Abstract
The invention concerns a device comprising two components connected to each other with possible displacement of one component relative to the other, sealing means arranged between said two components, and flow rate adjusting means actuated by displacement of one component relative to the other. The invention is characterized in that the device comprises positioning means for placing the two components in two different positions, namely a first so-called sterilizing position, wherein said two components do not, or hardly exert, any stresses on the sealing means, and second so-called operating position, wherein said two components stress the sealing means to provide the required sealing conditions.
Claims9
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, 35a to 35d, 36a to 36c) 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.
