Abstract
A medical valve assembly comprises a valve body having a fluid passage therethrough, a valve member, and an urging means disposed within the fluid passage. The valve member is adapted to seal against a sealing surface of the fluid passage and the urging means is adapted to urge the valve member against the sealing surface. The medical valve can be used without a needle thereby eliminating risks associated with needle stick injuries. In applications where it is expedient to use a needle (such as prepackage medications) the medical valve accommodates the use of a needle to administer medication. The urging means is disclosed in a first embodiment wherein it is formed integral with the head portion of the valve member. In an alternative embodiment, the urging means is separate from the head portion of the valve member and is comprised of a metallic spring element.
