What is the primary function of the turret in an automatic injector?

The turret in an automatic injector is primarily designed to securely hold a syringe, typically one that has a capacity of either 150 ml or 200 ml. This feature is essential because the injector is used to deliver contrast agents or medications at precise volumes during imaging procedures. By holding the syringe in place, the turret ensures that the injection is accurately administered and that the connection to the intravenous access point remains stable throughout the process.

In the context of an automatic injector, the turret's role is crucial for setting up the device for efficient operation, allowing the clinician to focus on other aspects of the procedure while ensuring that the volume of contrast or medication needed is administered correctly. This integral function of the turret supports the overall reliability and efficiency of the injector during interventional radiology procedures.
