ORTHO® ALL-FLEX® Arcing Spring Diaphragm
The ALL-FLEX® is a diaphragm with a shallow dome and a flexible rim with an arcing spring. The ALL-FLEX® diaphragm is now made from Silicone rather than latex rubber and is available in 4 sizes (65, 70, 75 and 80mm). According to Ortho-McNeil-Janssen Pharmaceuticals, Inc., the switch from latex to Silicone is expected to reduce allergic adverse events experienced with latex. The ALL-FLEX® diaphragm is available in the United States and elsewhere, though as of 2008 it has been discontinued in Canada. It is the world market leader in diaphragm sales and distribution.
