[0040] It should be noted that, in the present invention, when the handheld flash stimulator 114 and the trolley 101 are connected to each other, the two are fixed to each other and can move synchronously; when the handheld flash stimulator 114 and the trolley 101 are detached from each other, the two may not be fixed to each other, and the two are arranged at an interval. At this time, the user (such as a doctor) can grab the handheld flash stimulator 114 and move the handheld flash stimulator 114 relative to the trolley 101, thereby moving the handheld flash stimulator 114 to the position required by the user.

[0041] Similarly, when the handheld graphic stimulator 110 and the trolley 101 are connected to each other, the two are fixed to each other and can move synchronously; when the handheld graphic stimulator 110 and the trolley 101 are detached from each other, the two may not be fixed to each other, and the two are arranged at a distance. At this time, the user can grab the handheld graphic stimulator 110 and move the handheld graphic stimulator 110 relative to the trolley 101, thereby moving the handheld graphic stimulator 110 to the position required by the user.

[0042] For ordinary adult patients, the patient can sit in front of the desktop graphic stimulator 102 or the desktop flash stimulator 104 to receive the corresponding visual stimulation. Some patients may not be able to sit in front of the desktop graphic stimulator 102 or the desktop flash stimulator 104 due to other physical diseases. In addition, some patients may not be suitable for testing with the desktop graphic stimulator 102 and the desktop flash stimulator 104 due to short stature (for example, the patient is a child) or other reasons.

[0043] For patients who are not suitable for testing by the desktop graphic stimulator 102 and the desktop flash stimulator 104, the doctor can use the handheld flash stimulator 114 and the handheld graphic stimulator 110 to stimulate the patient's visual system. After the handheld flash stimulator 114 and the handheld graphic stimulator 110 are removed (removed from the trolley 101), the handheld flash stimulator 114 and the handheld graphic stimulator 110 can move freely, and the doctor can move the handheld flash stimulator 114 and the handheld graphic stimulator 110 in front of the patient's eyes. The handheld flash stimulator 114 and the handheld graphic stimulator 110 are highly flexible in use, and the doctor can flexibly move the handheld flash stimulator 114 and the handheld graphic stimulator 110 to the required position according to the needs of diagnosis. Therefore, compared with the prior art, the device 100 of the utility model is additionally provided with a handheld stimulator, and the device 100 of the utility model is suitable for testing a variety of different patients, and the device 100 has a high versatility.

[0044] The following describes how to connect the handheld stimulator to the trolley 101 .

[0045] Please refer to Figure 2 and Figure 3, the trolley 101 further includes a hook 120, the top of which can be connected to the bottom surface of the box body 115, and the hook 120 is used to hang the handheld flash stimulator 114.

When the hook 120 hangs the handheld flash stimulator 114, the handheld flash stimulator 114 and the trolley 101 are connected to each other; when the handheld flash stimulator 114 and the hook 120 are separated from each other, the handheld flash stimulator 114 can be regarded as having been removed. Hanging the handheld flash stimulator 114 by the hook 120 makes it convenient for the user to take and put the handheld flash stimulator 114. It should be noted that in other embodiments, the hook 120 can also be used to hang the handheld graphic stimulator 110, as long as the handle of the handheld graphic stimulator 110 has a hole that allows the hook 120 to pass through.

