[Function of Ultrasound Therapy Apparatus] The working principle of Ultrasound Therapeutic Apparatus How to use the Ultrasound Therapy Apparatus
The unique curative effect of ultrasound technology in medical treatment has been widely accepted in the medical field It is recognized and increasingly valued and adopted by the clinic. Medical experts at home and abroad have achieved very good results in the treatment of limb soft tissue injury, limb chronic pain rehabilitation, and limb movement rehabilitation using ultrasound technology, and have extended ultrasound therapy to traditional Chinese medicine, orthopedics, surgery, internal medicine, pediatrics, oncology, Andrology, obstetrics and gynecology, etc., have been widely used in clinical, and achieved satisfactory therapeutic effects.
The role of ultrasonic therapeutic apparatus
1. In traditional Chinese medicine: by using the thermal effect and mechanical effect of ultrasonic waves and super penetrating ability , so that when the ultrasonic wave acts on the acupoints of the human body, it can be comparable to the equivalent effect of acupuncture and moxibustion in traditional Chinese medicine.
2. In the treatment of soft tissue injury and chronic pain, the super penetrating power of ultrasound can improve the permeability of the cell membrane at the treatment site, improve blood circulation, and promote the occurrence and development of the cell repair process; at the same time, The human neurohumoral system has a strong sensitivity to the effect of ultrasonic waves. The neural reflexes and humoral responses formed by it have a mechanism to comprehensively regulate the human body, especially for old injuries. When the ultrasonic wave propagates, the direction of the ultrasonic energy is concentrated. , with unique high-energy properties. to achieve the purpose of treatment.
3. In the rehabilitation of limbs, ultrasound can improve microcirculation, improve blood supply around the lesion, stimulate mast cells to release chemokines, promote the accumulation of phagocytes at the lesion site, enhance phagocytic function, dredging blood vessels, active The purpose of establishing collateral circulation. Promote the blood supply of the affected limb, improve the microcirculation, promote the establishment of lateral circulation, and relieve pain.
4. In surgery: Ultrasound has a good therapeutic effect on the prevention and treatment of surgical complications, preoperative preparation and postoperative rehabilitation.
5. In orthopedics: the ultrasonic therapeutic apparatus can precisely treat the target site of focal disease, strengthen the local target site with systemic drug therapy, and synergistic treatment before and after surgery through the thermal effect and physicochemical effect of ultrasound. , with physical therapy treatment.
6. Internal medicine: on the basis of systemic drug administration, local ultrasound drug introduction synergistic therapy is given to improve the curative effect and shorten the course of treatment.
Usage of Ultrasound Therapy Apparatus
Fixing method. For patients with facet joint pain, the probe can be fixed on the painful area for treatment. It is characterized by easy operation and small dose (less than 0.6 watts per square centimeter).
Movement method. It is a method of continuously moving the probe on the painful joint for treatment. The mobile method is suitable for a wider range of pain, and the dosage is also larger. In addition, various methods such as underwater method and sound transmission method are available, but the fixed method and the mobile method are the most commonly used treatment methods. The treatment method of osteoarthritis patients should expose the painful joint, and apply a contact agent on the site (the role of the contact agent is to eliminate the air between the probe and the skin, so as to facilitate the passage of sound energy and reduce the progenitor of sound energy. loss), and then place the probe against the skin surface and determine the treatment dose and treatment time. For larger areas of pain, the probe can be moved continuously. The moving speed of the probe is 0.1 to 1 cm per second, and the moving speed should be as uniform as possible. When the treatment dose is large, the probe should not stay in one position, so as not to make the patient feel bad.
Why do I have to fast for an ultrasound?
Not all ultrasound examinations require fasting, only abdominal organs such as liver, gallbladder, pancreas, spleen, kidneys, abdominal blood vessels, lymph nodes, etc., as well as gastrointestinal ultrasound examinations are performed It is necessary to fast for more than 8 hours in order to reduce the interference of chyme and gas in the gastrointestinal tract and improve the imaging quality. For patients with frequent abdominal distension, it is recommended to have a light diet the night before the examination and take appropriate amount of digestion-promoting drugs before performing an ultrasound examination. In addition, the contraction of the gallbladder becomes smaller after eating, and it is difficult to distinguish whether the gallbladder is a physiological or a pathological change, and it also affects the display of lesions in the gallbladder cavity.
The working principle of the ultrasonic therapy apparatus
Under the condition of the same amplitude, the energy of an object vibrating is proportional to the vibration frequency, and the ultrasonic wave propagates in the medium When , the frequency of the medium particle vibration is very high, so the energy is very large. In the dry winter in northern my country, if the ultrasonic wave is passed into the water tank, the violent vibration will break the water in the tank into many small mist droplets, and then use a small fan to blow the mist droplets into the room, which can increase the indoor air humidity. This is how ultrasonic humidifiers work. sore throat. In diseases such as bronchitis, it is difficult for medicines to blood flow to the affected part. Using the principle of a humidifier, the liquid medicine is atomized and inhaled by the patient, which can improve the curative effect. Using the huge energy of ultrasound can also make the stones in the human body do violent forced vibration and break, so as to alleviate the pain and achieve the purpose of curing.
