2 is a block diagram illustrating the general configuration of a drug injection device according to an embodiment.

The drug injection device 200 may include a housing 220 , a drug storage unit 230 , a driving unit 240 , a control unit 250 , and a notification unit 260 .

The header 221 of the housing 220 may be connectable to the needle part 210 . The header 221 may include a first fastening part that can be coupled to the needle part 210 . The drug injection device 200 may be connected to the needle part 210 through the first coupling part. The first fastening part is a structure that can be coupled to the second fastening part of the needle part 210 , and may be implemented as a fastening structure such as a screw-type structure and a magnet-type structure. For example, one of the first fastening portion and the second fastening portion includes a thread structure, and the other includes a thread groove structure, and the screw thread structure and the screw groove structure may be engaged with each other. can For another example, the magnets disposed in the first coupling part and the second coupling part may have different magnetisms, and each magnet may be implemented as a permanent magnet or an electromagnet. In addition, the header 221 of the housing 220 may include a first connector configured to receive an electrical signal associated with the target biological material from the needle unit 210 , and the first connector is the second connector of the needle unit 210 . It may be connectable with a connector. The first connector and the second connector may be electrically connected when the header 221 and the needle part 210 are coupled.

According to an embodiment, the header 221 may automatically separate the needle unit 210 used for measuring a target biological material and injecting a drug. For example, the header 221 may receive an error code from the needle unit 210 that has been used once, for example, through a connector. When the error code is received, the control unit 250 of the drug injection device 200 may separate the needle unit 210 from the header 221 . However, the present invention is not limited thereto, and when receiving an error code indicating that the needle unit 210 has already been used, the control unit 250 may prevent the measurement operation and the injection operation.

The needle part 210 may be connectable to the drug injection device 200 and may include a penetrating member and a second fastening part. The penetrating member is supported by the second fastening part, and one end (eg, the front end) of the penetrating member may be formed to be able to penetrate the skin, and the inside of the penetrating member is capable of moving a fluid along the longitudinal axis of the penetrating member. A passage may be formed.

The housing 220 may represent a member that supports or accommodates the drug storage unit 230 , the driving unit 240 , the control unit 250 , and the notification unit 260 . The housing 220 may be implemented as a pen-shaped structure in which the length is sufficiently longer than the width, or may be implemented as a box-shaped structure in which the difference between the length and the width is smaller than a critical length. The shape of the housing 220 may vary depending on the shape of the built-in drug storage unit 230 , the driving unit 240 , the control unit 250 , and the notification unit 260 .

The drug storage unit 230 is a member for storing a drug, and may accommodate a cartridge for storing the drug. When the needle unit 210 and the header 221 are connected, the drug storage unit 230 may be connected to the needle unit 210 and a drug delivery path may be formed. For example, the front end of the needle part 210 is exposed and extended from the fastening part of the needle part 210, and the distal end of the needle part 210 passes through the header 221 of the housing 220 to the drug storage unit ( 230) may be directly or indirectly connected. The drug storage unit 230 may deliver the drug to the needle unit 210 . For reference, the cartridge may be detached from the drug storage unit 230 . Accordingly, the user may mount the cartridge according to the doctor's prescription to the drug injection device 200 .

The driving unit 240 may be configured to apply an external force to the drug storage unit 230 . For example, the driving unit 240 applies an external force to the distal end of the drug storage unit 230, and the drug through the fluid path formed for the needle unit 210 from the front end of the drug storage unit 230. can be emitted.

The controller 250 measures the amount of the target biological material based on the electrical signal received through the first connector, determines the injection amount in response to the measurement being completed, and controls the driving unit 240 to inject the determined injection amount can do. For example, the controller 250 may sense an electrical signal indicating the amount of the target biological material through the connector, and determine the amount of the target biological material from the sensed electrical signal. The control unit 250 may discharge a precise amount of the drug from the drug storage unit 230 to the needle unit 210 by controlling the driving unit 240 .

The notification unit 260 may receive biometric information related to the amount of the target biomaterial and injection information related to the injection amount from the controller 250 and provide it to the user. The notification unit 260 may provide biometric information and injection information to the user by using various means. Furthermore, the notification unit 260 may also provide the user with drug information regarding the drug of the cartridge accommodated in the drug storage unit (230).

For example, the notification unit 260 may include a light emitting unit 261 , a display 262 , a sound output unit 263 , a vibrating unit 264 , and a communication unit 265 .

