A device for placement externally of a body fluid flow conduit, comprising a tubing portion defining a longitudinally extending cavity for receiving the conduit, the longitudinal cavity of said tubing portion being substantially free of ribs or grooves, wherein the centre line of the longitudinal cavity follows a substantially helical path with a helix angle less than or equal to 65~, and wherein the amplitude of the helix is less than or equal to one half of the internal diameter of the tubing portion.

L'invention concerne un dispositif servant à placer à l'extérieur un conduit d'écoulement d'un liquide organique. Le dispositif comprend une partie de tube souple délimitant une cavité qui s'étend longitudinalement pour recevoir le conduit. La cavité longitudinale de ladite partie de tube souple est sensiblement dépourvue de nervures ou de rainures. La ligne médiane de la cavité longitudinale suit un chemin sensiblement hélicoïdal présentant un angle d'hélice inférieur ou égal à 65·. L'amplitude de l'hélice est inférieure ou égale à la moitié du diamètre intérieur de la partie de tube souple.
