Description

[Technical field]

[0001] The present disclosure relates to ophthalmic systems. [Background technology]

[0002] There are known systems that allow an examiner to remotely operate an ophthalmic apparatus using a host device via the Internet or the like (hereinafter, may be abbreviated as "examiner remote operation") (see, for example, Patent Documents 1 and 2). In addition, when remote operation by an examiner is possible, there are known systems in which a microphone is provided in the host device and a speaker is provided in the ophthalmic apparatus, and the examiner's voice is notified to the subject through the speaker (see, for example, Patent Document 3). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-073686 [Patent Document 2] JP 2023-039506 A [Patent Document 3] JP 2018-166649 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, although the examiner can remotely operate the ophthalmic device, the examiner cannot switch between the examination mode and the sleep mode, and therefore the examiner must visit a remote location to switch the mode of the ophthalmic device. Here, the examination mode is a mode (activated state) in which the ophthalmic device can perform examination. In contrast, the sleep mode is a mode in which a member of the ophthalmic device that suspends part of the operation of the ophthalmic device and receives a signal to activate (restart) the suspended part of the ophthalmic device is activated. This member is, for example, a LAN chip (LAN is an abbreviation for Local Area Network). In other words, the sleep mode is a mode in which the ophthalmic device suspends operation and waits for a signal to activate, that is, a suspending state (standby state). In addition, the sleep mode is a mode (low power consumption state) in which the power consumption of the ophthalmic device can be reduced more than that of the examination mode because part of the operation of the ophthalmic device is suspended, and the ophthalmic device can be switched to the examination mode more quickly than when the power of the ophthalmic device is completely turned off.

[0005] The present disclosure has been made in response to the above-mentioned problems, and aims to provide an ophthalmic system that allows an examiner to remotely transition from sleep mode to examination mode when the examiner remotely operates an ophthalmic device using a host device. [Means for solving the problem]

[0006] The ophthalmic system of the present disclosure includes an ophthalmic device and a host device located remotely from the ophthalmic device. In the ophthalmic system, the ophthalmic device and the host device are capable of communicating with each other, and an examiner remotely operates the ophthalmic device using the host device. The ophthalmic device has a control unit that transitions the ophthalmic device to an examination mode in which examination can be performed when a wake signal is input when the ophthalmic device on the subject side is in a sleep mode in which it is inactive. Effect of the Invention

[0007] According to the ophthalmologic system of the present disclosure, when an examiner remotely operates an ophthalmologic apparatus using a host device, the examiner can remotely switch the ophthalmologic apparatus from the sleep mode to the examination mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An embodiment for carrying out the ophthalmologic system according to the present disclosure will be described as follows based on Example 1 shown in the drawings. In the drawings, among the mutually orthogonal XYZ directions (three axial directions), the Y direction is the up-down direction. The Z direction is the front-back direction (working distance direction) parallel to the front direction approaching the subject's eye (not shown) and the rear direction moving away from the subject. The X direction is the left-right direction perpendicular to both the up-down direction and the front-back direction. EXAMPLES

[0010] An ophthalmic system 1 applied to the first embodiment will be described with reference to FIG. 1. As shown in FIG. 1, the ophthalmic system 1 includes one ophthalmic apparatus 10 and one remote control apparatus 30 (host apparatus). The remote control apparatus 30 is located at a remote position from the ophthalmic apparatus 10. In other words, the ophthalmic apparatus 10 and the remote control apparatus 30 are located at separate positions. For example, the ophthalmic apparatus 10 and the remote control apparatus 30 are located in adjacent rooms. Alternatively, the remote control apparatus 30 is located at a hospital to which the examiner belongs, and the ophthalmic apparatus 10 is located at a remote position away from the hospital. Therefore, the examiner is located at the location where the remote control apparatus 30 is located, and the subject is located at the location where the ophthalmic apparatus 10 is located.

[0011] The remote control device 30 is connected to a communication network such as the Internet 101 via a router 100 (router device). The remote control device 30 is connected to the ophthalmic apparatus 10 via the Internet 101. This allows an examiner to remotely control the device.

[0012] The ophthalmic apparatus 10 is placed on an eye examination table 200 and is used to examine the subject's eye. The ophthalmic apparatus 10 is a multifunction machine capable of measuring the intraocular pressure value, eye refractive power, corneal curvature, etc. of the subject's eye. Therefore, the ophthalmic apparatus 10 measures various eye characteristics of the subject's eye, such as the intraocular pressure value, eye refractive power, and corneal curvature (corneal shape), by remote operation by an examiner. The ophthalmic apparatus 10 includes a base unit 11, a face support unit 12, a drive mechanism 13, a measurement head 14, a monitor unit 15, a subject speaker 16 (speaker), a subject microphone 17 (microphone), a camera 18, and an apparatus control unit 20 (control unit, see FIG. 2).

[0013] The base portion 11 supports members such as a face support portion 12 and a drive mechanism 13 that are placed on the upper side of the base portion 11 .

[0014] The face support section 12 supports the face of the subject. The face support section 12 is disposed in front of the drive mechanism 13. The face support section 12 is integrally provided with a chin rest section 12a, a forehead rest section 12b, and a pair of frames 12c. The chin rest section 12a supports the subject's chin. The forehead rest section 12b is in contact with the subject's forehead. The pair of frames 12c connect the chin rest section 12a and the forehead rest section 12b. The subject faces the ophthalmologic device 10 while sitting on a chair or the like (not shown) provided in front of the ophthalmologic device 10. Next, the subject undergoes the examination with his / her chin placed on the chin rest section 12a and his / her forehead in contact with the forehead rest section 12b.

