Flush enhancing male luer tip design for syringes and any luer connector

摘要

A luer connection device is disclosed having a housing including a side wall having an inside surface defining a lumen with a central axis, a proximal end, and a distal end including a male luer tip having a central flow diverter extending outwardly from the central axis of the lumen to direct a fluid to a circumferential dead space distal to the male luer tip. A luer connection device is also disclosed having a flow expansion channel disposed in the lumen tapering outward from the wall of tubular housing and partially extending along a longitudinal axis from the tip opening toward the base opening for increasing mixing and flow through a circumferential dead space in the fluid path distal to the male luer tip.

1. A luer connection device comprising:
a housing including a side wall having an inside surface defining a lumen with a central axis, a proximal end, and a distal end including a male luer tip having a passageway therethrough providing fluid communication between the proximal end and the distal end; said male luer tip disposed at the distal end having a central flow diverter extending outwardly from the central axis of the lumen to direct a fluid to a circumferential dead space located distal to the male luer tip; and at least one flow expansion channel located in the interior of the lumen, the at least one flow expansion channel extending longitudinally along the length of the lumen to the male luer tip, the at least one flow expansion channel is connected to the central flow diverter to allow fluid communication between the at least one flow expansion channel and the central flow diverter, the at least one flow expansion channel directs fluid flow into the central flow diverter.
