Syringes come in a number of designs The common tip styles are luer lock, slip tip, catheter tip, and eccentric tip.
A Luer lock is a screw connection on a syringe that creates a leak-free seal. Care providers can connect needles, tubing, and other equipment to the lock.
The 50/60ml catheter tip/long tip can be used for gastroenteral feeding, manual aspiration of liquids or gas from stomach, manual pharyngeal or tracheal aspiration/suction.
DIFFERENCE BETWEEN LEUR LOCK AND LEUR SLIP.
The luer slip syringe requires the medical staff to push the hypodermic needle onto the syringe end, creating a secure strong connection. Luer lock syringes requires the hypodermic needle to be screwed on, rotating the needle clockwise can achieve a very tight fit bond between the needle and the syringe.
