Description

[Technical field]

[0001] The present invention relates to a method for transmitting and receiving unreceived biometric information, and more particularly, to a method for transmitting and receiving biometric information in which, when there is unreceived biometric information from a sensor transmitter, a communication terminal determines whether an area to which the unreceived biometric information belongs is a danger area or a normal area based on received adjacent biometric information, and differentially controls reception of the unreceived biometric information. [Background technology]

[0002] Diabetes is a chronic disease that occurs frequently among modern people, and in Korea, it affects more than 2 million people, or 5% of the total population.

[0003] Diabetes occurs when there is an absolute or relative deficiency of insulin produced by the pancreas due to various causes such as obesity, stress, poor eating habits, and congenital genetics, which prevents the blood from quickly balancing the sugar levels, resulting in an absolute excess of sugar in the blood.

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

[0005] However, if glucose levels increase more than necessary, it cannot be properly stored in the liver, muscles, or fat cells and instead accumulates in the blood. As a result, diabetics maintain blood sugar levels much higher than normal people, and the excess blood sugar passes directly through the tissues and is excreted in the urine, causing a shortage of sugar, which is absolutely necessary for each tissue of the body, and causing abnormalities in each tissue.

[0006] Diabetes is characterized by the fact that in the early stages there are almost no noticeable symptoms, but as the disease progresses, symptoms specific to diabetes such as excessive drinking, eating, urination, weight loss, general fatigue, itchy skin, and persistent wounds on the hands and feet that do not heal appear. As the disease progresses further, advanced complications such as vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, and gangrene appear.

[0007] In order to diagnose and manage diabetes so that it does not progress to other diseases, systematic blood glucose measurement and treatment must be carried out simultaneously.

[0008] Diabetes requires constant monitoring of blood glucose levels to be managed, and the demand for blood glucose monitoring and related devices is steadily increasing. It has been confirmed through various studies that if diabetic patients strictly control their blood glucose levels, the occurrence of diabetic complications is significantly reduced. Therefore, it is very important for diabetic patients to regularly monitor their blood glucose levels to control their blood glucose levels.

[0009] Generally, blood glucose meters using the finger prick method are used to manage blood glucose levels of diabetic patients, but since the finger prick method helps diabetic patients manage their blood glucose levels, it is difficult to accurately grasp blood glucose levels that change frequently because it only shows the results at the time of measurement. Also, blood glucose meters require blood sampling every time to measure blood glucose levels at any time throughout the day, which places a heavy burden on diabetic patients.

[0010] Diabetic patients generally go through hyperglycemic and hypoglycemic states, but emergency situations occur during hypoglycemic states. Hypoglycemic states occur when sugar is not sustained for a long period of time, and can result in loss of consciousness or, in the worst case, loss of life. Therefore, it is very important for diabetic patients to detect hypoglycemic states immediately. However, blood glucose measuring devices that measure blood glucose intermittently have clear limitations.

[0011] To overcome the limitations of blood glucose meters, a Continuous Glucose Monitoring System (CGMS) has been developed that is inserted into the human body to measure blood glucose at intervals, and can be used to easily manage diabetic patients and respond to emergency situations.

[0012] The continuous blood glucose measurement system is composed of a sensor transmitter that is attached to a part of the user's body to extract body fluids and measure blood glucose, and a communication terminal that outputs the transmitted blood glucose value. With the sensor inserted into the human body, the sensor transmitter measures the user's blood glucose for a certain period of time, for example about 15 days, and generates blood glucose information. 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 so that the user can check it.

[0013] In the above-described continuous blood glucose measurement system, the sensor transmitter and the communication terminal transmit and receive blood glucose information by wired or wireless communication, and the communication terminal must continuously receive transmission packets from the sensor transmitter.

[0014] However, due to a temporary communication interruption between the sensor transmitter and the communication terminal or the user's immature operation, the communication terminal may not be able to continuously receive blood glucose information from the sensor transmitter, or if the communication terminal and the sensor transmitter are too far apart to communicate with each other for a considerable period of time, the communication terminal may not be able to receive the user's blood glucose information for that period of time.

