Description

Ultrasound therapy device for skin and fascia and its operation method {ALL-IN-ONE ULTRASONIC THERAPY APPARATUS FOR SKIN AND FASCIA AND THE OPERATION METHOD THEREOF}

The present invention relates to an ultrasonic therapy device for skin and fascia and a method of operating the same, and more specifically, to providing customized stimulation of ultrasonic therapy to the inside of the skin raised (Up-Lifting) by a massage roller arranged in a Y shape. It's about devices.

The surface of the human body is made up of skin, fat, fascia, and muscle. Among these, the fascia surrounding the muscles is usually located at a depth of 4.5 mm from the surface, and is an elastic horizontal/vertical net tissue made of collagen as the main ingredient and plays an important role in maintaining the body. do. If the muscle becomes inflamed, the muscle and fascia become adsorbed, and relative displacement due to contraction and relaxation of the muscle cannot be provided, resulting in pain.

At this time, the treatment method is oriental cupping therapy, which lifts the skin and fascia with negative pressure using a vacuum cup to relieve adsorption of the fascia and muscles and helps relax the fascia. Additionally, in oriental acupuncture (Acupuncture), the tip of the needle is inserted into the fascia and then rotated to roll up the elastic net structure of the fascia, helping to relax the adsorption on the muscle. In addition, the massage action of the Y-shaped roller is known to roll the surface of the human body consisting of skin, fat, fascia, and muscle while simultaneously raising the skin/fascia to improve blood flow and relax the fascia from the muscles.

Meanwhile, there is an existing experiment that combines focused ultrasound energy with oriental acupuncture to irradiate fascia or capillaries to increase blood flow, and the effect has been proven. At this time, the skin absorption rate of ultrasound energy varies depending on the frequency. High frequencies are well absorbed but have a thin penetration depth, and low frequencies are poorly absorbed and have a deep penetration depth. In general, ultrasound for a fascia thickness of 4.5 mm is usually around 4 MHz. I am using it.

Therapy devices incorporating ultrasonic energy are being released for home or hospital use. However, for home use, two types of low-frequency ultrasound, 1 MHz or 3 MHz, are mainly used, and since it uses a single channel ultrasound beam, its effectiveness is limited for home users.

On the other hand, hospital use mainly uses low-frequency (1 MHz or 3 MHz) and high-frequency (7 MHz) ultrasound, and uses multiple channels of ultrasound beam, so it has the advantage of controlling the focus of the beam tailored to each user's skin depth. exist. However, the so-called High Intensity Focused Ultrasonic (HIFU), which is mainly used in hospitals, is expensive, and users have the inconvenience of having to visit the hospital for treatment.
