The scale and range of information technologies industries connected with a network are expanded according to the arrival of the ubiquitous age. As an aging society and a silver industry grow, a lot of persons turn attention to health and medical fields. Connection between the ubiquitous technology and a health care enables a lot of persons to be provided with various medical services without going to a hospital. For example, a diabetic patient checks a blood sugar using portable blood sugar measuring equipment without going to a hospital.

However, the burden of chronic disease increases due to the rapid aging of the population, and management of the chronic disease and provision of a preventive service are still insufficient. Since the chronic disease occurs due to wrong habits, it is necessary to prevent and manage the chronic disease in advance and thoroughly. In particular, the diabetes and associated complications are able to be managed and prevented through blood sugar control and education and an exact blood sugar test. Accordingly, it is required a blood sugar managing system capable of minimizing the burden of expense due to the diabetes individually and socially.

A blood sugar patient needs to check a blood sugar periodically. To this end, inconveniently, the diabetic patient puts and holds a blood sugar measurement unit in a separate case or bag to check a blood sugar periodically. Furthermore, conventionally, a user measures a blood sugar using a blood sugar measurement unit and separately records a measured blood sugar value by hand. Alternatively, to record a measured blood sugar value, inconveniently, the user operates another terminal (e.g., a cellular phone, a smart phone, etc.) in measuring a blood sugar and enters the measured blood sugar value into the terminal.

Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concept of the prevent invention to those skilled in the art. The prevent invention may be defined by scope of the claims. Meanwhile, the terminology used herein to describe embodiments of the invention is not intended to limit the scope of the invention.

Even though it is not defined, all terms (including technical or scientific terms) used herein, all terms have the same meaning as being generally accepted by the general technology in the art belonging to prevent invention. It will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this disclosure and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. General descriptions about the well-known configurations may be omitted so as not to obscure the subject matter of the prevent invention. A configuration which is equal to or corresponds to drawings in the prevent invention is possible using the same reference numerals.

A blood sugar managing watch according to an embodiment of the prevent invention may be a wrist watch-type terminal which include a blood sugar meter therein and is able to measure a blood sugar. The blood sugar managing watch may include a blood sugar strip connector which is installed at a housing provided in a wrist watch shape and is connectable with a blood sugar strip and a blood sugar meter which is embedded in the housing. When the blood sugar meter is connected with the blood sugar strip connector, the blood sugar meter may automatically activate a blood sugar measurement task to measure a blood sugar of blood on a blood sugar strip. In an embodiment, a sensing unit may detect that the blood sugar strip is connected to the blood sugar strip connector and may generate an interrupt event. The interrupt handler may control the blood sugar meter in response to the interrupt event so as to activate the blood sugar measurement task.

According to an embodiment of the prevent invention, the convenience to hold may be secured by embedding the blood sugar meter in the wrist watch-type terminal. A blood sugar may be measured by automatically activating the blood sugar measurement task only through the action that a user connects a blood sugar strip to the blood sugar strip connector included in the housing, thereby making it possible to measure a blood sugar in an easy, simple manner and for a user unused to use an electronic device to measure a blood sugar easily.

The blood sugar managing watch according to an embodiment of the prevent invention may activate a blood sugar measurement task when the blood sugar strip is connected to the blood sugar strip connector and may measure a blood sugar of blood on the blood sugar strip. The blood sugar managing watch may automatically integrate and store an identifier (ID) of the blood sugar managing watch, information of a blood sugar measured by the blood sugar meter, and management time information of the blood sugar information in a single data packet. Since one-to-one correspondence exists between the ID of the blood sugar managing watch, the ID of the blood sugar managing watch may indicate a user ID namely. The blood sugar measurement data integrated in the single data packet may be transmitted to a personal mobile terminal of a user or an external device such as a hospital server using a bidirectional wireless communication.

Accordingly, blood sugar measurement data of a user may be conveniently collected for each user by adding private information of the user to basic medical information (blood sugar information), and the blood sugar measurement data may be overall managed through the external device. Thus, it may be possible to provide an effective blood sugar management medical service by making better use of the blood sugar measurement data. Furthermore, it may be possible to manage a blood sugar thoroughly by notifying a personal terminal of a protector or an external device (e.g., a medical team terminal) of a blood sugar non-measurement notification message when a user does not measure a blood sugar at a predetermined blood sugar management schedule. Also, it may be possible to quickly cope with a dangerous situation that a blood sugar is excessively high.