[0015] In this way, when the blood glucose information from the sensor transmitter cannot be received by the communication terminal, the communication terminal informs the user that there is unreceived blood glucose information, and the user needs to receive the unreceived blood glucose information. However, the communication terminal must repeatedly inform the user that there is unreceived blood glucose information, or repeatedly inform the user that there is unreceived blood glucose information even when the unreceived blood glucose information is not necessary for the user, which causes inconvenience to the user. DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0018] Another object of the present invention is to provide a method for transmitting and receiving biometric information, which reduces inconvenience to a user caused by frequent notifications of unnecessary unreceived biometric information by blinding an indicator notifying the presence of unreceived biometric information or removing it after a certain period of time when biometric information that has not been received by a communication terminal exists from a sensor transmitter and the area to which the unreceived biometric information belongs is a normal area.

[0019] Another object of the present invention is to provide a method for transmitting and receiving biometric information, which, when a communication terminal determines that unreceived biometric information from a sensor transmitter belongs to a danger area and receives the unreceived biometric information, determines whether the unreceived biometric information actually belongs to a danger area and notifies a user that the unreceived biometric information actually belongs to a danger area.

[0039] It should also be noted that the attached drawings are intended to facilitate understanding of the concept of the present invention and should not be construed as limiting the concept of the present invention.

[0040] Hereinafter, the method for transmitting and receiving biometric information according to the present invention will be described in more detail with reference to the accompanying drawings.

[0041] FIG. 1 is a schematic diagram showing a continuous blood glucose monitoring system according to one embodiment of the present invention.

[0042] Referring to FIG. 1, a continuous blood glucose monitoring system 1 according to an embodiment of the present invention includes a sensor transmitter 10 and a communication terminal 30.

[0043] The sensor transmitter 10 is attached to the body, and when the sensor transmitter 10 is attached to the body, one sensor end of the sensor transmitter 10 is inserted into the skin to periodically extract body fluids and measure blood glucose.

[0044] 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, and may be a mobile terminal capable of communicating with the sensor transmitter 10, such as a smartphone, tablet PC, or notebook. Of course, the communication terminal 13 is not limited thereto, and may be any type of terminal that includes a communication function and can be installed with programs and applications.

[0045] The sensor transmitter 10 transmits the measured blood glucose information to the communication terminal 30 periodically at the request of the communication terminal 30 or at set times. For data communication between the sensor transmitter 10 and the communication terminal 30, the sensor transmitter 10 and the communication terminal 30 may be connected to each other by a wired communication method such as a USB cable, or may be connected to each other by a wireless communication method such as infrared communication, NFC communication, Bluetooth (registered trademark), etc.

[0046] Here, the communication terminal 30 determines whether there is unreceived blood glucose information from the sensor transmitter 10, and if there is unreceived blood glucose information, provides a user interface screen to inform the user that there is unreceived blood glucose information, and receives the unreceived blood glucose information according to the user's selection or the area to which the blood glucose information belongs.

[0047] Although various types of biological information other than blood glucose information may be measured depending on the field to which the present invention is applied, blood glucose information will be described below as an example of biological information.

[0048] FIG. 2 is a diagram for explaining an example in which blood glucose information is generated by a sensor transmitter.

[0049] First, data on the blood glucose signal measured by the sensor transmitter is measured at a predetermined interval, and each measurement can be performed several times. For example, the sensor transmitter measures blood glucose signal data every 10 seconds. In this case, the blood glucose signal may be measured 30 times each time, and the time required to measure the blood glucose signal may be 1 second. Therefore, the sensor transmitter measures analog blood glucose signal data 30 times every 10 seconds.

[0050] That is, as an example, blood glucose information can be measured at 10 second intervals, such as measuring blood glucose information 30 times between 2:14:25 and 26 seconds after 2:14 PM, and then measuring blood glucose information again 30 times between 2:14:35 and 36 seconds after 2:14 PM.

[0051] The blood glucose signal data measured in this way is converted into a digital signal. The sensor transmitter calculates the average value of the 30 blood glucose information data converted into a digital signal using the cutting average method to calculate one average value every 10 seconds. At this time, the top 7 data and the bottom 7 data are removed from the 30 blood glucose information data, and the average value (A) of the remaining 16 data is calculated.

[0052] The cutting average value (A) calculated in this manner can be generated in 10-second intervals, and as shown in the figure, six cutting average values ​​(A1 to A6) can be generated for one minute.

