Dressing patch product packaging structure

Abstract

A dressing patch product packaging structure, comprising a first packaging layer (1), a second packaging layer (2), and a dressing patch product (3). The dressing patch product (3) comprises a base layer (301) and an adhesive layer (302) applied on the base layer (301). A packaging space is formed between the first packaging layer (1) and the second packaging layer (2) by means of an edge sealing portion (4), and the dressing patch product (3) is packaged in the packaging space. The side of the first packaging layer (1) that faces the packaging space is coated with a first release agent layer (5); the adhesive layer (302) of the dressing patch product (3) is directly adhered to the first release agent layer (5), and a coating area of the first release agent layer (5) is greater than or equal to a projection area of the adhesive layer (302). The packaging structure solves the technical problems associated with packaging using release paper and / or release film, i.e., the adhesion between the packaging materials and the product, the generation of substantial medical waste, and the inability to directly observe surface contamination on the product, thereby facilitating the separation between the dressing patch product packaging structure and the adhesive product.

Description

Dressing patch product packaging structure Technical Field

[0001] This invention relates to the field of product packaging technology, and in particular to a packaging structure for dressing patches. Background Technology

[0002] Sheet-shaped products with one side coated with adhesive, including but not limited to bandages, dressings, or medical patches; in the prior art, to avoid the adhesive from sticking to the packaging material and making the product impossible to peel off, release paper and / or release film are used to cover the entire adhesive area for packaging.

[0003] However, in practical applications, due to the adhesive nature of the hydrocolloid matrix, even when the matrix is ​​completely covered by release paper, the edges of hydrocolloid dressings can still overflow, causing adhesion to the packaging material. To avoid this adhesion, existing packaging often uses two release papers and / or release films with an area larger than the product to hold it in place. However, since there is no connection between the product and the two release papers and / or release films, displacement can occur during transportation and storage, still resulting in adhesion to the packaging and poor anti-adhesion effect. Furthermore, a large amount of release paper used in ordinary sterile dressings or other dressing products needs to be discarded after use, leading to cost waste and generating significant medical waste. Moreover, due to the extremely poor transparency of release paper, it is impossible to directly observe whether the adhesive surface of the product and the core area surrounded by the adhesive surface have been contaminated during production, potentially leading to contaminated or substandard products entering the market and causing medical accidents.

[0004] Based on the above analysis, the problems and defects of existing dressing and patch products using release paper and / or release film in their packaging structure are as follows:

[0005] (1) Material overflow at the edges may cause the product to stick to the packaging material;

[0006] (2) After using a large amount of release paper, it needs to be discarded, which not only wastes costs but also generates a large amount of medical waste;

[0007] (3) The release paper has extremely poor transparency, making it impossible to directly observe whether the product surface is contaminated;

[0008] (4) The release paper provided in the prior art is inconvenient for medical staff to operate when dealing with long, irregularly shaped and open-hole dressings.

[0009] (5) The existing packaging body, the dressing and packaging materials are completely separate, which results in the packaging material size being large, causing waste of packaging materials, high warehousing and transportation costs, and high sterilization costs. Summary of the Invention

[0010] The purpose of this invention is to provide a packaging structure for dressing products to alleviate the technical problems existing in the prior art that result in packaging materials sticking to the product, generating a large amount of medical waste, causing inconvenience for medical staff to operate, and making it impossible to directly observe the surface contamination of the product when using release paper and / or release film packaging.

[0011] This invention provides a dressing product packaging structure, comprising a first packaging layer, a second packaging layer, and a dressing product. The dressing product includes a base layer and an adhesive layer coated on the base layer. A packaging space is formed between the first packaging layer and the second packaging layer via a sealing portion, and the dressing product is packaged within the packaging space. A first release agent layer is coated on one side of the first packaging layer on the packaging space side. The adhesive layer of the dressing product is directly adhered to the first release agent layer, and the coating area of ​​the first release agent layer is greater than or equal to the projected area of ​​the adhesive layer.

[0012] Furthermore, the dressing patch product also includes a first release strip and a second release strip respectively pasted on both sides of the adhesive layer in a first direction;

[0013] The sum of the areas of the first release strip and the second release strip is 5% to 80% of the area of ​​the base layer.

