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.

主权项

1. A cold plasma device, comprising:
a housing having a high voltage electrical inlet port and a gas compartment, the gas compartment having a gas inlet port and a gas outlet port; an electrode disposed within the gas compartment, wherein the electrode is coupled to the high voltage electrical inlet port; anda nozzle having a proximal aperture and a distal aperture, the proximal aperture configured to be coupled to the gas outlet port, the nozzle configured to maintain a stable cold plasma plume exiting from the distal aperture, wherein the nozzle further comprises:
a disk positioned in the nozzle between the proximal aperture and the distal aperture the disk comprising, a material haying a plurality of sub-apertures embedded therein such that a stable cold plasma plume exits from the distal aperture.
