Description

Blood sugar management system using noninvasive blood sugar measurement

[0001] The present invention relates to a blood sugar management system using non-invasive blood sugar measurement, and more particularly, to a blood sugar management system using non-invasive blood sugar measurement that non-invasively measures blood sugar and automatically provides a user with related information along with the measured blood sugar.

[0002] Diabetes is a metabolic disease characterized by high blood glucose levels, caused by insufficient insulin secretion or impaired insulin function. Glucose must enter each cell to provide energy, powering the body. Insulin is required for glucose to be utilized by each cell in the body. However, in diabetic patients, insulin deficiency prevents glucose from functioning properly, resulting in its excretion in the urine.

[0003] Diabetes is diagnosed through a blood glucose test. This test involves drawing venous blood, allowing blood clots to settle, and then isolating the clear plasma to measure glucose concentration. A diagnosis of diabetes is made when blood glucose levels are 200 mg / dL or higher, regardless of mealtime, a fasting blood glucose level is 126 mg / dL or higher, or a two-hour blood glucose level is 200 mg / dL or higher after ingesting 75 mg of glucose.

[0004] For diabetic patients, the most accurate way to manage their blood sugar is to regularly visit a hospital and have venous blood drawn to check their blood sugar and glycated hemoglobin levels. However, for various reasons, regular visits to the hospital and venous blood draws can be a cumbersome process. To address this issue, home blood glucose monitoring devices have become widespread.

[0005] Using a home blood glucose meter offers the advantage of allowing patients to measure their blood sugar without the need for regular hospital visits. However, because diabetic patients must draw blood from their own finger, it can be painful and frightening, potentially leading to side effects like spotting and swelling, and requiring replacement of consumables like test strips.

[0006] In addition, because the blood sugar measured by the self-blood sugar meter must be manually recorded and stored, users, especially the elderly, may feel very uncomfortable in terms of management after blood sugar measurement, and in the case of children, there is the problem of needing the assistance of a guardian.

[0007] In order to solve the above-mentioned problems, the technical task of the present invention is to propose a blood sugar management system using non-invasive blood sugar measurement, which manages blood sugar measurement results measured non-invasively so that a user can accurately manage blood sugar levels.

[0008] The problems solved by the present invention are not limited to those mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art from the description below.

[0009] As a means for solving the above-described technical problem, a blood sugar management system using non-invasive blood sugar measurement according to an embodiment of the present invention includes a non-invasive blood sugar diagnosis device that detects an electrical signal by contact with a user's finger and calculates a blood sugar value by applying a preset blood sugar calculation process to the detected electrical signal, and a user terminal device that receives the blood sugar value calculated from the non-invasive blood sugar diagnosis device and generates customized blood sugar information for the user based on the blood sugar value, wherein the customized blood sugar information includes blood sugar management information, diet therapy information, and exercise therapy information corresponding to a preset management period.

[0010] The above user terminal device may include a notification generating unit that generates a preset notification to the user, and a control unit that controls the notification generating unit to generate a warning notification to notify that a blood sugar measurement cycle has begun when a blood sugar value is not received from a non-invasive blood sugar diagnosis device according to a blood sugar measurement cycle for each user.

[0011] The user terminal device may include a network interface unit that receives a blood sugar value from a non-invasive blood sugar diagnosis device, and a control unit that, when a blood sugar value is received through the network interface unit, controls transmission of the blood sugar value received through the network interface unit to a designated hospital server.

[0012] The above control unit can control the network interface unit to transmit the generated customized blood sugar information to a designated guardian terminal device.

[0013] The user terminal device may include an average blood sugar value calculation unit that calculates an average blood sugar value during a preset management period, including the most recently measured blood sugar value, a score assignment unit that tracks the blood sugar value during the management period and assigns a management score, and a blood sugar information generation unit that generates customized blood sugar information including the management score.

[0014] The above customized blood sugar information may further include the most recently measured blood sugar value and the average blood sugar value during a preset management period.

[0015] The above non-invasive blood sugar diagnosis device may include a finger signal input unit that receives an electrical signal by coming into contact with a finger, a trigger signal generating unit that generates a trigger signal when contact with a finger is detected through the finger signal input unit, a sampling unit that samples an electrical signal input through the finger signal input unit by a preset number of samplings according to the trigger signal, a blood sugar value calculating unit that calculates a blood sugar value using the sampled sampling signal, and a display unit that displays the calculated blood sugar value.

