Description

Technical Field

[0001] This utility model relates to the field of adhesive bandage technology, and in particular to a polygonal variable-shape adhesive bandage based on benzalkonium chloride base material. Background Technology

[0002] Band-aids have evolved from simple gauze and tape to composite materials with various functions such as breathability, water absorption, and antibacterial properties. Their shapes have also become more diverse. In addition to the original rectangle, various shapes suitable for wounds in different parts of the body have emerged, such as joint-shaped and finger-shaped. Furthermore, there are band-aids with medicated ingredients to better promote wound healing, reduce pain, and prevent infection, thus becoming a widely used small wound care product in homes and medical settings worldwide.

[0003] However, current technologies face numerous challenges in treating non-planar skin wounds (such as those around joints or in skin folds) in humid and poorly ventilated environments. Traditional adhesive bandages often fail to adhere completely to these areas, leading to issues like edge lifting and incomplete sealing, exposing the wound to a moist environment and increasing the risk of bacterial growth. Furthermore, ordinary adhesive bandages lack sufficient antibacterial and moisture-absorbing properties in such environments, hindering wound healing. Utility Model Content

[0004] In view of the aforementioned problems in the prior art, the main objective of this invention is to provide a polygonal variable-shape adhesive bandage based on benzalkonium chloride, which addresses the numerous challenges faced by existing technologies in treating non-planar skin wounds (such as those at joints or in skin folds) in humid and poorly ventilated environments. Traditional adhesive bandages often fail to adhere completely to these areas, leading to problems such as edge lifting and incomplete sealing, resulting in wound exposure to a moist environment and increased risk of bacterial growth. Moreover, ordinary adhesive bandages lack sufficient antibacterial and moisture-absorbing properties in such environments, hindering wound healing.

[0005] The technical solution of this utility model is as follows: a polygonal variable-shape adhesive bandage based on benzalkonium chloride base material, including an adhesive bandage, the adhesive bandage being polygonal in shape, the outer side of the adhesive bandage having equidistant tearable dotted lines, the adhesive bandage being made of polyethylene film, super absorbent fiber, acrylic medical adhesive and glassine release paper, a drug layer being fixedly connected to one side of the adhesive bandage, and a medical sponge being fixedly connected to one side of the adhesive bandage and outside the drug layer.

[0006] Through the above technical solution, since the adhesive bandage is polygonal in shape, it can be torn open along the dotted lines according to the shape of the patient's wound. This allows the medicated layer on one side of the bandage to completely conform to the contour of the wound, preventing the bandage from shifting or lifting during joint movement or changes in skin folds. Meanwhile, the polyethylene film, with its flexibility and elasticity, can adapt to the shape changes of non-planar skin, better conforming to joints. The super-absorbent fibers have a strong ability to absorb wound exudate in moist environments, keeping the wound relatively dry. The acrylic medical adhesive has good adhesion and skin compatibility. The glassine release paper protects the acrylic medical adhesive, and the medical sponge provides some hemostasis, preventing blood from affecting the bandage's use.

[0007] In a preferred embodiment, the interior of the drug layer contains benzalkonium chloride, and the exterior of the drug layer is coated with a low-dose erythromycin ointment.

[0008] Through the aforementioned technical solution, the benzalkonium chloride within the drug layer effectively inhibits the growth and reproduction of bacteria around the wound in moist, bacteria-prone environments, creating a favorable antibacterial environment for wound healing. Furthermore, erythromycin, with its antibacterial properties, enhances the adhesive bandage's ability to inhibit common wound infections, further reducing the risk of infection. Its low-dose application aims to minimize the possibility of adverse reactions such as allergies, while simultaneously exerting a synergistic antibacterial effect.

[0009] In a preferred embodiment, the adhesive bandage is fixedly attached to the side away from the medicated layer at equal intervals with double-sided adhesive.

[0010] The above technical solution allows the double-sided adhesive to fix the torn part when the dotted line of the adhesive bandage is torn, thus avoiding affecting the bandage's protection of the wound.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, because the adhesive bandage is polygonal in shape, it is torn open according to the shape of the patient's wound through a tearable dotted line, so that the medicated layer on one side of the adhesive bandage can completely conform to the contour of the wound, preventing the adhesive bandage from shifting or lifting when the joint moves or the skin folds change. At the same time, the polyethylene film has a certain degree of flexibility and elasticity, which can adapt to the shape changes of non-planar skin and better conform to the joint. The super absorbent fiber has a strong ability to absorb wound exudate in a moist environment, which can keep the wound relatively dry. The acrylic medical adhesive has good adhesion and skin compatibility. The glassine release paper is used to protect the acrylic medical adhesive. The medical sponge can play a certain role in stopping bleeding and prevent blood from affecting the use of the adhesive bandage.