[0015] The driving mechanism 13 corresponds to the relative movement mechanism of the ophthalmologic apparatus 10. The driving mechanism 13 is composed of an actuator (not shown), such as a motor. The driving mechanism 13 is driven based on control information (control signal) from the device control unit 20. Based on the control information, the driving mechanism 13 can move the chin rest part 12a up and down in the Y direction. Based on the control information, the driving mechanism 13 also moves the measurement head 14 in the XYZ directions relative to the base part 11. This allows the measurement head 14 to move in the XYZ directions relative to the subject's eye. In this way, the height of the chin rest part 12a can be adjusted, and the measurement head 14 can be aligned in the XYZ directions relative to the subject's eye.

[0016] A known optical system for observation and photography is provided inside the measurement head 14. The optical system allows various eye characteristics of the subject to be observed and photographed. Specifically, the measurement head 14 is provided with a variety of ophthalmic measurement devices including an autorefkeratometer 14A. The autorefkeratometer 14A measures the ocular refractive power and corneal curvature of the subject's eye using various optical systems. The specific configuration of the autorefkeratometer 14A is a known technique, and therefore will not be described here.

[0017] The monitor unit 15 is attached to the rear side of the measurement head 14. The monitor unit 15 is, for example, a touch panel monitor. The monitor unit 15 displays an observation image of the subject's eye, etc., based on control information from the device control unit 20. The monitor unit 15 displays measurement results of eye characteristics such as the intraocular pressure value, eye refractive power, and corneal curvature of the subject's eye. The monitor unit 15 displays an operation menu screen, etc. for performing various operations. The monitor unit 15 also accepts operation inputs for each operation menu screen. This allows an examiner near the subject or the subject himself to directly operate the ophthalmic device 10.

[0018] The subject speakers 16 are built into each of the pair of frames 12c. The subject speakers 16 are positioned near the left and right ears of the subject during eye examination.

[0019] The subject microphone 17 is built in the center of the chin rest portion 12a. The subject microphone 17 is located near the mouth of the subject during the eye examination.

[0020] The camera 18 is provided on the upper part of the monitor unit 15. The camera 18 is provided at a position where the subject is reflected when in the examination posture. Therefore, the camera 18 can photograph the subject when in the examination posture, and can also photograph the subject standing on the front side of the face support unit 12. In addition, the camera 18 is for peripheral photography, capable of photographing the periphery of the ophthalmic device 10, i.e., the front side of the position of the camera 18. The subject standing on the front side of the face support unit 12 is photographed in order to photograph the subject who has come to undergo the examination. In addition, the periphery of the ophthalmic device 10 is photographed in order to photograph the subject who is not reflected on the front side of the face support unit 12.

[0021] Here, the examination postures include a posture of the subject sitting on a chair or the like (not shown) provided in front of the ophthalmic apparatus 10, a posture of the subject resting his / her chin on the chin rest 12a and his / her forehead against the forehead rest 12b, and a posture of the subject standing in front of the face support unit 12. As will be described later, the image display information (captured image) of the camera 18 is displayed on the examiner monitor unit 32, so that the examiner can check the image display information. Therefore, the examiner can observe the condition of the subject before, during, and after the examination by the display on the examiner monitor unit 32. In addition, the examiner can use the display on the examiner monitor unit 32 to adjust the position of the ophthalmic apparatus 10 and the subject.

[0022] Next, the control system of the ophthalmologic system 1 will be described as follows with reference to FIG.

[0023] The ophthalmologic apparatus 10 includes an apparatus control unit 20, a communication interface 21, and a remote operation reception unit 22 in addition to the above configuration.

[0024] The remote control device 30 includes an operation unit 31, an examiner monitor unit 32, an examiner speaker 33 (speaker), an examiner microphone 34 (microphone), and a main body control unit 35.

[0025] The communication interface 21 and the main body control unit 35 are connected to each other via the Internet 101 and the router 100. The communication interface 21 and the main body control unit 35 input and output various information (control signals, etc.) between each other via the router 100 and the Internet 101. In the following explanation, the statement "via the router 100 and the Internet 101" may be omitted.

[0026] Since the ophthalmologic apparatus 10 is remotely operated by the examiner, the remote control device 30 will be described first.

[0027] The remote control device 30 is, for example, a personal computer, a tablet terminal, etc. The remote control device 30 is used when an examiner operates the ophthalmologic apparatus 10 remotely.

[0028] The operation unit 31 is, for example, a keyboard and a mouse. Operation information for an examiner to remotely operate the ophthalmologic apparatus 10 is input to the operation unit 31. The operation unit 31 outputs the input operation information to the main body control unit 35.

[0029] For example, a liquid crystal display is used as the examiner monitor unit 32. The examiner monitor unit 32 displays display information input from the main body control unit 35. The display information includes display information of the examination mode or sleep mode of the ophthalmic apparatus 10, image display information of the camera 18, and the same display information as the display screen of the monitor unit 15 of the ophthalmic apparatus 10, etc.

[0030] For example, a headset (headphones with a microphone) is used for the examiner speaker 33 and the examiner microphone 34. The examiner speaker 33 outputs the examinee's voice (examinee's voice information) input to the examinee microphone 17. The examiner microphone 34 outputs the examiner's voice (examiner's voice information) input to the main body control unit 35.

[0031] The main body control unit 35 includes an arithmetic circuit configured with various processors and memories (storage units). The various processors include a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), and a programmable logic device (e.g., simple programmable logic devices (SPLD), complex programmable logic devices (CPLD), and field programmable gate arrays (FPGA)). The various controls (functions) of the main body control unit 35 may be realized by one processor or by multiple processors of the same or different types.

[0032] The main body control unit 35 outputs operation information, examiner voice information, etc. to the communication interface 21. Display information, examinee voice information, etc. are input to the main body control unit 35 from the communication interface 21. The main body control unit 35 accepts the display information, examinee voice information, etc., and controls the operation of the remote control device 30 by reading and executing a control program stored in a memory (not shown). For example, the main body control unit 35 outputs display information to the examiner monitor unit 32, and outputs examinee voice information to the examiner speaker 33. The main body control unit 35 also outputs operation information, etc. to the device control unit 20 based on operation information, etc. input from the operation unit 31.

