MEDICAL SPRAYING DEVICE WITH NOZZLE, AND METHOD FOR PRODUCING A SPRAY CONE

摘要

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 atomisation space and/or a discharge opening of the nozzle; thus, a spray cone is produced from the atomised irrigation liquid.

主权项

1. A medical spraying device for irrigating a wound comprising a liquid reservoir (16) for a medical irrigation liquid (18) or a connection for such a liquid reservoir (16) and an arrangement for applying pressure to the medical irrigation liquid (18), such that the irrigation liquid (18) is pushable through a nozzle (24, 52) by the pressure acting on the irrigation liquid (18) to produce a spray cone (58), wherein the nozzle (24, 52) has a plurality of openings, that are arranged at an angle to one another such that irrigation liquid jets exiting from the openings meet in an atomisation space (38, 57) or a discharge opening of the nozzle (24, 52) and produce the spray cone (58) from the atomised irrigation liquid (18).
