Abstract
Description
Technical Field
[0001] This utility model relates to the field of ophthalmic medical devices, specifically to a dry eye treatment head and a dry eye treatment instrument. Background Technology
[0002] Traditional dry eye treatment heads have a cup structure that rests against the eyeball, creating a sealed area under negative pressure. This negative pressure often pulls on the eyeball when the treatment head is removed after treatment, posing a risk of damage to the cornea and conjunctiva. Therefore, there is an urgent need for a safer dry eye treatment device that can effectively treat dry eye. Utility Model Content
[0003] In view of the above problems, this utility model provides a dry eye treatment head and a dry eye treatment instrument, which can treat dry eye without harming the eyes.
[0004] In a first aspect, a dry eye treatment head is provided, comprising an eye cup and an air bladder connected to the eye cup. The eye cup includes a receiving cavity with an opening formed by an arcuate sidewall. The arcuate sidewall includes at least an inner sidewall, a heating layer, and an outer sidewall. At least one groove is formed on the inner sidewall. When the inner sidewall abuts against the eyeball, the eyeball and the receiving cavity communicate with the external environment through the groove to form an unsealed air cavity. The heating layer generates therapeutic heat that is transferred to the inner eyelid through the outer sidewall.
[0005] In some embodiments, the size of the opening of the receiving cavity is set such that a portion of the inner wall of the eye cup abuts against the sclera of the eyeball.
[0006] In some embodiments, the grooves include a plurality of grooves that are evenly spaced circumferentially along the inner sidewall and extend from the opening of the receiving cavity to the bottom of the receiving cavity.
[0007] In some embodiments, the outer sidewall is in contact with the heating layer, and there is a gap between the inner sidewall and the heating layer.
[0008] In some embodiments, the eye cup further includes an airbag connector connected to the outer side wall and extending in a direction away from the opening of the receiving cavity. The airbag is movably connected to the eye cup via the airbag connector. The movable connection includes a rotational connection and a telescopic connection.
[0009] In some embodiments, the airbag includes an airbag assembly consisting of a first airbag and a second airbag, the first airbag and the second airbag being movably connected to the eye cup via the airbag connecting portion.
[0010] In some embodiments, the airbag connection portion includes a first pivot bracket and a second pivot bracket, wherein the first pivot bracket is provided with a first pivot hole and a second pivot hole in a direction perpendicular to the airbag connection portion, and the second pivot bracket is provided with a third pivot hole and a fourth pivot hole in a direction perpendicular to the airbag connection portion. The first airbag is rotatably connected to the airbag connection portion through the first pivot hole and the third pivot hole, and the second airbag is rotatably connected to the airbag connection portion through the second pivot hole and the fourth pivot hole.
[0011] In some embodiments, the airbag connection portion includes a first telescopic bracket and a second telescopic bracket, wherein the first airbag is telescopically connected to the airbag connection portion via the first telescopic bracket, and the second airbag is telescopically connected to the airbag connection portion via the second telescopic bracket.
[0012] In some embodiments, a PCB board is inserted into the airbag connection portion, and the PCB board is connected to the heating layer and controls its heating.
[0013] In a second aspect, a dry eye treatment device is provided, including a main unit and a dry eye treatment head as described above, wherein the dry eye treatment head is detachably connected to or wirelessly connected to the main unit.
[0014] In the technical solution of this utility model embodiment, the inner wall of the eye cup abuts against the eyeball, and the heating layer heats the meibomian glands of the upper and lower eyelids. To prevent heat from being transferred from the heating layer to the eyeball, an air cavity is left between the receiving cavity of the treatment head that accommodates the eyeball and the eyeball. The air cavity can prevent the formation of a heat insulation layer between the eye cup with the heating layer and the cornea of the eyeball, protecting the cornea from heat. Furthermore, the air cavity can prevent the eye cup from directly contacting the cornea, protecting the cornea from stress. More importantly, the dry eye treatment head of this utility model, by opening a groove with one end connected to the outside and the other end connected to the air cavity, makes the air cavity a non-sealed air cavity. This retains the advantage of the air cavity protecting the cornea from heat and stress, and also allows for safe removal of the treatment head from the eye after treatment.
