•

handling of the accessories may adversely affect their characteristics. Inspect cables, electrodes, associated connectors, and accessories

•

before each use. To test the Patient Interrupt Cord, follow the procedures listed in "Testing the Patient Interrupt Cord" on page 15.

Ext

ernal conductive material should be removed from the

•

immediate treatment area. Do not use accessories other than those supplied with the unit, or

•

recommended by Chattanooga Group. The safety of other products has not been established, and their use could result in injury to the patient and degrade minimum safety.

Disconnect the Power Supply Cord before removing covers on this

•

equipment. This equipment has an output that is capable of producing a

•

physiological effect. Grounding reliability can only be achieved when the equipment

•

is connected to an equivalent receptacle marked "Hospital Only," "Hospital Grade," or a receptacle otherwise properly grounded.

Medical electrical equipment needs special precautions regarding

•

EMC and needs to be installed and put into service according to the EMC information provided in the User Manual.

This unit generates, uses, and can radiate radio frequency energy

•

and, if not installed and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity. However, there is no guarantee that interference will not occur in a particular installation. Harmful interference to other devices can be determined by turning this equipment on and increasing the output. Try to correct the interference using one or more of the following: reorient or relocate the receiving device, increase the separation between the equipment, connect the equipment to an outlet on a different circuit from that to which the other device(s) are connected.

SAFETY INSTRUCTIONS

Shortwave Diathermy

To determine the distance of separation for all equipment operating • near the unit, consult the EMC tables (listed in Appendix A of the User Manual) applicable to the other equipment. If the distance cannot be determined, make certain that the other equipment is operated from a distance of no less than 12 meters.

This equipment is to be used by, and sold to, a trained clinician only

•

under the prescription and supervision of a licensed practitioner.

Since • relatively high powers are used, there is the possibility of producing shock, localized burns, and cataracts if the patient is unaware of the heat due to reduced thermal sensation, or if the patient does not know what to expect during treatment.

Improper installation, operation, or maintenance of the shortwave

•

diathermy system may result in malfunctions of this unit or other devices.

In case of Display Assembly failure or other obvious defects,

•

switch the unit off immediately by means of the power switch and disconnect the power cord from the power outlet.

Be aware that some synthetics and plastics, though assumed to be

•

non-conductive, may be heated by shortwave diathermy. Adjustments or replacement of components may result in the

•

equipment failing to meet the requirements for interference suppression.

If the unit cannot be installed immediately after delivery, the unit

•

and its external components or accessory elements must be stored in their original packaging in a dry place.

Do not store or operate the unit in a dusty environment.

•

Keep all electrodes, accessories, and their cords separated during • treatment by using the cable clips located on the side of the arm extenders. Electrodes or their cords in contact with each other during treatment could result in improper stimulation, skin burns, or damage to the cord or electrode.

Do not lean on or hold the cables during operation.

•

Keep all line cords away from the diathermy unit cables. Do not • store or coil line cords where they can come close to the cables on an operating shortwave diathermy unit.

This equipment is not designed to prevent the ingress of water

SAFETY INSTRUCTIONS

Shortwave Diathermy

Do• not administer shortwave diathermy to a patient who has had an implant in the past unless you are absolutely certain that the implant and all leads in their entirety have been removed. Note that the leads are often left implanted after the implant is removed.

This unit generates non-ionizing radiation. Patients with

•

implanted electronic devices, such as cardiac pacemakers and defibrillators, cochlear implants, bone growth stimulators, deep brain stimulators, spinal cord stimulators, and other nerve stimulators, must not be treated, even if the device has been turned off.

The function of certain implanted devices (e.g.,

•

pacemakers) may be adversely affected during treatment with shortwave diathermy. In case of doubt, the advice of a licensed practitioner in charge of the patient should be sought.

Service Personnel, Technicians, and non-service personnel

•

who have any metallic implants, any implanted system containing leads, or who have had an implant in the past should not service this unit.

Technicians without the proper equipment and/or training

•

should not test the power output of this unit using a power meter.

Pins 3 and 4 (P100) on the RF Generator Assembly (see

•

page 8) or Variable Power Supply can carry electrical

charge. Before attempting to service the unit, discharge pins 3 and 4 to ground through an 100 Ohm 5 W resistor.

The mode of operation poses the risk of tissue destruction

•

and/or death. Shortwave diathermy should not be used on patients who

•

have any implanted metallic lead or any implanted system that may contain a lead. Both the heating and non-heating modes of operation pose a risk of tissue destruction. If you are a licensed practitioner who implants or monitors patients with leads or implanted systems with leads, explain to the patient what diathermy is and stress that they should not receive shortwave diathermy treatment. If you are a licensed practitioner who uses diathermy in your practice, be sure to ask patients about possible implants before deciding to administer shortwave diathermy.

