Abstract:
A valve for medical and therapeutic use comprising a fitting in the form of a rigid frame and a shutoff device consisting of an assembly of vanes, with surfaces which are approximately flat, connected to the frame by articulations and pivoting about these articulations during the opening process under the effect of the introduction of the fluid, the frame and the vanes forming one single piece, in which the vanes are elements which are inherently rigid and the articulations are areas which are elastically deformable, being flexible about a rectilinear axis located between the vane and a corresponding portion of the frame, wherein the vanes are shaped in such a way as to ensure the maximum cross-section for the passage of the laminar airflow in the open position the retention of the fluid in the closed position by the exclusive support of their border edges against one another.
