ABSTRACT:
A switching device for a fluid distribution set presenting a deformable portion having a first port, a second port, a third port and a fourth port, is disclosed. The switching device comprises an active portion adapted, in use, for clamping the deformable portion of the fluid distribution set, and a housing body defining a seat for receiving the deformable portion. The switching device can be operated according to first and second clamping positions, wherein the active portion is approached to a corresponding active surface of the housing body. A fluid control apparatus comprising the above switching device and the portion of the fluid distribution set is also described.
