Studies have shown that osteoporosis, which has always been regarded as a unique disease of the elderly in China, actually exists in childhood and has a causal relationship with many childhood diseases. Children who do not reach high bone mass in infancy may suffer from osteoporosis at an early stage even if there is no incentive to accelerate bone loss in the future. The fracture phenomenon in childhood is also related to insufficient bone mass and fragile bones. In particular, it needs to be emphasized that because there is no safe and effective radical cure in medicine to help loose and deformed bones recover completely, it is particularly important to correctly recognize and prevent them in the early stage. As the basic stage and starting point of human skeletal development, infants are particularly important in the guidance of growth and development. "Don't let children lose at the starting line", especially in the skeletal system that supports human physical development. With the in-depth implementation of the basic national policy of family planning in China, the health status of children has attracted more and more attention from the society. Osteopathy and its related nutrition and health problems have become a social topic, which has attracted the attention of experts and scholars and the attention of the government. Entering 2 1 century, China's population has reached nearly1300 million, and the number of skeletal patients has increased rapidly. It has become a serious public health problem in China. Therefore, how to effectively prevent, diagnose and treat osteoporosis and its early osteopenia, or carry out correct life care according to effective health judgment, and even use appropriate scientific means to improve the quality of life has become the research direction of many clinicians and epidemiologists. At present, more and more experts and scholars on children's diseases are focusing on the study of children's bone health, helping and guiding families to promote teenagers to reach the maximum bone mass, reducing the incidence of fractures in childhood and preventing the early occurrence of osteoporosis in adulthood. This requires a reliable diagnostic instrument, which can be easily applied to all kinds of research and measurement. This is the bone densitometer. These simple, economical and practical bone mass measuring devices have been recognized in medicine and widely used in clinic.
Osteoporosis involves a wide range of disciplines. From the aspects of bone mineral accumulation, bone growth and development, nutritional balance, etc. It belongs to the research field of pediatrics, especially the diagnosis and prevention of rickets, which is an important subject of children's health care. Because of its physiological particularity, pregnant women can easily become a group with reduced bone mass, and even affect the growth and development of the fetus, so the application of obstetrics in the health care of women of childbearing age is very important even before this. Everyone has a love for beauty, because children's skeletal dysplasia during their growth period affects the beauty of adults in the future, which no one wants to see. Judging from the relationship between the intake of protein and vitamin D deficiency and osteoporosis, it belongs to the category of nutrition research; Regular weight-bearing exercise and sunshine exercise can reduce and delay the occurrence of osteoporosis, which is closely related to sports medicine research; In addition, osteoporosis is also related to genetics, biomechanics, biochemistry and molecular biology. In a word, because the inducement of osteoporosis involves a wide range, it will be very beneficial to health prevention if a personal file of bone changes can be established.
Osteoarthropathy is a group of diseases with rapid growth, serious harm, huge cost and obvious influence on people's quality of life worldwide, and has become one of the international research hotspots. The World Health Organization put forward "Ten Years of Osteoarthropathy from 2000 to 20 10", aiming at attracting the attention of doctors and people all over the world and strengthening the effective prevention and treatment of such diseases. The International Osteoporosis Foundation has also released corresponding publicity materials on children's bone health, and issued an initiative of "investing in your bones" to the public. In the future, human beings should live a healthier life.

Introduction of characteristics and performance of CM-200
Detailed description of serial number performance characteristics
1 The machine is imported from Japan, with excellent design, beautiful appearance, lightness and convenience, and simple operation.
2 Use the safest measuring medium-ultrasound is a measuring medium without radiation hazard, so doctors don't need to consider protection. Even pregnant women can use and operate with confidence. So it is the first choice tool for physical examination and portable use.
3 The best ultrasonic detection site for bone and bone structure changes-calcaneus The bones of human body include cortical bone and cancellous bone. Anatomically, cancellous bone is rich in osteoblasts and osteoclasts related to bone regeneration and aging. It is generally believed that osteoporosis first occurs in cancellous bone and then manifests itself in later cortical bone. Therefore, it is more necessary to measure cancellous bone than cortical bone when measuring bones, and WHO is also the gold standard site for measuring bones. Some data show that the measurement level of calcaneus is equivalent to that of femoral neck. For the ultrasonic measuring instrument, the selected part should meet the following three conditions: first, "skin and bones", that is, contact with the surrounding soft tissues as little as possible to reduce the interference of soft tissues on the measurement; Second, the content of cancellous bone should be as high as possible. Third, it should be the load-bearing bone of the human body. Generally speaking, the bones of limbs meet the first condition, the bones of lower limbs meet the third condition, and the calcaneus (more than 90%) is the highest in the bones of lower limbs. Its physiological tissue structure determines that it is the most sensitive part of limb skeleton to reflect bone changes, and there are relatively few surrounding soft tissues, which is convenient for testing and easy for patients to accept.
4 Full-dry measurement method Comfortable ultrasonic measurement method-more convenient and faster to use, no need to connect any water supply and drainage system, no troublesome cleaning work, and interference signals generated by microbubbles in water.
