose information is stored in the storage unit after a set critical time has elapsed since the last time the blood glucose information was stored in the storage unit of the communication terminal, it can be determined that there is unreceived blood glucose information. Thus, if no new blood glucose information is received within the critical time after the last time the blood glucose information was stored in the storage unit, by determining whether there is unreceived blood glucose information, it is possible to control the communication terminal and the sensor transmitter to establish a communication connection to receive the unreceived blood glucose information in the event that a long-term communication connection between the communication terminal and the sensor transmitter is not possible.

[0084] When unreceived blood glucose information is present, the region determination unit 143 determines the region to which the unreceived blood glucose information belongs. That is, the region determination unit 143 determines whether the region containing the unreceived blood glucose information is a danger zone or a normal zone. Here, a danger zone refers to a user-defined high or low blood glucose zone, and a normal zone refers to a blood glucose zone within the normal range set by the user. The control region determination unit 143 generates an indicator message for the unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs and outputs it to the display unit.

[0085] The information acquisition unit 145 manages the unreceived blood glucose information differently depending on whether the area belongs to a danger zone or a normal zone. In the case of unreceived blood glucose information belonging to a normal zone, the information acquisition unit 145 only issues one alarm to reduce inconvenience to the user caused by frequent alarms, or blinds the indicator after a predetermined time. However, for unreceived blood glucose information belonging to a danger zone, alarms can be issued to the user more frequently than for unreceived blood glucose information belonging to a normal zone to guide the user to receive the unreceived blood glucose information. When a user command to receive unreceived blood glucose information is entered through the user interface, the information acquisition unit 145 is controlled to receive the unreceived blood glucose information from the sensor transmitter and store the received blood glucose information in the storage unit.

[0086] On the other hand, when the unreceived blood glucose information belongs to a danger zone and the corresponding unreceived blood glucose information received through the user's request is an actual danger zone, the control is that the message generation unit 147 receives a message informing the user that the corresponding unreceived blood glucose information is an actual danger zone and displays it to the user through the display unit.

[0087] Figure 6 This is a flowchart illustrating the method for sending and receiving unreceived blood glucose information according to the present invention.

[0088] refer to Figure 6 To provide a more specific description, determine whether there is blood glucose information that the communication terminal has not received from the sensor transmitter (S110).

[0089] When there is unreceived blood glucose information, the measurement time of the unreceived blood glucose information is predicted, and the region to which the unreceived blood glucose information belongs is determined from the blood glucose information received adjacent to the measurement time of the unreceived blood glucose information (S130).

[0090] An indicator is generated that includes the region to which the unreceived blood glucose information belongs and the number of unreceived blood glucose information items, and the generated indicator is displayed on the display unit (S150).

[0091] Based on the displayed indicator, determine whether a user command to request unreceived blood glucose information is entered (S170). When a user command to request unreceived blood glucose information is entered, request and receive the unreceived blood glucose information from the sensor transmitter, and display the received unreceived blood glucose information on the display unit (S190).

[0092] Preferably, the sequence of unreceived blood glucose information or the identifier of the measurement time of the unreceived blood glucose information is sent to the sensor transmitter to request the unreceived blood glucose information. The sensor transmitter can determine the unreceived blood glucose information of the communication terminal based on the identifier and provide the unreceived blood glucose information to the communication terminal.

[0093] Figure 7 An example of an indicator of the present invention is shown, such as Figure 7 As shown in (a), when there is no unreceived blood glucose information, a separate indicator will not be activated on the display of the communication terminal.

[0094] However, when there is unreceived blood glucose information, such as Figure 7 (b) or Figure 7 The activation indicator shown in (c) is activated when... Figure 7 As shown in (b), when there are unreceived blood glucose information entries that belong to the normal region, and the number of unreceived blood glucose information entries is 5, the indicator I, which includes the region to which the unreceived blood glucose information entries belong and the number of unreceived blood glucose information entries, is activated. Figure 7 When there is unreceived blood glucose information as shown in (c) and the unreceived blood glucose information belongs to the high blood glucose risk area, the indicator I, which includes information about the area to which the unreceived blood glucose information belongs, is activated.

