Abstract
An improved hypodermic syringe including finger-holding surfaces that substantially or completely surround the operator finger and include an interior tapered portion to better engage a finger, which facilitates one-handed use by allowing the same hand that holds the syringe to operate the plunger conveniently to accomplish both the distal (injecting) stroke and the proximal (aspirating) stroke.
