Description

Technical Field

[0001] This utility model relates to the field of eye patch technology, and more specifically to a disposable protective eye patch for assisting eyelid closure. Background Technology

[0002] There are many factors that can cause incomplete eyelid closure, including physiological factors, facial nerve paralysis, and scarring of the face with ectropion. Long-term incomplete eyelid closure can cause dryness in the eyes, and patients may feel discomfort in their eyes. In addition, because part of the eyeball is exposed, it is easily affected by external stimuli and infection, which can lead to eye inflammations such as conjunctivitis and keratitis.

[0003] Therefore, for this symptom of incomplete eyelid closure, eye mask products dominate the existing technology, but these products are mainly for patients with long-term incomplete eyelid closure caused by various neurological factors. However, these products are not suitable for individuals who only experience incomplete eyelid closure during sleep. Eye patch products (such as the disposable protective eye patch for incomplete eyelid closure during sleep proposed in Chinese Patent Publication No. CN208598595U) are mostly one-piece designs. This design may have limitations in practical applications, such as not being suitable for patients with different eyelid sizes or being difficult to adapt to different sleeping positions. Moreover, one-piece eye patches often cover the entire eyelash area, resulting in poor breathability and lack of comfort. Utility Model Content

[0004] To address the technical problems existing in current eye patches that assist in eyelid closure, this utility model proposes a disposable protective eye patch for assisting eyelid closure. The protective eye patch is constructed in a strip shape along its thickness direction, and includes:

[0007] A release paper layer, which is bonded to the adhesive layer and can be peeled off from the adhesive layer;

[0008] Wherein, when the release paper layer is peeled off from the adhesive layer, the adhesive layer forms a contact area on one side of the release paper layer and adhesive areas on both sides of the contact area. The contact area corresponds to the position of the intermediate layer. The direction of the line connecting the two adhesive areas is defined as the first direction, and the second direction is perpendicular to the first direction.

[0009] The contact area is set such that its length along the first direction is greater than or equal to its length along the second direction, and the adhesive area is set such that its length along the first direction is greater than or equal to its length along the second direction. The two adhesive areas are attached to the upper and lower eyelids at an angle of 40 to 50 degrees parallel to or inclined to the eye height, and the contact area covers the slit of the eye.

[0010] Preferably, the length-to-width ratio of the protective eye patch is greater than or equal to 3:1.

[0011] Preferably, the width of the protective eye patch is 8-12 mm.

[0012] Preferably, the length of the contact area is greater than or equal to the length of the adhesive area.

[0027] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0028] Combination Figure 1 As shown, this utility model proposes a disposable protective eye patch for assisting eyelid closure. The protective eye patch is constructed in the form of a strip. Along the thickness direction, the protective eye patch includes an adhesive layer 10, an intermediate layer 20, and a release paper layer 30.

[0029] The area of ​​the intermediate layer 20 is smaller than that of the adhesive layer 10. The intermediate layer 20 is connected to a predetermined area of ​​the adhesive layer 10. The release paper layer 30 is bonded to other areas of the adhesive layer 10 other than the intermediate layer 20 and can be peeled off from the adhesive layer 10.

[0030] The purpose of the release paper layer 30 is to protect the bonding area of ​​the adhesive layer 10 from dust contamination and loss of adhesion.

[0031] The adhesive layer 10 includes a base layer 11 and an adhesive layer 12. The base layer 11 includes a polyurethane film, and the adhesive layer 12 includes a medical pressure-sensitive adhesive.

[0032] Combination Figure 2 As shown, before using the protective eye patch, the release paper layer 30 needs to be peeled off to expose the bonding area.

[0033] Combination Figure 3 As shown, when the release paper layer 30 is peeled off from the adhesive layer 10, the adhesive layer 10 forms a contact area 101 on one side of the release paper layer 30 and adhesive areas 102 on both sides of the contact area 101.

