1 THEORY OF OPERATION

1.1 OVERVIEW

The Senior Solutions Therapy System are comprised of several PC board assemblies housed within a common enclosure. These assemblies each support a distinct function in the product. The basic elements are User Interface, Control Board, Stim Board, Ultrasound Board, Ultrasound Applicator, and Power Supply Circuits.

When a Module (Channel 3/4 Electrotherapy, NiMH Battery, or sEMG) is installed, the Control Board software automatically recognizes that a Module has been installed and prompts the installer to perform certain tasks, for verification of Module installed and to make the respective Module fully functional. No additional software installation is required as the Therapy System contains all necessary software to accommodate any Module installation.

1.2 POWER SUPPLY CIRCUITS

A universal input 100 Watt power supply provides the Control Board and Stim Board of the system with 24 volts DC. The supply is connected to the mains at all times when the cord is attached. The 24 VDC supply is regulated locally at each PC board as required. On Combination Systems, a separate universal 75 Watt Power Supply provides 24 volts DC to the Ultrasound PC Board. The 24 volt DC power is regulated at the board, as required.

1.3 CONTROL BOARD

The Control Board serves just as its name implies. It controls the operation of the stim board, ultrasound board, user interface, optional modules, and accessories. The control board communicates to the stim boards and ultrasound board through a proprietary bus. The control board drives the display. The control board reads the menu Buttons. The control board reads and manages the Multimedia (MMC) Card, Patient Data Card, and sEMG Data Card. Sound output is generated by the control board and routed to an internal speaker. The control board reads the Optional Patient Interrupt Switch and the Operator Remote Control (used to administer Manual Stimulation Therapy).

1.4 STIM BOARD

The Stim Board creates all muscle stimulation output. Communications to the Stim Board is via a proprietary bus. A processor on the Stim Board acts on messages passed to it by the Control Board to set up waveforms and adjust output amplitude. Information can likewise be passed from the Stim Board back to the Control Board for monitoring Current, Microcurrent Probe Contact Quality indication, etc. If the Stim Board does not respond as expected to a command from the Control Board, output is STOPped and an Error Message is generated.

1.5 ULTRASOUND BOARD AND APPLICATOR COMBINATION SYSTEMS ONLY

The Ultrasound Board generates the 1 or 3.3 MHz output to drive the Sound Head of the Applicator. The Ultrasound Board is accessed through the proprietary bus by the Control Board. It can provide current and voltage information about the ultrasound output of the board. The calibration data for the Sound Head is passed through the Ultrasound Board from the Applicator to the Control Board. By storing the calibration data in the Applicator, there is no calibration necessary for the Ultrasound Board and any calibrated Chattanooga Group Senior Solutions Therapy System Applicator can be connected and operated to provide accurate coupling and output.

1.6 USER INTERFACE AND ACCESSORIES

The LCD display panel provides the operator visible feedback in the way of menu choices. Pressing the menu Buttons makes selections from the menus. The control board interprets these user inputs and responds accordingly. Audible feedback is given as well to indicate key presses and end of treatment.

The Control Board accesses the Patient Data Card, sEMG Data Card and MMC Card via an on board Reader/ Writer Interface. The voltage necessary to operate the reader is provided by the 100 Watt Power Supply and is regulated by the Control Board.

A. Channel 3/4 Electrotherapy Module

The Channel 3/4 Electrotherapy Module creates all muscle stimulation output for Channels 3 and 4. The Channel 3/4 Electrotherapy Module is interfaced with the System via a ribbon cable which supplies power and facilitates communication between the Stim Board and Control Board of the system. All waveforms available to channels 1 and 2 are available to channels 3 and 4 via the system software. No additional software is required for full functionality of the module.

