IAPAPABA'IUS FOR PRODUCING HIGH-VOLTAGE CURRENTS. FOR MEDICAL TREATMENT.

Application filed Nov'ember 11, 1924. Serial No. 749,322.

To all/whom t may concern;

Be it known that I, ERICH Gnlssnnn, a German citizen, and residing at Munich- Laim, Germany, have invented certain new and useful Improvements in 'an Apparatus for Producing High-Voltage -Currents for Medical Treatment, of'which the following is a specification.

The hitherto known apparatus forl producing high-voltage currents for medical treatment 4are provided with a separate switching-on and adjusting devlce and can be used with special electrodes only. The adjustment'. of the intensity of current as well as the application of the electrodes to the human body is mostly much feared and irksome, because according toithe choice of the electrodes and with a strong adjustment of the current intensity burnings occur frequently, apart from breaks of the glass electrodes if using the same for treating inner parts of the human body.

The present invention overcomes said drawbacks by the provision of means for 2l permanently keeping the apparatus adjusted to a normal intensity of current and automatically eecting the closing of the circuit during its use. Thus, the admission of the high-voltage currents to the humanv i0 body takes place almost u nperceivably.

The automatic switching-on or closlng of the circuit is effected by the current applicator (button-shaped electrodes of lglass or metal), which is connected with the secondary (Tesla) coil in a detachable but conductive way. The closing of the circuit is effected by a depresison of the electrode by means of a human member or' by pressing the same against any place of the human body. Of course, the electrodecan also be operated in anyother way for switching-on the current or for a displacement of the secondary coil, for insta-nce by its'rotation, a lever transmission, or any vother appropriate mechanism As the electrode is connected with the secondary coil, thel latter is dis-l placed against the action'of springs and thereby the contacts, and thus the circuit,

are closed, whereupon the high-voltage cur- The advantages of the improved arrangement consist in avoiding errors of control 65 and thus the production of noxious currents and finally a formation of sparks: when applying the electrodes to the human body. The latter isalmost unperceivably. charged with currents of high-voltage, whereupon the members to be cured are treated directly or with the aid of any appropriate instrument by a second person Aconnecting himself to the circuit like a condenser and whereby at the place in question the current is taken from the human body.

Itan artihcialearthin'g is created, for in-A stance by Vleading back the electric current. to the condenser of the apparatus through va second electrode or instrument arranged in an insulated handle and in contact with the current-charged body, thecurrent receiving patient himself can also carry out the treatment of the respective places-on his own body. 75

For 'a removal of Warts, corns, beauty spots, or the like, no separate electrodes as hitherto are required, because any metal implement can be used for the purpose in question. Of course, also the known glass or .o metal electrode can be used for treating the human bodyat the places in question.

The apparatus essentially comprises av secondary coil, a primary coil, and a condenser; said parts being assembled in any appropriate shape, for instance in a box, tube, column, or the like, only the current supply and the electrode for switching-on the cur-- rent being visiblev from outside.

In the accompanying drawing, Figs. 1 to 0 3 show the apparatus shaped like a box, and Fig. 4'like a tube; Fig. l bein -a sectional side view on the line B-B of Fgig. 3; Fig. 2 a sectional side view at right angles to that of Fig. 1; Fig. 3 a sectional plan View on the line A-A of Fig. 1; and Fig. 4 a side View. Y

Referring to Figs. 1 to 3 inclusive: The apparatus is enclosed by a casing a. The secondary coil b consists, as usual, of a core c, the oilpaper coating d, with the secondary windings e, the glazed paste-board tube f, and the primary windings g leading at one end to the condenser It and at the other end to the interrupter (magnetic hammer break) i. The secondary coil b is slidably mounted on ins lc encircled by coil springs Z which ten to keep said coil in its inoperative position. A-metal disc m at the bottom end of the secondary coil is provided with one contact n; the other contact 0 being located underneath and connected -with the interrupt'er 'L'. The metal disc m is connected with the middle part of the three-part plug p, the three parts of which serve to use the apparatus for different current voltages. As

usual, of thevtwo remaining lateral plugs one is connected to the whole winding of the primary coil g and the other to part of said winding only. According to the current voltage in the line, the plug box cover connected with the. latter is attached to either of these two plugs fr.` l

The primary coil q-is of ordinary construction, the interrupterA 'L' being mounted thereon, the discs r arranged on the lat-ter serving as radiating coolers.

In the core c of the secondary coil b a sleeve s` is inserted and designed to receive the electrode shell tl, in which the electrode u is "-detachably inserted.

To make the apparatus operative, the electrode u, and thus also the secondary coil b,

is depressed against the action of springs Z, whereby the contacts n, o and thus the circuit are closed. By ceasing the pressure on the electrode, the circuit is again interrupted.

For an. auto-treatment, a second electrode or metal instrument /v is provided and arbody.

ranged on an insulated handle to, a wire m serving to lead back the current to the condenser h, said wire being connected thereto by means of a plug in order to be attached e voltage. currents fo'r medical treatment, the

combination with an electrode consisting of glass and forming a contact button, of

means for closing the circuit by pressing said contact button on part of the human 2. In an' apparatus for producing highvoltage currents for human cure; the combination with a casingv enclosing the apparatus and an .,electrode protruding from said casing, of means for automatically closing the circuit and again automatically interrupting the same by said electrode during use ofthe apparatus.

In testimony whereof I have hereunto set my hand.
