The disclosure relates to a blood glucose measurement device and method.
Diabetes has a major impact on the daily lives of patients. Diabetics should continually monitor their diet to maintain blood glucose balance and check whether insulin intake is appropriate for their diet. Currently, various portable devices for measuring blood glucose levels have been studied and developed. Typically, a blood glucose measurement device may measure a blood glucose value by collecting blood through a separately prepared needle and placing the blood on a sensor strip of the blood glucose measurement device. Recently, a blood glucose value is continuously measured by invasively inserting and fixedly attaching a needle-type sensor into a part of a human body. However, various embodiments described in the disclosure are not limited to such a blood glucose measurement device.
Recently, various application programs have been developed for patients to directly monitor changes in blood glucose values. For example, a patient may install a program to monitor a blood glucose value on a user terminal and record and check blood glucose values collected hourly. In addition, to perform monitoring tasks using the user terminal, communication between a blood glucose measurement device and the user terminal must be established, and thus, some blood glucose measurement devices are equipped with antennas for wireless communication.

According to an embodiment, the blood glucose measurement device 200 may further include a battery 270. The battery 270 may be electrically connected to at least some of the components of the blood glucose measurement device 200 and supply power to each component. The blood glucose measurement device 200 including the battery 270 may operate electrically even when not being electrically connected to an external power source. That is, the blood glucose measurement device 200 according to an embodiment may be used as a portable device.
According to an embodiment, the blood glucose measurement device 200 may include one or more switching elements 260. The switching element 260 according to an embodiment may include, for example, an operating switch and/or a transfer switch.
According to an embodiment, the operating switch refers to the switching element 260 for activating at least one component of the blood glucose measurement device 200. The operating switch may be controlled to a turn-on state or a turn-off state. The operating switch may connect two or more nodes in a circuit in the turn-on state and open two or more nodes in the turn-off state. For example, the operating switch may be electrically connected to the battery 270 to control the supply and cut-off of power. As another example, the operating switch may be electrically connected to the sensor system 240 to control the activation and inactivation of the sensor system 240. As another example, the operating switch may be electrically connected to the transceiver 230 to control activation or inactivation of a communication function.

A strip-type device 300b includes a space on one side of the housing thereof to accommodate a strip 390b, and blood glucose values may be obtained by applying blood to the strip 390b while the strip 390b is maintained in a state of being attached to the inside of the device.
According to an embodiment, the housing of the patch-type device 300a has one or more openings for receiving an external element (e.g., an introducer needle 395a) penetrating from the outside. The housing may include two openings through which an external element penetrates in a longitudinal direction, and the external element 395a may completely penetrate the patch-type device 300a by penetrating the two holes. Here, the external element 395a may penetrate the patch-type device 300a to introduce a sensor (e.g., the analyte sensor 390a) provided inside the device to the bottom of the skin.
According to an embodiment, the housing of the strip-type device 300b has one or more openings for accommodating an external element (e.g., the strip 390b). The housing may have one opening to accommodate the external element 390b in a longitudinal direction, and the external element 390b may be accommodated inside the housing and electrically coupled to the device. When blood is applied to one side of the strip 390b while the coupling between the device and the external element 390b is maintained, the device 300b may obtain a blood glucose value by analyzing components of the blood. In particular, according to an embodiment, the strip-type device 300b may include one or more control pads 380b.

