Description
Technical field
The present invention is about a kind of bone detection device and method, and especially, the present invention can also can detect the bone detection device and the method for the degree that gets loose of hip joint in order to detect the bone density of femur about a kind of.
Background technology
The function of skeleton comprises body support, protection internal organs, hemopoietic, adjusting mineral etc., is very important organs for the mankind.Yet, because be busy with one's work, factor such as life stress increase, make that modern's nutrient uptake is unbalanced, lack the motion of appropriateness simultaneously, cause the skeleton quality to descend.In addition, human skeletal's density peaked in the time of 30 years old, annual backward 0.3% to 2% the bone-loss that has approximately.Therefore, make regular check on instant discovery such as osteoporosis (Osteoporosis) just, problem such as osteonecrosis, degenerative joint and and early treatment or prevention become one of emphasis of physical examination.
In order to reach the purpose of checking bone density, many relevant devices and check system are developed, for example, X-ray examination, single photon skeleton density are measured (single photon absorptiometry, SPA), the two-photon skeleton density is measured (dual photon absorptiometry, DPA), CT Scan (computed tomograpy, CT), dual energy X-ray bone density check (dual energy X-rayabsorptiometry, DEXA) and ultrasound investigation or the like.
X-ray examination can only detect skeletal calcium content and reduce about more than 30% or situation such as fracture takes place, so more insensitive also inaccurate.The single photon skeleton density is measured or two-photon skeleton density mensuration then is that the energy photon that utilizes radiosiotope to discharge is measured bone density, but because the problem of half-life and stability, fewer being used at present.Though and the sensitivity of CT Scan and degree of accuracy are very high,, seldom be used because radiation dose and inspection cost are all high.
Ultrasound investigation is owing to have short, radiationless, advantage such as expense is cheap of review time, therefore be widely used, as Taiwan patent announcement number No. 144806 disclosed " method of ultrasonic analysis bone strength and device in the live body ", and Taiwan patent announcement number No. 492859 disclosed cases such as " ultrasonic bone assessment device and methods ", all belong to the application of ultrasound investigation.Yet the ultrasound investigation mode is subjected to the influence of skin, muscle or other soft tissue easily and produces error, influences the accuracy that skeleton density is measured.
In addition, the inspection of dual energy X-ray bone density becomes and is mainly used in one of instrument that bone density detects at present owing to having advantages such as the low and error of amount of radiation is little.Yet the required Measuring Time of DEXA is longer, and instrument is bulky, thereby has reduced portability and popularity.
In sum, have certain accuracy and safety, the development of bone density detecting instrument easily has its necessity.
Summary of the invention
Therefore, a category of the present invention is to provide a kind of bone detection device and method, and in order to detect the bone density of femur, especially, bone detection device of the present invention and method also can detect the degree that gets loose of hip joint.
A kind of bone detection device according to a preferred embodiment of the present invention comprises a vibration module, a multi-mode ultrasound examination module and a processing module.This vibration module is pressed close to a body end far away of a measured femur, imports a vibration signal in order to this body end far away certainly.This multi-mode ultrasound examination module is then pressed close to a near end of this measured's femur, detects this vibration signal in order to this near end certainly, and produces a detection signal.This processing module then connects this vibration module and this multi-mode ultrasound examination module respectively, in order to judge this measured's bone density according to this vibration signal, this detection signal and one first criterion.
A kind of skeleton detection method according to another preferred embodiment of the present invention comprises the following step: at first, import a vibration signal from a body end far away of a measured femur.Then, detect this vibration signal by multiple ultrasound examination pattern from a near end of this measured's femur, and produce a detection signal.At last, judge this measured's bone density according to this vibration signal, this detection signal and one first criterion.
