Description

Technology Field

[0001] The present disclosure relates to an adhesive patch having a detachable cover. Background Technology

[0002] Medical day bandages or patches used to protect wounds or affected areas of the skin are widely used to block the affected area from the external environment, maintain cleanliness, and prevent secondary infection. A typical medical day bandage has a structure in which an absorbent pad is laminated on a base film containing an adhesive layer.

[0003] The adhesive layer (base film) adheres uniformly to the skin surface to ensure the day bandage remains stable for a certain period. It is designed to minimize skin irritation while preventing the bandage from easily detaching due to environmental changes such as moisture or sweat. Additionally, the adhesive layer seals the edges of the day bandage along the surrounding skin, preventing external foreign substances or bacteria from penetrating the affected area.

[0004] Absorbent pads rapidly absorb blood, body fluids, or exudate discharged from the wound, preventing the wound from becoming excessively wet or contaminated. This maintains a moist environment suitable for wound healing, and the pad also protects the wound from external impact or friction by acting as a buffer layer in direct contact with the wound.

[0005] However, conventional medical day bandages have limitations in that they cover the wound from the outside, making it difficult to frequently check the condition of the wound (such as the presence of bleeding, amount of exudate, and signs of infection). Because it is difficult to immediately detect changes or abnormalities in the wound, the wound may become excessively moist or contaminated and left untreated for a long time, which can cause scarring or delay wound healing.

[0006] In addition, due to the structural characteristics of day bandages, which are in continuous contact with the skin, friction occurs depending on movement or external stimuli. This friction can directly irritate the affected area, causing pain or reopening the wound, and increases the likelihood of secondary infection by allowing residual bacteria or contaminants to penetrate the wound.

Specific details for implementing the invention

[0013] Before specifically describing the embodiments of this specification, the objectives appearing in the field of medical adhesive patches in which the embodiments of this specification are implemented, and the technical means that can be considered to solve them, will be introduced in sequence.

[0014] The field of medical adhesive patches exhibits the following limitations. First, conventional day bandages have a flat structure in which the substrate and pad come into direct contact with the wound, which can cause direct friction with the wound due to external impact or user movement. This friction not only causes pain but also irritates the wound, potentially delaying recovery or leading to scar formation. Second, due to the structural characteristics of general adhesive patches that completely cover the wound, it is difficult to frequently check the condition of the wound—such as dryness, changes in exudate, or signs of infection—while it is attached. Consequently, it is difficult to replace or manage the patch in a timely manner according to the wound condition, which can lead to negative consequences such as secondary infection or excessive moisture. Third, despite the fact that wound size, protrusion, and recovery stage vary by individual and by site, conventional adhesive patches use a method where a pad of a fixed thickness uniformly covers the wound. This presents a problem in that it is difficult to provide differential space or adjust the intensity of protection according to the wound healing stage.

[0015] Based on the recognition of these problems, the present disclosure proposes a new type of medical adhesive patch technology that includes a protruding structure capable of securing space between the affected area and the patch, minimizes friction through coupling with an outer cover, and allows for easy verification of the condition of the affected area.

[0016] Embodiments of the present disclosure will be described in detail below with reference to the drawings. However, detailed descriptions of known functions or configurations that may obscure the essence of the present disclosure in the following description and the attached drawings are omitted. Additionally, throughout the present disclosure, the term "comprising" any component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0019] FIG. 1 is a drawing illustrating the configuration of an adhesive patch equipped with a cover according to one embodiment of the present disclosure.

[0020] Referring to FIG. 1, an adhesive patch equipped with a cover according to one embodiment of the present disclosure comprises an adhesive sheet (10) that is attached to a user's skin and provides support for a protruding container (15), a container cover (20) that protects the user's affected area from the external environment, and a protruding container (15) that is integrally formed with the adhesive sheet in the center of the adhesive sheet (10) to form a spaced-apart space between the affected area and the container cover (20). Additionally, the container cover (20) is coupled to the outer surface of the protruding container (15) and covers the upper opening of the protruding container (15) to perform the function of protecting the affected area.

