In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figures 1 to 5 As shown, this embodiment provides a shading device for pupil observation, including: a body, which is a frame 1 structure with both the top and bottom surfaces open, and is used to cover around the patient's eyes. For example, the frame 1 can be made of opaque plastic material. The size of the frame 1 is slightly larger than the frame of sunglasses, which is convenient for medical staff to insert their fingers into the left chamber 101 or the right chamber 102 to open the patient's eyelids. A side light shield 4 is arranged in the body, and the side light shield 4 divides the space in the body into independent left chambers 101 and right chambers 102; a switching light shield 8 is movably arranged on the top surface of the body. When the switching light shield 8 moves to the first position, the top of the left chamber 101 is blocked and the top of the right chamber 102 is open. When the switching light shield 8 moves to the second position, the top of the right chamber 102 is blocked and the top of the left chamber 101 is open.

[0042] The light-shielding device for pupil observation provided in this embodiment divides the space inside the main body into an independent left chamber 101 and a right chamber 102 by means of the side light-shielding plate 4, separating the two eyes. The switching light-shielding plate 8 can be used to switch and block the eyes, so that when irradiating one eye, the other eye can be blocked to prevent the unexamined eye from being accidentally irradiated. Moreover, there is no need for a nurse to manually block the unexamined eye, which facilitates the pupil observation operation during physical examination and saves manpower.

[0043] As Figure 2 shown, the light-shielding device for pupil observation further includes a displacement and switching assembly 7. The displacement and switching assembly 7 includes a horizontal sliding groove 71 and a horizontal sliding block 72. Horizontal sliding grooves 71 are provided on both the front side wall and the rear side wall of the main body, and horizontal sliding blocks 72 are provided on both the front side wall and the rear side wall of the switching light-shielding plate 8. The horizontal sliding blocks 72 are slidably clamped in the horizontal sliding grooves 71. With such a setting, the horizontal sliding groove 71 restricts the sliding distance of the horizontal sliding block 72, and the switching light-shielding plate 8 can block the left eye or the right eye as it slides along with the horizontal sliding block 72, realizing separate observation of the pupils.

[0044] Among them, the light-shielding device for pupil observation further includes a buffer assembly 3. The buffer assembly 3 includes a vertical sliding groove 31, a column 32, an elastic member 33, and a longitudinal sliding block 34. Vertical sliding grooves 31 are provided on both the front side wall and the rear side wall of the main body. The column 32 is arranged in the vertical sliding groove 31. For example, the bottom of the column 32 can be adhered to the bottom of the vertical sliding groove 31. The longitudinal sliding block 34 is connected to the side light-shielding plate 4 and is sleeved on the column 32. The elastic member 33 is sleeved on the column 32 and is used to provide a force for pressing the side light-shielding plate 4 against the bridge of the nose. For example, the elastic member 33 can be a spiral spring, one end of which can abut against the top wall of the vertical sliding groove 31, and the other end can abut against the top of the longitudinal sliding block 34. The spiral spring presses the longitudinal sliding block 34 downward along the column 32, so that the side light-shielding plate 4 has a tendency to move downward, causing the bridge-of-nose contact strip 5 to press against the top of the bridge of the nose and preventing light leakage from the top of the bridge of the nose.

[0045] As Figure 3 shown, the light-shielding device for pupil observation further includes a bridge-of-nose contact strip 5, which is arranged at the bottom of the side light-shielding plate 4. The bottom surface of the bridge-of-nose contact strip 5 is a curved surface structure adapted to the contour of the patient's bridge of the nose. For example, the bridge-of-nose contact strip 5 can be a convex arc structure.

