How to use ultrasound
Ultrasound is a sound wave with a frequency higher than the human hearing range and is widely used in medical, industrial, cleaning and beauty fields. This article will introduce in detail the use methods, application scenarios and precautions of ultrasound, as well as the hot topics and hot content in the past 10 days.
1. Basic principles of ultrasound
Ultrasonic waves refer to sound waves with a frequency higher than 20kHz. They are characterized by strong directionality and penetrating power, and can be detected or processed without damaging the medium. The application of ultrasonic waves is mainly based on its physical properties such as reflection, refraction and absorption.
2. Main application areas of ultrasound
| Application areas | Specific use | Example |
|---|---|---|
| medical | Diagnosis and treatment | B-ultrasound examination, ultrasonic lithotripsy |
| Industry | Non-destructive testing | Metal flaw detection, thickness measurement |
| clean | Precision cleaning | Jewelry and glasses cleaning |
| Beauty | skin care | Ultrasonic introduction instrument |
3. How to use ultrasound
1.medical field: Ultrasound is mainly used in medicine for imaging and treatment. During use, the probe needs to be coated with couplant, move it close to the skin, and generate images through reflected waves.
2.Industrial field: Industrial ultrasonic equipment is often used to detect internal defects in materials. During operation, the probe needs to be pointed at the object to be measured, and the internal structure is analyzed by receiving reflected waves.
3.Cleaning area: Ultrasonic cleaning machine generates tiny bubbles through high-frequency vibration to remove stains. When using it, you need to put the items into the cleaning tank, add cleaning fluid, and set the time.
4.beauty field: Ultrasonic beauty instrument promotes the absorption of skin care products through high-frequency vibration. When using, apply the medium on the skin and move the probe gently.
4. Hot topics and content in the past 10 days

5. Precautions when using ultrasound
1.safe operation: Avoid long-term exposure to high-intensity ultrasonic waves, which may cause harm to the human body.
2.Equipment maintenance: Check the probe and circuit regularly to ensure the normal operation of the equipment.
3.Environmental requirements: Some ultrasonic equipment needs to be used under specific temperatures or humidity.
4.Professional training: Users in medical and industrial fields require professional training.
6. Future development trends
Ultrasonic technology is developing in a more precise and intelligent direction. For example, ultrasonic equipment in the medical field will achieve higher resolution imaging, and detection accuracy in the industrial field will be further improved. At the same time, with the integration of artificial intelligence, the automation level of ultrasound equipment will also be significantly improved.
Summary: Ultrasound is a versatile technology with an ever-expanding range of applications. Proper use of ultrasonic equipment can not only improve work efficiency, but also bring convenience to life. In the future, with the advancement of technology, the application scenarios of ultrasound will be more extensive.
