The invention relates to a medical spraying device for irrigating a wound, in particular lavage system, comprising a liquid reservoir for a medical irrigation liquid or a connection for such a liquid reservoir and a compressed gas reservoir, wherein the compressed gas reservoir is connected or connectable via a pressure line to the liquid reservoir, such that the irrigation liquid can be pushed by the gas pressure of the compressed gas reservoir acting on the irrigation liquid through a nozzle in order to produce a spray cone, wherein a pressure reduction valve is arranged in the pressure line and limits the gas pressure acting in the liquid reservoir on the irrigation liquid. The invention also relates to the use of such a medical spraying device for producing a spray cone for debriding infected tissue and to a method for producing a spray cone of a medical irrigation liquid, in particular using such a spraying device, in which a gas pressure is limited using a pressure reduction valve, the gas pressure limited by the pressure reduction valve is conveyed through a pressure line to a liquid reservoir of the medical irrigation liquid, and the irrigation liquid is pushed out from the liquid reservoir through a nozzle by means of the gas pressure, wherein the spray cone is produced in that the irrigation liquid flows through the nozzle. |
