Abstract
A cannula or needle set for fluid flow connection with the vascular system of a patient. In one embodiment, the set comprises a hollow, hypodermic needle having a longitudinal axis and a sharp end for skin penetration and connection with the vascular system. A hollow hub carries the needle at a needle opposite to the sharp end. A fluid flow port is defined in the hub at a position laterally spaced from the axis of the needle. An injection site aperture is defined in the hub at a position centrally intersected by the needle axis, the injection site aperture being closed by a recloseable, needle-penetrable wall.
Claims9
A needle-containing set for fluid flow connection with the vascular system of a patient, which set comprises:
- a hollow hypodermic needle having a longitudinal axis and a sharp end for skin penetration and connection with the vascular system;
- a hollow hub which carries said needle at a needle end opposite to said sharp end;
- a fluid flow port defined in said hub a position laterally spaced from the axis of said needle, and communicating with the interior of said hollow hypodermic needle;
- and an injection site aperture defined in said hub at a position centrally intersected by said needle axis, said injection site aperture being closed by a recloseable needle-penetrable, resealable wall, further in which a substantially blunt rod or tube extends through said recloseable needle-penetrable wall and through said hollow needle to extend effectively beyond said sharp end, thus providing protection from accidental needle sticks.
A needle-containing set for fluid flow connection with the vascular system of a patient, which set comprises:
- a hollow, hypodermic needle having a longitudinal axis and sharp end for skin penetration and connection with a vascular system;
- a hollow hub which immovably carries said needle at a needle end opposite to said sharp end;
- a fluid flow port defined in said hub at a position laterally spaced from the axis of said needle, said fluid flow port communicating with the interior of said hollow hypodermic needle;
- and an injection site aperture defined in said hub at a position centrally intersected by said needle axis, said injection site aperture being closed by a recloseable, needle-penetrable, resealable wall, said fluid flow port being surrounded by a sleeve which is an integral part of said hub and which connects to a length of flexible tubing, said sleeve extending transversely to the needle axis, and a blunt rod or tube extending through said recloseable, needle-penetrable wall and through said hollow needle to extend at least effectively beyond said sharp end, thus providing protection from accidental needle sticks, said blunt rod or tube having a diameter to substantially fill the bore of said needle.
