Abstract
In accordance with at least one exemplary embodiment, a syringe, method and system for delivering a therapeutic amount of ozone are disclosed. An exemplary syringe can have a gas chamber and one or more electrodes. A portion of at least one electrode can be within the gas chamber. Alternatively, singularly or in conjunction, one or both electrodes can be attached to the outside of an exemplary syringe. One or more electrical contact points can be outside the gas chamber. Each electrical contact point can be connected to an electrode. Oxygen gas can provided within the gas chamber of the exemplary syringe. A medical ozone generator can be connected to the syringe via the electrical contact points. Corona discharge can be effectuated via the electrodes, which can result in an amount of ozone gas can being produced from the oxygen gas.
Core Innovation
The invention relates to a syringe gas chamber sized for oxygen gas, where corona discharge converts oxygen into ozone gas. An electrode arrangement is disposed on the syringe, including a foil electrode disposed on a surface of the syringe and at least one wire electrode attached to the syringe and extending at least partially into the gas chamber. The at least one wire electrode approaches a face of the foil electrode such that corona discharge can be effectuated from the at least one wire electrode to produce an amount of ozone gas from the oxygen gas.
The system further provides electrical contact points positioned outside the gas chamber to interface with a separate ozone conversion unit. Multiple electrode configurations are described for corona discharge, including arrangements with wire discharge electrodes and ground electrodes, a foil electrode with an opposed face near a wire electrode, single or multiple electrodes, and angled electrodes and dual opposing foil electrodes. These configurations support producing ozone on demand within the syringe gas chamber while positioning electrical interfaces outside the gas chamber.
A described ozone conversion unit uses high-voltage corona discharge and a UV absorption measurement assembly to select and/or verify ozone concentration, including UV absorption measurement techniques for determining ozone concentration. The document references UV light sources and detection components and describes selecting or verifying a therapeutic ozone concentration and accounting for factors such as nitrogen oxides (NOx) and leaks to address contamination and concentration control.
Claims Coverage
The provided independent claim describes 1 main inventive setup for producing ozone from oxygen using a syringe gas chamber with a specific foil-and-wire electrode corona discharge arrangement. Dependent claims add 2 additional inventive features: qualifying the produced ozone amount as therapeutic and measuring the concentration of the ozone produced.
Syringe gas chamber with foil and wire electrode corona discharge
Providing oxygen gas within a gas chamber of a syringe, disposing a foil electrode on a surface of the syringe, attaching at least one wire electrode to the syringe and extending the at least one wire electrode at least partially into the gas chamber such that the at least one wire electrode approaches a face of the foil electrode; effectuating a corona discharge from the at least one wire electrode; and producing an amount of ozone gas from the oxygen gas.
Therapeutic ozone amount
Using an amount of ozone gas that is a therapeutic amount.
Ozone concentration measurement
Measuring the concentration of the ozone gas produced.
Across the independent and dependent claims provided, the core claim centers on producing ozone on-demand from oxygen in a syringe gas chamber using corona discharge produced by a foil electrode and an inserted wire electrode that approaches a face of the foil electrode. The dependent claims narrow the ozone to a therapeutic amount and add measuring the concentration of the ozone produced.
Stated Advantages
Produces ozone directly from oxygen without substantial excess.
Reduces manufacturing cost by combining an ozone cell with a therapeutic delivery instrument.
Improves sterility/leakage considerations compared to reusable generator chambers.
Documented Applications
Autoinjection/therapeutic ozone uses are described in the background context.