5. The built-in national standard reference database of China is a degenerative disease. Generally speaking, primary osteoporosis is closely related to people's living environment and genetic factors, so people's bone condition is closely related to their growth and development environment. According to WHO diagnostic criteria, T and Z values are comparative parameters, and their accuracy depends on the accuracy of the database. So for bone mass detection, the standard database is not good for large areas, but more accurate for local areas. The database used by CM-200 was released by dozens of authoritative experts from Bone Mineral Research Branch of Chinese Medical Association after collecting data from many domestic centers. It should be the latest published China ultrasound standard bone database, which is the first and only set of all-China bone database established by authoritative experts of Chinese Medical Association. It is the most suitable for the present situation of China people, and the diagnosis results obtained from it should also be the most accurate, so as to correct the deviation formed by the skeletal data of other human populations in time, and the obtained T value and Z value are reliable.
Multi-system operation mode, single machine operation-portable design, convenient installation, simple and fast visit and physical examination. The built-in thermal printer can print the report immediately and quickly, and the external measurement data can be manually added to the database if necessary. Single-machine measurement can also be carried out by gender, which is the only one of all models that can be measured by single machine at present, so that both men and women can measure according to their own physiological curves, and men no longer refer to the female database.
Operation of the whole machine-the workstation is equipped with a special system, which can be desktop or portable, and is equipped with a well-designed system platform for doctors to make detailed diagnosis, generate formal clinical reports in color Chinese and carry out various research projects.
The software of the ad hoc patient data management system has a unique data management platform, which can be perfectly managed whether the data is imported from the computer or entered into the database off-line. Users can establish their own database according to their own special conditions, which is convenient for clinical case statistics, filing, research and writing papers. Monitor the influence of diseases and drugs on bone mineral density in time, analyze the regularity and trend of patients' bone condition changes, and provide reliable detection basis for clinical research and diagnosis.
The purpose of parameter setting test is direct, giving up all unreliable and repeated parameter testing and calculation. At present, international authorities in the field of osteoporosis treatment have recognized that SOS is the most effective and comprehensive indicator in ultrasonic diagnosis of osteoporosis, and almost all the bone changes that can be detected can be reflected on SOS. It is found that the accuracy of SOS in diagnosing bone status is significantly higher than other parameters.
9. The color LCD screen displays all operating interfaces in Chinese, and after professional translation, it forms its own unique and detailed Chinese diagnosis report. Clear, clear and colorful, so that the operation and results are clear at a glance. At the same time, it can also display the precision management state of the instrument completely.
Correlation between 10 and gold standard of bone mineral density detection. At present, the World Health Organization's temporary diagnostic standard for bone mineral density detection is DEXA measurement based on lumbar vertebrae, and all other detection methods must ensure that they have certain correlation with this standard. Among ultrasonic testing instruments, CM series has the best correlation, which has been studied, compared and tested by experts and professors (proved by papers published internationally).
The measurement time of 1 1 is very short, only 10 second-showing extraordinary simplicity and rapidity. It is most suitable for children's physical examination, general survey and other occasions with difficult detection and concentrated workload. The measurement time of Guye bone densitometer is less than 10 second, and it is generally less than 30 seconds if pre-preparation and post-processing are added. If it is a single machine, the general traffic can reach 15 seconds -20 seconds/bit, and any unwilling child can successfully complete it.
12 the original temperature compensation system will form the microstructure of the object due to temperature, which will cause temporary stress response and directly affect the measurement accuracy. Otherwise, the measurement result of this machine will be doubted. If the heel is heated, the measuring time will be too long, or the measuring part is not heated enough, which will affect the accuracy. The temperature compensation method is the most advanced (first published at the 8th International Osteoporosis Conference in September 2008).
13 can be equipped with infant measurement module CM-200 and 0-8 years old child measurement module, which fully meets the requirements of infant health assessment and has low measurement requirements, making this method more suitable for active and active infants. Moreover, the module components are automatically switched with the adult measurement software, only the date of birth needs to be input, and the system automatically chooses to switch, which is convenient for doctors to operate.
14 positioning system CM-200 is designed, calculated and configured with intelligent mechanical foot shape adjustment structure according to anatomical principle, which can automatically aim the ultrasonic beam at the best calcaneus measurement area, and because the position of the foot platform is adjustable, it is suitable for measuring a wider range of people with better repeatability and accuracy.
15 is suitable for visiting and getting off the ward.
16 It can be used by almost all departments in the hospital who want to know the patient's bone condition, such as orthopedics (including osteoporosis), gynecology, obstetrics, child care, endocrinology, geriatric diseases, rehabilitation physiotherapy, sports medicine, health examination center, prenatal special examination, drug treatment analysis, community service, etc.
17 Reasonable hardware design The whole machine design of CM-200 is more humanized, and the measured part of the machine body is low and flat, which is suitable for the elderly, children and patients with difficulty in standing. Consumable parts are not produced during normal use, which completely eliminates the subsequent burden of the hospital.
