The European patent office has granted Oscare Medical a patent titled “Method and device for measuring density of a bone”, patent number 2252206. The patent concerns the osteoporosis detection method used by OsCare Sono®, which is based on measuring the propagation speed of sound along the surface (cortical) layer of a peripheral bone, travelling the same distance in opposite directions to eliminate adverse soft tissue effect. The term of patent protection is twenty years.
Oscare Medical already holds this patent in China and Japan.
The measurement method used by OsCare Sono® allows for an accurate and reliable measurement as the effect of the soft tissue is eliminated from the measurement, and as the real time display of the measured ultrasound waveforms allows for the operator to correctly position the sensor on top of the bone.