According to operation S410, one or more processors may identify strip insertion (or penetration) based on an electrical signal generated by electrical coupling between a contact electrode and an external element. One or more electrodes for electrical coupling to the blood glucose measurement device may be provided in advance on one end of the strip. The one or more processors may identify that the strip has been inserted as one end of the strip is electrically coupled to the contact electrode of the housing of the blood glucose measurement device.
The one or more processors may obtain sensing information about blood applied on the strip while the strip is maintained in being inserted into the blood glucose measurement device. According to an embodiment, the sensing information is blood glucose measurement data (blood glucose data) obtained by one or more sensor systems provided in the blood glucose measurement device. For example, in the case of a strip-type device, a sensor system may include a strip and a sensor circuit electrically connected to the strip, and one or more processors may obtain sensing information about blood applied on the strip by using the sensor system. The sensing information obtained in this way may be output through a display module provided in the blood glucose measurement device or transmitted to a communicatively-connected external terminal.
According to operation S420, the one or more processors may switch the antenna module from an idle state to an active state in response to the identification of strip insertion. Here, the antenna module may be interchanged with a transceiver and may include, for example, an RF antenna, an NFC antenna, and a BT antenna, but is not limited thereto. The antenna module may be maintained in an open state with a battery until strip insertion is identified, and may be electrically coupled to the battery when strip insertion is identified. In other words, according to an embodiment, the one or more processors may operate one or more switching elements in response to identification of strip insertion, and the battery and the antenna module may be electrically coupled to each other as the one or more switching elements are operated. As such, the blood glucose measurement device according to an embodiment may electrically activate or inactivate the antenna module based on a coupling relationship between a strip and a contact electrode, thereby preventing battery power from being consumed by the antenna module in unnecessary situations.
According to operation S430, the one or more processors may request the external terminal for a text message by using the antenna module while the antenna module is supplied with power. Here, the term ‘request’ may be interchangeably used as a ‘request message’ or ‘a message including a request.’
According to an embodiment, the request transmitted to the external terminal may include one or more pieces of sensing information. Here, the sensing information refers to data related to a blood glucose value obtained by the sensor system. In addition, the request transmitted to the server may further include user information. The user information may further include display information of the blood glucose measurement device and the user's status information.
The status information may include various pieces of information related to the user. The status information may include at least one of eating statuses, meal times, and underlying diseases. The eating statuses may include, for example, a status before a meal and a status after a meal. The meal times may include, for example, breakfast, lunch, dinner, and before bedtime. The underlying diseases may include, for example, high blood pressure, low blood pressure, and diabetes. In this way, the various pieces of status information may be used when generating diagnostic information together with sensing information. The status information may be transmitted to the external terminal separately or together with the sensing information to generate diagnostic information.
Display information includes one or more preset parameters with respect to a method of outputting information through the display module. For example, the display information includes at least one of a text size, a font type, and a display dimension of the display on which a feedback message will be displayed. When the display information is included, the external terminal may modify at least a portion of the content of the feedback message that responds to the blood glucose measurement device based on the display information. For example, the external terminal may abbreviate or omit at least a portion of the content of the feedback message so that the feedback message may be entirely displayed on a single screen to fit the display dimension of the blood glucose measurement device. A detailed description is given below with reference to
According to an embodiment, a request for a feedback message may be transmitted to the external terminal in response to extraction or separation of the strip. The device may be set so that the request for the feedback message is not transmitted to the external terminal while the coupling between the strip and the device is maintained. The one or more processors may transmit the request for the feedback message to the external terminal by using the antenna module when electrical separation of the strip and the contact electrode is identified. The antenna module may be supplied with power in response to the identification of strip insertion, but power supply to the antenna module may be maintained for a certain period of time even when the strip is extracted or separated. However, when the certain period of time has elapsed, the one or more processors may switch the antenna module to an idle state or cut off power supply to the antenna module.
According to operation S440, the one or more processors may output the feedback message received from the external terminal on the display. The feedback message may include diagnostic information for the user. The user may easily determine an action related to health maintenance, such as visiting the hospital, by checking the feedback message.

