Abstract

L'invention porte sur une pompe péristaltique, qui comprend une tête de pompe (110) et un support de cartouche (112) disposé au voisinage de la tête de pompe, et une cartouche amovible (104) ayant un bâti (140) disposé dans le support de cartouche. La cartouche comprend un premier orifice (102) fixé au bâti et conçu pour accepter un premier type de récipient (194), un second orifice (144) fixé au bâti et conçu pour accepter un second type de récipient (206) différent du premier type de récipient, une trajectoire de fluide (146) disposée en partie dans le bâti et couplée à une première extrémité au premier orifice, et à une seconde extrémité au second orifice. La trajectoire de fluide a une tubulure définissant une surface disposée en contact direct avec la tête de pompe de façon à provoquer le déplacement d'un fluide le long de la trajectoire de fluide entre le premier orifice et le second orifice. La pompe péristaltique comprend de plus un support de récipient réglable (220) adjacent au support de cartouche (112), le support de récipient réglable ayant une partie dressée vers le haut dans laquelle le second récipient disposé en son sein est dans une première orientation par rapport au second orifice (144), et une position inversée dans laquelle le second récipient est dans une seconde orientation différente de la première orientation et inversée par rapport à cette dernière.
