Summary: | PROBLEM TO BE SOLVED: To mitigate heat and moisture build-up of negative pressure respirators.SOLUTION: The present invention relates to an exhaust apparatus 10 for releasable or permanent connection to a personal protection respiratory device 20 that defines a filtered air volume adjacent to the face of a wearer 100 and comprises at least one exhalation valve. The exhaust apparatus 10 comprising a powered blower in fluid connection with the at least one exhalation valve, the powered blower being operable to draw a portion of exhaled breath of the wearer 100 through the at least one exhalation valve. Using such an exhaust apparatus 10 for releasable connection to a personal protection respiratory device 20 improves the comfort and overall experience for respirator wearers who use the respirator for intensive work, and/or for long periods of time, and/or in hot and humid environmental conditions, by removing the heat and moisture build-up inside the respirator.SELECTED DRAWING: Figure 1
【課題】負圧呼吸器の熱、湿気の蓄積を改善する。【解決手段】着用者100の顔に隣接して濾過空気容量部を画定するとともに少なくとも1つの呼気弁を備える個人保護呼吸デバイス20に解放可能に又は恒久的に接続する排気装置10に関する。排気装置10は、少なくとも1つの呼気弁と流体接続する電動送風機を備え、この電動送風機は、少なくとも1つの呼気弁を通って着用者100の呼気の一部を引き出すように動作可能である。個人保護呼吸デバイス20に解放可能に接続するために係る排気装置10を使用することは、呼吸器内に蓄積された熱及び湿気を除去することによって、激しい労働下で、及び/又は長期間、及び/又は高温多湿の環境条件下で呼吸器を使用する呼吸器着用者の快適さ及び全体的な体験を向上させる。【選択図】図1 |