[0095] Preferably, the indicators for unreceived blood glucose information in the normal area and unreceived blood glucose information in the danger area are displayed in different colors, so that users can not only intuitively identify the existence of unreceived blood glucose information through the indicators, but also easily and quickly identify the area to which the unreceived blood glucose information belongs.

[0096] Figure 8 This illustrates an example of a user interface screen for inputting user commands to receive information about blood glucose levels that have not been received. When the user touches an indicator icon, such as... Figure 8 As shown in (a), received blood glucose information is displayed as a graph on a timeline, and unreceived blood glucose information is also shown in the graph. After visually confirming the measurement time or the area containing the unreceived blood glucose information via the graph, the user clicks the confirmation button, and as shown... Figure 8 (b) shows a user interface screen that asks whether to receive unreceived blood glucose information, and in Figure 8 Clicking the receive button on the user interface screen shown in (b) allows you to receive any unreceived blood glucose information by entering a user command to request the reception. Figure 8 As shown in (c), when unreceived blood glucose information is received, the user interface screen for querying received blood glucose information is activated.

[0097] Figure 9 This is a flowchart illustrating the method for sending and receiving unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs, according to the present invention.

[0098] refer to Figure 9To describe it more specifically, when there is unreceived blood glucose information, the measurement time of the unreceived blood glucose information is predicted and determined (S211). The sensor transmitter measures blood glucose information at a set period. For example, regarding the measurement time of unreceived blood glucose information, the measurement time of the unreceived blood glucose information can be predicted and determined based on the measurement time of blood glucose information received and stored from the sensor transmitter. Alternatively, the measurement time of unreceived blood glucose information can be predicted and determined based on the time when the blood glucose information is not stored in the communication terminal.

[0099] Based on the measurement time of the unreceived blood glucose information, determine the adjacent blood glucose information of the time adjacent to the unreceived blood glucose information (S213), and determine whether the unreceived blood glucose information belongs to the normal region based on the adjacent blood glucose information (S215).

[0100] When the unreceived blood glucose information falls within the normal range, an indicator for the unreceived blood glucose information is output, and the system determines whether a user command requesting the reception of the unreceived blood glucose information has been entered in response to the indicator (S216). When a user command is entered, the system requests and receives the unreceived blood glucose information from the sensor transmitter (S217). Here, when requesting the unreceived blood glucose information, the system may include an identifier for the unreceived blood glucose information (e.g., the sequence of the unreceived blood glucose information, the generation time, the measurement time, etc.).

[0101] On the other hand, it is determined whether the absence of blood glucose information falls within the normal range and whether a user command requesting the absence of blood glucose information was entered within the first critical time (S218). If no user command requesting the absence of blood glucose information is entered after the first critical time, the indicator displayed on the display unit is deleted or blinding is performed (S219).

[0102] That is, when the absence of blood glucose information falls within the normal range, if no user command for receiving the absence of blood glucose information is entered within the first critical time, the indicator indicating the absence of blood glucose information is deleted or blinding is performed. Thus, unnecessary absence of blood glucose information can be easily handled without cumbersome actions or interventions from the user.

[0103] Figure 10 This is a graph used to illustrate the regions where blood glucose information was not received from the sensor transmitter, such as... Figure 10 As shown, the sensor transmitter sends blood glucose information generated at specified time intervals to the communication terminal. However, from time point t1 when communication between the sensor transmitter and the communication terminal is not connected to time point t2 when communication is reconnected, the blood glucose information generated by the sensor transmitter will not be received.

[0104] Figure 11 This is a diagram illustrating an example of determining the region to which unreceived blood glucose information belongs based on adjacent blood glucose information, such as... Figure 11 As shown in (a), the communication terminal did not receive blood glucose information from the first time point t1, and resumed receiving blood glucose information from the second time point t2. The communication terminal determines the adjacent biological information at the time before the first time point t1 and the adjacent biological information at the time after the second time point t2 based on the measurement or reception time of the blood glucose information stored in the storage unit. Based on the fact that the area to which the adjacent biological information at the time before the first time point t1 belongs is a danger zone (above TH2) and the area to which the adjacent biological information at the time after the second time point t2 belongs is also a danger zone (above TH2), it can be determined that the unreceived blood glucose information also belongs to a danger zone.

