Abstract:
1. A device for preparing and/or administering by mucosal administration a very small volume of an alcohol based solution containing at least a lipophilic active principle, the device comprising a head and a container, the head being suitable for taking up a first conservation position P 1 in which said head is in a distal position relative to the container, and a second administration, position P 2 in which said head is in a proximal position relative to the container, said head including a cannula with at least one flow channel, the flow channel having a length permitting the free end of the flow channel to deliver the solution by sublingual and/or paragingival permeation while the device is being held in the hand; said device comprising at least two compartments, each compartment separated by a leakproof barrier, each compartment containing at least one or more of an active principle, an excipient, an antigen substance, and a solvent, said device further comprising perforation means for perforating the leakproof barrier; said perforation means formed on the cannula and in contiguity with the compartments so as to enable the substances contained in said compartments to be mixed together in a determined order; wherein the head includes one or more of an active principle, an antigen substance, an excipient, and a solvent; and wherein, prior to the perforation means perforating the leakproof barrier, the one or more of the active principle, the antigen substance, the excipient, and the solvent are contained in a space defined at least in part by a wall within the head that moves with the head during at least an initial part of a displacement of the head from the conservation position to the administration position.
