Abstract

La présente invention concerne un filtre d'élimination des fumées à couches multiples de type compact comprenant une feuille d'absorption d'humidité, un pré-filtre pour filtrer des particules et de la poussière, un filtre principal ayant une fonction hydrophobe, et une feuille de charbon actif, qui sont empilés les uns sur les autres. Le filtre d'élimination des fumées pour la chirurgie laparoscopique selon la présente invention élimine des gaz, qui sont nuisibles pour les corps humains, en protégeant ainsi la santé des patients et des médecins et en évitant la dégradation du champ de vision au cours de la chirurgie, qui pourrait sinon résulter d'une fumée générée.
