Description

Technical Field

[0001] This utility model relates to the field of medical dressing technology, specifically to a hydrophilic fiber dressing. Background Technology

[0002] Hydrophilic fiber dressings are medical dressings made of hydrophilic polyurethane foam. They have good breathability and moisture absorption, which helps keep the skin around the wound dry and comfortable, and quickly absorbs the fluid from the wound, keeping the wound clean, reducing the risk of infection, and promoting wound healing.

[0003] Existing hydrophilic fiber dressings are generally adhered to the outer end of the wound via an adhesive layer. However, the adhesive layer at the inner end of the fiber dressing is usually quite wide and located at the four sides of the dressing. As a result, when tearing the dressing during dressing changes, the wound is easily subjected to some tearing traction force, making it inconvenient to remove easily in the early stages of wound healing. Therefore, we propose a hydrophilic fiber dressing. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A hydrophilic fiber dressing includes: a water-blocking base layer, a quick-tear portion provided on the water-blocking base layer, a quick-tear strip provided on one side of the quick-tear portion, an outer adhesive layer and an inner adhesive layer respectively provided on the outer and inner sides of the inner end of the water-blocking base layer, a sweat-absorbing cotton ring provided on the inner end of the water-blocking base layer, an antibacterial cotton ring provided on the inner ring of the sweat-absorbing cotton ring, and a foam absorption layer provided on the inner ring of the antibacterial cotton ring.

[0007] Preferably, a first PU film ring is also provided on the inner side of the sweat-absorbing cotton ring.

[0008] Preferably, a second PU film ring is also provided on the inner side of the antibacterial cotton ring.

[0009] Preferably, the quick-tear portion is located between the outer adhesive layer and the inner adhesive layer.

[0010] Preferably, the foam absorbent layer is made of hydrophilic polyurethane foam.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] 1. In this utility model, the quick-tear part set on the outer edge of the water-blocking base layer can quickly separate the part of the water-blocking base layer in contact with the wound during the replacement of the fiber dressing. Then, the smaller inner adhesive layer at the inner end can be torn off and the part of the inner end in contact with the wound can be removed. This avoids the problem of tearing and pulling the inner end wound after the larger area of ​​the adhesive layer at the inner end is torn off during the overall replacement of the water-blocking base layer. At the same time, the outer adhesive layer at the outer end of the water-blocking base layer that is not torn can also be used as a positioning in the subsequent replacement of the fiber dressing for quick and accurate pasting.

[0013] 2. In this utility model, the sweat-absorbing cotton ring and antibacterial cotton ring set on the outside of the foam absorption layer at the inner end of the water-blocking base layer can respectively absorb sweat and inhibit bacteria on the outside of the foam absorption layer during use, thereby providing external protection for the quick-tear part set on the outer end of the water-blocking base layer. In addition, the first PU film ring and the second PU film ring set on the inner end of the sweat-absorbing cotton ring and the antibacterial cotton ring respectively can also reduce the seepage problem between adjacent ones, thereby improving their respective sweat absorption and antibacterial effects.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a hydrophilic fiber dressing.

[0021] Example 1:

[0022] Combination Figure 1-3As shown, the present invention provides a hydrophilic fiber dressing, comprising: a water-blocking base layer 100, a quick-tear portion 101 provided on the water-blocking base layer 100, a quick-tear strip 102 provided on one side of the quick-tear portion 101, an outer adhesive layer 103 and an inner adhesive layer 104 respectively provided on the outer and inner sides of the inner end of the water-blocking base layer 100, a sweat-absorbing cotton ring 105 provided at the inner end of the water-blocking base layer 100, an antibacterial cotton ring 106 provided in the inner ring of the sweat-absorbing cotton ring 105, a foam absorption layer 109 provided in the inner ring of the antibacterial cotton ring 106, a first PU film ring 107 provided on the inner side of the sweat-absorbing cotton ring 105, a second PU film ring 108 provided on the inner side of the antibacterial cotton ring 106, the quick-tear portion 101 being located between the outer adhesive layer 103 and the inner adhesive layer 104, and the foam absorption layer 109 being made of hydrophilic polyurethane foam.

[0023] Specifically, the hydrophilic fiber dressing is a medical dressing made of hydrophilic polyurethane foam, possessing excellent breathability and moisture absorption. The quick-tear section 101 on the outer edge of the water-resistant base layer 100 allows for rapid separation of the inner portion of the water-resistant base layer 100 from the wound during dressing replacement via the quick-tear strip 102. This allows for the removal of the inner portion from the wound after tearing off the smaller inner adhesive layer 104, avoiding the tearing and traction on the wound caused by tearing off a larger area of ​​the inner adhesive layer during overall replacement of the water-resistant base layer 100. This is beneficial for use in the early stages of wound healing, ensuring effective wound recovery. Simultaneously, the water-resistant base layer... The non-tearable outer adhesive layer 103 at the outer end of the 100 can also be used for positioning during subsequent fiber dressing replacement, enabling quick and accurate adhesion. The sweat-absorbing cotton ring 105 and antibacterial cotton ring 106 set on the outside of the foam absorption layer 109 at the inner end of the water-blocking base layer 100 can respectively absorb sweat and inhibit bacteria on the outside of the foam absorption layer 109 during use, thereby providing external protection for the quick-tear part 101 set at the outer end of the water-blocking base layer 100. In addition, the first PU film ring 107 and the second PU film ring 108 set on the inner end of the sweat-absorbing cotton ring 105 and the antibacterial cotton ring 106 can also reduce the seepage problem between adjacent ones, thereby improving their respective sweat absorption and antibacterial effects.

[0024] Working principle and usage process of this utility model:

[0025] When changing the fiber dressing at the outer end of the patient's wound, first gently tear the quick-tear section 101 open using the quick-tear strip 102 on one side of the quick-tear section 101. After the quick-tear section 101 is completely torn open, the outer adhesive layer 103 at the outer end will separate from the inner adhesive layer 104 at the inner end. At this time, gently peel off the inner adhesive layer 104 and tear off the small width of the inner adhesive layer 104. Then, without pulling or tearing the wound, the sweat-absorbing cotton ring 105, antibacterial cotton ring 106, and foam absorbent layer in the center of the water-resistant base layer 100 can be removed. Remove the entire 109 piece to ensure that there is no pulling or touching of the wound when changing the fiber dressing, so that the wound can heal better. Then, overlap the outer adhesive layer 103 of the new fiber dressing with the reserved outer adhesive layer 103 to cover it, and the positioning and replacement of the new fiber dressing can be completed. After the new fiber dressing is replaced, the inner adhesive layer 104, the sweat-absorbing cotton ring 105, and the antibacterial cotton ring 106 can also be used to protect the quick-tear part 101 on the outside to prevent the invasion of external liquids and bacteria.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
