Improved ergonomics and better reproducible cardiac ultrasound images

Book a demo


    ProbeFix is a non-invasive ultrasound accessory tool which provides lengthy and stable fixation of an ultrasound probe to the body. The device facilitates hands-off workflow, continuous measurement and reproducibility of the ultrasound image. As a result, it significantly optimizes examination quality. Stress echocardiography procedures and cardiac output monitoring at the intensive care department directly benefit from this ultrasound probe fixator, the ProbeFix.


    Monitor the heart for longer periods of time, thanks to a stable fixation to the body.


    Enable a highly reproducible image by the perfect positioning of the probe.


    Execute your examination fully focused to deliver the best possible care.

    Improved ergonomics

    Reduce the time you manually hold the probe and sit in an awkward position.

    The Smart Ultrasound Solution

    Hygienic Straps

    Fully disposable high-quality straps ensure optimal hygiene.

    Modular Probe Adapter

    Different Probe Adapters guarantee a perfect fit of each ultrasound probe.

    Silicon Feet

    Silicon feet combine perfect grip on the body with great comfort for patients.

    Sphere Mechanism

    Carefully designed mechanism facilitates effortless movement into the right position.

    Perfect Stable Position

    A patented mechanism ensures a perfect stable position of the probe, for as long as required.

    Easy To Clean

    Take apart easily to clean all different components.



    Stress echo

    During stress echo exercise on bicycle or treadmill ProbeFix provides continuous monitoring possibilities and better reproducibility of the images.

    Diagnostic ultrasound procedures

    Monitor the heart for longer periods of time, because of a stable fix to the body.

    Pacemaker optimisation

    Enable a highly reproducible image by the perfect stable position of the probe.

    Cardiac output monitoring

    Cardiac output monitoring can be done in a non invasive and high quality visual way.

    Cardiac Output Monitoring In Intensive Care

    ProbeFix enables lengthy ultrasound imaging at the Intensive Care department, as demonstrated by Dr. Michiel Blans and Dr. Frank Bosch of the Rijnstate Hospital.

    We use the Probefix in order to get reliable results

    Others about the ProbeFix

    I just love innovations like this. ProbeFix can change the way we perform ultrasound in the future. It has great potential in combination with 3D probes, especially in stress echocardiography. With ProbeFix, echo is less strenuous and will prevent arm and shoulder injuries.

    Prof. Thomas Binder, MD PhD

    CEO 123sonography GmbH

    I do not have to push anymore. With this patient I had had too much trouble with my shoulder without ProbeFix, now it’s acceptable

    Senior sonographer

    Deventer Hospital

    A facility will incur a cost averaging more than $500k per annum, per sonographer for injuries sustained in their work, a very high percentage of sonographers carry between 1 and 4 injuries at any one time which eventually take their toll!

    Bernadette Mason

    Consultant and advisor Sono's Safety in the Workplace

    Using the ProbeFix has been a true revelation. It really is a simple and practical solution to an every-day problem, and even in this test phase it shows exceptional potential. Not only does it ensure a more stable echo image, but eventually it will also provide better reproducible images throughout the cardiac stress test. So, it is likely to save us time and costs, while also decreasing the inter-observer variability in our echocardiography lab. And my back, neck and shoulders will be less tired and stressed.

    Dr Ciprian Albu

    Cardiologist St Dimpna, Geel, Belgium

    If we make an echo of the heart, we need to manually hold the transducer for long periods of time against the chest of the patient. A difficult position that can easily lead to RSI complaints. With the ProbeFix this can be solved. Our staff will now be relieved and will be even more efficient by being able to work hands-free.

    Maarten Jan Cramer

    Cardiologist UMC Utrecht

    Sometimes innovations are so simple that it is surprising that they were not there before. ProbeFix is an example that relieves the sonographer and improves the images that are made. Moreover, the enthusiasm of the team contributes to their success.

    Lucien Engelen

    Director REshape Center at the University of Nijmegen

    The ProbeFix by Usono gives more control to clinicians and will broaden the field of ultrasound applications.