FIG. 1is a perspective view of a blood sugar managing watch according to an embodiment of the prevent invention.FIG. 2Ais a perspective view of a cover of a blood sugar managing watch ofFIG. 1, shown in an opened state.

The blood sugar managing watch100may include a housing110, a blood sugar strip connector120, a blood sugar meter130, a cover140, a display unit150, a user interface unit160, and a connector170.

The housing110may have a general wrist watch shape, and opposite ends of the housing110may be connected with a wristband-shaped watch strip for wearing on a user's wrist. The blood sugar strip connector120may be formed in a shape corresponding to a blood sugar strip10so as to be connected with the blood sugar strip10and may be installed on one side of the housing110so as to be opened or closed by the cover140. The blood sugar strip connector120may be disposed in a direction to face a user's body, with the blood sugar managing watch100worn on a user's wrist, thereby improving the convenience of the user in the process to insert the blood sugar strip10and gather a blood in measuring a blood sugar.

The blood sugar meter130may be embedded in the housing110. The blood sugar meter130may automatically activate a blood sugar measurement task when the blood sugar strip10is connected to the blood sugar strip connector120and may measure a blood sugar in blood put on the blood sugar strip10. The cover140may be installed in the housing110so as to open and close the blood sugar strip connector120. When the blood sugar strip connector120and the connector170for connection with a charger, various sensors, or a storage medium are not used, the cover140hides the connector170and the blood sugar strip connector120, thereby improving a design function and preventing rainwater or foreign substances from flowing therein. In an embodiment illustrated inFIG. 2A, the cover140may be provided to be rotated on the basis of a hinge shaft (not shown) placed at an end side thereof and may be closed or opened by lifting up and down the cover140. In an embodiment, the cover140may be closed or opened when pushed in an on-touch manner, and a spring (not shown) may be installed on a lower surface of the cover140such that an opened state is maintained by the spring.

The blood sugar strip10may have a blood insertion portion11on which blood gathered for blood sugar measurement is put and may be provided to be inserted into or released from the blood sugar strip connector120. The blood sugar strip10, as illustrated inFIG. 2B, may be connected with the blood sugar strip connector120such that the blood insertion portion11is exposed to the outside, with the cover140opened. The display unit150may be formed at a front surface of the housing110and may display the following on a screen: a date, a time, a measured blood sugar value, a blood sugar schedule notification message, and an abnormal blood sugar alarm message. The display unit150may be provided, for example, with a liquid crystal display (LCD) screen.

The selection button163may be provided to return to a previous menu or end a function after setting a variety of information.

When the blood sugar strip10is not connected with the blood sugar strip connector120, the blood sugar managing watch100may display such information as a current date and a current time through the display unit150like a basic operation of a general wrist watch. When the blood sugar strip10is connected with the blood sugar strip connector120, the blood sugar managing watch100may automatically switch from a general watch mode to a blood sugar measurement mode. In this case, the blood sugar meter130may execute a blood sugar measurement task to measure a blood sugar, and the measured blood sugar information may be displayed through the display unit150.

Even though the user does not operate the user interface unit160separately, the user may confirm a blood sugar value by inserting the blood sugar strip10into the blood sugar connector120and coat the blood sugar strip10with the gathered blood. Accordingly, this may make it possible that a user inexperienced to operate an electronic device easily measure a blood sugar. When blood sugar information is measured or when the blood sugar strip10is removed from the blood sugar strip connector120, the blood sugar measurement mode may be again switched to the general watch mode such that general watch functions such as a current date and time display, a stopwatch, and a notification are performed.

FIG. 4is a configuration diagram of a blood sugar managing watch according to an embodiment of the prevent invention, andFIG. 5is a sequence diagram illustrating a blood sugar managing method according to an embodiment of the prevent invention. In describing an embodiment illustrated inFIGS. 4 and 5, a duplicated description about components the same as or corresponding to an embodiment illustrated inFIGS. 1 and 3will be omitted. Referring toFIGS. 1 to 5, the blood sugar managing watch100may include the housing110, the blood sugar strip connector120, a sensing unit121, an interrupt handler122, the blood sugar meter130, a blood sugar measurement schedule management unit131, a memory132, the cover140, the display unit150, the user interface unit160, the connector170, a communication interface unit171, a communication module172, a state control unit173, a time measurement module180, a notification generation unit190, and a control unit200. A function of each component of the blood sugar managing watch100may be controlled by the control unit200.

