Buying a portable ultrasound machine: 10 things you need to know to get the right equipment
Introduction
Ultrasound has become an essential tool in modern medical practice. With the advent of portable or ultraportable ultrasound scanners, healthcare professionals can now benefit from this technology anytime, anywhere. However, choosing the right portable ultrasound system can be complex, given the variety of models and features available. This article walks you through the 10 key elements to consider to make an informed choice tailored to your needs, while specifying what is essential to practice clinical ultrasound.
1. Define your needs
Before you embark on the purchase of a portable ultrasound system, it is essential to define your needs in terms of clinical applications. What are the main pathologies you encounter? What types of ultrasound examinations do you want to perform? In the context of a general practice of clinical ultrasound, the detection of effusions, the diagnosis of pneumopathies, the detection of masses or vascular observation represent the vast majority of use cases. Probes with frequencies ranging from 3 MHz to 8 MHz can observe the majority of superficial (more than 1 cm deep) and deep (up to 25 cm) organs. For musculoskeletal, gynaecological or dermatological uses, the choice will fall on probes dedicated to these uses but which do not cover the other perimeters.
2. Opt for a versatile and affordable device
Contrary to popular belief, a high-performance portable ultrasound system does not have to be synonymous with high cost. On the other hand, an expensive device does not necessarily mean a better diagnosis. Many affordable models offer basic functionality suitable for a wide range of clinical situations. Don't hesitate to compare the prices and technical specifications of different devices to find the one that best suits your needs and budget. Particular attention should be paid to customer service and the entity that distributes the product. Indeed, in the context of maintenance, it is preferable to have a well-referenced player in France.
3. Prioritize ease of use
A portable ultrasound system should be easy to use to ensure that it is quick to use and is efficient. Opt for a camera with an intuitive interface and easy-to-adjust settings such as frequency, gain, and zoom on the image. The presence of a clear and detailed instruction manual is also an asset to facilitate your learning. To be effective, you must have less than thirty seconds between the time you turn on the device and the time you visualize your patient's anatomical structures.
4. Check Image Quality
Image quality is a determining factor when choosing a portable ultrasound system. Make sure the device has sufficient resolution to properly visualize anatomical structures and make accurate diagnoses. Sufficient image quality should allow you to assess heart function, bladder volume, or the size of a lump. Feel free to consult the opinions of other healthcare professionals or request a demo to assess the image quality of the device.
5. Choose the right probe
The probe is the key component of the portable ultrasound system. It should be tailored to your needs in terms of frequency, shape, and size. Very high frequency linear probes exist and are generally used for superficial examinations (tendons and muscles), while sectoral or convex probes are more suitable for abdominal and obstetric examinations. Some probes such as echOpen have integrated three frequencies into a single probe nose, allowing the probe to be traversed from the surface to the deep organs without the need to flip the probe.
6. Don't overestimate the added value of Doppler
Although Doppler may be useful in some specific clinical situations (e.g., assessment of vascularity), it is not essential for the majority of common ultrasound examinations. A portable ultrasound system without Doppler can therefore meet most of your needs, while being more affordable and easier to use. In the case of suspected phlebitis, 4-point ultrasound can thus be performed without Doppler.
7. Consider Robustness
One of the main advantages of a portable ultrasound machine is how easy it is to transport. Be sure to choose a compact, lightweight and above all robust device that can accompany you on your daily commute without taking up too much space. Ultra-miniaturization is interesting; On the other hand, it often comes at the expense of other factors, such as the heating of the probe, which can cause a sudden shutdown, or the deterioration of image quality.
8. Consider battery life
A portable ultrasound machine should have enough battery life to allow you to perform several consecutive exams without having to recharge the battery. Find out about the average lifespan of the device and look for models with long-lasting batteries. A good indicator of performance will be the ability of the battery to last a whole day of consultations without needing to be recharged. In the case of a general practitioner, your device should be able to perform more than ten ultrasounds in the same day.
9. Check compatibility with your smartphone
To make it easier to manage and share data, it's important to choose a portable ultrasound machine that's compatible with your smartphone. All manufacturers are required to publish a list of phones with which they are compatible. echOpen has verified its compatibility with more than 300 Android and Apple models.
10. Ensure after-sales service and warranty
Finally, don't forget to inquire about the warranty and after-sales service conditions offered by the manufacturer or distributor of the portable ultrasound system. Good follow-up and effective technical support are essential to ensure the sustainability of your investment and guarantee your long-term satisfaction. When making a purchase with echOpen, you get a one-year warranty, with replacement to new.
Conclusion
Buying a portable ultrasound system should be directly related to your most frequent use cases. By taking into account these ten key elements, you will be able to make an informed choice adapted to your needs, the three most important elements in your buying journey are to ensure that the probe meets the essential needs of your uses, that the image quality is sufficient for diagnostic guidance and that the price is affordable for your practice.