[0016] According to the present invention, by measuring blood sugar using a non-invasive blood sugar diagnosis device, the fear of measuring blood sugar using a needle or a needle can be eliminated, and a blood sugar management system using non-invasive blood sugar measurement can be provided in which anyone, regardless of age or gender, can comfortably measure blood sugar.

[0017] In addition, since the non-invasive blood sugar diagnostic device and the user terminal device are connected through communication and transmit and receive information with each other, blood sugar can be automatically managed through a dedicated app, and the user can automatically receive customized information necessary for blood sugar management.

[0018] The effects of the present invention are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

[0032] Figure 1 is a network configuration diagram of a blood sugar management system using non-invasive blood sugar measurement according to one embodiment of the present invention.

[0033] Referring to FIG. 1, a blood sugar management system using non-invasive blood sugar measurement according to one embodiment of the present invention is composed of a non-invasive blood sugar diagnosis device (hereinafter referred to as a “blood sugar diagnosis device”) (100) and a user terminal device (200) that are communicatively connected to each other.

[0034] A blood sugar diagnosis device (100) is a device that diagnoses blood sugar levels by calculating blood sugar levels through electrical signals generated by contact with a user's finger. At this time, the blood sugar diagnosis device (100) calculates blood sugar levels by applying a preset blood sugar calculation process. The preset blood sugar calculation process will be described in more detail in FIG. 2, which will be described later.

[0035] As illustrated, the blood sugar diagnosis device (100) may be provided with a pair of contact portions (120) on the front of a housing (110) having a predetermined shape, which can be touched by the user's two fingers, and a display (130) for outputting various types of information. Here, a Glass LCD may be applied as the display. In addition, various buttons (not illustrated), such as a power key, may be further provided between the pair of contact portions (120) for the convenience of the user. However, in this embodiment, only one example of the blood sugar diagnosis device (100) is illustrated, and since the blood sugar value measured by the blood sugar diagnosis device (100) may be displayed through the user terminal device (200), the display (130) may not be included.

[0036] The blood sugar diagnosis device (100) uses an electrical signal through a finger to diagnose blood sugar, and can eliminate the inconvenience of the existing method of measuring blood sugar by collecting blood through a needle and the method of injecting a sensor under the skin.

[0037] The blood sugar diagnostic device (100) is manufactured in a compact and lightweight form so that users can measure their blood sugar levels anytime and anywhere. If the blood sugar diagnostic device (100) does not include a display (130), it is easier to achieve compactness and lightweight design, and manufacturing costs can also be reduced.

[0038] In addition, a pair of contact parts (120) are manufactured with an appropriate distance between them so that socially vulnerable people, such as the elderly, the disabled, and infants, can also measure blood sugar levels. In some cases, the device may be manufactured separately for children and adults. Children may have difficulty using the large blood sugar diagnostic device (100) due to their small hands, and thus may always require the assistance of a guardian. However, if a separate device for children is manufactured, children with cognitive ability can check their blood sugar levels on their own when a guardian is absent.

[0039] Although not shown, a pair of contact portions (120) that the user's finger touches in the blood glucose diagnosis device (100) may include a base layer, an electrode layer, and an insulating layer. The base layer is a layer for supporting the electrode layer and the insulating layer, and may be formed of a polymer organic film. The polymer organic film may be composed of one or more of polyimide, polyvinyl alcohol, polyamic acid, polyamide, polyethylene, polystyrene, polynorbornene, phenylmaleimide copolymer, polyazobenzene, polyphenylenephthalamide, polyester, polymethyl methacrylate, polyarylate, cinnamate polymer, coumarin polymer, phthalimidine polymer, chalcone polymer, and aromatic acetylene polymer. In addition, the electrode layer may be composed of a structure in which a transparent metal oxide, a thin film metal, and a transparent metal oxide are sequentially laminated to detect a signal from a user's finger. Additionally, the insulating layer may be composed of a curable prepolymer, a curable polymer, a plastic polymer, etc.