[0034] The contact area 101 corresponds to the position of the intermediate layer 20. That is, the intermediate layer 20 covers part of the adhesive area 102 of the adhesive layer 10 to form the contact area 101. The contact area 101 is used to contact the patient's eyelid slit and surrounding area, which can achieve the characteristics of not sticking to the eyelashes and being soft and breathable.

[0035] In an optional embodiment, the length-to-width ratio of the protective eye patch is greater than or equal to 3:1. Thus, the protective eye patch is designed as a narrow strip, making it more flexible to use. Especially when applied to the eyelids, the adhesive areas 102 at both ends can adhere to the eyelid skin tissue, and the tension of the adhesive areas 102 achieves eyelid closure. Even if the face deforms during sleep, the protective eye patch is less likely to deform and lose its protective function of closing the eyelids.

[0036] In a preferred embodiment, the width of the protective eye patch is 8-12 mm and the length is 30-36 mm.

[0037] The length of the contact area 101 is greater than or equal to the length of the adhesive area 102. This allows the contact area 101 to maintain a larger contact area with the eye slit. Preferably, the size of the contact area 101 is 10mm*10mm, that is, both the length and width are 10mm.

[0038] In an optional embodiment, the intermediate layer 20 includes a non-woven light-shielding layer. Preferably, the non-woven light-shielding layer comprises a single layer of black PE non-woven fabric. The thickness of the intermediate layer 20 is 0.125 ± 0.05 mm. This thinner design reduces discomfort.

[0039] Thus, the contact area 101 is non-adhesive, which protects the eyelids, eyelashes and other tissues from damage, and also provides a certain degree of light-blocking effect.

[0040] Combination Figure 4 As shown, the adhesive area 102 located on the contact area 101 adheres to the upper eyelid at a distance of 15 mm, and the adhesive area 102 located below the contact area 101 adheres to the lower eyelid at a distance of 15 mm. Through the pulling action of the adhesive layer 10, the eyelid is completely closed, and the contact area 101 covers the eye slit.

[0041] The direction of the line connecting the two adhesive regions 102 is defined as the first direction, and the second direction is perpendicular to the first direction. The contact region 101 is set to have a length along the first direction that is greater than or equal to the length along the second direction, and the adhesive region 102 is set to have a length along the first direction that is greater than or equal to the length along the second direction.

[0042] As can be seen, the contact area 101 is set to a square or long rectangular shape, and the eye patch is strip-shaped as a whole, which can adapt to people of different ages and eye sizes, with high flexibility and good comfort.

[0043] Optionally, the two adhesive areas 102 are attached to the upper and lower eyelids at an angle of 40-50° parallel to or inclined to the eye level, and the contact area 101 covers the slit of the eye.

[0044] Combination Figure 5 As shown, if the user is a child or a user with small eyes, a single protective eye patch can be used. Specifically, the two adhesive areas 102 are applied to the upper and lower eyelids along a direction parallel to the eye height, and the contact area 101 covers the slit of the eye.

[0045] Combination Figure 6 As shown, if the user has large eyes, two protective eye patches should be applied crosswise. Specifically, the two adhesive areas 102 of the first eye patch should be applied at a 40-50° angle to the eye height on the upper and lower eyelids, with the contact area 101 covering the slit of the eye. Then, the two adhesive areas 102 of the second eye patch should be applied crosswise with the first eye patch, so that the two eye patches form a cross shape, ensuring that the patient's eyelids can be fully closed during sleep.

[0046] Based on the above embodiments, the eye patch proposed in this utility model is strip-shaped, including a contact area in the middle and adhesive areas on both sides of the contact area. The two adhesive areas can be adhered to the upper and lower eyelids respectively. Compared with the current one-piece eye patch, the disposable eye patch proposed in this application can flexibly adapt to different eyelid sizes of different people, with appropriate overall coverage of the eyelash area, good breathability, good comfort, strong adhesion, and is not easy to deform and fall off due to different sleeping positions, thus meeting clinical needs. The eye patch is easy to operate and inexpensive.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
