Abstract
Abstract An unrestricted passage is provided through a piercing device; therefore, when the device pierces a stopper of a bottle containing intravenous solution, additives may be injected into the bottle or a portion of the liquid in the bottle may be withdrawn through the unrestricted passage. The unrestricted passage may be opened by removing the cap or by piercing a diaphragm with a needle.