[0033] Next, the ophthalmic apparatus 10 will be described.

[0034] The communication interface 21 and the remote operation reception unit 22 constitute the LAN chip. The communication interface 21 receives operation information, examiner voice information, etc. from the main body control unit 35. The communication interface 21 outputs the operation information, examiner voice information, etc. to the remote operation reception unit 22. The communication interface 21 also receives display information, examinee voice information, etc. from the device control unit 20. The communication interface 21 outputs the display information, examinee voice information, etc. to the main body control unit 35.

[0035] The remote operation reception unit 22 receives operation information, examiner voice information, etc. from the communication interface 21. The remote operation reception unit 22 receives the operation information, examiner voice information, etc., and outputs the operation information, examiner voice information, etc. to the device control unit 20. The remote operation reception unit 22 receives a wake signal or a sleep signal as operation information, and outputs these signals to the device control unit 20.

[0036] The device control unit 20, like the above-mentioned main body control unit 35, includes an arithmetic circuit configured with various processors and memories (storage units), etc. The various controls (functions) of the device control unit 20 may be realized by one processor, or may be realized by multiple processors of the same or different types.

[0037] The device control unit 20 controls the operation of the ophthalmologic device 10 by reading and executing a control program stored in a memory (not shown) based on operation information, examiner voice information, etc. input from the remote operation receiving unit 22. The device control unit 20 also outputs subject voice information, etc. to the main body control unit 35 based on subject voice information, etc. input from the subject microphone 17. The device control unit 20 functions as a mode transition control, an examination guidance control, an examination execution control, a display control, an audio control, etc.

[0038] When the device control unit 20 receives a sleep signal from the remote operation reception unit 22, it controls to turn off all power supplies to the ophthalmic apparatus 10 except for the communication interface 21 and the remote operation reception unit 22. Then, the device control unit 20 suspends operation of the ophthalmic apparatus 10 except for a portion thereof, and transitions the ophthalmic apparatus 10 to a sleep mode. Furthermore, when the device control unit 20 receives a wake signal from the remote operation reception unit 22, it controls to turn on all power supplies to the ophthalmic apparatus 10, and transitions the ophthalmic apparatus 10 to an examination mode.

[0039] Next, the flow of processing of the ophthalmologic apparatus 10 will be described as follows using examples of the flowcharts in Fig. 3 to Fig. 5. In the flowcharts in Fig. 3 to Fig. 5, various information output from the main body control unit 35 is input to the device control unit 20 via the communication interface 21 and the remote operation reception unit 22. For this reason, in the description of the flowcharts, the description "via the communication interface 21" and "via the communication interface 21 and the remote operation reception unit 22" may be omitted. Conversely, various information output from the device control unit 20 is input to the main body control unit 35 via the communication interface 21. For this reason, the description "via the communication interface 21" may be omitted.

[0040] First, the process flow of the ophthalmic apparatus 10 will be described below using an example of a flowchart in FIG. 3. Since the ophthalmic apparatus 10 is in sleep mode until the examiner starts remote operation, the program starts the process flow in sleep mode. "Until the examiner starts remote operation" refers to, for example, until the hospital starts examining the patient. In sleep mode, the chin rest 12a, the drive mechanism 13, the measuring head 14, the monitor unit 15, the examinee speaker 16, the camera 18, and the device control unit 20 are inactive. Even in sleep mode, the communication interface 21 and the remote operation reception unit 22 are operating. The communication interface 21 and the remote operation reception unit 22 are members that receive a signal to start (restart) the ophthalmic apparatus 10.

[0041] In step S1, following the start of processing, the remote operation reception unit 22 determines whether or not a wake signal has been received. If YES, proceed to step S2, and if NO, repeat step S1. When the ophthalmic device 10 is in sleep mode, the ophthalmic device 10 waits for a wake signal from the main body control unit 35. When a wake signal is output from the main body control unit 35 in response to an operation input by the examiner on the operation unit 31, the remote operation reception unit 22 receives the wake signal. Then, the remote operation reception unit 22 determines that the wake signal has been received. Here, if it continues to be determined that the wake signal has not been received, step S1 is repeated.

[0042] In step S2, following receipt of the wake signal in step S1, the remote operation reception unit 22 and the device control unit 20 execute an examination mode transition process, and the process proceeds to step S3. In the examination mode transition process, first, since the remote operation reception unit 22 receives the wake signal in step S1, the remote operation reception unit 22 outputs the wake signal to the device control unit 20. As a result, the device control unit 20 starts (operates) in response to the input of the wake signal. Next, the device control unit 20 controls to start up the chin rest unit 12a, the drive mechanism 13, the measurement head 14, the monitor unit 15, the subject speaker 16, and the camera 18. In other words, the device control unit 20 controls to turn on all power supplies to the ophthalmic device 10.

[0043] Furthermore, even if a wake signal is input, the device control unit 20 does not perform control to activate the subject microphone 17. Next, a mode transition control is performed to transition the ophthalmic apparatus 10 from the sleep mode to the examination mode. Note that, after performing the mode transition control to transition the ophthalmic apparatus 10 from the sleep mode to the examination mode, the device control unit 20 may perform control to activate the ophthalmic apparatus 10 (the chin rest 12a, etc.) that is out of operation.

