v THERAPEUTIC LAMP.

Application filed November 29, 1924. Serial No. 752,998.

My present invention relates to a source of ultra-violet light for. therapeutic uses and particularly to such a source adaptable for 1 plication is shown in vertical section the source of ultra-violet light of my invention as applied to an arm for example showing means for applying pressure to the part to be treated, means for varying exposure area,

and means for cooling the light source.

In the drawing the jacketed lamp casing l is held to the arm 2 by means of the straps 3, the Window portion 5 of the lamp being heldby said stra s 3 to that portion of the arm to be treated? Said window portion 5 com rises an iris diaphragm which is collapsible and openable for the purpose of var ing the exposure area, the device being hel by said straps 33 or equivalent means to the part'to be treated in such a manner that the boundary of the opening 6 of said iris 5 is held tightly against the tissue surrounding the part to be treated. The insulated members 88 pass through the jacket wall of the container '1 and carry therethrough the terminal leads 9-9 which end' in suitable electrode terminals 10-1O properly spaced from'eac-h other within said casing 11. The inlet pipe 12 and the outlet pipe 13 serve to admit cooling material such as water to and from the jacket of the casing 1. The pipe 15 passing entirely through the casing 1 and opening into the interior thereof serves to admit hydrogen into the interior of said casing 1 and against the tissue to be treated for the purpose of dehematizing. The gauge 16 on pipe 15 serves to indicate the pressure applied to the tissue to be treated.

In the use and operation of the device of my invention the lamp casing 1 is attached to the part to be treated as by means of said straps 33 under the proper tension and pressure and a cooling liquid is started circuof said

pipes

12 and 13. Pressure is then applied to the art to be treated by admitting hydrogen or example into the interior of the casing 1. which at the opening 6 is lating through the jacket thereof by means,

bounded by the tissue to be treated. The lamp casing 1 being held against the tissue to be treated by said straps 33 or equivalent means it is ossible to obtain a practical holding of the ydrogen under pressure in the lamp casing against the part to be treated. Current is then applied to the

leads

9, 9 of the

electrode

10, 10 from a suitable source for the producing of an arc for the production of ultra-violet light, the hydrogen being a transmitter of ultra-violet light and also serving as means for insulating the part to be treated from the heat of the are.

In the apparatus and method of my invention I employ the atmosphere, hydrogen for example, as a suitable medium in which to generate the'ultra-violet light producing are, as means for applying pressure to the part to be treated, and as a cooling medium. In some cases I use the hydrogen for cooling without'employing the medium such as water in the casing jacket. Flow of hydro gen when desired to secure the desired cooling effect I produce by permitting the hydrogen to escape around the edges of the opening 5 or when desired or required I provide another pipe for its exit.

I claim:

1. A therapeutic apparatus including a holder member having an aperture for application to the part to be treated, a source of ultra-violet light within said holder and means for applying a gas under pressure to the part to he treated at the area confined by said opening.

2. A therapeutic apparatus including a holder member having an aperture for application to the part to be treated, a source of ultra-violet light within said holder and means for applying a gas under pressure to the part to be treated at the area confined by said opening, and means for cooling said casing. 1

3. In a therapeutic appliance a jacketed casing, inlet and outlet paths for distributing cooling fluid through the jacket of said casing, a source of ultra-violet lightin said casing, an opening in said casing, and a pipe to the interior of said casing.

4. In' a therapeutic appliance a jacketed casing, inlet and outlet paths for distributing cooling fluid through the jacket of said casing, a source of ultra-violet light in said casing, an opening in said casing, an iris dia hragm across said opening, and a pipe to t 6 interior of said casing.

5. A therapeutic apparatus including a holder member having an aperture for ap- 5 plication to the part to be treated, a source of ultra-violet light Within said holder and means for applying a gas under pressure to the part to be treated at the area confined by said 0 ening, and adjustable means for vagying t e size of said opening. 10 igned at Hoboken in the county of Hudson and State of New Jersey this 28th day of November A. D. 1924.
