ABSTRACT:
A catheter insertion device with an automatic safety barrier includes a housing, a barrier member, and a biasing element. The housing includes a central bore configured to receive a needle therethrough, and further includes a channel extending through the housing and intersecting the central bore. The barrier member is hingedly coupled to the housing, and includes a leg to extend through the channel. An opening in the leg substantially aligns with the central bore to accommodate the needle therethrough. The biasing element biases the barrier member relative to the housing such that withdrawing the needle through the opening causes the biasing element to misalign the opening with the central bore, thereby occluding the central bore to shield an end of the needle.
