Abstract:
A cold plasma mask application device for delivery of a cold plasma to the face of a patient. An appropriate gas is introduced into a gas containment area that is energized by one or more electrodes that receive energy from a pulsed source. The plasma can be prevented from contact with the patient's face, or can be allowed to make contact with the patient's face at the appropriate treatment area. A three-layer approach to the manufacture of the cold plasma mask application device is also described. Such a device and method can be used to treat acne as well as complex facial wounds such as those resulting from trauma, melanoma, and other cancers of the face, rosacea, and psoriasis.
Abstract:
A method for monitoring pressure at one or more points on an individual, and automatically adjusting one or more sections of a support structure. The method includes periodically receiving pressure data from one or more radio frequency addressable sensors placed on an individual; determining, based on the received pressure data, whether an adjustment in the support structure is required; systematically adjusting cells located within the plurality of zones, one zone at a time, until an improvement in pressure data is indicated, if an improvement in pressure data is indicated for a zone, systematically adjusting cells within the plurality of subzones for that zone, one subzone at a time, until an improvement in pressure data is indicated. if an improvement in pressure data is indicated for a subzone, systematically adjusting cells in that subzone, one cell at a time, until an improvement in pressure data is indicated.
Abstract:
A cold plasma sterilization device for sterilization of objects such as medical instruments. Gas is fed to a plasma chamber where it is energized by one or more electrodes coupled to a pulse source to thereby generate a cold plasma inside the plasma chamber. A dielectric barrier is sandwiched between the gas compartment and the electrodes to form a dielectric barrier discharge device, inside the plasma chamber, one or more conductive stands that are coupled to ground hold the object to-be-sterilized. The cold plasma exits the plasma chamber, where it is recirculated for further use as a plasma source in subsequent cycles. Gases that can be used include noble gases such as helium, or combinations of noble gases.
Abstract:
A cold plasma treatment device for delivery of a cold plasma to patient treatment area. Gas is fed to a gas compartment where it is energized by an electrode coupled to a pulse source to thereby generate a cold plasma. A dielectric barrier is sandwiched between the gas compartment and the electrode to form a dielectric barrier discharge device. The cold plasma exits the gas compartment via a bottom member having a plurality of holes. Gases that can be used include noble gases such as helium or combinations of noble gases.
Abstract:
A gas cartridge is described that is configured to provide sufficient gas to support cold plasma generation for a specific medical process. The gas cartridge has a seal that is pierced upon connection of the gas cartridge to the cold plasma delivery system. Different embodiments are described that use different connection locations between the gas cartridge and the cold plasma delivery system. A shroud is also described that shields the user if the cold plasma delivery system is dropped and the gas cartridge ruptures. Use of an ID system assists in ensuring that the correct gas mixture, correct gas cartridge and correct power supply settings are used for the particular medical treatment process.

Abstract:
An inhalable cold plasma mask device for generation of a breathable cold plasma for delivery to a patient. A biocompatible gas is received in a dielectric barrier discharge (DBD) device that is energized by an electrode that receives energy from a pulsed source. The DBD device can be grounded by a grounding structure. A grounding screen can be used prior to inhalation of the cold plasma. The inhalable cold plasma mask device includes the use of a single-layer or a two-layer approach to its construction. The inhalable cold plasma mask device can have one or two DBD devices. Such a device and associated method can be used to treat upper respiratory tract infections, as well as reducing inflammation, sinus and esophageal polyps in both size and frequency of occurrence.
Abstract:
Embodiments of a compartment monitor that can be implanted and left in situ to continuously (or semi-continuously) measure compartment pressures are presented. An exemplary monitor includes a pressure sensor adapted to be implanted in a compartment, a transmitter external to the compartment and coupled to the pressure sensor, and a receiver in communication with the transmitter to receive and process pressure data received from the transmitter. The monitor may also be configured to transmit measured pressure data to a networkable device. The networkable device can then communicate the patient's status and condition to a healthcare provider through a local area network (LAN) or wide area network (WAN). This communication allows the healthcare provider to remotely monitor a patient. The networkable device, or associated computing system, can record and display trends in the pressure data over time, and log the data to the patient's electronic health records.
Abstract:
A cold plasma device for killing or reducing a microbiological pathogen, or denaturing a protein in food, in a food processing system using a cold plasma device. The cold plasma device directs a cold plasma at food or a food surface over an effective area for an effective amount of time. The cold plasma device can be a DBD electrode device, or an array of DBD electrode devices. A grounding rod assembly is also described.
Abstract:
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.