[0014] Furthermore, the first release strip and / or the second release strip have a folded-back portion on one side of the dressing patch product inside in the first direction; the folded-back portion bends toward the first encapsulation layer side and folds back toward the outside of the dressing patch product in the first direction.

[0015] Furthermore, the length of the folded-back portion along the first direction is less than or equal to the length of the first release strip along the first direction, and the length of the folded-back portion along the first direction is less than or equal to the length of the second release strip along the first direction.

[0016] Furthermore, the length of the folded-back portion along the first direction is greater than or equal to 0.5 cm.

[0017] Furthermore, when viewed from the side of the dressing patch product where no adhesive layer is provided, the tear-off portion of the first release strip and / or the second release strip is exposed from the edge or corner of the base layer.

[0018] Furthermore, when viewed from the side of the dressing patch product without an adhesive layer, neither the first nor the second release strip is exposed from the base layer.

[0019] Furthermore, the basis weight of the first release strip and the second release strip is 50 g / m². 2 ~300g / m 2 .

[0020] Furthermore, the coating area of ​​the first release agent layer is larger than the projection area of ​​the adhesive layer, and a second release agent layer is coated on the side of the second encapsulation layer facing the encapsulation space. The shape of the second release agent layer is an annular shape that overlaps with the outer periphery of the first release agent layer.

[0021] Furthermore, a core is provided at the center of the adhesive layer, and a through hole is provided at the center of the core; a slit is formed on the dressing product extending from the center of the through hole to the outer edge of the first release strip or the second release strip.

[0022] Furthermore, when the cut is straight, the cut and its extension are perpendicular to the first release strip and the second release strip.

[0023] Furthermore, a region indicator is formed on the first encapsulation layer; a first release agent layer is coated on the region indicated by the region indicator.

[0024] Furthermore, block-shaped positioning marks are formed at the corners of the first encapsulation layer.

[0025] Furthermore, a tear is formed by extending the outer edge of either the first encapsulation layer or the second encapsulation layer.

[0026] Furthermore, the two corners of the edge sealing section facing the tear are rounded.

[0027] Furthermore, the edge of the sealing portion protrudes towards the tear end to form a pointed tip. Beneficial effects:

[0028] The present invention provides a packaging structure for a dressing patch product, including a first packaging layer, a second packaging layer and a dressing patch product, wherein the dressing patch product includes a base layer and an adhesive layer coated on the base layer;

[0029] An encapsulation space is formed between the first and second encapsulation layers via a sealing section, within which the dressing product is encapsulated. By combining a visible packaging layer and a sterile paper packaging layer, an airtight and watertight space is created. After the dressing product is placed in this space and sterilized with ethylene oxide, bacteria can be prevented from growing within the chamber during its shelf life. This enhances the protective capability of the dressing product's encapsulation structure while allowing for observation of whether the dressing core is contaminated. Furthermore, the visibility of the dressing core allows for online detection and removal of contaminated products. If medical personnel discover mold growth or dirt before use, the dressing can be discarded, preventing medical accidents.

[0030] A first release agent layer is coated on one side of the first encapsulation layer, on the encapsulation space side. The adhesive layer of the dressing product is directly adhered to the first release agent layer, and the coating area of ​​the first release agent layer is greater than or equal to the projected area of ​​the adhesive layer. By replacing release paper and / or release film with the adhesive layer covering the dressing product, compared with existing packaging methods, more than 90% of the use of release paper and / or release film can be saved. While saving costs, the dressing product can be directly adhered to the release agent of the dressing product's encapsulation structure through the adhesive layer, making the dressing product and the encapsulation structure an integral unit, preventing displacement and detachment during transportation and storage. When needed, the dressing product's encapsulation structure can be torn open, and the dressing base layer can be directly peeled off from the first encapsulation layer, making operation convenient. Furthermore, by precisely positioning the dressing on the release agent on the surface of the packaging material, the outer packaging size can be reduced, thereby reducing packaging costs, warehousing and logistics costs, and sterilization costs. This invention will bring significant social benefits while reducing costs and medical waste.