[0053] In addition, six cutting average values ​​(A1-A6) are generated for one minute, and the generated six cutting average values ​​(A1-A6) are used to generate a second cutting average value (B1). At this time, the generated second cutting average value (B1) is calculated by removing the maximum and minimum values ​​from the six cutting average values ​​(A1-A6) and averaging the remaining four values. Therefore, blood glucose information is generated from one second cutting average value (B) per minute.

[0054] The blood glucose information data generated every minute in this manner is stored in the sensor transmitter, and the stored blood glucose information can be generated as a transmission packet and transmitted to the communication terminal.

[0055] 3 is a diagram for explaining an example of generating a transmission packet in a sensor transmitter, and looking at an example of generating a transmission packet in detail with reference to FIG. 3(a), blood glucose information (B1, B2, B3, B4, B5, B6, ...) is generated sequentially for each set blood glucose information generation period (TP), and a transmission packet (P1, P2, P3, P4, P5, P6) having the corresponding blood glucose information is generated each time blood glucose information is generated. When a transmission packet is generated, a unique series of identifiers (Identifier) ​​are assigned according to a transmission packet generation procedure, and the transmission packet is generated to have the identifier of the corresponding transmission packet and blood glucose information. Preferably, a sequence that increases sequentially according to the transmission packet generation procedure can be assigned to the transmission packet identifier, or the generation time of the transmission packet can be assigned to the transmission packet identifier.

[0056] The generated transmission packets (P1, P2, P3, P4, P5, P6) are stored in a memory unit, and when the set communication cycle (TS) arrives, the transmission packets (P1, P2, P3, P4, P5) stored in the memory unit are each transmitted to a communication terminal.

[0057] Looking at another example of generating a transmission packet with reference to FIG. 3(b), blood glucose information (B1, B2, B3, B4, B5, B6, ...) is generated sequentially for each set blood glucose information generation cycle (TP). Each time the blood glucose information is generated, it is stored in the memory unit. When the set communication cycle (TS) arrives, a transmission packet (P1) is generated that includes all of the blood glucose information (B1, B2, B3, B4, B5) stored in the memory unit up until the communication cycle, and the generated transmission packet (P1) is transmitted to the communication terminal.

[0058] FIG. 4 is a functional block diagram illustrating a communication terminal according to the present invention.

[0059] 4, when the terminal control unit 110 receives an advertisement message transmitted from the sensor transmitter at every communication interval set through the terminal communication unit 130, it establishes communication with the sensor transmitter through the terminal communication unit 130. When the terminal control unit 110 establishes communication with the sensor transmitter, it receives blood glucose information from the sensor transmitter through the terminal communication unit 130 and stores the received blood glucose information in the memory unit 150. When the terminal control unit 110 establishes communication with the sensor transmitter, the terminal control unit 110 ends communication with the sensor transmitter when the communication interval has elapsed, or ends communication with the sensor transmitter even before the communication interval has elapsed when it completes receiving a transmission packet from the sensor transmitter.

[0060] Meanwhile, the biological information management unit 140 determines whether there is unreceived blood glucose information based on the blood glucose information stored in the memory unit 150, and if there is unreceived blood glucose information, informs the user through the display unit 170 of information such as whether there is unreceived blood glucose information, whether the unreceived blood glucose information belongs to a danger zone or a normal zone, the zone to which the unreceived blood glucose information belongs, and the number of unreceived blood glucose information.

[0061] Preferably, the biological information management unit 140 generates an indicator including information on whether unreceived blood glucose information exists, information on the area to which the unreceived blood glucose information belongs, the number of unreceived blood glucose information, etc., and displays the information on the generated indicator on the display unit 170 to inform the user that unreceived blood glucose information exists. When a user command to receive unreceived blood glucose information is input from the user interface 190, the unreceived blood glucose information is requested to be received from the sensor transmitter according to the user command.

[0062] The communication terminal is connected to the sensor transmitter at set intervals to receive blood glucose information from the sensor transmitter, and preferably, in one embodiment of the present invention, the biometric information management unit 140 can determine whether there is any unreceived blood glucose information based on the current time point based on the last reception time or last measurement time of the blood glucose information stored in the memory unit 150.

[0063] Preferably, in another embodiment of the present invention, when the biometric information management unit 140 confirms that it has been communicatively connected to the sensor transmitter through the terminal control unit 110, it can determine whether there is any blood glucose information that has not been received based on the current time point based on the last reception time or the last measurement time of the blood glucose information stored in the memory unit 150.