The light emitting unit 261 may include one or more light emitting devices. The number, arrangement, structure, and color of the light emitting devices may be designed in various ways. The light emitting unit 261 may include, for example, a light emitting diode (LED), a color of light emitted from the LED, a symbol indicated by the LED, and a method of blinking the LED (eg, the number of blinks) , length of time, etc.) may output content indicating the blood glucose level and the injection amount. The light emitting part 261 may be disposed on the outer peripheral surface of the housing 220 . The light emitting unit 261 may display drug information using at least one of a color, a combination of colors, a shape, a symbol, an arrangement, and blinking. For example, the light emitting unit 261 may output light of a color matching the color of the cartridge mounted on the drug injection device 200 . Accordingly, the user can insert the type of cartridge prescribed by the expert in advance into the drug injection device 200, and the drug injection device 200 emits the type of the inserted cartridge by the light emitting unit 261 as described above. The user can be guided intuitively through the color of the light. The light emitting unit 261 may include a plurality of light emitting devices disposed in a shape corresponding to a specific symbol or emit light having a shape corresponding to the specific symbol through masking formed in a shape corresponding to the specific symbol. Additionally, the light emitting unit 261 may perform a light emitting or blinking operation to provide a medication alarm and medication related information.

The display 262 may visualize drug information, biometric information, text information guiding injection information, and symbol information in a graphical representation. For example, the display 262 may visualize the type of drug, the dose of the drug, and the expiration date.

The sound output unit 263 may output a beep sound and a voice for guiding drug information, biometric information, and injection information. For example, the sound output unit 263 may output content indicative of the inserted drug type, cartridge information, measured blood glucose level, injection amount, and the like in the form of voice. For reference, when the needle unit 210 has already been used before, the control unit 250 may receive an error code from the needle unit 210, and the control unit 250 receives the error code in the form of a beep sound. As a result, a warning sound may be output through the sound output unit 263 .

The vibrator 264 may generate vibration for guiding biometric information, injection information, and drug information. For example, the vibrator 264 may vibrate the drug injection device 200 through a motor according to a drug injection alarm guiding the time of drug injection. For reference, since the occurrence of vibration during injection may pose a risk to the user, the vibrating unit 264 may generate vibration according to the drug injection alarm only when the cartridge is not mounted on the drug injection device. The drug injection time may be set by the controller 250 based on at least one of drug information and a degree of biometric measurement. Additionally, the vibrating unit 264 may provide a vibration corresponding to an alarm to remove the needle unit to the user after the injection is completed.

As another example, the vibrator 264 may vibrate with a vibration pattern determined based on biometric information, injection information, and drug information among a plurality of vibration patterns. In each of the vibration patterns, the intensity of vibration, the length of the vibration, the frequency of vibration, and the number of vibrations may be uniquely combined. For example, with respect to biometric information, a vibration pattern indicating a hypoglycemic state when the blood sugar level is lower than the hypoglycemia threshold, a vibration pattern indicating a hyperglycemic state when the blood sugar level exceeds the hyperglycemia threshold, and a blood sugar level within the normal range A vibration pattern indicative of a steady state may be assigned to each state.

The communication unit 265 may establish communication with an external device. For example, the communication unit 265 may establish wireless communication (eg, WiFi, Bluetooth, Zigbee, etc.) with the mobile terminal. The communication unit 265 may establish communication with the cloud server via the mobile terminal. The communication unit 265 may transmit biometric information, injection information, and drug information to or receive from an external device.

3 is a flowchart illustrating a method for guiding drug injection according to an embodiment.

First, in step 310 , the drug injection device may acquire drug information regarding a drug inserted into the drug injection device in response to a user operation. For example, the drug cartridge may be inserted by the user into the drug reservoir of the drug injection device. The drug injection device may acquire drug information before and after inserting the drug cartridge. The drug injection device may receive a drug information acquisition operation from the user at the time of inserting or exchanging the drug cartridge. For example, the drug injection device may recognize a code including information about the drug through the optical recognition unit. The user may place a label or the like on which a code corresponding to drug information is printed within the viewing angle of the optical recognition unit. The optical recognition unit may identify, for example, a barcode, a QR code, and a character code. The drug injection device may determine drug information corresponding to the recognized code. The drug injection device may retrieve drug information corresponding to the recognized code from an internal database or may receive it by requesting it from an external cloud server. The drug injection device may update an internal database regarding drug information through interworking with the mobile terminal.

