Description
Technical Field
The application relates to the field of wound adhesives, in particular to a chitosan wound adhesive.
Background
At present, in daily work and life, the situation that fingers are scratched is avoided, people often wrap wounds with the adhesive bandage, and the probability of wound infection is reduced.
The common adhesive bandage is mainly in a strip shape and mainly comprises an adhesive cloth layer and a medicine layer, wherein the medicine layer is positioned at the middle position of the adhesive bandage in the length direction and the width direction, absorbent cotton is stuck at the position of the adhesive bandage corresponding to the medicine layer, and the adhesive cloth layer is positioned at the position of the adhesive bandage far away from the medicine layer. When the finger is scratched, the medicine layer of the adhesive bandage is aligned to the wound, and as the medicine layer has no adhesiveness and can be higher than other parts, dust and pollutants in the air easily enter from the position of the medicine layer corresponding to one side of the long side of the adhesive bandage, the medicine layer is polluted and even the wound is infected, the periphery of the medicine layer is covered by the adhesive bandage, so that the probability of the wound being infected is reduced.
For the related art, because of uncertainty of the wound, a long wound is drawn by a finger sometimes, the medicine layer of one adhesive bandage cannot cover all the wounds, meanwhile, because the medicine layer is covered with adhesive plaster layers all around, the adhesive plaster layers can interfere with each other when a plurality of adhesive plaster are pasted, the wound cannot be completely covered by the medicine layer, and recovery of the wound is not facilitated.
Disclosure of Invention
In order to improve the situation that a plurality of wound pastes are simultaneously used without interference when the wound is overlong along the length direction of the finger or overlong along the width direction of the finger and can completely cover the wound, the application provides a chitosan wound paste.
The chitosan band-aid provided by the application adopts the following technical scheme:
a chitosan wound dressing comprising:
the wound plaster body can be wound and fixed on a finger;
the medicine layer is arranged on one side of the adhesive bandage;
the first detachable part and the second detachable part are arranged at two sides of the corresponding medicine layer of the wound plaster body along the first direction;
the third detachable part and the fourth detachable part are arranged on two sides of the wound plaster body corresponding to the medicine layer along the second direction, the first detachable part, the second detachable part, the third detachable part and the fourth detachable part can be torn off, the first direction is perpendicular to the second direction, and the medicine layer is surrounded by the first detachable part, the second detachable part, the third detachable part and the fourth detachable part on the plane of the wound plaster body;

the second pasting part is arranged at two sides of the adhesive bandage body corresponding to the length direction of the first pasting part;
the third pasting part is arranged at two sides of the band-aid body corresponding to the width direction of the first pasting part.
By adopting the scheme, when the finger wound is overlong along the length direction of the finger, the first detachable part of one adhesive bandage can be torn off along the tearing line, then the release paper of the first adhesive part and the second adhesive part is torn off, the second detachable part of the second adhesive bandage is adhered to the positions of the first adhesive part and the second adhesive part of the first adhesive bandage, and the medicine layers of the two adhesive bandages can be arranged side by side along the width direction so as to cover the vertically overlong wound on the finger; when the finger wound is overlong along the finger width direction, the third detachable part of one adhesive bandage can be torn off along the tearing line, release paper of the first adhesive part and the third adhesive part is torn off, the third detachable part of the second adhesive bandage is adhered to the positions of the first adhesive part and the third adhesive part of the first adhesive bandage, and the medicine layers of the two adhesive bandages can be arranged side by side along the length direction so as to cover the wound transversely overlong on the finger. The situation that a plurality of adhesive tapes are used simultaneously without interference when the wound is overlong along the length direction of the finger or overlong along the width direction of the finger and the wound can be completely covered is improved.
Preferably, the positions of the adhesive bandage body corresponding to the four edges of the medicine layer are provided with tearing lines, and the tearing lines are prolonged along the length-width direction of the medicine layer.
Through adopting above-mentioned scheme, the user can tear first removable portion or second removable portion or third removable portion or fourth removable portion along tearing the line, has improved and has torn the untidy condition of drawing, can make two or even more wound tape body concatenation more neat.
Preferably, one end of the adhesive bandage body in the length direction is provided with an adhesive strip.
By adopting the scheme, after the wound plaster body is wound around the finger, the adhesive tape can be adhered to the wound plaster body to fix the wound plaster, so that the condition that the skin is injured when the adhesive tape is adhered to the finger skin is improved.
Preferably, the attachment strip is provided with a double layer.
Through adopting above-mentioned scheme, when the easy condition that leads to the fact the sticky note to paste inefficacy of sticky note because of friction and the pollution of dust in the air, the user can tear first layer sticky note, continues to paste through the second floor sticky note, reaches the effect of lasting sticking, reduces the probability that the adhesive bandage drops from the finger.
Preferably, the position of the wound plaster body corresponding to the medicine layer is provided with a ventilation sponge, and the ventilation sponge is stuck between the wound plaster body and the medicine layer.
Through adopting above-mentioned scheme, ventilative sponge can make the air get into, can also isolate the dust in the air outside the medicine layer simultaneously, still reduce the probability that the medicine layer was polluted when making the adhesive bandage keep good gas permeability.
Preferably, the wound plaster body is composed of chitosan nonwoven cloth with elasticity.
Through adopting above-mentioned scheme, when fixing the adhesive bandage body through unilateral sticky strip, adhesive bandage body and finger do not have direct adhesive contact, follow finger length direction landing easily, and elastic material can make the adhesive bandage body closely laminate the finger, reduces the adhesive bandage body and breaks away from the probability of finger.
Preferably, the position of the wound plaster body corresponding to the medicine layer is provided with a covering layer, the covering layer is arranged along the width direction of the wound plaster body, and the covering layer can be covered on the medicine layer and stuck on the wound plaster body.
