Abstract

curativo para produzir ambiente de baixo teor de oxigênio. a presente invenção refere-se a: curativo que inclui uma cobertura do local de aplicação e um eliminador de oxigênio, fornecido com ou posicionado em relação à cobertura do local de aplicação, de modo a remover o oxigênio de um volume abaixo da cobertura do local de aplicação e em torno de um local de aplicação coberto pela cobertura do local de aplicação; e artigo embalado. a cobertura do local de aplicação e o eliminador de oxigênio são configurados para manter a pressão do gás abaixo da cobertura do local de aplicação em torno do local de aplicação que está acima de uma pressão negativa terapêutica, enquanto o eliminador de oxigênio está consumindo oxigênio abaixo da cobertura do local de aplicação.
