Detailed Description

The present utility model will be described in detail below with reference to the accompanying drawings and examples.

1-2, including non-woven fabrics basic unit 1, one side of non-woven fabrics basic unit 1 is provided with dressing layer 2, and the opposite side is provided with water-resistant layer 3, when human injury, with hemostatic drug spraying to the wound on, utilize dressing layer 2 that hollow polyester fiber made, contact with the wound to let dressing layer 2 intercept the medicine at the wound surface, avoid the medicine to drop or break away from the wound, cause the difficult condition of healing to appear of wound.

Simultaneously, as the dressing layer 2 is formed by adhering a plurality of strip belts 5 arranged along the length of the non-woven fabric base layer 1 to the surface of the non-woven fabric base layer 1, an air flowing channel is formed between the strip belts 5, so that air can exchange with outside air through the channel, the air can enter a wound, the wound can be healed better, the wound can be kept in a dry state due to the flowing of the air, bacterial breeding can be effectively avoided from occurring in the dry wound, and inflammation is avoided.

The waterproof layer 3 located at one end of the non-woven fabric base layer 1 far away from the dressing layer 2 can block liquid along the direction from the waterproof layer 3 to the dressing layer 2 through the excellent waterproof performance, so that the situation that the liquid directly passes through the bandage to contact with the wound to cause inflammation after the wound contacts with external liquid is avoided, the wound can heal better, and a wounded person can recover faster.

The effect of the water-resistant layer 3 can block bacteria in the course of air entering through the gaps formed between the strip strips 5, the strip strips 5 are in a raised state, the nap 8 extends into the gap area partially and forms a barrier, and the bacteria are difficult to enter the wound along the gaps between the strip strips 5, so that the wound infection is avoided.

Gaps are formed between the adjacent strip belts 5, a plurality of strip belts 5 are combined to form block belts, the block belts are composed of more than two strip belts 5, the gaps between the adjacent strip belts 5 can enable air to enter into the non-woven fabrics from the side edges of the non-woven fabrics, so that the ventilation effect of the non-woven fabrics when the non-woven fabrics are used for laying wounds is achieved, the defect that the non-woven fabrics are poor in ventilation is avoided, and the block belts formed by the combination of the strip belts 5 can enable the adjacent block belts to form intervals.

Be provided with water repellent strip 7 between the adjacent cubic area, water repellent strip 7 can follow strip area 5 along length direction setting to separate into a plurality of regions with the bandage, and when waterproof strip separates it, can utilize its better manger plate performance, make the liquid be difficult to flow between each region, thereby avoid the liquid to permeate to the wound along the width direction of bandage, and the condition that causes wound infection appears.

At this time, the product can block the liquid from the water-resistant layer 3 to the dressing layer 2 along the width direction, and the liquid in the length direction is not easy to transfer along the length direction because the distance required to be transferred in the length direction is longer, so that the water-proof treatment is not required.

As shown in fig. 3, nap 8 is formed on dressing layer 2 through napping, the surface of dressing layer 2 far away from non-woven fabric base layer 1 is provided with nap 8 by vacuum napping process, dressing layer 2 can have three-dimensional sense, one side of nap 8 of dressing layer 2 can also be paved with corresponding medicine powder, so that medicine powder can directly contact with wound through dressing layer 2, nap 8 of dressing layer 2 is wound with decomposition layer 9, decomposition layer 9 is made of a plurality of alginate fibers, decomposition layer 9 is spun and set on nap 8 by a plurality of alginate fiber filaments, yarns are fixed by different forms of each nap 8, decomposition layer 9 is set at nap 8 on dressing layer 2 when decomposition layer 9 is set, make the decomposition layer 9 can nest, fix on fine hair 8, when tearing down the bandage, because some alginate fibre can contact with the wound, cause the alginate fibre to adhere to the wound, the alginate fibre of pure winding on dressing layer 2 this moment is when tearing down, if receive the power of wound bonding great, can break away from with fine hair 8, leave the alginate fibre on the wound from, because the alginate fibre has the gel nature, can form one deck stable netted gel, avoid the wound flooding, build a microenvironment that does benefit to the tissue growth for the wound, promote wound healing, even it is left on the wound also can be decomposed by the human body, and can not exert an influence to the human body, its fine antibacterial effect simultaneously, can let the wound be difficult for breeding the bacterium.

The non-woven fabrics basic unit 1 and water repellent strip 7 adopt TPU to melt and spray to make, and the application of TPU material can also restrict the liquid conduction between dressing layer 2 when at utmost avoiding external water to enter into dressing layer 2, prevents that liquid from spreading along width direction between dressing layer 2, has reduced the infection risk that the non-woven fabrics caused the wound, water-resistant layer 3 adopts TPU water proof membrane, and water proof membrane's setting can block the liquid along water-resistant layer 3 to dressing layer 2 direction, avoids the area between dressing layer 2 and the wound to be wet, ensures the drying in wound area.

When the product is produced, water-soluble substances are used for separation between the strip belts 5, TPU melt is sprayed onto the strip belts 5 through melt spraying to form a non-woven fabric base layer 1 by utilizing a spinneret plate, so that the solidified TPU fibers of the strip belts 5 are adhered to achieve the effect of fixing the strip belts 5, meanwhile, at the strip belts 5 without the water-soluble substances, TPU fibers are directly sprayed between the strip belts 5 to form water repellent strips 7, then a TPU waterproof film is compounded onto the surfaces of the non-woven fabric base layer 1, then the strip belts 5 are napped through a napping process to form naps 8 on the surfaces of the strip belts 5, finally, the product is sent into a groove in which seaweed fibers are placed, then two ends in the length direction are fixed on a reciprocating machine, the reciprocating machine is utilized to make the naps 8 on the strip belts 5 contact with the seaweed fibers in a friction mode, the naps 8 and the seaweed fibers can be wound with each other in a winding mode during friction, and at the moment, the decomposition layer 9 can be fixed on the naps 8.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
