Abstract
A valve, suitable for use in small medical devices and which can readily be made of medical grade materials, comprises an elastic diaphragm stretched over a protruding surface, preferably of spherical or convex shape. The diaphragm has a ring of holes concentrically around a hole in the protruding surface. A mating recess, connected to a conduit, fits over the protruding surface. The elastic material is held in place at or near the opening of the recess. The holding structure may also serve to seal the valve. A dual arrangement provides an input and an output valve in combination.
