CA 2479127

A pump (10) includes a housing (12) defining a tube receiving portion (26) and a blade (102) mounted for reciprocating movement between first and second positions. In its first position, the leading edge (104) of the blade (102) compresses a length of tube (30) against a first surface disposed in the tube- receiving portion (26), while in the second position, the blade (102) does not compress the tube (30). The tube-receiving portion (26) can receive the tube (30) directly or indirectly through a tube set (60) detachably mounted to the housing (12). The tube set (60) includes a tube (30) and a base (62) having first and second end portions (64, 66) that respectively define first and second tube-receiving apertures (68, 70) for slidably receiving a length of the tube (30) therethrough. The base (62) has a first surface (72) constructed to engage the length of tube (30) between the apertures for compression by the pump blade (102).

L'invention concerne une pompe (10) qui comprend un boîtier (12) définissant une partie de réception de tuyau (26) et une lame (102) assemblée pour un mouvement alternatif entre une première position et une seconde position. Dans sa première position, le bord d'attaque (104) de la lame (102) comprime une portion du tuyau (30) contre une première surface placée dans la partie de réception du tuyau (26), alors que dans la seconde position, la lame (102) ne comprime pas le tuyau (30). La partie de réception du tuyau (26) peut recevoir le tuyau (30) directement ou indirectement à travers un ensemble tuyau (60) assemblé de façon amovible au boîtier (12). Cet ensemble tuyau (60) comprend un tuyau (30) et une base (62) possédant des première et seconde parties d'extrémité (64, 66) qui définissent respectivement des première et seconde ouvertures de réception du tuyau (68, 70) destinées à recevoir de façon coulissante une portion du tuyau (30). La base (62) possède une première surface (72) conçue pour engager la portion de tuyau (30) entre les ouvertures, pour compression par la lame de pompe (102).