[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0033] In the description of the embodiments of this utility model, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).
[0034] As a vital sensory organ, the eyes require careful treatment to address not only the underlying condition but also to prevent further damage during the treatment process. Treatment for dry eye focuses on heating and squeezing the eyelids. This heat and pressure help to expel blockages from the meibomian glands, clearing blockages and relieving dry eye symptoms.
[0035] The dry eye treatment head of this invention includes an eye cup for contacting the eyeball. The eye cup releases heat to the eyelid. To prevent damage to the eyeball from the heat released by the eye cup, this invention leaves an air cavity between the receiving cavity of the eyeball and the eyeball, forming an air isolation between the eyeball and the heat source, especially the air isolation between the eyeball and the cornea, ensuring to a certain extent that the cornea is not exposed to heat or force. More importantly, the dry eye treatment head of this invention, by creating a groove with one end connected to the outside and the other end connected to the air cavity, creates one or more ventilation slots between the air cavity and the outside. These ventilation slots make the air cavity a non-sealed air cavity, thus retaining the advantage of the air cavity 211 protecting the cornea from heat and force, while also ensuring the safe removal of the treatment head from the eye after treatment.
[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, a dry eye treatment head is disclosed, including an eye cup 20. The eye cup 20 includes a receiving cavity with an opening formed by an arcuate sidewall, the receiving cavity being capable of accommodating a portion of the eyeball 10. The arcuate sidewall includes at least an inner sidewall 21, a heating layer 22, and an outer sidewall 23. When treating dry eye with the treatment head, a portion of the inner sidewall 21 of the arcuate sidewall, i.e., the inner sidewall 21 near the upper edge of the opening, abuts against the eyeball 10, particularly against the sclera of the eyeball 10. The cornea of the eyeball extends into the receiving cavity from the opening of the receiving cavity, forming an air cavity 211 between the eyeball 10 and the bottom of the receiving cavity. Furthermore, at least one groove 212 is formed in the portion of the inner sidewall 21 that abuts against the eyeball 10. When the portion of the inner sidewall 21 abuts against the eyeball 10, the groove 212 can connect the external environment with the air cavity 211, so that the air cavity 211 is an unsealed cavity through the groove 212. The external environment refers to the environment outside the eye cup 20. It should be noted that when part of the inner wall 21 abuts against the eyeball 10, neither end of the groove 212 is covered by the eyeball. One end (extended end) of the groove 212 is connected to the air cavity 211, and the other end (open end) of the groove 212 is connected to the external environment.
[0037] Continue to refer to Figure 2 The inner wall that abuts the eyeball 10 mentioned above refers to the inner wall 21 near the opening. The curvature of the inner wall of the receiving cavity is set to be smaller than the curvature of the eyeball 10 that extends into the receiving cavity. When the inner wall 21 abuts the eyeball 10, there is a gap between the bottom of the inner wall 21 and the eyeball 10, which forms an air cavity 211.
[0038] In some embodiments, grooves 212 are spaced apart on the inner wall 21 of the portion abutting the eyeball 10. It should be noted that grooves 212 are not formed in all areas of the inner wall 21 of the portion abutting the eyeball 10. In the portion of the inner wall 21, there are non-grooved areas and one or more grooved areas, so that the inner wall 21 of the portion abutting the eyeball can both abut the eyeball 10 and, through the grooves 212 communicating with the air cavity 211, make the air cavity 211 a non-closed cavity, thus solving the negative pressure problem of the air cavity 211.
[0039] In some embodiments, a plurality of grooves 212 are evenly spaced around a portion of the inner sidewall 21, the grooves 212 extending from the opening of the receiving cavity to the bottom of the receiving cavity. For example... Figure 1 As shown, four grooves 212 are evenly spaced along the axial direction. These grooves 212 extend from the opening of the receiving cavity to the bottom of the receiving cavity. The extension length is only required to ensure that when the eyecup 20 abuts against the eyeball 10, the extension end of the groove 212 can communicate with the air cavity 211 and the opening end of the groove 212 can communicate with the external environment.
