High Frequency Apparatus Page 117

PHYSICIANS' PORTABLE APPARATUS 117 This outfit is capable of doing all manner of general high frequency and X-ray work that may come within the requirements of treatment at the patient's bedside. The various modalities can be obtained from the equipment as follows: Static spark, vacuum electrode, fulguration or convective discharge, high frequency spray or effleuve, Oudin, Tesla and D'Arsonval currents, unipolar current, cautery current, ultra-violet lamp (from alternating current circuits only), and currents for auto-conduction and auto-condensation, sufficient for all local treatments. In addition to this, the apparatus is capable of giving very good results in X-ray work of the lighter type such as making radiographs of the extremities, fluoroscopic examinations for diagnosis in cases of fracture, etc. The outfit combines both a transformer and kicking coil. The former is used on alternating current circuits and the latter on direct. The operation is controlled by means of a few switches and levers and simplicity is a characteristic of the equipment.
