Description
Technical Field
[0001] The invention relates to the technical field of medical protective equipment, and in particular to a pair of medical goggles with replaceable lenses. Background Art
[0002] Medical goggles, also known as protective glasses and eye masks, can prevent medicine, blood, aerosol droplets, etc. from splashing into the eyes, thereby isolating and protecting the eyes. They are usually used in conjunction with masks and protective clothing (or surgical caps, etc.) to provide comprehensive protection for the user's entire head; they are especially suitable for use during epidemics of respiratory infectious diseases, such as the new coronavirus epidemic.
[0003] In recent years, the incidence of myopia in my country has reached 33%, which is 1.5 times the world average, and shows an increasing trend year by year. However, existing medical goggles are not suitable for myopic people. On the one hand, the lenses in existing medical goggles are clear lenses, which cannot effectively correct the wearer's vision, so that myopic people have problems seeing clearly after wearing medical goggles, which has a great impact on the wearer, especially for medical staff, which will seriously affect their work. On the other hand, if myopic glasses are worn in medical goggles, it is not only inconvenient to wear medical goggles, but also causes a gap between the medical goggles and the wearer's skin, which fails to achieve the purpose of isolating and protecting the eyes, and there is a risk of infection. Therefore, it is urgent to develop medical goggles suitable for myopic people, especially myopic medical staff. Summary of the invention
[0004] The purpose of the present invention is to improve the deficiencies of the prior art and provide a medical goggles with a simple and compact structure, which can not only conveniently replace the lenses to meet the needs of different wearers, especially meet the needs of the majority of myopic medical staff, but also have strong versatility and low cost, which is conducive to wide promotion and use, and is particularly suitable for epidemics of respiratory infectious diseases.
[0005] The technical solution adopted by the present invention is:
[0006] A kind of medical goggles with replaceable lenses, comprising a frame for covering the wearer's eyes and a lens for seeing objects, wherein the lens is detachably mounted on the frame, and the edge of the lens forms a seal with the frame. The medical goggles provided by this scheme have lenses detachably mounted on the frame so as to separate the lenses and the frame, so that during use, the wearer can match the corresponding lenses according to their actual needs, such as whether they have myopia, the degree of myopia, etc., and conveniently install them on the frame; and after the lenses are installed, the edges of the lenses can form a good seal with the frame, which is conducive to better isolation and protection of the wearer's eyes.
[0007] Preferably, the frame is provided with two mounting holes for mounting lenses, the two mounting holes are round holes, and the lenses are round lenses that match the mounting holes. Because in the prior art, the lenses used for glasses are usually round after leaving the factory, which are called original lenses. Usually, only before being mounted on the frame, the edges of the original lenses are polished according to the needs of the purchaser and formed into a shape that matches the frame. In this solution, the mounting holes are set as round holes to match the round lenses, so that the medical goggles can directly use the existing original lenses, which not only eliminates the polishing process and greatly reduces the cost, but also makes the frame more versatile and can be applied to round lenses of different degrees to meet the needs of different wearers.
[0008] Preferably, the lens is a concave lens or a plano lens. When the lens is a concave lens, it can correct the wearer's vision, and different concave lenses can be selected according to the wearer's degree, so that it is suitable for myopic people to wear. When the lens is a plano lens, it has no refractive power and cannot correct myopia, so it is suitable for non-myopic people to wear.
[0009] In order to realize the detachable installation of the lens in the medical goggles, preferably, the installation hole is provided with an annular sealing ring, and the inner side surface of the annular sealing ring is provided with a first annular groove, and the first annular groove is used to clamp the edge of the lens. That is, the lens can be installed in the first annular groove, and the edge of the lens is wrapped by the first annular groove, which can not only fix the lens, but also achieve a good sealing effect to prevent the glasses from being infected.
