Definitions

  • High-frequency devices for therapeutic objects are already in use, in which a primary current of comparatively low tension is transformed with the aid of an interrupter and a condenser in a secondary of Tesla coil into a high-frequency current of considerable tension, which is discharged in a metallic electrode or in a glass electrode (under the effect of light, violet rays).
  • This 13 discharge acts on the part of the body to be subjected to treatment.
  • sparks will be formed which cause a painful sensation or burning.
  • FIG. 1 and 2 illustrate the regulating arrangement mounted on the apparatus in side view and front view respectively.
  • a cylindrical casing 1 consisting for in stance of ebonite, encloses an arrangement for producing the high-frequency current and is provided with two contact pins 2 and 3 for the connection of the primary tension and with a switch a for the primary tension.
  • the discharge member 5, consisting in the present case of an evacuated glass electrode, is placed with its surface 6 onto the place of the body to be treated.
  • the metallic sup' ort 8 is secured to insulating member 11hr means putting in circuit of a small screw 10, the said member forming a guide 12 for the movable contact member.
  • the latter consists of an angle bar, furnished with a horizontally disposed arm or branch 13 and a vertically located arm or branch 13", a tension spring 14 being attached to the lower end of the vertically located branch 13". The other end of this spring is hooked into a small pin 15, clamped in a strip 16.
  • a screw 17 By means of a screw 17 the latter is removably connected with the insulating member 11 and provided with a hole of semi-circular cross-section which, by means of a corresponding hole in the insulating member 11, completes itself to form a channel surrounding the tension spring 14.
  • the face of the insulating member 11, resting against the casing 1, is covered with feltpad 18 and by means of a belt 19 may be secured to the cylindrical casing 1.
  • the arrangement is used in the following manner i If the desired discharge current strength is reached after switching-on the primary current, the thumb of the hand holding the arrangement is placed onto the underside of the horizontally disposed arm or branch 13, which is formed with a protective face against the sparking current, andthe movable contact is moved in the direction of the arrow (Fig. 2), against the action of the spring 14, until it contacts with the fixed contact 9, the contact being kept up for some time, so that the greatest part of the high-frequency current from the electrode 5 passes over the metallic sleeve 7, the support 8, the contact member 9 and the mov able contact branch 13 into the hand or body of the person holding the arrangement.
  • New the electrode be lifted may treat (ill the place under treatment, without any undesi able spark-formation.
  • the essential advantage of the regulating arrangement according to the present invention consists in that alterations of connection are neither required in the primary circuit nor in the secondary circuit.
  • the pri- *nary current always acts with its full force, While the entire high-frequency current is turned aside. Destruction by the current or short circuit'in the arrangement, owing to interruptions or defects, is rendered quite impossible.
  • adischarge electrode In a high-frequency device for electromedical objects; adischarge electrode, and a Contact arrangement provided on the device the said arrangement comprisinga metallic conductor, oneen'd oi"? the later sur rounding thesaid electrode and the other end thereof forming a pole of the said arrangement.
  • a discharge electrode In a high frequenc v' device for electroinedical objects, a discharge electrode, and a contact arrangement provided on the device, the said arrangement comprising a metallic conductor. one end of the latter surroundingthe said electrode and the other end thereof forming a pole ot the said ar- 'rangeme'nt, and an adjustable pole adapted to cooperate with the pole first inentioner.
  • a discharge electrode and a contact arrangement provided on the device, the" said arrangement comprising; a metallic conductor, one end of the latter surroundingthe said'electrode and the other end thereof forming" a pole of the said arrangement an adjustable pole adapted to cooperate with the pole first mentioned and a spring secured to the adjustable pole and adapted to return the latter into the initial position.
