Some medicaments, such as botulinum toxin, are sold in small glass vials with a cap that comprises a seal. The seal is punctured to allow liquid to be added to reconstitute the medicament, then allow the medicament to be withdrawn through a needle into a syringe. A substantially larger amount of a liquid medicament may be obtained by using an adaptor device. An adaptor device may have a puncture component that allows a flexible tube to be inserted through the seal at an angle that allows an end of a flexible tube to rest on the bottom on a vial around the edge of the vial. This may allow vial to be tipped so that the liquid pools around the end of the flexible tube, thus significantly increasing the amount of liquid that can be withdrawn.
