Description

Technical Field

[0001] This utility model belongs to the field of nursing patch technology, specifically a nursing patch that integrates local cold compress and hemostasis after vaccination. Background Technology

[0002] Nursing patches are products used in the field of medical care. They are usually composed of a variety of materials and are designed to provide protection, treatment, or rehabilitation assistance to specific body parts. During the vaccination process, tiny wounds are formed on the skin. Nursing patches can isolate external bacteria, dust, and other contaminants, reducing the risk of infection. At the same time, they reduce friction on the wound from clothing and other materials, preventing secondary damage to the wound and helping it to heal properly.

[0003] However, the following problems were found in the implementation of the relevant technologies: Existing nursing dressings mostly only have a single hemostatic function. If cold compresses are needed after vaccination to relieve pain and swelling, additional cold compress tools such as ice packs and cold towels are required, making the nursing process cumbersome. This not only consumes more time and manpower but also makes it difficult to achieve rapid treatment in crowded and resource-limited settings such as vaccination sites. At the same time, because the cold compress and hemostatic functions are independent, they cannot form a synergistic effect, failing to provide a more optimized healing environment for the wound, making it difficult to quickly reduce the inflammatory response and blood residue, resulting in lower wound healing efficiency and a relatively higher risk of infection. Furthermore, the connection stability between the cold compress layer and other layers is usually poor, and it is easy to shift or fall off during use, causing the cold compress effect to be inconsistent and unstable, thus affecting the wound care effect of cold compresses. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an integrated post-inoculation local cold compress and hemostasis nursing patch, which has the advantages of integrated function, improved nursing effect, and stable and reliable structure. By integrating cold compress and hemostasis functions into the nursing patch, this invention solves the problem of not being able to provide a more optimized healing environment for the wound; and through the design of positioning posts, limiting balls, and fitting rings, it solves the problem of the cold compress effect not being able to be sustained and stable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a post-vaccination local cold compress and hemostasis integrated nursing patch, comprising a backing layer, a cold compress layer on the lower surface of the backing layer, and a hemostasis layer on the lower surface of the cold compress layer, an adhesive ring fixedly provided on the lower surface of the backing layer, the outer surfaces of the cold compress layer and the hemostasis layer being movably fitted with the adhesive ring, and an isolation layer being adhesively connected to the lower surface of the adhesive ring.

[0006] Preferably, the upper and lower surfaces of the cold compress layer are in close contact with the backing layer and the hemostatic layer, respectively.

[0007] Preferably, the upper surface of the backing layer is fixedly connected with a snap fastener.

[0008] Preferably, the upper surface of the cold compress layer is symmetrically fixed with positioning posts, the upper surface of the backing layer is symmetrically provided with post grooves, and the upper end of the positioning post passes through the corresponding post groove and is fixedly connected with a limiting ball.

[0009] Preferably, the isolation layer has symmetrical tear openings on both sides, and a sealing layer is fixedly provided on the upper surface of the isolation layer, with the upper surface of the sealing layer in movable contact with the hemostatic layer.

[0010] Preferably, the material of the cold compress layer is a polymer hydrogel, and the material of the hemostatic layer is chitosan fiber nonwoven fabric.

[0011] Preferably, the material of the cold compress layer is a polymer hydrogel, and the material of the hemostatic layer is chitosan fiber nonwoven fabric.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model integrates cold compress and hemostasis functions into one nursing patch. Compared with the traditional use of separate cold compress tools and hemostasis products, it simplifies the post-vaccination nursing process, saves nursing time and labor costs, and is especially suitable for rapid treatment at the vaccination site. The cold compress can effectively reduce post-vaccination pain, swelling and inflammatory response, and constrict blood vessels to reduce blood exudation. The hemostasis layer quickly stops bleeding and reduces blood residue. The two work together to provide a good healing environment for the wound, accelerate wound healing, and reduce the risk of infection.

