The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet.

Additionally, the apparatus includes a fill assembly comprising a field fill vial that can be readily filled in the field.