[0040] As illustrated, the blood sugar diagnosis device (100) is equipped with a pair of contact portions (120). However, the user does not necessarily need to touch both of the contact portions (120) with their fingers. For example, blood sugar can be diagnosed by touching one finger with either of the contact portions (120). In addition, it has been experimentally confirmed that the same blood sugar result can be obtained by touching two fingers of either the left or right hand without having to touch each of the left and right hands when the user touches the pair of contact portions (120). The blood sugar diagnosis device (100) illustrated in this embodiment is an example of a form that can provide convenience in use, and the sizes and positions of the pair of contact portions (120), the display (130), and various buttons can be modified, and the overall shape can be modified into various shapes other than a rectangular shape. The blood sugar diagnosis device (100) will be described in more detail with reference to FIG. 2 described below.

[0041] The user terminal device (200) receives blood sugar values ​​through communication with the blood sugar diagnosis device (100) and uses these blood sugar values ​​to provide the user with various information necessary for the user. For example, although the blood sugar values ​​measured by the user are displayed through the blood sugar diagnosis device (100), the blood sugar diagnosis device (100) displays the blood sugar values ​​as simple numbers. Therefore, it is difficult to easily determine the current blood sugar level without prior knowledge of blood sugar. However, the user terminal device (200) uses the blood sugar values ​​to enable the user to easily receive various information necessary for blood sugar management.

[0042] A dedicated app (or application) developed for the purpose of providing blood sugar management services using this non-invasive blood sugar measurement can be installed on the user terminal device (200). The dedicated app can be distributed from a management server (not shown). The user terminal device (200) will be described in more detail later in FIG. 3.

[0043] In the blood sugar management system utilizing the present non-invasive blood sugar measurement, the blood sugar diagnosis device (100) and the user terminal device (200) must be connected to each other so that they can communicate with each other. The blood sugar diagnosis device (100) and the user terminal device (200) may be configured to be connected to each other via a wired cable, or may be configured to be connected via a wireless network such as Bluetooth. It is preferable that the connection between the blood sugar diagnosis device (100) and the user terminal device (200) be provided in both wired and wireless modes so that the user can choose according to his / her convenience.

[0044] Figure 2 is a block diagram of the non-invasive blood sugar diagnostic device illustrated in Figure 1.

[0045] Referring to FIG. 2, a blood sugar diagnosis device (100) according to one embodiment of the present invention includes a communication unit (110), a finger signal input unit (120), a trigger signal generation unit (130), a sampling unit (140), a blood sugar value calculation unit (150), a display unit (160), a memory unit (170), and a controller (180).

[0046] The communication unit (110) supports network communication of the blood sugar diagnosis device (100), and enables transmission and reception of predetermined information through communication with the user terminal device (200). The communication unit (110) may be a wireless communication interface for convenience of use. For example, it may be implemented using Bluetooth, NFC (Near Field Communication), Zigbee, etc. In addition, the communication unit (110) may also support wired communication through hardware linkage with a terminal (not shown) to which a wired communication cable is connected.

[0047] The finger signal input unit (120) receives an electrical signal generated from a finger by making contact with the finger. To this end, the finger signal input unit is linked to a pair of contact units (120), which are hardware components mentioned in the previous embodiment. That is, when the user's finger makes contact with the pair of contact units (120), the finger signal input unit (120) receives an electrical signal through the user's finger.

[0048] The trigger signal generation unit (130) generates a trigger signal when a user's finger contact is detected through the finger signal input unit (120). The trigger signal is a signal that triggers the circuit to start operation, and in the present embodiment, it may be a square wave having a frequency in the range of 5 KHz to 100 KHz and a voltage of 1 V to 8 V. Preferably, the square wave output may be 8 KHz and 4 V.

[0049] The sampling unit (140) starts operation when a trigger signal is generated by the trigger signal generating unit (130) and samples an electrical signal a preset number of samplings during one trigger signal period. Here, the preset number of samplings means a number defined in advance.

[0050] The blood sugar value calculation unit (150) calculates a blood sugar value using a plurality of electrical signals sampled by the sampling unit (140). At this time, the blood sugar value calculation unit can calculate the blood sugar value using mathematical expressions 1 and 2. The operation of the blood sugar value calculation unit (150) may correspond to a preset blood sugar calculation process used in the blood sugar diagnosis device (100).

[0051]

[0052] In mathematical expression 1, A1 m,ave is the average value of the electrical signal corresponding to either the user's right or left finger (but only values ​​below a preset reference value in the range of 600 to 1500 are included), A1 ratiois A1 m,ave The first finger signal determined by, P1 is a first parameter preset in the range of 0.05 to 0.08, and P2 is a second parameter preset in the range of 21.05 to 35.34.

