Detailed Description

The present application is described in further detail below in conjunction with figures 1-6.

The embodiment of the application discloses a waterproof breathable application. Referring to fig. 1 and 2, including medicine layer 1, ventilative layer 2 and waterproof layer 3, medicine layer 1, ventilative layer 2 and waterproof layer 3 are closely adhered together, and when using the application, medicine layer 1 is located and is close to skin one side, and medicine layer 1 can the butt in skin and closely laminate with skin, ventilative layer 2 is located medicine layer 1 and keeps away from skin one side, and waterproof layer 3 is located ventilative layer 2 and keeps away from one side of skin. The air permeable layer 2 has the same area as the medicine layer 1, and the medicine layer 1 and the air permeable layer 2 are non-woven fabrics, and can be made of polyester fiber, polyester fiber and other materials by needling. The waterproof layer 3 stretches out ventilative layer 2 and medicine layer 1 setting all around, and waterproof layer 3 is provided with the pasting portion 33, and pasting portion 33 is located waterproof layer 3 and stretches out ventilative layer 2 and medicine layer 1 all around the part, and pasting portion 33 is pasted and is had the non-setting adhesive, can paste the application on skin.

Referring to fig. 2 and 3, the medicine layer 1 is a layer attached to the skin, the absorbent cotton 11 is stuck to the middle position of the medicine layer 1, the absorbent cotton 11 is in a circular shape, ointment is smeared on the absorbent cotton 11, the absorbent sponge 12 is stuck to the position of the medicine layer 1 corresponding to the absorbent cotton 11, the absorbent sponge 12 is positioned on one side of the absorbent cotton 11 far away from the skin, the absorbent sponge 12 can absorb pollutants such as dust in the air, and when the pollutants enter from the third ventilation holes 31, the pollutants are absorbed by the absorbent sponge 12 through the second ventilation holes 22, and meanwhile, the absorbent sponge 12 has certain ventilation property, the pollutants are prevented from contacting the absorbent cotton 11 while ventilation property is guaranteed, and the probability that the absorbent cotton 11 is polluted is reduced. The medicine layer 1 corresponds cotton wool 11 rectangle region all around and is provided with ventilative district 13, and ventilative district 13 area account for the third of medicine layer 1 area, and ventilative district 13 is provided with a plurality of bleeder vents 14, and first bleeder vent 14 is along medicine layer 1 length and width direction array setting, and the part outside medicine layer 1 corresponds ventilative district 13 is pasted and is had hydrogel 15, and hydrogel 15 can be mild paste in skin, plays certain fixed action, and in addition, hydrogel 15 is soft cool, is favorable to reinforcing the travelling comfort of applying.

Referring to fig. 2 and 4, a moisture detection test paper 21 is fixedly connected to one side, far away from the drug layer 1, of the ventilation layer 2, a plurality of second ventilation holes 22 are commonly formed in the positions, corresponding to the ventilation areas 13, of the ventilation layer 2 and the moisture detection test paper 21, the second ventilation holes 22 are arranged in an array along the length width direction of the ventilation layer 2, and the second ventilation holes 22 are all communicated with the first ventilation holes 14.

Referring to fig. 5 and 6, the waterproof layer 3 is made of a polyethylene composite transparent film, which is favorable for observing the change of the moisture detection test paper 21, the waterproof layer 3 is transparent, the color change of the moisture detection test paper 21 can be clearly observed, a plurality of third air holes 31 are arranged at the positions of the waterproof layer 3 corresponding to the second air holes 22, the third air holes 31 are communicated with the second air holes 22 and the first air holes 14, pre-crosslinked particles 32 are fixedly connected in the waterproof layer 3 corresponding to each third air hole 31, the pre-crosslinked particles 32 are particle-type gel which is formed by processing through the processes of drying, granulating, screening and the like after complex chemical reaction, and are provided with carboxyl, amide groups and the like, so that the gel is a high molecular water-absorbing resin which has a pre-crosslinked polymer network structure and can absorb water and expand. When the application encounters water, the pre-crosslinked particles 32 positioned in the third air holes 31 absorb water and expand, so that the corresponding third air holes 31 and second air holes 22 can be blocked, the channels for water to enter the medicine layer 1 are blocked by the third air holes 31 and the second air holes 22, the waterproof effect is achieved, and the application has air permeability and waterproof property. When the waterproof property of the application is lost, the moisture detection test paper 21 has a color change reaction, so that the medicine on the absorbent cotton 11 may be lost, and the application needs to be replaced.

Referring to fig. 2 and 5, a buffer part 35 is disposed at the position of the adhesive part 33 near the periphery of the breathable layer 2 and the drug layer 1, a plurality of fourth ventilation holes 34 are disposed at the position of the adhesive part 33 far away from the periphery of the breathable layer 2 and the drug layer 1, and when in use, the adhesive part 33 is adhered to the skin surface to be matched with the hydrogel 15 of the drug layer 1 to realize fixation of application, and the fourth ventilation holes 34 can keep good ventilation performance at the position of the adhesive part 33, so that the probability of red itching of skin is reduced. When water enters from the fourth ventilation holes 34, the buffer portion 35 can block the water from entering the medicine layer 1, and plays a role in protecting the medicine layer 1. The tearing piece 36 is arranged at one side of the waterproof layer 3 in the length direction and corresponds to the position of the pasting part 33, so that the pasting part is convenient to tear off after the use or after the medicine layer 1 fails, and the situation that the pasting part 33 is too tightly adhered to the skin and is not easy to tear off is improved.

The implementation principle of the waterproof breathable application is as follows: under normal conditions, the third air holes 31, the second air holes 22 and the first air holes 14 are mutually communicated, so that the application can keep good air permeability, when the application encounters water, the pre-crosslinked particles 32 of the waterproof layer 3 can expand rapidly after encountering water, the corresponding third air holes 31 and the second air holes 22 are blocked, the waterproof effect is achieved, and the condition that the medicine layer 1 encounters water to cause the medicine to lose efficacy is improved. Because waterproof layer 3 is transparent material, we can clearly observe the change of moisture test paper 21, when we observe that moisture test paper 21 discolours the back, just can learn the waterproof nature inefficacy of applying ointment or plaster, and absorbent cotton 11 high probability loses the drug effect, then needs to change new application at this moment.

The embodiment of the application has the effect of improving the application and simultaneously considering the air permeability and the water resistance.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
