Diathermy definition, the production of heat in body tissues by electric currents, for therapeutic purposes. See more. A diathermy apparatus includes a power oscillator for developing signals which are coupled to a patient by a tuned reactive coupling circuit. The magnitude of the oscillator signal is detected in the oscillator output circuit, and a corresponding control signal is developed. A reference signal is supplied by an output level selection circuit. George A. Williams, Thomas M. Aaberg Jr, in Retina (Fourth Edition), Diathermy. Diathermy is produced by high-frequency, MHz, alternating electrical current that generates heat because of the impedance (resistance) of the tissue through which it is passed. The heat created by the diathermy energy coagulates tissues. The histologic picture seen after diathermy depends on the. Diathermy uses electric current to generate heat in the body. The heat can help increase blood flow, relieve pain, and improve inflammation. Learn more.
Short-wave diathermy. Short-wave diathermy uses an oscillating electromagnetic field of high frequency to heat body surface areas. It heats to a tissue depth of 2 to 3 cm. Despite gradual decline in its use, short-wave diathermy still finds its place in treatment of large-surface body areas, such as lower extremities, upper extremities, and back. Physical principles. Radio frequency (RF) surgical diathermy or electrosurgery uses the heat generated by an electric current, 1 often delivered at more than V, passing through a small amount of tissue to cut, destroy or vaporize that tissue and to create haemostasis by causing coagulation and sealing of small blood vessels. Passing an electric current through the body causes all the. Book traversal links for Alternating Current a portable diathermy apparatus. This small set by the McIntosh Electric Corporation, Chicago (ca. ) was used by physicians with any number of hand-held attachments to treat various parts of the body. The Commission found it necessary to impose strict restrictions on the manufacture and use of medical diathermy apparatus because such equipment was interfering seriously with radio communications, including television. During the war, this type of interference was a major problem. Since a diathermy unit is a radio transmitter, the energy used.
The high-frequency machine may be used, in place of the diathermy apparatus, if the latter is not available. The vacuum electrode is connected to one end of the solenoid and the other end of the latter is connected to a metal rod which is grasped by the patient. Get this from a library!
