Description

Technical Field

[0001] The utility model relates to the technical field of hydrophilic dressings, in particular to a hydrophilic dressing for absorbing exudate. Background Art

[0002] Hydrophilic fiber dressing is a new type of medical dressing, which is composed of hydrophilic fiber and other auxiliary materials. The main component of hydrophilic fiber dressing is hydrophilic fiber, which can quickly absorb the liquid exuded from the wound, keep the wound moist, and avoid dryness and adhesion of the wound. Hydrophilic fiber dressing also has good air permeability, which can prevent wound fluid accumulation and is conducive to wound healing. In addition, hydrophilic fiber dressing can also remove wound secretions and bacteria, keep the wound clean, and reduce the risk of infection. Hydrophilic fiber dressing has the characteristics of softness, which is very comfortable to apply on the wound and can relieve pain. Hydrophilic fiber dressing is easy to operate and can be directly applied on the wound without special equipment and skills. Hydrophilic fiber dressing is a very safe and effective medical dressing, which is widely used in wound dressing, surgical wound dressing and other occasions, and is of great significance to improving wound healing effect and reducing complications.

[0003] The hydrophilic dressing currently used on the market is shown in the patent of prior art publication number CN215229233U. By dividing the entire dressing layer into two, the two dressing layers can be freely separated and interlocked with each other, which can be more convenient to use on the wound with a catheter; the dressing core three composed of the dressing filled with silver ions at the bottom can play an antibacterial and anti-infection role on the wound, and at the same time, a guide hole 2 is also opened in the middle of the dressing core three, which can guide the permeate of the wound into the dressing core 2 filled with alginate dressing. The alginate dressing can absorb a large amount of exudate precipitated from the wound. After the exudate contacts with alginate, it expands to form a soft hydrogel. The volume of the expanded sheet is also small, and it will not cause a closed and airtight situation. A guide hole 1 is also opened in the middle of the dressing core 2, which can guide the excess permeate in the dressing core 2 into the dressing core 1 filled with polyurethane foam, further improving the adsorption effect of the permeate, reducing the number of dressing changes, and reducing the risk of wound infection.

[0004] However, the above dressing needs to be pressed against the wound when in use, and the dressing will stick to the wound after absorbing the exudate, which may cause discomfort at the wound and affect the air permeability of the skin at the wound. Utility Model Content