[0031] This invention can be configured with two release strips, which is especially convenient for medical staff to operate when fixing dressings that are relatively long, irregularly shaped, or have perforated openings. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] Example 1

[0056] As shown in Figures 1, 2 and 3, the present invention provides a dressing patch product packaging structure, including a first packaging layer 1, a second packaging layer 2 and a dressing patch product 3, wherein the dressing patch product 3 includes a base layer 301 and an adhesive layer 302 coated on the base layer 301.

[0057] An encapsulation space is formed between the first encapsulation layer 1 and the second encapsulation layer 2 via the sealing portion 4, and the dressing patch product 3 is encapsulated within the encapsulation space.

[0058] A first release agent layer 5 is coated on one side of the first encapsulation layer 1 on the encapsulation space side.

[0059] Optionally, depending on the type of dressing patch product 3, a core 303 may be provided at the center of the adhesive layer 302 (e.g., a conventional dressing patch product), or a core 303 may not be provided (e.g., a hydrocolloid dressing patch product, in which case the layer formed by the hydrocolloid or other material of the dressing patch product for direct adhesion to the body is the adhesive layer 302 described in this application).

[0060] The adhesive layer 302 of the dressing patch product 3 is directly pasted onto the first release agent layer 5, and the coating area of ​​the first release agent layer 5 is greater than or equal to the projected area of ​​the adhesive layer 302.

[0061] Specifically, the visible first encapsulation layer 1 is bonded to the dressing product 3 via a first release agent layer 5 and an adhesive layer 302. The second encapsulation layer 2 is the same size as the first encapsulation layer 1 and is stacked together in alignment. A sealing edge 4 is formed by heat-melting or pressing the surfaces of the first and second encapsulation layers 1 and 2 together. After the dressing product 3 is placed in the encapsulation space and sterilized with ethylene oxide, bacteria can be prevented from growing in the chamber during the shelf life. Furthermore, due to its transparency, contamination of the dressing core or adhesive layer 302 on the dressing product 3 can be clearly observed from the first encapsulation layer 1. This visualization of the dressing core allows for online detection and removal of contaminated products. Additionally, if medical personnel discover mold growth or dirt before use, the dressing can be discarded, preventing medical accidents.

[0062] The dressing patch product 3 is coated with an adhesive layer 302. The base layer 301 of the dressing patch product 3 is bonded to the side of the first encapsulation layer 1 coated with the first release agent layer 5 through the adhesive layer 302. The coating area of ​​the first release agent layer 5 is not less than that of the adhesive layer 302, so that the first release agent layer 5 can cover the area of ​​the adhesive layer 302. In addition, the area of ​​the first release agent layer 5 is smaller than the overall area of ​​the first encapsulation layer 1, that is, it does not cover the entire first encapsulation layer 1, so as to prevent the first encapsulation layer 1 and the second encapsulation layer 2 from being unable to achieve heat sealing when the entire first encapsulation layer 1 is covered.

[0063] By coating the first release agent layer 5 onto the first encapsulation layer 1 for adhesion to the adhesive layer 302 of the dressing product 3, one or two large release papers / films that would normally need to be adhered to the adhesive layer 302 can be eliminated, significantly saving costs and reducing medical waste. Furthermore, by directly adhering the adhesive layer 302 to the first encapsulation layer 1, the dressing product 3 and the first encapsulation layer 1 become one unit, preventing displacement and detachment of the dressing product during transportation and storage, avoiding material spillage and packaging adhesion. Moreover, when needed, the dressing product 3 can be easily peeled off from the first encapsulation layer 1 by tearing open the encapsulation structure; and even after tearing open the second encapsulation layer 2, the dressing product 3 remains adhered to the first encapsulation layer 1, meaning the dressing product 3 is less likely to detach unexpectedly when the encapsulation structure is opened.

[0064] It should be noted that the sealing part 4 has at least one side of the first encapsulation layer 1 and the second encapsulation layer 2 that is not sealed along the outer periphery of the first encapsulation layer 1. That is, when the dressing patch product encapsulation structure is torn open, the product encapsulation structure can be torn open on one side by separating the first encapsulation layer 1 and the second encapsulation layer 2.

