■ No rays, no trauma:

BMD-A series ultrasonic bone mineral density detector has obvious advantages over X-ray bone mineral density detector, especially without radiation, which can completely avoid the carcinogenic and teratogenic side effects of X-ray bone mineral density detector. Especially in fetuses, children and adolescents, due to active cell growth, DNA is highly vulnerable to radiation damage and cancer. The elderly also have an increased risk of cancer due to the reduced ability of damaged cells to repair. Therefore, the use of X-ray equipment in pregnant women, children, adolescents and the elderly should be avoided as much as possible. To this end, the Ministry of Health has made clear regulations. The ultrasonic bone density meter does not have any rays, and is suitable for bone density examination of children, pregnant women and the elderly, which is safe and reliable.

■ Database advantages:

BMD-A series ultrasonic bone mineral density detectors use a unique multi-database system:

①Children database (0-12 years old)
②Youth database (12-20 years old)
③Adult database (20-80 years old)
④elderly database (80-100 years old)

The four database systems make the users more segmented and the measurement results more accurate.

All four databases were derived from survey data from the World Health Organization (WHO) standardized database of Asian populations, including large integrated populations in China, Japan, and South Korea, and were optimized through combinational analysis and statistical processing.

■ Operating advantages:

BMD-A series of ultrasonic bone mineral density detectors are used to measure 1/3 of the distal radius and the tibial break, which are easy to reveal and easy to operate without disinfection. The measurement speed is fast, the scanning time of one measurement cycle is less than 10 seconds, the three measurement cycles are less than 25 seconds, the measurement speed is fast, convenient for doctors and patients, and can be used for large groups of medical examinations. The choice of radius and tibia examination will not have cross infection, such as the choice of foot measurement, it can cause beriberi, athlete's foot and other fungal diseases to infect each other.

■ Precision advantage:

The ultrasonic velocity axial propagation technology is very sensitive to the density change of the medium contained in the object. When the ultrasound passes through the bone, its velocity is directly related to the content (or density) of the main medium calcium in the bone. If the content is high, the sound velocity will propagate faster. If the content is low, the transmission speed is slowed down. When its content changes by 0.1%, there can be a change in the propagation speed. Therefore, the measurement resolution is high, early bone mineral deficiency and osteoporosis can be detected, and ultrasound can also reflect bone stress information, which can predict the risk of fracture.

■ Accuracy advantage:

The BMD-A series of ultrasonic bone mineral density detectors feature the only leading technology - visual positioning technology. BMD-A series ultrasonic bone mineral density detector adopts the double-sending and double-receiving technology, and obtains two equidistant sound velocity values at the same time to indicate the parallel state of the ultrasonic device and the measured bone. It can display the axial Angle, horizontal Angle and direction Angle between probe and bone plane in real time, and display the change of Angle value in real time. These real-time displays facilitate rapid correction of detection angles, improve detection speed and improve data accuracy. When measuring, it can also display the working state of the four crystals of the probe and the intensity of the ultrasonic received signal in real time. The visual positioning system ensures the repeatability and accuracy of the measurement. The probe access adopts high shielding multi-point access method to reduce signal interference and increase the continuity and accuracy of signal transmission. The three-cycle automatic average calculation method is more accurate than the single-cycle measurement. The application of various technologies makes the accuracy and repeatability of BMD-A7, the high-end model of BMD-A series ultrasonic bone mineral density detector, less than 0.1%.

■ Software advantages:

BMD-A series ultrasonic bone mineral density detector An instrument equipped with intelligent analysis system, economical and practical. It can measure 0-100 years old people (children age: 0-12 years old, teenagers age 12-20 years old, adults age 20-80 years old, elderly age 80-100 years old, as long as the input age can be automatically identified into the corresponding database).
