The embodiment of the application discloses a minimally invasive surgery adhesive bandage convenient to replace. Referring to fig. 1, the wound covering includes a first covering layer 1, a second covering layer 2 and a water-absorbing pad 3.

The first adhesive layer 1 is in a circular or rectangular structure, a first adhesive layer (not shown in the attached drawing) is arranged on one side of the first adhesive layer 1 and used for being attached to the skin of a human body, a through hole 11 used for exposing a wound is formed in the middle of the first adhesive layer 1, and the shape of the through hole 11 is the same as that of the outer edge of the first adhesive layer 1.

For example, the wound on the human body is in a long strip shape, that is, the first adhesive layer 1 in a rectangular structure can be attached to the skin around the long strip wound, so that the wound is completely exposed from the through hole 11 in the same rectangular structure, and the exposed wound is conveniently applied with medicine through the water absorption pad 3. For example, the wound left by minimally invasive surgery is L-shaped. The first adhesive layer 1 in a circular structure can be attached to the skin around the wound so as to enable the wound to be completely exposed from the circular through hole 11, and meanwhile, the application area is reduced, and the treatment efficiency of the wound is improved.

The side of the second adhesive layer 2 facing the first adhesive layer 1 is provided with a second adhesive layer (not shown in the figure) for adhering to the first adhesive layer 1. The shape of the second adhesive layer 2 is the same as that of the first adhesive layer 1, and the area of the second adhesive layer is larger than that of the through hole 11 and smaller than that of the first adhesive layer 1.

The absorbent pad 3 is adsorbed with medicament, is attached to the through hole 11 of the first adhesive layer 1 and is abutted against the skin at the wound for applying the medicament to the wound.

Referring to fig. 2, in one embodiment, the absorbent pad 3 is fixed to the middle portion of the second layer 2, and when the second layer 2 is adhered to the first layer 1, the absorbent pad 3 is aligned with the through hole 11 of the first layer 1, so as to treat the wound on the human body at the through hole 11.

In another implementation, the absorbent pad 3 is an independent body, the absorbent pad 3 adsorbed with the medicament is adhered to the corresponding position of the second adhesive layer 2, and then the second adhesive layer 2 is adhered to the first adhesive layer 1, so that the absorbent pad 3 is fixed; or the water absorption pad 3 is directly laid at the through hole 11, and the second adhesive layer 2 is adhered on the first adhesive layer 1 to fix the water absorption pad 3.

Wherein, the viscosity of the second glue film on the second subsides layer 2 is less than the viscosity of first glue film, and the patient can take off the second subsides layer 2 from first subsides layer 1 easily when changing the adhesive bandage, can make first subsides layer 1 bear the pulling force this moment, prevents that the wound from being pulled open or causing the sense of pain, can take off the water absorption pad 3 jointly after the second subsides layer 2 is taken off, places new water absorption pad 3 in wound skin department and covers new water absorption pad 3 fixed once more through second subsides layer 2.

The water absorption pad 3 is liquid or paste, and comprises 20-35% of cephalosporin, 20-35% of penicillin, 15-20% of pseudo-ginseng, 10-15% of collagen peptide and 3-5% of other ointment auxiliary materials. Wherein, the other ointment adjuvants comprise one or more of epidermal growth factor, medical chitosan, healing new liquid and vaseline for promoting wound tissue repair, accelerating granulation growth and cell proliferation, or reducing infection risk; the components of the cephalosporin and the penicillin in the medicament can sterilize wounds and inhibit bacterial reproduction; the Notoginseng radix has effects of stopping bleeding, removing blood stasis, relieving pain and promoting blood circulation; the collagen peptide can repair the skin at the wound, keep the skin around the wound moist and healthy and is beneficial to the healing of the wound.

Referring to fig. 1, the side of the first adhesive layer 1 deviating from the first adhesive layer and the side of the second adhesive layer 2 deviating from the second adhesive layer are both provided with hydrophobic layers 4 for preventing the outside water flow from soaking and washing the water absorption pad 3, reducing the dilution of the medicament in the water absorption pad 3, and simultaneously preventing the outside water flow from infecting the wound.

The picture 21 that can be customized deviates from the side of second glue film at second adhesion layer 2, picture 21 can be drawn between hydrophobic layer 4 and second adhesion layer 2, can make the hydrophobic layer 4 on second adhesion layer 2 form the protective layer to picture 21 to reduce external environment and cause to stain picture 21 and produce and lose color or the phenomenon of cross color, for example bloodstain, oil stain, wash water etc.. Doctors and patients can have better mood when seeing interesting pictures 21 or comics with good connotation, which is beneficial to improving doctor-patient relationship and simultaneously improving the condition of the patient.

First subsides layer 1, second subsides layer 2 and absorbent pad 3 are independent each other, can go on packing each part alone after production is accomplished to the patient uses absorbent pad 3 of individual package when regularly changing dressings, reduces the waste to other not change parts. Meanwhile, the patient can replace the second pasting layer 2 with different patterns at any time according to the own favor of different patterns on the second pasting layer 2, so that the richness of pattern display can be improved.

Further, referring to fig. 2 and 3, the thickness of the inner edge of the first adhesive layer 1 is greater than the thickness of the outer edge, that is, the side of the first adhesive layer 1 departing from the first adhesive layer is an inclined plane, and the other side is a plane, so that the first adhesive layer 1 is completely attached to the skin of a human body, and the water absorption pad 3 arranged in the through hole 11 is shielded, thereby preventing the water absorption pad 3 from being displaced under the action force of external force such as touch. Therefore, the through hole 11 in the middle of the first adhesive layer 1 can form a clamping groove for accommodating the water absorption pad 3, so that the water absorption pad 3 is more convenient to replace, and the position is accurate.

In addition, the thickness of the inner edge of the first adhesive layer 1 is not more than that of the absorbent pad 3, so that the second adhesive layer 2 can be tightly attached to the absorbent pad 3, the absorbent pad 3 can be tightly attached to the wound of the skin, and the medicine in the absorbent pad 3 can be fully acted on the wound. In the embodiment, the thickness of the inner edge of the first adhesive layer 1 is 0.3mm, the thickness of the water absorption pad 3 is 0.4-1.0 mm, and the influence on the normal life of the patient can be reduced to the maximum extent due to the thinner thickness.

Further, referring to fig. 3, at least one diversion trench 5 is opened towards the side of the first glue layer on the first adhesive layer 1, and the inner wall of the diversion trench 5 can be the first adhesive layer 1 body, and also can be an arc-shaped plate fixedly connected to the lower side surface of the first adhesive layer 1, that is, the first adhesive layer 1 is fixedly bonded to the upper surface of the arc-shaped plate.
