In the high tension creation cladding material, 1st fluid such as oxygen, the first fluid is conveyance possible with the fluid transmitted impossible formation which is transmission impossible and the 1st fluid the fluid transmitted possible formation which is transmission possible, the edge of fluid transmitted impossible formation and fluid transmitted possible formation is done the sealing together, to stop on the skin which surrounds the external wound of the patient it is possible the edge of the high tension creation cladding material. Because of this, when the 1st fluid is conveyed, the 1st fluid, passing by fluid transmitted possible formation, it can transmit in the high tension creation cladding material and inside the head clearance between the external wounds. Punch is formed because the 2nd fluid of external wound bleed and the like passes, through fluid transmitted possible formation and fluid transmitted impossible formation. As for at this punch, you open the occasion where pressure inside the head clearance between the external wound and the high tension creation cladding material exceeds established pressure, at the same time, as for aforementioned punch, the occasion where particular pressure is less than established pressure, you close.高圧創被覆材において、酸素等の第1流体が、第一流体が透過不能である流体透過不能層と、第1流体が透過可能である流体透過可能層との間で搬送可能であり、流体透過不能層及び流体透過可能層の縁部が共にシーリングされ、高圧創被覆材の縁部を患者の外傷を取り囲む皮膚に留めることができる。これにより、第1流体が搬送される時、第1流体が、流体透過可能層を通って高圧創被覆材と外傷の間の頭隙内に透過できる。外傷滲出液等の第2流体が通過するために、流体透過可能層及び流体透過不能層を通して穿孔が形成されている。この穿孔は、外傷と高圧創被覆材の間の頭隙内の圧力が既定の圧力を上回る際に開き、且つ、前記穿孔は、当該圧力が既定の圧力を下回る際に、閉じる。