[0064] FIG. 5 is a functional block diagram for explaining the biological information management unit according to the present invention.

[0065] More specifically, referring to FIG. 5, the unreceived blood glucose information determination unit 141 determines whether there is unreceived blood glucose information based on the blood glucose information received from the sensor transmitter and stored in the memory unit. Here, an example of the unreceived blood glucose information determination unit 141 determining whether there is unreceived blood glucose information is that when communication is connected between the communication terminal and the sensor transmitter, the communication terminal can determine whether there is unreceived blood glucose information based on the blood glucose information identifier received from the sensor transmitter and the blood glucose information identifier last stored in the memory unit. By determining whether there is unreceived blood glucose information when communication is connected between the communication terminal and the sensor transmitter in this way, it is possible to determine whether there is unnecessarily unreceived blood glucose information when communication connection between the communication terminal and the sensor transmitter is impossible or to control not to inform the user of the existence of unnecessarily unreceived blood glucose information when communication connection between the communication terminal and the sensor transmitter is impossible or when the user intentionally cuts off communication between the sensor transmitter and the communication terminal.

[0066] Here, as another example of determining whether unreceived blood glucose information exists in the unreceived information determination unit 141, when new blood glucose information is not stored in the memory unit so that a set critical time has elapsed since the time when blood glucose information was last stored in the memory unit of the communication terminal, it can be determined that unreceived blood glucose information exists. In this way, by determining whether unreceived blood glucose information exists when new blood glucose information cannot be continuously received for a critical time after blood glucose information was last stored in the memory unit, if a communication connection between the communication terminal and the sensor transmitter has not been possible for a long time, the communication terminal and the sensor transmitter can be induced to be communicatively connected to receive unreceived blood glucose information.

[0067] When there is unreceived blood glucose information, the region determining unit 143 determines the region to which the unreceived blood glucose information belongs. That is, the region determining unit 143 determines whether the region in which the unreceived blood glucose information exists is a risk region or a normal region, where the risk region means a hyperglycemia or hypoglycemia region set by the user, and the normal region means a blood glucose region within the normal range set by the user. The region determining unit 143 generates indicator information for the unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs, and controls output to the display unit.

[0068] The information acquiring unit 145 manages differently depending on whether the region to which the unreceived blood glucose information belongs is a danger region or a normal region, and in the case of unreceived blood glucose information belonging to the normal region, the information acquiring unit 145 may alarm the presence of unreceived blood glucose information only once to reduce the inconvenience of the user due to frequent alarms, or may blind the indicator after a certain time has passed, and may provide the user with more frequent alarms for unreceived blood glucose information belonging to the danger region than for unreceived blood glucose information belonging to the normal region to induce the user to receive the unreceived blood glucose information. When a user command to receive unreceived blood glucose information is input through the user interface unit, the information acquiring unit 145 receives the unreceived blood glucose information from the sensor transmitter and controls storage of the received blood glucose information in the storage unit.

[0069] Meanwhile, when the unreceived blood glucose information is determined to belong to the danger area and the corresponding unreceived blood glucose information received at the user's request is actually in the danger area, the message generating unit 147 generates a message informing the user that the corresponding unreceived blood glucose information is actually in the danger area and controls the display unit to display the message.

[0070] FIG. 6 is a flow chart illustrating a method for transmitting and receiving unreceived blood glucose information according to the present invention.

[0071] More specifically, referring to FIG. 6, the communication terminal determines whether there is blood glucose information that has not been received from the sensor transmitter (S110).

[0072] If 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 blood glucose information received adjacent to the measurement time of the unreceived blood glucose information (S130).

[0073] An indicator including an area to which the unreceived blood glucose information belongs and the number of unreceived blood glucose information is generated, and the generated indicator is displayed on the display unit (S150).

[0074] Based on the displayed indicator, it is determined whether a user command to request the unreceived blood glucose information has been input (S170). If a user command to request the unreceived blood glucose information has been input, the unreceived blood glucose information is requested and received from the sensor transmitter, and the received unreceived blood glucose information is displayed on the display unit (S190).

[0075] Preferably, an identifier such as the sequence of the unreceived blood glucose information or the measurement time of the unreceived blood glucose information is transmitted to the sensor transmitter to request the unreceived blood glucose information, and the sensor transmitter can determine the blood glucose information that the communication terminal has not received based on the identifier and provide the unreceived blood glucose information to the communication terminal.