[0013] 2. The cold compress layer and backing layer of this utility model are connected and stabilized by a positioning post and a limiting ball structure, which enhances the stability of the connection between the two and prevents the cold compress layer from shifting or falling off during use, thus ensuring the continuous and stable performance of the cold compress function. The fitting ring fixes and limits the cold compress layer and the hemostatic layer, so that the nursing patch can fit tightly to the injection site and improve the user experience.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides an integrated nursing patch for local cold compress and hemostasis after vaccination, including a backing layer 1, a cold compress layer 2 on the lower surface of the backing layer 1, and a hemostatic layer 3 on the lower surface of the cold compress layer 2. The upper and lower surfaces of the cold compress layer 2 are tightly adhered to the backing layer 1 and the hemostatic layer 3, respectively. An adhesive ring 4 is fixedly provided on the lower surface of the backing layer 1. The outer surfaces of the cold compress layer 2 and the hemostatic layer 3 are movably adhered to the adhesive ring 4. An isolation layer 5 is adhesively connected to the lower surface of the adhesive ring 4. In use, the isolation layer 5 is peeled off, exposing the lower surface of the adhesive ring 4. The nursing patch is then aligned with the vaccination site with the adhesive ring 4 as the boundary, so that the hemostatic layer 3 is in direct contact with the vaccination wound. The cold compress layer 2 covers the hemostatic layer 3, and the backing layer 1 is located on the outermost side. The adhesive ring 4 plays a role in fixing and positioning, ensuring that the cold compress layer 2 and the hemostatic layer 3 are accurately applied to the vaccination site. The tear 52 of the isolation layer 5 makes it easy for the user to peel it off.

[0018] Specifically, the upper surface of the backing layer 1 is fixedly connected with a snap fastener 11, which makes it easy for users to remove the backing layer 1. The overall operation is simple and easy to understand, reducing the difficulty of use and making it suitable for different people. The upper surface of the cold compress layer 2 is symmetrically fixed with positioning posts 21, and the upper surface of the backing layer 1 is symmetrically provided with grooves 12. The upper end of the positioning post 21 passes through the corresponding groove 12 and is fixedly connected with a limiting ball 22. The cold compress layer 2 is connected to the backing layer 1 through the positioning post 21. After the limiting ball 22 at the upper end of the positioning post 21 passes through the groove 12, it restricts the relative movement of the cold compress layer 2 and the backing layer 1 in the horizontal direction, ensuring that the cold compress layer 2 is firmly attached to the lower surface of the backing layer 1. The cold compress layer 2 and the hemostatic layer 3 are tightly attached to each other, ensuring that the cold compress effect can be better transmitted to the hemostatic layer 3 and assisting the hemostatic layer 3 in playing its role.

[0019] Furthermore, tear openings 52 are symmetrically fixed on both sides of the isolation layer 5, and a sealing layer 51 is fixedly provided on the upper surface of the isolation layer 5. The upper surface of the sealing layer 51 is in close contact with the hemostatic layer 3. The tear openings 52 on both sides of the isolation layer 5 make it convenient for users to quickly peel off the isolation layer 5. The isolation layer 5 and the sealing layer 51 effectively protect the hemostatic layer 3 before use to prevent it from being contaminated and ensure that the hemostatic layer 3 in contact with the wound is clean and sterile.

[0020] Furthermore, the material of the second cold compress layer is a high-molecular hydrogel, composed of sodium polyacrylate, sodium carboxymethyl cellulose, glycerin, purified water, etc. An appropriate amount of menthol is added to enhance the cooling sensation. Natural plant extracts such as borneol can also be added, which have cooling, detoxifying, swelling-reducing, and analgesic effects. Utilizing the vaporization of water in the high-molecular hydrogel and the cooling effects of menthol and borneol, heat is carried away from the injection site, causing local vasoconstriction, reducing congestion and swelling, and decreasing the sensitivity of nerve endings, thereby relieving pain. Simultaneously, the cold compress also reduces local blood flow, helping to prevent inflammation and infection. The diffusion of hemostatic layer 3 is specifically made of chitosan fiber nonwoven fabric. Chitosan has good hemostatic properties and can interact with red blood cells in the blood to promote blood coagulation. In addition, a small amount of prothrombin activator is added to accelerate the coagulation process. When the nursing patch is applied to the injection site, hemostatic layer 3 comes into direct contact with the wound. The chitosan fiber nonwoven fabric quickly absorbs the blood seeping from the wound through physical adsorption and chemical action. At the same time, the prothrombin activator activates the prothrombin in the blood, converting it into thrombin, which in turn promotes the conversion of fibrinogen into fibrin to form a blood clot, thus achieving rapid hemostasis.

