1. Probe device for the channeling or draining of a biological fluid of the type made of a flexible material notably silicon elastomer and having : - one or several helical depressions or grooves (9 or 9a, 9b, 9c) with being provided in its outer surface and staggered with respect to one another in the lengthwise direction, separate turns (4a or 4b or 4'a, 4''a, 4'''a) belonging to one or several helical bulges of constant or variable pitch, and - possibly side openings (11) communicating with the outside of the device, said openings being arranged in said helical depressions or depression (9), and in paticular at the distal end, wherein said helical bulges, and before said turns (4a or 4b or 4'a, 4''a, 4'''a) are hollow, so that the turns intercommunicating with another, that is to say belonging to a same bulge, define or one several independant peripheral ducts (5a or 5b or 5'a, 5''a, 5'''a), each communicating, at the proximal extremity (14), with the opening of a side nozzle (13 or 13 a, 13 b) connected to a ventilation aperture and/or to irrigation or instillation liquid source, whereast at the distal end (12) at least one of said peripheral ducts communicates with the inside or the outside of the device by means of a side opening (15 or 15 b, 15 c). |