[0010] In order to securely fix the lens and prevent it from falling off from the inside of the frame during use, preferably, the mounting hole is a stepped hole, and the annular sealing ring is arranged at the step of the stepped hole; or, an annular retaining ring is arranged in the mounting hole, and the annular sealing ring is arranged on the outside of the annular retaining ring. The step of the stepped hole or the annular retaining ring can effectively block one side of the annular sealing ring and provide support force for one side of the annular sealing ring, thereby effectively preventing the lens from falling off from the inside of the frame, which is conducive to improving stability.
[0011] In order to simplify the structure, reduce costs, and facilitate the installation and fixation of the annular sealing ring, further, the outer side of the annular sealing ring is provided with a second annular groove, and the second annular groove is adapted to the edge of the mounting hole and is used to clamp the edge of the mounting hole. In this solution, the edge of the mounting hole is clamped by the second annular groove, so that the annular sealing ring can be stably installed on the frame. In this way, further processing and shaping of the mounting hole can be avoided, so that the structure of the mounting hole is as simple as possible, thereby effectively reducing costs.
[0012] In order to make the connection between the annular sealing ring and the frame more secure, a circle of annular protrusions is further provided along the circumferential direction of the mounting hole, the second annular groove is adapted to the annular protrusions, and the frame clamps the annular sealing ring through the annular protrusions. This can not only realize the installation and fixation of the annular sealing ring, but also facilitate the replacement of the annular sealing ring, and also make it easier to install the lens.
[0013] Preferably, the annular protrusion is a circular ring. The use of an annular protrusion in the shape of a circular ring is conducive to increasing the contact area between the annular protrusion and the second annular groove, improving the stability of the connection, and making the annular sealing ring and the frame form a flexible connection, with a certain degree of freedom between the two, so that the lens is not easy to fall off or damage.
[0014] In order to prevent the wearer from being locally crushed by the medical goggles, especially by wearing the medical goggles for a long time, a circle of flexible suction cups is further provided along the edge of the frame, and the flexible suction cups are used to contact the wearer's skin. By providing the flexible suction cups, on the one hand, the contact area between the frame and the wearer's face can be effectively increased, and the pressure can be reduced, thereby effectively alleviating or avoiding local crushing injuries. On the other hand, flexible contact can be achieved, and the comfort of the wearer can be improved. In addition, the suction cups can also achieve a better sealing effect and enhance the effectiveness of isolation and protection.
[0015] In order to facilitate the stably wearing of the medical goggles on the head, the medical goggles further include a restraint belt, the two ends of which are respectively connected to the two sides of the frame and form a ring structure with the frame, so as to facilitate wearing.
[0016] Preferably, the restraint belt is an elastic belt or is provided with a section of elastic belt, so as to be suitable for people with different head sizes.
[0017] Compared with the prior art, the medical goggles with replaceable lenses provided by the present invention have the following beneficial effects:
[0018] 1. This medical goggles has a simple and compact structure. It can not only easily replace the lenses to meet the needs of different wearers, but also meet the needs of myopic medical staff. It is especially suitable for use during epidemics of respiratory infectious diseases.
[0019] 2. The medical goggles are low in cost, simple in lens installation and replacement, highly versatile, and conducive to wide promotion and use.
[0020] 3. The medical goggles can not only effectively increase the contact area between the frame and the wearer's face and reduce the pressure, thereby effectively alleviating or avoiding local compression injuries, but also achieve flexible contact and improve the wearer's comfort. In addition, the suction cup can also achieve a better sealing effect and enhance the effectiveness of isolation and protection. BRIEF DESCRIPTION OF THE DRAWINGS

The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.
[0033] Example 1
[0034] See also Figure 1-Figure 4 In this embodiment, a medical goggles with replaceable lenses is provided, comprising a frame 100 for covering the wearer's eyes and a lens 200 for seeing objects, wherein the lens 200 is detachably mounted on the frame 100, and the edge of the lens 200 forms a seal with the frame 100. In this embodiment, the lens 200 is detachably mounted on the frame 100 so as to separate the lens 200 and the frame 100, so that during use, the wearer can match the corresponding lens 200 according to his actual needs, such as whether he has myopia, the degree of myopia, etc., and conveniently install it on the frame 100; and after the lens 200 is installed, the edge of the lens 200 can form a good seal with the frame 100, thereby facilitating a better isolation and protection effect on the wearer's eyes.
