Abstract
Disclosed is a single-use syringe comprising a needle housing, a bore-containing fluid-delivery needle and a volume-containing element. The needle housing has a top surface to which the volume-containing element is attached, a needle attachment side to which the bore-containing needle is attached, and a fluid delivery channel in communication between the top surface and the needle attachment side. The volume-containing element is fluid-tight but for communication with the fluid-delivery and a filling port. Embodiments are disclosed which include vapor-permeable portions which facilitate lyophilization of materials in situ.
