  • Patent number: 4950279
    Abstract: An acupuncture needle delivery system is disclosed comprising a needle with an upper head portion that is wider in the middle than at its ends. The needle is packaged within a plastic dispensing tube which is greater in diameter than the needle, except at the end of the tube which surrounds the needle's head. The portion of the tube surrounding the head of the needle is narrower than the widest part of the head to snugly grasp the head and secure the needle within the tube. Upon the imposition of axially directed, manually exerted, downward pressure on the head region, the end of the plastic tube stretches, permitting the needle to be ejected from the other end of the tube.
