摘要:
A device is used to temporarily compress the nasolacrimal ducts to reduce outflow of eyedrop during and after eyedrop instillation. The device is to be hand bended to snuggly fit any adult head sizes with any facial features so that the nose pads may apply firm pressure over the nasal aspect of the orbital rim where nasolacrimal ducts lay underneath the skin. The pressure delivered by the device is consistent and is controllable by the user. The device includes failure mechanism to protect against excessive pressure. By keeping eyedrops in the eye, medication absorption is improved and bitter taste due to eydrop outflow is reduced or eliminated. It alleviates the burden of manual nasolacrimal occlusion currently practiced by eye patients and is best for frequent, multiple eyedrops users.