[0105] On the other hand, such as Figure 11 As shown in (b), the communication terminal did not receive blood glucose information from the first time point t1, and started receiving blood glucose information from the second time point t2. Based on the fact that the area to which the adjacent biological information at the adjacent time points before the first time point t1 belonged was the normal area (lower than TH2 and higher than TH1) and the area to which the adjacent biological information at the adjacent time points after the second time point t2 belonged was the normal area (lower than TH2 and higher than TH1), it can be determined that the unreceived blood glucose information also belonged to the normal area.

[0106] That is, in Figure 11 In one example of determining the region to which unreceived blood glucose information belongs, the region is determined based on blood glucose information received before and after the time when the unreceived blood glucose information was received.

[0107] Figure 12 This is another example of a diagram used to illustrate how to determine the region to which unreceived blood glucose information belongs based on adjacent blood glucose information, such as... Figure 12 As shown in (a), the communication terminal did not receive blood glucose information from the first time point t1, and resumed receiving blood glucose information from the second time point t2. The communication terminal determines the adjacent biological information at adjacent times before the first time point t1 based on the measurement time or reception time of the blood glucose information stored in the storage unit. Based on the fact that the area to which the adjacent biological information at adjacent times before the first time point t1 belongs is a danger zone (above TH2), it can be determined that the unreceived blood glucose information also belongs to the danger zone.

[0108] On the other hand, such as Figure 12 As shown in (b), the communication terminal did not receive blood glucose information from the first time point t1, and started receiving blood glucose information from the second time point t2. The communication terminal can determine that the unreceived blood glucose information also belongs to the normal area based on the fact that the area to which the adjacent biological information of the adjacent time before the first time point t1 belongs is the normal area (lower than TH2 and higher than TH1).

[0109] That is, in Figure 12 In one example of determining the region to which unreceived blood glucose information belongs, the region is determined based on blood glucose information received in the time period adjacent to the moment when no blood glucose information was received.

[0110] Figure 13 This is a flowchart illustrating the method for sending and receiving unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs, according to the present invention.

[0111] Continued Figure 9 The description proceeds as follows: when, based on adjacent blood glucose information, the region to which the unreceived blood glucose information belongs is determined to be a dangerous region (not a normal region), a user command requesting the unreceived blood glucose information is entered is determined (S231). Here, information regarding whether the unreceived blood glucose information belongs to a dangerous region can be displayed on an indicator.

[0112] When a user command is entered to request unreceived blood glucose information, the sensor transmitter requests and receives the unreceived blood glucose information (S233).

[0113] However, when no user command is entered requesting the receipt of unreceived blood glucose information, it is determined whether a second critical time has elapsed since the display indicator was activated (S234). If the second critical time has elapsed, an inquiry message is generated and output to inform the user that there is unreceived blood glucose information and that the unreceived blood glucose information is in a dangerous area, thus requiring receipt and confirmation (S235).

[0114] After outputting the query message, it is determined whether a user command requesting unreceived blood glucose information is entered (S237). When a user command requesting unreceived blood glucose information is entered, the sensor transmitter is requested to receive the unreceived blood glucose information.

[0115] However, if no user command is entered after the query message is entered, it is determined whether the third critical time has passed (S238). If no user command is entered after the third critical time has passed, even if the unreceived blood glucose information belongs to the danger zone, it is determined that the user did not intentionally receive the unreceived blood glucose information, and the indicator indicating the existence of unreceived blood glucose information is deleted (S239).

[0116] According to the present invention, depending on the applicable field, the dangerous area can be further subdivided into high-risk areas and low-risk areas. Based on adjacent blood glucose information, when the area to which the unreceived blood glucose information belongs is a high-risk area, regardless of whether a user command for requesting the unreceived blood glucose information is entered, it can be controlled to automatically request and receive the unreceived blood glucose information from the sensor transmitter.

