The lower jaw supporting assembly is arranged at the second end, and the lower jaw supporting assembly is detachably connected with the base; a power source structure, a control structure, an air injection assembly and a feeling stimulation assembly are arranged in the measuring body, the control structure, the air injection assembly and the feeling stimulation assembly are connected with the power source structure through wires, and the control structure is in data connection with the air injection assembly and the feeling stimulation assembly through wires.

Description

A multisensory corneal perception measurer technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multisensory corneal perception measuring device. Background technique [0002] The cornea is covered with nerve endings and is the most sensitive area of ​​the human body. Nerve endings from the main branch of the trigeminal nerve in the cornea The upper layer bifurcates and forms a dense network of nerve endings, ending in the corneal epithelial cells. As a result, the cornea becomes extremely sensitive, even to The foreign body that is about to hit the cornea can be "predicted", so as to avoid it in advance (close eyes, dodge, etc.). [0003] Corneal perception is normal, and reflex blinking occurs immediately upon contact with the cornea. If the reflexes are sluggish, the perception is Decreased, the sensation disappeared completely, and there was no manifestation after contact with the cornea. Decreased...