In addition, the method of obtaining drug information is not limited to optical recognition. The drug injection device may receive a manual input (eg, an operation to indicate a specific drug) from the user, and may select a drug indicated by the manual input. As another example, in response to the mobile terminal receiving an input for selecting a drug from the user, the mobile terminal may transmit drug information about the corresponding drug to the drug injection device. The mobile terminal may receive a voice command from the user, and may select a drug based on a result of interpreting the received voice command.

And in step 320, the drug injection device may provide a drug injection alarm to the user at the drug injection time determined based on the drug information. The control unit of the drug injection device may determine an appropriate drug injection timing for the corresponding drug based on the drug information. For example, the drug injection device may determine a drug injection timing for the user based on previously measured biometric information (eg, blood sugar level) and prescribed drug information of the user. The drug injection device uses at least one of vibration, voice, color of the light emitting part, color combination, shape, symbol, arrangement, and blinking of the drug injection device to provide a drug injection alarm to the user in response to the arrival of the drug injection time. can be provided. For example, the drug injection device may vibrate the drug injection device at the time of drug injection. For another example, the drug injection device may play a voice alarm or beep sound at the time of drug injection. For another example, the drug injection device may emit or blink light corresponding to the color of the drug or cartridge through the light emitting element at the time of drug injection. For another example, the drug injection device may provide an alarm by utilizing the alarm API (Application Programming Interface) of the mobile terminal. Accordingly, the user can intuitively know when the drug should be injected without additional manipulation.

In addition, the drug injection alarm may indicate an operation of reproducing a pre-recorded voice. The mobile terminal may record and store an arbitrary voice from the user. The drug injection device or the mobile terminal may reproduce the recorded voice at the time of drug injection.

Subsequently, in step 330 , the drug injection device may output at least one of visual information, auditory information, and tactile information corresponding to the drug information in response to the user's confirmation request for the drug injection alarm is received. . The drug injection device may receive a confirmation request for the drug injection alarm from the user. For example, when an alarm sound is played as the drug injection alarm, the user may operate the drug injection device through the input interface to confirm the drug injection alarm. The input interface for confirming the drug injection alarm may be, for example, a button exposed to the outside of the housing, a touch display, and the like. The drug injection device may receive the user operation received after the drug injection alarm is provided as a request for confirmation of the drug injection alarm. The drug injection device is visual information, and the type of drug included in the drug information, the total dose of the drug, the remaining dose, the color of the drug, and the amount to be injected, such as the color of the light emitting part, the number of blinking of the light emitting part, the arrangement of the light emitting elements , and light emission time. In addition, the present invention is not limited thereto, and the drug injection device may visualize the drug information as a graphic object through the display.

Additionally, in response to a case in which a confirmation request is not received from the user until a predetermined time has elapsed from the drug injection time, the drug injection device may inform the user of the elapsed time from the drug injection time. For example, the drug injection device may provide a time elapsed from the time of drug injection to the user through an output interface (eg, a display, a sound output unit, etc.). The drug injection device may set a re-alarm according to a specific event after the drug injection time has elapsed. For example, the drug injection device sets a re-alarm time in response to a case in which a confirmation request is not received until a predetermined time elapses from the time of drug injection, and when the re-alarm time arrives, the drug injection alarm is reset to the user. can be provided to

In addition, after the drug injection is completed, the drug injection device may provide an alarm requesting the user to remove the needle unit. For example, the drug injection device may generate a vibration as an alarm instructing the user to detach the needle part in response to the drug injection being completed and the needle part being completely pulled out from the user's skin. In addition, the drug injection device may provide a cartridge replacement alarm in response to the lapse of a predetermined storage time after the cartridge is mounted. For another example, the drug injection device may provide a cartridge replacement alarm in response to a case in which the temperature at which the device is stored exceeds a predetermined storage temperature range.

4 is a view for explaining drug information according to an embodiment.

Drug information 410 according to an embodiment may represent information about a drug that can be stored in the drug injection device. For example, the drug may be contained within the cartridge 400, the cartridge 400 may be accommodated by the drug storage unit of the drug injection device. The drug information 410 includes the type of drug 420, total dose 430 of the drug, product serial number 440, expiration date 450, code 460, use of the drug, and storage temperature 470 of the drug. ) and the like. The drug information 410 may be provided by being printed on the tag associated with the cartridge 400 , a description, and the outer surface of a product box in which the cartridge 400 is packaged. However, this is a simple example, and the drug information 410 is not limited thereto.

