Abstract

La presente invenzione ha per oggetto un regolatore di flusso ad alta precisione per linee d'infusione medicale. Il regolatore comprende un corpo fisso (2) con una cavità interna (5) sostanzialmente cilindrica provvista di un condotto di ingresso (7) ed uno di uscita (8), ed un elemento valvolare mobile (3) inserito girevolmente nella cavità interna di detto corpo per variare selettivamente la portata tra i condotti (7, 8). L'elemento valvolare (3) comprende mezzi di occlusione (15) destinati ad interagire con una fessura calibrata (13) formata sulla parete laterale del corpo fisso (2) in corrispondenza del canale d'ingresso (7), parallelamente all'asse della cavità (5) per una lunghezza approssimativamente pari al diametro interno del condotto di ingresso (7). L'elemento mobile (3) presenta una porzione tubolare (11) avente ad una estremità un bordo (15) con profilo elicoidale che definisce i mezzi di occlusione. Il regolatore e costituito da due soli pezzi e perciò è estremamente economico, è poco sensibile alle variazioni di viscosità e pressione del fluido.