[0065] Preferably, the first encapsulation layer 1 is a composite film of PE+PET, a composite film of CPP+PET, a PET film, or other visible transparent film. In the case where the encapsulation structure of the above embodiment does not include a large release liner / film, the dressing product 3 can be directly observed through the visible first encapsulation layer 1 to determine if it is contaminated or discolored. The material of the second encapsulation layer 2 is not particularly limited, but is preferably sterile paper. Sterilized paper is airtight and watertight, but allows ethylene oxide to pass through. The dressing product 3 can be sterilized using ethylene oxide, and after sterilization, bacteria will not grow inside the encapsulation structure of the dressing product during its shelf life, achieving a sterile environment.

[0066] It should be noted that after the base layer 301 is removed from the packaging structure of the dressing patch, it is attached to the user's skin using the adhesive layer 302 and then peeled off from the user's skin. Therefore, the base layer 301 of the dressing patch product is a network structure sheet made of fibers or a thin film sheet formed of thermoplastic material, which are common in the art.

[0067] It should be noted that, due to the different adhesive properties and materials of the adhesive layer 302 on the dressing patch product 3, the first release agent layer 5 coated on the first encapsulation layer 1 includes either an organic or inorganic release agent. The release force of the first release agent layer 5 is 3g / 25mm to 60g / 25mm, and the release agent coating amount is 0.1g / m². 2 ~4g / m 2This ensures that the dressing patch product 3 can be easily peeled off from the surface of the first encapsulation layer 1 where the first release agent layer 5 is applied, while also ensuring that the dressing patch product 3 does not unexpectedly fall off from the area of ​​the first release agent layer 5 during transportation and storage.

[0068] It should be noted that the heat sealing temperature for the first encapsulation layer 1 and the second encapsulation layer 2, when the sealing part 4 is heat-sealed, is 100℃~230℃, and the time is 1s~8s. Adhesion of the first encapsulation layer 1 and the second encapsulation layer 2 under these heat sealing temperature and time conditions ensures the strength, stability, and safety of the dressing patch product's encapsulation structure.

[0069] Example 2

[0070] In Embodiment 2 of the present invention, as shown in FIG. 4, the dressing patch product 3 further includes a first release strip 501 and a second release strip 502 respectively adhered to both sides of the adhesive layer 302 in a first direction. Embodiment 2 is identical to Embodiment 1 except that the first and second release strips 501 and 502, which are elongated strips, are adhered to the surface of the base layer 301 along both edges in the first direction via the adhesive layer 302. In this embodiment and the following embodiments, the first direction is the left-right direction in FIG. 4, that is, the tearing direction when separating and tearing apart the first encapsulation layer 1 and the second encapsulation layer 2.

[0071] The sum of the areas of the first release strip 501 and the second release strip 502 can be 5%, 20%, 40%, 50%, or 80% of the area of ​​the base layer 301, preferably 5% to 50%. In this embodiment, it is preferable that the first release strip 501 and the second release strip 502 are the same in terms of size, material, shape, and weight.

[0072] By setting the first release strip 501 and the second release strip 502, the first release agent layer 5 and the adhesive layer 302 can be isolated, preventing them from sticking together. This allows the user to easily remove the dressing product 3 from the first packaging layer 1 from the first release strip 501 and the second release strip 502 after tearing open the dressing product packaging structure.

[0073] The combined area of ​​the first release strip 501 and the second release strip 502 is 5% to 80% of the area of ​​the base layer 301. Compared to the existing technology where the total area of ​​release paper / film exceeds 100% of the base layer 301, this significantly reduces the use of release paper / film. This not only enables direct observation of the core dressing 303 but also greatly reduces costs and the generation of medical waste. Furthermore, only a small portion of the first release strip 501 and the second release strip 502 is needed to facilitate removal from the first encapsulation layer 1.