[0053]

[0054] In mathematical expression 2, BG is the final blood sugar value, A2 m,ave is the average value of the electrical signal corresponding to the other finger of the user's right and left hands (however, only values ​​below a preset reference value in the range of 600 to 1500 are included). P3 is a third parameter that is set to 1 for normal mode, 1.1 to 1.2 for pre-diabetes mode, and 1.8 to 2.2 for post-diabetes mode. P4 is a fourth parameter that is set to 210 to 220 in fasting mode and 200 to 210 in post-meal mode. P5 is a fifth parameter that is set to the range of 0.03 to 0.06. P6 is a sixth parameter that is set to 60 to 70 in fasting mode and 71 to 80 in post-meal mode. P7 is a preset percentage in the range of ±3% to 15%.

[0055] The display unit (160) displays the blood sugar level calculated by the blood sugar level calculation unit (150). The user can determine his / her current blood sugar level through the blood sugar level displayed on the display unit (160). In addition, the display unit (160) can further display certain information under the control of the controller (180) described below.

[0056] The memory unit (170) stores all information necessary for the operation of the blood sugar diagnosis device (100). For example, the memory unit (170) can store electrical signals sampled by the sampling unit (140) and blood sugar values ​​calculated by the blood sugar value calculation unit (150) for a predetermined period of time. In order to secure capacity, the memory unit (170) is preferably configured to delete the sampled electrical signals, blood sugar values, etc. after a predetermined period of time.

[0057] The controller (180) controls all operations of the blood sugar diagnosis device (100). That is, the controller (180) controls signal input and output between the communication unit (110), finger signal input unit (120), trigger signal generation unit (130), sampling unit (140), blood sugar value calculation unit (150), display unit (160), and memory unit (170).

[0058] Figure 3 is a block diagram of the user terminal device illustrated in Figure 1.

[0059] Referring to FIG. 3, a user terminal device (200) according to one embodiment of the present invention includes a user interface unit (210), a network interface unit (220), an average blood sugar value calculation unit (230), a score assignment unit (240), a blood sugar information generation unit (250), a notification generation unit (260), a storage unit (270), and a control unit (280).

[0060] The user interface (210) supports an interface between the user terminal (200) and the user. The user interface (210) can receive personal information related to blood sugar from the user. For example, personal information related to blood sugar may include age, gender, current medical condition, and hospital information.

[0061] The network interface unit (220) supports network communication of the user terminal device (200). The network interface unit (220) enables the user terminal device (200) to communicate with multiple servers via the Internet. For example, the network interface unit (220) can communicate with a blood sugar management server to update blood sugar-related information within the user terminal device (200) to the latest version. In addition, the network interface unit (220) can communicate with a hospital server (not shown) to receive necessary information from the hospital the user is visiting or transmit information related to the user's blood sugar.

[0062] In addition, the network interface unit (220) also supports short-range communication with the blood sugar diagnosis device (100). The blood sugar diagnosis device (100) is configured to enable short-range communication such as Bluetooth for miniaturization and reduced manufacturing cost, and the user terminal device (200) receives blood sugar values ​​from the blood sugar diagnosis device (100) through short-range communication. The blood sugar diagnosis device (100) can transmit the blood sugar values ​​to the user terminal device (200) every time the user measures blood sugar, and depending on the situation, the blood sugar values ​​can be transmitted to the user terminal device (200) only when the user instructs transmission.

[0063] The average blood sugar value calculation unit (230) calculates an average blood sugar value for blood sugar values ​​received from a blood sugar diagnosis device (100). When calculating the average blood sugar value, the most recently measured blood sugar value is always included, and the average blood sugar value is calculated by extracting a blood sugar value corresponding to a preset management period.

[0064] The scoring unit (240) tracks blood sugar levels over a preset management period and assigns a management score. The management score is designed to allow users to easily and intuitively understand their current blood sugar management status, and is structured in a format that is easily recognized by users. For example, a scoring system that assigns scores by dividing them into high, medium, and low levels, or a scoring system that assigns scores on a scale of 10 or 100 points, etc., may be adopted.

[0065] The blood sugar information generation unit (250) generates customized blood sugar information including the management score assigned by the score assignment unit (240), the most recently measured blood sugar value, and the average blood sugar value over a preset management period. The customized blood sugar information may include blood sugar management information, dietary information, and exercise information. The blood sugar information generation unit (250) will be described in more detail later in FIG. 4.