[0046] Please refer to Figure 2 and Figure 3 The trolley 101 further includes a stimulator bracket 119, which can be connected to the front edge of the table 113 or to the front edge of the box body 115. Figure 4 As shown, the stimulator bracket 119 includes a cylindrical portion 301 and a supporting portion 302. The cylindrical portion 301 is cylindrical, and a receiving space 303 is formed inside the cylindrical portion 301. The supporting portion 302 is horn-shaped, and the bottom of the supporting portion 302 is connected to the top of the cylindrical portion 301. The supporting portion 302 surrounds the receiving space 303, and the diameter of the supporting portion 302 gradually increases from bottom to top. Figure 2 As shown, for the stimulator bracket 119 on the left, its accommodating space 303 is used to accommodate a part of the handheld flash stimulator 114 (for example, accommodating the handle of the handheld flash stimulator 114), and its supporting portion 302 is used to support another part of the handheld flash stimulator 114 (for example, supporting the head of the handheld flash stimulator 114). For the stimulator bracket 119 on the right, its accommodating space 303 is used to accommodate a part of the handheld graphic stimulator 110 (for example, accommodating the handle of the handheld graphic stimulator 110), and its supporting portion 302 is used to support another part of the handheld graphic stimulator 110 (for example, supporting the head of the handheld graphic stimulator 110). If the handheld stimulator is inserted into the stimulator bracket 119, the handheld stimulator and the trolley 101 are connected to each other; if the handheld stimulator is pulled out of the stimulator bracket 119, the handheld stimulator can be regarded as having been removed. The stimulator bracket 119 can surround the handheld flash stimulator 114 or the handheld graphic stimulator 110, so as to position the handheld stimulator. The trumpet-shaped support portion 302 has a large support area, and the support portion 302 can hold the head of the handheld flash stimulator 114 or the handheld graphic stimulator 110 to prevent the handheld stimulator from falling.

[0047] like Figure 4As shown, the outer circumference of the cylindrical portion 301 is provided with a first notch 304, and the outer circumference of the supporting portion 302 is provided with a second notch 305, and the first notch 304 and the second notch 305 are connected to each other. The first notch 304 and the second notch 305 allow the cable of the handheld stimulator to pass through (the cable is not shown), so as to facilitate the user to take out the handheld stimulator from the stimulator bracket 119 and put the handheld stimulator into the stimulator bracket 119. In addition, in order to facilitate the user to take and put the handheld stimulator, the stimulator bracket 119 can be tilted forward (such as Figure 3 As shown), that is, the top end of the stimulator bracket 119 is located in front of the bottom end of the stimulator bracket 119.

[0048] like Figure 2 As shown, in this embodiment, two handheld flash stimulators 114 are provided, and the two handheld flash stimulators 114 are respectively a handheld spherical flash stimulator 109 and a handheld plane flash stimulator 108. The handheld spherical flash stimulator 109 can be placed in one of the stimulator brackets 119, the handheld graphic stimulator 110 can be placed in another stimulator bracket 119, and the handheld plane flash stimulator 108 can be hung on a hook 120. The light emitting surface (i.e., the first light emitting surface 408) of the handheld spherical flash stimulator 109 is a concave spherical surface, and the light emitting surface (i.e., the second light emitting surface 509) of the handheld plane flash stimulator 108 is a plane. Since the shapes of the light emitting surfaces of the two handheld flash stimulators 114 are different, the light emitting effects and the optical stimulations generated by the two handheld flash stimulators 114 are also different. Therefore, the present embodiment can provide more types of optical stimulation, and the device 100 can perform more test items. It should be noted that the "spherical" in "handheld spherical flash stimulator 109" means that the light-emitting surface of the stimulator is a spherical surface, and does not limit the stimulator to be spherical as a whole. Similarly, the "plane" in "handheld planar flash stimulator 108" means that the light-emitting surface of the stimulator is a plane.

[0049] The structure of the handheld spherical flash stimulator 109 is as follows Figure 5As shown. The handheld spherical flash stimulator 109 includes a first shell 401, and the first shell 401 includes a first handle portion 403 and a first head portion 402. The first handle portion 403 is used for the user to hold, and the first head portion 402 has a hemispherical shape. One end of the first handle portion 403 (which can be the top of the first handle portion 403) is connected to the first head portion 402, and the interior of the first head portion 402 has a first reflective cavity 405 and a first opening 406 that are interconnected. The first light emitting surface 408 is at least a part of the inner wall surface of the first reflective cavity 405. The handheld spherical flash stimulator 109 also includes a first light source 407, and the first light source 407 surrounds the first opening 406. The first light source 407 can be set as a ring-shaped LED light board. The first light source 407 is located in the first reflective cavity 405 and faces the first light emitting surface 408. The light emitting surface can reflect at least a part of the light emitted by the first light source 407, and at least a part of the light emitted by the first light source 407 is emitted from the first opening 406. In order to make the light emitted by the handheld spherical flash stimulator 109 softer, the light emitting surface can be set as a diffuse reflection surface (that is, the light emitting surface is not set as a mirror surface).