According to operation S510, the one or more processors may supply power to the display module and the antenna module in response to the identification of strip insertion. A battery, the display module, and the antenna module may be maintained in an open state before the strip is inserted. The one or more processors may electrically couple the battery to the display module to supply power to the display module, in response to the identification of strip insertion. In addition, the one or more processors may electrically couple the battery to the antenna module to supply power to the antenna module, in response to the identification of strip insertion. In addition, power supply to the display module and the antenna module may also be performed simultaneously in response to the identification of strip insertion.
To distinguish between power supply and cut-off, one or more switching elements may be provided between the display module and the battery and/or between the antenna module and the battery. The one or more processors may determine whether to supply or cut off power by controlling the one or more switching elements.
According to an embodiment, the supply of power and the switching to an active state may be operationally separated. The one or more processors may output information through the display module while the display module is maintained in the active state. The one or more processors may transmit information through the antenna module while the antenna module is maintained in the active state.
The one or more processors may switch the display module and/or the antenna module between an idle state and an active state through one or more control commands while power supply is maintained. The one or more processors may switch the antenna module from the idle state to the active state in response to switching the display module from the idle state to the active state while power supply to the display module and/or the antenna module is maintained. In other words, the active state of the display module and the active state of the antenna module are operationally linked.

In addition, the one or more processors may supply power to the antenna module 630 at the same time as supplying power to the display module 650 or immediately after supplying power to the display module 650. Alternatively, when the display module 650 is switched from the idle state to the active state while power supply to the display module 650 is maintained, the one or more processors may supply power to the antenna module 630. The power supply may be performed, for example, by operating one or more switching elements. The one or more processors may switch the antenna module 630 from the idle state to the active state or from the active state to the idle state while power is supplied to the antenna module 630.
According to operation S530, the one or more processors may request the external terminal (e.g., a server) for a text message by using the antenna module while the antenna module is maintained in the active state. The request may include at least one of sensing data, status information, and display information as described above in operation S430.

According to operation S710, one or more processors of a blood glucose measurement device may control the antenna module to transmit a certain request in response to the extraction of strip outside the housing. The one or more processors may identify that the strip is extracted from the inside of the housing based on a change in electrical signals caused by an opening of an electrical coupling between one or more contact electrodes and the strip. When separation of the strip from the housing is identified, the one or more processors may control the antenna module to transmit a transmission request for a text message to the external terminal. The antenna module may be switched to an active state in response to insertion of a strip and may be maintained in the active state for a certain period of time even when the strip is separated from the housing. Alternatively, the antenna module may also be maintained in the active state until the display module is switched to an idle state or power supply to the display module is blocked even when the strip is separated from the housing. For reference, the term ‘extraction’ in the disclosure may be interchangeably used with ‘separation.’

