[0021] This embodiment describes an ophthalmic device with an infection-proof structure, such as... Figures 1 to 4 As shown, it includes a horizontally set base plate 7, and two screws 3 are vertically fixed to the top of the base plate 7. The lower ends of the two screws 3 are fixed to the top of the base plate 7, and the two screws 3 are distributed in parallel from left to right.

[0022] A headband 10 is horizontally arranged between the screws 3 and slides up and down with them. The headband 10 restricts the patient's forehead and has a certain fixing effect on the patient. It avoids the patient's head shaking violently when the light shines on the eyes during the examination. The headband 10 moves up and down along the length of the screws 3. The height of the headband 10 is adjusted according to the patient's body shape to match the patient's forehead. The headband 10 is made of plastic and has a certain degree of flexibility. After the patient's head is attached to the headband 10, the headband 10 bends and attaches to the patient's forehead.

[0023] The headband 10 has a detachable non-woven fabric 11 inside, which separates the patient's forehead from the headband 10 to avoid cross-infection caused by different patients using the headband 10. The detachable non-woven fabric 11 is easy to replace. Alternatively, absorbent cotton can be used, which can absorb the sweat produced on the patient's forehead and improve the comfort during the examination.

[0024] A pad 8 is horizontally fixed to the top of the base plate 7 between the two screws 3. The pad 8 is fixed to the top of the base plate 7. The top of the pad 8 has an arc-shaped groove. When the patient is examined, the chin is placed in the groove to support the patient's head.

[0025] A pad 18 is provided on the top of the pad 8. The pad 18 separates the patient's chin from the pad 8. Cross-infection can be avoided by changing the pad 18 if different patients use the pad 8.

[0026] Fixing blocks 14 are fixed to the left and right ends of the top of the pad 8. The left fixing block 14 is fixed to the left end of the top of the pad 8, and the right fixing block 14 is fixed to the right end of the top of the pad 8. Each fixing block 14 has a through groove that connects the left and right sides. The two ends of the pad paper 18 are inserted into the corresponding through grooves. The pad paper 18 is laid flat in the groove at the top of the pad 8. The left end of the pad paper 18 is inserted into the left through groove, and the right end is inserted into the right through groove. The top of the fixing blocks 14 is open downwards. A through hole communicating with the through groove is provided, and a sliding rod 15 is vertically and independently installed in each through hole. The sliding rod 15 slides up and down along the depth direction of the through hole. After the lower end of the sliding rod 15 enters the through groove, a pressure plate 17 is horizontally fixed to it. The pressure plate 17 is horizontally fixed to the lower end of the sliding rod 15. When the sliding rod 15 moves, it drives the pressure plate 17 to move up and down in the through groove. A spring 16 is fitted on each sliding rod 15 between the pressure plate 17 and the wall of the through groove. The lower end of the spring 16 is fixed to the top of the pressure plate 17, and the upper end is fixed to... At the top inner part of the fixing block 14; in the natural state of the spring 16, the pressure plate 17 presses the pad paper 18 tightly against the top of the pad plate 8. The spring 16 continues to push the pressure plate 17 downward, and the pressure plate 17 presses both ends of the pad paper 18 into the through groove. This section constitutes a connecting assembly for quick replacement of the pad paper 18. When using the connecting assembly, the pad paper 18 is laid flat in the groove at the top of the pad plate 8. The two sliding rods 15 are pulled up, and the spring 16 contracts under force, inserting both ends of the pad paper 18 into the through groove. The sliding rods 15 are released, and the spring 16 returns to its original shape after losing force, pressing both ends of the pad paper 18 tightly against the top of the pad plate 8. When replacing the pad paper 18, the sliding rods 15 are pulled up to remove the pad paper 18 from the through groove. Of course, the connecting assembly can also use a telescopic rod. The extension and retraction of the telescopic rod drives the pressure plate 17 to move up and down. The upper end of the telescopic rod is fixed to the top inner part of the fixing block 14, and the lower end of the telescopic rod is fixed to the pressure plate 17. The telescopic rod is existing technology and generally uses an electric push rod.

[0027] In this embodiment, the patient's head is inserted between the two screws 3, and the chin is placed on the top of the pad 8. The chin is separated from the pad 8 by the pad paper 18. The height of the headband 10 is adjusted according to the patient's body shape so that the forehead rests on the headband 10. The pad 8 helps to limit the patient's head position. The non-woven fabric 11 separates the patient's forehead from the headband 10. After the patient's examination, the used pad paper 18 is quickly replaced by the connecting component. At the same time, the used non-woven fabric 11 is removed from the headband 10 and replaced with a brand new non-woven fabric 11 to avoid cross-infection between different patients.

[0028] Example 2
