Title:
SELF-SUCTION CORNEAL SUCTION RING
Document Type and Number:
WIPO Patent Application WO/2016/101251
Kind Code:
A1
Abstract:
Disclosed is a self-suction corneal suction ring, comprising a corneal ring (1) and a self-suction ring (2) located at the bottom of the corneal ring (1). The self-suction ring (2) comprises a semi-arc self-suction ring body, which just fits the edge of corneosclera, and automatically generates suitable vacuum suction by a rebound effect after pushing the self-suction ring (2) downward. Meanwhile, the self-suction ring (2) is made of soft rubber. When the suction surface of the soft rubber forms vacuum suction, it can reduce patient discomfort. The self-suction corneal suction ring is lightweight in structure, can be attached by suction to the edge of corneosclera effectively, ensure drug penetration in the corneal ring (1), and prevent waste caused by drug liquid flowing out of the eye.
