The file distribution server may be a server included in the server (100), but may also be a separate server linked to the server (100) as a third-party server.
[0027] FIG. 2 is a schematic diagram of an LED phototherapy device control system using artificial intelligence according to one embodiment of the present invention. Referring to FIG. 2, the LED phototherapy device control system using artificial intelligence according to one embodiment of the present invention includes a user terminal (300) and an LED phototherapy device (400).
[0028] The LED phototherapy device (400) includes an LED pad (410) and an LED control module (420). The LED pad (410) is configured in a form in which an LED module in which a plurality of LED elements are arranged in a certain pattern on a printed circuit board is mounted on the pad.
[0029] The LED control module (420) controls the operation of the LED module and includes a microcontroller such as an MCU. The LED control module (420) can be connected to the LED module via a wire or wireless connection. Meanwhile, the LED control module (420) can include a UI (User Interface) means such as a button or a touch panel display. The user can select a desired menu or mode using the button or touch panel provided on the LED control module (420) and receive light therapy using the LED pad (410).

[0032] The memory (310) is a recording medium readable by a computing device, and can store at least one computer program code and data executed by the processor (320). The computer program code can also be loaded into the memory (310) from a floppy drive, disk, tape, DVD / CD-ROM drive, memory card, etc. separate from the memory (310).
[0033] The processor (320) is intended to execute and process computer program instructions by performing basic logic, calculations, operations, etc., and the computer program code stored in the memory (310) is loaded into the processor (320) and executed. The processor (320) executes a user application stored in the memory (310) to perform a series of functions for controlling the LED phototherapy device.
[0034] The memory (310) includes a data table storing clinical information according to a disease. In one example, the data table is constructed on the server (100), and at least a portion of the data table may be provided to the user terminal (300). In another example, the data table regarding the aforementioned clinical information may be constructed on the user terminal (300). A series of processes, such as online clinical paper data collection and extraction, for constructing the data table may be performed by a user application. The user application includes an AI analysis module for processing a series of processes, such as clinical paper data collection and extraction. To avoid redundant description, a detailed description will be replaced with a description regarding the server (100) described above.
[0035] The memory (310) includes a control value calculation model for calculating the control value of the LED module according to the patient. The control value calculation model is provided by the server (100) and stored in the memory (310), and the processor (320) calculates the control value of the LED module according to a preset logic based on clinical information constructed as a data table using the control value calculation model. The control value calculation model stored in the user terminal (300) may be updated by the server (100) periodically or at any time as needed.
[0036] As illustrated in FIG. 1, a user terminal (300) according to one embodiment of the present invention may further include a display (330) for displaying data and images, a user interface (340) for receiving user input, and a communication interface (350) for linking with the outside.
[0037] Below, a method for controlling an LED phototherapy device using artificial intelligence according to one embodiment of the present invention will be described. Any descriptions that overlap with the previously described embodiment will be omitted as necessary.
[0038] First, the user accesses the file distribution server or server (100) via the user terminal (300), downloads and installs the user application according to the present invention, and then executes it. First, the user can register as a member, and when registering as a member, the user can register information such as gender, age, disease, and symptom severity. At this time, multiple users can be registered in the application installed on one user terminal (300). The user application installed on the user terminal (300) includes a control value calculation model of the LED phototherapy device (400) and can be updated by the server (100) periodically or at any time.
[0039] Figure 4 is a flowchart of a method for controlling an LED phototherapy device (400) using artificial intelligence according to one embodiment of the present invention.
[0040] The user terminal (300) (user application) collects clinical research papers on LED phototherapy online (S11). The user application can be configured to periodically search specific sites and extract relevant clinical research papers.
[0041] The user terminal (300) (user application) extracts data on at least four first clinical items among disease, body part, symptom level, age, gender, number of clinical patients, and treatment effect from the collected clinical paper data, and at least four second clinical items among wavelength, frequency, peak power, duty ratio, operating time, and treatment interval of the LED module (S12).
[0042] As mentioned above, the first clinical item is patient-related information, and the second clinical information is information regarding LED module control values related to treatment. The user application includes an AI analysis module for collecting and extracting data from these clinical papers, and can be configured to perform operations periodically or intermittently.
[0043] The user terminal (300) (user application) builds data on the extracted first clinical item and second clinical item into a data table and stores it in the memory (310) (S12).
