Medical device for long-term preservation of the cornea, or medical device for in vitro experiments of human or animal cornea

摘要

A device (1) for storing a corneal sample (3), comprising means (2, 4, 5) for receiving and entrap the corneal specimen (3), the means (2, 4, 5) being a corneal specimen (3) In a layout providing means for receiving and entrapment (2, 4, 5), a device connected to means for generating a pressure gradient using the overpressure on the endothelium side and means for circulating the storage medium (1). The means (2, 4, 5) for receiving and entrap the corneal specimen (3) is a separate endothelial chamber (18) and epithelial chamber (19) in which the storage medium can be circulated by overpressure in the endothelial chamber (18). ) Entraps the scleral ciliary zone (3b) that tightly surrounds the cornea (3a). The intermediate component (2) and the endothelial lid (4) are for a storage medium connected to means for circulating the storage medium by overpressure in the endothelial chamber and creating a pressure gradient between the endothelial chamber and the epithelial chamber. An inlet orifice (7a, 11a) and an outlet orifice (7b, 11b) are provided.
