Title
(EN) AN ARTICLE OF PERSONAL PROTECTIVE EQUIPMENT WITH A PUMP
(FR) ARTICLE D'ÉQUIPEMENT DE PROTECTION PERSONNEL AVEC UNE POMPE
Abstract
(EN) An article of personal protective equipment (PPE) formed from a semipermeable arrangement, wherein the semipermeable arrangement comprises a self-cleaning means that is formed at least partially from polytetrafluoroethylene (PTFE) and which, in use, defines the exterior surface of the article of PPE. The self-cleaning means comprising a self-cleaning web and the semipermeable arrangement comprises a support means for supporting the self-cleaning web, the support means being a mesh fabric. The support means and the self-cleaning web are bound together via a binding means disposed between the self-cleaning web and the support means with gaps such that there are areas not covered by the binding means.
(FR) La présente invention concerne un article d'équipement de protection personnel (PPE) formé à partir d'un agencement semi-perméable, l'agencement semi-perméable comprenant un moyen d'auto-nettoyage qui est formé au moins partiellement à partir de polytétrafluoroéthylène (PTFE) et qui définit, lors de l'utilisation, la surface extérieure de l'article PPE. Le moyen d'auto-nettoyage comprend une bande auto-nettoyante et l'agencement semi-perméable comprend un moyen de support pour supporter la bande auto-nettoyante, le moyen de support étant un tissu maillé. Le moyen de support et la bande auto-nettoyante sont liés ensemble par l'intermédiaire d'un moyen de liaison disposé entre la bande auto-nettoyante et le moyen de support avec des espaces de telle sorte qu'il y a des zones non couvertes par le moyen de liaison.