[0044] In step S3, following the examination mode transition process in step S2, the determination of evacuation detection in step S7, or the determination of non-reception of a sleep signal in step S11, the device control unit 20 determines whether or not the subject's figure has been detected. If YES, proceed to step S4, and if NO, proceed to step S11. The detection of the subject's figure, that is, the detection of the subject's presence, is determined from the image of the camera 18. First, the image display information of the camera 18 is output from the camera 18 to the main body control unit 35 through the device control unit 20. As a result, the main body control unit 35 displays the image display information on the examiner monitor unit 32. The main body control unit 35 displays the image display information on the examiner monitor unit 32 while the camera 18 is operating.

[0045] Next, the examiner checks the presence of the subject from the display of the examiner monitor unit 32. When the subject is present, this does not necessarily mean that the entire body of the subject is shown, but also includes the case where a part of the subject, such as the head, is shown. Regarding the result of the recognition of the presence of the subject, the examiner operates the operation unit 31 to output the presence detection information or the non-detection of presence information as operation information from the main body control unit 35 to the device control unit 20. The presence detection information is information that the examiner has recognized the presence of the subject and therefore detected the presence of the subject (presence detection). The non-detection of presence information is information that the examiner has not recognized the presence of the subject and therefore has not detected the presence of the subject (presence non-detection). When the presence detection information is input, the device control unit 20 judges the presence as detected in step S3. On the other hand, when the non-detection of presence information is input, the device control unit 20 judges the presence as non-detection in step S3.

[0046] In step S4, following the determination of presence detection in step S3, the device control unit 20 executes an inspection guidance process, and the process proceeds to step S5. The inspection guidance process will be described later with reference to the flowchart of FIG.

[0047] In step S5, following the test guidance process in step S4, the device control unit 20 executes a test execution process, and the process proceeds to step S6. The test execution process will be described later with reference to the flowchart of FIG.

[0048] In step S6, following the test execution process in step S5 or the determination of evacuation undetected in step S7, the device control unit 20 executes a test end notification process, and the process proceeds to step S7. The test end notification process is a process for notifying the subject that the test has ended. When the process proceeds to step S6, the device control unit 20 automatically inputs automatic voice information to the subject speaker 16, causing the subject speaker 16 to output automatic voice information. Alternatively, the device control unit 20 may input end notification display information to the monitor unit 15 to notify the end, causing the monitor unit 15 to display end notification display information. The automatic voice information and end notification display information are, for example, "Please remove your face from the frame. All tests have been completed. Thank you for your hard work." Here, if the process returns to step S6 following the determination of evacuation undetected in step S7, the subject will be prompted to evacuate again.

[0049] In step S7, following the examination end notification process in step S6, the device control unit 20 determines whether the subject has evacuated. If YES, the process returns to step S3, and if NO, the process returns to step S6. Whether the subject is not detected, that is, whether the subject has evacuated, is determined from the image of the camera 18. First, the image display information of the camera 18 is output from the camera 18 to the main body control unit 35 via the device control unit 20. As a result, the main body control unit 35 displays the image display information on the examiner monitor unit 32. The main body control unit 35 displays the image display information on the examiner monitor unit 32 while the camera 18 is operating.

[0050] Next, the examiner checks the subject's evacuation from the display of the examiner monitor unit 32. The case where the subject has evacuated does not include the case where a part of the subject, such as the head, is shown, but the case where the whole body of the subject is not shown. Regarding the result of the recognition of the subject's evacuation, evacuation detection information or evacuation non-detection information is output as operation information from the main body control unit 35 to the device control unit 20 by the operation input of the operation unit 31 by the examiner. The evacuation detection information is information that the examiner has not recognized the presence of the subject, has recognized the evacuation of the subject, and has detected the evacuation of the subject (evacuation detection). The evacuation non-detection information is information that the examiner has recognized the presence of the subject, has not recognized the evacuation of the subject, and has not detected the evacuation of the subject (evacuation non-detection). When the evacuation detection information is input, the device control unit 20 judges that evacuation has been detected in step S7. On the other hand, when the evacuation non-detection information is input, the device control unit 20 judges that evacuation has not been detected in step S7. Here, if the determination in step S7 that evacuation has not been detected continues, steps S6 and S7 are repeated.

[0051] In step S11, following the determination of non-detection of presence in step S3, the remote operation reception unit 22 determines whether or not a sleep signal has been received. If YES, proceed to step S12, and if NO, return to step S3. In step S11, when the ophthalmic apparatus 10 is in the examination mode, if a sleep signal is output from the main body control unit 35 in response to an operation input by the examiner on the operation unit 31, the remote operation reception unit 22 receives the sleep signal. Then, the remote operation reception unit 22 determines that the sleep signal has been received. Here, if the determination of non-detection of presence in step S3 and the determination of non-reception of the sleep signal in step S11 continue, steps S3 and S11 are repeated.

[0052] In step S12, following the reception of the sleep signal in step S11, the remote operation reception unit 22 and the device control unit 20 execute a sleep mode transition process and proceed to RETURN. In the sleep mode transition process, first, since the remote operation reception unit 22 received the sleep signal in step S11, the remote operation reception unit 22 outputs a sleep signal to the device control unit 20. As a result, the device control unit 20 performs control to suspend the operations of the chin rest unit 12a, the drive mechanism 13, the measuring head 14, the monitor unit 15, and the camera 18.

[0053] Furthermore, when the subject speaker 16 and the subject microphone 17 are operating, the device control unit 20 performs control to suspend the operation of the subject speaker 16 and the subject microphone 17. Next, the device control unit 20 performs mode transition control to transition the ophthalmic apparatus 10 from the examination mode to the sleep mode, and performs control to suspend the device control unit 20. In other words, the device control unit 20 performs control to turn off all power supplies to the ophthalmic apparatus 10 except for the communication interface 21 and the remote operation reception unit 22.

[0054] Next, the flow of the examination guidance process will be described as follows using an example of the flowchart in FIG.

