Abstract
A device and use method for ejecting a liquid stream towards an eye, the stream moving from a proximal position towards a distal position, the device comprising a) a housing, b) a container for the liquid, c) at least one opening arranged for ejection of the stream and being in fluid communication with the container, d) a pump mechanism operable to deliver at least part of the liquid from the container through the opening to form the stream and e) an eyecup with a contact surface arranged for contact with the eye or its facial surroundings. The eyecup is arranged movable with respect to the opening or housing between at least two positions i) an active position with said eyecup contact surface at a defined safety distance to the opening and ii) a rest position with the eyecup contact surface at a position more proximal than in the active position and a sensor is arranged to allow discrimination between the positions. The pump mechanism may include a pump driver able to store cocked energy for driving the pump mechanism and at least one activation mechanism may be present and operable to initiate the device for the liquid delivery, whereby a driving mechanism is arranged to transfor…
