Definitions

  • the invention relates to an apparatus, which enablesinternalpartsofthebodytobesubiected to the action of rapid, artificially produced cathode rays, 1. e., very rapid electrons, permit- 6 ting either of the suppression of growths, particularly those of a malignant kind, or also of the extermination of bacteria or germs.
  • cathode rays 1. e., very rapid electrons
  • there have been employed for this purpose primarily x-rays or the gamma rays of radium.
  • cathode rays-X-rays-secondary electrons 1. e., by the roundabout way cathode rays-X-rays-secondary electrons. merely quite a small proportion of the cathode rays amounting to between 0.1 and 0.001
  • the passage furnished in accordance with the invention is preferably constructed in the form of an extension to the discharge space of the cathode ray tube. If desired, the same may be removed and replaced by another fitting of difpotential apparatus is naturally very compliferent diameter and length.
  • the wall of the passage preferably consists of a highly atomic material, for example a metallic pipe.
  • the passage may be constructed on the lines of the known probing instruments for introduction into i cavities in the body.
  • the passage may be constructed in the form of an injection device, such as used in the medical andsurgical art for injection into the body.
  • the passage is movable in relation to the 10 discharge tube, and if desired may also be bent in form. This is accomplished by providing between the passage and the discharge tube a movable metal tubing, for example a tombac tube.
  • the tombac tube is then connected with the disll charge tube and the passage, for example by soldering. In this manner'the extension member is provided with the movability necessary for medicinal purposes.
  • the proce- 10 dure Upon the treatment of a patient, the proce- 10 dure, for example, will be such that at first a canula or a probe of the requisite dimensions is introduced into the cavity or the interior of the body, and it is only after this has been done that the projecting end is connected with the dis- 28 charge tube through the medium of a movable intermediate member. The treatment may then commence.
  • the passage In the space of the passage there may be generated longitudinal or transverse magnetic l0 fields, for example by the winding of a solenoid spiral, which fields ensure a guiding of the electrons as far as possible in the axis of the passage, even upon movement and bending of the passage.
  • the magnetic field does naturally not require to fill out the passage over its entire length, and it is sufiicient if the magnetic fields are present at the points of the bends.
  • a magnetic field which preliminarily concentrates the stream of electrons, in order that maximum surface intensities may be obtained.
  • the passage also requires to be insulated against the discharge tube by means of one or more insulating tubes.
  • the passage tube itself may be so constructed that no electrons are able to emerge at its jacket surface, the end of the passage is sealed by a window allowing the passage of electrons and composed for example of beryllium or other inorganic or organic material of light atomic weight.
  • the passage window particularly when employing canula: or probes, is preferably constructed in pointed form, or as partofapoinhifattheenditisdesiredtc obtain notanexit'oftheelectrons onallsides, but a directed emission of the electron
  • This apparatus is facilig tated by providing in addition to the passage window'a special window for the discharge tube.
  • the passage tube maythen be removed without diinculty from the discharge tube, 1. e., without affecting the discharge tube.
  • the passage will then also be sealed in itself, so that under certain circumstances the same may also be evacuated, or filled with a gas of desired nature.
  • the electrons produced in the tube pass throughthe'tip of the canula into the part under treatment.
  • the useful effect of the electronic radiation is a very considerable one.
  • considerable energy may be passed through the passage, and the time of radiation may be very short (fractions of a. second). This is a great ad- 30.
  • the introduction of the probe or canula into the human body is accompanied by a great deal of unpleasantness and pain, which in accordance with the invention is reduced to a minimum.
