Description
Technical field
The present invention relates to a kind of instrument that is used to measure bone mineral density, particularly a kind of probe of measuring bone mineral density.
Background technology
Osteoporosis is a kind of serious harm senior health and fitness's an insidiousness disease.China is the maximum country of aging population in the world, and the old people more than 60 years old has reached 1.3 hundred million, accounts for 10% of population, and elderly woman of China nearly 50% and 20% elderly men suffer from osteoporosis, and be very urgent to its control.
Be to adopt X-ray production apparatus to measure bone density in early days to Diagnosis of osteoporosis at present, though this instrument is succinct practical, it does not have quantitative function, and sensitivity is low.During the eighties, begin to adopt single photon absorptiometry instrument, as radioactive source, though that this instrument uses is fast and convenient, expense is low with americium, and it is only applicable to measure the less skeleton of surrounding soft tissue, Gu and higher rate of missed diagnosis and misdiagnosis rate arranged.Though it is good that a large amount of dual X ray borne densitometers that adopt of the nineties have accuracy, radiation dose is little, and advantages such as image resolution ratio height, handling safety, the price of instrument are very expensive, are difficult to popularize.Though the quantitative CT device measuring bone density of Chu Xianing has the degree of accuracy height subsequently, can separate the special performance of spongy bone and cortical bone, because of its radiological dose is big, Measuring Time is longer, and expense is obviously higher, and general hospital is difficult to popularize.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned existing measurement bone density instrument or degree of accuracy is low or radiological dose is big or cost an arm and a leg, the shortcoming of can not everyway taking into account.
The present invention is a kind of ultrasonic probe for quantitative measurement of bone mineral density, it by a measuring probe with lay respectively at two positioning probes measuring probe both sides, that structure is identical and form, described positioning probe is parallel with the measuring probe detection faces.
Described measuring probe and two positioning probe structure basically identicals, all constitute by shell and the probe core formed by delay block, wafer, absorption piece, Copper Foil and sound insulating layer, one of two wafer of described probe core are the emission wafers, one is to receive wafer, be separately fixed on the inclined-plane of two delay blocks, be Eight characters shape; The back side of wafer and side have Copper Foil and sound insulating layer with absorbing piece in the middle of two delay blocks, and Copper Foil, sound insulating layer and delay block are combined closely and be integral, and form the probe core, and the lead-in wire of wafer is connected on the socket of shell upper, is connected with gauge by socket.
The inclination angle of two delay blocks of described measuring probe is 55 ° ~ 65 °, two inclination angle opposite sign but equal magnitude, and wafer is that PZT is a lead lanthanum zirconate titanate (PLZT) electrooptical ceramics material, and frequency is 0.8～2.5MHz; 2 °～10 ° at the inclination angle of two delay blocks of positioning probe, two inclination angle equal and opposite in directions, direction are opposite, and wafer is that PZT is a lead lanthanum zirconate titanate (PLZT) electrooptical ceramics material, and frequency is 1.25～5MHz.
Positioning probe among the present invention is used to measure the skin soft tissue layer thickness and finally removes the measurement error that skin soft tissue is brought into, adopting two positioning probes is in order to make measuring probe keep balance, even the surperficial keeping parallelism of measuring probe detection faces and tested bone is to reduce measurement error.Measuring probe is used for measuring the spread speed of ultrasonic shear waves at bone, and the spread speed value of ultrasonic shear waves in bone can reflect bone mineral density information.
During use, the underrun couplant and the contact skin of described ultrasonic measurement bone mineral density probing shell, by positioning probe to skin soft tissue thickness measuring and balance after, the ultrasonic longitudinal wave of measuring probe emission wafer emission imports skeleton by couplant into through the skin soft tissue, on the interface between skin soft tissue and the bone wall, reflect, because wave mode is converted to ultrasonic shear waves, ultrasonic longitudinal wave in can not reflecting to the marrow, has been avoided the compressional wave noise jamming owing to total reflection.Ultrasonic shear waves reflects between key outer wall and skin soft tissue interface again to the reflection of bone inwall and obtains ultrasonic longitudinal wave, receiving wafer by measuring probe receives, by accurate measurement ultrasonic shear waves propagation time in bone, and then can calculate the spread speed of ultrasonic shear waves in skeleton, this speed is quantitatively relevant with bone mineral density, thereby reflects bone mineral density information.
The present invention adopts the quantitative ultrasound shear wave to detect bone density first, from a kind of new angle evaluation and test human body bone mass and bone density information.This sonde configuration is simple, and volume is little, degree of accuracy height, no ray, do not hurt body, the operation conveniently moving, low price has overcome the shortcoming of prior art, be suitable for popularizing, particularly suitable when human tibia detects especially, can be widely used in osteoporotic early diagnosis and generaI investigation detection.
