Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an adjustable protective goggles for radiotherapy. Background Technology

[0002] Patients undergoing radiotherapy in hospitals receive high doses of radiation. During treatment, the patient's normal organs and tissues need to be protected from radiation to prevent damage. In radiotherapy for tumors near the eye, studies have confirmed that the maximum tolerated radiation dose for the lens is 9 Gy, and the maximum tolerated radiation dose for the eyeball is 50 Gy. If radiation protection is inadequate during radiotherapy, exceeding these doses can directly lead to irreversible damage to the lens and eyeball, causing blindness and serious complications. Therefore, eye protection during radiotherapy is extremely important.

[0003] Furthermore, the application document with publication number CN214967630U mentions a radiation-proof goggle for radiotherapy. Before wearing the goggle, the patient should open the radiation-proof lens, then place the goggle body in front of the eyeballs, allowing the patient to see objects through the observation hole. The patient can then adjust the adjustable lens to select a suitable refractive power, ensuring the lens covers the observation hole directly. Finally, the first and second restraint straps are secured to the patient's head. At this point, the patient can clearly observe the outside world through the goggle body and the adjustable lens. When the radiation machine emits radiation, rotating the radiation-proof lens further protects the eye. The radiation-proof lens is attached to the adjustable lens and protects the eyeball behind the observation hole, preventing radiation from passing through the adjustable lens and observation hole and causing damage to the eye's vision. During treatment, only the radiation-proof lens needs to be flipped to adjust the treatment posture and during the treatment process, reducing the traditional actions of removing and putting on glasses and greatly improving the efficiency of radiation therapy. However, there are still some defects that need to be optimized. The specific defects are as follows: When using this eye mask, there is no positioning structure between the radiation-proof lens and the eye mask body. It only relies on the hinge structure to rotate, and the eye mask body is easy to flip. At the same time, the restraint strap cannot be finely adjusted, which reduces its practicality.

[0004] Therefore, it is particularly important to design an adjustable protective goggle for radiotherapy to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0009] As a preferred embodiment of this utility model, the lens assembly includes a circular base plate, a plurality of lenses, and a hinge hole. The hinge hole is adapted to the rotating shaft. The plurality of lenses have different refractive powers, and the size of the lenses is adapted to the through hole. Four sets of rotating grooves are equally spaced on the circular base plate.

[0010] As a preferred embodiment of this utility model, the fixing block is provided with a limiting groove for matching the limiting protrusion, and the limiting protrusion and the fixing block are engaged and connected.

[0011] As a preferred embodiment of this utility model, the two sides of the eye mask base plate are symmetrically provided with hinge seats, and the radiation protection sheet and the eye mask base plate can rotate.

[0012] As a preferred embodiment of this utility model, the limiting band is provided with a plurality of hanging holes for matching with the hook, and the other end of the limiting band is connected to the friction anti-rotation baffle.

[0013] As a preferred embodiment of this utility model, the elastic band passes through the fixing plate, the extrusion block is adapted to the limiting groove, the mounting bracket is disposed on the inner side wall of the adjusting cylinder, and one end of the pull rod passes through the adjusting cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, an adjustable radiotherapy protective goggle is designed. Utilizing a structure of a fixing block, a limiting block, a slot, a limiting protrusion, and an adjusting cylinder, it adapts to patients with different myopia conditions by setting lenses of different refractive powers. Simultaneously, the anti-radiation lens can be flipped, and after flipping, its position is fixed by the engagement between the limiting protrusion and the limiting groove. The adjusting cylinder controls the tension of the elastic band, making it easy to adapt to different patients' conditions. This solves the problem that when using this goggle, there is no positioning structure between the anti-radiation lens and the goggle body; it relies solely on a hinge structure for rotation, making the goggle body prone to flipping, and the restraint strap cannot be fine-tuned, resulting in limited practicality.

Subsequently, the position of the lens assembly 103 is fixed by the friction anti-rotation plate 104 to prevent rotation during use. Then, as needed, the user can flip the anti-radiation plate 106 and fix it to the eye mask base plate 1 using the engaging connection between the limiting protrusion and the fixing block 105, providing additional radiation protection to the eyes. For protection, the elastic band 302 is connected to the goggle base plate 1 via the limiting hook 301.

[0027] The working process of this utility model is as follows: When using this adjustable radiotherapy protective goggle, the user first rotates the lens assembly according to their myopia degree via the pivot on the goggle base plate 1 to select a suitable lens to cover the through hole 101, ensuring clear vision. Then, the position of the lens assembly 103 is fixed by the friction anti-rotation plate 104 to prevent rotation during use. Next, as needed, the user can flip the radiation shield 106 and fix it to the goggle base plate 1 using the engaging connection between the limiting protrusion and the fixing block 105, providing additional protection for the eyes. For radiation protection, the elastic band 302 is connected to the goggle base plate 1 via the limiting hook 301.