[0074] Furthermore, as shown in Tables 1 and 2, taking a standard 10cm × 10cm sterile dressing patch product 3 as an example, using the structure of this embodiment 2, the release paper used can be reduced by 80% compared to conventional production. Moreover, in terms of the overall packaging structure, the size can be reduced by 13.65%.

[0075] Table 1

[0076] Table 2

[0077] Example 3

[0078] In Embodiment 3 of the present invention, as shown in FIG5, compared with Embodiment 2, the base layer 301 is circular in this embodiment. The area occupied by the corresponding first release strip 501 and second release strip 502 on the base layer 301 can also be adjusted accordingly. By reasonably adjusting their area on the circular base layer, the area of ​​the first release strip 501 and the second release strip 502 is appropriately increased, so that there is a larger separation contact surface between the base layer 301 and the first encapsulation layer 1, thereby reducing the resistance when removing it, so as to achieve the effect of facilitating the removal of the base layer 301 from the first encapsulation layer 1.

[0079] By adopting the solution of this embodiment, the dressing patch product packaging structure can be used for dressing patch products of more shapes.

[0080] Of course, the shape of the dressing patch product 3 is not limited to a circle; it can also be an oval or kidney-shaped shape. Depending on the actual ease of removal, the area of ​​the first release strip 501 and the second release strip 502 can be reasonably increased or decreased to control the separation force between the base layer 301 and the first encapsulation layer 1. This allows the user to remove the base layer 301 more easily and smoothly, while also ensuring that the base layer 301 maintains good adhesion to the encapsulation layer when it is not removed.

[0081] Example 4

[0082] In Embodiment 5 of the present invention, as shown in FIG6, based on Embodiment 2 above, the first release strip 501 and / or the second release strip 502 have a folded-back portion 503 on one side of the inside of the dressing patch product 3 in the first direction. FIG7 shows the case where both the first release strip 501 and the second release strip 502 have folded-back portions 503, but this is only an example, and the folded-back portion 503 can be provided on only one of them according to the actual situation.

[0083] The folded-back portion 503 bends toward the first encapsulation layer 1 and folds back toward the outside of the dressing patch product 3 along the first direction.

[0084] Preferably, the length of the fold-back portion 503 along the first direction is less than or equal to the length of the first release strip 501 along the first direction. The length of the fold-back portion 503 along the first direction is less than or equal to the length of the second release strip 502 along the first direction.

[0085] Specifically, compared to Embodiment 2, in this embodiment, the first release strip 501 and / or the second release strip 502 form a folded-back portion 503 on the side near the center of the dressing product 3 in the first direction. In the completed encapsulation structure, one side of the folded-back portion 503 contacts the corresponding release strip, and the other side contacts the first encapsulation layer 1. Due to the presence of the folded-back portion 503, which is neither bonded to the adhesive layer 302 nor to the first release agent layer 5, it is easier to remove the first release strip 501 and / or the second release strip 502 from the dressing product 3 after it has been removed from the first encapsulation layer 1.

[0086] The length of the folded-back portion 503 along the first direction is less than or equal to the length of the first release strip 501 and / or the length of the second release strip 502 along the first direction. If the length of the folded-back portion 503 along the first direction is too long, it will not only waste material and increase the amount of medical waste generated, but also exceed the length of the first release strip 501 and / or the second release strip 502 in the corresponding direction, which may cause uneven force when removing the release strip from the dressing patch product 3, resulting in wrinkles in the dressing patch product 3 and thus unexpected adhesion.

[0087] Limiting the length of the folded-back section 503 to the length of the first release strip 501 and / or the second release strip 502 ensures a reasonable distribution of the removal force, making the release strips easier to remove and avoiding unintended wrinkles or adhesion.

[0088] Furthermore, the length of the folded-back portion 503 should be suitable for medical personnel wearing rubber gloves to easily pinch with their fingers, preferably greater than or equal to 0.5 cm. During use, after removing the dressing patch product 3 from the packaging structure, when removing the first release strip 501 and / or the second release strip 502, the user can easily pinch the folded-back portion 503 with their fingers and apply a certain amount of force to complete the corresponding action.