1.6 USER INTERFACE AND ACCESSORIES (CONTINUED)

B. NiMH Battery Module The NiMH Battery Module incorporates two Nickel Metal Hydride (NiMH) Battery packs and

a PC Board. The PC Board monitors the Charge Level of the Batteries. The Batteries supply 24 VDC to the system which is then distributed to the respective pcb’s through the system power supply. The Battery Module is interfaced with the system via a ribbon cable that facilitates communication with the Control Board and delivery of power to a Two Channel Electrotherapy or Combination Therapy System. When the Therapy System is connected to a Mains Power Supply via the Power Cord, the NiMH Battery Module will charge. Once the Module is fully charged the software will STOP the charging process eliminating the possibility of overcharging. Battery power is used only when the Therapy System is not connected to a Mains Power Supply.

C. sEMG Module The Surface Electromyography (sEMG) Module utilizes a PC board to communicate to the Stim and

Control Boards via direct PC Board Contacts. The sEMG module reads and transmits muscle activity through lead wires and electrodes. The sEMG Module communicates muscle activity data to the Control Board which can store the data on an sEMG Data Card via the onboard Card Reader/Writer for viewing on a PC in graph form via the optional Chattanooga Group Patient Data Management System (PDMS) Software and Card Reader.

D. Operator Remote Control The Operator Remote Control is just as its name indicates and incorporates a PC Board. The Channel 1/2

Operator Remote Control is interfaced with the Therapy System through its unique connector on the front of the Therapy System and the Channel 3/4 Electrotherapy Module. The Operator Remote Control communicates with the Stim Board(s) to the Control Board for the administration of Manual Stim Therapy only.

E. Therapy System Cart The Therapy System Cart is designed for use with the Chattanooga Group Therapy System only. The

cart alone provides mobility to the Therapy System and storage of necessary accessories and supplies used in conjunction with the Therapy System.

contact with each other could result in improper stimulation or skin burns.

•

Long term effects of chronic electrical stimulation are unknown. Stimulation should not be applied over the anterior neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing.

Stimulation should not be applied transthoracically in that

•

the introduction of electrical current into the heart may cause cardiac arrhythmia.

Stimulation should not be applied over swollen, infected,

•

and inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.

Stimulation should not be applied over, or in proximity to,

•

cancerous lesions. Output current density is related to electrode size. Improper

•

application may result in patient injury. If any question arises as to the proper electrode size, consult a licensed practitioner prior to therapy session.

The Senior Solutions optional modules and associated accessories

•

are designed for use only with the Chattanooga Group Electrotherapy and Combination unit.

Use only accessories that are specially designed for this device.

•

Do not use accessories manufactured by other companies on this device. Chattanooga Group is not responsible for any consequence resulting from using products manufactured by other companies. The use of other accessories or cables may result in increased emissions or decreased immunity of this device and can degrade minimum safety.

DO NOT connect the unit to an electrical supply

• without first verifying that the power supply is the correct voltage. Incorrect voltage may cause unit damage, malfunction, electrical shock, fire, or personal injury. Your unit was constructed to operate only on the electrical voltage specified on the Voltage Rating and Serial Number Plate. Contact your dealer if the unit is not properly rated.

Power Supplies retain High Voltage!

• the event of battery cell rupture or leakage, handle battery module wearing neoprene or natural rubber gloves. Contents of a ruptured or leaking battery can cause respiratory irritation. Hypersensitivity to nickel can cause allergic pulmonary asthma. Contents of cell coming in contact with skin can cause skin irritation and chemical burns.

Stimulus delivered by the TENS waveforms of this

•

device, in certain configurations, will deliver a charge of 25 microcoulombs (μC) or greater per pulse and may be sufficient to cause electrocution. Electrical current of this magnitude must not flow through the thorax because it may cause a cardiac arrhythmia.

Patients with an implanted neurostimulation device

•

must not be treated with or be in close proximity to any shortwave diathermy, microwave diathermy, or therapeutic ultrasound diathermy anywhere on their body. Energy from diathermy (shortwave, microwave, ultrasound) can be transferred through the implanted neurostimulation system, can cause tissue damage, and can result in severe injury or death. Injury, damage or death can occur during diathermy therapy even if the implanted neurostimulation system is turned “off.”

