Harmonic Cold Plasma Devices and Associated Methods

摘要

A nozzle for attachment to a cold plasma device configured to maintain delivery of a stable cold plasma. The nozzle can have many different shaped apertures to support different applications requiring different shaped cold plasma plumes. Use of a disc of foam material within a nozzle can expand the size of aperture of a nozzle while maintaining delivery of a stable cold plasma. The nozzle can be an elongated cannula tube for internal delivery of a cold plasma treatment. The cannula tube can provide an aperture at its distal end or one or more apertures along its length. A shroud can partially enclose the distal aperture of the nozzle. A sterile sleeve can be used in conjunction with a nozzle to provide a sterile means of attachment and operation of the nozzle with a cold plasma device. In addition, various shaped apertures may be deployed to provide selective targeting of the cold plasma to a treatment area, while shielding other biological structures from cold plasma exposure. Such apertures also provide an opportunity for manual manipulation of tissues in the treatment area prior to or during cold plasma treatment.

主权项

1. A cold plasma application device, comprising:
a cold plasma generation device having a cold plasma outlet port; and a nozzle having a proximal aperture and a distal aperture, the proximal aperture configured to be coupled to the cold plasma outlet port, the distal aperture and a solid surface being located on opposing sides of the nozzle, wherein cold plasma is directed by the distal aperture to a treatment area, and wherein the solid surface precludes cold plasma from contacting a non-treatment area.
