TECHNICAL FIELD
[0001] The utility model relates to scleral lens taking off and wearing technical field, concretely relates to a kind of scleral lens taking off and wearing suction stick. BACKGROUND
[0002] In the field of ophthalmology, as a kind of large-diameter rigid gas-permeable contact lens, scleral lens is widely used in the treatment of difficult eye diseases and complex refractive error patients. In the process of taking off and wearing scleral lens, the stability and ease of use of the suction stick as an auxiliary tool are directly related to the wearing experience and comfort of the patient. However, the base of the traditional suction stick is often too simple, such as simple circular or flat design, lacking sufficient support area and anti-slip design, resulting in unstable placement of the suction stick on the desktop or operating table, which causes contamination when the suction stick comes into contact with the desktop. In view of this, the present application is proposed. SUMMARY
[0003] The present application proposes a kind of scleral lens taking off and wearing suction stick to solve the technical problem that the base of the traditional suction stick in the prior art is often too simple, such as simple circular or flat design, lacking sufficient support area and anti-slip design, resulting in unstable placement of the suction stick on the desktop or operating table, which causes contamination when the suction stick comes into contact with the desktop. The above technical purpose of the utility model is realized by the following technical scheme:
[0004] A kind of scleral lens taking off and wearing suction stick, including taking off and wearing department, through-hole, cavity, handheld part, base and limit slot, the top of the taking off and wearing department is concave suction disc, the through-hole is arranged in the center position of the taking off and wearing department, the taking off and wearing department is connected with the handheld part, the cavity is opened in the middle inside the handheld part, the through-hole and the cavity are communicated, the base is equipped with chamber inside, the handheld part and the internal chamber of the base are interference fit, the limit slot is opened in the top peripheral position of the base.
[0005] Further, the base is rectangular.
[0006] Further, the top of the taking off and wearing department is circular in transverse section.
[0007] Further, the taking off and wearing department and the handheld part are integrally formed.
[0008] Further, the surface of the handheld part is uniformly provided with a plurality of convex points.
[0009] Further, the base is provided with a cover.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] This application incorporates a base to ensure the suction cup is securely placed on a desktop or work surface, reducing the risk of slipping and tipping, and improving operational safety.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0018] Please see the appendix Figs. 1-2The sclera lens wearing and taking suction rod comprises a wearing and taking part 1, a through hole 2, a cavity 3, a hand holding part 4, a base 5 and a limiting groove 6, the top of the wearing and taking part 1 is in the shape of a concave suction cup, the top of the wearing and taking part 1 is in the shape of a circle in the transverse section, the through hole 2 is arranged at the center position of the wearing and taking part 1, the wearing and taking part 1 is connected with the hand holding part 4, the cavity 3 is arranged in the middle of the inside of the hand holding part 4, the through hole 2 and the cavity 3 are communicated, the inside of the base 5 is provided with a chamber, the hand holding part 4 and the chamber in the inside of the base 5 are in interference fit, the limiting groove 6 is arranged at the peripheral position of the top of the base 5, and the base 5 is in the shape of a rectangle.
[0019] By adopting the above technical scheme, the concave suction cup-shaped design of the top of the wearing and taking part 1 enables the wearing and taking part 1 to closely fit the edge of the sclera lens, and the sclera lens is firmly adsorbed on the wearing and taking part 1 through the negative pressure principle (i.e. the suction cup effect). The through hole 2 is located at the center of the wearing and taking part 1, and is used for allowing air to flow when the sclera lens is worn or removed, thereby facilitating the adjustment of the adsorption force, and also serving as a channel through which water flows when the sclera lens is cleaned. The cavity 3 in the inside of the hand holding part 4 is communicated with the through hole 2 of the wearing and taking part 1, and when the sclera lens is worn or removed, the user can adjust the adsorption force of the wearing and taking part 1 on the sclera lens by slightly pressing the hand holding part 4 to change the air pressure in the cavity 3. The existence of the cavity 3 also enables the user to more easily separate the sclera lens from the wearing and taking part 1 through slight operation of the fingers, thereby avoiding the direct pulling of the sclera lens and reducing the risk of damage to the sclera lens and the human eye.
[0020] The inside of the base 5 is provided with a chamber, and the hand holding part 4 is in interference fit with the chamber in the inside of the base 5. This design enhances the connection stability between the hand holding part 4 and the base 5, thereby preventing the hand holding part 4 from falling off during use. The limiting groove 6 is arranged at the peripheral position of the top of the base 5, and the limiting groove 6 is matched with a cover 7. By arranging the cover 7, the wearing and taking part 1 can be protected from being contaminated.
[0021] The base 5 is in the shape of a rectangle, which makes the base 5 more stable when placed and less likely to roll. Meanwhile, the four right angles of the rectangle can serve as reference points to help the user place the tool more accurately, thereby ensuring that the adsorption part does not directly contact the desktop and reducing the risk of contamination.
[0022] The top of the wearing and taking part 1 is in the shape of a circle in the transverse section, which enables the wearing and taking part 1 to provide more uniform pressure distribution when adsorbing the sclera lens, thereby reducing the damage to the sclera lens caused by excessive local pressure. Meanwhile, the circle is more likely to fit the edge of the sclera lens, thereby improving the stability of adsorption.
[0023] In some embodiments, the wearing and taking part 1 and the hand holding part 4 are integrally formed. The integrally formed design enhances the structural strength between the wearing and taking part 1 and the hand holding part 4, thereby avoiding the weakening of the adsorption force or the falling off of the wearing and taking part 1 due to loose connection.
[0024] In some embodiments, the handheld part 4 is uniformly provided with a plurality of convex points on the surface, the convex points are designed to increase the roughness of the surface of the handheld part 4, improve the friction when the user holds, and effectively prevent the tool from falling off or misoperation due to hand slip.
[0025] In some embodiments, the base 5 is provided with a cover 7.
[0026] With the above technical scheme, the design of the cover 7 can further protect the cavity inside the base 5 from external pollution, especially when not in use, the entire tool can be closed to reduce the chance of bacteria or virus entering, at the same time, the cover 7 can also be used as a small storage tool, which is convenient for the user to carry and store the sclera lens wearing tool.
[0027] It should be understood that the above specific embodiments of the utility model are only used for illustrative or explanatory purposes of the principle of the utility model, and do not constitute a limitation on the utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without deviating from the spirit and scope of the utility model shall be included in the protection scope of the utility model.