The sensing unit121may be installed inside the housing110. The sensing unit121may detect that the blood sugar strip10is connected to the blood sugar strip connector120and may generate an interrupt event as the detection result. For example, when the blood sugar strip10is inserted into the blood sugar strip connector120, the end side of the blood sugar strip10may be connected to an electrode (not shown) inside the housing110, and thus a resistance or power value may be changed. At this time, the sensing unit121may recognize a change of a resistance or power value according to coupling of the blood sugar strip10and may detect that the blood sugar strip10is connected to the blood sugar strip connector120(S11). The sensing unit121may generate an interrupt event in detecting that the blood sugar strip10is connected to the blood sugar strip connector120(S12). The sensing unit121may be independent of the blood sugar strip connector120and may be integrated in the blood sugar strip connector120.

The interrupt handler122may be installed inside the housing110and may generate a signal (an activation control signal) for controlling to automatically activate a blood sugar measurement task at the blood sugar meter130based on the interrupt event generated from the sensing unit121. That is, under control of the interrupt handler122, a task of the blood sugar meter130may be selectively activated according to the interrupt event. In an embodiment, the interrupt handler122may count an interrupt frequency of the interrupt event; if the interrupt frequency is the same as a set value, the interrupt handler122may generate the activation control signal for operating the blood sugar meter130. If the interrupt frequency is not the same as the set value, a message indicating a device recognition error may be displayed on the display unit150. The activation control signal generated by the interrupt handler122may be inputted to the control unit200.

The control unit200may inactivate a graphical user interface (GUI) of a watch task in response to the activation control signal, may control the blood sugar meter130so as to execute a blood sugar measurement task, and may activate the GUI for blood sugar measurement (S14). If blood gathered from a human body is supplied on the blood sugar strip10(S15), the blood sugar meter130may execute a blood sugar measurement task to measure a blood sugar of the blood on the blood sugar strip10. For example, a current flowing on the blood sugar strip10changes according to the blood sugar, and the blood sugar meter130may measure a blood sugar by measuring a current value of the blood sugar strip10. Blood sugar measured by the blood sugar meter130may be stored by the control unit200in the memory132(S16).

In an embodiment, as illustrated inFIG. 6, the control unit200may configure blood sugar measurement data60by integrating an identifier (ID)61of the blood sugar managing watch100, a serial number62indicating a blood sugar measurement order, blood sugar information64measured by the blood sugar meter130, and information63of measurement time when the blood sugar information is measured in one data packet and may store the blood sugar measurement data60integrated in the single data packet in the memory132. As such, meaningful data in which private information and blood sugar information of a user is contained may be created by integrating a blood sugar managing watch ID, blood sugar information, and blood sugar measurement time information in one data packet and configuring data. The integrated data may be transmitted to a personal mobile terminal such as a smart phone or an external device such as a server terminal for a medical service, thereby making better use of data.

Referring again toFIGS. 1 to 5, the memory132may be, for example, a volatile memory such as a static RAM (SRAM), a dynamic RAM (DRAM), a synchronous DRAM (SDRAM), etc. or a nonvolatile memory such as a read only memory (ROM), a programmable ROM (PROM), an electrically programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM), a flash memory device, a phase-change RAM (PRAM), a magnetic RAM (MRAM), a resistive RAM (RRAM), a ferroelectric RAM (FRAM), etc.

The display unit150may display a blood sugar value analysis result on a screen. For example, a figure of a measured blood sugar value, a normal or abnormal state, a time when a blood sugar is measured, a time when a blood sugar is to be measured hereafter, etc. may be displayed on the display unit150(S17). If the measurement of a blood sugar is completed at the blood sugar meter130, a task of the blood sugar meter130may be inactivated (S18), and a watch GUI may be activated (S19).

The blood sugar measurement schedule management unit131may manage a list of schedules when a blood sugar is measured. As an embodiment, the blood sugar measurement schedule management unit131may transmit setting information in response to a setting information request message from a personal mobile terminal (a smart phone or etc.) of the user or an external device such as a hospital server or etc., may receive new setting information changed from the setting information from the external device, and may update the blood sugar measurement time based on the new setting information. A function of the blood sugar measurement schedule management unit131will be described with reference toFIG. 9.

The connector170may be installed on one side of an outer surface of the housing110and may be provided to be connected with a charger for charging a battery supplying a power to the blood sugar managing watch100, various sensors for measuring biosignals such as oxygen saturation, a pulse wave, and a heart rate, and a portable storage medium for storing blood sugar measurement data measured by the blood sugar meter130or copying or transferring the blood sugar measurement data stored in the blood sugar managing watch100.

