Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0028] The present application embodiment provides a baffle for a slit lamp, see Figure 1 and Figure 2, including a plate body 10, which is a sheet structure with a certain thickness. The plate body 10 is provided with a through hole 101 in the thickness direction, and a crack portion 102 is provided on one side edge of the plate body 10 extending in the direction of the through hole 101. The crack portion 102 can be regarded as a region where the plate body 10 can be separated from each other by shearing along one side edge of the plate body 10 toward the through hole 101. The crack portion 102 is configured so that after the plate body 10 moves the objective lens barrel 2 of the slit lamp relatively along the crack portion 102 into the through hole 101, the crack portions 102 of the plate body 10 are attached to each other, so that the plate body 10 is fixed on the outside of the objective lens barrel 2.

[0029] In the above embodiment, when the plate body 10 is hung on the objective lens barrel 2, the slit portion 102 of the plate body 10 is separated, and then the plate body 10 is moved so that the objective lens barrel 2 passes through the slit portion 102 and reaches the through hole 101 of the plate body 10, and then the slit portion 102 of the plate body 10 is attached. After the plate body 10 is hung on the objective lens barrel 2, the saliva droplets between the medical staff and the patient can be prevented from splashing each other.

[0030] In some embodiments, at least a portion of the plate 10 is made of a transparent material, and the area where the transparent material is located forms an observation window, which facilitates medical personnel to determine the patient's condition during the test, including whether the patient's body position is appropriate, whether the eyes are aligned, etc. At least a portion of the plate 10 is made of an elastic material, so that after the objective lens barrel 2 of the slit lamp is relatively moved along the slit portion 102 into the through hole 101, the slit portions 102 of the plate 10 can fit each other.

[0031] In some examples, a portion of the through hole 101 of the plate body 10 on a side opposite to the crack portion 102 is provided with elastic material, so as to ensure that the crack portion 102 of the plate body 10 can resume the state of being in close contact with each other after being separated.

[0032] In other examples, the entire plate body 10 may be made of a material having a certain degree of elasticity.

[0033] In some other examples, the transparent area of ​​the board body 10 may be made of transparent plastic material.

[0034] Preferably, the entire board 10 can be made of transparent hard plastic, which can meet the requirements of transparent materials and have a certain elasticity, so that the crack parts 102 of the board 10 can fit together again after being separated. In a specific application scenario, when the board 10 is normally held in front of the operator's body, in the process of separating the crack part 102, the board 10 can be held at the areas on both sides of the crack part 102, and then one side is moved toward the direction close to the body and the other side is moved away from the body, instead of directly moving the two sides of the crack part 102 of the board 10 in directions away from each other, which can effectively avoid the crack part 102 of the board 10 from damaging the board 10 during the separation process.

[0035] In some embodiments, the parts where the crack parts 102 of the plate body 10 are attached to each other are made of magnetic materials. The provision of the magnetic materials can facilitate the separation and attachment of the crack parts 102 of the plate body 10.

[0036] In some of these examples, see Figure 2 The board body 10 is made of transparent material as a whole, such as a transparent plastic board, and at least a part of the board body 10 is provided with an Amsler grid 103. In a specific application scenario, when a patient looks at the Amsler grid 103 on the board body 10, because this part of the board body 10 is made of transparent material, the patient's line of sight can see the clothes of the medical staff through the transparent board body 10, and the clothes of the medical staff are usually white. At this time, with a white background and the black Amsler grid 103 lines set on the board body 10, the patient's macular degeneration can be screened. The screening of macular degeneration is part of the conventional ophthalmic examination. Through the above setting, this part of the examination can be integrated, thereby reducing the steps of ophthalmic examination and improving the efficiency of ophthalmic examination.

[0037] In some of these examples, see Figure 3 , at least a part of the plate 10 is provided with a red-green combination pattern 104. Through the setting of the red-green combination pattern 104, it is possible to detect whether the patient has red-green color blindness. Similar to the detection of macular degeneration, red-green color blindness is a routine item in ophthalmological examination. Through the above setting, the steps of ophthalmological examination can be reduced and the efficiency of ophthalmological examination can be improved.

[0038] In some embodiments, the distance ratio between the through hole 101 of the plate body 10 and the edges on both sides is greater than 2:1; the crack portion 102 is provided between the through hole 101 of the plate body 10 and the edge close to the through hole 101. Through the above arrangement, when the plate body 10 is placed, the through hole 101 of the plate body 10 is provided at the upper position of the plate body 10 with the horizontal center line of the plate body 10 as the reference. With this arrangement, when the plate body 10 is made of the same material, the upper part of the plate body 10 will be lighter than the lower part due to the provision of the through hole 101. Under the action of gravity, the plate body 10 will naturally sag and will not rotate. The crack portion 102 is provided between the through hole 101 of the plate body 10 and the edge close to the through hole 101, which can reduce the length of the crack portion 102 and facilitate production.

[0039] In some examples, when the crack portion 102 is set starting from the upper edge of the plate body 10, in order to avoid the fulcrum of the plate body 10 and the objective lens barrel 2 contacting the crack portion 102, causing the crack portion 102 to gradually separate, the crack portion 102 can be set at an angle, that is, not in the vertical direction.

[0040] In some embodiments, the aperture of the through hole 101 of the plate body 10 is no more than 3 cm larger than the diameter of the slit lamp objective lens barrel 2. The aperture of the through hole 101 of the plate body 10 is no more than 3 cm larger than the diameter of the slit lamp objective lens barrel 2, but no more than 3 cm, so that the plate body 10 can be in closer contact with the slit lamp objective lens barrel 2 through the through hole 101, avoiding the shaking of the plate body 10. In a specific example, the through hole 101 of the plate body 10 can be set to a circular shape.

[0041] In other embodiments, no matter how large the hole pitch of the through hole 101 of the plate body 10 is, as long as the aperture of the through hole 101 is larger than the diameter of the slit lamp objective lens barrel 2, the top of the hole wall of the through hole 101 of the plate body 10 contacts the objective lens barrel 2 under the action of gravity, thereby completing fixation.

[0042] In some embodiments, the plate body 10 is set to be rectangular, and the corners of the plate body 10 are set to be arc-shaped. The plate body 10 is set to be rectangular, which is convenient for the processing steps of production and manufacturing, can effectively reduce production investment, and improve economic efficiency. The corners of the plate body 10 are set to be arc-shaped, which can prevent the plate body 10 from scratching people.

[0043] In some of the embodiments, the size of the plate 10 may be 30*25 cm.
