Abstract

Un appareil d'élimination des excréments offre une force nécessaire à l'aspiration des déchets sans recourir à une pompe d'aspiration de grande taille. Une ventouse (2), conçue pour s'appliquer étroitement a l'entrejambe, est dotée d'une buse qui projette une eau de lavage vers l'entrejambe, d'un réservoir (23) placé dans le bas de la ventouse, et d'un orifice d'aspiration de déchets communiquant avec un orifice inférieur de communication du réservoir et aboutissant à un niveau prédéterminé. Une soupape d'ouverture et de fermeture s'ouvre avant l'utilistion de l'appareil pour laisser passer l'eau de lavage d'un réservoir (7) d'eau de lavage vers le réservoir (23) au travers d'une buse pour fermer l'orifice inférieur de communication. Un robinet à manchon (41) s'ouvre après l'utilisation pour que les déchets, contenus dans le réservoir (23) et constitués d'eau de lavage et d'excréments, soient aspirés d'un seul coup depuis l'orifice d'aspiration de déchets vers un réservoir à déchets (5) au travers d'une conduite pour déchets (3).
