Abstract

A switching device for a fluid distribution set (100) presenting a deformable portion (15) having a first port (24), a second port (25), a third port (26) and a fourth port (27), is disclosed. The switching device comprises an active portion (16a) adapted, in use, for clamping the deformable portion (15) of the fluid distribution set, and a housing body defining a seat for receiving the deformable portion (15). The switching device can be operated according to at least a first and a second clamping positions, wherein the active portion (16a) is approached to a corresponding active surface of the housing body. A fluid control apparatus comprising the above switching device and the portion (15) of the fluid distribution set (100) is also described.
