Description

Wearable eyelid closure training device and training method Technical Field The invention relates to a wearable eyelid closure training device and a training method. Background Eyelid closure is important for protecting the cornea, maintaining ocular surface wetting, promoting tear distribution, and removing foreign bodies. Eyelid insufficiency (rabbit eye disease) is commonly observed in facial paralysis (e.g., belleville paralysis, after auditory neuroma surgery), myasthenia gravis, eyelid trauma or after plastic surgery, etc., and can lead to corneal exposure, dryness, ulcers, infections, and even vision in severe cases. At present, rehabilitation nursing and training means aiming at eyelid closing function mainly comprise: 1. Passive intervention means such as applying medical tape to the upper and lower eyelids to force closure, or wearing wet room mirrors, eye masks, etc. Such methods provide only physical coverage and protection from corneal exposure, but completely exclude active orbicular muscle contractile movements in the patient, which may lead to disuse atrophy of muscles over prolonged periods of time, and do not contribute to active recovery of neuromuscular function. 2. The patient is instructed to consciously perform eye opening and closing actions.