According to operation S910, the blood glucose measurement device may request the external terminal for a text message by using an antenna module while power is supplied to the antenna module.
According to an embodiment, the request transmitted to the external terminal may include one or more pieces of sensing information. Here, the sensing information refers to data related to a blood glucose value obtained by the sensor system. In addition, the request transmitted to a server may further include user information. The user information may further include display information of the blood glucose measurement device and the user's status information.
The status information may include various pieces of information related to the user. The status information may include at least one of eating statuses, meal times, and underlying diseases. The eating statuses may include, for example, a status before a meal and a status after a meal. The meal times may include, for example, breakfast, lunch, dinner, and before bedtime. The underlying diseases may include, for example, high blood pressure, low blood pressure, and diabetes. In this way, the various pieces of status information may be used when generating diagnostic information together with sensing information. The status information may be transmitted to the external terminal separately or together with the sensing information to generate diagnostic information.
The display information includes one or more preset parameters with respect to a method of outputting information through the display module. For example, the display information includes at least one of a text size, a font type, and a display dimension of the display on which a feedback message will be displayed. When the display information is included, the external terminal may modify at least a portion of the content of the feedback message that responds to the blood glucose measurement device based on the display information. For example, the external terminal may abbreviate or omit at least a portion of the content of the feedback message so that the feedback message may be entirely displayed on a single screen to fit the display dimension of the blood glucose measurement device.
According to operation S920, the external terminal may search for the first message based on sensing information (e.g., the blood glucose data) and the user information. According to an embodiment, a plurality of text messages are recorded in a memory of the external terminal. The plurality of text messages may include or consist of a first text message group and a second text message group. The first text message group may include a message informing any one of normal blood glucose, high blood glucose, and low blood glucose. The second text message group includes a message informing that a blood glucose value is less than a minimum value of a target range by comparing the blood glucose value with the target range, a message informing that the blood glucose value is within the target range, and a message informing that the blood glucose value exceeds a maximum value of the target range.
According to an embodiment, the external terminal may select any one of messages in the first text message group and any one of messages in the second text message group based on the sensing information and a preset target range. The external terminal may generate a feedback message by combining the message selected from the first text message group and the message selected from the second text message group.
According to an embodiment, a first text message and a second text message may have different contents. According to an embodiment, when context information of the first text message does not match with context information of the second text message, the external terminal may correct the feedback message so that the context information of the first text message matches with the context information of the second text message. In a correction operation, the context information with respect to the second text message is set to have higher priority than the context information with respect to the first text message.
In addition, according to an embodiment, the request mentioned in operation S910 (or operation S430 of
The feedback message generated in this way may be transmitted from the external terminal to the blood glucose measurement device, stored in the memory of the blood glucose measurement device, and displayed through the display module of the blood glucose measurement device (operations S950 and S960).
A process of generating a feedback message based on a network communication between a blood glucose measurement device and an external terminal is described above. However, the antenna module of the blood glucose measurement device is not always maintained in an active state, and in some cases, the network connection may be unstable, and thus a feedback message may not be received or a request for the feedback message may not be transmitted. Hereinafter, a method of requesting a feedback message adaptively to a network environment is described with reference to

In the case of a strip-type device, the sensing information may be obtained once per strip. The sensing information stored in the memory is transmitted to the external terminal whenever a strip is removed from the blood glucose measurement device, and the transmitted sensing information is excluded from the memory, and thus the sensing information is not typically accumulated. However, when the sensing information may not be transmitted to the external terminal, the sensing information that failed transmission may remain recorded in the memory, and as a result, a plurality of pieces of sensing information may be stored in the memory.
In the case of a patch-type device, the sensing information may be continuously or periodically obtained while the blood glucose measurement device is attached to the body. Accordingly, a plurality of pieces of sensing information may be stored in a memory.
According to an embodiment, the sensing information may be transmitted to the external terminal in response to removal of an external element (e.g., a strip). According to another embodiment, the sensing information may also be transmitted to the external terminal based on an operation of the display module. For example, the sensing information may be transmitted to the external terminal based on the switching of the display module from an idle state to an active state. As another example, the sensing information may also be transmitted based on switching of a user interface representation being displayed on the display module. An operation of transmitting sensing information based on switching of a user interface representation is described below with reference to

In the above embodiment, the second sensing information may be understood as sensing information obtained at a time point adjacent to a time point at which transmission of a request was triggered most recently. In the above embodiment, the first sensing information may be understood as one or more pieces of sensing information obtained temporally prior to the second sensing information, and the first sensing information may include or consist of one or two or more pieces of sensing information.
In some embodiments, when a plurality of pieces of sensing information is stored in the memory, the sensing information transmitted to the external terminal may be determined by selecting at least some of the plurality of pieces of sensing information. For example, the blood glucose measurement device may select and transmit at least some of the plurality of pieces of sensing information, the at least some of the plurality of pieces of sensing information, which is transmitted, may be excluded from the memory, and sensing information, which is not transmitted, may be maintained in a recorded state in the memory. According to an embodiment, the sensing information to be transmitted to the external terminal may be determined based on at least one of an obtaining time of blood glucose information or a transmission status whether to transmit the sensing information. The obtaining time refers to a time at which sensing information is obtained. The transmission status is information indicating whether to transmit sensing information. Sensing information already transmitted to the external terminal may be classified as ‘transmitted,’ and sensing information that has no history of being transmitted to the external terminal may be classified as ‘non-transmitted.’
According to an additional embodiment, at least a portion of sensing information transmitted to the external terminal will be deleted from the memory, but the remaining portion thereof remains in the memory based on a certain condition. As such, the sensing information that remains recorded in the memory may be coupled to a tag indicating already transmitted information to be distinguished from non-transmitted sensing information. Here, the certain condition may include a time condition and a number condition of the sensing information. The time condition is related to a time at which sensing information is obtained, and sensing information within a certain time range from a date on which the sensing information is obtained may be maintained in the memory even after being transmitted to the external terminal. The number condition is the minimum number of pieces of sensing information to be remained in the memory. For example, when the number condition is set to 2, at least two pieces of sensing information should be recorded in the memory. In this case, at least some pieces of sensing information that have already been transmitted are maintained in the memory in a state of being coupled to a tag so that the minimum number of pieces of sensing information may be maintained in the memory even after the sensing information is transmitted to the external terminal.

