Abstract

The present disclosure relates to a medicament delivery device comprising a medicament receiving element, at least one fluid chamber having a fluid outlet configured to direct fluid vapour towards the medicament receiving element, a heating element for heating the fluid in the at least one fluid chamber. The device is configured such that, in use, the heating element heats the fluid in the at least one fluid chamber to at least partially evaporate the fluid so that the vapor pressure in the at least one fluid chamber increases until the fluid is expelled out of the at least one fluid chamber through the fluid outlet towards the medicament receiving element and entrains the medicament towards the patient's skin.
