Abstract
An enclosed needle catheter insertion device includes a catheter assembly and a need insertion device having a needle guard housing to enclose a needle in a shielded position and a needle support supporting the needle for movement between a ready position, with the tip of the needle exposed, to a shielded position with the needle within the needle guard housing. Movement of the needle support and the needle relative to the needle guard housing is accomplished by manual manipulation of a gripping component external of the needle guard housing. A separate, proximal end cap external of the needle guard housing encloses a proximal portion of the needle guard housing, and is affixed to the needle support.
Claims42
An enclosed needle device comprising:
- an elongated needle guard housing having a proximal end and a distal end;
- a needle support having an inner component movable within the needle guard housing between a first position adjacent the distal end of the needle guard housing and a second position adjacent the proximal end of the needle guard housing;
- a needle cannula affixed to and extending distally from the needle support for movement therewith and terminating in a sharp distal tip, the sharp tip of the needle being exposed out beyond the distal end of the needle guard housing in the first position of the needle support and the needle cannula being enclosed within the needle guard housing in the second position of the needle support;
- the needle support having an exposed gripping component external of the needle guard housing and attached to the needle support inner component within the needle guard housing such that manual manipulation of the gripping component results in movement of the needle support inner component, the gripping component being adjacent the distal end of the needle guard housing in the first position of the needle support and being sized to expose a substantial portion of the needle guard housing proximal of the gripping component in the first position of the needle support;
- and
- a proximal end cap external of the needle guard housing and being separate from and affixed to the needle support, the end cap being sized to receive therein and substantially enclose the portion of the needle guard housing proximal of the gripping component in the first position of the needle support.

A safety catheter device comprising:
- a catheter assembly including a catheter hub and a catheter tube extending distally from the catheter hub distal end;
- and
- an enclosed needle device coupled to the catheter assembly comprising:
- an elongated needle guard housing having a proximal end and a distal end;
- a needle support having an inner component movable within the needle guard housing between a first position adjacent the distal end of the needle guard housing and a second position adjacent the proximal end of the needle guard housing;
- a needle cannula affixed and extending distally from the needle support for movement therewith and terminating in a sharp distal tip, the sharp tip of the needle being exposed out beyond the distal end of the needle guard housing and the catheter tube in the first position of the needle support and the needle cannula being enclosed within the needle guard housing in the second position of the needle support;
- the needle support having an exposed gripping component external of the needle guard housing and attached to the needle support inner component within the needle guard housing such that manual manipulation of the gripping component results in movement of the needle support inner component, the gripping component being adjacent the distal end of the needle guard housing in the first position of the needle support and being sized to expose a substantial portion of the needle guard housing proximal of the gripping component in the first position of the needle support;
- and
- a proximal end cap external of the needle guard housing and being separate from and affixed to the needle support, the end cap being sized to receive therein and substantially enclose the portion of the needle guard housing proximal of the gripping component in the first position of the needle support.

A method of assembling an enclosed needle guard comprising:
- assembling a needle support with a needle extending therefrom for movement within a needle guard housing between a first position adjacent a distal end of the needle guard housing with a sharp distal tip of the needle being exposed out beyond the distal end of the needle guard housing and a second position adjacent the proximal end of the needle guard housing with the needle being enclosed within the needle guard housing, and a gripping component external of the needle guard housing for moving the needle support within the needle guard housing;
- and
- placing an end cap over a proximal end of the needle guard housing into confronting and abutting relationship with the needle support, and affixing the end cap and the needle support.
