In today’s increasingly diverse healthcare landscape, bone density testing is no longer confined to a fixed examination room in the radiology department. Community screening, rural charity clinics, school health checks, bedside testing in hospital wards, mobile health screening units… an ever-growing range of scenarios calls for a portable bone density device that can be carried around and used to carry out tests anytime, anywhere.
The Pinyuan Medical BMD-A Series Ultrasound Bone Densitometer was designed precisely for these scenarios.
Weighing just 4.3 kg, the BMD-A3 is about the same size as a laptop; it operates entirely without ionising radiation, making it safe for pregnant women, infants, children and the elderly; and its fully dry technology ensures more convenient screening. These three key features define a truly ‘mobile bone density testing station’.
I. 4.3 kg: The weight of a laptop, the capabilities of a mobile screening station
Traditional bone density screening equipment is often bulky and difficult to transport, and once installed, it is hard to move. In contrast, the Pinyuan BMD-A3 portable ultrasound bone densitometer weighs just 4.3 kg, allowing a single person to carry and transport it with ease.
What does this weight signify?
It means the equipment can follow the doctor, rather than the patient having to follow the equipment.
- At Wuhan Central Hospital, once the BMD-A3 has been successfully set up, it can be easily moved between different settings such as outpatient clinics and wards, enabling the convenience of ‘bedside testing’ and significantly improving the efficiency of diagnosis and treatment.
- At Dongying People’s Hospital, the BMD-A3 can be flexibly deployed across outpatient clinics, wards and primary healthcare centres.
- At Hubei Provincial Maternal and Child Health Hospital, the device supports on-site bedside testing, reducing the burden of transport for groups such as children and pregnant women.
No fixed installation site is required, nor are any special modifications to departments needed. Whether for mobile screening in health check-up vehicles, outreach visits by community health service centres, or inspections at primary healthcare facilities, the BMD-A3 can be deployed flexibly. In the context of mobile healthcare, ‘portable’ is not merely a slogan, but a tangible improvement in clinical efficiency.
II. Radiation-Free: Ensuring Safe Testing for Pregnant Women, Infants and Children
Radiation safety is one of the most sensitive issues in the field of bone density testing.
The Pinyuan BMD-A series utilises pure ultrasound technology, ensuring no ionising radiation or harm throughout the entire process. This means:
- Pregnant women can be screened—safely monitoring changes in bone mass before, during and after pregnancy to prevent gestational osteoporosis and postpartum bone loss.
- Infants and young children can be screened—accurately assessing bone density and bone strength in children and adolescents aged 0–18, monitoring growth and development, and enabling the early detection of conditions such as rickets and insufficient bone mass.
- Elderly patients can undergo repeated testing—meeting the need for routine, multiple dynamic bone density monitoring to observe the effectiveness of clinical treatment.
Real-world Application:
At Zhengzhou Central Hospital, the BMD-A1 was installed precisely because it poses no radiation hazard and offers high reliability, making it particularly suitable for pregnant women, children and special groups requiring repeated testing. At Wuhan Dongxihu District People’s Hospital (Xiehe Dongxihu Hospital), the BMD-A1 testing process is completely non-invasive, painless and free from ionising radiation; the test can be completed in just one minute, opening up a safe pathway for initial bone density screening.
III. Fully Dry Method: Making Testing More Convenient and Hygienic
The Pinyuan BMD-A series utilises fully dry technology, making screening more convenient.
During the test, simply apply an appropriate amount of ultrasound coupling gel to the surface of the probe and gently press it against the distal third of the radius or the mid-shin. No special preparation is required; the procedure is straightforward and measurements are taken quickly.
More importantly, the BMD-A series utilises the distal third of the radius and the mid-shin as the measurement sites—areas that are easily accessible and straightforward to examine. Selecting the radius and tibia for examination eliminates the risk of cross-infection; in contrast, measuring the feet could lead to the transmission of fungal infections such as athlete’s foot.
The fully dry method combined with radial/tibial measurement ensures both hygiene and safety whilst enhancing patient acceptance.
IV. More Than Just Portability: Accurate, Efficient and Intelligent
Portability does not equate to inferior quality. The Pinyuan BMD-A series stands up to scrutiny in terms of both accuracy and intelligence.
- In terms of detection technology, the device utilises axial ultrasound transmission technology and a dual-transmitter, dual-receiver mode, combined with multi-directional autocorrelation technology and dedicated algorithms. As ultrasound waves pass through bone, their speed is directly correlated with the calcium content within the bone—higher calcium content results in faster propagation, whilst lower calcium content slows the propagation speed. Consequently, the device offers high measurement resolution, enabling the early detection of bone mineral deficiency and osteoporosis, whilst also providing insights into bone stress to predict fracture risk.
- In terms of data accuracy, the device is equipped with a database covering the entire age range from 0 to 100 years, tailored to the Chinese population, with separate databases for children and adults. During testing, it automatically matches the subject’s age to accurately output multiple indicators, including T-scores, Z-scores and SOS (sound velocity).
- In terms of ease of use, the device features probe navigation, with the system interface displaying the contact status between the probe and the skin in real time, allowing the operator to quickly adjust the probe’s position and pressure. Medical staff can operate the device independently after basic training. Test reports are generated automatically, comprising multi-dimensional indicators such as ultrasonic sound velocity, T-scores, Z-scores and bone indices.
- lIn terms of quality assurance, the BMD-A series has passed electromagnetic compatibility (EMC) testing, ensuring more stable and reliable product quality; it has also obtained EU CE certification. Pinyuan Medical has been certified under the ISO 9001 international quality management system and the Huaguang CMD certification. As a drafting organisation for the national industry standard for dual-energy X-ray bone densitometers, Pinyuan Medical holds multiple national patents.
V. One Series, Three Form Factors, Covering All Scenarios
The BMD-A series comprises more than just the portable BMD-A3 model. Pinyuan Medical has developed a product portfolio featuring three form factors—portable, trolley-mounted and dual-screen—to cater to different clinical scenarios:
- BMD-A3 Portable Model — Weighing just 4.3 kg, the entire unit can be easily carried by a single person, making it suitable for mobile testing scenarios such as on-site screening, community health checks and general health surveys.
