The development of ultrasound
Research on ultrasound began at the start of the First World War (1914), when the Allied forces used it to detect Germany submarines. Except for military purposes, it was only used for underwater research - until 1927, when the United States began to use ultrasound in bio-chemical research. In 1928, using ultrasoun, the eastern Germans ran experiments to attempt curing loss of hearing and otosclerosis, and by 1939, ultrasonic therapy was born. Although ultrasonic development was interrupted by the Second World War, the UK, among other countries, actively refined ultrasonic therapy for rehabilitative purposes in postwar years.
What is ultrasound?
Sound is transformed like a wave, with different sizes and densities; different waves emit high and low sounds. The human's hearing range is from 20 to 18000Hz. The higher the Hz is, the higher the tone we hear. Like the strings of a violin, the thinnest one always produces the highest sound. Ultrasound is undetectable to humans. In engineering, any rate over 20000Hz is called ultrasound, i.e. the threshold above 20000 vibrations per second.
To our hearing, ultrasound is inaudible, but to many animals, it is heard clearly. For example, a bat can respond to 20 thousands to 200 thousands Hz of ultrasound. A dolphin or whale can also discriminate between hundreds of thousands Hz of ultrasound. If ultrasound means nothing to our sense of hearing, what can we do with it? We can take the advantage of its density and speed in more subtle methods. First of all, we must know exactly how ultrasound can benefit us.
ULTRASOUND MASSAGERS FOR COSMETIC USE
ULTRASOUND MASSAGERS FOR BODY MASSAGE
INFRARED HEAT + ULTRASOUND
BODY MASSAGER HS3008R
Head size is over 2.5X that of a regular ultrasound head.
Thermal massage through absorption of ultrasonic energy to generate deep heat within body tissues
Mechanical massage (micro-vibrations)
Micro-vibrations induce changes in physiochemical processes of Biological components (fluids, absorption levels of membranes, uptake of nutrients, etc.)
ULTRASONIC Conductive Gel
Water soluble, chloride free, non-staining, non-irritating, greaseless, odorless.
Increases effectiveness of contact,extends life of head, promotes penetration of ultrasound.
The ultrasound massager emits a deep micro-vibration so rapid, that it cannot be seen or felt by the surface of our skin - so don't think your Ultrasonic Massager isn't working!
To test it, place a drop or two of water on the metal head of the Ultrasonic Massager, then press 'Power' switch to turn on. You will see how the water is broken into tinier and tinier droplets by the action of micro-vibration.
IN PROFESSIONAL THERAPISTS' HANDS
Ultrasound is often used by Chiropractors and Doctors with the aim of accelerating blood circulation in the local area, sport injury recovery, pain relief, reduction in inflammation and muscular spasms, and increased absorption of analgesics or anti-inflammatories.
Use 3 million vibrations per second to work on smaller muscles, such as those of the face.
1 MHz ULTRASOUND
FOR AVERAGE MUSCLES
Use 1 million vibrations per second to work on medium sized muscles such as in the limbs, neck, and shoulders...
0.5 MHz ULTRASOUND
FOR LARGE MUSCLES
Use 0.5 million vibrations per second to work on the largest muscles of the legs and back...
INFRARED CARE With penetrating infrared warmth, the metabolism of muscles is increased. The infrared function can be used to improve muscle tone during treatment.
Photon Beauty helps to revitalize cells, enhance blood circulation, increase oxygen supply, strengthen skin tissues and improve metabolism and excretion by using natural light waves that transmit into the skin and activate photoreceptor cells where energy is absorbed by skin components for a more beautiful complexion.
