Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterile dressing technology, specifically to a sterile dressing with disinfection function. Background Technology
[0002] Sterile dressings are a type of medical product similar to "band-aids." They are commonly used consumables for cleaning and bandaging various wounds, promoting wound healing.
[0003] Its main components are water-soluble polymer materials as the matrix framework, rich in 60% water. Through the physical action of effective ingredients such as menthol and hydrogel, it achieves the effect of cold compress therapy, which can reduce joint tissue damage, eliminate swelling and pain, and reduce inflammatory complications. However, existing sterile dressings do not have a disinfection effect. Before use, people should first clean the wound with saline and then disinfect it with iodine before covering it with a sterile dressing. If people are not prepared and do not take disinfection measures, bacteria will multiply around the wound after the dressing is applied, which will further lead to the deterioration and infection of the wound. Utility Model Content
[0004] The purpose of this invention is to provide a sterile dressing with disinfection function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sterile dressing with disinfection function, comprising a non-woven absorbent pad, a pressure-sensitive adhesive non-woven fabric disposed on the top of the non-woven absorbent pad, a pad disposed at the bottom of the pressure-sensitive adhesive non-woven fabric, a storage groove being formed at the bottom of the pad, a cotton cloth disposed inside the storage groove, and disinfectant powder disposed at the bottom of the cotton cloth.
[0006] Preferably, the bottom of the nonwoven absorbent pad is provided with a nonwoven core, and the outside of the nonwoven core is provided with a PE film.
[0007] Preferably, release paper A and release paper B are disposed below the nonwoven fabric core.
[0008] Preferably, the release paper B is located below the release paper A, and the release paper B and the release paper A are arranged together.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] This invention utilizes a pressure-sensitive adhesive nonwoven fabric with a pad at its bottom. Through the synergistic effect of cotton cloth and disinfectant powder, the cotton cloth and disinfectant powder inside the pad create a sealed space that is tightly fitted around the wound. The disinfectant powder itself possesses powerful disinfecting properties, effectively isolating external bacteria and preventing them from entering the wound through potential gaps. This significantly reduces the risk of wound deterioration or infection. This design not only improves the convenience of wound care but also enhances the safety of the wound healing process.

[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] Please see Figure 1-4This utility model provides a technical solution: a sterile dressing with disinfection function, including a non-woven absorbent pad 1, a pressure-sensitive adhesive non-woven fabric 5 on top of the non-woven absorbent pad 1, a pad 6 at the bottom of the pressure-sensitive adhesive non-woven fabric 5, a storage groove 7 at the bottom of the pad 6, a cotton cloth 8 inside the storage groove 7, and disinfectant powder 9 at the bottom of the cotton cloth 8. Through the arrangement of the pressure-sensitive adhesive non-woven fabric 5 and the pad 6 at the bottom of the pressure-sensitive adhesive non-woven fabric 5, the cotton cloth 8 and the disinfectant powder 9 inside the pad 6 together construct a closed space, tightly placed around the wound. The disinfectant powder 9 itself has a strong disinfection effect, effectively isolating external bacteria and preventing them from entering the wound through potential gaps, thereby significantly reducing the risk of wound deterioration or infection. This design not only improves the convenience of wound care but also enhances the safety of the wound healing process.
[0018] The non-woven absorbent pad 1 has a non-woven core 2 at its bottom, and the non-woven core 2 is covered with a PE film. The non-woven core 2 is located at the bottom of the non-woven absorbent pad 1, which increases the thickness and softness of the entire dressing, making the dressing more comfortable and reducing pressure on the wound. This structure helps to improve the patient's comfort and promote the rapid healing of the wound.
[0019] The nonwoven fabric dressing core 2 has release paper A4 and release paper B3 underneath. The PE film is a waterproof and breathable membrane that is placed on the outside of the nonwoven fabric dressing core 2. It can effectively prevent external liquids and bacteria from penetrating, while allowing air circulation and reducing the dampness and stuffiness under the dressing. This design protects the wound from contamination and maintains the breathability of the dressing area, providing a safer and drier healing environment for the wound.
[0020] Release paper B3 is located below release paper A4. Release paper B3 and release paper A4 are positioned below the non-woven fabric core 2. Their main function is to protect the adhesiveness of the pressure-sensitive non-woven fabric 5 when the dressing is not in use, preventing it from adhering to other objects prematurely. Release paper B3 is located below and positioned with release paper A4. This design makes it easier to remove the release paper, removing both release papers at once, simplifying the usage process, while ensuring that the dressing can adhere firmly to the wound when used for the first time.
[0021] Working principle: When needed, first peel off release paper A4 and release paper B3 to expose pressure-sensitive non-woven fabric 5. Then place the dressing on the treated wound. The non-woven absorbent pad 1 begins to absorb the fluid seeping from the wound. At the same time, the disinfectant powder 9 located in the storage tank 7 begins to disinfect the wound. Since the disinfectant powder 9 is fixed in the storage tank 7 by cotton cloth 8, it will not directly contact the wound, thus avoiding possible irritation and discomfort. The design of the entire dressing ensures the cleanliness and disinfection of the wound while providing a breathable and comfortable nursing environment.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
