Description

Technical field

[0001] The present invention belongs to the technical field of medical device, and more particularly to a retinal under fluid drainage device and a collector. Background technique

[0002] In the clinical work of ophthalmology, retinal disengagement (bleeding or pore sources) is a serious symptom of vision, these symptoms can be found in some eye trauma, inflammation, and internal eye surgery, and remove the retina as a test specimen, available In further laboratory testing, it is a potential disease diagnosis, identifying diagnosis and development direction.

[0003] At present, the function of the retinal liquid drainage device on the market is mostly to achieve retinal discharge, such as the Chinese patent (CN203370018U) discloses a retinal subtracheal drainage valve composed of a drain tube, a negative pressure valve, a fixed ring, and an implantation. It is necessary to use 5ml needle to pierce the sclera wall, which is fixed by the drainage valve and the eye...