The communication interface171may perform an interface function for transmitting and receiving various messages, signals, data, etc. between the blood sugar managing watch100and a device connected to the connector170. The communication interface171may support various devices and may be provided to support different communication protocols. The communication interface171may dynamically activate a communication protocol based on a device connected to the connector170and may perform communication based on the activated communication protocol.

As an embodiment, when a device is connected to the connector170, an interrupt event signal may be transferred to the interrupt handler122of the blood sugar managing watch100from the device connected to the connector170. The device connected to the connector170may generate the interrupt event signal having an interrupt frequency which is previously set for each device. Interrupt event signals with different interrupt frequencies may be transferred to the interrupt handler122based on a device connected to the connector170.

The interrupt handler122may count an interrupt frequency of the interrupt event signal. The control unit200may automatically recognize a communication protocol, which a device connected to the connector170supports, from among communication protocols supported by the communication interface171based on the interrupt frequency counted by the interrupt handler122and may control the communication interface171to activate a corresponding communication protocol. Accordingly, as a communication protocol of the communication interface171is dynamically activated according to various devices, it may be possible to set a communication network between a device and the blood sugar managing watch100automatically and in real time at the same time when the device is connected to the connector170.

The communication module172may be installed inside the housing110and may be a communication interface for transmitting data between a personal mobile terminal of a user or protector and an external device300(refer toFIG. 7) such as a hospital server. For example, the communication module172may perform functions of transmitting blood sugar measurement data measured by the blood sugar managing watch100to the external device300, receiving blood sugar measurement schedule update data from the external device300, sending a message indicating blood sugar non-measurement to a personal mobile terminal of a protector and the external device300when a user does not measure a blood sugar at a blood sugar measurement schedule, etc. The communication unit180may be implemented with a wireless communication device such as Bluetooth, BLE (Bluetooth Low Energy), an LF transceiver, an RF transceiver, or the like and may establish a wireless network between the blood sugar managing watch100and the external device300/400to transmit and receive data in a real-time streaming manner.

The blood sugar measurement data integrated in a single data packet structure may be transmitted between different external devices300and400. The first external device300may be a terminal performing bidirectional communication with the blood sugar managing watch100, for example, a mobile terminal such as a smart phone or a smart pad of a user or protector. The second external device400may be a terminal performing a hospital server function and may receive blood sugar measurement data from a terminal of a user or protector through a mobile web. However, blood sugar measurement data may be directly transmitted from the blood sugar managing watch110to the second external device400such as a hospital server, or it may be possible to update a blood sugar server and etc. of the blood sugar managing watch100by directly transmitting update information from the second external device400.

The state control unit173may activate or inactivate a wireless communication function of the communication module172in a predetermined period so as to minimize power consumption for wireless communication.FIG. 8is a sequence diagram illustrating a manner to transmit data between an external device and a blood sugar managing watch forming a blood sugar managing device according to an embodiment of the prevent invention. Referring toFIGS. 4 and 8, the control unit200of the blood sugar managing watch100may broadcast an advertising message, with a wireless communication function activated by the state control unit173.

For example, when a blood sugar management application is driven by a user, a protector, or a medical team on the external device300, the external device300may detect a surrounding signal to scan an advertising message. The external device300may transmit an advertising message input signal to the blood sugar managing watch100in response to the advertising message so as to be connected with a device, and in this process, a wireless network may be established between the blood sugar managing watch100and the external device300(S22). The external device300may transmit a blood sugar measurement data request message and order number information of blood sugar measurement data, which is lastly received in a previous communication process, to the blood sugar managing watch100(S23, S4). Based on the blood sugar measurement request message, the blood sugar managing watch100may transmit blood sugar measurement data, which is cumulated after a lastly transmitted order number, to the external device300by the single data packet (S25to S27).

As an embodiment, in the case where a wireless communication function is inactivated or in the case where wireless communication between the blood sugar managing watch100and the external device300is not established, for example, an advertising message input signal corresponding to the advertising message is not transmitted from the external device300even though a wireless communication function is activated, the control unit200of the blood sugar managing watch100may store blood sugar measurement data in the memory132in a delay tolerant manner; if a wireless network is established between the blood sugar managing watch100and the external device300, the blood sugar managing watch100may transmit the stored blood sugar measurement data, that is, blood sugar measurement data, in which the ID of the blood sugar managing watch100, blood sugar information, and blood sugar measurement time information are integrated, to the external device300. Accordingly, a user or a protector or medical team of the user may confirm blood sugar measurement data of the user through the external device300.

