Description

[Technical field]

[0001] The present invention relates to an auscultation evaluation system and an auscultation training evaluation method used for training in identifying auscultatory sounds, which is an important element of medical examination items, and in particular to an auscultation evaluation system and an auscultation training evaluation method useful for training by indirect auscultation using a stethoscope. [Background technology]

[0002] Traditionally, in clinical settings, the importance of physical assessment (physical examination techniques) has been advocated, which involves actually touching the patient's body through interviews, percussion, auscultation, visual inspection, or palpation to grasp symptoms, detect abnormalities early, and evaluate the physical health of the patient. Evaluation through physical assessment requires the solid acquisition of basic knowledge, techniques, and skills. In order to acquire such knowledge, techniques, and skills, it is ideal to actually come into contact with many patients under the guidance of an appropriate instructor.

[0003] Considering the reality that it is difficult to acquire knowledge, techniques and skills by actually interacting with many patients, doctors, pharmacists, nurses, medical students, pharmacy students and nursing students generally acquire knowledge from books and lectures, and acquire skills through exercises using simulators that mimic the human body under the supervision of an instructor.

[0004] In particular, with regard to auscultation, which is one of the important elements of a medical examination, it is necessary to acquire the techniques and skills reliably and appropriately by actually using a stethoscope to listen to various auscultatory sounds and having the results evaluated.

[0005] Recently, the importance of physical assessment and its implementation have been attracting more and more attention. However, the reality is that the training is not easy to implement regardless of place and time.

[0006] In addition, it is extremely important to acquire auscultation skills in medical education courses, because there are cases where the trainee must place the stethoscope on the correct body part of the patient and listen to the sounds heard through the stethoscope to narrow down the appropriate next examination.

[0007] Furthermore, for the auscultation portion of the medical interview diagnostic practical exam, for example, in order to evaluate more than 100 medical students in one day, it is necessary to prepare 10 mock examination rooms and place evaluators and mock patients in each room. This places a heavy burden on the examiners. Although remote evaluation using a simulator that mimics the human body and surveillance cameras has also been considered, there are cases where blind spots occur due to fixed-point surveillance, making it difficult to make an appropriate evaluation of the auscultation area.

[0008] The following Patent Document 1 discloses an auscultation training device that allows trainees to learn auscultation techniques for various cases. This device is characterized by the fact that it allows training in conditions close to actual auscultation movements by using a simulated stethoscope on the surface of a human body model, and that it is possible to change the body sounds reproduced in response to the auscultation movements in various ways and transmit them directly to the trainee's hearing.

[0009] The following Patent Document 2 discloses a simple and inexpensive auscultation training system that does not use a device for measuring the respiratory motion of a simulated patient. This system is composed of a simulated stethoscope consisting of a sound collection unit with a position display means, a tube and an ear tube, a position detection means for detecting the position of the sound collection unit, a body sound database, a body sound reproducing means, and a timing display means for displaying the repetition timing of the reproduced respiratory sound. The database holds information on the body sounds recorded in advance from a real patient in association with the position of the chest, and the body sound reproducing means includes an audio player, and retrieves predetermined body sound information from the database according to the position of the sound collection unit detected by the position detection means, and reproduces the body sound from the audio player. The trainee listens to the information through the ear tube, and the simulated patient watches the timing display means and adjusts his or her respiratory motion to the reproduced respiratory sound.

[0010] The following Patent Document 3 discloses an auscultation system used in auscultation training to acquire auscultation skills at the lowest possible cost. This system includes a camera that is positioned facing the person to be auscultated, and a processing unit that estimates the skeletal frame of the person from image data related to the person's image created by the camera, estimates the position where the stethoscope should be placed, separately recognizes or tracks the position of the stethoscope, compares the position where the stethoscope should be placed with the position of the stethoscope, and judges whether the stethoscope is placed on the person.

[0011] The following Patent Document 4 discloses an auscultation training system that reproduces breathing sounds that match the breathing timing of a simulated patient. This system includes a breathing sound reproduction unit that reproduces breathing sounds and a breathing detection sensor that detects the breathing waveform of a simulated patient, and determines the breathing phase based on the breathing waveform of the simulated patient detected by the breathing detection sensor, calculates the length of the immediately preceding expiration or inspiration based on the determined breathing phase, and controls the breathing sounds reproduced by the breathing sound reproduction unit based on the calculated length of expiration or inspiration.

