Abstract
Extended dwell catheter assembly allows for one-handed operation by a physician such that the physician may continue to operate a visualization tool with the other hand throughout the catheterization process using the extended dwell catheter assembly. The catheter assembly can have stacked push tags to prevent false activations and to provide a manipulation means in the correct order of actuation.
Claims18
1-15. (canceled)
A catheter assembly comprising:
- a housing having spaced apart walls;
- a catheter hub located within the housing;
- a catheter tube coupled to the catheter hub, the catheter tube defining a catheter axis;
- a needle projecting through the catheter tube;
- and
- a catheter activation device comprising a first push tag having a surface for pushing to move the catheter hub relative to the housing and a second push tag having a surface for pushing to move the catheter hub relative to the housing,
- wherein the first and second push tags are movable with one another to move the catheter hub from a first position to a second position within the housing and the first and second push tags are movable relative to one another for moving the catheter hub from the second position to a third position;
- and
- wherein the first and second push tags are spaced from one another a first distance in the first position and are spaced from one another a second distance in the second position, which is less than the first distance.
6 more elements
A method of assembling a catheter assembly, the method comprising:
- assembling a catheter activation device comprising a first push tag having a surface and a second push tag having a surface to a housing, said housing having spaced apart sidewalls;
- placing a catheter hub in sliding communication with the first push tag and the second push tag;
- coupling a catheter tube to the catheter hub;
- projecting a needle through the catheter tube;
- and
- wherein the first push tag and the second push tag are movable with one another to move the catheter hub from a first position to a second position and the first push tag and the second push tag are movable relative to one another to move the catheter hub from the second position to a third position.
