1. An intravenous therapy system, comprising:
a housing to house an actuation hub, the actuation hub comprising:
a needle hub operatively coupled to a needle to insert the needle into a body of the patient; and
a catheter hub fluidically coupled to a catheter to insert the catheter into the body, the catheter being formed coaxially with an outer surface of the needle;
an inflatable bladder formed along a length of the catheter to maintain the catheter in the body; and
a fluidic channel in fluid communication with both the inflatable bladder and the catheter hub such that the fluidic channel is configured for inflation of the inflatable bladder with a first fluid and infusion of a second fluid into a blood stream of the patient, wherein the first fluid and the second fluid are the same fluid;
wherein after insertion of the needle into the body, the needle is configured to be retracted into the needle hub, thus maintaining a distal end of the needle within the needle hub, to coaxially remove the needle from within the catheter, wherein after insertion of the needle into the body, the needle is configured to be retracted into the needle hub such that the needle does not interfere with the flow of fluid through the fluidic channel to the inflatable bladder and the catheter hub but also maintains a seal to prevent leakage out of the catheter or the fluidic channel.
