DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples.

[0019] Figures 1 to 4 The utility model discloses an example.

[0020] Example:

[0021] The wound dressing with analgesic function comprises a first waterproof and breathable cloth 1, and a gel sheet 2 arranged on the front side of the first waterproof and breathable cloth 1, wherein the gel sheet 2 comprises a high molecular gel, purified water, nano silver fibers and analgesics, the front side of the first waterproof and breathable cloth 1 is provided with a waterproof adhesive ring 3 surrounding the gel sheet 2, and the front side of the gel sheet 2 and the waterproof adhesive ring 3 is jointly attached with a release paper 4. By arranging the gel sheet 2 to be attached to the wound of the patient, the purified water is evaporated to cool the wound of the patient, which is beneficial to relieve the pain of the patient and promote wound healing. By arranging the nano silver fibers, the antibacterial and bactericidal functions and the function of removing odor to a certain extent can be achieved, and the risk of wound infection is reduced. By arranging the analgesics, the analgesics can be used externally to relieve the pain of the patient, which is beneficial to the patient to get out of bed. By arranging the waterproof adhesive ring 3, the wound of the patient can be adhered around, the adhesion with the wound is avoided, and the invasion of sweat, exudate and other liquids into the wound from this position is also avoided. The nano silver fibers can quickly kill a plurality of bacteria, such as Escherichia coli, Staphylococcus aureus and Candida albicans, in a short time. The silver ions can be combined with the enzyme protein sulfhydryl in the bacterial cells to make the enzyme lose activity, so as to block the respiration and reproduction process of the bacteria, and achieve the purpose of sterilization. Studies have shown that the nano silver fibers can kill more than 650 kinds of bacteria in a few minutes. Unlike ordinary antibacterial agents, the antibacterial effect of the nano silver fibers has durability. Even after multiple washes, the antibacterial performance can still be maintained, because the silver ions are tightly combined with the fibers by special technology and are not easy to lose. The odor produced by the human body is mainly produced by the decomposition of sweat and other secretions by bacteria. The strong antibacterial ability of the nano silver fibers can reduce the breeding of bacteria, thereby reducing the generation of odor. For example, socks, underwear and the like made of nano silver fibers can effectively remove the odor caused by sweating and the like, and keep the body fresh. The gel contains a certain amount of water, which will gradually evaporate when the gel comes into contact with the skin. In the process of evaporation, water needs to absorb heat from the surrounding, thereby taking away the heat on the surface of the skin to achieve the effect of reducing the local temperature. For example, the ingredients such as high molecular gel and purified water in the fever-reducing patch achieve the cooling effect by using this principle, which is often used to relieve the discomfort caused by cold and fever. Natural cooling ingredients such as menthol and borneol can also be added. These ingredients have volatility and will absorb heat in the process of volatilization, giving people a cooling feeling and assisting in achieving the cooling effect. The nano silver fibers can be directly mixed in the gel sheet 2. The analgesics can also be directly mixed in the gel sheet 2 to be in direct contact with the wound. This way needs to select some analgesics that can be in direct contact with the wound, such as local anesthetics: ropivacaine: a long-acting amide local anesthetic, which can be used for local infiltration anesthesia of surgical wound sites, and can effectively relieve postoperative wound pain. The effect time is relatively long, and the blocking effect on sensory nerves is greater than that on motor nerves, which can reduce the influence on postoperative motor function.Bupivacaine: also a common local anesthetic, can be used for local infiltration injection at the end of the operation, to play a postoperative analgesic effect. But need to pay attention to its cardiotoxicity and neurotoxicity and other adverse reactions.

By setting the release hard board 5 and the protective cover 6, the gel sheet 2 can be protected before the dressing is used, and the gel sheet 2 is isolated from the outside world by the cooperation of the release hard board 5 and the protective groove. By setting the adhesive tape 7, the release hard board 5 and the protective cover 6 can be fixed together. By setting the release adhesive area, the first waterproof and breathable cloth 1 can be fixed to the release hard board 5 before use, and the release hard board 5 and the first waterproof and breathable cloth 1 can be quickly separated during use. And by setting the release hard board 5, the first waterproof and breathable cloth 1 can also be flat before use and when the gel sheet 2 is attached to the patient's wound, avoiding wrinkles and other effects that affect the use effect.

[0023] The first water absorption ring 8 is provided in the gel sheet 2, and the second water absorption ring 9 is provided on the first waterproof and breathable cloth 1. The first water absorption ring 8 and the second water absorption ring 9 are filled with medical cotton rings 10. By setting the first water absorption ring 8 and the second water absorption ring 9 cooperating with the medical cotton ring 10, the liquid and sweat exuded from the patient's wound can be absorbed.

[0024] The rear side of the first waterproof and breathable cloth 1 is attached with a water absorption cotton sheet 11, and the water absorption cotton sheet 11 is attached with the medical cotton ring 10. By setting the water absorption cotton sheet 11, the excess exudate, sweat and the like can be absorbed by the water absorption cotton sheet 11 after the medical cotton ring 10 absorbs water.

[0025] The rear side of the water absorption cotton sheet 11 is covered with a second waterproof and breathable cloth 12, and the edge of the second waterproof and breathable cloth 12 is fixedly attached to the rear side of the first waterproof and breathable cloth 1. By setting the second waterproof and breathable cloth 12, the water absorption cotton sheet 11 can be prevented from being contaminated by external liquid. And by using the second waterproof and breathable cloth 12 and the first waterproof and breathable cloth 1 in the form of adhesion, the water absorption cotton sheet 11 can be replaced by tearing off the second waterproof and breathable cloth 12 after absorbing excess liquid.

[0026] The front side of the gel sheet 2 is recessed near the edge of the gel sheet 2 and is provided with an analgesic ring 13, and the analgesic drug is filled in the analgesic ring 13. Figure 4In addition to the aforementioned analgesics that directly contact the wound, some analgesics that act on the skin around the wound and achieve analgesic effect through skin absorption can also be used, such as flurbiprofen gel patch: the main component flurbiprofen has anti-inflammatory and analgesic effects. When applied to the skin around the wound, it can penetrate the skin and reduce inflammation and pain around the wound. It also has good effects on muscle and joint pain. Ketoprofen gel: similar to flurbiprofen gel patch, it can be applied to the skin around the wound to relieve pain and inflammation. However, it should be noted that it should not come into contact with the wound to avoid irritation. Compound sodium aescinate gel: contains sodium aescinate and diethylamine salicylate, and has the effects of detumescence and analgesia. It can be used for swelling and pain of the tissue around the wound and promote wound healing.
