Rev.1.01 Chapter 4. Maintenance 4.1 Charging Probe 4.1.1 USB Charging When the battery is low, the probe needs to be charged. Remove the rubber cover from the tip of the probe and then plug one end of the USB cable into the USB charging port in the probe as shown in Figure 4-1. The battery level indicator blinks while charging. The battery is fully charged when both the battery level indicator and the wireless link indicator are not blinking.
Rev.1.01 4.2 Cleaning and Disinfecting Probes All probes must be cleaned and disinfected before and after each use. Use a soft cloth or appropriate cleaning sheet, lightly dampened with Isopropyl alcohol (or proper cleaner), to remove any foreign substances left on the probe, the edges, corners, and curved parts of the probes. Dry the probe with a clean, soft cloth. Alternatively, dampen a soft cloth in a glutaraldehyde-based hospital disinfectant solution such as Cidex.
Rev.1.01 Check whether other equipment Displayed on the screen with noise started which cause electromagnetic 3 and interference like snow interference. If so, shut down the device or get far from the device. The brightness of image is not 4 enough Adjust the brightness and gain Check whether the USB interface, 5 Charging is NOT work circuit and electrical outlet are damaged or not. 4.5 Disposal Warning Do not dispose of the product carelessly.
Rev.1.01 Service department. 8. Since the probe is vulnerable to external impact, collision or falling is prohibited. 9. If you want to pause during scanning, use the “Freeze” function. In freeze status, the device can be kept on standby for a long time. 10. Only use the appropriate ultrasound gels for medical standard. 11. The probe is waterproof but, do not immerse the probe in conductive liquid to minimize corruption. 12.
Rev.1.01 Chapter 5. Biopsy A biopsy is an examination method that surgically extracts tissue from the patient for examination. The probe and the biopsy components are used together when conducting a biopsy with the ultrasonographic image scanner. The ultrasound system shows the needle, which penetrates through the skin surface and veins, along with the examination location, minimizing the risk to the patient.
Rev.1.01 Warning - Only use needle approved for use in your country. - Verify the condition of the biopsy needle before use. Do not use a bent biopsy needle. - The needle and guide must be sterilized before use. - The needle may bend while penetrating tissue. Therefore, the actual location of the needle must be checked by monitoring the echo generated from the needle.
Rev.1.01 to the patient. ④ Scan the patient. Adjust the patient so that the location for examination fits into the needle guideline on the screen. ⑤ Insert the needle into the needle guide. Perform the puncture by sliding the needle through the groove in the guide until the needle intercepts the target. ⑥ To prevent the needle from shaking, press down on the top of the needle guide with your index finger during examinations. ⑦ When the examination site is reached, take the needle out of the needle guide.
Rev.1.01 must be checked by monitoring the echo from the needle. ① Attach the biopsy components. ② Set the system depth for the procedure to be performed and select the Biopsy menu. ③ Immerse the probe into the water bath and insert the needle into the needle guide. ④ Confirm that the needle image is on the needle guidelines. If it is, then the needle guide is properly aligned. ⑤ If the needle image displayed on the screen is outside of the needle guide lines, check the needle guide. 5.
Rev.1.01 Chapter 6. Safety To prevent damage of the equipment or injury to yourself or others, read the following safety instruction before using SONOFINDER. 6.1 Important Safety Considerations Read the following safety instruction before using SONOFINDER. Warnings: - Do not use for any purpose other than the intended use. Otherwise, the system may be damaged or serious injury may result. - This device is for diagnostic use only and is not intended for therapeutic use.
Rev.1.01 - Check the probe for cracks, broken parts, liquid leaks, sharp edges, etc. If there is any damage, stop using the probe immediately and contact Customer Service Department. Warnings: - This product is intended for use by, or by the order of, and under the supervision of, a licensed physician who is qualified for direct use of medical devices. - This system may only be maintained by persons approved or trained by Bionet.
Rev.1.01 Warnings: - Check the probe for cracks, broken parts, liquid leaks, sharp edges, etc. If there is any damage, stop using the probe immediately. Using damaged probes may result in electric shocks and other hazards to the patients and/or users. - After disinfecting the accessory, it is necessary to flush the chemicals out of the accessory. Residual chemicals or gases left behind can not only damage the accessory but can also be harmful to human health. 6.1.
Rev.1.01 6.2 Acoustic Power Principle Warnings: - Guidance for the use of diagnostic ultrasound is defined by the “As Low As Reasonably Achievable (ALARA)” principle. By keeping ultrasound exposure as low as possible while obtaining diagnostic images, users can minimize ultrasonic bioeffects. - The operator should notice the effect of the heat on the patient body when the exam is performed around the bones and the nearby soft tissues which can transform the ultrasound energy to heat energy.
Rev.1.01 involved, TI could be one of three types. The soft tissue thermal index (TIs) : the user about the potential for heating within soft homogeneous tissue. The bone thermal index (TIb) : the user about potential heating at or near the focus after the ultrasound beam has passed through soft tissue or fluid, such as the skeletal structure of a 2-3 month-old fetus.
Rev.1.01 attenuation coefficient, choosing conservative values of tissue characteristic. Therefore, displayed MI and TI values should be relative information for reference, they serve to indicate to the operator whether a particular setting of the system increases or decreases the possibility of Thermal or Mechanical effect, used to help the operator be careful to use ultrasonic diagnostic system and follow the ALARA principle, these values cannot be equal to actual values. 6.2.3.
Rev.1.01 - Direct Controls The direct control of the acoustic output of this system is adjusting voltage size. But its maximum acoustic output shouldn't be more than displayed acoustic output limit in any modes. - Indirect Controls The controls that indirectly affect output are many imaging parameters. These are operating modes, frequency, focal point number/position, image depth and pulse repetition frequency (PRF). The operating mode determines whether the ultrasound beam is scanning or nonscanning.
Rev.1.01 patient is created or the application mode is changed, the system will retrieve the default settings. You can also reset the parameters. 6.2.5 ALARA It is required to practice ALARA when using ultrasound energy. Practicing ALARA ensures that the total energy level is controlled below a low level at which bioeffects are not generated while diagnostic information is being accumulated. The total energy is controlled by output intensity and total radiation time.
