Abstract

Macchina (1) per dialisi, in cui un filtro (2) presenta una prima (3) ed una seconda camera (4) fra loro separate da una membrana (5), e delle quali la prima camera (3) è atta ad essere attraversata da un flusso di sangue di un paziente (7), e la seconda camera (4) è atta ad essere attraversata da un flusso di liquido dializzante, il quale è immesso all'interno della seconda camera (4) sotto il controllo di un primo sensore (10), ed è estratto dalla seconda camera (4) stessa sotto il controllo di un secondo sensore (11); la macchina (1) essendo provvista di un primo (13) e di un secondo dispositivo deviatore di flusso (14) disposti a monte ed a valle del filtro (2) per by-passare il filtro (2) stesso e per collegare, tramite un circuito (12) di calibrazione del sensori (10) (11), i sensori (10) (11) stessi in serie fra loro, e di un serbatoio (17) di accumulo interposto tra il secondo dispositivo deviatore (14) ed il secondo sensore (11) per immagazzinare una quantità determinata di liquido dializzante uscente dalla seconda camera (4).
