  • SYRINGE AND NEEDLE FOR PREVENTING INADVERTENT DRUG INJECTION
    Publication number: 20030018301
    Abstract: A spinal syringe and needle for preventing the inadvertent injection of an intravenous drug spinally includes a needle engagement extension on the spinal needle defining an opening of a first diameter, a syringe engagement extension on the spinal syringe defining an opening of a second diameter, the syringe engagement extension engageable with the needle engagement extension to operatively connect the needle to the syringe. The first and second diameters are dimensioned such that a surface of the syringe engagement extension is in frictional engagement with a surface of the needle engagement extension, the first diameter is substantially the same as the diameter of an opening defined by the engagement extension of a typical syringe and the second diameter is substantially the same as the diameter of an opening defined by the engagement extension of a typical needle.
