Abstract:
1. A medication delivery apparatus comprising: an antistatic holding chamber comprising a material having a surface resistivity that reduces a risk of resistance to medicament flow, wherein said holding chamber has an input end and an output end spaced apart along a longitudinal axis; a patient interface component connected to said output end and comprising an interior surface defining a flow passage; and a one-way valve disposed adjacent said output end, said one-way valve moveable between an open position and a closed position, wherein said one-way valve has a central opening when in said open position, said central opening having a flow path along said longitudinal axis, wherein no portion of said interior surface of said patient interface component downstream of said one-way valve intersects said flow path in an orthogonal relationship, so as to facilitate an unobstructed flow from the antistatic holding chamber to a patient.
