The use of ultrasound in the ultrasonic instrument
But if you buy this set of equipment have to learn to do before the use of some essential preparatory work, this is not a simple matter, the general operation of the ultrasonic induction instrument massage methods are in accordance with the following two steps The first step: deep clean the skin base from the chin to the ear first pull from the mouth to the ear pulling, pulling from the man to the ear. And then from the nose to the lower eyelid to the temple to pull from the frontal brow to the hairline up and down massage to the temple, from the chin, the mouth pulled to the nose, and then pull the lower eyelid to the temple and then from Chin pulled directly to the temple. Step 2: Ultrasonic Injector Nutrition Essence is imported from the chin to the ear, the spiral massage, the hand can increase the intensity of the mention, from the mouth to the ear, the hands of uniform strength, from people to the ear, from Nose under the eyelids to the temple. And then let the probe in the nose at the circle, under the eyelid when the intensity of the hand to ease the main to comfort, to the temple at the top of the pull can be slightly increased hand strength. And then from the frontal brow to the hairline up and down massage to the temple, the action on the slightly increase the intensity, the next move to appease the main, from the chin, the mouth pulled to the nose, and then pull the lower eyelid to the temple. Finally from the chin along the jaw straight pull to the temple, the left hand can follow a large area to move the probe, do the auxiliary push action.
③ thermal effect. As the ultrasonic frequency is high, energy is large, when the medium can absorb a significant thermal effect. ④ chemical effect. The role of ultrasound can cause the occurrence or acceleration of certain chemical reactions. For example, pure distilled water produced by ultrasonic treatment of hydrogen peroxide; dissolved in nitrogen water after ultrasonic treatment of nitrite; dye aqueous solution after ultrasonic treatment will discolor or fade. The occurrence of these phenomena is always accompanied by cavitation. Ultrasound can also accelerate the hydrolysis, decomposition and polymerization of many chemicals. Ultrasound also has a significant effect on photochemical and electrochemical processes. A variety of amino acids and other organic substances in the aqueous solution after ultrasonic treatment, the characteristic absorption spectrum disappeared with a uniform absorption, indicating that the cavitation effect of the molecular structure has changed.
