In automatic shooting mode, the wearable terminal device 10 generates a 2D image and a depth image.

[0031] The image generation unit 103 generates two-dimensional images and depth images of the pressure ulcer. Specifically, the image generation unit 103 causes the camera 16 to perform an imaging process to generate a two-dimensional image of the pressure ulcer.

[0035] Figure 5 shows an example of the functional configuration of the information processing device 20 according to this disclosure. The information processing device 20 includes a receiving unit 200, a pressure ulcer detection unit 201, a pressure ulcer detection model 202, a depth calculation unit 203, a depth calculation model 204, a size calculation unit 205, a size calculation model 206, a superimposed image generation unit 207, a voice information analysis unit 208, a voice information analysis model 209, a patient information extraction unit 210, a patient information extraction model 211, and a transmission unit 212.

[0036] The receiving unit 200 receives various information from other devices. The information received by the receiving unit 200 includes 2D captured images, depth images, and measurement information transmitted by the wearable terminal device 10.

[0037] The pressure ulcer detection unit 201 detects pressure ulcers from 2D captured images and depth images using the pressure ulcer detection model 202.

[0038] The pressure ulcer detection model 202 is a machine learning model that detects pressure ulcers contained in 2D captured images and depth images. When a 2D captured image and depth image containing pressure ulcers are input to the pressure ulcer detection model 202, it is trained to output coordinate information that defines the image region of the pressure ulcer in each of these images. The pressure ulcer detection model 202 can be trained using machine learning methods such as deep learning.

[0039] The depth calculation unit 203 uses the depth calculation model 204 to calculate the depth of a pressure ulcer from the depth image in which the pressure ulcer was detected by the pressure ulcer detection unit 201.

[0040] The depth calculation model 204 is a machine learning model that calculates the depth of a pressure ulcer from a depth image in which a pressure ulcer has been detected by the pressure ulcer detection unit 201. The depth calculation model 204 can be trained using machine learning such as deep learning. When the depth calculation model 204 receives a depth image containing a pressure ulcer and coordinate information defining the image region of the pressure ulcer, it is trained to output the depth information of the pressure ulcer contained within the image region of the pressure ulcer. For example, if the image region of the pressure ulcer is displayed as a rectangle, the coordinate information defining the image region of the pressure ulcer can be the coordinates of the edges of that rectangle.

[0041] The size calculation unit 205 uses the size calculation model 206 to calculate the size of a pressure ulcer from a two-dimensional captured image in which a pressure ulcer has been detected by the pressure ulcer detection unit 201. The size of the pressure ulcer is, for example, the longest and shortest diameters of the pressure ulcer.

[0042] The size calculation model 206 is a machine learning model optimized to calculate the size of a pressure ulcer from a two-dimensional captured image in which a pressure ulcer has been detected by the pressure ulcer detection unit 201. The size calculation model 206 can be trained using machine learning such as deep learning. When the size calculation model 206 receives a two-dimensional captured image containing a pressure ulcer, coordinate information defining the image region of the pressure ulcer, the size of the image region of the pressure ulcer, and distance information provided by the wearable terminal device 10 as input, it is trained to output the size of the pressure ulcer contained in the image region. The size of the image region of the pressure ulcer is the size of the image region in which the pressure ulcer is displayed and can be expressed in pixels. The distance information provided by the wearable terminal device 10 represents the distance from the distance measuring sensor 17 to the pressure ulcer. Based on the correspondence between this distance information and the size of the image region in which the pressure ulcer is displayed, the size calculation model 206 can calculate the size of the pressure ulcer contained in the image region.

[0043] The superimposed image generation unit 207 generates a superimposed image 50 by superimposing predetermined image objects 52 and 53 onto the two-dimensional captured image 51. Figure 10 shows an example of a superimposed image 50 of a pressure ulcer generated by the superimposed image generation unit 207. The superimposed image 50 of the pressure ulcer includes an image object 52 indicating focus and an image object 53 indicating scale. The superimposed image generation unit 207 can superimpose an image object 53 corresponding to the size of the pressure ulcer calculated by the size calculation unit 205 onto the two-dimensional captured image 51. The image object 53 indicating scale can represent any unit of length such as millimeters, centimeters, or inches.

[0044] The voice information analysis unit 208 analyzes the voice information provided from the wearable terminal device 10 using the voice information analysis model 209.

[0045] The speech information analysis model 209 is a machine learning model that analyzes speech information provided by the wearable terminal device 10 and outputs text information contained in the speech information. In this embodiment, a pre-trained model capable of speech recognition can be used as the speech information analysis model 209. The speech information analysis model 209 can be trained using training data in which speech information including various human conversations is used as input information and text information representing those conversations in text is used as output information.