[0035] It can be understood that in this embodiment, the frame 100 can be made of materials commonly used in the prior art. In order to reduce costs, it can usually be made of plastic, polymer materials, etc., which will not be described here.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate the medical goggles to be stably worn on the head, a restraint belt 400 is also included, and the two ends of the restraint belt 400 are respectively connected to the two sides of the frame 100, and form a ring structure with the frame 100. This makes it easier to wear; preferably, the restraint belt 400 can be an elastic belt or be provided with at least one section of elastic belt, so that the restraint belt 400 has a telescopic function, so as to be suitable for people with different head sizes.
[0037] In order to prevent the restraint belt 400 from exerting continuous pressure on the ears and causing ear discomfort when the wearer wears the medical goggles for a long time, in a preferred embodiment, one end of the restraint belt 400 connected to the frame is a Y-shaped structure or a V-shaped structure so as to bypass the wearer's ears and avoid oppression on the ears, thereby making it easier to wear the medical goggles for a long time.
[0038] like Figure 1-Figure 3As shown, in this embodiment, the frame 100 is provided with two mounting holes 101 for mounting the lenses 200, the two mounting holes 101 are round holes, and the lenses 200 are circular lenses 200 that match the mounting holes 101. In the prior art, the lenses 200 used for glasses are usually round after leaving the factory, which are called original lenses 200. Usually, only before being mounted on the frame 100, the edges of the original lenses 200 are polished according to the needs of the purchaser and formed into a shape that matches the frame 100. In this solution, in order to provide versatility, the mounting holes 101 are set as round holes to match the circular lenses 200, so that the medical goggles can directly use the existing original lenses 200, which not only eliminates the polishing process and greatly reduces the cost, but also makes the frame 100 more versatile and can be applied to circular lenses 200 of different degrees to meet the needs of different wearers.
[0039] In this embodiment, the lens 200 can be a concave lens or a plano lens. When the lens 200 adopts a concave lens, it can correct the wearer's vision, and different concave lenses can be selected according to the wearer's degree, so that it is suitable for myopic people to wear. When the lens 200 adopts a plano lens, it has no refractive power and cannot correct myopia, so it is suitable for non-myopic people to wear. Therefore, the medical goggles can be worn by everyone and have strong versatility.
[0040] In order to realize the detachable installation of the lens 200 in the medical goggles, in a preferred solution, the mounting hole 101 is provided with an annular sealing ring 300, and the inner side of the annular sealing ring 300 is provided with a first annular groove 301, and the first annular groove 301 is used to clamp the edge of the lens 200. Figure 2 and Figure 3 That is, the lens 200 can be installed in the first annular groove 301, and the edge of the lens 200 is wrapped by the first annular groove 301, which can not only fix the lens 200, but also achieve a good sealing effect to prevent the glasses from being infected.
[0041] In order to firmly fix the lens 200 and prevent the lens 200 from falling off from the inside of the frame 100 during use, in a preferred implementation manner provided in this embodiment, the mounting hole 101 shown can be a stepped hole, and the annular sealing ring 300 is arranged at the step of the stepped hole; in another implementation manner, an annular retaining ring 102 is arranged in the mounting hole 101, and the annular sealing ring 300 is arranged on the outside of the annular retaining ring 102, such as Figure 4The step of the stepped hole or the annular retaining ring 102 can effectively block one side of the annular sealing ring 300 and provide support for one side of the annular sealing ring 300, thereby effectively preventing the lens 200 from falling off from the inside of the frame 100, which is conducive to improving stability.