[0066] The notification generating unit (260) generates a preset notification to the user under the control of the control unit (280) described below. For example, if a blood sugar measurement cycle is set for each user, and the user has not measured blood sugar during the corresponding blood sugar measurement cycle, i.e., if the blood sugar value is not received from the blood sugar diagnosis device (100), the notification generating unit (260) generates a warning notification to inform the user that it is the blood sugar measurement cycle under the control of the control unit (280). If the blood sugar value is not received from the blood sugar diagnosis device (100) on the user terminal device (200), this may be because the user has not measured the blood sugar value or has measured the blood sugar value but has forgotten to transmit it. In this case, if the user has not measured the blood sugar value through the warning notification of the notification generating unit (260), the user measures the blood sugar using the blood sugar diagnosis device (100), and if the user has forgotten to transmit it, the user operates the blood sugar diagnosis device (100) to transmit the blood sugar value.

[0067] The storage unit (270) stores all information necessary for the operation of the user terminal device (200). For example, the storage unit (270) can store blood sugar information of a user of the user terminal device (200) and can store blood sugar values ​​received from a blood sugar diagnosis device (100).

[0068] The control unit (280) controls the overall operation of the user terminal device (200). That is, the control unit (280) controls signal input / output between the user interface unit (210), network interface unit (220), average blood sugar value calculation unit (230), score assignment unit (240), blood sugar information generation unit (250), notification generation unit (260), and storage unit (270).

[0069] In addition, if a blood sugar value is not received from the blood sugar diagnosis device (100) according to the blood sugar measurement cycle for each user, the control unit (280) controls the notification generation unit (260) to generate a warning notification to inform the user that it is the blood sugar measurement cycle.

[0070] In addition, the control unit (280) controls the transmission of blood sugar values ​​to at least one of a pre-registered hospital server and a guardian terminal device (not shown) when the blood sugar values ​​are received from the blood sugar diagnosis device (100) via the network interface unit (220). This allows medical staff and guardians to manage the user's blood sugar levels together. Here, the transmission of blood sugar values ​​to at least one of the hospital server and the guardian terminal device can be changed according to settings via a dedicated app.

[0071] Figure 4 is a detailed block diagram of the blood sugar information generation unit constituting the user terminal device illustrated in Figure 3.

[0072] Referring to FIG. 4, a blood sugar information generation unit (250) constituting a user terminal device (200) according to one embodiment of the present invention includes a blood sugar management information generation unit (251), a diet information generation unit (253), and an exercise therapy information generation unit (255).

[0073] The blood sugar management information generation unit (251) generates blood sugar management information including all information related to blood sugar management. For example, it can generate information including general diabetes management methods, management methods considering the user's current blood sugar level, blood sugar target values, etc.

[0074] The diet information generation unit (253) generates diet information containing information on diets necessary for diabetes management. Dietary control is paramount in diabetes management, and the foods to be avoided vary depending on each user's blood sugar level. Therefore, the diet information is generated, including foods that diabetic patients should generally be cautious about and foods that users should be cautious about. Furthermore, the diet information generation unit (253) can select foods suitable for the user and design a meal plan considering the nutritional content of those foods.

[0075] The diet plan created by the diet information generation unit (253) is provided to the user through a dedicated app. Even if the diet plan is provided by the diet information generation unit (253), the customized diet plan is useless if the user does not follow the diet plan. Therefore, as a means of ensuring that the user follows the diet plan, the user can be made to take a picture of the food he or she will eat before eating. Through this, the control unit (280) analyzes the picture of the food the user will eat, compares it with the diet plan provided to the user, determines whether the meal is eaten according to the diet plan, and the score assignment unit (240) reflects the degree of diet compliance in the management score.

[0076] The exercise therapy information generation unit (255) generates exercise therapy information including information on exercise therapy necessary for diabetes management. Exercise therapy is crucial for diabetes management, along with diet therapy, and the exercises to be performed vary depending on the user. Therefore, the exercise therapy information generation unit (255) determines a customized exercise therapy and provides the user with the corresponding information. The exercise therapy information preferably includes the type of exercise as well as the method of exercise, and provides a video of the exercise progress to ensure that the user performs the exercise correctly.

