The last manufacturer of violet ray electrotherapy devices in the US was Master Electric. The company was subjected to a 1951 lawsuit in Marion, Indiana, and the devices were seized by the FDA. [9] While their manufacture was prohibited in the US by case law, violet ray electrotherapy devices are still manufactured by companies outside of the US.
A portable Faradic battery by Philip Harris & Co. from 1913. A Faradic battery (or Faradic stimulator, or galvanic battery) was a device used in 19th and early 20th century medicine.
Electrotherapy is the use of electrical energy as a medical treatment. [1] In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. [2] Electrotherapy is a part of neurotherapy aimed at changing the neuronal activity. [3]
Oudin coil used for medical electrotherapy, 1907, and a schematic diagram of its circuit (left).. An Oudin coil, also called an Oudin oscillator or Oudin resonator, is a resonant transformer circuit that generates very high voltage, high frequency alternating current (AC) electricity at low current levels, [1] [2] [3] used in the obsolete forms of electrotherapy around the turn of the 20th ...
The "electric bath" (or "electrotherapy") aboard the Titanic, illustration from 1912. This facility was placed near Titanic's water pool and the Turkish baths, on F deck. Bird's most common use of the electric bath was to use the electric charge on the patient to draw off sparks by placing another electrode near the point of treatment.
At first, there was a very positive reaction to Pulvermacher. Early in 1851 Pulvermacher gave Golding Bird, a well known London physician with an interest in electrotherapy, a sample of the machine with which to experiment. Bird was impressed enough with it that he later gave a representative of the Pulvermacher Company a testimonial as a ...
It took many years for brief-pulse equipment to be widely adopted. [23] In the 1940s and early 1950s, ECT was usually given in an "unmodified" form, without muscle relaxants, and the seizure resulted in a full-scale convulsion. A rare but serious complication of unmodified ECT was fracture or dislocation of the long bones.
One of the oldest and best-known coils still in operation is the "GPO-1" at Griffith Observatory in Los Angeles. It was originally one of a pair of coils built in 1910 by Earle L. Ovington, a friend of Tesla and manufacturer of high voltage electrotherapy apparatus.
