Abstract
Abstract An intravenous catheter assembly is constructed with a flexible plastic catheter for introduction into a body member and a flexible plastic tubing secured coaxially to the proximal end thereof by a wing section. An introducer needle extends completely through the coaxially aligned lumens of the catheter and tubing and a removable plastic sleeve having a longitudinal slit therein is positioned over the tubing between the wing section and the tubing hub to prevent displacement of the wing section toward the hub during the catheter introduction procedure.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
An intravenous catheter assembly, comprising: a flexible plastic catheter having a lumen extending therethrough; a flexible plastic tubing having a lumen extending therethrough in alignment with the lumen in said catheter; gripping means connected to the proximal end of said catheter and to the distal end of said tubing; a hub secured to the proximal end of said tubing; an introducer needle extending completely through said lumens from said hub to beyond the distal end of said catheter; and removable rigid support means disposed between said hub and said gripping means for positively preventing displacement of said gripping means toward said hub during the introduction of said needle and catheter into a patient.
Claim 2
Dependent Claim
113 words
