Abstract

The invention relates to a cornea stainer. The cornea stainer comprises a carrier and a packaging bag. Cotton yarn or a cotton thread is adopted as the carrier, dye A is adsorbed on the carrier, and the dye A is sodium fluorescein. The carrier is placed in the packaging bag. Preferably, dye B is further adsorbed on the carrier, and the dye B is methyl blue or placenta blue or lissamine green. Morepreferably, the mass ratio of the dye A to the dye B is 1:1. According to the cornea stainer, the cotton yarn or the cotton thread replaces filter paper, and the defects that the dyeing effect of thefilter paper is poor, and the dyeing dosage carried by the carrier is small, specially the defect that when two or more dyeing agents are used for mixed dyeing, the dyeing effect of the filter paperis poor.

Description

technical field [0001] The invention belongs to ophthalmology clinical detection supplies, in particular to a corneal stainer. Background technique [0002] Among the many examinations in ophthalmology, corneal staining is one of the most commonly used methods for checking corneal damage. The products currently on the market for corneal staining use filter paper to soak the dye fluorescein, put it into the eyes after drying, and use tears to make the fluorescein Dissolves and stains the injured cornea. [0003] The fluorescent dyed filter paper has the following disadvantages: 1), the fluorescent dyed filter paper has damage to the cornea; 2), the filter paper is easily broken in the eye after being put into the eye for dyeing; 3), the production process is complicated, and the environment is easily polluted. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies of the prior art and provide a corneal dyer. [0005] The present in...
