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

A kind of device for the treatment of blocking of eye meibomian gland

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.

Technical scheme provided by the invention is as follows:

A kind of device for the treatment of blocking of eye meibomian gland, it comprises:

One body, it is provided with at least one cavity that holds eye, and

At least one rolling extrusion device that is installed in the cavity, it from top to bottom to the eyelid rolling extrusion, makes thawing, lax or softening obstruction of tarsal glands thing flow out from eye when rolling.

Described rolling extrusion device comprises that one can be around the roller from the axle rotation, does not contact with eyelid during its rotation; Roller is provided with at least one and this roller axle center out-of-alignment squeegee roller, and this squeegee roller contacts also rolling extrusion eyelid rotating with roller to the position of eye one side with eyelid, and this squeegee roller can rotate around Pivot Point Center.

Be connected to detachable the connection between described squeegee roller and the roller.

Described squeegee roller flexibly is installed on the roller.

Axially be provided with at least one container cavity on the roller, described squeegee roller is installed in the container cavity by an elastic support; Described elastic support is staple shape, and its side that is provided with leg is towards the setting of container cavity outside direction, and opposite side arranges towards the container cavity internal direction; Establish respectively one on the leg of two ends for the groove that inserts the squeegee roller wheel shaft, the opposite side relative with leg is provided with flexure strip, this flexure strip and container cavity inwall resilient abutment; Be provided with in addition locating hole at least one and that container cavity communicates on this roller, establish a positioning block in this locating hole, it inserts the side that elastic support is provided with leg.

Groove on the leg of described elastic support is provided with than the little elastic opening of squeegee roller wheel shaft diameter, and described squeegee roller wheel shaft can be pressed into this groove by this elastic opening or therefrom take out.

Described squeegee roller is made by flexible material, and diameter is dwindled to the centre gradually by two ends.

Described body is picture frame shape, and it comprises: a shell, an inner shell and are used for the seal closure with cavity and eye sealing.

Be provided with heater in the cavity of described body; Described heater is to the air heat in the cavity, by the air after the heating eye is heated the obturator that makes in the tarsal glands again and melts, relaxes or soften.

Described heater comprises heating wire and a control circuit, comprises at least the first critesistor of being located in the cavity in this control circuit, and the air themperature of described critesistor in cavity makes the circuit of heater disconnect when surpassing predetermined temperature; And at least one the second critesistor that is connected with heating wire.Described the second critesistor disconnects when heating wire surpasses predetermined temperature and makes the heating wire stopped heating.

By above description as can be known, the present invention heats the air in the cavity of sealing by heater, melts or softens thereby make eyelid and evenly be warming up to the tarsal glands tamper on every side.The tarsal glands tamper melts or softeningly also has other possible mode, such as possible medicine thawing etc.The thermoplastic mode is Physical, and is easy to operate and safe.Aerial conduction and radiation indirect mode, make eyelid and be heated on every side more even, avoid calandria directly to eyelid heating may cause local temperature too high make eyelid and around uncomfortable phenomenon; By critesistor control temperature, wherein the second critesistor detecting heating wire temperature is guaranteed overheated abnormal phenomena not to occur.The first resistance detecting treatment space temperature is to guarantee to treat space temperature.

When temperature reaches the thawing of tarsal glands tamper or softens, adopt the roll extrusion mode that tamper is extruded.The roll extrusion mode is compared with the mode of scraping, and not only improves the comfort level of eyelid skin, simultaneously because enough spaces are arranged, tamper can be expressed to around the eyelid.The arc cylinder of indent in the middle of squeegee roller two is large, the eyelid of can fitting fully, compression face is large, pressure is even, and the comfort level that the material selection soft material provides it to contact with eyelid skin.

Squeegee roller is installed on by elastic support in the container cavity of roller, and elastic support bottom elastic construction passes to elastic support with power after making location squeegee roller pressurized thereon, makes the certain elastic space of extruding wheel, has the adjust blood pressure effect.Squeegee roller can be pressed into elastic support with suitable dynamics, or it is separated with elastic support, makes things convenient for cleaning and sterilizing.
