Abstract
A covered needle assembly having a needle member and a cover member pivotably connected to each other, the cover member having a long narrow opening for the needle to pass through when the cover member is pivoted away from the needle when ready for use, the opening being covered by a rupturable plastic film which breaks when the cover is pivoted to expose the needle.
Claims11
A throw-away covered needle for releasable attachment to a syringe having a short tubular inlet/exit pipe said covered needle consisting essentially of a needle member and a cover member;
- said needle member including a hollow needle with a free end and an encased end, said encased end being embedded in a head having a socket to receive said inlet/exit pipe, a passageway connecting said socket to the hollow of said needle, and two pivot pins projecting outwardly on opposite sides of said head generally perpendicular to the hollow of said needle;
- and said cover member being a semirigid elongated sheath enclosing said needle member and having passageways therethrough for attachment to said pivot pins, a lengthwise narrow opening extending from the top of said cover member to adjacent said free end of said needle and positioned to permit said needle to pass therethrough when said cover member is pivoted, and a rupturable plastic film covering said slot.
A safety covered needle for use on a medical syringe having a short tubular spout;
- said covered needle comprising a needle member and a cover member pivotally connected to said needle member;
- said needle member including cup-shaped head with an interior recess adapted to frictionally engage said spout, a hollow needle having a free end and having the other end embedded in said head, a passageway in said head joining said recess and said other end of said needle;
- and a pair of laterally extending pivot pins generally perpendicular to said needle;
- and said cover member being an elongated sheath having an upper open end and a lower closed end and a longitudinal axis corresponding to the hollow of said needle, a pair of eyes engageable with said pivot pins, an elongated narrow opening extending from an open end adjacent said eyes to a closed end adjacent said lower end of said sheath, and a ruptural plastic film covering all of said elongated narrow opening.
