ABSTRACT:
An intravenous catheter apparatus comprising an intravenous catheter tube, a manually guidable circumferentially deformable elastomeric bore-defining tubular inserter integral with and in axial alignment with the catheter tube for use with a patient, and a needle concentric within the catheter tube and inserter and extending through at least part of the bore of the inserter to beyond the distal end of the catheter tube, the inserter comprising opposed laterally extending wings adapted to be manually compressed together from an at-rest position to a needle control position, the bore of the inserter being sufficiently large to permit retraction of the needle from the catheter tube and the inserter when the inserter is at rest, and when the inserter wings are compressed to the needle control position being sufficiently constricted to enable the inserter to grip the needle firmly to permit inserter-forced injection of the distal end of the needle into the body of a patient.
