Abstract
Over-molded regulator bags for a fluid delivery system are disclosed that are formed by over-molding a resilient bladder of an elastomeric material on a supporting rigid host substrate. The over-molding process allows three dimensional lung designs to be created without extra processes, and without stressing the membrane material. Embodiments of the invention eliminate the need for an external spring to create an opposing pressure to deflate the bags when required. The inherent elasticity of the over-molded bladders act as the restoring force to return the expanded bag back to its original form.