[0021] The above components are described in more detail below.

[0022] The adhesive sheet (10) is a component that is directly attached to the user's skin and provides support for the entire cover-equipped adhesive patch. The adhesive sheet (10) may be formed of a flexible material to stably adhere to the skin surface that bends according to the user's movements, and materials such as polyurethane (PU) film, non-woven fabric, or medical adhesive film may be used.

[0023] Additionally, the lower surface of the adhesive sheet (10) may include a medical adhesive that adheres to the skin, and a protruding container (15) may be integrally formed or attached to the upper surface. The adhesive sheet (10) seals the area around the affected site to suppress the penetration of external contaminants and provides a structural base that stably supports the protruding container (15).

[0025] The protruding container (15) is a container portion formed to protrude upward from the center of the adhesive sheet (10), forming a gap between the affected area and the container cover (20) to prevent direct contact with the affected area. The protruding container (15) can be implemented in various shapes such as cylindrical, elliptical, or polygonal, and its height and circumference can be designed to be large enough to accommodate the affected area.

[0026] Additionally, the protruding container (15) is formed integrally with the adhesive sheet (10) to maintain a stable structure when attached to the skin, and can be formed from a material such as plastic, silicone, or synthetic resin having a certain rigidity as needed. Furthermore, on the outer surface of the protruding container (15), a coupling structure such as a coupling projection, a locking tab, or a coupling groove can be provided so that the container cover (20) can be snap-coupled, or a threaded projection can be provided so that rotational locking coupling (screw-type coupling) can be enabled. Through this, the container cover (20) can be snap-coupled to the coupling structure provided on the outer surface of the protruding container (15) or coupled in a manner such as rotational locking coupling (screw-type coupling).

[0028] The container cover (20) is configured to cover the upper opening of the protruding container (15) to protect the affected area from the external environment. The container cover (20) is formed to be coupled to the outer surface of the protruding container (15) and may be formed of a silicone, rubber, or soft plastic material capable of elastic deformation.

[0029] In one embodiment of the present disclosure, the container cover (20) may be formed of a transparent or translucent material so that the user can visually check the condition of the wound and the recovery process without exposing the wound. This transparency improves user convenience by allowing the progress of wound healing to be continuously observed even when the wound is not exposed to the external environment, and also contributes to minimizing secondary infection by reducing unnecessary removal of the cover.

[0030] Materials that can be used to ensure transparency of the container cover (20) include various materials having light-transmitting properties, such as medical-grade transparent silicone, polycarbonate (PC), PET or PETG, transparent polypropylene (PP), transparent TPU, etc.

[0031] For example, medical-grade transparent silicone provides excellent elastic recovery while ensuring a light transmittance of over 80%, so it can be stably snap-bonded to a bonding structure provided on the outer surface of the protruding container (15). In addition, polycarbonate (PC) provides a high light transmittance of about 88-90% and impact strength, so it can maintain transparency even when molded into a thin thickness, and PET or PETG is suitable for medical use due to its excellent lightness and biocompatibility. In the case of polypropylene (PP), it can be molded into transparent or translucent forms and has high drug resistance, allowing it to be used stably in various environments, and TPU material has flexibility and transparency similar to silicone, so that the container cover (20) adheres to the protruding container (15) without deformation when bonded.

[0032] In this way, the container cover (20) can be selected from a material combination that allows for smooth snap coupling or rotation locking coupling, and as a result, sufficient transparency is secured to enable observation of the affected area, while maintaining coupling stability with the protruding container (15).

[0033] Additionally, the container cover (20) may be formed with a breathable structure (e.g., forming air passage holes) or a sealed structure according to the embodiment, so that it can be selectively used depending on the moistness of the affected area or for protection purposes. Meanwhile, when a breathable structure is applied, a silver nano-coated antibacterial sticker that can be temporarily attached to the inner or outer surface of the container cover (20) may be additionally added and used according to the user's choice.

