A disposable cover for electromagnetic treatment applicators prevents undesired exposure to potentially harmful radiation. The cover is a pouch-like structure having a back surface constructed from RF shielding material, such as metallized polyethylene, which back surface faces opposite, or away from, the treatment area. A portion of the cover which faces the treatment area is constructed from material transmissive to RF radiation from the applicator. Securing means, such as adhesive strips, or interlocking edges close an open end to secure the applicator inside the cover and to prevent RF radiation through the closed end. In use, an applicator is inserted within the cover and positioned over the area to be treated with the RF transmissive material overlying the treatment area. When the applicator is activated, the generated electromagnetic energy exits the cover only through the RF transmissive material to the treatment area and the RF shielding material prevents exposure of the caregiver to potentially harmful radiation.

RF shielding cover for RF radiating applicator

A disposable cover for electromagnetic treatment applicators prevents undesired exposure to potentially harmful radiation. The cover is a pouch-like structure having a back surface constructed from shielding material, such as metallized polyethylene, which back surface faces opposite, or away from, the treatment area. At least a portion of the cover which faces the treatment area is constructed solely from RF non-shielding material. Securing means, such as adhesive strips, or interlocking edges, secure the applicator inside the cover and close off any leaks. The electromagnetic properties of the cover are integrated into the circuitry for the treatment applicator, such that the applicator is not functional in the absence of the cover. In use, an electromagnetic treatment applicator is inserted into the cover and positioned over the area to be treated with the non-shielding portion or window of the cover overlying the treatment area. Once assembled, the applicator/cover combination forms a closely matched and tuned network for effecting a highly efficient RF output. When activated, the generated electromagnetic energy only exits the cover through the RF non shielding portion or window, thereby preventing exposure of the patient or caregiver to potentially harmful radiation.

Disposable protective cover for RF treatment apparatus

An apparatus and method for the treatment of chronic wounds using electromagnetic energy. The apparatus includes a generator and at least one applicator. The generator can produce electromagnetic energy and the applicator can apply the electromagnetic energy produced by the generator. A detector is disposed on the applicator that can measure the field strength of the electromagnetic energy applied.

Pulsed electromagnetic energy treatment apparatus and method

A disposable cover for electromagnetic treatment applicators prevents undesired exposure to potentially harmful radiation. The cover is a pouch-like structure having a back surface (which faces opposite, or away from, the treatment area) constructed from shielding material, such as metallized polyethylene. At least a portion of the cover which faces the treatment area is constructed solely from non-shielding material. Adhesive strips, ZIP-LOCK&#xae;, or other interlocking edges, secure the applicator inside the cover and close off any leaks. The electromagnetic properties of the cover are integrated into the circuitry for the treatment applicator, such that the applicator is not functional in the absence of the cover. In use, an electromagnetic treatment applicator is inserted into the cover and positioned over the area to be treated, with the non-shielding, or 'window', portion of the cover overlying the treatment area. Once assembled, the applicator/cover combination forms a closely matched and tuned network for effecting a highly efficient RF output. When activated, the generated electromagnetic energy only exits the cover through the opening or 'window', thereby preventing exposure of the patient or caregiver to potentially harmful radiation.

A method of and apparatus for the treatment of chronic wounds using pulsed electromagnetic energy provides a constant, known and replicable dosage output which remains unaffected by the capacitance of the patient's body. The apparatus is simple to operate, requiring little operator training or interaction with the apparatus. All specifications of the apparatus relating to the generation and emission of electromagnetic energy are fixed, with the specifications based on actual scientific studies of the various technical parameters involved, such as pulse width and RF dosage. The apparatus includes a pulsed electromagnetic energy generator, a power level controller and one or more thin applicators which can be flexible. The applicators are located immediately adjacent to the patient's body, without the aid of a support member or removal of any dressings or bandages. The generator, which can be battery-operated, is a low power, programmable compact unit whose output is controlled by multiple control circuits for ensuring accurate treatment dosage, for confirming that the treatment was properly administered, and for disabling the generator when appropriate. The generator output is automatically adjusted in response to instructions from the field strength sensor located on or near the applicator. Multiple applicators selected to operate simultaneously at different treatment dosage levels are connected to the generator by multi-conductor cables and readily located directly on the treatment area. Each applicator is a pad including etched printed circuits. The circuits are matched and pre-tuned. An applicator-to-patient proximity detector is also incorporated in or on each applicator and connected to the generator via a power controller to provide for direct monitoring of the treatment site and precise control of treatment dosage.
