RARE EARTH USED IN MEDICAL TREATMENT
The application and theoretical problems of rare earth in medicine have long been the research project of the world. The pharmacological action of rare earth has been discovered very early. The earliest application of cerium salt in medicine, such as cerium oxalate, can be used to treat oceanic dizziness and pregnancy vomiting.
In addition, simple inorganic cerium salt can be used as wound disinfectant. Since the 60 s have found that the effects of the rare earth compounds has a series of special effect, is a good antagonist, Ca2 + has calm analgesic effect, can be widely used in the treatment of burns, inflammation, skin disease, such as thrombosis, which has attracted widespread attention.
The application of rare earth in medicine
1. Anticoagulant action
2. Burns medicine
3. Anti - inflammatory, bactericidal action
4. Antiarteriosclerosis
5. Radionuclides and antitumor
The application of rare earth in medical devices
In terms of medical apparatus and instruments, with containing rare earth materials of laser knife can make fine surgery, made of lanthanum glass optical fiber can be used as a light pipe, use it can be clearly observed in human gastric lesions, rare earth element ytterbium brain scans as potions, can be used to scan and chamber brain imaging; Made a new type of rare earth fluorescent material X-ray intensifying screen, compared to the original use of calcium tungstate intensifying screen shooting 5 ~ 8 times higher efficiency, and can shorten the exposure time, reduce the human body by radiation dose, shooting has been greatly improve clarity, apply an appropriate amount of rare earth screens can put the original a lot of difficult to diagnosis of pathological changes more accurately diagnosed.
Use of rare earth permanent magnet materials made of magnetic resonance imaging (MRI) is a new technology applied in the eighty s medical equipment, which USES a large steady uniform magnetic field a pulse wave to human body, make human body produce resonance h ydrogen atom and absorb energy, then suddenly closed magnetic field, the release of the h ydrogen atoms will absorb energy, as the h ydrogen distribution in the human body each organization is different, releasing energy of different length of time, through electronic computer received different information analysis processing, can recover the settlement precipitation images of the internal organs, to distinguish the normal or abnormal organs, identify the nature of the lesion.
Compared with X-ray tomography, MRI has the advantages of safety, painless, no damage and high contrast. The emergence of MRI has been described by the medical community as a technological revolution in medical history.
The most widely used medical application is the use of rare earth permanent magnetic material for the magnetic hole therapy. Because of rare earth permanent magnet magnetic is very high, and can make various shapes of magnetic therapy apparatus, and is not easy to demagnetization, effects on the body meridian acupoints with it or the lesion area, can be achieved than traditional magnetic therapy efficacy with good effect.
Now with rare earth permanent magnet material, magnetic therapy necklace, magnetic, magnetic health care magnetic bracelet earrings, fitness, magnetic cup, magnet and magnetic magnetic wooden comb, magnetic knee, shoulder, magnetic belt, magnetic therapy products, such as magnetic massager has sedative and analgesic, anti-inflammatory, relieving itching, step-down, anti-diarrhea effect.
