Title
(EN) ENDOSCOPE PROVIDED WITH A DEVICE FOR CLOSING A FLUID FLOW CIRCUIT, FOR IMPROVED STERILISATION
(FR) ENDOSCOPE POURVU D'UN DISPOSITIF D'OBTURATION D'UN CIRCUIT DE CIRCULATION D'UN FLUIDE, POUR UNE STERILISATION AMELIOREE
Abstract
(EN)
The invention relates to a medical endoscope comprising: - a piston barrel (17) in which a piston is movably mounted; - the piston together with the piston barrel (17) delimiting a sealed closure section and a sealed interconnection chamber designed so that in the open position of the closure device (11), the sealed interconnection chamber ensures communication between a first portion (101) and a second portion (102) of the flow circuit. According to the invention, the sealed interconnection chamber (40) comprises a hole (45) passing right through the piston (18) to open into a cylindrical chamber (46), and is delimited between the piston (18) and the piston barrel (17) by an oblong section located, in the open position of the flow circuit, opposite the inlet sections (21a, 22a) of the tubes (21, 22) for connection to the first portion and to the second portion of the flow circuit, in order to limit the pressure drop.

L'invention concerne un endoscope médical comportant : - un corps de piston (17) dans lequel un piston est monté mobile en déplacement; - le piston délimitant avec le corps de piston (17) une section étanche d'obturation et une chambre étanche d'interconnexion adaptées pour qu'en position d'ouverture du dispositif d'obturation (11), la chambre étanche d'interconnexion assure la communication entre une première portion (101) et une deuxième portion (102) du circuit de circulation. Selon l'invention, la chambre étanche d'interconnexion (40) comportant un trou (45) traversant de part en part le piston (18) pour déboucher dans une chambre cylindrique (46) délimitée entre le piston (18) et le corps de piston (17), par une section oblongue située en position d'ouverture du circuit de circulation, en face des sections d'entrée (21a, 22a) des tubulures (21, 22) de raccordement à la première portion et à la deuxième portion du circuit de circulation pour limiter la perte de charge.