Other equipment, including patient connected devices,

•

may be adversely affected when in close proximity to shortwave diathermy equipment.

Patients should not be treated with shortwave diathermy

•

when they have reduced thermal sensitivity over the proposed area of treatment, unless the physician in charge of the patient is notified.

Treatment should not be given through clothing, although

•

it is permissible to administer treatment through a dressing or plaster in pulsed modes.

Remove hearing aids prior to treatment.• At average power levels above 5 W, patients should •

not be allowed to come into contact with conductive parts which are earthed or which have an appreciable capacitance to earth and which may provide unwanted pathways for the radio frequency current. In particular, treatment must never be given with the patient on metal framed couches, chairs, or beds. Do not use conductive mattresses or mattress covers.

Before increasing the output in response to a report

•

of inadequate patient heating, verify that the cables are properly routed, spaced correctly, and away from metal or grounded objects. The heating effect may be misdirected and heating may be occurring in an unwanted area.

Before each use, check the condition of the housing and

•

the insulation of the electrodes, electrode connection cable, and the Power Supply cable. Also make sure that the cables have been routed correctly.

If the unit is not

• safe for operation, then it must be

repaired by certified service personnel and the operators must be informed of the dangers posed by the unit.

In order to prevent electrical shock, unplug the power

•

plug from the socket before cleaning or disinfecting the unit.

Under no circumstances may liquid penetrate the

•

openings on the unit, e.g. the connecting sockets of the electrode cables. Therefore, do not use cleaning or disinfectant sprays.

The unit, electrodes, and cables may not be sterilized

•

using steam or gas. Never clean the unit with abrasives, disinfectants or

•

solvents that could scratch the housing or damage the unit.

Internal burns can occur with the incorrect application of

•

shortwave diathermy due to excessive intensity. Internal burns can occur with the incorrect application of

•

shortwave diathermy due to excessive exposure time. Do not perform unauthorized repairs under any

•

circumstances. The unit and the electrodes must be positioned so that

•

there is no danger of personal injury. Therefore, you must read and observe the safety instructions and the list of contraindications before putting the unit into operation.

The Electrode-Skin Distance (ESD) must be small for

•

surface warming and large for depth warming. A larger Electrode-Skin Distance (ESD) is necessary for patients with a thick layer of subcutaneous fat in order to achieve the necessary warming of deep-lying tissue.

which is the plasticizer for most PVC medical devices. Everyone is exposed to small levels of DEHP in everyday life. However, some individuals can be exposed to high levels of DEHP through certain medical procedures. DEHP can leach out of plastic medical devices into solutions that come into contact with the plastic. The amount of DEHP that will leach out depends on the temperature, the lipid content of the liquid, and the duration of contact with the plastic. As a preventative measure, use PVC devices that do not contain DEHP, or devices made of other materials such as ethylene (EVA), silicone, polyethylene, or polyurethane for all clinical procedures. Avoid using DEHP-leaching PVC when performing all clinical procedures on male neonates, pregnant women who are carrying male fetuses, or peripubertal males.

This chemical is considered an Unclassifiable Carcinogen and a suspected Endocrine disruptor which may interfere with or block hormones. BPA is highly toxic if swallowed, absorbed through the skin, or inhaled.

SAFETY INSTRUCTIONS

PROTECTION OF THE UNIT

Improper installation, operation or maintenance of the shortwave diathermy unit may result in malfunctions of this unit or other devices.

Observe the following instructions in order to prevent malfunctions:

In order to prevent electromagnetic disturbances, place • the unit at least 12 meters (see the Caution on page 2 for more information) from any other devices. Also make sure that there is sufficient distance between the unit and Mains Power Supply or data cables in walls, ceilings and floors, since the electromagnetic radiation from the unit can pass these essentially without hindrance.

In selecting the location for the unit, make sure that the • patient has contact during the treatment to the nonearthed application element and, due to equalizing currents in case of differing potentials, that the patient is never in contact with metal elements (especially if they are earthed), such as heating radiators, metal beds or other earthed devices.

Before connecting the unit, make sure that:

the voltage rating on the safety label corresponds to the • available system voltage.

the frequency rating on the rating plate corresponds to the • system frequency.

an earthed socket outlet with earthing contact is available • for connecting the unit.

the routing of the power cable from the unit to the socket • outlet with earthing contact does not pose a danger for personnel or the patient.

the Mains Power Supply is designed for the comparatively • high (possibly additional) power input of the unit (~500 VA) and the line is sufficiently protected in accordance with regulations.

