Abstract:
1. A safety catheter device comprising; a catheter hub having a proximal end and a distal end and an interior aspect therebetween; a catheter tube extending from the distal end of the catheter hub; a needle having a shaft terminating in a distal sharp tip; a housing having a proximal end and a distal end, the housing being removably coupled to the catheter hub; and a member having a proximal end with an aperture and a distal end, the member being disposed distal of the housing proximal end and proximal of the catheter tube, the housing and the member adapted to slidably receive the needle therethrough between (a) a first position with the needle shaft extending through the aperture of the member and distally of the member distal end through the catheter tube with the needle distal tip exposed out therefrom and the member distal end bearing against the needle shaft, and (b) a second position with the needle shaft removed from the catheter tube, the needle distal tip disposed within the housing proximal of the housing distal end and proximal of the member distal end, and with the needle shaft extending through the aperture of the member, the member distal end being proximal of the housing distal end with the needle in the second position and being operable to maintain the needle distal tip within the housing after the needle has moved from the first position to the second position; the housing including a radially outwardly directed projection and a support being positioned radially inwardly of the projection and extending proximally thereof, the projection being operable to engage the interior aspect of the catheter hub and radially moveable inwardly sufficiently to disengage therefrom, the projection being held against moving radially inwardly sufficiently to disengage when the needle is in the first position and being free to move radially inwardly sufficiently to disengage coincident with the needle being moved into the second position, the housing defining a passageway portion starting at a distal-most end of the housing and extending proximally along the support, the passageway portion being distal of the needle in the second position, no part of the housing defining the passageway portion being in direct contact with the needle in the first position.