[0055] Steps S41 to S45 are examination guidance processing for guiding the subject to the examination (ophthalmic device 10). The examination guidance control of the processing is performed by the device control unit 20. For example, when proceeding to step S4, guidance display information is automatically input from the device control unit 20 to the monitor unit 15, and the guidance display information is displayed on the monitor unit 15 (display control). The guidance display information is information for guiding the subject to the ophthalmic device 10.

[0056] In step S41, following the start of the examination guidance process, a message to have the subject take a seat is displayed on the monitor unit 15, and the process proceeds to step S42.

[0057] In step S42, following the display in step S41, a display explaining the setting position of the subject's face is displayed on the monitor unit 15, and the process proceeds to step S43.

[0058] In step S43, following the display in step S42, a display indicating the position of subject microphone 17 is displayed on monitor unit 15, and the process proceeds to step S44.

[0059] In step S44, following the display in step S43, a display of precautions to be taken during the examination by the ophthalmic apparatus 10 is displayed on the monitor unit 15, and the process proceeds to step S45.

[0060] In step S45, following the display in step S44, a display indicating that the examination should start in the ophthalmic apparatus 10 is displayed on the monitor unit 15, and the examination guidance process proceeds to the end.

[0061] Next, the flow of the test execution process will be described as follows using an example of the flowchart in FIG.

[0062] Steps S51 to S55 correspond to an examination execution process for performing an examination on the subject's eye by the ophthalmic apparatus 10. The examination execution control of the process is performed by the apparatus control unit 20 and remote operation by the examiner.

[0063] In step S51, following the start of the test execution process, the device control unit 20 executes a test explanation, and the process proceeds to step S52. The test explanation is executed by explaining that the test will be performed, and explaining that the subject can talk to the examiner by speaking into the subject microphone 17 if they have any questions. When the process proceeds to step S51, the device control unit 20 automatically inputs automatic voice information to the subject speaker 16, which then outputs automatic voice information. For example, "We will now perform an eye refractive power test. If you have any questions, you can talk to the microphone."

[0064] In step S52, following the execution of the explanation of the test in step S51, the interactive function is turned on, and the process proceeds to step S53. To turn on the interactive function, an on signal for turning on the subject microphone 17 is output to the device controller 20 via the main controller 35 in response to an operation input by the examiner on the operation unit 31. This causes the device controller 20 to perform on control (voice control) for switching on the subject microphone 17. Until the switch of the subject microphone 17 is turned off, subject voice information input to the subject microphone 17 is output to the main controller 35 via the device controller 20. This causes the main controller 35 to output subject voice information from the examiner speaker 33, so that the subject's questions, etc. can be conveyed to the examiner. The interactive function is a function that allows the subject and the examiner to converse with each other when this function is on.

[0065] In step S53, following the on control of the interactive function in step S52 or the determination in step S54 that the test is not yet completed, the ophthalmic test is actually performed, and the process proceeds to step S54. The ophthalmic test is performed when the examiner speaks into the examiner microphone 34 or operates and inputs the operation unit 31. The examiner's voice information and operation information input to the examiner microphone 34 are output to the device control unit 20 through the main body control unit 35. As a result, the device control unit 20 outputs the examiner's voice information from the examinee's speaker 16, allowing the examiner to give instructions to the examinee (voice control).

[0066] The device control unit 20 also controls the drive mechanism 13 based on the operation information to adjust the chin rest 12a in the Y direction and align the auto refractor 14A with the subject's eye in the approximate XYZ directions. In addition, the device control unit 20 controls the execution of examinations required for ophthalmic examinations based on the operation information. The measurement result information of the auto refractor 14A is displayed on the monitor unit 15 from the measurement head 14 via the device control unit 20. The measurement result information input to the device control unit 20 is also displayed on the examiner monitor unit 32 via the main body control unit 35.

[0067] In step S54, following the execution of the ophthalmic examination in step S53, the device control unit 20 judges whether the ophthalmic examination has actually ended. If YES, proceed to step S55, and if NO, return to step S53. The ophthalmic examination ends when all of the preset examination items have been completed. Therefore, the device control unit 20 judges whether all of the preset examination items have been completed based on the operation information and the measurement result information.

[0068] In step S55, following the determination of the end of the test in step S54, the interactive function is controlled to be turned off, and the test execution process proceeds to the end. To turn off the interactive function, an OFF signal that switches the subject microphone 17 from ON to OFF is output to the device controller 20 via the main body controller 35 in response to an operation input by the examiner on the operation unit 31. As a result, the device controller 20 performs OFF control (audio control) to switch off the subject microphone 17.

[0069] Next, the operation of the ophthalmologic system 1 of the first embodiment will be described as follows.

[0070] The ophthalmic apparatus 10 of the ophthalmic system 1 of the present disclosure includes a device controller 20. As shown in FIG. 3, when the ophthalmic apparatus 10 on the subject side is in sleep mode, a wake signal is input from the remote control device 30 on the examiner side to the device controller 20 (start, step S1). When the wake signal is input from the remote control device 30, the device controller 20 switches the ophthalmic apparatus 10 to the examination mode (steps S1 to S2). That is, the examiner does not need to visit a remote location to switch from the sleep mode to the examination mode. Therefore, when the examiner remotely operates the ophthalmic apparatus 10 using the remote control device 30, the examiner can remotely switch from the sleep mode to the examination mode.

[0071] The ophthalmic device 10 of the ophthalmic system 1 of the present disclosure has a camera 18. When a sleep signal is input from the remote control device 30 (YES in step S11), the device control unit 20 switches the ophthalmic device 10 from the examination mode to the sleep mode (step S12, return). However, the device control unit 20 sets a condition that the subject is not detected by the camera 18 (NO in step S3). That is, the examiner does not need to visit a remote location to switch from the examination mode to the sleep mode. Therefore, when the examiner remotely operates the ophthalmic device 10 using the remote control device 30, the examiner can remotely switch from the sleep mode to the examination mode. Also, when the subject is not detected, operating the ophthalmic device 10 would result in waste of power consumption, so the examiner remotely switches from the examination mode to the sleep mode. Therefore, the power consumption of the ophthalmic device 10 can be reduced more than in the examination mode.

