  • Minimizing Resistance to Catheter Advancement During Vascular Cannulation
    Publication number: 20130274713
    Abstract: A hypodermic needle minimizing resistance to catheter advancement during vascular cannulation includes a needle shaft and a needle tip including an open needle bevel extending along middle and proximal portions of the open bevel until a distal end of the needle shaft, wherein a most distal portion of the open bevel is filled to prevent flashback. The hypodermic needle also includes a catheter overlying the needle shaft in the resting position.
    Type: Application

  • Methods of minimizing disease transmission by used hypodermic needles, and hypodermic needles adapted for carrying out the method
    Patent number: 5478328
    Abstract: A needle, related attachments, and methods of constructing and using the same, for reducing the risk of infection from material in a used hypodermic needle. The needle is formed with a solid tip having no orifice, at a distal end of the needle. At least one longitudinal bore is formed in the needle which terminates proximal to the needle tip. At least one outlet orifice is formed in communication with the bore, for passage of all material into or out of the needle, the outlet orifice being located at a lateral position spaced back from the solid tip, thereby reducing the risk that an individual who contacts the tip of the needle will contact material retained in the needle.