Shortwave Diathermy

Do not connect the unit to the Mains Power Supply until the following requirements have been met:

Before putting the unit into operation, check to make sure • that the electrode connection cable and the electrodes are undamaged and have been connected correctly to the unit.

Never operate the unit with open outputs, (i.e. without • electrodes).

Do not operate the unit for an extended period with no • load (without a patient), especially in coil (induction field) mode.

Pay attention to the routing of the electrode connection • cables. These must always be in the air and must never lie on surfaces.

Other than Chattanooga Group equipment, keep chip • cards, magnetic cards, audio and video cassettes, and other data media susceptible to interference away from the unit.

Clean and disinfect the unit only when the Mains Power • Supply is deactivated (power switch off, power plug disconnected).

Clean and disinfect the unit only by means of disinfection • by wiping. Disinfecting by spraying can damage the unit due to penetrating moisture.

Never clean the unit with abrasives, disinfectants, or • solvents that could scratch the housing or damage the unit.

Never perform unauthorized service work. All service work • must be performed only by service technicians who have been authorized by the manufacturer.

Make certain that the unit is electrically earthed by connecting only to a earthed electrical service receptacle, conforming to the applicable national and local electrical codes.

THEORY OF OPERATION

Shortwave Diathermy

OVERVIEW

Shortwave diathermy is the application of electromagnetic energy to the body at shortwave frequencies. At these frequencies, the electromagnetic energy is converted to thermal energy by the induction of circulating currents in the tissue and dielectric absorption in insulating tissue. Shortwave diathermy units may produce varying output power levels providing significant heat to the area of the body being treated. To avoid equipment such as shortwave diathermy units interfering with radio communications, certain frequency ranges are designated by international agreement as ISM (Industrial, Scientific, and Medical) bands.

Shortwave diathermy equipment normally uses the band centered on 27.12 MHz. This corresponds to a wavelength, in a vacuum, of approximately 11 meters.

Shortwave diathermy is normally applied at a level which produces detectable heating and the benefits are those associated with the heating effect (encouragement of healing, pain relief, reduction of muscle spasm, increase in mobility, etc.).

The difference between shortwave diathermy and other methods of heating is that it provides “deep heat.” Other heating techniques such as infrared therapy, hot packs, etc., provide the heat externally whereas shortwave diathermy generates heat within the tissue.

Pulsed Shortwave Diathermy - Introduction

Pulsed shortwave diathermy equipment delivers the energy in pulses or bursts of shortwave energy. The pulses are typically 20 to 400 sec in duration (pulse width) and are repeated with a frequency of 10 to 800 Hz (pulse frequency). As with other modalities such as ultrasound, it is found that delivering the energy in pulses is often therapeutically more beneficial than providing the same amount of energy in continuous waveform. Pulsed shortwave diathermy appears to be effective for many conditions especially in the early stages of recovery.

Because the output is pulsed, the average output power levels can be very low (less than 1 W) and still produce the effective treatment. The unit in pulsed mode provides a peak power of 200 W and average powers from a few mW to 64 W.

As the power levels are lower than with conventional shortwave diathermy equipment, some of the potential dangers associated with the modality no longer apply. The unit is of modular design. All individual parts can be installed and removed easily. Electrical and electronic modules are connected via plug-in connectors, eliminating the requirement for any solder.

The unit's electronics are located inside the chassis and underneath the LCD and on the PCB's for the Power Supply, amplifier, and RF Generator Assembly. The Power Supply, amplifier, and the RF Generator Assembly are located within the chassis behind the Rear Extrusion. The PCB's and other electrical modules are connected to each other by plug-in connectors and ribbon cables.

The unit and the accompanying components and individual elements fulfill, as a unit, the currently valid safety standards and comply with the stipulations of IEC 60601-1 and the medical products regulations.

The unit and its external components (accessory elements) are safe if used properly and in compliance with the explanations and instructions provided in this documentation. Nevertheless, the unit or its external components can pose dangers. Therefore, we strongly recommend that anyone operating the shortwave diathermy unit become aware of the potential dangers of the unit and its external components before beginning work.

Please read and observe all safety instructions in this service manual.

EFFECTIVE POWER  PULSED MODE

The effective power is the energy output which has a thermal or heating effect in the tissue of the patient. In continuous mode, therefore, the output power is identical with the effective power. Hence, the effective power shows the equivalent heating effect of the output in continuous mode.

