  • Page 19: Ultrasound And Its Application

    Ultrasound and Its Applications Human perception of sound waves is limited to frequencies of fewer than 20,000 vibrations per second. Higher frequency vibrations — between 0.7 and 3.3 MHz — are used for ultrasound therapy. (Most ultrasound equipment produces an output of between 1 and 3.3 MHz.) An ultrasound unit produces electrical oscillations at a specified frequency that cause the transducer in the ultrasound applicator...

    another and of changing the tensile strength of tendons, thereby increasing their extensibility. The physiological benefits from ultrasound therapy are numerous. Ultrasound therapy affects the peripheral nerves by chemically changing the conduction velocity (this has been shown clinically in situ). Ultrasound alters the diffusion of Na+ and K+ (sodium and potassium) across red blood cell membranes.

    Transformer Unit power jack 3. Allow sufficient time for the UW 5 to fully adjust to room temperature. If the unit is not at room temperature, the transducer will be slowly warming or cooling and will cause the readings to shift.
  • Page 37 5. Open the bottle of degassed water. When the vacuum seal is broken you should be able to hear it. If you do not hear or feel the vacuum, discard the water. 6. Use a Dissolved Oxygen Test kit to ensure that the oxygen content of the water is less than 2 ppm.

    45 minutes to 1 hour. 2. Turn on the UW 5 using the ON switch on the front panel. Ensure that the unit is in the Watts mode (displayed units will read 0).
  • Page 39 Remove the tube from its clip and raise the tube end above the level of water in the tank before removing the drain cap, to avoid getting wet. 8. Dispose of any water left in the opened bottle of degassed and distilled water. The water will absorb oxygen over time, rendering it ineffective as a coupling medium.
  • Page 40: Using The Universal Transducer Clamp Assembly And Centering Rings

    Using the Universal Transducer Clamp Assembly and Centering Rings The universal transducer clamp assembly frees the operator from holding the transducer treatment (radiating) head in the coupling water and prevents transducer movement, ensuring more accurate and stable readings. The centering rings help to properly center and aim the transducer head in the tank.

    4. Record these values under Ultrasound Setting on the label. 5. Measure the output on the UW 5. 6. Record the UW 5 reading under Actual Output in Watts on the performance label. Testing Using Exact Meter Settings (Method II) When this method is used, an exact meter setting is obtained for each power desired.

    Do not spill water on the front or rear panel. Do not apply more than 30 W of input power to the UW 5. Do not operate the UW 5 for more than 1 hour during testing. Change the water between hour-long tests.
  • Page 47: Maintenance

    Maintenance Maintenance of the UW 5 Wattmeter is straightforward, requiring little more than keeping it clean. It is important to keep dust and dirt out of the transducer tank. Rinsing the tank with very clean water before use, along with proper storage in the carrying case, is all that is required.
