Luer Taper
The Luer taper is a standardized system of small-scale fluid fittings used for making leak-free connections between a male-taper fitting and its mating female part on medical and laboratory instruments, including hypodermic syringe tips and needles or stopcocks and needles. Currently ISO 80369 governs the Luer standards and testing methods. History Named after the Lüer-family who founded the medical instrument maker Maison Lüer in Paris, the two piece syringe invented by either the employed instrument maker Karl Schneider or Jeanne Lüer together with the glass blower Fournier, it was patented by Jeanne's husband Hermann Wülfing Lüer in 1894, with international patents taken out the following years. It originated as a 6% taper fitting for glass bottle stoppers (so one side is at 1.72 degrees to the centerline). Key features of Luer taper connectors are defined in the ISO 594 standards. It is also defined in the DIN and EN standard 1707:1996 and 20594-1:1993. In 1930, Fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
