Definitions

  • This invention relates to a vacuum tube, similar to the well-known X-ray tube and adapted for use in the same general manner for the treatment of certain skin affections, and for other similar purposes which require the direct application of the window end of the tube against the parts.
  • An object of the invention is to provide a tube of this type having the contact surface of its window end made of such contour that when being applied to a surface to be treated it may be moved from one point of application "to another adjacent point and then to another, and so on, and thus be made to cover substantially the entire expanse of surface without necessity for any lapping of treatments and with a greater degree of certainty upon the part of the operator that the entire affected surface has been covered than has been pos sible with the usual circular Window end heretofore employed. 7 V
  • a further object is to so design the window end portion of the tube that substantially all portions of the contact surface shall be effective for imparting proper treatment to the affected parts.
  • Figure 1 is a perspective .viewofa vacuum tube constructed in accordance with this invention
  • Figure 2 is a bottom plan view of the window end seen in Figure 1, and illustrating in dotted lines the manner in which the tube would be moved from one point to another for properly treating the full expanse of an affected surface.
  • the reference character L indicates the main or body portionv of the tube, having the opposite extensions G and H. for carrying the electrodes for the attachmentcf conductors.
  • A-suitable handle 1 extends laterally from the vertical extension part 2 at the top of he body 'L, and by means of this handle the entire device may be readily manipulated in use.
  • This handle is preferably attached to the extension 2 below the top end of sald extension as ll ⁇ has been found that greater strength and convenience can be secured by this arrangement.
  • L has the usual globular form
  • the lower or window portion as 4 shall be of rectangular form
  • the bottom or contact surface as 5 shall be ofsubstantially square contour
  • the Walls of the window portion shall be tapered gradually upwardly and outwardly in all directions-to merge with the upper portion 8.
  • a vacuum lube ol' the type indicated having a window portion ui'lii jited to be moved about on eliliet'ed surface for treating said surfnee the eonteel' surtuee of suid Window portion living of subutiu'itiully nquni'e (-oiitour whereby to avoid noi'essity for overlapping treatment of any portion oi? the :rllliel'ed surface while yet enabling treatment of the entire afiiieted surface as and in the manner set forth.
  • A. vacuum tube of the type .iudiouled comprising: the HEBHHl relatively large globulur body part and a downnuu'iflly extending reliitivel smallv window end portion, said window end portion being of rectangular form.
  • the contact surface thereol" being of sulilstiintinlly square ronl'our, and the side walls thereof tapering gradually upwurdli and outwuri'lly to merge inlo the globular portion of the body, for the purpose set forth.
