Abstract

An intravenous catheter apparatus which protects a clinician from accidental puncture which may result in the transfer of dangerous infections. The catheter is introduced with the aid of a needle, which is thereafter withdrawn from the patient's body into a protective housing without exposing the needle during any intermediate stage of the process. Means are provided for latching the housing in place after needle withdrawal, and for unlocking a catheter hub is place after that time. Withdrawal and locking are effected in one continuous motion.
