Title
(EN) SYRINGE-BASED MICROBUBBLE GENERATOR WITH AN AERATOR
(FR) GÉNÉRATEUR DE MICROBULLES À BASE DE SERINGUE À AÉRATEUR
Abstract
(EN) A device includes a syringe having a barrel and a syringe tip; an aerator having (i) a generally cylindrical exterior body; (ii) an inlet end; (iii) an outlet end; (iv) a tapered outlet port at its outlet end; and (v) an interior cavity comprising (A) an input port section, (B) a converging section, (C) a throat section, (D) a diverging section, (E) an outlet section, (F) a first vent that fluidly couples at least one of the throat section or the diverging section to an area outside and adjacent to the exterior body, and (G) a second vent that fluidly couples the outlet section to the area; and a housing that (x) circumferentially surrounds an end of the barrel and the aerator, (z) has an interior surface, (aa) forms a circumferential gas pocket between the interior surface and the exterior body, and (bb) has a housing discharge tip.
(FR) Un dispositif comprend une seringue ayant un cylindre et une pointe de seringue ; un aérateur ayant (i) un corps extérieur généralement cylindrique ; (ii) une extrémité d'entrée ; (iii) une extrémité de sortie ; (iv) un orifice de sortie conique au niveau de son extrémité de sortie ; et (v) une cavité intérieure comprenant (A) une section de port d'entrée, (B) une section convergente, (C) une section gorge, (D) une section divergente, (E) une section de sortie, (F) un premier évent qui met en communication fluidique au moins l'une de la section gorge ou la section divergente à une zone à l'extérieur du corps extérieur et adjacente à celui-ci, et (G) un second évent qui met en communication fluidique la section de sortie à la zone ; et un boîtier qui (x) entoure de manière circonférentielle une extrémité du cylindre et l'aérateur, (z) a une surface intérieure, (aa) forme une poche de gaz circonférentielle entre la surface intérieure et le corps extérieur, et (bb) a une pointe d'évacuation de boîtier.
