Abstract
An IV access device can include a needle hub that incorporates a flash chamber. The flash chamber can be used to provide visual confirmation of proper catheter placement within a vein. The flash chamber can include a path-defining structure to facilitate identifying whether blood is continually flowing into the flash chamber. The flash chamber may also be removable from the needle hub. In some cases, the needle hub may include a paddle grip that facilitates insertion of the catheter and separation of the needle hub from the catheter adapter.
Claims23
An IV access device comprising:
- a catheter adapter from which a catheter extends distally;
- an extension tube coupled to the catheter adapter;
- and
- a needle hub from which a needle extends distally, the needle hub being coupled to the catheter adapter such that the needle extends through the catheter;
- and
- a path-defining structure inserted into the flash chamber;
- wherein the needle hub further includes a flash chamber that is in fluid communication with a lumen of the needle thereby allowing blood to flow into the flash chamber into a path between the path-defining structure and the needle hub when a distal tip of the needle is contained within a patient's vein.
