Description

Hydrogel dressing

Technical Field

The utility model belongs to the technical field of medical dressing, and particularly relates to a hydrogel dressing.

Background

The dressing in the prior art generally comprises a gluing backing layer, a dressing core and a protective layer, however, the dressing core is generally of a single-layer structure of hydrogel, after the dressing is applied to a wound, the dressing is fixed on the wound through the gluing backing layer, and the dressing is not easy to tear off from the skin due to the fact that the gluing backing layer is high in adhesion degree with the skin, and meanwhile, the dressing is easy to pull to the wound, secondary damage is caused to the wound, and therefore the dressing is inconvenient to replace.

Disclosure of Invention

The utility model aims to provide a hydrogel dressing.

The hydrogel dressing provided by the utility model comprises a backing layer (1), a hydrogel layer (2), a silica gel layer (3) and a protective layer (4); one side of the hydrogel layer (2) is attached to the backing layer (1); one side of the silica gel layer (3) is attached to one side of the hydrogel layer (2) away from the backing layer (1); one side of the protective layer (4) is attached to one side of the silica gel layer (3) away from the hydrogel layer (2).

Preferably, the size of the silicone gel layer (3) is the same as the size of the backing layer (1).

Preferably, the size of the silicone gel layer (3) is larger than the size of the hydrogel layer (2).

Preferably, the silica gel layer (3) is uniformly provided with liquid suction holes (5).

Preferably, the hydrogel layer (2) is uniformly provided with ventilation holes (6).

The hydrogel dressing provided by the utility model has the advantages compared with the prior art:

1. by adding a layer of silica gel layer, the dressing can be easily torn off from the wound, and the dressing can be conveniently replaced;

2. when the dressing is torn off, the dressing cannot be torn to a wound, so that secondary injury to the wound cannot be caused;

3. punching the silica gel layer and the hydrogel layer to ensure that the liquid suction effect is faster, the air permeability is better, and the wound healing is facilitated;

4. the wound condition can be observed through the transparent backing layer without uncovering the dressing, thereby facilitating the observation of the wound condition.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The hydrogel dressing provided by the embodiment comprises a backing layer 1, a hydrogel layer 2, a silica gel layer 3 and a protective layer 4; one side of the hydrogel layer 2 is attached to the backing layer 1; one side of the silicone gel layer 3 is attached to one side of the hydrogel layer 2 away from the backing layer 1; one side of the protective layer 4 is attached to the side of the silicone gel layer 3 remote from the hydrogel layer 2. It can be appreciated by those skilled in the art that the hydrogel dressing provided in this embodiment is used, after the protective layer 4 is torn off, the silicone gel layer 3 is attached to the wound, when the silicone gel layer 3 is attached to the skin, the hydrogel dressing provided in this embodiment can be prevented from being adhered to the skin too firmly by the silicone gel layer 3, so that the dressing can be easily torn off from the skin, the dressing can be conveniently replaced, the wound is not involved when the dressing is torn off, and secondary damage to the wound can not be caused. Those skilled in the art will appreciate that the protective layer may be formed using a release paper or a release film.

Further, the size of the silicone gel layer 3 is the same as the size of the backing layer 1. It will be appreciated by those skilled in the art that the dimensions of the silicone gel layer 3 are the same as the dimensions of the backing layer 1, preventing the adhesive applied to the backing layer 1 from directly contacting the skin, only through the silicone gel layer 3.

Further, the size of the silicone gel layer 3 is larger than the size of the hydrogel layer 2. It will be appreciated by those skilled in the art that the hydrogel will have a reduced viscosity after imbibition and will readily release from the dressing, and this embodiment prevents this by adhering the hydrogel layer 2 therein via the silicone gel layer 3 and backing layer.

Further, the silicone gel layer 3 is uniformly provided with liquid suction holes 5. It will be appreciated by those skilled in the art that wound exudate can be rapidly absorbed by the hydrogel through the wicking aperture 5 in the silicone gel layer 3. Those skilled in the art will appreciate that the silicone layer 3 may be perforated using ultrasound.

Further, the hydrogel layer 2 is uniformly provided with ventilation holes 6. As will be appreciated by those skilled in the art, the ventilation holes 6 increase the surface area of the hydrogel on the one hand, thereby increasing the contact area with wound exudate and thus further increasing the wicking effect; on the other hand, through the communication of the ventilation holes 6 and the liquid suction holes 5, the ventilation property of the hydrogel dressing provided by the embodiment is improved, so that the healing of wounds can be quickened. As can be appreciated by those skilled in the art, hydrogels are characterized by a clear, refreshing feel with texture similar to human tissue, and a better comfort. Those skilled in the art will appreciate that the hydrogel layer 2 may be laser perforated to solve the problem of difficult perforation by conventional die cutting.

It will be appreciated by those skilled in the art that the backing layer 1 may also be made of a transparent material, so that the skin condition can be directly observed without tearing the dressing off.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
