[0026] Embodiment 1

[0027] An embodiment of the present utility model discloses a navel patch. As Figure 2 shown, the navel patch includes a backing cloth layer 1. An adhesive is evenly coated on the inner side of the backing cloth layer 1 to form an adhesive layer 5. An isolation ring 7 is pasted at the central part of the adhesive layer 5. The inside of the isolation ring 7 is the placement area of the medicament layer 6. The medicament layer 6 can be in the form of an ointment, a pill, etc. The medicament layer 6 is fixedly bonded to the adhesive layer 5 through the adhesive. An isolation layer 8 is covered above the medicament layer 6. The material of the isolation layer 8 is gauze or other permeable membrane materials. The area of the isolation layer 8 is smaller than the area of the adhesive layer 5 and larger than the area of the isolation ring 7. It is fixedly bonded to the adhesive layer 5 through the adhesive. The shape of the isolation layer 8 is circular or the same as the shape of the adhesive layer 5. The edge of the isolation layer 8 is 2 cm or 3 cm away from the edge of the adhesive layer 5. The 2 - 3 cm of the adhesive exposed at the edge of the adhesive layer 5 is used to bond the protective layer 9 and is adhered to the skin of the patient during use. A protective layer 9 is covered above the isolation layer 8. The protective layer 9 is bonded to the adhesive layer 5 through the adhesive. The two sides of the navel patch are serrated edges 3, which are convenient for the patient to peel off the protective layer 9 during use.

[0028] As Figure 1 and 3 shown, a sealing film 2 is provided on the outer side of the backing cloth layer 1. The sealing film 2 is a closed structure, and a closed space 21 is formed in the middle. A cleaning cotton pad 4 is placed in the closed space 21. The cleaning cotton pad 4 can be an alcohol cotton pad, an ordinary wet wipe or a cotton pad soaked with other solvents.

After a certain period of time, remove the navel patch. Before removing the patch, the sealing film 2 can be first opened with the hand to take out the cleaning cotton pad 4, and then the patch is removed. After removing the patch, there will be some ointment remaining on the skin, which can be wiped clean with the cleaning cotton pad 4. This eliminates the need for the patient to find a towel or a wet wipe again.