[0042] It can be understood that in this embodiment, the annular sealing ring 300 can be made of rubber or polymer material. In this embodiment, the annular sealing ring 300 can be made of transparent plastic, which will not be described here.
[0043] In a more optimized solution, in order to solve the problem that the lens 200 is prone to fogging, in this embodiment, one side or both sides of the lens 200 can be coated. The coating can effectively solve the problem of fogging of the lens 200, and the coating can be achieved using the coating process and coating materials commonly used in the prior art, which will not be explained one by one here.
[0044] When the medical goggles are actually used, after the user has selected the lens 200 suitable for his or her eye power, the user can insert the lens 200 into the annular sealing ring 300 by physically pressing, thereby seamlessly connecting the lens 200 with the frame 100 as a whole.
[0045] Example 2
[0046] In order to simplify the structure, reduce the cost, and facilitate the installation and fixation of the annular sealing ring 300, the main difference between the present embodiment 2 and the above-mentioned embodiment 1 is that in the medical goggles provided in the present embodiment, the outer side surface of the annular sealing ring 300 is provided with a second annular groove 302, and the second annular groove 302 is adapted to the edge of the mounting hole 101 and is used to clamp the edge of the mounting hole 101. Figure 5 As shown, the second annular groove 302 is used to clamp the edge of the mounting hole 101, so that the annular sealing ring 300 can be stably installed on the frame 100. In this way, further processing and shaping of the mounting hole 101 can be avoided, so that the structure of the mounting hole 101 can be as simple as possible, thereby effectively reducing costs.
[0047] In order to make the connection between the annular sealing ring 300 and the frame 100 more secure, in a further solution, a circle of annular protrusions 103 are provided along the circumferential direction of the mounting hole 101, the second annular groove 302 is adapted to the annular protrusions 103, and the frame 100 clamps the annular sealing ring 300 through the annular protrusions 103. This can not only realize the installation and fixation of the annular sealing ring 300, but also facilitate the replacement of the annular sealing ring 300. In addition, it is also more convenient to install the lens 200; as an example, Figure 5As shown, the annular protrusion 103 is a circular ring, and the diameter of the cross section of the circular ring is larger than the thickness of the lens frame 100 at the mounting hole 101. Figure 5 As shown, the use of the annular protrusion 103 in a circular ring shape can make the annular sealing ring 300 and the annular protrusion 103 form a ball-hinged effect, which is beneficial to increase the contact area between the annular protrusion 103 and the second annular groove 302 and improve the stability of the connection, and the annular sealing ring 300 and the frame 100 can form a flexible connection, so that there is a certain degree of freedom between the two, and the lens 200 is not easy to fall off or be damaged.
[0048] Example 3
[0049] In order to prevent the wearer from being locally injured by the medical goggles, especially by wearing the medical goggles for a long time, the difference between the present embodiment 3 and the above-mentioned embodiment 1 or embodiment 2 is that in the medical goggles provided in the present embodiment, a circle of flexible suction cups 104 is provided along the edge of the frame 100, and the flexible suction cups 104 are used to contact the wearer's skin. As an example, Figure 1-Figure 5 As shown, the flexible suction cup 104 is perpendicular to the frame 100. By providing the flexible suction cup 104, on the one hand, the contact area between the frame 100 and the wearer's face can be effectively increased and the pressure can be reduced, thereby effectively alleviating or avoiding local compression injuries. On the other hand, flexible contact can be achieved to improve the wearer's comfort. In addition, the suction cup can also achieve a better sealing effect and enhance the isolation and protection effect.
[0050] Preferably, the flexible suction cup 104 may be made of soft rubber or silicone, and the flexible suction cup 104 may have a certain curvature to improve the adsorption performance. In the actual production and manufacturing process, the width of the flexible suction cup 104 may be determined according to actual needs, and may usually be greater than the thickness of the frame 100. Examples will not be given here one by one.
[0051] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
