In accordance with at least one exemplary embodiment, a syringe device, a method and a system for delivering a therapeutic amount of ozone are disclosed. A sterility case can enclose a syringe portion and can maintain sterility while the syringe device is interfaced to an ozone generator. A valvably-controlled fluid channel can extend from a barrel of the syringe portion through the case. Conducting elements can be attached to the case and can breach the case. The conductive elements can be connected to electrodes. The electrodes can be attached to the syringe portion. The syringe portion can be filled with oxygen gas via the valvably-controlled fluid channel. An electric current can be provided to the conductive elements from the ozone generator resulting in a corona discharge from at least one of the electrodes. The therapeutic amount of ozone can be produced from the oxygen gas and the syringe portion delivered into a sterile field without compromise.
