Title
(EN) INFLATABLE ROTOR FOR A FLUID PUMP
(FR) ROTOR COMPRESSIBLE POUR POMPE À FLUIDE
Abstract
(EN)
The invention relates to a rotor (2, 15) for a fluid pump (1), in particular for use in the medical sphere, the rotor being compressible for bringing to the place of use and thereafter being expandable. The compressibility is assisted by the provision of cavities (27, 28, 29), in particular also production of the rotor at least partially from a foam.
(FR)
L'invention concerne un rotor (2, 15) pour une pompe à fluide (1), destiné en particulier à être utilisé dans le domaine médicale, le rotor étant compressible pour pouvoir être amené à son emplacement d'utilisation, puis expansé. La compressibilité est favorisée du fait qu'il existe des cavités (27, 28, 29), et également, en particulier, du fait que le rotor est produit au moins partiellement à partir de mousse.