[0044] Table 1 below illustrates an example of a data table regarding clinical information according to one embodiment of the present invention.
[0045] Disease nameBody partSymptom severity (1-10)Age groupGender (male and female)Number of clinical patientsWavelengthLED powerDuty ratioFreq.Operation timeIntervalTreatment effect e n (1~5) Note (LED / laser) 1 Alzheimer's 1 Head 450F12W1P1D1F1T 11 times / 1 day 3… 2 Alzheimer's 2640M50W2P2D2F2T 21 times / 2 days 4… 3 Alzheimer's 3860F3W3P3D3F3T 31 times / 3 times 5… 4 Cognitive Impairment 1… … … … … … … … … … … … 5 Cognitive Impairment 2… … … … … … … … … … … … … 6… … ...
[0046] As shown in Table 1 above, clinical data corresponding to each clinical item is extracted from clinical paper data and prepared as a data table. In the above-described embodiment, steps S10 to S12 were described as being performed by the user terminal (300), but according to another embodiment of the present invention, they may be performed by the server (100). In the latter case, the server (100) provides the data table to the user terminal (300), and the user terminal (300) stores the data table in the memory (310) so that it can be used to calculate driving variable values later.
[0047] When a user wishes to receive treatment using an LED light therapy device (400), the user logs in by executing the user application installed on the user terminal (300), and the user application creates a first UI for a questionnaire for the user and displays it on the display (S13).
[0048] The first UI includes items related to the user's age (age), gender, disease name, body part, and symptom severity. If the user enters information regarding all or part of the items during membership registration, the questionnaire regarding the previously entered information may be omitted. In addition, since, for example, the symptom severity is a value that changes depending on treatment, the user application may display the previously entered information in the first UI when the user uses the LED light therapy device (400), allowing the user to edit only the items they wish to edit.
[0049] The first UI may further include an item asking whether the user has a condition such as cancer or pregnancy. If the user selects "Yes" in this item, use of the LED phototherapy device (400) may be restricted. As another example, if the user has multiple diseases, the user may enter and register each disease individually.
[0050] The user application calculates the operating variable values of the LED module based on the information entered through the first UI and the data table (S14). Here, the operating variables of the LED module include at least four of the wavelength (or frequency), peak power, duty cycle, operating time, and treatment interval of the LED module.
[0051] The method for calculating the operating variable values of the LED module of the user application will be described later. Generally, the operating variable values of the LED module used in the phototherapy device are limited to a certain range. In this embodiment, the wavelength of the LED module: 660 nm, 850 nm, 940 nm, LED emission power: P min ~ P max (0 ~ 15 mW), Duty Ratio: 0 ~ 100%, Driving Frequency: F min ~ F max (0 ~ 5 kHz), operating time: T min ~ T max Here is an example of setting it to (0 to 15 minutes).
[0052] The user application identifies a clinical case in the data table that has data for the first clinical item that matches the information entered through the first UI. Then, based on the data for the second clinical item of the identified clinical case, it calculates the operating parameter values of the LED module.
[0053] For example, if a user inputs the disease name as 'Alzheimer', the body part as 'head', the age as '60s', the gender as 'female', and the symptom severity as '6' in Table 1, the user application extracts clinical cases with matching values for the corresponding items from the data table. For example, if there are three matching clinical cases, the user application calculates the operating variable value of the LED module based on the data of the second clinical item (LED operating variable) of the three clinical cases.
[0054] Specifically, the driving variable value is calculated by assigning a weight to the data of the second clinical items of clinical cases having data of the first clinical item matching the information entered through the first UI based on at least one of the value of the number of clinical subjects and the value of the treatment effect. For example, the final LED driving variable value is calculated by assigning a higher weight to the second clinical item (LED driving variable) of a clinical case with a large number of clinical subjects and / or a clinical case with a high treatment effect.
[0055] In one example of the present invention, the peak power (P) of the LED module can be calculated by the following formula.
[0056]
[0057] Here, P represents the peak power value of the clinical case matching the user's questionnaire entry in the data table, and e represents a weighting factor, assigned a value from 1 to 5 based on the number of clinical trial participants and the treatment effect of the matching clinical case (the minimum value is 1). For example, a higher value can be assigned to a higher number of clinical trial participants, and a higher value can be assigned to a higher treatment effect.