[0034] The container cover (20) and the protruding container (15) may be made of materials such that a stable mutual coupling structure is implemented, and the container cover (20) can secure transparency that enables visual inspection of the affected area. That is, for the purposes of this disclosure, the container cover (20) is required to maintain a transparent or translucent state while possessing elasticity or strength that allows for smooth snap coupling or rotation locking coupling with the protruding container (15). As an example of a combination to satisfy these requirements, the protruding container (15) may be formed from a plastic or synthetic resin material that provides a certain degree of rigidity, and the container cover (20) may be formed from a material such as medical transparent silicone, transparent TPU, transparent polycarbonate (PC), or PETG, which has excellent light transmittance and allows for elastic deformation. By being configured in this way, the container cover (20) can maintain sufficient transparency to allow observation of the recovery state of the affected area, and at the same time, can be firmly fastened to the coupling structure of the protruding container (15) without deformation.

[0036] FIG. 2 is a drawing illustrating a protruding container configured to enable snap coupling according to one embodiment of the present disclosure.

[0037] Referring to FIG. 2, the outer surface of the protruding container (15) may be provided with a protrusion having a projection (16) formed along its circumference so that the container cover (20) can be engaged through elastic deformation. The projection (16) may be formed to correspond to a locking groove or a locking projection formed on the inner surface of the container cover (20), and when the container cover (20) is mounted under pressure from above or the side, the container cover (20) undergoes elastic deformation and passes over the projection (16) to be seated in the engagement position.

[0038] The protrusion (16) can be formed with a structure having a certain height and thickness to prevent the container cover (20) from detaching after joining, and can be integrally molded with the protruding container (15) to withstand deformation that may occur during snap joining.

[0040] FIG. 3 is a drawing showing a state in which a container cover according to one embodiment of the present disclosure is snap-coupled to a protruding container.

[0041] Referring to FIG. 3, the container cover (20) is maintained in a connected state by passing over the projection (16) formed along the outer surface of the protruding container (15), and at this time, the locking structure formed on the inner surface of the container cover (20) and the projection (16) interlock to provide a connecting force.

[0042] The container cover (20) is formed of an elastically deformable material (e.g., medical transparent silicone, TPU, etc.) so that it can be deformed along the protrusion (16) and mounted, and after assembly, it is restored to its original shape and adheres to the protruding container (15).

[0043] This snap-joint structure provides a stable connection so that the container cover (20) does not easily detach due to external impact or user movement, while simultaneously allowing the user to easily detach the container cover (20) to manage or replace the affected area when necessary. In addition, when connected, a gap is maintained between the protruding container (15) and the container cover (20) for the affected area, thereby performing a protective function to prevent the affected area from coming into direct contact with the cover or the external environment.

[0045] FIG. 4 is a drawing illustrating a protruding container configured to enable a rotation locking coupling (screw coupling) according to another embodiment of the present disclosure.

[0046] Referring to FIG. 4, a screw thread or a protruding ridge (17) for rotational connection may be formed along the circumferential direction on the outer surface of the protruding container (15) so that the container cover (20) can be secured through rotational movement. This rotational connection structure (17) may be designed to be coupled with a corresponding screw part or a rotational locking groove provided on the inner surface of the container cover (20), and the user may reach the connection position by pressing the container cover (20) from the upper side of the protruding container (15) and then performing a predetermined rotational movement (e.g., clockwise rotation).

[0047] The rotational coupling structure (17) formed on the protruding container (15) can be designed to have an appropriate height and slope to prevent unintentional loosening after the container cover (20) is coupled, and can be formed to maintain an appropriate torque so that the user can easily fasten and unfasten it.

[0049] FIG. 5 is a drawing showing a state in which a container cover according to one embodiment of the present disclosure is rotationally locked and coupled with a protruding container.

