Abstract

L'invention concerne un ensemble de rééquipement de stérilisation destiné à des endoscopes comportant au moins un canal de transport (4, 7) d'air ou d'eau par exemple, aboutissant sur une extrémité de tête distale (1) de l'endoscope. Un tel ensemble de rééquipement de stérilisation comporte un élément de couverture (10) destiné à envelopper l'extrémité de tête distale (1) d'un endoscope. Ledit élément de couverture (10) comporte au moins une zone de passage de lumière transparente (15, 16, 19) située dans une surface frontale de couverture (11), chevauchant une zone de sortie de lumière (6a, 6b) et une zone optique (5) sur l'extrémité de tête (1) de l'endoscope. La surface frontale de couverture (11) comporte au moins une ouverture de passage (18) pourvue d'une pièce de connexion creuse (21) destinée à une pièce de conduite (32). Un tel ensemble de rééquipement de stérilisation comporte également une pièce de conduite pouvant être connectée à la pièce de connexion (21) et présentant une longueur correspondant au moins à la longueur de l'extrémité de tête distale (1) de l'endoscope à une zone de sortie proximale (71) du canal de transport (4) de l'endoscope. L'invention concerne également un procédé de stérilisation simple d'une partie (2, 3) de l'endoscope à introduire dans un corps, notamment un procédé de préparation d'un endoscope par exemple destiné à l'insémination artificielle d'un humain ou d'un animal tel qu'une jument, devant être maintenu stérile lors de l'intervention.
