Clamp for nasolacrimal sac occlusion during administration of ocular medication

摘要

A clamp is placed over the bridge of the nose to apply pressure over the fossa of the nasolacrimal sac, prior to ocular medication to thereby seal the nasolacrimal sac and prevent drainage of medicament away from the eye. The clamp can be embedded in a flexible molded positioning device which has been molded to fit the shape of the bridge of the nose. In an improved embodiment the embedded clamp in a flexible molded positioning device is attached to a modified eyeglass frame. In a further embodiment a band to go around the back of the head or around the ears can be attached to the clamp.
