- What exactly does that layer of gel do?
B-ultrasound is a physical examination item that uses ultrasound to know the problems of the substantive organs of the body. Many people have done B-ultrasound, and many people find that the doctor will apply gel on the examination site before doing the B-ultrasound, and even pregnant women will also apply it. layer of gel. Some people are more disgusted with this layer of gel, thinking that it is sticky and sticky, and they are also worried about their body and want to refuse. But in fact the gel is applied before the test to get more accurate results.
- Can I skip the gel before doing a B ultrasound?
B-ultrasound is an inspection project through ultrasound, and ultrasound is a substance that does not cause any damage to the body. Even pregnant women can use B-ultrasound for multiple inspections. During the inspection, the B-ultrasound probe needs to be placed on the abdomen, so that the ultrasound penetrates the object to generate echoes to reveal the problem. Obstacles with different densities and thicknesses respond differently, resulting in different results. However, B-ultrasound has shortcomings and cannot be directly placed on the human body for inspection, because there is a thin layer of air between the probe and the human body. The density and thickness of the air and the human body are different, which will cause certain obstacles. If the probe is placed directly on the body On the other hand, when the ultrasonic wave comes into contact with the air, it will be strongly reflected, so it cannot be imaged, and the disease cannot be judged. Therefore, in order to help B-ultrasound imaging, it is necessary to apply a gel at this time, which is called an ultrasound coupling gel in medicine.
- What does the ultrasonic coupling gel do?
Ultrasound coupling gel is a substance most similar to body tissue, which can eliminate air interference to the greatest extent and make images clearer and more accurate. The body can be sticky and slippery when the gel is applied, because the probe needs lubricity to move freely on the surface of the skin. If the couplant is sticky, the probe cannot move on the body, which can lead to skin damage. Moreover, the time required for B-ultrasound is different for different patients, and some take a long time. At this time, if the couplant can be kept lubricated for a long time, it can minimize the influence of B-ultrasound results.
The couplant is not a drug, so it is safe. Its main purpose is to help the probe check better. Once the inspection is done, just wipe the couplant off with a tissue.
Kind tips
Ultrasound couplant will not affect your body, so you can rest assured. Don't worry too much about the entanglement before the B-ultrasound, just do the precautions before the examination, especially for pregnant women, to avoid filling the bladder in the early pregnancy examination to make the examination more accurate.