In some embodiments, transmission of sensing information stored in the memory may also be performed based on a particular user input. When the particular user input is received, one or more processors of the device may transmit sensing information to the external terminal by using the antenna module regardless of whether a user interface representation is switched, whether an external element is inserted/removed, and a state of the display module. The particular user input may be received through a control pad and/or touch screen pad provided on the blood glucose measurement device.

The blood glucose measurement device may transmit at least some pieces of the first and second sensing information and/or the first and second user information to the external terminal to generate a feedback message. For example, the blood glucose measurement device may select and transmit the first sensing information and the first user information related to the first sensing information to the external terminal, or may select and transmit the second sensing information and the second user information related to the second sensing information to the external terminal. At the same time or immediately thereafter, the blood glucose measurement device may request the external terminal for generation of a feedback message.
The blood glucose measurement device according to an embodiment may supply power to another component, cut off power, or switch the other component to an active state based on insertion and separation of an external element, such as a strip.
In particular, the blood glucose measurement device according to an embodiment may include a touch screen panel for receiving a user's electrostatic touch input or a control pad for receiving a physical key input of the user. The blood glucose measurement device according to an embodiment distinguishes a first interaction input through the touch screen panel and/or the control pad from a second interaction electrically coupled to an external element to display different user interface representations. As such, the blood glucose measurement device according to an embodiment may provide a user-friendly user interface environment by displaying different user interface representations based on an interaction routes, and a process of switching a user interface representation is dividedly described according to types of interactions with reference to

According to an embodiment, the blood glucose measurement device may switch an antenna module from an idle state to an active state before, simultaneously with, or immediately after the sixth user interface representation is displayed on the display. According to an embodiment, the blood glucose measurement device may switch the antenna module from the idle state to the active state in response to display of the fifth user interface representation on the display. In some embodiments, the antenna module may be switched to the active state in response to insertion of the external element or may be switched to the active state in response to switching of a display module to an active state. However, to further efficiently manage power consumption for the antenna module, the switching of the antenna module to the active state may also be performed based on switching of user interface representation. The antenna module may be maintained in the idle state until sensing information (e.g., a blood glucose value) is displayed through the fifth user interface representation, and the antenna module may be switched to the active state in response to display of the fifth user interface representation.
When the external element is separated and removed from the blood glucose measurement device while the antenna module is maintained in the active state, the fifth user interface representation is changed to a sixth user interface representation, and the sixth user interface representation is displayed. The sixth user interface representation may include or consist of an animation or icon indicating transmission of a message. The blood glucose measurement device may change the sixth user interface representation to a seventh user interface representation and display the seventh user interface representation in response to completion of transmission of a message, that is, a request for a feedback message. The seventh user interface representation includes at least a portion of a feedback message received from the external terminal. The feedback message may be generated based on sensing information, user information, and/or display information, which is transmitted to the external terminal. The feedback message may include or consist of diagnostic information generated based on one or more pieces of information included in the request.