For the cartridge 400 shown in FIG. 4 , the type 420 of the drug is insulin, the dose 430 is 3 mL, the serial number 440 is “XX…, and the expiration date 450 is “DD/MM” /YYYY", the code 460 is in the form of a QR code, and the storage temperature 470 is shown as room temperature. However, this is a simple example and is not limited thereto.

For reference, insulin manufacturers manufacture various types of insulin, and each manufacturer manufactures each of its products in a unique color. Therefore, the drug injection device can match the colors in a 1:1 ratio for each company's product. For example, when the drug injection device acquires drug information such as "Company A, fast-acting, 100 unit", the color corresponding to the drug is automatically displayed through the light emitting unit based on the data input in the key-value format. can

In addition, although the code 460 is illustrated as a QR code, it is not limited thereto, and may be a barcode or a character string code. As described below, the drug injection device may recognize the code 460 representing the drug information 410 through optical recognition. However, the acquisition of the drug information 410 is not limited to optical recognition.

The optical recognition unit 512 may recognize a code related to drug information in response to a user's manipulation. For example, the optical recognition unit 512 may optically recognize a code associated with drug information as described above with reference to FIG. 4 . The code may represent a serial number or string indicating the drug (eg, an Internet domain address representing information about the drug, etc.). By optically recognizing the code related to the drug through the optical recognition unit 512, the control unit may obtain drug information corresponding to the drug indicated by the recognized code. The control unit may obtain information about the color, type, and dose of the drug from the code.

For reference, it has been described herein that the color of the drug is identified from the code recognized by the optical recognition unit 512, but is not limited thereto. For example, the drug injection device 510 may optically determine the color of the drug stored in the cartridge accommodated in the drug storage unit through an additional sensor. The additional sensor may be a color sensor.

In addition, the drug injection device 510 according to an embodiment may allow only the use of a predetermined type of drug. For example, in response to the case that the drug recognized from the code does not conform to the predetermined drug, the controller may exclude drug information that does not conform to the predetermined drug. The drug injection device 510 may provide information that the cartridge of the drug that the user wants to mount on the drug injection device 510 is not compatible through the light emitting unit 511 and the sound output unit. The drug injection device 510 may prevent the use of incompatible drugs by excluding registration of drug information regarding incompatible drugs. The drug injection device 510 may receive an updated list of compatible drugs from the server.

The light emitting unit 511 may output biometric information and drug information under the control of the controller. As described above, the light emitting unit 511 may include a plurality of light emitting devices. The light emitting devices may be arranged to have various numbers and colors according to design.

According to an embodiment, the light emitting unit 511 may display drug information using at least one of a color of a light emitting device, a combination of colors of the light emitting devices, a shape, a symbol, an arrangement, and blinking. For example, the light emitting unit 511 may emit light of a color corresponding to the color of the drug.

For another example, the drug injection device 510 may acquire drug information by recognizing the chip mounted on the protective part of the cartridge, the shape of the protective part, and the color of the protective part.

The mobile terminal 620 may output a message received from the drug injection device 610 . For example, the mobile terminal 620 may output a voice signal to inject the drug together with the text at the time of drug injection. As another example, the mobile terminal 620 may output the biometric information received from the drug injection device 610 at the time when the biometric measurement is completed. However, this is an example, and the output method of each information is not limited thereto.

According to an embodiment, the drug injection device 610 may output at least one of visual information, auditory information, and tactile information corresponding to the biometric information in response to obtaining the biometric information. The biometric information may include, for example, an amount of a target biomaterial (eg, blood sugar level), a time at which the biometric information is measured, and a temperature. The drug injection device 610 may display light of a color corresponding to a range to which the value of the biometric information belongs among a plurality of ranges. For example, the drug injection device 610 may allocate the light of the first color to the first range, the light of the i-th color to the i-th range, and the light of the n-th color to the n-th range. n may be an integer of 1 or more, and i may be an integer of 1 or more and n or less. Each range may define a range of blood glucose level values. For example, the drug injection device 610 may allocate red light to the hypoglycemic range, may allocate yellow light to the hyperglycemic range, and may allocate blue light to the normal range. However, the allocation of colors is not limited thereto. The hypoglycemic range may represent a range in which a blood sugar level is lower than a hypoglycemic threshold, the high blood sugar range may represent a range in which the blood sugar level is higher than a hyperglycemic threshold, and the normal range may represent a range above the hypoglycemic threshold and below the hyperglycemic threshold. The hypoglycemia threshold and the high blood sugar threshold may be set differently for each individual user according to a doctor's prescription. However, the present invention is not limited thereto, and the hypoglycemic threshold and the hyperglycemic threshold may be set as default values according to general criteria.

