Patent ID: 7028927

Claim:
A flowrate control device ( 1 ), in particular for medical use, comprising two components ( 2 , 3 ) connected to one another with possibility of displacement of one component relative to the other, sealing means placed between these two components ( 2 , 3 ), and flowrate control means ( 23 , 56 ) actuated by the displacement of one component ( 2 , 3 ) relative to the other; said device ( 1 ) being characterized in that it comprises positioning means ( 15 , 35 a to 35 d , 36 a to 36 c ) allowing the two components ( 2 , 3 ) to be placed in two different positions, without disconnecting the two components ( 2 , 3 ), namely a first position, called the “sterilizing” position, in which these two components ( 2 , 3 ) do not exert, or hardly exert, any stresses on the sealing means, and a second position, called the “operating” position, in which these two components ( 2 , 3 ) stress the sealing means ( 4 ) in such a way as to obtain the required sealing.