[0050] Referring to FIG. 5, the container cover (20) is fastened in a state where a corresponding structure is engaged with a rotational coupling structure (17) formed along the outer surface of the protruding container (15), and is fixed in a locked position by the user performing a rotational operation in a designated direction. This rotational locking coupling provides a stable coupling force that prevents the container cover (20) from being arbitrarily released by external force or vibration during normal use, while allowing it to be easily separated by rotational operation in the opposite direction when detachment is required. In addition, in the rotationally coupled state, a gap space for the affected area is maintained between the protruding container (15) and the container cover (20), thereby ensuring protective performance by preventing the affected area from coming into direct contact with the container cover (20) or the external environment. The container cover (20) may be made of a transparent material, so the condition of the affected area can be continuously observed even when fastened.

[0052] FIG. 6 is a drawing illustrating various aspects of a container cover according to embodiments of the present disclosure.

[0053] Referring to FIG. 6, the container cover (20) performs the basic function of protecting the affected area, and depending on the embodiment, it may be formed as either a sealed structure (21) or a breathable structure (22).

[0054] When implemented as a ventilation structure (22), a plurality of ventilation holes may be formed on the upper side of the container cover (20) so that air or steam can be discharged to the outside, and these ventilation holes may be designed to control the degree of drying or ventilation of the affected area according to the size, number, and arrangement of the holes. In addition, the ventilation holes may be formed to include small ventilation holes or a filter layer to prevent the inflow of external foreign substances.

[0055] According to another embodiment of the present disclosure, a predetermined air hole may be formed on the upper side of the container cover (20). The air hole may be formed to be closed when the screw-coupled protruding container (15) is fully secured, and conversely, the air hole may be configured to gradually become exposed to allow ventilation during the process of separating the container cover (20) by rotating it.

[0056] In the case of a sealed structure (21), no ventilation holes are formed, so a moist environment can be maintained for the affected area, and the container cover (20) is formed of a transparent or translucent material so that the recovery status of the affected area can be visually checked from the outside.

[0058] FIG. 7 is a diagram illustrating a configuration in which an antibacterial sheet according to one embodiment of the present disclosure is attached between an adhesive sheet and skin.

[0059] Referring to FIG. 7, an antibacterial sheet (18) providing antibacterial function may be placed on the skin contact surface of the adhesive sheet (10), which effectively blocks external contaminants, bacteria, or dust from penetrating around the affected area during use. The antibacterial sheet (18) may be formed integrally with the adhesive sheet or attached separately, and may be implemented in various forms such as an antibacterial coating layer, an antibacterial film, or an antibacterial treated nonwoven fabric.

[0060] The antibacterial sheet (18) provides a sealing effect along the periphery of the affected area when the adhesive sheet adheres to the skin, thereby preventing contaminants from entering the gap formed inside the protruding container. This attachment configuration of the antibacterial sheet improves the performance of protecting the affected area and ensures safety by preventing the affected area from coming into direct contact with the external environment, even while keeping the container cover transparent.

[0062] FIG. 8 is a drawing showing an ointment capsule attached to the inner surface of a protruding container according to one embodiment of the present disclosure.

[0063] Referring to FIG. 8, a plurality of ointment capsules (19) for supplying medicine to the affected area may be attached to the inner surface of the protruding container (15). The ointment capsules (19) are formed to break or open when a certain pressure is applied, and may be configured so that when a user presses the inner surface of the protruding container (15), the ointment inside the capsule is released into a spaced-out space inside the protruding container. Additionally, the ointment capsules may be formed with a structure in which an ointment sealed with a vinyl or film-type packaging material is attached to the inner surface of the protruding container (15), and may be configured so that the ointment is released into the space inside the protruding container when the user removes the vinyl as needed.

[0064] An ointment capsule according to one embodiment of the present disclosure may be configured such that when a user presses the outer side of a protruding container (15) while the container cover (20) is attached, the ointment inside the capsule is released into a spaced-out space inside the protruding container. To this end, even if the entire protruding container (15) is formed of a rigid material, the area where the ointment capsule (19) is placed may be formed relatively thin to facilitate pressure transmission, or an elastic material such as silicone or TPU may be partially applied. Accordingly, when a user presses the area from the outside, pressure is transmitted to the ointment capsule (19), and the medicine inside the capsule can be released.

