Claim Text:
1. A syringe for delivering medicine to animals upon pressurization comprising: a cylindrical barrel having a central axis, a proximal end and a distal end; a nosehub positioned at the distal end of the cylindrical barrel, wherein the nosehub further comprises; a center point, a top and a base, wherein the base is placed within the distal end of the cylindrical barrel and the top remains outside of the cylindrical barrel, and a first circular opening located at the center point of the nosehub, wherein the first circular opening extends beyond the base of the nosehub and a second circular opening wherein the first circular opening is larger than the second circular opening and wherein the second circular opening does not extend beyond the base of the nosehub, a tailpiece end cap positioned at the proximal end of the cylindrical barrel, wherein the tailpiece end cap comprises a proximal end further comprising a portal, and a distal end further comprising an air vent, wherein the portal and the air vent are adjacent, a tailpiece comprising a proximal end and a distal end, wherein the distal end of the tailpiece comprises an interior, further comprising an opening, and an exterior wherein the exterior of the distal end of the tailpiece is secured within the portal of the proximal end of the tailpiece end cap, and wherein the tailpiece further comprises; an air vent, wherein the air vent is located proximally adjacent to the opening, a plurality of flexible fins, wherein the plurality of flexible fins extend longitudinally from the proximal end of the tailpiece and extend beyond the proximal end of the tailpiece and are flexible between 90° and 180° relative to the tailpiece from the distal end of the tailpiece to the proximal end of the tailpiece, a one-way air valve positioned within a space between the air vent of the base of the tailpiece and the air vent of the tailpiece end cap created by the opening of the tailpiece and the portal of the tailpiece end cap, a soft plunger positioned within the cylindrical barrel moveable longitudinally within the cylindrical barrel between the tailpiece end cap and the nosehub, whereby the cylindrical barrel is divided by the soft plunger into an air pressure chamber in the proximal end of the cylindrical barrel and a chamber suitable for receiving medicine in the distal end of the cylindrical barrel, a needle, wherein the needle comprises a proximal end, a central passageway, and a distal end and the proximal end is secured within the first circular opening of the nosehub and the distal end extends beyond the nosehub, a safety cap, wherein the safety cap comprises;