The pulsed mode, in contrast, is known as athermal therapy, since the effective power is so minimal that the perceptible heating effect is not the point of the therapy. The main effect is pulses with high maximum energy outputs, and therefore, the deep-reaching effects are the widening of the vessels for improved blood circulation, trophic improvement, and prevention of inflammation. To achieve these effects, the effective power should not exceed 25W, otherwise the opposite can occur (i.e. a narrowing of the vessels).

The effective depth will depend on the maximum output. This means that therapy can reach considerable depths of tissue, even if the thermal load involved is considerably lower.

By changing the pulse frequency, the effective power can be adjusted to the desired level, even with high maximum pulse outputs (i.e. greater deep-reaching effects). The set effective power is shown on the graphic display. This makes the relationship between pulse frequency and thermal/heating effect (effective power) immediately clear.

The higher the pulse frequency, the greater the thermal effect.

THEORY OF OPERATION DIAGRAM CONTINUED

First block: IEC Connector

Power is supplied through the appropriate line cord via the IEC connector.

Second Block: 24 V Power Supply

System power is provided by the 24 V DC/350 W Power Supply.

Third Block: Variable Power Supply/Buck Power Supply

This block in the power flow serves the following four basic functions:

Generates 12 V from the 24 V to power some circuits in the rest of the system. 1.

Distributes 24 V to rest of system.2.

Generates variable power from 0 to 128 V DC that is used to power the final amplifier in the RF Generator Assembly.3.

Provides an additional relay (operated by the patient switch and watchdog) to shut down power to the RF Generator Assembly.4.

Fourth Block: Micro Controller and RF Generator Assembly

This block is the RF Generator Assembly. It consists of two parts: a Micro Controller and an RF Generator Assembly.

Micro Controller

The Micro Controller monitors and controls the RF Generator Assembly. It also communicates with the Control PCB (7th block) that serves as the user interface (Touch Screen LCD). Communication between the Micro Controller and the Control PCB is via RS 485. Power for the 7th block also comes from 4th block.

Auxiliary Functions of Micro Controller

The Micro Controller also functions to:

measure the temp of the heat sink• control the fan and blower speed• monitor the state of Patient Interrupt Switch• control the relays on the tuner board• communicates with the Directional Coupler PCB (5th block).•

RF Generator Assembly

The RF Generator Assembly produces the RF power used for treating the patient. There is a 27.12 MHz clock on the PC board. The output of the clock is gated by control line from the Micro Controller to control the duty cycle of the RF Generator Assembly. Power output of the RF Generator Assembly is controlled by varying the voltage of the Variable Power Supply (2nd block). The output voltage of the Variable Power Supply is controlled by the Micro Controller via analog voltage from a D/A converter.

Fifth Block: Directional Coupler PCB

The RF output of the RF Generator Assembly is transferred through the Directional Coupler PCB. The Directional Coupler PCB measures the forward and reverse power and provides feedback to the Micro Controller on the RF Generator Assembly (4th block). It also has a memory device that stores calibration information. DC power (+5 V) for this block is provided by the 4th block.

Sixth Block: Tuner Box

The Tuner matches the output of the unit to the patient load. It does this by using relays to switch coils and capacitors. Efficacy of tuning process is measured by the Directional Coupler PCB (5th block). DC power (+24 V) for this block is provided by the 4th block.

Seventh Block: Control PCB

The 7th block is also known as the Control PCB, GUI (Graphical User Interface) and the Touch Screen LCD. This block accepts commands from the user. and provides feedback to the user during operation. DC power (+24 V) for this block is provided by the 4th block.

To verify that shortwave diathermy energy is actually being transmitted, this small, fluorescent tube illuminates when it’s held between the capacitive or flexible rubber electrodes, or near the monode and diplode (assuming a therapy session is in progress).

NOTE: The Indicator Discharge Tube will not illuminate if

the output power is at a low setting.

Equipment Required

Load: Plastic container with saline solution• Indicator Discharge Tube•

Using the Indicator Discharge Tube

Place a plastic 1. container filled with a saline solution between the two Capacitive Electrodes. If you are using the monode, place it against one side.

NOTE: The plastic container should be elevated off the floor

at least 18 in (45.7 cm), via a non-conductive rest, to maintain separation between the plastic container and the potentially steel-reinforced concrete floor.

Unit is not Powering Up

If unit does not power up, do the following:

Check the power cord to make sure that it is fully plugged 1. into IEC connector on the side of the unit.

Check the 24 V Power Supply.2.

If the 24 volt Power Supply is providing 24 volts to the unit 3. and the system still does not power up, replace the Control PCB.
