Syringe holder and injection device
First Claim
1. A syringe holder for holding an inserted cylindrical syringe, with a cap attached to a male luer provided at the distal end thereof, comprising a generally cylindrical barrel portion having an open distal end and an open proximal end, and a finger rest projecting in the lateral direction from the outer surface of the barrel portion at a position relatively closer to the proximal end of the barrel portion, wherein a stopper means is provided at the inner surface of the barrel portion at the distal end thereof, the stopper means being designed to abut on the outer edge of the distal end of the syringe to block forward movement of the syringe, wherein a female-threaded sleeve is provided which extends forwardly from the distal end of the barrel portion, the female-threaded sleeve being provided with a thread designed to surround the male luer provided at the distal end of the syringe and the cap attached to the male luer, and wherein a proximal end cap is provided, at the proximal end of the barrel portion, the proximal end cap being designed to cover the proximal end of the barrel portion and to abut on the outer edge of the proximal end of the syringe to block backward movement of the syringe, and the proximal end cap having a bore through which to pass a piston rod that is to be connected to a gasket in the syringe.

Abstract
An injection device adapted to the luer lock system and a syringe holder for making it is disclosed. The syringe holder for holding an inserted syringe, with a cap attached to the male luer at the tip, comprises a cylindrical barrel portion having an open distal end and an open proximal end, and a finger rest around the outer surface of the barrel portion at a position relatively closer to the proximal end, wherein a stopper means is provided at the inner surface of the barrel portion at the distal end thereof, the stopper means being designed to abut on the outer edge of the distal end of the syringe, and wherein a female-threaded sleeve extends forwardly from the distal end of the barrel portion, which is designed to surround the tip of the syringe and the cap, and wherein a proximal end cap is provided, at the proximal end of the barrel portion, which is designed to abut on the outer edge of the proximal end of the syringe, and has a bore to pass the piston rod through.
