ABSTRACT:
A device for regulating the flow rate of a medical liquid includes a body provided with elements associated with corresponding parts connected together but torsionally free, at least one of the parts including a plurality of recesses acting as flow regulator able to modify the flow rate of the liquid directed towards the patient by rotating the parts about a common axis of rotation. Between the parts a seal element enables the recesses to be selectively connected together via communication elements, so achieving flow rate regulation. Transverse sealers are provided between the seal element and at least the second part of the parts which are interconnected but torsionally free. The transverse sealers preventing the escape of liquid from the recesses and from the body of the device following a relative movement or misalignment between the parts in a plane perpendicular to the axis of rotation or along this latter during flow regulation or following any angular misalignment of the parts relative to the axis.
