Needle shielding assemblies and infusion devices for use therewith
First Claim
1. A needle assembly, comprising:
- a needle having a sharpened end and an opposing end, the needle being insertable through a base; and
a needle shield device, comprising;
an inner shield connectable to at least one of the base and a fluid connector connectable to the base; and
an outer shield fixedly connected to the opposing end of the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield;
wherein during or after proximal displacement of the outer shield from the first position to the second position, interaction between portions of the inner and outer shields automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

Abstract
A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

17. A needle assembly, comprising:
-
a needle having a sharpened end and an opposing end, the needle being insertable through a base; and a needle shield device, comprising; an inner shield connectable to at least one of the base and a fluid connector connectable to the base; and an outer shield fixedly connected to the opposing end of the needle; wherein during or after the outer shield is proximally displaced relative to the inner shield by a predetermined distance, interaction between portions of the inner and outer shields causes automatic release or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

18. A method comprising:
-
providing a needle assembly, the needle assembly comprising; a needle with a sharpened end and an opposing end, the needle being insertable through a base; and a needle shield device, comprising; an inner shield connectable to at least one of the base and a fluid connector connectable to the base; and an outer shield fixedly connected to the opposing end of the needle; and displacing the outer shield by a predetermined distance relative to the inner shield, and, by interaction between portions of the inner and outer shields during or after the outer shield is proximally displaced, releasing the inner shield from connection to the at least one of the base and the fluid connector.

19. A needle assembly, comprising:
-
a needle having a sharpened end and an opposing end, the needle being insertable through a base; and a needle shield device, comprising; a first shield; and a second shield displaceable relative to the first shield between a first position, in which the sharpened end of the needle is exposed outside the first and second shields, and a second position, in which the sharpened end of the needle is shielded by the first and second shields; wherein one of the first and second shields is connectable to at least one of the base and a fluid connector connectable to the base; wherein one of the first and second shields is fixedly connected to the opposing end of the needle; and wherein during or after proximal displacement of the second shield from the first position to the second position, interaction between portions of the first and second shields automatically releases or permits release of the one of the first and second shields from connection to the at least one of the base and the fluid connector.