[0117] On the other hand, according to the field to which this invention applies, the frequency of outputting query messages can be increased proportionally to the degree to which adjacent blood glucose information and unreceived blood glucose information exceed the normal range, or the frequency can be increased in cases where the region is in a high-risk area.

[0118] Figure 14 This is a flowchart illustrating an example of calculating the first critical time, the second critical time, or the third critical time in this invention.

[0119] refer to Figure 14 The description states that after measuring blood glucose information, the sensor transmitter stores the blood glucose information in the sensor transmitter within a set time period, such as 6 hours or 12 hours. When the storage period expires, the stored blood glucose information is deleted sequentially. When there is unreceived blood glucose information, the communication terminal predicts the measurement time of the unreceived blood glucose information (S251) and calculates the deletion time of the unreceived blood glucose information in the sensor transmitter based on the predicted measurement time (S253).

[0120] The communication terminal calculates the first critical time or the second critical time as before the deletion time arrives (S255).

[0121] On the other hand, the third critical time is calculated as the time between the second critical time and the deletion time (S257). Preferably, the sum of the second and third critical times is characterized by being calculated by distributing it at a set ratio across the total remaining time from the time point of the output indicator to the deletion time.

[0122] Figure 15 This is a diagram used to illustrate an example of calculating the first critical time to the third critical time, as shown below. Figure 15 As shown in (a), the deletion time t5 when the unreceived blood glucose information is deleted from the sensor transmitter is calculated based on the time point T1 when the unreceived blood glucose information first occurs. When the sensor transmitter and the communication terminal connect to each other to start receiving unreceived blood glucose information, the first critical time Δt1 is calculated as the time before the deletion time arrives.

[0123] On the other hand, such as Figure 15As shown in (b), the deletion time t7 of the unreceived blood glucose information being deleted from the sensor transmitter is calculated based on the time point T1 when the unreceived blood glucose information first occurs. When the sensor transmitter and the communication terminal connect to each other to begin receiving unreceived blood glucose information, the second critical time Δt2 and the third critical time Δt3 are allocated as a predetermined ratio of the total remaining time Δt4 in the sensor transmitter where the unreceived blood glucose information is stored. For example, the second critical time Δt2 can be allocated as 20% of the total remaining time, and the third critical time Δt3 can be allocated as 20% of the total remaining time. Here, the second and third critical times are allocated to the earlier part of the total remaining time, so that the unreceived blood glucose information is received or not received without waiting for the total remaining time to elapse.

[0124] On the other hand, such as Figure 15 As shown in (c), the deletion time t7 at which the unreceived blood glucose information is deleted from the sensor transmitter is calculated based on the time point T1 at which the unreceived blood glucose information first occurs. When the sensor transmitter and the communication terminal connect to each other to begin receiving the unreceived blood glucose information, the second critical time Δt2 and the third critical time Δt3 are allocated as a predetermined ratio to the total remaining time Δt4 in which the unreceived blood glucose information is stored in the sensor transmitter. For example, the second critical time Δt2 can be allocated as 20% of the total remaining time, and the third critical time Δt3 can be allocated as the total remaining time after the second critical time Δt2. Here, the third critical time Δt3 is characterized in that, when a user command is input within the third critical time Δt3, the allocation is based on a set communication time within the total remaining time, considering the possibility of connecting to the sensor transmitter to receive the unreceived blood glucose information in a way that allows for safe reception of the unreceived blood glucose information before it is deleted from the sensor transmitter.

[0125] On the other hand, the embodiments of the present invention described above can be written as programs executable on a computer and can be implemented in a general-purpose digital computer that uses a computer-readable recording medium to run the programs.

[0126] The computer-readable recording medium includes magnetic storage media (e.g., ROM, floppy disk, hard disk, etc.), optical reading media (e.g., CD-ROM, DVD, etc.), and carrier wave (e.g., transmission over the Internet) storage media.

[0127] While the invention has been described with reference to the embodiments shown in the figures, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments can be made therefrom. Therefore, the true scope of protection of the invention should be defined by the technical concept of the appended claims.