[0012] The following Patent Document 5 discloses a mannequin device for training in auscultation of cardiac diseases, which is used for training in diagnostic techniques using auscultation of cardiac diseases in medical education courses, etc. This device is a mannequin with only the upper body made of a layer of urethane foam about 20 mm thick, with a speaker on the back of the urethane foam layer, and is configured to reproduce the sound of the heartbeat from the speaker in response to an electrical signal sent from outside the mannequin.

[0027] An embodiment of the present invention will now be described with reference to the drawings.

[0028] The auscultation evaluation system 10 of this embodiment is used for auscultation training evaluation for learning medical techniques and medical knowledge such as auscultation, and an auscultation evaluation management server (hereinafter referred to as "server") 100, a user terminal 200, and an evaluator terminal 300 are connected via a network 400. Auscultation training information including human body image information and various sound information (content information) storing various body sounds generated within the human body (e.g., lung sounds, heart sounds, bowel sounds, etc.) is sent from the server 100 to the user terminal 200. Based on the auscultation training information, the user terminal 200 displays and outputs the human body image information, and outputs as audio the sound information associated with each body part. In addition, information input on the user terminal 200 side, such as response information such as how long the sound information of which part of the human body image information displayed and output on the user terminal 200 was auscultated for, which part of the human body image information the sound information output as audio was identified as being sound information of, whether an auscultation operation corresponding to the case name presented in the task was performed, or how the condition of a specified part (e.g., health condition, case name, etc.) was identified, is sent to the server 100. The server 100 stores the response information sent from the user terminal 200, and evaluates its appropriateness and stores it. The evaluator terminal 300 has a function of checking and evaluating information (including response information) sent from the user terminal 200 via the server 100 .

[0029] The server 100 includes a central control processor 110, an input unit 120, an output unit 130, and a memory 140, which are connected to each other via a signal line 150. The server 100 has a function of sending auscultation training information and the like to a user terminal 200 via a network 400, receiving response information and the like to the auscultation training information sent from the user terminal 200, and evaluating, managing, and storing the information. The server 100 also has a function of receiving requirement information from an evaluator terminal 300 sent via the network 400, and sending information corresponding to the requirement information, including information on the evaluation result of the auscultation training by the user terminal 200, to the evaluator terminal 300.

[0030] The central control processing unit 110 has a function of managing the control processing of the server 100 and the entire system by referring to predetermined program information stored in the memory 140. The central control processing unit 110 also has a function of receiving information sent from the user terminal 200 or the evaluator terminal 300 via the input unit 120, and sending predetermined information corresponding to the received information to the user terminal 200 or the evaluator terminal 300 via the output unit 130.

[0031] The central control processing unit 110 also has a measurement function for measuring, as dwell time information, a part where a stethoscope cursor 222a described later is located, i.e., a part designated by the stethoscope cursor 222a as a part (particular part) for outputting sound information by voice (hereinafter, the part is referred to as a "designated particular part") in the human body image information displayed and output on the image display unit 232 of the user terminal 200, and storing the measured time information in the memory 140. Furthermore, the central control processing unit 110 has a color tone change function for referring to the dwell time information and, in accordance with a change in the dwell time information, changing the color tone of the designated particular part by referring to color tone information previously stored in the memory 140. The color tone change function may change the color tone of the designated particular part and may also display or hide text on the image display unit 232 under a predetermined condition. In addition, in the human body image information, the color tone may be changed for all specified specific parts, but the color tone may also be changed only based on the dwell time information of the stethoscope cursor 222a at any specific part, i.e., only at that specific part.

[0032] The input unit 120, under the management of the central control processor 110, has a function of receiving information sent from the outside and storing it in the memory 140. For example, it is functionally configured to receive response information, etc. sent from the user terminal 200 and store it in the memory 140. It is also functionally configured to receive additional information related to the response information, etc. of the user terminal 200 sent from the evaluator terminal 300 and store it in the memory 140.

[0033] The output unit 130 has an output function of outputting various information and sending it to the outside under the management of the central control processing unit 110. For example, it is functionally configured to send auscultation training information (including not only content information but also learning or test menus related to auscultation training, and information related to usage history and learning outcomes / test results) to the user terminal 200 or the evaluator terminal 300 via the network 400.

