Abstract
A safety needle device and method of supplying fluid to a vascular access port is described. The device may include a base member, a handle member, and a compressible member positioned between the handle member and a compression plate. The compressible member is coupled to a proximal end of a needle. Following the delivery of fluid to a vascular access port, the needle is removed by moving the handle member away from the base member, which collapses the compressible member, flushing fluid into the vascular access port to substantially replace a volume of the needle.