[0076] FIG. 7 shows an example of an indicator according to the present invention. When there is no unreceived blood glucose information as shown in FIG. 7(a), no separate indicator is activated on the display unit of the communication terminal.

[0077] However, if there is unreceived blood glucose information, the indicator is activated as shown in Figure 7(b) or Figure 7(c). As shown in Figure 7(b), if there is unreceived blood glucose information and the unreceived blood glucose information belongs to the normal area and the number of unreceived blood glucose information is 5, indicator (I) including the area to which the unreceived blood glucose information belongs and the number of unreceived blood glucose information is activated. As shown in Figure 7(c), if there is unreceived blood glucose information and the unreceived blood glucose information belongs to the hyperglycemia risk area, indicator (I) including information on the area to which the unreceived blood glucose information belongs is activated.

[0078] Preferably, indicators indicating unreceived blood glucose information belonging to the normal region and unreceived blood glucose information belonging to the risk region are displayed in different colors, so that the user can intuitively recognize the presence of unreceived blood glucose information through the indicators as well as easily and quickly recognize the region to which the unreceived blood glucose information belongs.

[0079] Figure 8 shows an example of a user interface screen for inputting a user command to receive unreceived blood glucose information. When the user touches an indicator icon, the received blood glucose information is displayed as a graph on a time axis as shown in Figure 8(a), and the unreceived blood glucose information is displayed in the graph. The user visually checks the measurement time of the unreceived blood glucose information through the graph or the area to which the unreceived blood glucose information belongs, and then clicks the confirmation button to display a user interface screen for inquiring whether to receive the unreceived blood glucose information as shown in Figure 8(b). When a user command for requesting reception is input by clicking the receive button on the user interface screen displayed in Figure 8(b), the unreceived blood glucose information is received. When unreceived blood glucose information is received as shown in Figure 8(c), a user interface screen for inquiring about the received blood glucose information is activated.

[0080] FIG. 9 is a flow chart illustrating a method for transmitting and receiving unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs according to the present invention.

[0081] More specifically, referring to Fig. 9, if there is unreceived blood glucose information, the measurement time of the unreceived blood glucose information is predicted (S211). The sensor transmitter measures blood glucose information at a set period, and in one example, the measurement time of the unreceived blood glucose information can be predicted based on the measurement time of the blood glucose information received and stored from the sensor transmitter. In another example, the measurement time of the unreceived blood glucose information can be predicted based on the time when the blood glucose information is not stored in the communication terminal.

[0082] Based on the measurement time of the unreceived blood glucose information, adjacent blood glucose information at a time adjacent to the unreceived blood glucose information is determined (S213), and based on the adjacent blood glucose information, it is determined whether the unreceived blood glucose information belongs to the normal range (S215).

[0083] If the unreceived blood glucose information is in the normal range, an indicator for the unreceived blood glucose information is output, and a determination is made as to whether a user command has been input from the user requesting reception of the unreceived blood glucose information in response to the indicator (S216). If a user command has been input, the unreceived blood glucose information is requested and received from the sensor transmitter (S217). Here, the unreceived blood glucose information may include an identifier of the unreceived blood glucose information at the time of the request (e.g., sequence, generation time, measurement time, etc. of the unreceived blood glucose information).

[0084] Meanwhile, it is determined whether the unreceived blood glucose information belongs to the normal region and a user command requesting the unreceived blood glucose information is input within a first critical time (S218). If a user command requesting the unreceived blood glucose information is not input so that the first critical time has elapsed, the indicator displayed on the display unit is deleted or blinded (S219).

[0085] That is, when the unreceived blood glucose information belongs to the normal region, if a user command to receive the unreceived blood glucose information is not input within the first critical time, the indicator indicating the existence of unreceived blood glucose information is deleted or blindly processed, thereby easily processing unnecessary unreceived blood glucose information without the user's troublesome actions or intervention.

[0086] Figure 10 is a diagram for explaining a period during which blood glucose information is not received from a sensor transmitter, and as shown in Figure 10, the sensor transmitter transmits blood glucose information generated at a certain time interval to a communication terminal. However, the blood glucose information generated by the sensor transmitter is not received from the time (t1) when communication between the sensor transmitter and the communication terminal is not connected to the time (t2) when communication is reconnected.