[0050] The handheld spherical flash stimulator 109 may further include a first cable (not shown), a portion of which is inserted into the interior of the first housing 401, and the first cable is inserted from the bottom end of the first handle portion 403 to the outside of the first housing 401. One end of the first cable is electrically connected to the first light source 407, and the other end of the first cable is electrically connected to the power supply in the box body 115, and the power supply supplies power to the first light source 407 through the first cable. In other embodiments, the handheld spherical flash stimulator 109 may also have its own power supply, which is located inside the first housing 401. In this way, the handheld spherical flash stimulator 109 does not need to be provided with a first cable, and the handheld spherical flash stimulator 109 has a larger range of movement after being separated from the stimulator bracket 119. The handheld spherical flash stimulator 109 also includes a first switch 404, which is configured as a key switch, which is installed on the first handle portion 403, and the key of the first switch 404 is exposed outside the first handle portion 403. The user can turn on the first light source 407 by pressing the first switch 404. There are different ways to turn off the first light source 407. For example, in some embodiments, after the user presses the first switch 404 once, the first light source 407 is turned on; after the user presses the first switch 404 again, the first light source 407 is turned off. For another example, in other embodiments, after the user releases the first switch 404, the first light source 407 is turned off.

[0051] The structure of the handheld planar flash stimulator 108 is as follows Figure 6As shown, the handheld planar flash stimulator 108 includes a second shell 501, a lampshade 508 and a second light source 505. The second shell 501 includes a second handle portion 502 and a second head portion 503, and the second handle portion 502 is connected to the second head portion 503, and the second handle portion 502 is used for the user to hold. The lampshade 508 is connected to the second head portion 503 to define a receiving cavity 507, and the second light source 505 is located in the receiving cavity 507. The second light source 505 faces the lampshade 508, and the second light source 505 can be set as an LED light board. The lampshade 508 is light-transmissive, and the light emitted by the second light source 505 can pass through the lampshade 508 and emit outside the second shell 501. The side surface of the lampshade 508 facing away from the receiving cavity 507 is the second light emitting surface 509. The handheld planar flash stimulator 108 also includes a second switch 504, and the second switch 504 is installed on the second handle portion 502. The user can control whether the second light source 505 is turned on by operating the second switch 504. The handheld planar flash stimulator 108 further includes a filter 506, which is located in the accommodating cavity 507 and between the second light source 505 and the lampshade 508. The filter 506 is used to filter out unnecessary light, thereby ensuring that the light emitted from the second light emitting surface 509 meets the test requirements.

[0052] The structure of the handheld graphic stimulator 110 is as follows Figure 7 As shown, the handheld graphic stimulator 110 includes a third shell 601 and a second display screen 605. The third shell 601 includes a third handle portion 603 and a third head portion 602, the third handle portion 603 is used to be held by the user, and one end of the third handle portion 603 is connected to the third head portion 602. The second display screen 605 is connected to the third head portion 602. The handheld graphic stimulator 110 also includes a third switch 604, which is installed on the third handle portion 603. The user can control whether the second display screen 605 is turned on by operating the third switch 604. The power supply method of the handheld graphic stimulator 110 and the power supply method of the handheld planar flash stimulator 108 can refer to the power supply method of the handheld spherical flash stimulator 109, which is not described in detail here.