Also, the drug injection device 610 may output voice guidance information corresponding to the biometric information. For example, the drug injection device 610 may reproduce a voice signal indicating a blood sugar level through the sound output unit.

Furthermore, the drug injection device 610 may output a voice signal instructing the administration guide based on the biometric information together with the drug information. For example, the drug injection device 610 may reproduce a voice signal related to a guide that a certain amount of a specific drug should be injected to the user at the time of drug injection through the sound output unit.

The drug injection device 610 may output visual information corresponding to the operation state currently being performed by the drug injection device 610 among the biometric operation state and the drug injection operation state. For example, the drug injection device 610 may visualize visual information (eg, a graphic object) indicating a biometric operation state through a display while measuring the biometric information through the needle unit. The drug injection device 610 may visualize visual information indicating a drug injection state through a display while injecting the drug in response to a user manipulation. However, the present invention is not limited thereto, and the drug injection device 610 may display an operating state through the light emitting unit 611 . For example, the drug injection device 610 may allocate a first color to the biometric operation state and allocate a second color to the drug injection operation state. The drug injection device 610 may emit light of a first color through the light emitting unit 611 while in the biometric operation state. In addition, the drug injection device 610 may emit light of the second color through the light emitting unit 611 while in the drug injection operation state.

7 is a view showing an example of outputting the drug injection progress of the drug injection device according to an embodiment.

According to an embodiment, while the drug injection device 710 performs the drug injection operation, the drug injection device 710 may provide the user with visual information corresponding to the current injection amount among the determined total injection amount.

For example, the cartridge 731 accommodated in the drug storage unit 730 in FIG. 7 may include a pusher 732 . In the drug injection device 710 , the piston 720 of the driving unit may be connected to or in contact with the pusher 732 . The drug injection device 710 may advance the pusher 732 by advancing the piston 720 through the driving unit. The drug injection device 710 may regulate the discharge of the drug by controlling the degree to which the pusher 732 is advanced (eg, a traveling distance). A light emitting unit 711 may be disposed on the outer surface of the drug injection device 710 , and the light emitting unit 711 may include a plurality of light emitting devices 741 , 742 , and 743 arranged in a row.

The drug injection device 710 may emit light through the number of light emitting elements 741 , 742 , and 743 corresponding to the current injection amount among the plurality of light emitting elements 741 , 742 , and 743 . In FIG. 7 , the drug injection device 710 may determine an injection amount of the drug based on the biometric information and the drug information. The drug injection device 710 may determine a forward distance of the pusher 732 or the piston 720 based on the determined injection amount. The drug injection device 710 may advance the pusher 732 of the cartridge 731 from the initial position 751 to the final position 753 according to the advance distance. As described above, the drug injection device 710 may advance the pusher 732 by advancing the piston 720 through the driving unit. The drug injection device 710 may emit light only from the light emitting device 741 corresponding to the initial injection degree among the plurality of light emitting devices 741 , 742 , and 743 at the initial position 751 . Then, during the operation of injecting the drug, the drug injection device 710 may determine the light emitting element 742 corresponding to the current injection amount according to the position 752 of the pusher 732 during injection. The drug injection device 710 may emit light to the light emitting devices 741 and 742 from the light emitting device 741 corresponding to the initial position 751 to the light emitting device 742 corresponding to the current injection amount. Accordingly, as the injection amount increases, the number of light-emitting elements that emit light may increase. Then, when the pusher 732 reaches the final position 753 , the drug injection device 710 emits light to all the light emitting elements 741 , 742 , 743 up to the light emitting element 743 corresponding to the final position 753 . By emitting , it is possible to indicate the completion of the injection operation.

However, this is a simple example, and the configuration for indicating the progress of drug injection is not limited thereto. For example, the drug injection device 710 may visualize a graphic object (eg, a bar shape) indicating a processing level corresponding to the current injection amount compared to the total injection amount through the display. . Furthermore, the drug injection device 710 may output the progress of the injection operation as a voice signal.

In addition, the drug discharge is not limited to controlling the forward distance of the pusher, and a discharge control unit may be disposed at the front end of the drug storage unit. In this case, the discharge control unit may control the amount of the drug discharged by an external force applied to the distal end of the drug storage unit.
