Abstract
A capless medical valve includes a housing defining an inlet, an outlet, and a valve bore, all three of which meet at a common transition zone bounded by a transition surface. A valve member confined within the valve bore has a spherical head and a generally cylindrical stem sized to fit within the inlet and extending from the head toward the transition zone. A spring in compression biases the valve member toward the inlet, so that the spherical head is normally seated against the transition surface, but can be mechanically displaced off its seat by inserting a syringe tip or fitting into the inlet.
