Patent ID: 8267902

Claim:
A syringe device, comprising: a syringe comprising a front end and a rear end, an axially extending hollow needle that projects from the front end, a rear end of the needle being in fluid communication with a space that extends substantially to the rear end of the syringe, a plunger comprising a piston arranged in the space and a piston rod extending axially from the piston and out of the rear end of the syringe, wherein the piston is movable to and fro in the space, and wherein the plunger is designed such that, when drawn out to a drawn out position, wherein the piston rod extends axially from the rear end of the syringe, the plunger causes liquid to be drawn through the needle and, when pressed in, causes liquid to be discharged through the needle, and a radially projecting grip element configured and dimensioned to be gripped between a thumb and middle finger of a hand of a user while pressing on the piston rod using an index finger of the hand to carry out injection, wherein the grip element has an extent in an axial direction and is circumferentially arranged about a front portion of the syringe, and a capsule device comprising at least one rear sleeve element which is dimensioned such that, when the plunger of the syringe is drawn out to the drawn out position, the at least one rear sleeve element will cover the piston rod of the syringe such that, when the at least one rear sleeve element is engaged over the piston rod, the plunger cannot be pressed in, wherein the capsule device further comprises at least one front sleeve element designed to cover the needle of the syringe when the syringe is not in use, the grip element of the syringe being designed such that, upon engagement of the at least one front sleeve element, the grip element acts as a limit stop for the at least one front sleeve element, and wherein the grip element of the syringe is designed such that, upon engagement of the at least one rear sleeve element, the grip element acts as a limit stop for the at least one rear sleeve element.
