Definitions

  • appliances for the treatment of the larynx with ultra-violet rays in which a, curved quartz glass rod, or a light conducting member, consisting .of several arcuately curved closed quartz members, serve for conducting into the larynx the rays of a source of light held outside the mouth.
  • Suchappliances have, however, the prohibitive drawback that the ultra-violet rays are largely absorbed in the long path which they must traverse through the quartz conductor, and it is not possible to conduct the rays to all sides of the larynx below the epiglottis.
  • the present invention relates to an appliance for the treatment of the larynx with the ultraviolet rays emitted by a mercury-vapour lamp in which the discharge space of the vapour lamp is provided within the end portion of a hollow body" which is made of material permeable to ultraviolet rays, and which is so dimensioned and curved that it can be introduced simply into the larynx in the manner of other instruments employed in the examination and treatment of the larynx.
  • Fig. 2 is a longitudinal section of the same.
  • a tube l2 which is likewise introduced through a hole in the plug 9, which traverses the partitions 8 and I0, and which projects into the interior of the hollow body 2.
  • the tubes II and I2 can be madeof metal and are provided at their ends projecting from the plug 9 with connecting pieces I3 to which flexible tubes can be attached.
  • the tube 12 is connected to a water l
  • the current leads 5 are con- 4 nected to a current supply of suitably high voltage, and the appliance is so held by the handle 14 that the sharply curved portion 4 of the U- shaped tube 3 of the mercury-vapour lamp is directed downwards.
  • the appliance is then so turned that the sharply curved portion of the U-shaped tube 3 is directed upwards, so that the mercury flows away from the sharply curved end portion into the two side limbs of the U-shaped tube.
  • a gap is produced between the two columns of mercury, which gap can be so dimensioned by the correct determination of the quantity of mercury inserted in the U-tube that an arc-discharge is started between these two columns.
  • the inherent pressure of the mercury vapour thus generated between the two.
  • mercury electrodes in the sharply curved end portion of the U-tube is sufficient to prevent the two columns of mercury from coalescing in the said end portion when the appliance is again turned with its pointed end downwards.
  • the appliance can thus be rotated, turned, and tilted in any direction without causing the mercury electrodes to approach each other, and it is thus possible to maintain the arc in any position of the appliance, a feature necessary to enable the appliance to be introduced into the larynx.
  • the sharply curved end portion 4 of the U-tube 3 can be made of slightly narrower bore than the two side limbs of this tube, and that either throughout this portion or at certain points, and the constriction may even be such as to be of a capillary order, so that capillary resistance aids in preventing the mercury columns from coalescing.
  • the appliance In order in this case to bring the mercury columns together and then to separate them at the start, as is necessary for the purpose of ignition, the appliance must be shaken or jarred in the manner usual with clinical thermometers to-bring down the mercury column.
  • the hollow body 2 It is advisable as a rule to restrict emission to the extreme outer end of the mercury-vapour lamp, and to this end it is possible to provide the hollow body 2 with an impermeable protective sleeve I5 or with an impermeable coating, leaving only the extreme tip 4 of the lamp free to emit rays. It would also be possible to make the greater part of the hollow body 2 of material impervious to ultra-violet rays and to fit a separate tip of pervious material atthe extreme end only.
  • the two electrodes can also be held apart by the insertion in the sharply bent portion of this tube of a certain quantity of gas, preferably of a rare gas which at the same time serves to allow of or even to facilitate the starting of the mercury arc. 7