[0040] The aforementioned arc-shaped sidewall heating layer 22 is used to generate therapeutic heat. When treating dry eye syndrome with the treatment head, the inner sidewall 21 abuts against the eyeball, and the inner eyelid contacts the outer sidewall 23, with the heat being transferred to the inner eyelid via the outer sidewall 23. In some embodiments, the outer sidewall 23 is in contact with the heating layer 22, and a gap exists between the inner sidewall 21 and the heating layer 22. The heat generated by the heating layer 22 can be transferred to the outer sidewall 23, but when transferred to the inner sidewall 21, it is blocked by the gap between the inner sidewall 21 and the heating layer 22 and the air cavity 211, thus maximally preventing heat transfer to the eyeball 10. In some embodiments, to more effectively block heat transfer to the eyeball 10, the inner sidewall 21 can be further configured as a heat-insulating material, i.e., the inner sidewall 21 serves as both a support layer and a heat-insulating layer for the eyeball 10.
[0041] In some embodiments, the size of the opening of the receiving cavity is set such that any diameter of the receiving cavity opening is larger than any diameter of the cornea, such that a portion of the inner sidewall 21 of the eyecup 20 abuts against the sclera of the eyeball 10, preventing the eyecup 20 from abutting against the cornea. When the receiving cavity opening is perfectly circular, the diameter of the receiving cavity opening is larger than the diameter of any position on the cornea; when the receiving cavity opening is not perfectly circular, the diameter of any position on the receiving cavity opening is larger than the diameter of any position on the cornea.
[0042] In some embodiments, such as Figures 1-3 As shown, the eye cup of the treatment head also includes an airbag connection 24, which is connected to the outer wall 23 of the arcuate sidewall of the eye cup and extends in a direction away from the opening of the receiving cavity. Figures 4-6The dry eye treatment head also includes an airbag assembly 30, which is connected to the airbag connection portion 24. The airbag assembly 30 can be inflated and deflated. When the airbag assembly 30 is inflated, it can press on the outer eyelid, i.e., the heating layer 22 of the eye cup 20, to heat the inner eyelid. The airbag assembly 30 applies pressure (such as continuous pressure, intermittent pressure, etc.) to the surface of the outer eyelid to clear the meibomian gland openings, facilitating the discharge of meibomian gland blockages and other substances from the glands.
[0043] In some embodiments, the airbag assembly 30 includes a first airbag 31 and a second airbag 32, which are rotatable about the airbag connection portion 24 of the eyecup 20, including rotating simultaneously away from the airbag connection portion 24 and simultaneously rotating towards the airbag connection portion 24. The user of the dry eye treatment device can initially position the first airbag 31 and the second airbag 32 both away from the airbag connection portion 24, i.e., with the airbag assembly 30 in the open state. Figure 6 As shown, the eye cup 20 is placed against the sclera of the eyeball 10. Because the airbag assembly 30 is open, the field of vision is clearer and less distorted, making it easier for users of the dry eye treatment device to insert the eye cup 20 into the eyelid without problems such as it not fitting properly or eyelashes getting caught in the eyelid. After the eye cup 20 is inserted into the eyelid, with part of its inner wall 21 against the sclera of the eyeball 10 and its outer wall 23 against the outer eyelid, the airbag assembly 30 is flipped to be close to the airbag connection part 24, i.e., the airbag assembly 30 is in a snap-fit state. In this state, the first airbag 31 can abut against the outer surface of the upper eyelid, and the second airbag 32 can abut against the outer surface of the lower eyelid. Pressure is applied to the eyelid by inflating the airbag assembly 30.
