What type of syringe may have the needle disengage if not properly attached?

A slip tip syringe features a design that allows the needle to be pushed onto the end of the syringe without a locking mechanism. Because of this design, if the needle is not firmly attached or if tension or movement occurs during use, the needle can easily disengage from the syringe body. Proper technique is essential when using a slip tip syringe to ensure that the needle remains securely in place during the procedure.

In contrast, a luer lock syringe is designed with a threading feature that securely locks the needle in place, minimizing the risk of disconnection. An Aerogen syringe, which is specialized for aerosolizing medications, also has a secure attachment mechanism. None of these options exhibit the same risk of disengagement as the slip tip design, which is why the slip tip syringe is the most likely to experience needle disengagement if not properly attached.