[0089] Example 5

[0090] In Embodiment 5 of the present invention, as shown in FIG7, when viewed from the side of the dressing patch product 3 where the adhesive layer 302 is not provided, the tear-off portion 504 of the first release strip 501 and / or the second release strip 502 is exposed from the edge or corner of the base layer 301.

[0091] Specifically, when viewed from the side of the dressing patch product 3 where the adhesive layer 302 is not provided, at least one corner of the first release strip 501 and the second release strip 502 protrudes from the edge or corner of the base layer 301, and the protruding portion forms a tear-away portion 504.

[0092] In some cases, the corners of the base layer 301 are rounded, while the corners of the first release strip 501 and the second release strip 502, which are bonded to it by the adhesive layer 302, are right angles and have the same length. Thus, the first release strip 501 and the second release strip 502 protrude from the base layer 301, thereby forming the tear-off part 504.

[0093] Because of the presence of the tear-off part 504, when removing the first release strip 501 and the second release strip 502 from the base layer 301, the release strip can be removed by pinching the tear-off part 504, making the operation more convenient.

[0094] Example 6

[0095] In Embodiment 6 of the present invention, as shown in FIG8, the difference from Embodiment 5 above is that, if viewed from the side of the dressing patch product 3 without the adhesive layer 302, the first release strip 501 and the second release strip 502 are not exposed from the base layer 301.

[0096] Specifically, according to the embodiment shown in FIG8, if viewed from the side of the dressing patch product 3 without the adhesive layer 302 (looking outward from the inside of the paper in FIG8), the corners of the base layer 301 are rounded, and the corners of the first release strip 501 and the second release strip 502, which are attached to it by the adhesive layer 302, are also rounded, and the lengths of the two are the same. At this time, the first release strip 501 and the second release strip 502 are covered.

[0097] In this case, after removing the dressing patch product 3 from the packaging structure, it can be first pasted onto the body, and the two sides with the release strip are bent to separate the release strip from the adhesive layer 302. After the release strip has separated from the adhesive layer 302 to a certain extent, it can be removed from the adhesive layer 302.

[0098] This operation requires the release strips to have a certain degree of hardness, therefore the basis weight of the first release strip 501 and the second release strip 502 can be adjusted to 50 g / m². 2 ~300g / m 2 The material is glassine paper or other base paper or plastic film suitable for use as release paper. The first release strip 501 and the second release strip 502 of this weight have greater stiffness, which can achieve the effect of easy peeling from the base layer 301 under the above operation method.

[0099] Furthermore, in a preferred manner of use of this embodiment, after removing the dressing patch product 3 from the packaging structure, the exposed adhesive layer 302 is first pasted onto the surface of the living body. Because the first release strip 501 and the second release strip 502 in this embodiment have high rigidity, the portion of the dressing patch product 3 with the release strip pasted can be flipped upwards, so that the release strips start to separate from the adhesive layer 302 from the inside (the side closer to the inside of the dressing patch product 3). Then, by "pushing", the separation of the already separated release strips 501, 502 and adhesive portion 302 is expanded, while the further separated adhesive portion 302 is adhered and bonded to the surface of the living body.

[0100] According to the solution in this embodiment, the use of dressing products is more convenient and simple, and in some cases, the application of dressing products can be performed with one hand.

[0101] Example 7

[0102] In Embodiment 7 of the present invention, as shown in Figures 9 and 10, a second release agent layer 6 is coated on one side of the second encapsulation layer 2 facing the encapsulation space. The shape of the second release agent layer 6 is an annular shape that overlaps with the outer periphery of the first release agent layer 5, i.e., it can be a square ring, a circular ring, an elliptical ring, or a rounded rectangular ring.

[0103] Specifically, when dealing with dressing products 3 such as hydrocolloid dressings, silicone gel foam dressings, or transparent dressings (PU transparent breathable film) (these products usually do not include a core), it is found that during actual use, due to the material of the adhesive layer 302, edge overflow is very likely to occur during transportation and storage. Once this overflow occurs, the dressing product 3 will adhere to the first encapsulation layer 1 and the second encapsulation layer 2. Consequently, when attempting to separate the first encapsulation layer 1 and the second encapsulation layer 2, the dressing product 3 may be damaged, or the second encapsulation layer 2 may be damaged and remain on the dressing product 3, causing significant inconvenience in use.