A blood sugar measurement value may be processed to one meaningful data by integration with the ID of the blood sugar managing watch and the blood sugar measurement time information, and the processed data may be transmitted to the external device300using a wireless communication function so as to be provided to the user or a protector or medical attendant. Accordingly, it may be possible to provide convenience in collecting medical measurement data. In addition, a medical service provider may classify blood sugar measurement data collected from a plurality of users through IDs of blood sugar watches for each user and may confirm blood sugar values about the users in a stream manner on the basis of time. The medical service provider may take measures, for example, may prescribe appropriate drug to a patient or may adjust a blood sugar management schedule.

The time measurement module180may be installed inside the housing110and may measure time information. In the case where the blood sugar strip10is removed from the blood sugar strip connector120, a watch task corresponding to a function of a general watch may be executed by the control unit200, and a date and a time which the time measurement module180recognizes may be displayed on the display unit150. If the blood sugar strip10is connected to the blood sugar strip connector120, a watch task may be inactivated, a blood sugar measurement task may initiate, and blood sugar measurement data measured by the blood sugar meter130may be displayed on the display unit150.

If a predetermined blood sugar measurement time arrives, the notification generation unit190may generate a notification indicating that the blood sugar measurement time arrives. Accordingly, a user may measure a blood sugar at an accurate time through a function of informing the user of a blood sugar measurement time. The notification generation unit190may include, for example, a vibration motor191generating a vibration or a speaker192generating a notification sound. For another example, the notification generation unit190may display a message on the display unit150or may notify a user that the blood sugar measurement time arrives, in another manner such as lighting of a notification lamp. Meanwhile, a program dedicated for blood sugar management is running on the external devices300and400such as a smart phone or a computer of a user, a protector, or a medical team, it may be possible to inform a blood sugar measurement time in manners such as a notification sound and a pop-up event at a corresponding external device300or400.

In an embodiment of the prevent invention, the blood sugar managing watch100may further include an alarm generation unit (not shown) which generates alarm when a blood sugar value measured by the blood sugar meter130is out of a threshold range. The alarm generation unit may notify a user that a blood sugar value is an abnormal numerical value, using a manner the same as or different from the alarm generation unit190. For example, in the case where a blood sugar value is out of a threshold range, the alarm generation unit may notify a user of dangerousness in a manner to light a red alarm lamp, in addition to a manner to display a dangerous situation through the display unit150or in a manner to generate an alarm sound through a speaker.

In the case where a blood sugar value is out of a normal range, the communication module172of the blood sugar managing watch100may transmit blood sugar management data and a message, which indicates an abnormal numerical value, to a terminal of a protector or such an external device as a hospital server or may transmit a character message, which indicates a dangerous situation, to a personal mobile terminal of a protector. In the case where a user does not measure a blood sugar at a set blood sugar measurement time, the communication module172of the blood sugar managing watch100may transmit a message (a blood sugar non-measurement notification message), which indicates that the user does not measure a blood sugar, to a terminal of a protector or such an external device as a hospital server or may transmit a character message (SMS, MMS, etc.), which provides notification that a blood sugar is not measured, to a personal mobile terminal of a protector.

FIG. 9is a diagram illustrating a sequence for updating a blood sugar measurement schedule by transmitting setting information between a blood sugar managing watch and an external device, according to an embodiment of the prevent invention. Referring toFIGS. 4 and 9, the blood sugar managing watch100may broadcast an advertising message (S31), and the external device300may transmit an advertising message input signal to the blood sugar managing watch100in response to the advertising message so as to be connected with a device (S32). If a setting information request message is transmitted from the external device300to the blood sugar managing watch100(S33), the blood sugar managing watch100may transmit setting information, which is currently set with regard to a blood sugar management schedule, in response to the setting information request message (S34).

Afterward, if a user, a protector, or a medical team changes a blood sugar measurement schedule from previous setting information to new setting information using the external device300(S35), the new setting information thus changed may be transmitted to the blood sugar managing watch100from the external device300(S36). The blood sugar managing watch100may update a blood sugar measurement schedule based on the new setting information received from the external device300(S37) and may display the updated schedule through the display unit150(S38). Finally, the blood sugar managing watch100may transmit a notification message, which indicates that the updating of setting information is completed, to the external device300(S39). An embodiment of the prevent invention is exemplified inFIG. 9as a blood sugar management schedule is updated through the external device300. However, it may be possible to update a blood sugar measurement schedule using the blood sugar managing watch100.

