A method and an apparatus for making tube bundles for various medical applications such as oxygenators, dialyzers, and heat exchangers is described. The tube bundle is suitable for use as a heat exchanger in, for example, a blood cardioplegia circuit. The winding apparatus (1) axially winds a flexible tube (30) around a winding core (10). The apparatus (1) includes a tube shuttle (26), a shuttle driver (28) and a core driver (20). The core driver (20) rotates the winding core (10) to distribute the tube (30) on the winding core (10) in layers.

L'invention concerne un procédé et un appareil pour fabriquer des faisceaux de tubes pour diverses applications médicales comme des oxygénateurs, des dialyseurs, et des échangeurs de chaleur. Le faisceau tubulaire peut être utilisé, par exemple, comme échangeur de chaleur, dans un circuit de cardioplégie. L'appareil d'enroulement (1) enroule dans le sens axial un tube souple (30) autour d'une bobine d'enroulement (10). Cet appareil (1) comprend une navette de tube (26), un dispositif d'entraînement de navette (28) et un dispositif d'entraînement de bobine (20). Ce dernier fait tourner la bobine (10) et répartit le tube (30) sur la bobine (10) en couches.