[0034] The memory 140 is a readable / writable storage device, and includes the following storage areas:

[0035] A program information storage area 140a that stores program information referenced by the central control processing unit 110 for various control processes and management. A human body image information storage area 140b for storing human body image information from the chest side and the back side related to auscultation training evaluation and various content information related to auscultation training evaluation A voice information storage area 140c for storing specific sound information (e.g., heart sound information and lung sound information) generated at each part associated with each part of the human body image information related to the auscultation training evaluation A dwell time information storage area 140d for storing dwell time information of the stethoscope cursor 222a at a specified specific part A color tone information storage area 140e for storing information regarding the change in color tone of the designated specific part in accordance with the change in the dwell time information of the stethoscope cursor 222a (including display or non-display of text information) A correspondence information storage area 140f for storing information on correspondence between sound information and text information specific to each case associated with each part of the human body image information, and information on correspondence between the dwell time information of the stethoscope cursor 222a and color tone change on the designated specific part. An evaluation information storage area 140g for storing evaluation information regarding the evaluation results of the auscultation training by the user terminal 200 Other information storage area 140h for storing other information 140i work area for carrying out various tasks A user information storage area 140j for storing the access history of the user terminal 200 to the server 100, history information and supplementary information regarding the implementation status of auscultation training, and response information to auscultation training, etc. An evaluator information storage area 140k for storing additional information on the access status (including requirements information) of the evaluator terminal 300 and the evaluation information of the user terminal 200 by the evaluator terminal 300

[0036] The server 100 stores the position of the stethoscope cursor 222a of the human body image information displayed and output on the user terminal 200 side as coordinate data in the memory 140. The server 100 is functionally configured to display the designated specific part in a darker color as the dwell time of the stethoscope cursor 222a on the designated specific part designated by the stethoscope cursor 222a, i.e., as the dwell time information changes. The server 100 is functionally configured to store in the memory 140 information such as auscultation part information in the auscultation training, response information including dwell time information, and access history in the auscultation training for each user terminal 200, and to make the information accessible from the evaluator terminal 300 at will.

[0037] Furthermore, the server 100 can be functionally configured to add coordinate data to the human body image information and simultaneously generate all sound information, including heart and lung sounds, so as to prevent discrepancies in heart and lung sounds during auscultation training. Moreover, if the generated sound is functionally configured to attenuate as it moves away from the coordinate center and to play back overlapping sounds where the coordinate planes overlap, the generated sound can be changed continuously and realistically.

[0038] The server 100 evaluates the response information to the auscultation training by the user terminal 200, for example, by comparing the position information and dwell time information of the stethoscope cursor 222a of the user terminal 200 for each part or each case with a table of appropriate position information and dwell time information for each part or each case that is stored and prepared in advance in the memory 140. This evaluation can be performed, for example, on a five-point scale. The server 100 may also be a cloud server.

[0039] The user terminal 200 includes a control processing unit 210 , an input unit 220 , an output unit 230 , and a memory 240 , which are connected to each other via a signal line 250 .

[0040] The control processing unit 210 has a function of referring to predetermined program information stored in the memory 240 and managing the control processing of the entire user terminal 200. The control processing unit 210 also has a function of sending information in the user terminal 200 to the outside via the output unit 230, and a function of storing input information from the input unit 220 in the memory 240 and sending it to the outside. The control processing unit 210 also has a function of receiving information sent from the outside via the input unit 220 as necessary, storing it in the memory 240, and outputting it to the output unit 230.

[0041] The input unit 220 has a function of storing input information in the memory 240 under the management of the control processing unit 210. The input unit 220 also has a function of receiving auscultation training information and the like transmitted via the network 400 and storing it in the memory 240.

[0042] Furthermore, the input unit 220 is provided with a specific part designation unit 222 having a stethoscope cursor 222a that has a specific part designation function for designating a specific part of human body image information associated with sound information specific to each part and each case, which is sent from the server 100 and displayed and output by the output unit 230. Here, the specific part designation unit 222 has a display switching function between human body image information from the chest side and human body image information from the back side.

[0043] The output unit 230 has an output function of displaying or outputting the information stored in the memory 240 under the management of the control processing unit 210. The output unit 230 also has a function of outputting the information stored in the memory 240 to the outside via the network 400.

[0044] Furthermore, the output unit 230 has an image display unit 232 that displays the human body image information sent from the server 100 as an image, and an audio output unit 234 that outputs audio information associated with a designated specific part of the human body image information. The audio output unit 234 may simultaneously output audio information associated with the designated specific part and a part in the vicinity of the designated specific part, or may simultaneously output audio information associated with a plurality of parts.

