Abstract

Il presente trovato si riferisce ad un ossigenatore di sangue con struttura cilindrica dotata di una parete interna e di una parete esterna delimitanti una porzione di spazio per il contenimento di uno strato di capillari in membrana microporosa destinati ad essere lambiti esternamente dal sangue, che percorre con direzione sostanzialmente perpendicolare ai detti capillari la porzione di spazio dotata di vie di comunicazione con l'esterno. I capillari sono annegati alle estremità in anelli di resina poliuretanica denominati potting e aperti su camere rispettivamente di entrata di ossigeno e di uscita di anidride carbonica.La peculiarità del trovato è costituita dal fatto di comprendere nervature che si derivano dalla parte interna della struttura suddivise in una pluralità di gruppi estesi per tutta la lunghezza della struttura stessa.Le nervature sono atte a determinare un andamento ondulato dello strato di capillari, con presa di contatto da parte dello stesso con la parete esterna della struttura nelle zone di contatto con le nervature e distacco dalla parete esterna, con presa di contatto con la parete interna della struttura nelle zone comprese fra due gruppi adiacenti di nervature.
