What feature distinguishes a Leur lock syringe from other types?

A Leur lock syringe is characterized by its twist-on mechanism for needle attachment, which allows for a secure connection between the syringe and the needle. This feature is essential for preventing accidental disconnection during injection, which could lead to spills or loss of medication. The twist mechanism provides a tight seal that enhances safety and reduces the risk of contamination.

In contrast, other types of syringes, such as those with a slip tip design, do not have this secure locking mechanism, which makes Leur lock syringes preferable in many medical settings, particularly when dealing with hazardous medications or intravenous administration. The use of a Leur lock also facilitates better control and stability when drawing or administering fluids.

While disposable syringes are common in practice, not all Leur lock syringes must be disposable, and their calibration in units of blood volume is not a distinguishing feature of this syringe type. Instead, Leur lock syringes can come in various calibration scales depending on their intended use. Thus, the twist-on mechanism is the defining characteristic that sets a Leur lock syringe apart from other syringe types.
