Technical Field
[0001] The utility model relates to the field of medical supplies technology and wound dressings, and in particular to a stretchable medical dressing with good wound adhesion. Background Art
[0002] Most existing medical dressings are made of non-elastic structural layers, including foamed polymer dressings, hydrocolloid dressings, alginate dressings, synthetic fiber dressings, and the earliest used natural gauze. These dressings often have poor wound adhesion during actual use. The reason is that when the dressing is used on special parts of the patient, such as joints, heels and other parts with a certain degree of curvature, the dressing cannot fit well with these parts, causing the dressing to be bent multiple times, resulting in the fixed part of the dressing being offset, presenting a bulge in the middle, which is not conducive to wound healing. In addition, after the drug components added to the dressing itself are absorbed, it is impossible to change the dressing in time through a simpler method that reduces the patient's pain.
[0003] Common medical dressings only have adhesive functions and can stick to human wounds, but lack the functions of stretchability and convenient dressing changes. There is no guarantee that the dressing can completely fit the wound and that it will not cause pain to the patient during dressing changes. It is easy for the dressing to not have a stretchable and rebound structure, resulting in poor adhesion to wounds in special areas. In addition, the dressing needs to be torn off the wound during dressing changes, which causes the skin at the wound to be pulled, causing pain to the patient.
[0004] Therefore, in view of the fact that the above-mentioned medical dressings lack the functions of stretchability and convenient dressing change, a stretchable medical dressing with good wound adhesion can be designed. By providing a core layer made by S-shaped pre-cutting method, the stretchability of the dressing is increased, the applicability is stronger, and it is easier to fit special parts such as joints, which is convenient for patients to move freely. The upper adhesive layer is torn off through the butterfly wings to separate the lower dressing from the upper dressing, and then the high-absorbency core dressing can be replaced, which is convenient for timely replacement of the medicine suitable for the wound.