[0058] The user application determines whether the calculated P value is outside the specification range of the LED phototherapy device (400) as shown below, and then determines the final power peak value.
[0059] For example, (i) P min ≤ P ≤ P max If , the calculated P value is determined as the final power peak value, and (ii) P < P min If P min The value is determined as the final power peak value, (iii) P max If < P then P max is determined as the final power peak value.
[0060] In one example of the present invention, the duty ratio (D) of the LED module can be calculated by the following formula.
[0061]
[0062] Here, D represents the duty ratio value of the clinical case matching the user's questionnaire entry in the data table, and e represents a weight, assigned a value between 1 and 5 based on the number of clinical trial participants and the treatment effect of the matching clinical case in the data table. For example, a higher value can be assigned as the number of clinical trial participants increases, and a higher value can be assigned as the treatment effect increases.
[0063] In one example of the present invention, the driving frequency (F) of the LED module can be calculated by the following formula.
[0064]
[0065] Here, F represents the driving frequency value of the clinical case matching the user's questionnaire entry in the data table, and e represents a weighting factor, assigned a value between 1 and 5 based on the number of clinical trial participants and the treatment effect of the matching clinical case in the data table. For example, a higher value can be assigned as the number of clinical trial participants increases, and a higher value can be assigned as the treatment effect increases.
[0066] The user application determines whether the generated F value is outside the specification range of the LED phototherapy device (400) as shown below, and then determines the final driving frequency value.
[0067] For example, (i) F min ≤ F ≤ F max In this case, the calculated F value is determined as the final driving frequency value, and (ii) F < F min If F min The value is determined as the final driving frequency value, (iii) F max F if < F max is determined as the final driving frequency value.
[0068] In one example of the present invention, the operating time (T) of the LED module can be calculated using the following formula.
[0069]
[0070] Here, T represents the operating time value of the clinical case matching the information entered by the user in the questionnaire in the data table, and e is a weight, assigned a value ranging from 1 to 5 based on the number of clinical trial participants and the treatment effect of the matching clinical case in the data table. For example, a higher value can be assigned as the number of clinical trial participants increases, and a higher value can be assigned as the treatment effect increases.
[0071] The user application determines whether the produced T value is outside the specification range of the LED phototherapy device (400) as shown below, and then determines the final operating time value.
[0072] For example, (i) T min ≤ T ≤ T max If , the calculated T value is determined as the final operating time value, and (ii) T < T min If T min The value is determined as the final operating time value, and (iii) T max If < T then T max is determined as the final operation time value.
[0073] The user terminal (300) (user application) transmits the operating variable values of the LED control module (420) calculated through the aforementioned process, for example, values related to the wavelength, frequency, peak power, duty ratio, operating time, and treatment interval of the LED module, to the LED control module (420) (S15). The LED control module (420) controls the operation of the LED module according to the LED operating variable values received through the user terminal (300).
[0074] In this way, the present invention controls the operation of the LED phototherapy device (400) with an operating variable value that has an optimal treatment effect based on clinical information that matches information such as disease, body part, age, gender, and symptom level entered by the user, thereby enabling the user to receive treatment under optimal conditions.
[0075] Upon completion of treatment, the user application generates a second UI regarding treatment satisfaction and displays it on the display (S16). Furthermore, it generates and displays a graph showing changes in data entered by the user regarding symptom severity and treatment satisfaction over time (S17).
[0076] Figure 5 is an example of a graph showing symptoms and satisfaction levels displayed in a user application for controlling an LED phototherapy device (400) using artificial intelligence according to one embodiment of the present invention. As illustrated in Figure 5, by displaying the treatment progress over time at a glance, the user can check how symptoms or satisfaction levels have changed during the treatment period.
[0077] The present invention can also be implemented in various computer-readable recording media, such as magnetic storage media, optical reading media, and digital storage media, which store a computer program for performing the control method of the LED phototherapy device (400) according to the present invention when executed on a computer. In addition, the description expressed as steps in the claims is not limited to the order of the steps.
[0078] While several embodiments of the present invention have been described so far, those skilled in the art will appreciate that modifications or substitutions of certain embodiments may be made without departing from the technical spirit of the present invention. Therefore, the scope of protection of the present invention should be deemed to encompass the inventions described in the claims and their equivalents.