[0072] As shown in Figs. 1 and 2, the ophthalmic device 10 of the ophthalmic system 1 of the present disclosure has a subject speaker 16 and a subject microphone 17. The remote control device 30 has an examiner speaker 33 and an examiner microphone 34. As shown in Figs. 3 and 5, the device control unit 20 turns on an interactive function that allows the subject and the examiner to talk to each other during the examination mode (steps S5 and S52). In detail, the device control unit 20 turns on an interactive function that allows the subject and the examiner to talk to each other during the examination mode and while the examination is being performed. Then, the examiner performs the ophthalmic examination using the ophthalmic device 10 (steps S53 and S54 in Fig. 5, NO). Therefore, the examiner and the subject can talk to each other during the examination period when the ophthalmic examination is actually being performed by the ophthalmic device 10.

[0073] When the ophthalmic examination is completed, the device control unit 20 of the ophthalmic system 1 of the present disclosure switches the interactive function from on to off (step S55 in FIG. 5). For example, if the interactive function continues to be on after the ophthalmic examination is completed, the sounds of the subject side input to the subject microphone 17 (the subject's voice and the surrounding sounds of the subject side, "surrounding sounds" being sounds around the ophthalmic apparatus 10, such as the sound of the subject walking and the sounds of peripheral devices) are output from the examiner speaker 33, which may cause the examiner to feel uncomfortable. In addition, when the ophthalmic examination is completed, the dialogue between the examiner and the subject becomes unnecessary, so there is no need to continue to keep the interactive function on. As a result, by switching the interactive function from on to off after the ophthalmic examination is completed, the sounds of the subject side are no longer output from the examiner speaker 33. This makes it possible to prevent the examiner from feeling uncomfortable.

[0074] 3, the device control unit 20 of the ophthalmic system 1 of the present disclosure transitions the ophthalmic device 10 to an examination mode, and when the device control unit 20 detects the subject, executes an examination guidance process to guide the subject to the examination (step S2, YES in step S3, step S4). That is, since the remote control device 30 is located at a remote location from the ophthalmic device 10, it is necessary to guide the subject to the ophthalmic device 10 in order to start the examination of the subject. Therefore, the examination guidance process is executed to guide the subject to the ophthalmic device 10.

[0075] When the ophthalmic examination is completed, the device control unit 20 of the ophthalmic system 1 of the present disclosure executes an examination end notification process to notify the subject that the examination has been completed (steps S5 and S6). That is, since the remote control device 30 is located at a remote location from the ophthalmic device 10, it is necessary to notify the subject that the examination has been completed. Therefore, by executing the examination end notification process, the subject can be notified that the examination has been completed, and the subject can recognize the completion of the examination.

[0076] The above describes the ophthalmic system 1 of the present disclosure based on Example 1. However, the specific configuration is not limited to Example 1, and design changes and additions are permitted as long as they do not deviate from the gist of the invention related to each claim in the scope of the claims.

[0077] In step S1 of the above-mentioned first embodiment, when a wake signal is output from the main body control unit 35 by the examiner's operation input of the operation unit 31, the process proceeds from step S1 to S2, and the ophthalmic device 10 transitions to the examination mode. However, the present invention is not limited to this, and the ophthalmic device 10 may transition to the examination mode based on the wake setting of a calendar in which a date and time are set in advance. As described above, if "until the examiner starts remote operation" is until the start of the examination at the hospital, the time of the examination start can be set in advance. Therefore, for example, the device control unit 20 may transition the ophthalmic device 10 to the examination mode based on the wake setting of a calendar in which the date and time of the examination start are set in advance.

[0078] The wake setting as described above may be stored in the memory of the device control unit 20, or may be stored in the memory of the remote control device 30. If it is stored in the memory of the remote control device 30, a wake signal is output from the main body control unit 35 to the device control unit 20 based on the wake setting. This eliminates the need for the examiner to operate the operation unit 31. This reduces the burden on the examiner.

[0079] In step S11 of the above-mentioned first embodiment, when a sleep signal is output by the examiner's operation input of the operation unit 31, the process proceeds from step S11 to step S12, and the ophthalmic device 10 transitions to the sleep mode. However, the present invention is not limited to this, and the device control unit 20 may transition the ophthalmic device 10 to the sleep mode based on the wake setting of a calendar in which a date and time are set in advance. As in the above, if "until the examiner starts remote operation" is until the start of the examination at the hospital, the time of the end of the examination can be set in advance. For this reason, the ophthalmic device 10 may transition to the sleep mode based on the sleep setting of a calendar in which the date and time of the end of the examination is set in advance, for example.

[0080] The sleep setting as described above may be stored in the memory of the device control unit 20, or may be stored in the memory of the remote operation device 30. If it is stored in the memory of the remote operation device 30, a sleep signal is output from the main body control unit 35 to the device control unit 20 based on the sleep setting. This eliminates the need for the examiner to operate the operation unit 31. This reduces the burden on the examiner.

[0081] In step S3 of the above-mentioned Example 1, an example has been shown in which the examiner confirms the presence of the subject, and the device control unit 20 judges whether or not the subject has been detected based on the presence detection information or non-presence detection information input from the main body control unit 35. Also, in step S7 of the above-mentioned Example 1, an example has been shown in which the examiner confirms the evacuation of the subject, and the device control unit 20 judges whether or not the subject has evacuated based on the evacuation detection information or evacuation non-detection information input from the main body control unit 35. However, the following configurations of Modifications 1 to 4 may also be used.

