Injecting apparatus

An automatic injector for delivering a fluid, comprising:

• a housing, said housing having a proximate end and a distal end;
• a shield interfaced with the housing at a housing distal end and wherein said housing and said shield are arranged in a sliding relationship forming an enclosure, said shield comprising a base having an aperture positioned at said distal end of said housing;
• a driver positioned within said enclosure and engaged to the housing and adapted to automatically disengage from the housing upon displacement of said shield towards said proximate end of said housing;
• a cartridge positioned within said enclosure, and wherein said cartridge comprises:
• a needle extending towards said shield base, said needle being disposed within said shield prior to displacement of said shield, said needle passing through said aperture when said shield is displaced;
• and
• a barrel, said barrel arranged to contain a stopper and the fluid therein and wherein the fluid is in communication with said needle;
• said driver slidingly located within said housing for forcing the fluid through said needle upon activation of said injector;
• and
• said driver further adapted to be biased by a driving unit, said driving unit causing said driver to slide towards said housing distal end and move a stopper through said barrel to push the fluid through said needle for delivery into an injection site;
• and
• wherein said shield is automatically deployed following fluid delivery so as to cover the needle.

• and
• a barrel, said barrel arranged to contain a stopper and the fluid therein, the fluid in communication with said needle;
• a rod, forming a portion of said driver, arranged to communicate with said stopper before the activation, said rod arranged to move said stopper for titration before the activation and to automatically separate from said stopper upon activation;
• said driver being slidingly located within said housing for forcing the fluid through said needle upon activation of said injector;
• said driver further adapted to be biased by a driving unit and said driving unit causing said driver to slide towards said distal end and move said stopper through said barrel to push the fluid through said needle for delivery into an injection site;
• and
• wherein said shield is automatically deployed following fluid delivery delivery so as to cover the needle.

An injector for automatically injecting and delivering fluids into a living being, said injector comprising:

• a housing having a proximal end and a distal end that is open;
• a cartridge having a barrel containing a fluid, said cartridge further comprising a displaceable stopper at a proximal end of said cartridge and a needle at a distal end of said cartridge, said cartridge being fixed within said housing;
• a driver engaged within said housing for driving said stopper to dispense the fluid from said barrel and through said needle when disengaged from said housing;
• a needle shield being in sliding engagement with said distal end of said housing and comprising an opening for permitting said needle to pass therethrough, said needle being disposed within said needle shield prior to activation of said injector;
• and
• a single spring, engaged with said driver, that is released by a user force, said single spring displacing said driver for automatically injecting and delivering the fluid into the living being and for automatically acting against the needle shield to remove the needle from the living being while automatically concealing the needle within said shield once the fluid delivery is complete.

An automatic injector for delivering a fluid, comprising:

• a housing, said housing having a proximate end and a distal end;
• a shield interfaced with the housing and comprising a shield base having an aperture;
• said housing and said shield arranged in a sliding relationship forming an enclosure;
• said driver positioned within said enclosure;
• a cartridge positioned within said enclosure, said cartridge comprising:
• a needle extending towards said shield base, said needle being disposed within said shield prior to displacement of said shield, said needle passing through said aperture when said shield is displaced;
• and
• a barrel, said barrel arranged to contain a stopper and the fluid therein, the fluid in communication with said needle, said driver slidingly located within said housing for moving the needle forward to insert it into tissue and for forcing the fluid through said needle upon activation of said shield;
• a driver attached to the housing and adapted to automatically disengage from the housing upon activation of the injector;
• said driver further adapted to be biased by a driving unit and said driving unit causing said driver to slide towards said distal end to forward the cartridge with the needle and move said stopper through said barrel to push the fluid through said needle and deliver fluid into an injection site;
• and
• wherein said shield is automatically deployed following fluid delivery so as to cover the needle.