[0021] It is worth noting that the backing layer 1 is made of polyethylene-polypropylene composite film. This material has good flexibility and strength, which can effectively prevent moisture leakage from the cold compress layer 2, while allowing air to pass through and maintaining air circulation inside the nursing patch. The isolation layer 5 and the sealing layer 51 are made of single-sided silicone paper, which has good anti-stick properties and can effectively prevent the functional layers of the nursing patch from sticking together when not in use, while also being easy to peel off when in use.

[0022] It is worth noting that after vaccination, the skin around the injection site should be cleaned with saline or iodine solution to remove dirt and bacteria and prevent infection. The nursing dressing should be applied after cleaning the skin.

[0023] It is worth noting that during use, it is important to closely observe the injection site, such as whether the bleeding has stopped, whether the swelling has decreased, and whether there are any allergic reactions on the skin. Generally, the nursing patch should be changed every 24 hours. If the nursing patch is found to be contaminated or has lost its cold compress and hemostatic effect, it should be replaced immediately.

[0024] Working principle: When using, peel off the isolation layer 5 to expose the lower surface of the adhesive ring 4. Align the nursing patch with the adhesive ring 4 as the boundary and stick it to the injection site so that the hemostatic layer 3 is in direct contact with the injection wound. The cold compress layer 2 covers the hemostatic layer 3, and the backing layer 1 is located on the outermost side. The adhesive ring 4 plays a role in fixing and positioning, ensuring that the cold compress layer 2 and the hemostatic layer 3 are accurately applied to the injection site. The tear 52 of the isolation layer 5 makes it easy for the user to peel it off. The second cooling layer is made of a high-molecular hydrogel material, which contains a large amount of water and cooling ingredients. When the nursing patch is applied to the injection site, the water in the high-molecular hydrogel slowly evaporates, taking away heat and lowering the local temperature to achieve a cooling effect. At the same time, the cooling ingredients stimulate the skin nerves, further enhancing the cooling sensation, promoting local vasoconstriction, and reducing congestion and swelling. The hemostatic layer 3 is made of chitosan fiber nonwoven fabric. After contacting the inoculation wound, the chitosan fiber uses its positively charged amino groups to generate electrostatic interaction with the cell membrane of negatively charged red blood cells in the blood, causing red blood cell aggregation and accelerating the blood coagulation process. At the same time, the chitosan fiber nonwoven fabric quickly absorbs the blood and tissue fluid seeping from the wound through physical adsorption, thereby achieving hemostasis. The cold compress layer 2 is connected to the backing layer 1 through the positioning post 21. The limiting ball 22 at the upper end of the positioning post 21 passes through the post groove 12 and restricts the relative movement of the cold compress layer 2 and the backing layer 1 in the horizontal direction, ensuring that the cold compress layer 2 is firmly attached to the lower surface of the backing layer 1. The cold compress layer 2 and the hemostatic layer 3 are closely attached to each other, ensuring that the cold compress effect can be better transmitted to the hemostatic layer 3 and assisting the hemostatic layer 3 in playing its role. Before use, the sealing layer 51 on the isolation layer 5 covers the lower surface of the hemostatic layer 3 to prevent the hemostatic layer 3 from being contaminated. During the process of removing the isolation layer 5, the sealing layer 51 is removed along with the isolation layer 5 to ensure the cleanliness of the hemostatic layer 3 so that it can directly and safely contact the wound.
