Abstract

A system for treating, in particular cleansing, wounds with a fluid jet. The system includes a handpiece with a main body with a front end with an emergence opening for the emergence of the fluid jet. The system furthermore has at least one light-emitting light source, which irradiates aerosols created when cleansing the wound. The system enables wound cleansing with simultaneous decontamination of the aerosols created in the process such that the risk of contamination of the surroundings is reduced and preferably with simultaneously treating the wound with UV light.

Core Innovation

The invention relates to a wound-treatment or wound-cleansing system that uses a fluid jet handpiece. The system provides a UV-C light source arranged so that emitted UV-C light surrounds an emerging micro/high-pressure fluid jet, forming light cones that substantially completely envelop the jet region, in particular the region where aerosols are created during cleansing.

The UV-C light is used to irradiate and decontaminate aerosols created when cleansing a wound during a cleansing process by means of the fluid jet. A toroidal front part of the UV-C light source is provided such that it completely surrounds the fluid jet, enabling the aerosols located within the light cone to be irradiated and decontaminated.

The disclosed approach is configured to reduce a risk of contamination of surroundings while performing wound cleansing with the fluid jet. The document describes front-end embodiments for arranging the UV-C light source relative to the fluid jet, including configurations in which UV-C sources are positioned centrally or in recessed/flush/protruding arrangements, and light-cone shapes including round, pyramid, cone, and toroidal forms.

Claims Coverage

The independent claim covers a wound-treating method using a fluid jet combined with a UV-C light source configured to surround the jet and decontaminate aerosols within a formed light cone. The claim includes a toroidal UV-C front part and a light cone that completely envelops the fluid jet to reduce contamination of surroundings, with additional narrowing by a dependent claim to cleaning wounds specifically.

Overall claim coverage centers on wound cleansing with a specified micro/high-pressure fluid jet combined with UV-C irradiation configured to decontaminate aerosols by a UV-C toroidal front part that surrounds the jet and forms a light cone that completely envelops the jet region to reduce contamination of surroundings.
