US Patent 7753338 Luer activated device with minimal fluid displacement

A luer activated device includes an inlet adapted to receive a male luer, an outlet associable with a fluid flow system, and a flow path defined therebetween. The inlet receives a resealable valve element having an aperture adapted to receive the male luer. The valve element is adapted such that a male luer inserted into the aperture will open fluid flow through the inlet without causing a substantial change in fluid displacement.