[0053] The structure of the desktop flash stimulator 104 is as follows Figure 8As shown, the desktop flash stimulator 104 includes a box 701, a jaw support 708 and a third light source 705. The box 701 is provided with a second reflective cavity 703 and a second opening 707 which are interconnected. The inner wall surface of the second reflective cavity 703 includes a reflective surface 702, and the reflective surface 702 is a concave spherical surface. The jaw support 708 is connected to the box 701, and the jaw support 708 is located at the second opening 707. The jaw support 708 is used to support the patient's lower jaw. The third light source 705 surrounds the second opening 707, and the third light source 705 is located in the second reflective cavity 703. The reflective surface 702 can reflect at least a portion of the light emitted by the third light source 705, and make at least a portion of the light emitted by the third light source 705 emitted from the second opening 707. Since the desktop flash stimulator 104 reflects light through the spherical surface, the light emitting effect of the desktop flash stimulator 104 is similar to the light emitting effect of the handheld spherical flash stimulator 109. In addition to allowing light to pass through, the second opening 707 can also accommodate the patient's head. The patient's head can extend to the second opening 707, and the patient's lower jaw can be placed on the jaw support 708, and then the patient can look into the second reflective cavity 703 to receive the stimulation of light. In order to make the light softer, the reflective surface 702 can be set as a diffuse reflection surface. The box 701 also includes a baffle 706, the top of the baffle 706 is connected to the edge of the opening, and a part of the baffle 706 extends into the second reflective cavity 703. When the patient's head is at the second opening 707, the baffle 706 is roughly located in front of the patient's forehead, and the baffle 706 is used to block the light source so that the light emitted by the light source does not directly shine into the patient's eyes, thereby preventing damage to the patient's eyes. The flash stimulator also includes a camera 704, which is used to collect images of the patient's eyes, and the image can be used as one of the doctor's diagnosis bases.

[0054] like Figure 1 As shown, the electrophysiological eye diagnosis device 100 also includes a jaw support bracket 103, at least a portion of which is located above the top surface of the table top 113, and the jaw support bracket 103 can move relative to the table top 113 to switch between the first position 201 and the second position 202. In this embodiment, the jaw support bracket 103 can slide relative to the table top 113. Specifically, the jaw support bracket 103 includes a slider 116, the trolley 101 includes a slide rail 112, the slide rail 112 is arranged on the bottom surface of the table top 113, and the slider 116 is connected to the slide rail 112. In this way, the jaw support bracket 103 can slide along the slide rail 112. In other embodiments, the movement mode of the jaw support bracket 103 relative to the table top 113 can also be set to rotation. Fig. 9 , the chin support bracket 103 is in the first position 201; Fig.10In the embodiment, the chin support bracket 103 is in the second position 202. When the chin support bracket 103 is in the first position 201, the chin support bracket 103 is located in front of the display screen, and the chin support bracket 103 is arranged opposite to the display screen; when the chin support bracket 103 is in the second position 202, the chin support bracket 103 and the display screen are staggered.

[0055] In the present invention, the first display screen 117 is oriented from the back to the front. The chin support bracket 103 and the first display screen 117 are arranged relative to each other, which means that at least a part of the projection of the chin support bracket 103 from the front to the back can fall on the first display screen 117. The chin support bracket 103 and the first display screen 117 are staggered, which means that the projection of the chin support bracket 103 from the front to the back is completely outside the edge of the first display screen 117.

[0056] When performing certain tests, the user (patient or doctor) can first adjust the chin support bracket 103 to the first position 201, and then the patient can sit closer to the desktop graphic stimulator 102 and lean his head against the chin support bracket 103 to observe the graphics displayed on the first display screen 117. It should be noted that the chin support bracket 103 is hollow, and when the patient's head leans against the chin support bracket 103, the patient's eyes are located inside the hollow part, and the chin support bracket 103 does not block the patient's sight.

[0057] When performing other tests, the patient needs to sit at a position far away from the desktop graphic stimulator 102. At this time, the patient is far away from the chin support 103, and the user does not use the chin support 103. At this time, in order to prevent the chin support 103 from obstructing the patient from observing the first display screen 117, the user can adjust the chin support 103 to the second position 202.

[0058] like Figure 1 As shown, the device 100 also includes a main display 105 and a printer 107. The main display 105 is installed on the top surface of the table 113, and the printer 107 is fixed to the trolley 101. The main display 105 can display the data collected by the electrodes attached to the patient's head, and the doctor can view the patient's test data through the main display 105. The printer 107 can print the patient's report. The device 100 also includes a keyboard tray 106, which can be movably installed on the side of the table 113, and the keyboard tray 106 and the main display 105 are located on the same side of the table 113. The keyboard tray 106 can be used to carry a keyboard and a mouse. When the keyboard tray 106 is not needed, the keyboard tray 106 can be flipped upward to the position as shown in the figure. Figure 1 when the user needs the keyboard tray 106, the keyboard tray 106 can be flipped downward to a horizontal state.
