Abstract
Needle and high velocity jet hypodermic injectors employ a tubular liquid chamber, a suitable output port i.e., a needle or a jet port, and corresponding means for applying pressure to collapse the liquid chamber. The needle injector includes a needle sheath which automatically covers the needle after use and inhibits reuse of the needle. The jet injector electronically controls and monitors the system parameters of operation to assure successful injection results.
