42 Claims

1. A tube holder for use with a peristaltic pump, the tube holder comprising:

a housing having a recess for receipt of a pump rotor, a tube race for receipt of a tube around the recess and having a first race part around one part of the recess and a second race part around another part of the recess, a first tube inlet into the first race part and a first tube outlet from the first race part, a second tube inlet into the second race part and a second tube outlet from the second race part, the first race part extending between the first tube inlet and first tube outlet and comprising an occluding surface against which part of a tube can be compressed in use by a pump rotor, and the second race part extending between the second tube inlet and second tube outlet and comprising an occluding surface against which part of a tube can be compressed in use by the pump rotor;

the tube being insertable in the tube race by movement in a substantially orthogonal direction relative to the tube race so that it extends in through the first tube inlet, around the first race part, out through the first tube outlet, in through the second tube inlet, around the second race part, and out through the second tube outlet, and such that a portion of the tube between the first tube outlet and second tube inlet is external of the tube race.
