Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
An acupuncture needle delivery system comprising: an axially extending needle having an upper head portion, having a mid-portion a middle handle portion and a relatively slender lower body portion terminating in a leading point, the mid-portion of the head portion being slightly larger in cross-section than the end portions of the head portion, a deformable plastic tube having a first and a second end portions and a tube body disposed therebetween, said tube body having an inner diameter along substantially its entire length which is greater than any portion of the needle, the first end portion of the plastic tube being open and the second end portion having a circumferential lip means disposed thereon, said circumferential lip means defining a through-hole of a slightly lesser cross-section than the widest part of the head region, the needle being mounted within the tube for discharge therefrom, with its head region snugly grasped within said second end portion of the tube, the widest cross-section of the head portion being within the limits to which the circumferential lip means of the plastic tubing will expand upon the imposition of axially directed, manually exerted, downward pressure on the head region, whereby the needle is ejected from the other end of the tube.
