A medical spraying device and method, for irrigating a wound, having a liquid reservoir for a medical irrigation liquid or a connection for such a liquid reservoir and an arrangement for applying pressure to the medical irrigation liquid, such that the irrigation liquid is pushable through a nozzle by the pressure acting on the irrigation liquid in order to produce a spray cone. The nozzle has a plurality of openings, which are arranged at an angle to one another in such a way that the irrigation liquid jets exiting from the openings, at a such flow rate and angle, meet in an atomization space and/or a discharge opening of the nozzle； thus, a spray cone is produced from the atomized irrigation liquid.
