Ocular micro-inhaler comprising a vacuum pump, connected to a handpiece (e.g. canula), and a pedal control member actuating a pressure-reduction regulator RG which consists on the one hand of a cylinder CY formed by a channel in two parts (channels CA1-CA2) of the same diameter and separated by a chamber CB which is open to the atmosphere, and on the other hand of a piston PS which can slide in the channels by virtue of a kinematic transmission controlled by the inclination of the pedal, the said piston having a conical head PST. <IMAGE>