[0046] As Figure 4 、 Figure 5As shown in the figure, the light-shielding device for pupil observation further includes a light-blocking component 6, which includes a mounting bracket 61, a rotating shaft 62, and a buffer light-blocking sleeve 63. Mounting brackets 61 are respectively arranged at the front and rear ends of the top of the side light-blocking plate 4. A rotating shaft 62 is rotatably connected between the two mounting brackets 61. A buffer light-blocking sleeve 63 is fixedly sleeved on the outer peripheral side of the rotating shaft 62. The buffer light-blocking sleeve 63 is in rolling connection with the bottom of the switching light-blocking plate 8. Since the side light-blocking plate 4 moves up and down with the longitudinal slider 34, the mounting bracket 61 and the rotating shaft 62 also move up and down. The buffer light-blocking sleeve 63 can be a sponge sleeve, which can block the gap between the side light-blocking plate 4 and the switching light-blocking plate 8, and can also deform with the up and down movement of the side light-blocking plate 4. When the side light-blocking plate 4 moves, the top of the buffer light-blocking sleeve 63 is always in rolling connection with the bottom of the switching light-blocking plate 8 to ensure the sealing performance.

[0047] As Figure 3 shown in the figure, a nose bridge groove 12 for accommodating the patient's nose bridge is provided on the bottom surface of the main body, and a nose bridge cushion strip 10 is arranged in the nose bridge groove 12. A cheek groove 11 for accommodating the patient's cheeks is provided on the bottom surface of the main body, and a cheek cushion strip 13 is arranged in the cheek groove 11. For example, nose bridge grooves 12 are respectively formed at the front and rear sides of the center of the bottom of the frame body 1, and a nose bridge cushion strip 10 is adhered in the nose bridge groove 12. Cheek grooves 11 are respectively formed on both sides of the bottom of the frame body 1, and a cheek cushion strip 13 is adhered in the cheek groove 11. The cheek groove 11 cooperates with the upper side of the patient's cheek, and the nose bridge groove 12 cooperates with the nose bridge. The nose bridge cushion strip 10 and the cheek cushion strip 13 prevent the frame body 1 from pressing indentations on the patient's face. For example, both the nose bridge cushion strip 10 and the cheek cushion strip 13 can be made of silicone strips, which can keep the face comfortable when contacting the patient's face. The nose bridge groove 12, the nose bridge cushion strip 10, the cheek groove 11, and the cheek cushion strip 13 together form a face-fitting component, which ensures better fitting of the frame body 1 with the patient's face during use.

[0048] The light-shielding device for pupil observation further includes a clamping component 2, which includes a deformation plate 21 and a gasket 22. Deformation plates 21 are arranged at the bottoms of the left and right side walls of the main body, and the forehead sides of the patient are clamped by the deformation plates 21 to fix the main body on the patient's face. The gasket 22 is arranged on the inner side wall of the deformation plate 21. For example, the gasket 22 can be made of silicone material to protect the patient's forehead and prevent the deformation plate 21 from clamping the patient's forehead uncomfortably. For example, the deformation plate 21 can be made of deformable plastic material, which is convenient to be clamped on the patient's forehead through plastic deformation to keep the position of the frame body 1 stable on the patient's face.

[0049] A buckle groove 9 is arranged on the plate surface of the switching light-blocking plate 8. With such a setting, it is convenient to pull the switching light-blocking plate 8 to move left and right through the buckle groove 9, providing a grip for moving the position of the switching light-blocking plate 8.

[0050] During use, the housing 1 is attached to the patient's eyes through the facial fitting component and clamped on both sides of the forehead by the clamping component 2, and the bridge contact strip 5 contacts the top of the nose bridge; the side light blocking plates 4 separate the two eyes, and the buffer component 3 enables the bridge contact strip 5 to be in close contact with the top of the nose bridge, avoiding a gap between the bridge contact strip 5 and the top of the nose bridge; the switching light blocking plate 8 can switch to block the eyes through the displacement switching component 7. When examining the left eye, move the switching light blocking plate 8 to the right to block the patient's right eye, and vice versa; the light blocking component 6 can block the gap between the bottom of the switching light blocking plate 8 and the top of the side light blocking plate 4, preventing light from shining on the other eye through the gap when examining one eye.

[0051] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
