Description

TECHNICAL FIELD

[0001] The utility model belongs to ophthalmic medical instrument technical field, and specifically is a protective eyecup for exposed corneal ulcer. BACKGROUND

[0002] Under physiological conditions, the eyelid realizes two key protection functions through regular blinking: first, it drives tear liquid to form a uniformly distributed dynamic tear film on the corneal surface, maintaining the corneal moisture and optical properties; second, it constitutes a physical barrier to resist external pathogenic microorganisms, suspended particles and mechanical damage. When eyelid closure is incomplete due to pathological factors such as facial nerve palsy, eyelid scar contracture or Graves' eye disease, the cornea will lose multiple protection mechanisms and be exposed to a dry environment, triggering a chain of pathological reactions - initially manifested as punctate epithelial shedding, followed by stromal layer infiltration and ulcer formation, ultimately leading to corneal perforation, endophthalmitis, and even irreversible visual impairment such as eyeball atrophy or corneal scar opacity.

[0003] Corneal protection during sleep faces double challenges: on the one hand, physiological blinking reflex is lost, leading to interruption of tear film renewal; on the other hand, the amount of basal tear secretion dominated by parasympathetic nerves is reduced by about 70%. The exposed corneal surface can develop dehydrated epithelial damage within a few hours, becoming a susceptible window for secondary infection. The current clinical corneal protection scheme mainly includes: drug packaging therapy: high-viscosity antibiotic eye ointment combined with eyelid adhesion; mechanical coverage: application of corneal bandage lens; physical closure device: wearing sealed goggles at night.

[0004] Among them, the sealed goggles can significantly reduce the corneal dehydration rate by creating a humid microenvironment. However, traditional goggles are difficult to meet clinical needs due to the following technical defects: hard polymer frames cause pressure-induced corneal damage; standardized sizes are difficult to match individual orbital anatomical structures; displacement and loss during sleep; non-breathable inner lining causes local temperature rise, which in turn promotes pathogen proliferation.

[0005] The above limitations seriously restrict the clinical application and transformation of corneal protection devices, and urgent technical breakthroughs are needed through material engineering innovation and biological microenvironment regulation. UTILITY MODEL CONTENT

[0030] As shown in Figure 1 , in this embodiment, each eyecup is in an elliptical structure, which is more suitable for the shape of the human eye, the connecting part 101 is an elastic part, which can facilitate the patient to adjust to a more comfortable state for wearing, and the hydrogel lining 2 is made of medical grade hydrogel.

[0031] As shown in Figure 1 , 2 , the fixing part 3 is a pasting component, the pasting component is a low-sensitivity adhesive tape, which can be pasted with the skin of the human body, specifically, the low-sensitivity adhesive tape is a pasting structure extending outward, the front end of the low-sensitivity adhesive tape is a semicircular structure, after the patient wears the eyecup, the low-sensitivity adhesive tape can be pasted with the skin on the temporal lobe side, which plays a role in fixing the protective eyecup, and compared with the hanging connection mode, the wearing is more comfortable, the patient will not have obvious foreign body sensation, and the compression is lower.

[0032] As shown in Figure 2As shown, the protective layer is a double-arch structure 103, the inner arch of the double-arch structure 103 has a larger curvature than the outer arch, specifically, the double-arch structure 103 is made of polyurethane elastic material, which reduces the risk of accidental collision on the eyes of the patient.

[0033] As shown in the drawings, Figure 2 As shown, the buffer interlayer is a memory sponge 104, and the inner curvature radius of the memory sponge 104 is 8mm-12mm.

[0034] As shown in the drawings, Figure 3 As shown, the inner side of the sealing ring 102 is embedded with a moisture-sensitive breathable film 4 for maintaining the air permeability, and the outer side of the moisture-sensitive breathable film 4 is also provided with a nanofiber antibacterial layer 5 to block microorganisms from entering, specifically, the nanofiber antibacterial layer is an electrospun fiber.

