1. An intravenous (“IV”) catheter-placement device, comprising:
a cartridge including a barrel having a release button on a side of the barrel, a spring-loaded needle extending from a distal-end portion of the barrel, and an IV catheter including a catheter hub slidably disposed over the spring-loaded needle; and
a case fixedly disposed over the cartridge including a longitudinal slot in a side of the case, a deployment button configured to slide in a distal direction along the longitudinal slot and, in turn, slide the IV catheter over the spring-loaded needle and press the release button when the deployment button slides into the release button such that a spring compressed between a needle hub and the distal-end portion of the barrel is released and an entirety of the spring-loaded needle is launched into a needle cavity of the barrel.
