Abstract
Syringe drivers and injector devices are provided. The driver includes a housing including a port communicating with a gas chamber therein and connectable to an external air source, and a cavity that receives a syringe containing an agent. A drive piston within the housing includes a first end disposed adjacent the gas chamber and a second end including a plunger connectable to the syringe. A damping mechanism is provided within that housing that is coupled to the drive piston that includes a damper piston within a damping fluid chamber such that, when the drive piston is advanced by gas delivered into the gas chamber from the external source to deliver the agent from the syringe, damping fluid within the damping fluid chamber flows through an orifice or valve from a first region to the second region, thereby limiting movement of the drive piston.