[0046] The patient information extraction unit 210 uses the patient information extraction model 211 to extract patient information, which is information about the patient, from the text information output by the voice information analysis unit 208. The patient information includes information about the patient's pressure ulcers.

[0047] The patient information extraction model 211 is a machine learning model that extracts patient information from text information output by the speech information analysis model 209. In this embodiment, a language model such as a Large Language Model (LLM) can be used as the patient information extraction model 211. The patient information extraction model 211 is trained to output text information that summarizes the content of the text information when text information is input. Figure 12 shows an example of text information extraction by the patient information extraction model 211. When text information 60 is input, the patient information extraction model 211 can output text information 61 that summarizes the content of the text information. The text information 61 corresponds to patient information.

[0048] The transmitting unit 212 transmits various information to other devices. The information transmitted by the transmitting unit 212 includes identification information for superimposed images, depth information, size information, and pressure ulcer information, which are sent to the wearable terminal device 10. When the transmitting unit 212 transmits this information to the wearable terminal device 10, it registers predetermined information in the transmission history table where transmission history information is registered. Figure 6 shows an example of the transmission history table. The transmission history table registers the identification information of the wearable terminal device 10 to which the superimposed images etc. are sent (terminal device ID: Identification), the identification information of the pressure ulcer information which is the identification information of the transmitted depth information and size information (pressure ulcer information ID), the identification information of the transmitted superimposed image (image ID), and the transmission date and time in association with each other.

[0049] Furthermore, the information transmitted by the transmission unit 212 includes patient information extracted by the patient information extraction unit 210, which is then sent to the electronic medical record management device 30. Along with the patient information extracted by the patient information extraction unit 210, the transmission unit 212 also transmits patient identification information (patient ID). The patient ID is provided by the wearable terminal device 10.

[0050] Figure 7 shows an example of the functional configuration of the electronic medical record management device 30 according to this disclosure. The electronic medical record management device 30 includes a receiving unit 300, a registration unit 301, and a patient information storage unit 302.

[0051] The receiving unit 300 receives various information from other devices. The information received by the receiving unit 300 includes the patient ID, superimposed image of the pressure ulcer, pressure ulcer depth information, pressure ulcer size information, and patient information transmitted by the information processing device 20.

[0052] The registration unit 301 registers the superimposed image of the pressure ulcer, the depth information of the pressure ulcer, the size information of the pressure ulcer, and the identification information of the patient, transmitted by the information processing device 20, in the electronic medical record information table, associating them with the patient ID.

[0053] The patient information storage unit 302 stores the patient information transmitted by the information processing device 20 in the patient information database. The patient information database can be built on the storage device of the electronic medical record management device 30.

[0054] Figure 8 shows an example of an electronic medical record information table. The electronic medical record information table registers patient ID, patient name, patient admission date, patient hospital room, patient date of birth, patient age, pressure ulcer depth, pressure ulcer long and short diameters, last update date and time, image ID, patient information ID, etc. The last update date and time is the last update date and time of the electronic medical record information table. The image ID is the identification information of the superimposed image. The patient information ID is the identification information of the patient information stored in the patient information database.

[0055] Figure 9 is a sequence diagram showing an example of the process performed in the pressure ulcer recording support system 1. In step S1, the instruction receiving unit 101 of the wearable terminal device 10 receives an instruction from the wearer of the wearable terminal device 10 to switch to automatic shooting mode. In step S2, the operation mode switching unit 102 switches the operation mode of the wearable terminal device 10 to automatic shooting mode. In automatic shooting mode, the wearable terminal device 10 repeatedly performs the processes of steps S3 to S5.

[0056] In step S2, the image generation unit 103 causes the camera 16 to perform an image capture process and generates a two-dimensional captured image. In step S3, the image generation unit 103 causes the distance measuring sensor 17 to perform a measurement process and generates a depth image. In step S4, the transmission unit 106 transmits the generated two-dimensional captured image and depth image, along with the distance information calculated by the distance measuring sensor 17, to the information processing device 20, along with the identification information of the wearable terminal device 10.

[0057] When the information processing device 20 receives the 2D captured image, depth image, distance information, and identification information of the wearable terminal device 10 transmitted by the wearable terminal device 10, in step S6, the pressure ulcer detection unit 201 of the information processing device 20 detects a pressure ulcer from the 2D captured image and depth image. In step S7, the depth calculation unit 203 calculates the depth of the pressure ulcer. In step S8, the size calculation unit 205 calculates the major and minor diameters of the pressure ulcer. In step S9, the superimposed image generation unit 207 generates a superimposed image. In step S10, the transmission unit 212 transmits the superimposed image, depth information, pressure ulcer size information, and identification information of the pressure ulcer to the wearable terminal device 10. Here, the transmission unit 212 can identify the destination wearable terminal device 10 using the identification information of the wearable terminal device 10 received along with the 2D captured image and depth image.

