Catheter system having a push button needle retraction mechanism

Abstract

A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter. The catheter system may include a needle assembly, a barrel, an introducer needle comprising a sharp distal tip, a needle hub coupled to the introducer needle and movably disposed within the barrel, and a spring disposed within the barrel. The catheter system may include a push button disposed in a locked position such that depression of the push button is inhibited. The push button may be configured to slide laterally or distally from the locked position to an unlocked position. When the push button is in the unlocked position and the barrel is spaced apart from the catheter adapter, the push button may be configured to depress. In response to depression of the push button, the spring may be configured to expand proximally and move the needle hub proximally within the barrel.