[0035] The moisture-sensitive breathable film 4 is arranged at the position of the temple lobe side of the eye mask body 1, avoiding the eyelid activity area and avoiding friction between the eyelid and the position, when the humidity or temperature in the eye mask increases, the micropores of the film material automatically expand, increasing the air permeability; when the environment is dry, the micropores shrink, maintaining the sealing property.

[0036] The sealing ring 102 is a medical silicone ring, in other schemes, the sealing ring 102 can also adopt a conformal ring structure of hydrogel and silicone, with the inner side being hydrogel and the outer side being silicone.

[0037] The eye mask body 1 is provided with a positive water replenishing hole, and a silicone duckbill valve is arranged in the water replenishing hole to satisfy the liquid single flow to prevent liquid leakage, and a protective rubber plug is also arranged at the water replenishing hole, when the water content of the internal hydrogel lining 2 is insufficient, the protective rubber plug is opened, and a sterile saline is sucked by a syringe to replenish water for the internal hydrogel lining 2, when replenishing water, the water content can be distributed more uniformly by slight pressing, and the eye mask is worn after standing for 1min.

[0038] The embodiment also provides a manufacturing process of the protective eye mask, first, the hydrogel lining is treated by a pre-crosslinking process, the memory sponge is pre-formed and molded, then the moisture-sensitive breathable film and the nanofiber antibacterial layer are compounded by electrospinning, and the silicone duckbill valve is injection molded by liquid silicone;

[0039] First, the main frame of the protective eye mask is processed and formed, the sealing ring is synchronously processed and formed, then the positive water replenishing hole is processed by numerical control, and the double-arch structure is processed by a vacuum heat pressing compounding process, and the memory sponge is placed in the middle.

[0040] The inner side of the sealing ring is slotted, the moisture-sensitive breathable film is cut and embedded in the slot, the surface of the main frame is cleaned, then the prepolymer of the hydrogel is coated, and then UV curing is performed.

[0041] The main frame and protective layer are fixedly connected by ultrasonic welding. If low-sensitivity adhesive tape is used for fixing, it is cold-pressed; if elastic band is used, it is high-frequency heat-sealed. The duckbill valve is automatically press-fitted.

[0042] Finally, the product undergoes sterilization and is sealed in packaging.

[0043] The protective goggles in this solution feature a design that conforms to the eye socket, making them more comfortable for patients and reducing protruding structures. The biomimetic design improves pressure distribution uniformity, preventing secondary corneal damage caused by localized pressure. A double-arched protective layer is located on the outside of the goggles; the arched structure with different curvatures absorbs most of the impact energy, protecting the patient's eyes. The memory foam 104 prevents sleep-induced pressure ischemia and provides further cushioning. The moisture-sensitive breathable membrane 4 balances moisture and breathability, while also providing antibacterial properties. The fixing part 3 uses hypoallergenic tape or elastic bands for fixation, suitable for different skin conditions. Active hydration holes replenish the hydrogel, ensuring moisture retention. The overall structural design prioritizes lightweight construction and enhanced patient comfort.

[0044] Example 2

[0045] In this embodiment, the fixing part 3 is an elastic band. The user can fix the protective goggles with the elastic band. The two ends of the elastic band are fixedly connected to the two sides of the goggles body 1 respectively. For patients with sensitive skin, the elastic band fixing method can be used.

[0046] Example 3

[0047] In this embodiment, the structure of the protective goggles is basically the same as that of Embodiment 1. The difference is that the active hydration hole is removed, and the medical hydrogel liner 2 adopts a detachable structure, which can be removed for hydration treatment, making it easy to replace the medical hydrogel liner 2. In addition, the medical hydrogel liner 2 is a hydrogel with added sodium alginate, which can absorb sodium ions in tears and expand in a dry environment to release moisture without external intervention, thus prolonging the moisturizing time.

[0048] Example 4

[0049] In this embodiment, as Figure 4 As shown, the eye mask body includes a single eye mask, with a fixing part 3 on each side of the eye mask. The fixing part 3 is made of hypoallergenic adhesive tape for comfortable wear by patients with one eye.
