Abstract
A skin microbiota modulation device that includes a cold plasma assembly configured to generate a cold plasma stimulus including a partially ionized gas mixture and to interrogate a biological surface with the cold plasma stimulus; and a microbiota seeding assembly including one or more target species of micobiota, the microbiota seeding assembly configured to deliver the one or more target species of micobiota to the biological surface.
Claims18
A skin microbiota modulation device, comprising:
- a cold plasma assembly configured to
- generate a cold plasma stimulus including a partially ionized gas mixture, and
- interrogate a biological surface having resident bacteria thereon with the cold plasma stimulus, the cold plasma stimulus being generated to eliminate the resident bacteria on the biological surface;
- and
- a bacteria seeding assembly including at least one replaceable cartridge including one or more reservoirs including one or more target species of bacteria, each reservoir of the one or more reservoirs being temperature-controlled, the bacteria seeding assembly configured to deliver the one or more target species of bacteria to the biological surface.
2 more elements
A method, comprising:
- performing a Cold Atmospheric Plasma (CAP) treatment to an external body part of a user having a resident bacteria thereon, the CAP treatment eliminating the resident bacteria from the body part;
- and
- applying a pre/pro or post biotic compound to the body part of the user following the CAP treatment via a bacteria seeding assembly including at least one replaceable cartridge including one or more reservoirs including one or more target species of bacteria, each reservoir of the one or more reservoirs being temperature-controlled, the bacteria seeding assembly configured to deliver the one or more target species of bacteria to the external body part of a user.
A system, comprising:
- a Cold Atmospheric Plasma (CAP) application device configured to perform a CAP treatment to an external body part of a user having resident bacteria thereon to eliminate the resident bacteria, the CAP application device including a bacteria seeding assembly including at least one replaceable cartridge including one or more reservoirs including one or more target species of bacteria, each reservoir of the one or more reservoirs being temperature-controlled, the bacteria seeding assembly configured to deliver the one or more target species of bacteria to the biological surface;
- and
- an applicator configured to apply a pre/pro or post biotic compound to the body part of the user following the CAP treatment.
