What is the primary difference between Luer-Lok and non-Luer-Lok syringes?

Luer-Lok syringes feature a locking mechanism that allows the needle to be securely attached to the syringe. This mechanism involves a threaded connection that provides a more stable fit compared to non-Luer-Lok syringes. When using a Luer-Lok syringe, the needle is twisted into place until it locks, which minimizes the risk of disconnection during injection or aspiration procedures. This is particularly important in medical settings where safety and precision are paramount, as it reduces the chances of leaks or accidental dislodgement, ensuring reliable medication delivery.

The other syringe types often have a slip tip design, where the needle simply slips onto the end of the syringe without a locking mechanism, increasing the risk of accidental disconnection during use. Thus, the primary difference lies in the secure attachment system of the Luer-Lok syringes, which enhances safety and efficacy in medical applications.
