Detachable multi-position ultrasonic bone strength instrument

Abstract

The invention discloses a detachable multi-position ultrasonic bone strength instrument, comprising an ultrasonic probe box and a detachable probe module, wherein multiple ultrasonic probes with different frequencies and different sizes are mounted in the ultrasonic probe box, the detachable probe module comprises a clamping device and a force sensor, the clamping device is used for mounting the ultrasonic probes, the force sensor is used for detecting the contact force between the ultrasonic probes and a measured position, the output port of the detachable probe module is connected with an integrated signal acquisition and processing module through a signal wire, and the integrated signal acquisition and processing module is in bidirectional connection with a man-machine interaction module. According to the detachable multi-position ultrasonic bone strength instrument, corresponding ultrasonic probes are mounted according to different to-be-measured positions of a human body, the center frequency and the size of each ultrasonic probe are set according to the specific measured position of the human body, so that the ultrasonic probes are matched with the measured positions reasonably, one bone strength instrument can simultaneously detect the bone strength of multiple positions of the human body, and the measurement result can indicate the overall bone strength of the human body more accurately.

Description

technical field [0001] The invention relates to the field of ultrasonic biological information acquisition, in particular to an instrument and method for ultrasonically measuring bone strength of human bones, specifically a detachable multi-position ultrasonic bone strength instrument. Background technique [0002] Skeleton is an important part of the human body, and bone quality is one of the important evaluation indicators of human body function. Currently, the clinically accepted method for detecting bone status is dual-energy X-ray absorptiometry (DXEA). However, due to the shortcomings of such equipment, such as bulky, expensive, and radiation, they are limited to professional hospitals, and it is difficult to carry out large-scale population screening and regular inspections. [0003] In recent years, quantitative ultrasound (QUS) measurement of bone strength testing technology has developed rapidly. Quantitative ultrasound mainly uses the propagation velocity and at...
