Description

[Technical Field]

[0001] The present invention is in the technical field of contact lens cleaning, and more particularly, to a contact lens cleaning tool. [Background technology]

[0002] Contact lenses include day-wear contact lenses and corrective lenses. Contact lenses are worn for relatively long periods of time each day, resulting in constant contact with tears. Proteins in tears inevitably accumulate on the surface and inside of the lenses, reducing the lens's oxygen permeability and causing dry eyes, photophobia, and watery eyes. Protein accumulation can also promote the growth of bacteria and microorganisms, leading to corneal infections and ulcers, which can seriously harm ocular health.

[0003] The difficulty and complexity of cleaning lenses has been a problem that has troubled clinical laboratory technicians, parents, and contact lens (RGP, OK, scleral) users. The traditional method of cleaning contact lenses is to rub them with your fingers, but many people do so incorrectly, applying uneven pressure to the lenses and using long fingernails, which can lead to cross-contamination of the lenses with bacteria remaining on the fingers or nails, often resulting in scratches and breakage of the lenses or serious wear on the lens surface, which can lead to insufficient cleaning and changes in the optical properties of the lenses.

[0004] Although there are currently devices for cleaning contact lenses in the prior art, the cleaning effect is often insufficient and the lenses are easily damaged. Summary of the Invention [Problem to be solved by the invention]

[0022] Furthermore, for the sake of convenience, only parts related to the related invention are shown in the drawings. Unless there is a conflict, the embodiments and features of the embodiments of the present disclosure may be combined with each other.

[0023] It should be noted that the concepts of "first," "second," etc. mentioned in this disclosure are merely intended to distinguish different devices, modules, or units, and are not intended to limit the order or interdependence of the functions performed by these devices, modules, or units.

[0024] It should be noted that the modifications "one" and "multiple" referred to in this disclosure are exemplary rather than limiting, and should be understood as "one or more" unless the context clearly indicates otherwise, as would be understood by one of ordinary skill in the art.

[0025] The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0026] The present disclosure will be described in detail below by way of examples with reference to the drawings.

[0027] As shown in FIGS. 1 to 4, a contact lens cleaning tool includes a bristle structure and a support 100, the bristle structure is connected to the support 100, and the bristle structure is used to clean a contact lens.

[0028] Specifically, the brush bristle structure includes a plurality of brush bristle portions 201 and connecting portions 202, both of which are made of flexible material, and the connecting portions 202 are connected to the support 100, and the hardness of the brush bristle portions 201 is 40 to 70 degrees, preferably 50 degrees, and the brush bristle portions 201 and the connecting portions 202 are integrally molded, thereby fixing and connecting the brush bristle portions 201 to the connecting portions 202.

[0029] More specifically, the bristles 201 have a long, conical structure, i.e., the cross-sectional area of ​​the end of the bristles 201 closest to the connecting portion 202 is larger than the cross-sectional area of ​​the end of the bristles 201 farthest from the connecting portion 202, thereby improving the connection effect between the bristles 201 and the connecting portion 202. At the same time, the diameter of the end of the bristles 201 that comes into contact with the lens is reduced, allowing more bristles 201 to come into contact with the lens, thereby increasing the pressing force applied to the lens by each bristles 201 and improving the wiping effect of the bristles 201 on the lens. The hardness of the material of the bristles 201 is controlled, so that the required cleaning effect is achieved without damaging the lens.

[0030] The length of the bristles 201 is 5 to 15 mm, and different types of contact lenses are cleaned. For example, when cleaning OK lenses or scleral lenses, the length of the bristles 201 can be adjusted according to the actual lens size, making it suitable for multiple types of contact lenses with different diameters. The diameter of the maximum end of the bristles 201 is 1 to 2.2 mm, and the diameter of the minimum end of the bristles 201 is 0.5 to 1.2 mm. The size of the bristles 201 is adjusted according to the contact lens to be cleaned. When the bristles 201 come into contact with the lens, one end bends, causing the side walls to abut against the lens surface and move relative to the lens, so that the side walls wipe the lens surface and clean the lens. By setting the length of the bristles 201, the contact area between the bristles 201 and the lens is ensured and their movement is prevented from being hindered by the bristles 201 being too long, thereby improving the lens cleaning effect and ensuring the normal and stable operation of the cleaning tool.

