Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a portable ultrasonic bone densitometer. Background Technology

[0002] Human bone density peaks around age 30 and then gradually declines, leading to osteoporosis. Currently, my country has over 210 million people aged 60 and above, making it the country with the largest absolute number of elderly people in the world. With the increasingly serious aging population, osteoporosis has become one of the major diseases threatening the health and quality of life of Chinese residents, and is a public health problem urgently needing to be addressed. Osteoporosis patients have approximately a 40% lifetime risk of fracture. Furthermore, the medical treatment and care for osteoporosis and fractures require significant human, material, and financial resources, placing a heavy burden on families and society. Therefore, precise diagnosis and treatment of bone loss has significant social benefits. Current bone density tests and laboratory examinations can only reflect the overall bone calcium status of the body, and cannot accurately reflect the bone quality of key areas, nor can they enable timely treatment of fractures.

[0003] Patent CN103860203B discloses an integrated ultrasonic bone densitometer that embeds a tablet computer, color printer, ultrasonic probe, and drive controller into a single frame. This allows for ultrasonic signal detection, analysis, processing, and report printing, making it easy to operate and use. It is characterized by its small size and low power consumption, significantly reducing costs. However, the integrated ultrasonic bone densitometer disclosed in patent CN103860203B has multiple devices embedded in the frame, resulting in a complex structure that is difficult to adapt to various complex environments and is inconvenient to carry and transport. Furthermore, the ultrasonic bone densitometer only has a detection function and lacks ultrasonic-responsive controlled-release drug function, making it impossible to provide timely treatment based on test results. Its functionality is relatively limited, and it is inconvenient to use. Summary of the Invention
