摘要:
A device and method for making an injection with a short needle, which includes a needle cannula and a limiter surrounding the needle cannula and includes a skin engaging surface on the limiter. The limiter is moveable from a first position in which an elongate portion of the needle cannula is exposed for access to a medication vial, to a locked second position in which the limiter is not movable from the second position to the first position. In the second position, the needle tip extends beyond the skin engaging surface a distance which is ordinarily unable to access the vial.