[0082] In the first modification, the remote control device 30 may have a subject detection function for detecting a subject, and the subject detection function may detect the presence of the subject. The subject detection function is a function that automatically outputs the presence detection information or the non-detection of presence information in step S3, and the evacuation detection information or the non-detection of evacuation information in step S7. For example, the subject detection function is an artificial intelligence processing unit, and the artificial intelligence processing unit is mounted on the remote control device 30. The artificial intelligence processing unit automatically detects the presence of the subject from the video display information. In other words, the artificial intelligence processing unit automatically performs presence detection, non-detection of presence, evacuation detection, and non-detection of evacuation from the video display information.

[0083] In detail, the artificial intelligence processing unit reads an AI model stored in the memory of the remote control device 30. The AI ​​model is a model created by learning characteristics such as skeletal information of a human subject in order to detect the subject. The artificial intelligence processing unit automatically uses the AI ​​model to recognize the presence of the subject from video display information composed of multiple still images (photographed images).

[0084] For this reason, in step S3, if the artificial intelligence processing unit recognizes that the presence of the subject is included in the image display information, the presence of the subject is detected. Conversely, if the artificial intelligence processing unit recognizes that the presence of the subject is not included in the image display information, the presence of the subject is not detected. Then, the presence detection information or the non-detection of the presence information is automatically output to the device control unit 20 through the main body control unit 35. Also, in step S7, if the artificial intelligence processing unit recognizes that the presence of the subject is not included in the image display information, the retreat of the subject is detected. Conversely, if the artificial intelligence processing unit recognizes that the presence of the subject is included in the image display information, the retreat of the subject is not detected. Then, the retreat detection information or the non-detection of the retreat information is automatically output to the device control unit 20 through the main body control unit 35. This eliminates the need for the examiner to confirm the presence of the subject. This reduces the burden on the examiner.

[0085] In the second modification, the subject detection function may be provided by the device control unit 20 instead of the remote control device 30, and the subject detection function detects the presence of the subject in the same manner as described above. The device control unit 20 then makes the decision in step S3 based on the presence detection information or the presence non-detection information, and makes the decision in step S7 based on the evacuation detection information or the evacuation non-detection information. This eliminates the need for the examiner to confirm the presence of the subject. This reduces the burden on the examiner. Note that, when the subject detection function is an artificial intelligence processing unit, it is assumed that an AI model is stored in the memory of the device control unit 20.

[0086] In the third modification, the subject detection function may be provided by the camera 18 instead of the remote control device 30, and the subject detection function detects the presence of the subject in the same manner as described above. Then, the camera 18 outputs presence detection information, non-presence detection information, evacuation detection information, or non-evacuation detection information to the device control unit 20. This eliminates the need for the examiner to confirm the presence of the subject. This reduces the burden on the examiner. In addition, when the subject detection function is an artificial intelligence processing unit, the camera 18 is provided with an arithmetic circuit composed of various processors and memories (storage units), etc., similar to the device control unit 20 of the first embodiment, and an AI model is stored in the memory provided in the camera 18.

[0087] In the fourth modification, the subject detection function may be a human sensor instead of the artificial intelligence processing unit. The human sensor is provided in the ophthalmic device 10 and connected to the device control unit 20. The human sensor automatically detects whether or not a subject is present. The detection range of the human sensor is, for example, the space in front of the ophthalmic device 10. Preferably, the detection range of the human sensor is the space in front of the face support unit 12. The human sensor outputs the detection result to the device control unit 20 as information (signal) on the presence or absence of the subject. Then, when information on the presence is input, the device control unit 20 judges that the presence is detected in step S3 and that the retreat is not detected in step S7. On the other hand, when information on the absence is input, the device control unit 20 judges that the presence is not detected in step S3 and that the retreat is not detected in step S7. This eliminates the need for the examiner to confirm the presence of the subject. This reduces the burden on the examiner.

[0088] In the above-mentioned modified example 3, in the sleep mode, the camera 18 and the artificial intelligence processing unit are assumed to be operating. In the sleep mode, the camera 18 may automatically output the presence detection information to the device control unit 20, thereby inputting a wake signal to the device control unit 20. In other words, the presence detection information is output from the camera 18 to the device control unit 20, and thus YES is determined in step S1 of FIG. 3. This eliminates the need for the examiner to operate the operation unit 31. This reduces the burden on the examiner. In addition, the presence detection information may be output from the camera 18 to the remote operation reception unit 22, and thus the remote operation reception unit 22 may determine that a wake signal has been received.

[0089] In addition, in the above-mentioned modification 4, the human presence sensor is assumed to be operating in the sleep mode. In the sleep mode, the human presence sensor may output information indicating a presence to the device control unit 20, thereby inputting a wake signal to the device control unit 20. In other words, the presence information is output from the human presence sensor to the device control unit 20, thereby determining YES in step S1 of FIG. 3. This eliminates the need for the examiner to operate the operation unit 31. This reduces the burden on the examiner. The presence detection information is output from the human presence sensor to the remote operation reception unit 22, which may cause the remote operation reception unit 22 to determine that a wake signal has been received.

[0090] In step S4 of the above-mentioned embodiment 1, an example has been shown in which guidance display information is automatically displayed on the monitor unit 15 when proceeding to step S4, but this is not limited to this. In step S4, when proceeding to step S4, the subject speaker 16 may automatically output guidance audio information by inputting guidance audio information from the device control unit 20 to the subject speaker 16 (audio control). The guidance audio information is information for guiding the subject to the ophthalmologic device 10.

[0091] In step S51 of the above-mentioned embodiment 1, an example has been shown in which the subject speaker 16 automatically outputs automatic voice information when the process proceeds to step S51, but this is not limiting. In step S51, when the process proceeds to step S51, automatic display information may be automatically input from the device control unit 20 to the monitor unit 15, so that the automatic display information is displayed on the monitor unit 15 (display control).

