When the porous pad 36 is arranged, the tip 27 (a) of the suction wound tube 26 (a) and the tip 27 (b) of the supply wound tube 26 (b) pierce the porous pad 36 from above. The tips 27 (a) and 27 (b) are inserted to the vicinity of the wound surface 32. When the work of piercing the wound tube 26 into the porous pad is performed at a place other than the wound portion 32 and the porous pad 36 into which the wound tube 26 is pierced is disposed on the wound portion 32, the wound portion 32 is also stimulated. More preferred.

  Next, the connection connector 24 is disposed on the central portion of the porous pad 36. The connection connector 24 may be disposed on the skin 84 in the vicinity of the wound portion 32, but is more compact when disposed on the porous pad 36. Thereafter, the suction wound portion tube 26 (a) and the supply wound portion tube 26 (b) are bent, and the other end of the suction wound portion tube 26 (a) is connected to the suction side connection port 12 (a) of the connection connector 24.

However, the suction wound tube 26 (a) and The connection of the supply wound tube 26 (b) to the suction side connection port 12 (a) and the supply side connection port 12 (b) of the wound tube 26 (a) and 26 (b) within the porous pad 36. By embedding the tips 27 (a) and 27 (b), the lengths of the wound tube 26 (a) and 26 (b) can be appropriately adjusted (cut) and then connected. For this reason, the shape of the side connection port 12 is preferably a shape that can be connected by inserting the wound tube 26.

  Next, the covering sheet 30 is covered on the skin 84, the wound portion 32, the porous pad 36, the connection connector 24, the suction wound portion tube 26 (a), and the supply wound portion tube 26 (b). The adhesive layer on the back surface of is adhered and fixed to the skin 84 and the sealing surface 22. At this time, since the shape of the opening hole 28 of the covering sheet 30 and the convex portion 46 of the connection connector 24 is substantially the same shape, positioning is easy, and there is no protrusion around the convex portion 46 of the connection connector 24. It can be easily coated with the coating sheet 30. Thereby, the closed portion 34 covering the wound portion 32 with the covering sheet 30 is formed, and the external connection ports 16 and 43 provided in the convex portion 46 of the connection connector 24 are disposed outside the closed portion 34. . Note that the covering sheet 30 may be prepared according to the size and shape of the wound part 32 even if various sizes and shapes are prepared in advance.

  One end of the suction external tube 48 (a) is connected to the connection connector 56 in advance to the suction external tube connection port 52 (a) of the connection connector 56, and one end of the supply external tube 48 (b) is connected to the connection connector 56. The pressure external tube 49 is connected in advance to the supply external tube connection port 52 (b), and one end of the pressure external tube 49 is connected to the pressure external tube connection port 78 of the connection connector 56 in advance.
