1. A new and improved apparatus for drawing fluid into a hypodermic syringe comprising, in combination:

  • a hypodermic syringe of the type having a cylindrical container for fluids to be dispensed, the hypodermic syringe having an open proximal end and a distal end with a needle at the distal end and a shoulder at the proximal end, the hypodermic syringe also having a reciprocal rod with a distal end formed with a piston positioned interior of the container, the rod also having a proximal end with a plunger for reciprocating the piston for drawing fluids into the cylinder and the forcing of fluids therefrom;

    a vial having a closed cylindrical extent at its lower end and a neck of a reduced diameter with an opening at its upper end and a closure pierceable by a needle, the bottle also having a quantity of medicinal fluid therein for being drawn from the vial by a needle of a hypodermic syringe;

    a holder having a distal end and a proximal end and a central extent therebetween with a planar lower surface therebeneath, the distal end including an upper support surface adapted to support the vial of medicinal fluid, the support surface being formed at an angle of about 30 degrees with respect to the lower surface and sloping downwardly toward the central extent of the holder, the upper surface of the proximal end being planar and provided with a forward stop perpendicular to the upper surface;

    a reciprocable platform having a proximal end and a distal end with a lower horizontal surface slidable upon the upper surface at the proximal end of the holder, the platform also having an upper surface formed with a curvature adapted to receive thereon the hypodermic syringe, the platform also having an upturned distal end adapted to limit the withdrawal movement of the plunger, the platform also having a recess at a central extent adapted to receive the shoulder to preclude axial movement thereof; and

    a base having a planar upper horizontal surface adapted to receive thereon the lower horizontal surface of the holder with coupling components therebetween.
