  • Patent number: 6517521
    Abstract: An improved hypodermic needle that greatly reduces the pain associated with injection through the skin that includes a translucent hub for quick observation of flashback, a regular-wall needle with multiple strategically-placed lateral perforations ending with a blade-like honed edge orifice which the remainder of the injection fluid escapes. The increase in localized surface area through which fluid leaves the needle decreases the mechanical distortion of the surrounding tissue thereby lessening pain receptor stimulation and reducing the perception of pain during the injection process.