[0104] Therefore, in this embodiment, by coating the first release agent layer 5 on the first encapsulation layer 1, the coating area of ​​the first release agent layer 5 being larger than the area of ​​the adhesive layer 302; and by coating the second encapsulation layer 2 with a second release agent layer 6 whose outer periphery is consistent with that of the first release agent layer 5, even if adhesive overflow occurs, the overflowing adhesive will be blocked by the first release agent layer 5 and the second release agent layer 6, and will not come into contact with the first encapsulation layer 1 or the second encapsulation layer 2. This ensures that even if adhesive overflow occurs during packaging and storage, the hydrocolloid dressing product 3 will not affect its subsequent use.

[0105] It should be noted that, as described in Embodiment 1 above, the dressing product 3 in this embodiment is a hydrocolloid dressing product without a core 303. The layer formed by the hydrocolloid or other materials for direct adhesion to the body is the adhesive layer 302. Optionally, a first release strip 501 and a second release strip 502 may also be provided on both sides of the adhesive layer 302 in the first direction.

[0106] At this point, as shown in Table 3, taking a 10cm×10cm hydrocolloid dressing product as an example, using the first release strip 501 and the second release strip 502 in this embodiment can save 93.19% of the release film compared to the existing method of using two large release films to clamp the hydrocolloid dressing from both sides.

[0107] Table 3

[0108] Alternatively, depending on actual production conditions, the second release agent layer 6 can also be made to be the same size and shape as the first release agent layer 5, instead of being made into a ring shape. In this case, it is easier to form the second release agent layer 6.

[0109] Example 8

[0110] In Embodiment 8 of the present invention, as shown in Figures 3 and 11, a core 303 is further provided at the center of the adhesive layer 302 in this embodiment, and a through hole 304 is provided at the center of the core 303. A slit 305 is formed on the dressing patch product 3, extending in a curved manner from the center of the through hole 304 to the outer edge of the first release strip 501 or the second release strip 502.

[0111] Specifically, as shown in Figure 11, a dressing core 303 is provided at the center of the adhesive layer 302. A circular through hole 304 is passed through the center of the dressing core 303. The through hole 304 has ruptured openings around its perimeter to accommodate various types of cannulas. The through hole 304 is used for the passage or fixation of catheters placed on the patient's body. A slit 305 is formed on the dressing patch product 3, extending in a straight line from the center of the through hole 304 to the outer edge of the first release strip 501 or the second release strip 502. The slit 305 is wavy, which makes it less likely for the catheter to detach from the through hole 304 after entering it, thus allowing the catheter to be better fixed.

[0112] The method of using the dressing product 3 in this embodiment is no different from that of the other embodiments described above, except that the catheter needs to be inserted into the through hole 304 before applying the dressing product 3 to the living body. Therefore, compared with the dressing products of the prior art that use two large sheets of release paper / film, it can avoid the inconvenience caused by the interference between the large sheets of release paper / film (whether rigid or soft) and the catheter, greatly improving the convenience and operability of use.

[0113] Example 9

[0114] In Embodiment 9 of the present invention, as shown in FIG12, except for the form of the through hole 304 and the form of the cut 305 which are different from those of Embodiment 8, the rest are the same as those of Embodiment 8, and can be regarded as a simplified version of Embodiment 8.

[0115] In this embodiment, the cut 305 is straight, and the cut 305 and its extension line are perpendicular to the first release strip 501 and the second release strip 502.

[0116] Similar to Embodiment 8 above, this embodiment uses two large sheets of release paper / film for dressings compared to existing technologies. This avoids the operational inconvenience caused by interference between the large sheets of release paper / film (whether rigid or soft) and the catheter, greatly improving ease of use and operability. Furthermore, it has a simple structure and is easy to manufacture.

[0117] Example 10

[0118] In Embodiment 10 of the present invention, as shown in Figures 1, 4, 5, 8, and 10-14, an area indicator 101 is formed on the first encapsulation layer 1; a first release agent layer 5 is coated on the area defined by the area indicator 101.

