Ultrasound Preventative Maintenance

Preventative maintenance on therapeutic ultrasounds is necessary to ensure the proper function of your ultrasound for a couple of reasons. Having your ultrasound maintained at least on a yearly basis will ensure the units longevity for years to come and will ensure that the unit is safe to use on patients and complies with the manufacturer and industry standards.

It is important to keep your ultrasound maintained as it will make sure that the ultrasound is administering the correct output for the prescribed procedure. It is common for an ultrasound to be out of calibration i.e.: either too high or too low.  If the output is too low or non-existent there is a chance that you may be not helping the patient as the patient is not receiving the prescribed treatment.  If the output is too high one of two things may happen, there is a chance that you can permanently damage the ultrasound applicator to the point where it will need to be replaced or that you may even cause discomfort to the patient by the applicator heating up, in some rare cases it can burn patients.

During the maintenance of an ultrasound there are many things that can fail.  Just like any piece of medical equipment that is plugged into a wall an electrical safety check is performed.  The electrical safety check includes checking the ground wire resistance, leakage current, and the total current output of the device.  If any of these safety checks fail there is a potential for a patient to be harmed or the device to fail.  Other things that typically fail during the preventative maintenance process may be any physical damage to the device, usually this is damage to the applicator or the applicator’s cord. Different failures that may occur with an ultrasound include various error codes that can mean a multitude of things from any of the circuit boards and their components failing to the applicator overheating or disconnected.

    What does it mean if the sound head is not coupling and the indicator light is always in the yellow and is beeping?

      Hi Patricia,

      Typically it means that the unit is not coupling which could be due to a number of reasons. The first thing to check is to ensure that you are using enough ultrasound gel and it is not expired. If you are using the correct amount of ultrasound gel and it is not expired then the problem could be with the ultrasound applicator or the calibration on the unit. The next step would be to have us inspect the unit to see if it is either a problem with the ultrasound applicator or the calibration on the unit. Please let me know if you have any other questions or concerns or send us an e-mail to discuss your options.

      Best Regards,
