Abstract

Cassette (18) para ser asociado operativamente con una bomba peristáltica, presentando el cassette un cuerpo relativamente rígido que define un sustrato exterior (22), comprendiendo la bomba unos medios de rodillo rotativos (12,14,16) adaptados para agarrar y pellizcar una porción de un canal para fluidos con paredes flexibles (26) contra el sustrato (22) de tal modo que empuja el fluido contenido en el mismo a lo largo del canal, caracterizado porque dicho canal para fluidos está formado entre dicho sustrato rígido exterior (22) y dicha lámina elastomérica (20) fijada al sustrato (22), presentando dicha lámina elastomérica por lo menos un canal (26) moldeado en su interior y contenido en el mismo, extendiéndose dicho canal o canales exteriormente desde el sustrato exterior (22).