[0013] The benzalkonium chloride within the drug layer effectively inhibits bacterial growth and reproduction around the wound in moist, bacteria-prone environments, creating a favorable antibacterial environment for wound healing. Erythromycin, with its antibacterial properties, enhances the bandage's ability to inhibit common wound infections, further reducing the risk of infection. Its low-dose application aims to minimize the possibility of adverse reactions such as allergies, while simultaneously exerting a synergistic antibacterial effect. When tearing the bandage along the perforated line, the double-sided adhesive secures the torn portion, preventing it from compromising the bandage's protective function. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 As shown, this utility model provides a technical solution: including a band-aid 1, the band-aid 1 is polygonal in shape, and the outer side of the band-aid 1 is provided with tearable dotted lines at equal intervals. The band-aid 1 is made of polyethylene film, super absorbent fiber, acrylic medical adhesive and glassine release paper. A drug layer 3 is fixedly connected to one side of the band-aid 1, and a medical sponge 4 is fixedly connected to one side of the band-aid 1 and outside the drug layer 3.

[0020] In this embodiment, since the adhesive bandage 1 is polygonal in shape, it is torn according to the shape of the patient's wound by means of a tearable dotted line, so that the drug layer 3 on one side of the adhesive bandage 1 can completely conform to the contour of the wound, preventing the adhesive bandage from shifting or lifting when the joint moves or the skin folds change. At the same time, the polyethylene film, which has a certain degree of flexibility and elasticity, can adapt to the shape changes of non-planar skin and better conform to the joint. The super absorbent fiber has a strong ability to absorb wound exudate in a moist environment, which can keep the wound relatively dry. The acrylic medical adhesive has good adhesion and skin compatibility. The glassine release paper is used to protect the acrylic medical adhesive. With the medical sponge, it can play a certain role in stopping bleeding and prevent blood from affecting the use of the adhesive bandage 1.

[0021] like Figure 1 , Figure 2 As shown, the interior of drug layer 3 contains benzalkonium chloride, and the exterior of drug layer 3 is coated with a low dose of erythromycin ointment.

[0022] In this embodiment, the benzalkonium chloride within the drug layer 3 effectively inhibits the growth and reproduction of bacteria around the wound in a moist environment conducive to bacterial growth, creating a favorable antibacterial environment for wound healing. Furthermore, erythromycin, with its antibacterial properties, enhances the adhesive bandage's ability to inhibit common wound infection bacteria, further reducing the risk of wound infection. Its low-dose application aims to minimize the possibility of adverse reactions such as allergies, while simultaneously exerting a synergistic antibacterial effect.

[0023] like Figure 1 , Figure 2 As shown, the adhesive bandage 1 is fixedly connected to the side away from the medicine layer 3 with double-sided adhesive 2 at equal intervals.

[0024] In this embodiment, when the dotted line of the adhesive bandage 1 is torn off, the double-sided adhesive 3 can fix the torn part to avoid affecting the protection of the wound by the adhesive bandage 1.

[0025] Working principle:

[0026] like Figure 1 , Figure 2 As shown, since the shape of the adhesive bandage 1 is polygonal, it is torn according to the shape of the patient's wound by means of a tearable dotted line, so that the drug layer 3 on one side of the adhesive bandage 1 can completely conform to the contour of the wound, preventing the adhesive bandage from shifting or lifting when the joint moves or the skin folds change. At the same time, the polyethylene film has a certain degree of flexibility and elasticity, which can adapt to the shape changes of non-planar skin and better conform to the joint. The super absorbent fiber has a strong ability to absorb wound exudate in a moist environment, which can keep the wound relatively dry. The acrylic medical adhesive has good adhesion and skin compatibility. The glassine release paper is used to protect the acrylic medical adhesive. Through the medical sponge, it can play a certain role in stopping bleeding and prevent blood from affecting the use of the adhesive bandage 1.

[0027] The benzalkonium chloride within the drug layer 3 effectively inhibits the growth and reproduction of bacteria around the wound in moist, bacteria-prone environments, creating a favorable antibacterial environment for wound healing. Furthermore, erythromycin, with its antibacterial properties, enhances the bandage's ability to inhibit common wound infections, further reducing the risk of infection. Its low-dose application aims to minimize the possibility of adverse reactions such as allergies, while simultaneously exerting a synergistic antibacterial effect. When the dotted line of the bandage 1 is torn, the double-sided adhesive 3 secures the torn portion, preventing it from compromising the bandage's protective function on the wound.

[0028] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