[0045] The memory 240 is a readable / writable storage device, and includes a program information storage area for storing program information referenced by the control processing unit 210 for various control processing and management, various information storage areas for storing various information transmitted via the network 400, and a work area for performing various tasks.

[0046] Thus, the user terminal 200 is functionally configured to, when the stethoscope cursor 222a is positioned (designated) at a specific part of the human body image information displayed and output by the output unit 230, output sound information of the part as auscultatory sound, via the output unit 230. The user terminal 200 is also functionally configured to display or hide, for example, the case name on the image display unit 232 under the management of the server 100 or the evaluator terminal 300. Moreover, it is preferable that the user terminal 200 is functionally configured to transmit response information, in particular, the position and dwell time information of the stethoscope cursor 222a, to the server 100 in real time.

[0047] The evaluator terminal 300 includes a control processing unit 310 , an input unit 320 , an output unit 330 , a memory 340 , and an auscultation evaluation management unit 350 , all of which are connected via a signal line 360 ​​.

[0048] The control processing unit 310 has a function of referring to predetermined program information stored in the memory 340 and managing the control processing of the entire evaluator terminal 300. The control processing unit 310 also has a function of sending information in the evaluator terminal 300 to the outside via the output unit 330, and a function of storing input information from the input unit 320 in the memory 340 and sending it to the outside. The control processing unit 310 also has a function of receiving information sent from the outside via the input unit 320 as necessary, storing it in the memory 340, and outputting it to the output unit 330.

[0049] The input unit 320 has a function of storing input information in the memory 340 under the management of the control processing unit 310. The input unit 320 also has a function of receiving information transmitted via the network 400 and storing it in the memory 340.

[0050] The output unit 330 has an output function of displaying and outputting information stored in the memory 340 and outputting audio under the management of the control processing unit 310. The output unit 330 also has a function of outputting the information stored in the memory 340 and the information from the auscultation evaluation management unit 350 to the outside via the network 400.

[0051] The memory 340 is a readable / writable storage device, and includes a program information storage area for storing program information referenced by the control processing unit 310 for various control processing and management, an auscultation evaluation information storage area for storing various auscultation evaluation information and other additional information, and a work area for performing various tasks.

[0052] The auscultation evaluation management unit 350, under the management of the control processing unit 310, has the function of managing and monitoring information such as auscultation training information stored in the server 100, response information sent from the user terminal 200, and the status of the evaluation.

[0053] That is, the auscultation evaluation management unit 350 has the following functions. Real-time monitoring of image information displayed and output on the user terminal 200 side and sound information output as audio - Connection status and identification of multiple user terminals 200 (including user information of the user terminals 200) and addition of additional information such as evaluation information regarding response information from each user terminal 200 · Settings such as collective or individual selection and modification of information sent from the server 100 to the user terminal 200 (e.g., setting of cases, etc.) Specifying the user terminal 200 that accesses the server 100 Viewing the history information and additional information of the user terminal 200 stored in the server 100

[0054] The operation of the above configuration will be described below.

[0055] First, a method for evaluating auscultation training using the auscultation evaluation system 10 will be described.

[0056] The server 100, the user terminal 200, and the evaluator terminal 300 are connected via a network 400, and when the user terminal 200 requests, for example, auscultation training information (e.g., content information) from the server 100, the server 100 sends the content information to the user terminal 200. The user terminal 200 then stores the sent content information in the memory 240, and displays and outputs the human body image information as a human body image (see HB in FIG. 6) via the image output unit 232 (see step S100 in FIG. 5). The data format and file format of the human body image information may be any format as long as it can be displayed on the image output unit 232 as a human body image.

[0057] To start auscultation training, the stethoscope cursor 222a is positioned at any part of the human body image HB displayed and output on the user terminal 200 (i.e., a specific part is specified with the stethoscope cursor 222a). Then, sound information of the specified specific part is output as auscultation sound via the audio output unit 234 (step S200). For example, when the stethoscope cursor 222a is positioned at the right chest part (HBR), lung sounds are output; when it is positioned at the heart part (HBH), heart sounds and lung sounds are output; when it is positioned at the right abdominal part (HBAR), abdominal sounds associated with that part are output; and when it is positioned at the left abdominal part (HBAL), abdominal sounds associated with that part are output.

[0058] Here, if the stethoscope cursor 222a is positioned, for example, halfway between the heart area (HBH) and the left abdominal area (HBAL), and sound information corresponding to both areas is generated simultaneously, sounds according to the distance from the central area of ​​each sound source are output in overlapping audio form.