[0044] Furthermore, such as Figure 1 and Figure 6As shown, the airbag assembly 30 is rotatably connected to the airbag as follows: a first pivot bracket 241 and a second pivot bracket 242 are provided on the airbag connecting part 24. The first pivot bracket 241 has a first pivot hole and a second pivot hole in a direction perpendicular to the airbag connecting part 24. The second pivot bracket 242 has a third pivot hole and a fourth pivot hole in a direction perpendicular to the airbag connecting part 24. The first airbag 31 is rotatably connected to the airbag connecting part 24 through the first pivot hole and the third pivot hole. The second airbag 32 is rotatably connected to the airbag connecting part 24 through the second pivot hole and the fourth pivot hole. This allows the first airbag 31 and the second airbag 32 to rotate simultaneously away from the airbag connecting part 24 or simultaneously towards the airbag connecting part 24, or the first airbag 31 and the second airbag 32 to rotate sequentially away from the airbag connecting part 24, or the first airbag 31 and the second airbag 32 to rotate sequentially towards the airbag connecting part 24. The rotational connection of the airbag assembly is achieved by using the rotating bracket of the airbag connector on the eye cup, which makes the connection between the eye cup and the airbag assembly tighter and more conducive to the treatment operation of heating the inner eyelid and squeezing the outer eyelid of this application.
[0045] In another embodiment, the airbag connection portion includes a first telescopic bracket and a second telescopic bracket. The first airbag is telescopically connected to the airbag connection portion via the first telescopic bracket, and the second airbag is telescopically connected to the airbag connection portion via the second telescopic bracket. This allows the first airbag 31 and the second airbag 32 to move simultaneously away from the outer wall 23 or simultaneously towards the outer wall 23, or the first airbag 31 and the second airbag 32 to move sequentially away from the outer wall 23, or the first airbag 31 and the second airbag 32 to move sequentially towards the outer wall 23.
[0046] In some embodiments, a PCB board may be inserted into the airbag connection portion 24. The PCB board is used to control the heating layer 22 of the arc-shaped sidewall. The PCB board may also be connected to the main unit of the dry eye treatment device to control the heating of the heating layer 22 under the control of the main unit of the dry eye treatment device.
[0047] In some embodiments, a dry eye treatment device is disclosed, including a main unit and a dry eye treatment head. The dry eye treatment head is detachably connected to the main unit, and when the dry eye treatment head is connected to the main unit, the main unit and the dry eye treatment head can communicate with each other. After the main unit and the dry eye treatment head are in communication connection, the main unit can control the heating layer 22 of the dry eye treatment head to generate heat and deliver inflatable gas to the airbag assembly 30 under the operation of the user or after receiving a signal from the user to start treatment. In another embodiment, the dry eye treatment head is wirelessly connected to the main unit, for example, via Bluetooth or wireless communication. After the communication connection is established, the main unit can control the heating layer 22 of the dry eye treatment head to generate heat and deliver inflatable gas to the airbag assembly 30 under the operation of the user or after receiving a signal from the user to start treatment.
[0048] The aforementioned dry eye treatment head includes: an eye cup, the eye cup comprising a receiving cavity with an opening formed by an arcuate sidewall, the arcuate sidewall comprising at least an inner sidewall, a heating layer, and an outer sidewall;
[0049] The receiving cavity can accommodate part of the eyeball, and part of the inner sidewall of the arc-shaped sidewall can abut against the eyeball. An air cavity is formed between the eyeball and the receiving cavity. At least one groove is formed in the part of the inner sidewall that abuts against the eyeball. When the part of the inner sidewall abuts against the eyeball, the groove can communicate with the air cavity so that the air cavity is a non-sealed cavity through the groove.
[0050] The heating layer is used to generate therapeutic heat, which is transferred to the inner eyelid via the outer wall.
[0051] The dry eye treatment device in this embodiment rests against the eyeball through the inner wall of the eyecup. The heating layer heats the meibomian glands of the upper and lower eyelids. To prevent heat from being transferred from the heating layer to the eyeball, an air cavity is provided between the receiving cavity of the treatment head and the eyeball. The air cavity prevents the formation of a heat insulation layer between the eyecup with the heating layer and the cornea of the eyeball, protecting the cornea from heat. Furthermore, the air cavity prevents the eyecup from direct contact with the cornea, protecting the cornea from stress. More importantly, the dry eye treatment head of this invention has a groove that connects one end to the external environment and the other end to the air cavity, making the air cavity a non-sealed air cavity. This retains the advantage of the air cavity protecting the cornea from heat and stress, and also allows for safe removal of the treatment head from the eye after treatment.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
