Abstract: A plunger for use with a syringe includes a plunger body defining a central longitudinal axis and having a proximal end, a distal end, and a circumferential sidewall connecting the proximal end and the distal end. The plunger further includes at least one retaining member associated with and extending proximally from the plunger body. The at least one retaining member has a first end connected to the plunger body, a second end proximal to the first end and radially and resiliently deflectable relative to the first end, and at least one catch on the second end. A fluid injector system includes a piston having a plunger engagement mechanism configured for interacting with the at least one retaining element of the plunger to releasably engage the plunger for reciprocally driving the plunger within a barrel of the syringe.

Abstract: A fluid injector system includes at least one syringe configured for injecting medical fluid and a fluid path assembly in fluid communication with the at least one syringe, the fluid path assembly including at least one air detection region. The system includes an air detector configured to detect one or more air bubbles in a fluid path associated with the air detection region, at least one shutoff valve at a distal end of the fluid path assembly, and at least one processor programmed or configured to actuate the shutoff valve in response to the air detector detecting the one or more air bubbles in the fluid path associated with the air detection region to prevent fluid flow out of the fluid path assembly. The fluid path assembly has a length greater than a distance that an air bubble can travel or expand during an actuation time of the shutoff valve.

Abstract: A fluid injector having at least one injector head with a front end configured to releasably receive the at least one syringe is described. The fluid injector further includes at least one pressure jacket releasably associated with the front end of the at least one injector head for securing the at least one syringe during an injection procedure. A connection mechanism releasably connects the at least one pressure jacket to the front end of the at least one injector head. The connection mechanism includes at least one electromagnet.
