Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical dressings, in particular to an antibacterial and comfortable polyurethane foam dressing. Background Art
[0002] Dressings are an important type of medical supplies. Medical dressings are often applied to the patient's wound during surgery, dressing changes and other treatments to stop bleeding and protect the wound, thereby allowing the wound to heal quickly. Specifically, medical dressings are covered on the wound surface of the injured skin, so that before the skin is reconstructed or restored, the medical dressing provides a favorable microenvironment for wound healing. On the one hand, the wound is isolated from the outside world and used to protect the wound. On the other hand, the dressing has the ability to absorb liquid exuded from the wound surface to prevent various problems caused by the exuded liquid.
[0003] For example, a kind of antibacterial and comfortable polyurethane foam dressing in the prior art is closely attached to one side of the polyurethane soft foam body through the polyurethane film layer. The medical dressing composed of the polyurethane soft foam body and the polyurethane film layer has good biocompatibility. The polyurethane soft foam body has a rich porous structure, so it has a good water absorption effect. It also has good physical properties such as high elasticity and good pressure resistance. It can be applied to some parts of the human body that are difficult to cover, and has a good protective effect on the wound and the skin around the wound. At the same time, the polyurethane elastic film has the characteristics of waterproof, breathable, and antibacterial, which can prevent water, bacteria and microorganisms in the environment from entering the wound.
[0004] Since the liquid flowing out of the wound will contaminate the auxiliary material, the user is required to replace the auxiliary material after the liquid exceeds a certain range to avoid damage to the wound. However, when using the auxiliary material, the user cannot more intuitively observe the situation of the polyurethane soft foam being soaked by the liquid, which makes it impossible for the user to replace the auxiliary material at the appropriate time, which can easily cause waste of the auxiliary material or damage to the wound.
[0005] Therefore, it is necessary to provide an antibacterial and comfortable polyurethane foam dressing to solve the above technical problems. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes. Example
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a first embodiment of an antibacterial and comfortable polyurethane foam dressing provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the arc-shaped coating structure shown; Figure 3 for Figure 1 A partial side structural schematic diagram is shown. A bacteria-proof and comfortable polyurethane foam dressing comprises: a polyurethane film 1, wherein a plurality of warning annular rings 11 are arranged on the top of the polyurethane film 1;
[0026] A polyurethane soft foam 2, the polyurethane soft foam 2 is arranged at the bottom of the polyurethane film 1, an anti-inflammatory tablet 21 is arranged at the bottom of the polyurethane soft foam 2, and the anti-inflammatory tablet 21 is arranged at the bottom of the warning annular ring 11;
[0027] The allergic-resistant adhesive 3 is arranged on the bottom of the polyurethane film 1 and is adhered to the bottom of the polyurethane film 1 . The allergic-resistant adhesive 3 is arranged on the outer side of the polyurethane soft foam 2 .
[0028] The plurality of warning annular rings 11 are composed of a plurality of colors, and the sizes of the plurality of warning annular rings 11 are all different.
[0029] Two arc-shaped covering films 31 are arranged at the bottom of the anti-sensitive adhesive 3 , and one end of the two arc-shaped covering films 31 is fixedly connected to a first paddle 32 .
[0030] The bottom of the two arc-shaped coatings 31 are both adhered with an adhesive layer 4 , and the bottom of the adhesive layer 4 is provided with a protective film 41 .
[0031] The protective film 41 is disposed at the bottom of the polyurethane soft foam body 2 .
[0032] A second paddle 42 is fixedly connected to one side of the protective film 41 .
[0033] The polyurethane film 1 is a polyurethane elastic film, which has the functions of air permeability, moisture permeability, bacteria isolation and waterproofing, so that the wound surface maintains a certain temperature and humidity, thereby obtaining a "wound surface microclimate" that is conducive to wound healing. At the same time, the good softness, elasticity and tear resistance of the polyurethane elastic film can make the dressing move with the skin without being easily damaged;
[0034] The polyurethane soft foam 2 has good exudate treatment ability and strong moisture absorption capacity, which can reduce the number of replacements, shorten the wound healing time, and relieve the pain of the patient. On the other hand, since the polyurethane soft foam has good physical properties, such as softness and elasticity, its softness can make it very good for applying to the wound surface, reducing the discomfort and pain of the wound, and its high elasticity makes it easy to apply to various difficult-to-cover parts of the human body;
[0035] The number of circles of the warning annular ring 11 can be set according to the size of the auxiliary material, and the warning annular ring 11 is set from the inside to the outside, and becomes larger from the inside to the outside, and the color is also set from light to dark. In this way, when using it, it is convenient for the user to observe the usage of the polyurethane soft foam 2 according to the depth of the color.
[0036] The working principle of the antibacterial and comfortable polyurethane foam dressing provided by the utility model is as follows:
[0037] When in use, the user pulls the second paddle 42, so that the second paddle 42 drives the protective film 41 and the adhesive layer 4 to move, so that the protective film 41 moves away from the bottom of the polyurethane soft foam 2, and the adhesive layer 4 and the arc-shaped covering film 31 are separated, and then the user aligns the anti-inflammatory sheet 21 with the position of the wound, and then the user pulls the two first paddles 32 respectively, so that the two arc-shaped covering films 31 are separated from the top of the anti-sensitive adhesive 3, and then the anti-sensitive adhesive 3 is adhered to the patient's skin, so as to limit the polyurethane soft foam 2;
[0038] When in use, the anti-inflammatory sheet 21 covers the wound, thereby playing an anti-inflammatory role. The wound exudate is absorbed into the microporous structure of the polyurethane soft foam 2, and then diffuses outward through capillary tension. This moisture absorption mechanism expands the ability of the dressing per unit area to remove liquid from the wound, giving it a longer service life. At this time, the user can check the position of the liquid flow through the warning ring 11 on the polyurethane film 1. When the liquid flows to the bottom of the outermost circle of the warning ring 11, the patient is reminded that the auxiliary material needs to be replaced.
[0039] Compared with the related art, the antibacterial and comfortable polyurethane foam dressing provided by the utility model has the following beneficial effects:
[0040] By cooperating with each other, structures such as the polyurethane film 1, the warning ring 11 and the polyurethane soft foam 2 can facilitate the user to observe the range of the polyurethane soft foam 2 soaked by the liquid flowing out of the wound during use, so that the user can replace the auxiliary materials in time to avoid damage to the wound or waste of auxiliary materials. Example
[0041] Please refer to Figure 4 Based on the antibacterial and comfortable polyurethane foam dressing provided in the first embodiment of the present application, the second embodiment of the present application provides another antibacterial and comfortable polyurethane foam dressing. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0042] Specifically, the difference of the antibacterial and comfortable polyurethane foam dressing provided in the second embodiment of the present application is that, in the antibacterial and comfortable polyurethane foam dressing, a groove 5 is provided at the bottom of the allergic adhesive 3.
[0043] The working principle of the antibacterial and comfortable polyurethane foam dressing provided by the utility model is as follows:
[0044] When in use, a groove 5 is opened on the top of the allergic adhesive 3. When it comes into contact with water, if water enters the inner side of the groove 5, the moisture can be temporarily stored to prevent the moisture from directly passing through the allergic adhesive 3, thereby increasing the waterproof effect.
[0045] Compared with the related art, the antibacterial and comfortable polyurethane foam dressing provided by the utility model has the following beneficial effects:
[0046] The groove 5 is provided to increase the waterproof effect of the allergy-releasing adhesive 3 during use, thereby preventing moisture from directly passing through the allergy-releasing adhesive 3 .
[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