[0058] When the wearable terminal device 10 receives the superimposed image, depth information, and size information transmitted by the information processing device 20, in step S11, the display control unit 105 of the wearable terminal device 10 displays the received superimposed image, depth information, and size information on the display 15. Figure 11 is a diagram showing an example of an image displayed on the display 15 of the wearable terminal device 10. As shown in Figure 11, the display 15 displays the superimposed image 50, depth information, and size information.

[0059] Next, when the wearer of the wearable terminal device 10 instructs the wearable terminal device 10 to register information about pressure ulcers, in step S12 the instruction receiving unit 101 of the wearable terminal device 10 receives the instruction to register information about pressure ulcers. In step S13, the transmission unit 106 transmits the registration instruction, the pressure ulcer information ID, and the patient ID to the information processing device 20. The patient ID can be specified by the wearer of the wearable terminal device 10. In step S14, the operation mode switching unit 102 switches the operation mode of the wearable terminal device 10 to normal operation mode.

[0060] When the information processing device 20 receives the registration instruction, pressure ulcer information ID, and patient ID transmitted by the wearable terminal device 10, in step S14, the transmission unit 212 of the information processing device 20 transmits the superimposed image, depth information, and size information associated with the pressure ulcer information ID in the transmission history table, along with the patient ID, to the electronic medical record management device 30.

[0061] When the electronic medical record management device 30 receives the superimposed image, depth information, size information, and patient ID, in step S15, the registration unit 301 associates the superimposed image, depth information, and size information with the patient ID and saves them in the electronic medical record information table.

[0062] Figure 13 shows the main components of the pressure ulcer recording support system 1. The pressure ulcer recording support system 1 includes an image generation unit 103, a pressure ulcer detection unit 201, a depth calculation unit 203, and a registration unit 301. The image generation unit 103 generates a depth image showing the pressure ulcer using distance information of the patient's pressure ulcer calculated by a distance measuring sensor 17 provided in the wearable terminal device 10. The pressure ulcer detection unit 201 detects the pressure ulcer from the depth image. The depth calculation unit 203 calculates depth information indicating the depth of the detected pressure ulcer. The registration unit 301 registers the calculated depth information. By adopting this configuration, the depth of the pressure ulcer can be recorded.

[0063] Furthermore, in the embodiment described above, the display control unit 105 displays the calculated depth information on the display unit 15 of the wearable terminal device 10. This allows the wearer of the wearable terminal device 10 to check the depth information of the pressure ulcer.

[0064] Furthermore, in the embodiment described above, the instruction receiving unit 101 receives instructions from the wearer wearing the wearable terminal device 10. When the instruction receiving unit 101 receives an instruction to register information about pressure ulcers displayed on the display unit 15 of the wearable terminal device 10, the registration unit 301 registers the depth information as electronic medical record information. By adopting this configuration, the wearer of the wearable terminal device 10 can instruct the registration of pressure ulcer depth information at the timing when the desired pressure ulcer depth information is displayed on the display unit 15, and that depth information can be registered as electronic medical record information.

[0065] Furthermore, in the embodiment described above, the image generation unit 103 generates an image of the pressure ulcer using the imaging device 16 provided by the wearable terminal device 10. When the instruction reception unit 101 receives an instruction to register information about the pressure ulcer displayed on the display unit 15, the registration unit 301 registers the image of the pressure ulcer with an image object indicating scale superimposed as electronic medical record information. By adopting this configuration, it is possible to register an image of a pressure ulcer with an image object indicating scale superimposed as electronic medical record information.

[0066] Furthermore, in the embodiment described above, the voice acquisition unit 100 acquires the voice collected by the sound collection unit 18 of the wearable terminal device 10. The voice information analysis unit 208 analyzes the acquired voice information and outputs character information representing the words contained in the voice information. The patient information extraction unit 210 extracts patient information from the output character information. The patient information storage unit 302 stores the extracted patient information in the storage unit 14. By adopting this configuration, the wearer of the wearable terminal device 10 can register patient information that has been verbally explained.

[0067] In the embodiment described above, the wearable terminal device 10 automatically generates a two-dimensional image and depth image of the pressure ulcer after switching to automatic shooting mode. However, in other embodiments, the wearable terminal device 10 may generate a two-dimensional image and depth image of the pressure ulcer each time it receives an individual shooting instruction from the wearer.
