Abstract
The invention discloses a device for treating the blocking of eye meibomian gland. The device comprises a body; the body is provided with at least one eyeball accommodating cavity and at least one rolling extrusion device arranged in the cavity; and the rolling extrusion device is used for vertically rolling and extruding eyelid to make a melted, loosen or softened meibomian gland blockage substance flown out of an eye. The device adopts an indirect heating mode of air conduction to ensure more uniform heating on the eyelid and the surrounding of the eyelid, the phenomenon of discomfort eyelid part and the surrounding is avoided because the local temperature is too high due to direct heating on the eyelid by a heating body, and the comfortable degree of eyelid skin is improved by a rolling mode. Moreover, the rolling extrusion device can be detachably connected and is convenient to clean and sterilize.
Description
Technical field
The present invention relates to a kind of ocular disease therapy equipment, be specifically related to a kind of device for the treatment of blocking of eye meibomian gland.
Background technology
The tarsal glands of the eyelid of human eye secretion oils and fats is for eye and eyelid provide lubricated.When these glands stop up because of various mechanism, just cause " xerophthalmia ".One of reason of xerophthalmia is meibomian gland dysfunction (MGD), this obstacle be characterized as in the tarsal glands or it surperficially has tamper to hinder normal lipid secretions to flow out.Tamper is removed one of the important means of the xerophthalmia that is this reason for the treatment of.
Summary of the invention
The object of the present invention is to provide a kind of device at the treatment blocking of eye meibomian gland, to solve the above-mentioned problems in the prior art.