[0087] FIG. 11 is a diagram for explaining an example of determining an area to which unreceived blood glucose information belongs from adjacent blood glucose information, and as shown in FIG. 11(a), the communication terminal does not receive blood glucose information from a first time point (t1) and starts receiving blood glucose information again from a second time point (t2). The communication terminal determines adjacent biological information of adjacent times before the first time point (t1) that has not been received and adjacent biological information of adjacent times after the second time point (t2) based on the measurement time or reception time of the blood glucose information stored in the memory unit. Since the area to which the adjacent biological information of adjacent times before the first time point (t1) that has not been received belongs is a risk area (higher than TH2) and the area to which the adjacent biological information of adjacent times after the second time point (t2) belongs is a risk area (higher than TH2), the unreceived blood glucose information can also be determined to belong to a risk area.

[0088] Meanwhile, as shown in FIG. 11(b), the communication terminal does not receive blood glucose information from a first time point (t1) and starts receiving blood glucose information again from a second time point (t2). However, since the area to which the adjacent biological information at adjacent times prior to the first time point (t1) that was not received belongs is the normal area (lower than TH2 and higher than TH1), and the area to which the adjacent biological information at adjacent times after the second time point (t2) belongs is the normal area (lower than TH2 and higher than TH1), the unreceived blood glucose information can also be determined to belong to the normal area.

[0089] That is, in FIG. 11, an example of determining the area to which the unreceived blood glucose information belongs is to determine the area to which the unreceived blood glucose information belongs based on blood glucose information received before and after the time when the blood glucose information was not received.

[0090] Figure 12 is a diagram for explaining another example of determining the region to which unreceived blood glucose information belongs from adjacent blood glucose information, and as shown in Figure 12(a), the communication terminal does not receive blood glucose information from a first time point (t1) and starts receiving blood glucose information again from a second time point (t2). The communication terminal determines adjacent biological information at adjacent times before the first time point (t2) based on the measurement time or reception time of the blood glucose information stored in the memory unit. Since the region to which the adjacent biological information at adjacent times before the first time point (t1) that has not been received belongs is a risk region (higher than TH2), the unreceived blood glucose information can also be determined to belong to the risk region.

[0091] Meanwhile, as shown in FIG. 12(b), the communication terminal does not receive blood glucose information from a first time point (t1) and starts receiving blood glucose information again from a second time point (t2). However, the communication terminal can determine that the unreceived blood glucose information also belongs to the normal range because the area to which the adjacent vital sign information of the adjacent time prior to the first time point (t1) belongs is the normal range (lower than TH2 and higher than TH1).

[0092] That is, in FIG. 12, an example of determining the area to which the unreceived blood glucose information belongs is to determine the area to which the unreceived blood glucose information belongs based on the blood glucose information received during the time adjacent to the time when the blood glucose information began not to be received.

[0093] FIG. 13 is a flow chart for explaining a method for transmitting and receiving unreceived blood glucose information based on the region to which the unreceived blood glucose information belongs according to the present invention.

[0094] Continuing with FIG 9, when the area to which the unreceived blood glucose information belongs is determined to be a risk area, not a normal area, based on the adjacent blood glucose information, it is determined whether a user command requesting the unreceived blood glucose information is input (S231). Here, information on whether the unreceived blood glucose information belongs to a risk area can be displayed on an indicator.

[0095] If a user command to request unreceived blood glucose information is input, the unreceived blood glucose information is requested to be received by the sensor transmitter (S233).

[0096] However, if a user command requesting unreceived blood glucose information is not input, the indicator is displayed and it is determined whether a second critical time has elapsed (S234). If the second critical time has elapsed, a query message is generated and output to inform the user that unreceived blood glucose information exists and that the unreceived blood glucose information belongs to a danger zone and should be received and checked (S235).

[0097] After outputting the inquiry message, it is determined again whether a user command requesting the unreceived blood glucose information has been input (S237), and if a user command requesting the unreceived blood glucose information has been input, the unreceived blood glucose information is requested to be received from the sensor transmitter.

[0098] However, after outputting the inquiry message, it is determined whether a third critical time has elapsed without a user command being input (S238). If a user command is not input so that the third critical time has elapsed, it is determined that the user has no intention of receiving unreceived blood glucose information even if the unreceived blood glucose information belongs to the danger zone, and the indicator indicating that unreceived blood glucose information exists is deleted (S239).

