<p>The invention relates to a drainage system made up of a drainage tube, a coupling and a drainage hose, in which the drainage hose is made up of a profile that runs along the entire length thereof. The profile of the drainage hose is made up of three symmetrical lobes defined therebetween by three dividing channels. Each lobe is made up of two radial straight walls at the centre of the hose structure and two circumferential curved walls in opposite directions at the periphery of the hose, each radial straight wall is connected to a circumferential curved wall, and a space is formed between the two circumferential curved walls. The radial straight walls and the circumferential curved walls define a lumen; the other side of the radial straight walls defines the dividing channels. The configuration of the drainage hose provides suitable structural strength that can withstand the medical uses of the part, optimising the flow of the drainage fluid, avoiding the risk of any blockage or "sealing" of the drain caused by deposition of the extracted fluids, and preventing complications for the patient when removing the drain from the patient.</p> |
