PROBLEM TO BE SOLVED: To provide a negative pressure wound treatment device including a pressure measuring tube in which exudate and suspended matters in the exudate do not easily get stuck.SOLUTION: A closed part is formed by covering a wound part 12 with a covering material 14 including a supply hole 15 and a discharge hole 17. A supply tube connection component 16 is connected to the supply hole 15, and a washing liquid supply tube 21 and a pressure measuring tube 27 are connected to the supply tube connection component 16. A discharge tube connection component 18 is connected to the discharge hole 17, and an exudate discharge tube 22 is connected to the discharge tube connection component 18. Washing liquid 20 is supplied to the closed part through the washing liquid supply tube 21. While keeping the closed part at a negative pressure, the washing liquid 20 and waste and exudate generated from the wound part 12 are sucked and discharged through the exudate discharge tube 22. The magnitude of the negative pressure is measured through the pressure measuring tube 27.COPYRIGHT: (C)2012,JPO&INPIT【課題】滲出液や滲出液内の浮遊物が詰まりにくい圧力測定管を備えた陰圧創傷治療装置を実現する。【解決手段】供給孔15と排出孔17を備えた被覆材14で創傷部12を覆って閉鎖部を形成する。供給管接続部品16を供給孔15に接続し、洗浄液供給管21および圧力測定管27を供給管接続部品16に接続する。排出管接続部品18を排出孔17に接続し、滲出液排出管22を排出管接続部品18に接続する。洗浄液20を洗浄液供給管21を通じて閉鎖部に供給する。閉鎖部を陰圧に保ちながら、洗浄液20と、創傷部12から生じた老廃物および滲出液を滲出液排出管22を通じて吸引排出する。陰圧の大きさを、圧力測定管27を通じて測定する。【選択図】図1
