Intravenous catheter-placement device and method thereof

An intravenous (“IV”) catheter-placement device, comprising:

• a cartridge including:
• a barrel including a needle cavity, a spring compressed against a distal-end portion of the needle cavity in at least an initial state of the IV catheter-placement device, and a release button on a side of the barrel configured to release the spring when the spring is compressed;
• a needle extending from the barrel, the needle including a needle hub captively disposed in the needle cavity compressing the spring against the distal-end portion of the needle cavity in at least the initial state of the IV catheter-placement device;
• and
• an IV catheter including a catheter hub slidably disposed over the 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 needle and press the release button when the deployment button slides into the release button such that the spring is released and an entirety of the needle is launched into the needle cavity for a deployed state of the IV catheter-placement device.

A method of using an intravenous (“IV”) catheter-placement device, comprising:

• obtaining the IV catheter-placement device, the IV catheter-placement device including:
• 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;
• piercing a vein of a patient with the spring-loaded needle;
• sliding the IV catheter over the needle and into the vein by way of the deployment button;
• and
• pressing the release button when the deployment button slides into the release button, thereby launching an entirety of the needle into a needle cavity of the barrel by releasing a spring compressed against a distal-end portion of the needle cavity by a needle hub of the spring-loaded needle.