[0031] In another preferred embodiment, the cross-sectional area of ​​the end of the bristle portion 201 close to the connecting portion 202 is smaller than the cross-sectional area of ​​the end of the bristle portion 201 far from the connecting portion 202, and the diameter of the end of the bristle portion 201 connecting to the connecting portion 202 is reduced, thereby increasing the oscillation width of the bristles and increasing the contact area of ​​the cleaning end of the bristle portion 201, thereby utilizing a larger oscillation width to effectively remove proteins on the lens.

[0032] Furthermore, a plurality of bristle portions 201 are provided on one connection portion 202, and the bristle portions 201 are evenly arranged on the connection portion 202 along the length direction of the connection portion 202, with the distance between adjacent bristle portions 201 being 2.5 to 4 mm. Preferably, five bristle portions 201 correspond to each cleaning of one lens, so that the entire lens surface can be cleaned or wiped, thereby ensuring that the lens is thoroughly cleaned.

[0033] The support 100 has a cylindrical rod structure with a hollow center, allowing a transmission structure to be connected to the support 100, and the brush bristle structure to rotate synchronously around the central axis of the support 100, driving the support 100 to clean the lenses. The transmission structure may be a conventional transmission method such as motor transmission, cylinder transmission, or electric push rod transmission. The support 100 is made of plastic, preferably medical-grade plastic, and has a length of 30 to 40 mm, preferably 37 mm when cleaning RGP or OK lenses, and preferably 57 mm when cleaning scleral lenses. This reduces the volume of the liquid storage box, further reducing waste of cleaning liquid and lowering the cost per lens cleaning, provided that it can clean one pair of lenses.

[0034] A connecting ring 102 and a rotation prevention protrusion 103 are provided on the inner wall of the support 100, and the connecting ring 102 is used to connect with the transmission structure. The installation of the rotation prevention protrusion 103 allows the support 100 to rotate stably when driven by the transmission structure, thereby avoiding the occurrence of slippage.

[0035] The number of brush bristle structures may be set according to need, and preferably, eight sets of brush bristle sections 201 are installed on the support 100, i.e., eight brush bristle structures are connected to the support 100, and the eight brush bristle structures are evenly arranged circumferentially on the side wall of the support 100, and cooperate with the rotation of the support 100 to wipe and clean the lens multiple times, thereby greatly improving the cleaning effect of the lens.

[0036] Furthermore, the support 100 is provided with a connecting groove 101 corresponding to the connecting portion 202, the cross section of the connecting portion 202 perpendicular to the central axis direction of the support 100 being a T-shaped structure, and the cross section of the connecting groove 101 perpendicular to the central axis direction of the support 100 being a T-shaped structure, and the brush bristle structure is connected to the support 100 by fitting the connecting portion 202 into the connecting groove 101, so that a partially damaged brush bristle structure can be quickly replaced when necessary, and the number of brush bristle portions 201 on the support 100 can also be quickly adjusted when necessary, thereby meeting the needs of cleaning tools in various different usage scenarios.

[0037] In another preferred embodiment, as shown in FIG. 5 , the connecting part 202 has a sleeve-type structure, the cross-sectional diameter of the support 100 is larger than the inner diameter of the sleeve-type connecting part 203, and the connecting part 202 is connected to the support 100 in an exterior manner, thereby making it easier and faster to install the brush bristle structure. By setting the diameter and inner diameter of the support 100 and the connecting part 202, the connecting part 202 is tightly fitted to the support 100, thereby ensuring the connection effect between the support 100 and the connecting part 202. The installation of the sleeve-type connecting part 203 prevents cleaning liquid from entering the connecting groove 101 and creating a blind spot when cleaning the lens with a cleaning tool, thereby further improving hygiene when using the cleaning tool.

[0038] In another preferred embodiment, as shown in FIG. 6, a cavity for accommodating a contact lens is formed in the hollow structure at the center of the support 100, and a brush bristle structure is connected to the inner wall of the support 100. When cleaning the lens, the lens is placed in the support 100 and the support 100 is rotated, so that the brush bristle part 201 comes into contact with the lens to clean it. By directly designing the center of the support 100 as a lens cleaning storage chamber, the volume of the liquid storage box is greatly reduced, the waste of cleaning liquid is minimized, and the cost per lens cleaning is effectively reduced, meeting the daily use needs of customers.

[0039] The above description merely describes some preferred embodiments of the present disclosure and the technical principles applied thereto. As will be understood by those skilled in the art, the scope of the invention related to the embodiments of the present disclosure is not limited to the technical solutions formed by specific combinations of the above technical features, but should also include other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the invention.
