Embodiment 1

[0052] From October 2016 to October 2017, 30 patients who underwent deep lamellar keratoplasty in Shandong Provincial Eye Hospital were collected. figure 1 Dry corneal material produced by the desiccator shown to maintain corneal shape.

[0053] After adjusting the indoor temperature to 21°C and humidity to 45%, irradiate the indoor ultraviolet lamp for 30 minutes;

[0054] 75% alcohol to wipe the inner wall of the dryer;

[0055] Turn on the first ultraviolet lamp tube, the second ultraviolet lamp tube and the circulation fan in the dryer, the input power of the circulation fan is 25W, the rated speed is 2800r / min, the power of the first ultraviolet lamp tube and the second ultraviolet lamp tube 6W and 4W respectively, the irradiation time of the first ultraviolet lamp and the second ultraviolet lamp is 30min;

[0056] Take the corneal sample stored in the DX corneal medium-term preservation solution for more than 7 days, absorb the preservation solution vertically with a d...

Abstract

The invention provides a dryer for maintaining the cornea shape and belongs to the field of corneal shape maintenance. The dryer comprises a sealed working box, the sealed working box comprises a circulating fan, a circulating air duct, a dust filter screen, a drying box, a fixed platform surface, a first ultraviolet lamp tube and a renewable moisture absorber arranged sequentially in the sealed working box, a primary effect filtering sponge is arranged in the circulating fan, and positioning holes and an air vents are arranged in the drying box, 304 stainless steel beads are arranged the positioning holes for placing the cornea, and a second ultraviolet lamp tube and an air outlet are arranged on the inner wall of the sealed working box. In the invention, the positioning holes are arranged in the dryer for placing the 304 stainless steel beads, and a cornea sample is placed on the 304 stainless steel bead during drying, thereby better maintaining the cornea shape and solving the problem of shrinkage and deformation of the cornea sample in the drying process.

Description

technical field [0001] The invention relates to the technical field of corneal shaping, in particular to a dryer for maintaining corneal shaping and a method for maintaining corneal shaping. Background technique [0002] Corneal blindness is the second leading cause of blindness in my country. At present, there are about 4 million corneal blind people in my country, and more than 100,000 new cases are added every year. Corneal transplantation is the most effective and only way to treat corneal blindness. However, due to the limited number of corneal donations in my country, corneal materials are still in short supply. Therefore, preservation of corneal material is an important guarantee for corneal transplantation. When the source of fresh cornea is limited and cannot meet clinical needs, good corneal preservation can make full use of limited corneal resources. [0003] At present, the storage methods of inactive corneal materials are mainly glycerol storage and dry storag...