[0065] Alternatively, the protruding container (15) may be formed as a multi-material molded structure in which a rigid plastic material and an elastic material are mixed. For example, TPU or silicone is molded in the area where the ointment capsule (19) is placed, and the area is elastically deformed by hand pressure, allowing the capsule to be crushed or opened.

[0066] Alternatively, the ointment capsule (19) may be designed to have a low breaking pressure so that even if the protruding container (15) is formed of a rigid material, the capsule can be crushed or opened by only external hand pressure.

[0067] Alternatively, an opening or a push window may be formed in a part of the side wall of the protruding container (15) to allow access to the ointment capsule (19), and the part may be finished with an elastic material such as silicone or TPU so that force can be transmitted to the capsule when the user applies pressure from the outside.

[0068] Through this, the user can directly supply the necessary medication to the affected area without exposing the affected area to the outside, and can perform the application of ointment and the attachment of a patch simultaneously in a single configuration. The ointment capsule (19) can be implemented in the form of a medical film pouch, a micro-fragmented capsule, or a gel capsule that releases its contents upon deformation, and may contain various medications such as disinfectants, antibiotics, and wound healing promoters if necessary. Additionally, by arranging multiple ointment capsules at intervals, the user can control the selective release of medication at a desired time.

[0070] effect

[0071] The adhesive patch equipped with a cover according to the present disclosure provides various effects that simultaneously improve user convenience and hygiene while reliably protecting the affected area from the external environment. First, a protruding container formed to protrude from the center of the adhesive sheet secures a gap between the affected area and the container cover, thereby preventing the affected area from coming into direct contact with external objects or the container cover and effectively reducing secondary damage caused by pressure or friction. In addition, a coupling projection or a rotational coupling structure provided on the outer surface of the protruding container allows the container cover to be reliably fastened using a snap coupling or rotational locking coupling method, thereby providing stability that maintains the coupled state even under user movement or external impact.

[0072] Since the container cover can be formed from a transparent or translucent material, the recovery process can be continuously observed even when the affected area is not exposed to the outside, thereby minimizing unnecessary removal and reattachment and facilitating hygienic management for the user. In addition, the container cover can be selectively configured as either a sealed structure or a ventilated structure according to the embodiment, allowing it to accommodate various treatment conditions, such as maintaining a moist environment or promoting drying of the affected area depending on the condition of the wound. In particular, in the case of a ventilated cover, air or water vapor can be discharged to the outside through the ventilation holes, thereby ensuring ventilation of the affected area.

[0073] Furthermore, in an embodiment where an antibacterial sheet is attached between the adhesive sheet and the skin, external contaminants or bacteria can be blocked from penetrating into the gap inside the protruding container, thereby further improving the wound protection performance. By sealing the area around the wound in conjunction with the adhesive sheet, the antibacterial sheet reduces the risk of secondary infection that may occur during wound care.

[0074] As such, the present disclosure provides superior functionality compared to existing daybands or patches in terms of wound protection, hygiene, ease of observation, bonding stability, and application flexibility, and has scalability to respond to various situations and types of wounds.

[0076] In the specific embodiments of the present disclosure described above, the components included in the disclosure are expressed in a singular or plural form according to the specific embodiments presented. However, the singular or plural expressions are selected to suit the situations presented for convenience of explanation, and the present disclosure is not limited to singular or plural components; even if a component is expressed in the plural, it may be composed of a singular form, or even if a component is expressed in the singular form, it may be composed of a plural form.

[0077] Meanwhile, although specific embodiments have been described in the detailed description of the present disclosure, it is understood that various modifications are possible within the scope of the present disclosure. Therefore, the scope of the present disclosure should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
