To all whom it may concern: l I
Be it lrnown that I, HUGO PioAno, a citizen of Germany, residing at Berlin, Germany, have invented certain new arid use- 5 ful Improvements in Irradiating Chambers;
5 for Therapeutical Uses (for. which I'have filed an application in Germany July 13, 1921), of which the following is a specifica-' tion. 4 My invention has reference to an irradiationand ionizationsc'hamber for purposes of light therapeutics, and it is intended to improve the general construction of de. vices of this kind so. as .to intensify the action of light or of cther radiantagents to be curatively applied to the objects housed in suchchambers. It has already been suggested to utilize light reflecting mirrors or metal walls for the coating of sweating boxes heated by electric light, and according to other suggestions sources of light employed for radio-therapeutic purposes have been housed in boxes likewise coated with light reflecting metal plates similar to the construction of vehicle head lights and reflec-- tors.
: My invention, besides presenting other iins portant novel features, is distinguished from 'the previous dcvices referred to'bythe fact 80 that it provides an irradiation chamber .closed on al l sides, and all the enclosures of which, that is to say, not only the side walls but also the cover, and, whenever desired,
the-bottom likewise are constructed so as to resent bright strongly. reflecting metal suraces. By this means the living beings to be irradiated in this chamber, besides being directly irradiated, will be submitted-chiefly or to a large extent to an indirect irradia- 40 tion by reflection with the utilization of the "light otherwise lost .by dispersion. An irradiation chamber according to vthis invention, therefore, presents theadvantage that owing to theutilization of diffuse light the electric energy supplied tothe. lamps is utilized far more efiicientl y, their therapeutic efficiency being likewise enhanced by i1 1-. creasing their actinic eflicacy; In the irrad1-- ation chamber a plurality of persons may be 59 treated at a time, and the possibility is afforded to the persons within the chamber to move about, without interrupting the opera-,
" tiveness of the all-sided irradiationn "In view of the utilization of reflected 1i ht a shorter period of time sufliees for pro ucing a cerber has oval or elliptical cross section.
- tam irradiating action than t was possible to obtain with the devices heretofore in use.
The invention is adapted for all possible irradiating purposes, this for instance for irradiation .by mercury Jvapor lamps, "for treatment by means of-the aureol' lamp, the spectrosol lamp and similar equivalent means, without any dangerof producing burning phenomena. The irradiating cham- For the purpose of coating the irradiating chamber in accordance with this invention in order to convert its inner walls into a pair of oppositely arranged parabolic reflectors merging into each bther, I may make use of specially treated strongly reflecting -very bright metallic surfaces, of aluminium for example. Inasmuch .as the different metals in view of their different atomic weights possess different absorbing capacities for rays of difiere t wave lengths the said metal surfaces .may ef treated with other metals or metal compounds in such a manner as to absorb rays of-a certain wave length, and to cause only-therapeutically valu le rays of light to be utilized. The application of such metals,-for example of tin, bismuth and the.
like, l1 pon the metallic wall, thus for examof example in'vertical; longitudinal section in-Figure 1. b Figure 2 is a transverse section, and Figure 3 is a planview. a
In the modification shown in the drawtical, plan; and the vertical longitudinal section is likewise elliptical with the excep- I tion of the "bottom surface which is plane. The transverse sectional form issubstantially horse-shoe or U-shaped. The walls oi are covered with highly brilliant metallic surfaces 6. The walls are ,interru ted at the point where the door d is inserte which is likewise covered with highly brilliant sur- .ing the chamber is constructed on an ellipfaces. The door at is preferably provided with a loop hole to be closed by a slide, likewise with highly brilliant metallic surfaces.
For theadmission of fresh air passages f are provided near the bottom which are preferably. also covered or shielded with metal plates is, so that the fresh air enters the chamber between these plates and the wall itself. The consumed air is, sucked off from the top of the chamber by a ventilator or fan g. The air outlets are also preferably shielded or covered by a bright metallic plate m, as shown in the drawing.
The sources of light care mounted upon special supporting means 0 which project through the walls a and may be supported on standards 41, which may be so arranged and constructed as to allowof an adjustment of the sources of light for close and distant irradiation. The said sources of light a may consist of quartz lamps or of any other suitable light emitting means.
The invention is not restricted to the par ticular configuration of the chamber herein shown and described as one of the many forms of embodiment of which the invention is susceptible. These features may be "changed to suit existing conditions and 1. Irradiating chamber for therapeutic purposes comprising in combination, a shell having the form of an ellipsoid of rotation cut by a plane representing the floor, means I in the two foci of the ellipsoid for emitting therapeutically useful rays, and metallic surfaces of high reflecting capacity on the inner side of said shell. 46
2. Irradiating chamber for therapeutic I purposes. comprising in combination, a shell having the form of an ellipsoid of rotation out by a plane representing the floor, means in the two foci of the ellipsoid for emitting i0 therapeutically useful raysand aluminium lining of high reflecting capacity on the inner side of said shell. 7 l
3. Irradiating chamber for therapeutic purposes comprising in combination, a shell having the form of an ellipsoid of rotation cut by a plane representing the floor, means in the two foci of the ellipsoid for emitting therapeutically useful rays, and metallic surfaces of high reflecting capacity on the inner side of said shell, a coating on said surfaces having a different absorbing capacity' for such rays.
4. Irradiating chamber for therapeutic purposes comprising in combination, a shell as having the form of an. ellipsoid of rotation cut by a plane representing the floor, means in thetwo foci of the ellipsoid for emitting therapeutically useful rays and aluminium lining of high reflecting capacity on the inner side of said shell, a coating on said surfaces having a different absorbing capacity for such rays.
5. Irradiating chamber for therapeutic purposes comprising in combination, a shell having the form of an ellipsoid of rotation cut by a plane representing the floor, ventilating means arranged in openings of said shell, means in the two foci of the ellipsoid for emitting therapeutically useful rays," 0 and metallic surfaces of high reflecting capacity on the inner sides of said shell and said openings.
In testimony whereof I affix my signature.