Blood sugar data may be confirmed on the blood sugar managing watch100by operating the menu button162of the user interface unit160or through the external device300or400, for example, through a dedicated program of a smart phone or computer.FIG. 10is a diagram illustrating the procedure for confirming blood sugar measurement data through a display unit of a blood sugar managing watch, according to an embodiment of the prevent invention. Referring toFIGS. 1 to 3 and 10, in the case where the blood sugar managing watch100operates in a watch mode in which a general watch task is performed, as illustrated in (a) ofFIG. 10, current date and time may be basically displayed on the display unit150.

If the blood sugar strip10is inserted into the blood sugar strip connector120, switching from a watch mode to a blood sugar measurement mode may be made. In this case, a blood sugar measurement task may be automatically activated at the blood sugar meter130, and a message such as “waiting for blood sugar measurement” may be displayed on the display unit150as illustrated in (b) ofFIG. 10. If the measurement of a blood sugar at the blood sugar meter130is completed, a measured value may be displayed on the display unit150as illustrated in (c) ofFIG. 10, and then the return to the watch mode illustrated in (a) ofFIG. 10may be made.

If a user pushes the menu button162in the watch mode, a menu list may be displayed on the display unit150as illustrated in (d) ofFIG. 10, and a cursor may be placed on a first item of the menu list, that is, such an item as “confirm a blood sugar value”. A cursor may move to another adjacent item whenever the menu button162is pushed. If the selection button163is inputted with a cursor placed on the item “confirm a blood sugar value”, a blood sugar value list may be displayed as illustrated in (e) ofFIG. 10. The blood sugar value list may include data and time information associated with the measurement of a blood sugar and blood sugar measurement values. A user may confirm a blood sugar value by moving a cursor using the menu button162, and the return to the menu list screen may be made if inputting the selection button163.

FIG. 11is a diagram illustrating the procedure for setting a blood sugar measurement time through a blood sugar managing watch, according to an embodiment of the prevent invention. As illustrated in (a) ofFIG. 11, if an item “set blood sugar measurement time” displayed on the display unit150is selected using the menu button162and the selection button163, a blood sugar measurement schedule list may be displayed as illustrated in (b) ofFIG. 11. At this time, after an item which is to be updated is selected from the blood sugar measurement schedule list, as illustrated in (c) to (e) ofFIG. 11, a blood sugar measurement schedule may be deleted or modified by selecting a delete or modify item, or the return to the blood sugar measurement schedule list may be made by selecting confirm. Meanwhile, in the case where a new blood sugar measurement schedule is added, an item “Empty” may be selected from a blood sugar measurement schedule list screen illustrated in (a) ofFIG. 12; after an item “add” is selected from a screen illustrated in (b) ofFIG. 12, information of a time when a blood sugar is to be measured may be inputted as illustrated in (c) to (e) ofFIG. 12.

The convenience in measuring a blood sugar may be provided by supporting the blood sugar meter130, which is embedded in the blood sugar managing watch100provided in a wrist watch shape and operates in conjunction therewith, to a patient suffering from a blood sugar disease as a chronic disease or a user interesting in personal health care. According to an embodiment of the prevent invention, all operations for blood sugar measurement and data transmission may be automatically performed only by connecting the blood sugar strip10to the blood sugar strip connector120and executing an application of the external device300or400, for example, a user smart phone, and an operation for performing a wireless communication function between the blood sugar managing watch100and an external device may be minimized. Accordingly, a user may measure a blood sugar easily and simply, and a user, such as an aged patient, unused to operate an electronic device may make it possible to collect blood sugar measurement data without any difficulty.

According to an embodiment of the prevent invention, an alarm may be generated to allow a user to measure a blood sugar on the basis of a set blood sugar measurement schedule, and corresponding information may be automatically notified to a user, a protector, or a medical team using a wireless transmission and reception function of the blood sugar managing watch100in the case where a measured blood sugar value corresponds to a dangerous numerical value or in the case where a user does not measure a blood sugar at a blood sugar measurement schedule. Accordingly, it may be possible to manage a blood sugar more thoroughly. This may mean that the diabetes and associated complications are prevented and that social costs due to the blood sugar disease are reduced.