[0119] A block-shaped positioning mark 102 is formed at the corner of the first encapsulation layer 1.

[0120] Specifically, this embodiment can be combined with the above embodiments. Since the first encapsulation layer 1 and the second encapsulation layer 2 cannot achieve heat sealing due to the influence of the first release agent layer 5 when the entire first encapsulation layer 1 is coated, the area indicator 101 is set to divide the first encapsulation layer 1 into the first release agent layer 5 area and the non-release agent area. This can avoid wasting material by coating too much of the first release agent layer 5 on the first encapsulation layer 1. At the same time, if manual bonding is used for production, the presence of the area indicator 101 can clearly indicate the area where the release agent is located, making it easier to avoid applying the dressing / patch product 3 to the first encapsulation layer 1 outside the release agent area.

[0121] On the automated production line, since both the first packaging layer 1 and the second packaging layer 2 are packaging materials wound on paper tubes, as shown in Figure 15, they need to be cut into pieces during production. Therefore, block-shaped positioning marks 102 are set at the corners of the first packaging layer 1 and the second packaging layer 2. At the same time, on the automated production line, the positioning marks 102 can also accurately locate the release agent area and then accurately attach the dressing patch product 3 within the release agent area. The positioning marks 102 facilitate precise positioning and cutting.

[0122] It should be noted that the area indicator 101 and the positioning mark 102 can be selected from manual or automated production according to actual production needs.

[0123] Example 11

[0124] In Embodiment 11 of the present invention, a tear 7 is formed by extending the outer edge of either the first encapsulation layer 1 or the second encapsulation layer 2.

[0125] Specifically, since the first encapsulation layer 1 and the second encapsulation layer 2 are heat-fused together, if the size of the unsealed area is too small, it may be impossible to tear open the packaging structure of the dressing patch or to separate the two. Since the two are the same length, it is not convenient to pinch them. Therefore, either side of the first encapsulation layer 1 and the second encapsulation layer 2 is extended forward to realize a packaging layer tear 7 with one long and one short, which makes it easy to pinch and separate the two packaging layers at the same time.

[0126] Example 12

[0127] In Embodiment 12 of the present invention, as shown in FIG13, the two corners of the end of the sealing portion 4 facing the tear opening 7 are rounded chamfers 401.

[0128] Specifically, when separating the first encapsulation layer 1 and the second encapsulation layer 2 from the tear opening 7, if the sealing edge 4 is a right angle, the force will be concentrated at the vertex of the right angle, which can easily cause the material of the first encapsulation layer 1 or the second encapsulation layer 2 to tear, resulting in the inability to open the encapsulation structure. However, by setting a rounded chamfer 401, the force area can be distributed to facilitate tearing the encapsulation structure of the dressing product and avoid tearing the material.

[0129] Example 13

[0130] In Embodiment 13 of the present invention, as shown in FIG14, the edge of the sealing portion 4 extends forward from the middle to form a tip portion 402 towards the tear opening 7.

[0131] Specifically, when separating the first encapsulation layer 1 and the second encapsulation layer 2 from the tear opening 7, the first contact is made with the tip 402, and all the tearing force is applied to the tip 402, which makes it easier to tear open the encapsulation structure of the dressing patch product.

[0132] Based on the above embodiments, the packaging process of the dressing patch product packaging structure provided by the present invention is as follows:

[0133] Prepare a first encapsulation layer 1 and a second encapsulation layer 2 of corresponding specifications according to the shape and size of the dressing patch product 3; directly attach the adhesive layer 302 of the dressing patch product 3 to the first encapsulation layer 1 with the first release agent layer 5 applied at intervals; use an automated packaging machine to achieve positioning and attachment or manual attachment to attach the dressing patch product 3 to the first encapsulation layer 1; align the first encapsulation layer 1 and the second encapsulation layer 2, and heat-seal the areas without the first release agent layer 5 to form a well-sealed encapsulation structure.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, and some or all of the technical features can be equivalently replaced or combined. Such modifications, combinations or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