[0092] In step S52 of the above-mentioned first embodiment, an example is shown in which the interactive function is turned on following the execution of the test explanation in step S51, but this is not limited thereto. For example, the timing of turning on the interactive function may be following the determination of subject detection in step S3, or may be during the test guidance process in step S4. Alternatively, it may be during the test execution process in step S5 and before the execution of the test explanation in step S51. This allows the subject to convey a request to the examiner before step S52. For example, the request may be, "I want to go to the bathroom, so please wait a bit."

[0093] In step S54 of the above-mentioned first embodiment, an example in which the device control unit 20 judges whether the ophthalmic examination has actually ended or not has been shown, but the present invention is not limited to this. For example, after the examiner asks the subject, "Are you sure you want to end the examination?", if the subject answers YES, the process proceeds to step S55, and if NO, the process returns to step S53. As described in steps S52 and S53, the examiner and the subject can communicate with each other. If YES, the examiner operates the operation unit 31 to input an examination end command to the device control unit 20 through the main body control unit 35. In step S55, following the input of the examination end command, the interactive function is turned off, and the process proceeds to the end of the examination execution process. The examination end command may be a mode in which the interactive function is turned off.

[0094] In step S6 of the above-mentioned first embodiment, an example in which the device control unit 20 automatically performs the test end notification process has been shown, but the present invention is not limited to this. For example, the examiner may notify the subject that the test has ended through the examiner microphone 34, or the examiner may operate the operation unit 31 to output end notification display information as operation information from the main body control unit 35 to the device control unit 20, thereby executing the process of step S6.

[0095] In the above-mentioned first embodiment, the camera 18 is provided on the upper part of the monitor unit 15, but the present invention is not limited thereto. For example, the camera 18 may be a measurement camera (optical system for photographing) provided in the measurement head 14. In the case of a measurement camera, since it is for measurement, it is provided at a position where the subject is reflected at least in the examination posture. In this case, the examiner can confirm the presence of the subject in step S3 and the evacuation of the subject in step S7. In addition, in this case, the examiner can observe the condition of the subject before, during, and after the examination by the display of the examiner monitor unit 32. In addition, the examiner can use the display of the examiner monitor unit 32 to adjust the position between the ophthalmic apparatus 10 and the subject.

[0096] In the above-mentioned first embodiment, an example was shown in which the measurement head 14 was provided with the autorefractometer 14A, but a non-contact tonometer or the like may also be provided. The non-contact tonometer measures the intraocular pressure value of the subject's eye in a non-contact manner.

[0097] The ophthalmic system 1 of the above-mentioned embodiment 1 includes one ophthalmic device 10 and one remote control device 30 as shown in FIG. 1, but an ophthalmic system 1A of FIG. 6 may be used as a modified example 5. For example, the modified example 5 includes three ophthalmic devices 10A, 10B, and 10C as shown in FIG. 6. A communication network such as a router 100A (router device) and the Internet 101 is connected between the three ophthalmic devices 10A, 10B, and 10C and the remote control device 30A. The remote control device 30A outputs a wake signal or a sleep signal to each of the three ophthalmic devices 10A, 10B, and 10C via the router 100A and the Internet 101.

[0098] The remote control device 30A has the configuration of the remote control device 30 of the first embodiment. The remote control device 30A has a configuration capable of switching the connection of the router 100A to be connected to each of the three ophthalmic devices 10A, 10B, and 10C. Each of the three ophthalmic devices 10A, 10B, and 10C has the same configuration as that of the first embodiment. Each of the three ophthalmic devices 10A, 10B, and 10C can be remotely controlled by an examiner by switching the router 100A in the remote control device 30A to be connected to the remote control device 30A.

[0099] The configuration of the fifth modification eliminates the need for the examiner to visit a remote location to switch between the sleep mode and the examination mode. Therefore, when the examiner remotely operates the three ophthalmic devices 10A, 10B, and 10C using the remote operation device 30A, the examiner can remotely switch between the examination mode and the sleep mode. Although the fifth modification uses three ophthalmic devices 10A, 10B, and 10C, two or four or more ophthalmic devices, i.e., a plurality of ophthalmic devices, can be connected to one remote operation device 30A and the examiner can remotely switch between the modes by remote operation.

[0100] The ophthalmic system 1A of the fifth modification includes three ophthalmic devices 10A, 10B, and 10C and one remote control device 30A, but is not limited to this. It may be configured as in the sixth modification below. The ophthalmic system of the sixth modification includes one ophthalmic device and multiple remote control devices. A router (router device) and a communication network such as the Internet are connected between the one ophthalmic device and the multiple remote control devices. This allows the ophthalmic device and each remote control device to communicate with each other. Only one of the multiple remote control devices may be able to output a wake signal or a sleep signal to the ophthalmic device via the router and the Internet. In addition, the multiple remote control devices may be able to communicate with each other, so that examiners in charge of each remote control device can talk to each other.

[0101] The ophthalmic system of the sixth modification may include a plurality of ophthalmic devices and a plurality of remote control devices. A router (router device) and a communication network such as the Internet are connected between the plurality of ophthalmic devices and the plurality of remote control devices. This allows each ophthalmic device and each remote control device to communicate with each other. Only one of the plurality of remote control devices may be capable of outputting a wake signal or a sleep signal to a predetermined ophthalmic device selected by an examiner among the plurality of ophthalmic devices via the router and the Internet. Furthermore, a case in which one remote control device is in the middle of outputting various signals to a predetermined ophthalmic device will be described. In this case, another of the remaining remote control devices may be capable of outputting a wake signal or a sleep signal to another ophthalmic device selected by an examiner among the remaining ophthalmic devices via the router and the Internet. In addition, communication may be possible between the plurality of remote control devices, so that examiners in charge of each remote control device can talk to each other.
