The utility model relates to the technical field of portable medical devices, in particular to a portable handheld ultrasonic bone density meter.

Bone mineral density is an important index of bone strength. Human bone mineral content is closely related to bone strength. Therefore, bone mineral density is also an important index to reflect human health. With people's attention to health, measuring bone mineral density has become a routine examination in physical examination. There are many methods of measuring bone density, of which ultrasonic bone density measurement method is the most widely used, safest, fastest and most accurate. Ultrasonic waves have good directivity and strong reflectivity, and their propagation speed is different in different media. The principle of ultrasonic bone mineral density measurement is to calculate the bone mineral density value by the different propagation speed of ultrasound in bones with different bone mineral density.

Compared to the products known from the prior art, the embodiment of the invention has two significant technical improvements. First, the conventional ultrasonic bone densitometer considers that the attenuation of ultrasound in the bone is very fast, so an emission scheme is adopted where a unipolar pulse high voltage is over 300V. Such a high voltage poses a certain risk to the human body. The present embodiment uses the high voltage bipolar pulse emission scheme to control the high voltage within 80V. Bipolar emission has no zero screen and higher energy efficiency. Therefore, it can compensate for the ultrasonic attenuation caused by insufficient high voltage.

The traditional first-wave detection of bone mineral density with ultrasound, the sound velocity calculation and the filter design are implemented in software. The amount of data transferred between the prior art device and the host computer is large, which is not suitable for wireless transmission. The subject embodiment implements first wave detection, speed of sound calculation, and filter design on one hardware system. Only the ultrasonic velocity measured value needs to be uploaded directly to reduce the amount of data transmitted. In this way, said computer only has to complete the interface and patient management. The device is more convenient to use due to the wireless transmission. This wireless data transmission mode is easier to combine with internet-based mobile medicine. The invention can replace conventional medical equipment in the relevant departments of maternal and child hospitals. It can also be used as an innovative medical product in primary health centers, community clinics, pharmacies, general practitioners and other application scenarios.

The above shows and describes the basic principle and preferred embodiments of the utility model and the advantages of the utility model. Those skilled in the art understand that the utility model is not limited to the above embodiments. The above embodiment and descriptions only illustrate the principle of the present utility model. Without departing from the spirit and scope of the utility model, the utility model includes various changes and improvements. These changes and improvements fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the appended claims and their equivalents.