[0077] In order to determine whether the user performed the exercise based on the exercise therapy information provided to the user by the exercise therapy information generation unit (255), the user can record the type of exercise and the exercise time after the actual exercise through a dedicated app. The score assignment unit (240) can further reflect the user's exercise performance level in the management score.

[0078] FIG. 5 is a drawing illustrating a UI provided by the user terminal device illustrated in FIG. 3.

[0079] As described above, the user terminal device (200) that constitutes the blood sugar management system utilizing noninvasive blood sugar measurement may have a dedicated app installed. Through the dedicated app, users can conveniently utilize blood sugar management services utilizing noninvasive blood sugar measurement. To this end, the dedicated app provides various user interfaces (UIs) for information exchange with the user. The user terminal device (200) may also provide various types of UIs, some of which are exemplified in this embodiment.

[0080] (a) illustrates a blood sugar input UI (A). In the previous embodiment, an example was described in which a user terminal device (200) receives a blood sugar value through short-range communication with a blood sugar diagnosis device (100), but depending on the situation, the user may directly input the blood sugar value.

[0081] As shown, the blood sugar input UI (A) includes a date / time input window for entering the date and time of blood sugar measurement and a blood sugar value input window for directly entering the current blood sugar value. The blood sugar input UI (A) can be used for the purpose of entering the user's basic information when using the dedicated app for the first time, and can also be used when a communication error of the blood sugar diagnosis device (100) occurs.

[0082] (b) is an example of a blood sugar measurement / management UI (B). As illustrated, the blood sugar measurement / management UI (B) may include the user's recent blood sugar value, the average blood sugar value during the management period calculated by the average blood sugar value calculation unit (230), and may further include a blood sugar value graphed so that the user can easily understand changes in blood sugar.

[0083] Although not shown, the management score assigned by the score assignment unit (240) may be further displayed on one side of the blood sugar measurement / management UI (B). For example, a management score expression method such as displaying a preset number of star-like shapes to make it easy for the user to recognize the management score and making the shapes blink as many times as the current user's management score may be adopted. In addition, the type and location of various pieces of information included in the blood sugar measurement / management UI (B) may be changed according to the user's settings.

[0084] Figure 6 is a flowchart for explaining a blood sugar management method using non-invasive blood sugar measurement according to one embodiment of the present invention.

[0085] Herein, with reference to FIGS. 1 to 6, a blood sugar management method using non-invasive blood sugar measurement according to one embodiment of the present invention is described.

[0086] As illustrated in Fig. 1, the user measures blood sugar by touching each finger of each hand to a pair of contact portions (120) on the blood sugar diagnosis device (100). The blood sugar diagnosis device (100) measures blood sugar levels through electrical signals generated by contact with the user's fingers (S310). When blood sugar levels are measured by the blood sugar diagnosis device (100), the user causes the blood sugar diagnosis device (100) to transmit the measured blood sugar levels to the user terminal device (200). In some cases, the user may directly input the blood sugar levels into a dedicated app on the user terminal device (200) or the values ​​may be automatically transmitted to the user terminal device (200).

[0087] When a blood sugar value is input from a blood sugar diagnosis device (100) or a user, the average blood sugar value calculation unit (230) calculates an average blood sugar value for a preset management period including the most recently measured blood sugar value, and creates user-customized blood sugar information based on the current blood sugar value (S320).

[0088] The customized blood sugar information generated by the blood sugar information generation unit (250) is displayed and provided to the user via a dedicated app (S330). The customized blood sugar information may be provided in a format similar to (b) of FIG. 5, and buttons linking to diet and exercise information may be further provided on one side of the blood sugar measurement / management UI (B).

[0089] The network interface unit (220) transmits the currently measured blood sugar value to at least one of the hospital server and guardian terminal device registered in the user terminal device (200) (S340). At this time, the hospital server and guardian terminal device to which the blood sugar value is transmitted may be registered only when the user wishes to transmit his or her blood sugar value to medical staff and guardian.

[0090] Through this process, users can receive comprehensive information necessary for blood sugar management simply by measuring their blood sugar level using a blood sugar diagnostic device (100). Furthermore, since the user's blood sugar level is transmitted to a hospital or guardian, the user can receive assistance from experts or others around them for blood sugar issues that are difficult to manage on their own.

[0091] Those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering its technical spirit or essential characteristics. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