[0099] Depending on the field to which the present invention is applied, the risk area can be further subdivided into a high risk area and a low risk area. If the area to which unreceived blood glucose information belongs is a high risk area based on adjacent blood glucose information, the unreceived blood glucose information can be automatically requested from the sensor transmitter and reception can be controlled regardless of whether a user command to request unreceived blood glucose information has been input.

[0100] Meanwhile, depending on the field to which the present invention is applied, the frequency of outputting the inquiry message can be increased in proportion to the extent to which unreceived blood glucose information exceeds the normal range based on adjacent blood glucose information, or can be increased if it belongs to a high-risk range.

[0101] FIG. 14 is a flow chart illustrating an example of calculating the first critical time, the second critical time, or the third critical time in the present invention.

[0102] Referring to FIG. 14 in more detail, the sensor transmitter stores the measured blood glucose information for a set period of time, for example 6 hours or 12 hours, after measuring the blood glucose information, and sequentially deletes the stored blood glucose information when the storage period expires. If 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 at which the unreceived blood glucose information will be deleted from the sensor transmitter based on the predicted measurement time (S253).

[0103] The communication terminal calculates the first critical time or the second critical time before the deletion time arrives (S255).

[0104] Meanwhile, the third critical time is calculated after the second critical time has elapsed and before the deletion time arrives (S257). Preferably, the second critical time and the third critical time are calculated by allocating a set ratio to the total remaining time from the time the indicator is output to the deletion time.

[0105] Figure 15 is a diagram for explaining an example of calculating the first to third critical times, and as shown in Figure 15(a), the deletion time (t5) at which unreceived blood glucose information is deleted by the sensor transmitter is calculated based on the time (t1) at which unreceived blood glucose information first occurs. When the sensor transmitter and the communication terminal are connected to each other and start receiving unreceived blood glucose information, the first critical time (△t1) is calculated before the deletion time arrives.

[0106] Meanwhile, as shown in Fig. 15(b), the deletion time (t7) at which the unreceived blood glucose information is deleted in the sensor transmitter is calculated based on the time (t1) at which the unreceived blood glucose information is first generated. When the sensor transmitter and the communication terminal are connected to each other and start receiving the unreceived blood glucose information, the second critical time (△t2) and the third critical time (△t3) are allocated at a certain ratio in the total remaining time (△t4) in which the unreceived blood glucose information is stored in the sensor transmitter. For example, the second critical time (△t2) can be allocated as 20% of the prerequisite remaining time, and the third critical time (△t3) can be allocated as 20% of the total remaining time. Here, the second critical time and the third critical time are allocated to the front part of the prerequisite remaining time, and the unreceived blood glucose information is received or processed as unreceived without having to wait until the prerequisite remaining time has elapsed.

[0107] Meanwhile, as shown in Fig. 15(c), the deletion time (t7) at which the unreceived blood glucose information is deleted in the sensor transmitter is calculated based on the time (t1) at which the unreceived blood glucose information first occurs. When the sensor transmitter and the communication terminal are connected to each other and start receiving the unreceived blood glucose information, the second critical time (△t2) and the third critical time (△t3) are assigned a certain percentage of the total remaining time (△t4) that the unreceived blood glucose information is stored in the sensor transmitter. For example, the second critical time (△t2) can be assigned as 20% of the assumed remaining time, and the third critical time (△t3) can be assigned to the remaining total remaining time after the second critical time (△t2) has passed. Here, the third critical time (△t3) is assigned in consideration of a set communication time during which communication with the sensor transmitter can be established for the entire remaining time to receive unreceived blood glucose information so that unreceived blood glucose information can be safely received before the unreceived blood glucose information is deleted by the sensor transmitter if a user command is input within the third critical time (△t3).

[0108] Meanwhile, the above-described embodiments of the present invention can be created as a program that can be executed by a computer, and can be embodied in a general-purpose digital computer that runs the program using a computer-readable recording medium.

[0109] The computer-readable recording medium includes storage media such as magnetic storage media (e.g., ROM (Read Only Memory), floppy disks, hard disks, etc.), optically readable media (e.g., CD-ROM, DVD, etc.) and carrier wave (e.g., transmission via the Internet).

[0110] The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of the present invention should be determined by the technical ideas of the appended claims.
