Claim 5:
6. Method of using the assembly according to claim 1 for the reconstitution of fluid drugs and nutrients with active substances in powder, liquid or gel form, comprising the following sequence of steps:
a) coupling the coupling and piercing device to the vial containing the active substance in powder, liquid or gel form by piercing the hermetic closing cap by axial pressure;
b) connecting the coupling and piercing device to the second valve connector while the hermetic closing valve of the second valve connector is in a hermetically closed position;
c) screwing the first valve connector into the first end of the hollow external body of the adapter to open the hermetic closing valve of the first valve connector of the flexible bag previously filled with a dosed amount of the liquid solution;
d) applying an axial thrust to the second valve connector and screwing it into the first end of the hollow external body to open the hermetic closing valve of the second valve connector by the axially bored coaxial internal stem;
e) laterally compressing the flexible bag for the introduction of a part of the liquid solution into the vial through a fluid path formed by the first valve connector, the axially bored coaxial stem, the second valve connector, and the coupling and connecting device to obtain a desired fluid mixture of the active substance and the liquid solution;
f) placing upside down the assembly for the transfer of the desired fluid mixture from the vial to the flexible bag through the fluid path;
g) unscrewing the second valve connector from the first end of the hollow external body of the adapter to return the hermetic closing valve of the second valve connector to the hermetically closed position;
h) unscrewing the first valve connector from the first end of the hollow external body of the adapter to return the hermetic closing valve of the second connector to the hermetically closed position.