Handle, clean and dispose of components and

•

accessories that have come in contact with bodily fluids according to National, Local and Facility rules, regulations and procedures.

Equipment not suitable for use in the presence of

The specifications found in this section provide the necessary waveform specifications to aid in troubleshooting. A waveform graphic from an oscilloscope is also provided for clarification.

Refer to this section when performing troubleshooting, replacement, and repair of the Therapy System, Modules, and Accessories.

A. IFC (Interferential) Traditional (4 Pole) Figure 4.2

Interferential Current is a medium frequency waveform. Current is distributed through two channels (four electrodes). The currents cross each other in the body at the area requiring treatment. The two currents interfere with each other at this crossing point, resulting in a modulation of the intensity (the current intensity increases and decreases at a regular frequency).

5.2 THERAPY SYSTEM TESTING

A. General

The following information is intended to aid

in troubleshooting the major components of the Senior Solutions Therapy System to “board level” only. These tests are FACTORY standard testing procedures and methods used at the factory before shipment of any Senior Solutions Therapy System.

Due to the complex nature of the technology

utilized by Chattanooga Group, the recommended troubleshooting techniques are to determine “Bad Board” and board replacement only. No board componentlevel troubleshooting is recommended nor will information or parts be supplied by Chattanooga Group. Any board componentlevel troubleshooting performed will be at sole risk and liability of the Service Technician performing such troubleshooting techniques.

Once a particular PC Board has been

determined as bad, refer to the appropriate Removal and Replacement Section of this Manual for proper replacement.

B. Special Tools, Fixtures, & Materials Required

Certain tests require the use of special

tools and fixtures. These will be listed at the particular test where they are required. Testing with any other special tool or fixture other than those stated could give erroneous readings or test results. Always perform the tests exactly as stated to ensure accurate results.

Any special tools or fixtures required can

be obtained through Chattanooga Group Service Department.

Scope and other standard test equipment

settings will be listed for each test performed to aid in performing the test to FACTORY standards and ensure proper readings.

The troubleshooting and repair of the Senior

Solutions Therapy System, Modules, and Accessories should be performed only by authorized technicians trained and certified by Chattanooga Group.

C. Equipment Required

Oscilloscope and Probes.

ESTI-2 Load Test Fixture.

Digital Multimeter.

Microcurrent Probe (Accessory).

Patient Interrupt Switch (Optional Accessory).

Operator Remote Control (Optional

Accessory).

Senior Solutions™ Therapy System

Senior Solutions Therapy System Ultrasound Applicators (Accessories).

Dielectric Withstand (Hi-Pot) and ground resistance tester.

NOTE:

Adjust Dielectric Withstand tester to indicate fault with 120 k Ohm Load across the output when at specified test voltage.

Milliohm Meter.

Ohmic Instruments UPM DT 10 or DT 100 Ultrasound Power Meter.

Audio Signal Generator, B-K Precision, Model 3001.

Dissolved Oxygen Test Kit. Used to test oxygen level of degassed water.

Degassed Water (<5 ppm) for Ultrasound Power Meter.

D. Recipe(s) for Degassed Water

Boil distilled water for 30 minutes. Place water in a non-porous container and immediately cover with cellophane. Allow to cool to room temperature of approximately 70 °F (21 °C). May be refrigerated to aid cooling time.

Bring distilled water to a boil. Place the container under vacuum for 5 to 10 minutes.

NOTE:

Two liter soft drink bottles are ideal storage and transport containers for degassed water as they are designed to keep oxygen out. Do not allow aeration of degassed water during transport or filling of the power meter.

Do not use tap water or distilled water in the Ultrasound Power Meter. Use only degassed water in order to obtain correct test results. The chart below illustrates the oxygen content of degassed, tap and distilled water.

WATER TYPE ppm of Oxygen

Degassed per recipe 1 or 2 Less than 5 ppm

Tap Water Up to 35 ppm

Distilled Water Up to 20 ppm

E. Full Functional Tests

Perform the tests found in this section to verify full functionality of new Therapy Systems and related Modules and accessories.
