Abstract

The invention discloses a noninvasive ultrasonic bone mineral density measurement instrument which comprises an instrument body (1). The instrument body (1) is connected with a fixed measurement device (2) and a movable measurement device (3) through a switch (4). The fixed measurement device comprises sensors (21) which are arranged oppositely. A soft heat preservation bag (22) used for containing limbs is arranged between the sensors (21) and provided with a constant temperature heating device (5). According to the noninvasive ultrasonic bone mineral density measurement instrument with the technical scheme, the soft heat preservation bag is kept to be at the constant temperature when in operation, when the temperature of a bag body and the surface temperature of the limbs are the same after the limbs are placed in the soft heat preservation bag for a period, and the sensors which are arranged oppositely are moved to be tightly attached to the measured limbs to carry out measurement. Measurement errors caused by shell temperature are decreased, measurement is not affected by the shell temperature and is made to be more accurate, and the noninvasive ultrasonic bone mineral density measurement instrument is particularly suitable for measuring the bone mineral density of the calcaneus.

Description

technical field [0001] The invention relates to a bone density measuring instrument, in particular to a non-invasive ultrasonic bone density measuring instrument. Background technique [0002] The human skeleton is composed of many bones, and the functions of each bone are different. Whether it will affect the hardness of each bone, that is, bone density, and whether the bone density is normal or not can also be a sign of whether the bone is healthy, so bone density Measurement is important. The product can be widely used in national fitness examination, bone density determination of athletes, bone quality examination of middle-aged and elderly people, and numerous osteoporosis patients, which is of great significance. [0003] Ultrasonic measurement is used in the prior art, because it has no radiation and is more sensitive in diagnosing fractures, which has attracted widespread attention. The use of sound wave transmission velocity and amplitude attenuation can reflect th...
