an enclosure;
an attachment for securing the enclosure to the wearer;
an injection cylinder within the enclosure;
an injection piston within the injection cylinder configured for movement within the injection cylinder;
at least one hypodermic needle carried by the injection piston for insertion into the wearer;
wherein the injection piston divides the injection cylinder into a first portion containing the fluid to be injected and a second portion containing an insertion end of the at least one hypodermic needle;
a valve member located within the first portion of the injection cylinder containing the fluid to be injected and blocking flow of the fluid to be injected to the at least one hypodermic needle; and
at least one tether secured to the valve member to limit movement of the valve member so that the valve member permits flow of the fluid to be injected from the injection cylinder above the injection piston to the at least one hypodermic needle when the injection piston moves a distance adequate to insert the at least one hypodermic needle into the wearer.
