Description
Technical Field
The utility model relates to the technical field of medical article, concretely relates to medical multilayer dressing.
Background
Medical dressings are wound covering articles used to cover sores, wounds, or other damaged medical materials. With the intensive research on the pathophysiology of the wound healing process, people understand the wound healing process more and more deeply, thereby leading to the continuous improvement and development of medical wound dressings. Today, the new dressing for wound care has revolutionized over the earlier days, and a variety of medical dressings with different properties are available for clinical care personnel to choose from.
In operations such as abscess excision drainage, postoperative incision sepage is more, and in current dressing, do not have an effective dressing special to the sepage is more, and dressing absorptive capacity is relatively poor, needs often to change, and medical personnel also only rely on the experience to change, lead to the wound to infect easily.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect among the prior art, provide a medical multilayer dressing, have and absorb a large amount of sepage, preserve the wound dry and comfortable, the suggestion of discolouing is renewed the dressing, prevents that the sepage from oozing the clothes function of making dirty outward.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a medical multilayer dressing, includes that the inner face absorbs water the layer, discolours and indicates layer and ventilative waterproof layer, the inner face absorbs water the layer, discolours and indicates layer and ventilative waterproof layer from interior to setting gradually outward, the inner face absorbs water the relative and overlapping setting of area on layer and the indication layer that discolours, the length and the width of ventilative waterproof layer all are greater than the inner face and absorb water the layer and discolour the length and the width on indication layer, the inner face absorbs water the layer and discolours the indication layer and sets up in the intermediate position of ventilative waterproof layer, the border position department all around of ventilative waterproof layer internal surface is provided.
In order to further realize the utility model, the inner surface water absorption layer comprises an inner pure cotton cloth layer and an outer fluff pulp layer.
In order to further realize the utility model discloses, the color-changing indicating layer includes gauze and fills the color-changing silica gel in the gauze.
In order to further realize the utility model discloses, ventilative waterproof layer is the waterproof ventilated membrane of transparent TPU.
Advantageous effects
The utility model is provided with the inner surface water absorption layer, which can effectively absorb a large amount of seepage and preserve the dryness of the wound; by arranging the color-changing indicating layer, the color of the color-changing indicating layer changes after moisture absorption, and when more seepage is absorbed by the inner surface water absorption layer, the dressing needs to be replaced at the moment; through setting up ventilative waterproof layer, can prevent that the sepage from oozing and making dirty clothes, less bacterium invades from the outside to a certain extent simultaneously.

Fig. 1 is a front view of the present invention;
fig. 2 is a bottom view of the present invention;
FIG. 3 is a cross-sectional view of the inner surface water-absorbing layer of the present invention;
fig. 4 is the schematic view of the internal structure of the color-changing indicating layer of the present invention.
Description of reference numerals:
1. an inner water-absorbing layer; 11. a pure cotton cloth layer; 12. a fluff pulp layer; 2. a color changing indicator layer; 21. gauze; 22. allochroic silica gel; 3. a breathable waterproof layer; 31. and 4, non-sticking.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention.
Example one
As shown in fig. 1-4, the medical multilayer dressing of the present invention comprises an inner surface water-absorbing layer 1, a color-changing indicating layer 2 and a breathable waterproof layer 3, wherein:
the inner surface water absorption layer 1, the color change indication layer 2 and the breathable waterproof layer 3 are sequentially adhered and fixed by glue from inside to outside.
The area that the inner face absorbed water layer 1 and discoloured indication layer 2 is relative and overlap the setting, the length and the width of ventilative waterproof layer 3 all are greater than the length and the width that the inner face absorbed water layer 1 and discoloured indication layer 2, the inner face absorbed water layer 1 and discoloured indication layer 2 and set up in ventilative waterproof layer 3's intermediate position, the edge position department all around of 3 internal surfaces of ventilative waterproof layer is provided with non-viscose 31, directly paste in skin, it is fixed firm, adopt non-viscose's setting, it is more convenient to use and change.
The inner surface water absorption layer 1 comprises an inner pure cotton cloth layer 11 and an outer fluff pulp layer 12, the pure cotton cloth layer 11 and the fluff pulp layer 12 are fixed through glue in an adhesion mode, and the inner side is the side contacting with the skin. The fluff pulp layer 12 has a strong water absorption function, and the pure cotton cloth layer 11 is in direct contact with the skin, so that the stimulation to the skin can be reduced.
The color-changing indication layer 2 comprises gauze 21 and color-changing silica gel 22 filled in the gauze 21, the primary color of the color-changing silica gel 22 is blue, the color of the color-changing silica gel is changed from blue to red after moisture absorption, and the inner surface of the color-changing silica gel absorbs more seepage absorbed by the layer 1 at the moment, so that the dressing needs to be replaced newly.
The breathable waterproof layer 3 is a transparent TPU waterproof breathable film.
In the embodiment, the inner surface water absorption layer is arranged, so that a large amount of seepage can be effectively absorbed, and the wound is kept dry and comfortable; by arranging the color-changing indicating layer, the color of the color-changing indicating layer changes after moisture absorption, and when more seepage is absorbed by the inner surface water absorption layer, the dressing needs to be replaced at the moment; through setting up ventilative waterproof layer, can prevent that the sepage from oozing and making dirty clothes, less bacterium invades from the outside to a certain extent simultaneously.
The above is only the preferred embodiment of the present invention, the present invention is not limited to the above embodiment, there may be local minor structural modification in the implementation process, if it is right that various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, and belong to the claims and the equivalent technical scope of the present invention, then the present invention is also intended to include these modifications and variations.
