摘要： An apparatus to automatically secure an end of a needle after contact with a blood vessel. The apparatus may include a housing and a biasing member, where the housing includes a hollow interior region extending between a proximal end and a distal end thereof. A proximal opening may be integrated into the proximal end, while a distal opening may be integrated into the distal end. The proximal and distal openings may be configured to receive a needle therethrough along a longitudinal axis. The biasing member may be coupled to the housing and configured to apply a force to the needle. The force may be oriented to displace the needle relative to the longitudinal axis upon retracting an end of the needle through the distal opening into the hollow interior region. Embodiments of the present invention may thus secure the end of the needle within the hollow interior region after use to prevent accidental needle sticks and exposure to blood and blood-borne pathogens.

摘要： A system for controlling fluid flow in a catheter assembly is disclosed. The system comprises an intravenous catheter assembly with a catheter adapter. The catheter adapter comprises an inner lumen with a septum disposed within a portion of the inner lumen. The septum has a barrier capable of being deformed from a relaxed position to a biased position. The barrier further comprises a slit having a closed configuration and an opened configuration. The slit is in the closed configuration when the barrier is in the relaxed position and in the opened configuration when the barrier is in the biased position. The barrier is configured to be mechanically deformed from the relaxed position to the biased position by a septum actuator that advances against a proximal surface of the barrier without traversing the barrier.
