One: equipment use
According to the standardized requirement of the purchasing equipment, we should carry out the bone mineral density monitoring of multiple age, osteomalacia (rickets), auxiliary diagnosis of osteoporosis, and evaluate the relative risk of fracture among the elderly.
Two: technical parameters
1. all dry along the bone shaft measurement, inspection process simple, intelligent integration, no need to take off shoes, cross infection prevention;
2. four wafers, dual emission and dual receiving modes were used to quantitatively measure bone transmitted sound velocity (SOS) without radiation;
3. radius + tibia, double site measurement; more comprehensive and systematic analysis of bone mineral density;
4. using USB signal digital acquisition communication technology to collect stability;
5. one of the original brand workstations, free upgrades (with color LCD display, color inkjet printer);
6. portable broadband ultrasonic focusing probe, high sensitivity chip materials and six concentric copper shielding plug; the automatic elimination of soft tissue interference, a single examination gets more than 40000 sets of data, ensure the accuracy and repeatability of data.
7. The probe navigation technology: real-time display of contact state, probe and probe skin and skeletal parallel state, to facilitate the rapid correction detection technique to improve the detection efficiency.
8. The probe center frequency 0.5MHz, high sensitivity, infant fat people can use;
9. speed SOS measurement accuracy: the accuracy is less than 0.15%;
10. speed SOS measurement error range: the error is less than 0.5%;
11. speed SOS measurement repeatability: coefficient of variation is less than 0.3% CV;
12. speed of sound SOS measurement range: 2300-4800m/s;
13. A large population of infants (0-3 years of age), children (0-20 years of age), pregnant women (20-50 years old), adults (20-100 years old), automatic professional software analysis and reporting;
14. neonatal and infant (birth 30 days) professional measurement advantage model, especially for infants and young children special scanning check;
15. A variety of measurement time mode is optional: single point detection time of 2 seconds, fast, medium speed, slow, a variety of measuring mode optional.
16. the measurement process is automatic, one-time measurement, the completion of the results, without foot switches or buttons triggered several times;
17. calculation parameters: sound velocity (SOS), T value, Z value,% percent, expected age of onset of osteoporosis (EOA), relative fracture risk (RRF), etc.;
18. The complete range of calculating parameters: velocity (SOS), T value, Z value, expected% percentage, osteoporosis, age (EOA), the relative risk of fracture (RRF), children's bone age prediction, prediction of height etc.;
19. SQV - film calibration test to ensure the accuracy and repeatability of the factory;
20. The software with independent copyright and source code (the need for software copyright certificate), case database management system, automatic recording, query, classification, backup, printing, fast and convenient;
21. equipment should have proprietary technology patent, patent certificate is required.
22. factories need ISO13485 certification and provide certificates.
22. complete Internet function and communication protocol to facilitate expert remote consultation and networking, as well as network upgrade;
23. comply with GB9706.1, GB9706.9, GB9706.15, YY0774-2010 and other national, industry standards and national safety standards;
25. using power supply: AC, 220V + 22V, 50Hz + 1Hz;
26. input power: 180VA;
27. operating environment: temperature: +5 to +40 degrees celsius;
Humidity: 30% to 85%;