[0059] Furthermore, as described above, when the stethoscope cursor 222a is positioned at any part of the human body image HB displayed on the user terminal 200 (i.e., a specific part is specified with the stethoscope cursor 222a), the dwell time of the stethoscope cursor 222a at the specific specified part is measured as dwell time information (step S300).

[0060] As the dwell time information changes, the color tone of the designated specific part in the human body image HB displayed and output on the user terminal 200, i.e., the part where the stethoscope cursor 222a is located, also changes (step S400). The longer the dwell time, the darker the color tone of the part becomes with the passage of time.

[0061] The server 100 evaluates the response information from the user terminal 200, ie, for example, the position information and dwell time information of the stethoscope cursor 222a, or the case name or the name of the next required examination (step S500).

[0062] For example, the response information to the auscultatory sounds output for each case is evaluated on a five-point scale according to the degree of deviation from a predetermined numerical value by comparing the position information and dwell time information of the stethoscope cursor 222a with a table of appropriate position information and dwell time information for each case stored in the memory 140. Information such as the evaluation results is stored in a specified area of ​​the memory 140 together with history information for each user terminal 200.

[0063] Furthermore, for example, with regard to response information to auscultatory sounds that are output as voice without disclosing the case name, when the case name based on the auscultatory sounds that are output as voice and the name of the next required examination are sent from the user terminal 200, the server 100 evaluates whether or not they are appropriate by referring to the memory 140. Information such as the evaluation results is stored in a specified area of ​​the memory 140 together with history information and the like for each user terminal 200.

[0064] The evaluation results are functionally configured to be sent to the user terminal 200 by default, but it is possible to change the settings before starting auscultation training so that they are not sent.

[0065] Next, a description will be given of characteristic functions on the user terminal 200 side in the auscultation training evaluation.

[0066] When the stethoscope cursor 222a is positioned at any part of the human body image HB displayed on the user terminal 200, the case name is displayed, including normal cases. When the part is enlarged, the case name is automatically hidden.

[0067] Furthermore, when starting an auscultation training evaluation, the user terminal 200 is functionally configured to display appropriate auscultation sites on the screen by using an auscultation site icon (not shown) for beginners provided on the user terminal 200 side.

[0068] Furthermore, after the user terminal 200 receives the auscultation training information (content information) sent from the server 100, the enlarged display function is available even when the terminal is disconnected from the network 400 (so-called offline state). However, instead of using this configuration, the content information sent from server 100 may be displayed on image output unit 232 in a so-called streaming format without being stored in memory 240, and response information, etc. may be stored in memory 240 from input unit 220 and output by output unit 230 to the outside (server 100) via network 400, or may be output to the outside (server 100) without being stored in memory 240.

[0069] Next, an example of a characteristic function on the evaluator terminal 300 side in the auscultation training evaluation will be described.

[0070] When starting an auscultation training evaluation by the user terminal 200, the evaluator terminal 300 can display the connection status of the user terminal 200 on the output unit 330 in real time, thereby enabling the user terminal 200 to be checked.

[0071] Furthermore, the evaluator terminal 300 is capable of identifying and designating a desired user terminal 200 from among a plurality of user terminals 200 and causing the output unit 330 to display information relating to that user terminal 200.

[0072] Furthermore, the evaluator terminal 300 can set and manage cases in the content information related to the auscultation training sent to the user terminal 200 via the auscultation evaluation management unit 350. Moreover, case setting and management can be performed for each user terminal 200. Also, additional information can be added to the evaluation related to the response information of the user terminal 200.

[0073] According to the above embodiment, auscultation training and its evaluation can be easily performed anywhere and at any time with a simple system configuration without requiring a large-scale system configuration.

[0074] Furthermore, according to the above embodiment, in the user terminal 200 and the evaluator terminal 300, an auscultation evaluation system that is easy to use, practical, and highly accurate can be realized at low cost, which is economical and useful.

[0075] Furthermore, according to the above embodiment, unlike the conventional medical interview practical examination, it is not necessary to provide many evaluators, mock patients, and mock examination rooms, which greatly reduces the burden on the examination organizer. Moreover, there are no blind spots, and appropriate training and evaluation can be realized.

[0076] The present invention is not limited to the above-described embodiment, and may be functionally configured to centrally manage the auscultation training and evaluation of the user terminal 200 at the evaluator terminal 300, for example. Of course, various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
