Which of the following types of syringes is characterized by a locking mechanism for the needle?

The Leur lock syringe features a specialized locking mechanism designed to securely attach the needle to the syringe. This design prevents accidental disconnection during procedures, which is crucial for maintaining sterility and ensuring the precise delivery of medications or contrast agents. The locking mechanism is a prominent feature that differentiates it from other types of syringes, enhancing safety during administration.

In practice, this safety feature minimizes the risk of needle disengagement, which can lead to medication spills or exposure to contaminants, thus ensuring a higher level of patient care. The Leur lock system is commonly used in various medical settings, particularly in radiology, where accurate delivery of contrast media is vital.

In contrast, other syringes, like the conventional syringe, do not have this specific locking feature, relying instead on friction to hold the needle in place, which can lead to disconnection if not handled carefully. The straight syringe and catheter syringe also lack the locking mechanism found in the Leur lock syringe, making them less ideal for situations requiring secure needle attachment.
