Pole-syringe for injecting from a remote distance
First Claim
1. A syringe device for administering hypodermic injections, the device comprising:
- an elongated open ended sleeve;
a plug mounted in one end of said sleeve and having an inner end and an outer exposed end, said plug having a hole formed therethrough from end to end, said hole being radially enlarged proximate said outer end to provide said plug with an annular convex surface from said hole to said outer end; and
a hypodermic syringe having an elongated barrel, a needle hub affixed to one end of said barrel, a needle mounted on said hub, and an elongated plunger slidably mounted in the other end of said barrel;
said syringe slidably mounted in said sleeve with said hub abutting said plug inner end and said needle projecting through said hole.

Abstract
A syringe device for administering hypodermic injections and comprising a conventional hypodermic syringe, an elongated pole secured to the plunger of the syringe and a sleeve frictionally slidable over the syringe barrel. The sleeve having a plug mounted in one end thereof which has a hole drilled axially therethrough for receiving the syringe needle wherein the hole on the outer exposed side of the plug is radially enlarged to provide the plug with an annular convex surface from the hole to the outer end of the plug, thus permitting the needle to bend in an arc about the annular convex surface in the event the animal moves during the injection process. The inner side of the plug is countersunk around the hole to provide a seat for the needle hub.
