Quick-connect syringe and needle system

A quick-connect syringe and needle system, comprising:

• a syringe;
• a needle assembly including a needle assembly body and a needle affixed to the needle assembly body, the needle assembly body including a rear portion defining at least one slot;
• and
• an intermediate adapter, disconnectably threadable to a forward threaded portion of the syringe to secure the intermediate adapter to the syringe, the intermediate adapter comprising at least one projection releasably engageable with the at least one slot in the rear portion of the needle assembly body to disconnectably secure the intermediate adapter to the needle assembly;
• wherein
• the quick-connect and needle system is configured to adopt an assembled configuration in which the intermediate adapter is secured to the syringe by a threading of the intermediate adapter to the forward threaded portion of the syringe, and further in which the intermediate adapter is disconnectably secured to the needle assembly by engagement of the at least one projection of the intermediate adapter with the at least one slot of the rear portion of the needle assembly body of the needle assembly.
