Abstract
Description
Technical Field
[0001] The present invention relates to a fixing bracket / chair for examination, in particular to an ophthalmic examination fixing device used when the patient is under sedation and undergoing ophthalmic examination. Background Art
[0002] An eye exam is usually done with the person sitting or standing with their head still, and the eyes are examined.
[0003] For patients who are unable to cooperate, such as children, patients who cannot control their behavior, etc., it is sometimes impossible to complete the examination relying on the cooperation of the patients. In this case, certain sedatives will be administered to the patients to keep them in a sedated state so that the relevant examinations can be completed.
[0004] However, because patients cannot control their body movements and postures when they are in a sedated state, they cannot sit or stand for examinations on their own. Existing examination chairs cannot effectively restrain and fix the human body. Therefore, the current common practice is for the patient's family to help fix the patient's body and then cooperate with the doctor to perform the examination. This examination method is not only labor-intensive, but also has a poor fixation effect.
[0005] Therefore, the purpose of the present invention is to develop a fixed support / chair suitable for examination under sedation, which can effectively restrain and fix the patient's body, especially the patient's head, so as to be suitable for ophthalmic examination under sedation. Summary of the Invention
[0006] The ophthalmic examination fixation device under sedation of the present invention achieves three-dimensional spatial positioning of the patient's body in a sedated state by fixing the head of the head fixation device and fixing the torso of the limb adjustment fixation device.

[0008] A. The head adjustment and fixation device 1 includes a mandibular adjustment and fixation mechanism 11 and a back-of-head adjustment and fixation mechanism 12; the mandibular adjustment and fixation mechanism 11 and the back-of-head adjustment and fixation mechanism 12 work together to adjust the three-dimensional posture of the head; the head adjustment and fixation device 1 is mounted on the limb adjustment and fixation device 2 and / or the base 3;
[0009] B. The limb adjustment and fixing device 2 includes an underarm lifting mechanism 21, and the limb adjustment and fixing device 2 capable of lifting the human torso is installed on the base 3;
[0010] C. The coordinated action of the head adjustment and fixing device 1 and the limb adjustment and fixing device 2 realizes the spatial three-dimensional posture adjustment and positioning of the human body trunk and head.
[0011] The coordinated action of the mandibular adjustment and fixation mechanism 11 and the back-of-the-head adjustment and fixation mechanism 12 can fix the head's three-dimensional spatial position. The patient places their arms on the underarm support mechanism 21, which lifts and secures the torso.
