Why is it called Luer lock?
Named after German instrument maker, Hermann Luer, Luer fittings are among the earliest medical fittings designed to provide leak-free connections between syringes and needles and maintain a continuous lumen for fluid flow.
How does a Luer lock needle work?
Luer lock syringes for detachable needles work by having a twist fit thread around the tip of the syringe for the needle to screw down onto form a more permanent seal. ALL detachable needles have two small tabs on the outside that fit into this thread, so that they can be fitted to luer lock syringes.
What is the difference between Luer lock and Luer 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.
Are all needles Luer lock?
Syringes can either be Luer Lock or non Luer lock, however non Leur Lock are also referred to as Luer Slip. The difference is that the Luer Lock syringe allows a needle to be twisted onto the tip and then locked in place.

Who invented the Luer lock?
The Luer lock, first developed in 1930 by the R&D team at Becton-Dickinson, utilizes a threaded connection for a more secure fit. The lock connection is further categorized into two distinct types; the standard one-piece and a two-piece rotating collar Luer lock.
When were luer locks invented?
In 1930, a patent for the Luer-Lok connection was granted to Fairleigh S. Dickinson, cofounder of Becton Dickinson. The addition of locking flanges addressed the Luer's tendency to pop open under pressure and enabled users to connect the needle to the syringe by twisting to engage interlocking cams.
Is luer a word?
(lū'ĕr), early 20th-century German instrument maker.
Is a Luer lock syringe male or female?
Syringes are one of the most common instruments using the luer fitting system with the male luer connection fitting the female needle which either screws into it or fits tightly on top. These can be split into two varieties by the connection type: locking or slipping.
What is a locking luer lok?
The locking ‘Luer-Lok’ style are more secure, the needles are inserted into the syringe and twisted to form a locked connection; ensuring no liquids can leak and prevents accidental removal of the needles .
What is a luer fitting?

What does "t" mean on a luer thread?
The “t” dimension. The new luer standard specifies the “t” dimension for the male luer thread.
How to have a mating luer?
To have a mating luer under ISO 594, the threads should meet the thread pitch, thread width and correct angles. Once you factor in different materials and clause 3.2.2, the waters become muddy quickly. As you can see from the pictures above, there is an interpretation issue. If the luer thread from one manufacturer has a thread that starts further back inside the male luer connector it will allow the luer tapers to engage, however, the locking function is compromised. Conversely, if the thread is too aggressive, it will not allow the luer tapers to correctly seal resulting in over rotation and a potential leak.
What is the highest volume user of luers?
2. If your application does not fall into this group, understand that intravascular and hypodermic applications are the highest volume users of luers as evidenced by the title of ISO 80369-7. As component manufacturers adjust tooling to meet the new standard, the old ways of manufacturing ISO 594 luers to performance requirements only, will eventually be abandoned.
What is the new luer standard?
As many of us in the medical device industry have heard there is a new luer standard called ISO 80369-7. This standard applies specifically to intravascular and hypodermic applications with the goal of standardising the luer taper and thread. However, the impact will most likely affect everyone that uses a plastic luer.
Do luer mate?
This is why many component manufacturers state their luers “mate with” other luers designed to the standard. They therefore pass the performance requirements, but not all of the dimensional requirements. Depending on the end user, the luer can either be in compliance or not.
Will plastic luer go live?
However, the impact will most likely affect everyone that uses a plastic luer. Many original equipment manufacturers are currently in the process of considering this change even though the “go live” date has been pushed back by the Food and Drug Administration (FDA).
Is a plastic luer backwards compatible?
ISO 80369-7 used some of the requirements and parameters from ISO 594 where applicable. Therefore, if a luer complies with ISO 80369-7, it is backwards compatible to ISO 594. A plastic luer that only passes performance testing (ISO 594) will not be compatible with ISO 80369-7.
