Device applies electromagnetic energy (27.12 MHz) to generate deep tissue heat for therapeutic purposes. System comprises power supply, RF oscillator, power amplifier, and output resonant tank. Clinician selects capacitive or inductive electrodes (various sizes/types) to deliver energy. Output intensity and tuning controls manage energy transfer; power output meter monitors current draw. Dosage determined by patient sensation (Dose I-IV). Used in clinical settings by healthcare providers to treat pain, muscle spasms, and joint stiffness. Benefits include increased blood flow and reduction of inflammatory conditions. Device does not treat malignancies.

Clinical Evidence

Bench testing only. Device performance verified through compliance with recognized consensus standards including UL 60601-1 and IEC 60601-1-2. No clinical data provided.

Technological Characteristics

Shortwave diathermy device operating at 27.12 MHz. Components: RF oscillator, power amplifier, resonant tank. Accessories: capacitive electrodes (round, flexible rubber) and inductive electrodes (monode, diplode). Standards: UL 60601-1, IEC 60601-1-2, IEC 60601-1-4. Energy source: electrical power supply. Form factor: clinical console with manual intensity and tuning controls.

Indications for Use

Indicated for patients requiring therapeutic deep heat for musculoskeletal disorders, muscle spasms, joint stiffness, contractures, and chronic inflammatory or infective conditions including tenosynovitis, bursitis, synovitis, and chronic inflammatory pelvic diseases. Contraindicated for the treatment of malignancies.

Regulatory Classification

Identification

A nonthermal shortwave therapy is a prescription device that applies to the body pulsed electromagnetic energy in the RF bands of 13.56 MHz or 27.12 MHz and that is intended for adjunctive use in the palliative treatment of postoperative pain and edema of soft tissue by means other than the generation of deep heat within body tissues as described in paragraph (a) of this section.

# Intended Use:

Intelect® SWD 100/ Senior Solutions® Shortwave Diathermy device for use in applying therapeutic deep heat for selected medical conditions by applying electromagnetic energy in the radio frequency band of 27.12 megahertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies.

# Description :

The Intelect® SWD 100/ Senior Shortwave Diathermy devices consists of a power supply that provides power to a radio frequency oscillator. This radio frequency oscillator provides stable, drift-free oscillations at the required frequency. The power amplifier generates the power required to drive the different types of electrodes. The output resonant tank tunes in the patient as part of the circuit and allows maximum power to be transferred to the patient.

The output intensity controls the percentage of maximum power transferred to the patient circuit. The tuning control adjusts the output circuit for maximum energy transfer from the radio frequency oscillator. The power output meter monitors only the current that is drawn from the power supply and not the energy being delivered to the patient.

The power output produces sufficient energy to raise the tissue temperature into a therapeutic range. The specific absorption rate (SAR) represents the rate of energy absorbed per unit area of tissue mass.

Patient sensation provides the basis for recommendations of continuous shortwave diathermy dosage and thus varies considerably with different patients. The following are recommended dosage guidelines: Dose I (lowest): No sensation of heat

Dose II (low): Mild heating sensation

Dose III (medium): Moderate (pleasant) heating sensation

Dose IV (heavy): Vigorous heating that is tolerable below the pain threshold

Therapy may be delivered to the patient via either capacitance or induction techniques. The Intelect® SWD 100/ Senior Solutions® Shortwave Diathermy devices use the following accessories:

- Capacitive Electrodes
- Pair of 80mm round
- Pair of 120mm round
- Pair of 165mm round
- 180mm x 120mm flexible rubber electrodes
- 250mm x 145mm flexible rubber electrodes
- Inductive Electrodes
- Monode 14cm
- Diplode 18cm x 39cm

Each of these techniques can affect different biological tissues, therefore selection of the appropriate electrodes is essential for effective treatment.
