Description

Technical Field

[0001] This utility model relates to the field of nasal strip technology, specifically to an easy-to-remove nasal strip. Background Technology

[0002] When people have a cold, nasal allergies, rhinitis, or upper respiratory tract infection, they often experience nasal congestion, which greatly affects normal breathing. Especially at night, nasal congestion not only affects the rest of others but also affects one's own sleep quality. While medication can relieve nasal congestion, long-term use is very detrimental to health. Therefore, nasal strips are a good alternative.

[0003] Existing nasal strip products generally use strong, breathable medical pressure-sensitive adhesive as a binder to adhere to the nasal wings. However, due to the high degree of adhesion between the nasal wings and the skin, nasal strips are difficult to remove from the nose and can easily cause skin damage. There is an urgent need in the market for a breathable nasal strip that is both highly breathable and easy to remove from the nose without harming the skin. Utility Model Content

[0004] To address the technical problems of existing nasal strips being difficult to remove and easily damaging the skin, this invention provides an easy-to-remove nasal strip, comprising a spunlace nonwoven fabric inner layer, a first PU film layer fixedly connected to one side of the spunlace nonwoven fabric inner layer, a silicone gel layer on the other side of the first PU film layer, and a backing on the other side of the silicone gel layer; a second PU film layer fixedly connected to the other side of the spunlace nonwoven fabric inner layer, with multiple elastic support strips between the second PU film layer and the spunlace nonwoven fabric inner layer, and the side of the second PU film layer away from the spunlace nonwoven fabric inner layer being bonded to the nonwoven fabric outer layer; because silicone gel has a certain degree of adhesion and good biocompatibility, it can achieve close adhesion to the skin, while being easier to remove without damaging the skin during removal.

[0005] As a preferred embodiment of this utility model, a peppermint oil layer is provided on the side of the non-woven fabric outer layer away from the second PU film layer. Peppermint oil has the effects of cooling and relieving summer heat, refreshing the mind, and can alleviate respiratory problems to a certain extent. In order to prevent the peppermint oil from evaporating, it is completely sealed by aluminum foil packaging.

[0006] As a preferred embodiment of this invention, the inner layer of the spunlace nonwoven fabric is fixedly connected to the first PU film layer and / or the second PU film layer by an adhesive. The adhesive is a medical pressure-sensitive adhesive, which has good breathability and will not cause adverse effects on the skin.

[0007] As a preferred embodiment of this utility model, the number of support bars is 1 to 3, and the length-to-width ratio of the support bars is 15:1.

[0008] As a preferred embodiment of this invention, the elasticity of the support strip is less than the viscosity of the silicone gel layer.

[0009] As a preferred embodiment of this invention, the thickness of the peppermint oil layer is 0.001-0.01 mm.

[0010] As a preferred embodiment of this invention, the coating thickness of the adhesive is 0.1-0.3 mm.

[0011] As a preferred embodiment of this invention, the thickness of the silicone gel layer is 0.3-1.0 mm.

[0012] As a preferred embodiment of this utility model, the nasal strip is generally olive-shaped with arc-shaped ends, wherein the width of the ends is wider than that of the middle.

[0013] As a preferred embodiment of this utility model, the nasal strip can be manufactured in several different specifications and models according to actual needs.

[0014] The beneficial effects of this utility model are:

[0015] 1. The part of this invention that adheres to the skin uses a biocompatible silicone gel instead of conventional medical pressure-sensitive adhesive, which achieves a tight bond with the skin and will not damage the skin when it is removed.

[0016] 2. The outermost layer of this invention is coated with peppermint oil, which has the effects of cooling and relieving summer heat and refreshing the mind, and can alleviate respiratory problems to a certain extent. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 2The easily removable nasal strip shown is generally olive-shaped with curved ends, the width of which is wider at both ends than in the middle. It consists of a spunlace nonwoven fabric inner layer 1, with a first PU film layer 2 fixedly connected to one side of the inner layer 1. A silicone gel layer 3 is located on the other side of the first PU film layer 2, and a backing 4 is located on the other side of the silicone gel layer 3. A second PU film layer 7 is fixedly connected to the other side of the inner layer 1. One to three elastic support strips 5 are located between the second PU film layer 7 and the inner layer 1. The side of the second PU film layer 7 away from the inner layer 1 is bonded to the outer nonwoven fabric layer 8. Because silicone gel has a certain degree of adhesion and good biocompatibility, it can achieve a close fit to the skin during use and is easier to remove without damaging the skin.

[0023] In this embodiment, the support strip 5 is located in the middle of the nasal strip and has an aspect ratio of 15:1; the elasticity of the support strip 5 is less than the adhesiveness of the silicone gel layer 3.

[0024] In this embodiment, the inner layer 1 of the spunlace nonwoven fabric is fixedly connected to the first PU film layer 2 and / or the second PU film layer 7 by adhesive 4. The adhesive 4 is a medical pressure-sensitive adhesive with good breathability and will not cause adverse effects on the skin.

[0025] In this embodiment, a peppermint oil layer 9 can also be provided on the side of the nonwoven outer layer 8 away from the second PU film layer 7. Since peppermint oil has the effects of cooling and relieving summer heat and refreshing the mind, it can alleviate respiratory problems to a certain extent. In order to prevent the peppermint oil from evaporating, it is completely sealed by aluminum foil packaging.

[0026] In this embodiment, the thickness of the peppermint oil layer is 0.001-0.01 mm; the coating thickness of the adhesive is 0.1-0.3 mm; and the thickness of the silicone gel layer is 0.3-1.0 mm.

[0027] The nasal strip of this embodiment can be made into different models and specifications according to actual needs.

[0028] Unless otherwise specified in the above description, all parts are prior art or can be implemented using existing technology. Furthermore, the specific embodiments described in this utility model are merely preferred embodiments and are not intended to limit the scope of this utility model. That is, all equivalent changes and modifications made within the scope of this utility model patent should be considered within the technical scope of this utility model.
