SPECIFICATION forming part of Letters Patent No. 769,581, dated September 6, 1904. Application filed February 20, 1904. Serial No. 194,599. (No model.)
To (LU. 1117110111, it 'ntrr/y (Oil (Writ:
Be it known that I, WILL Fom) ARNOLD, of the United States Navy, have invented certain new and useful Improvements in Phototherapeutic Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.
The object of this invention is to provide improved means for securing the safe and eflicient application of light to the treatment of infectious affections of the skin and deeper tissues and organs and also of bones, so that, if necessary, the concentration of the lightrays will tend to be below the superficies.
A further object to avoid calorific injury to the tissues by the heat of the light-rays; and a further object is to additionally protect the skin by means which will immediately indicate the presence of too great a degree of heat that is, such as would tend to injure tissues which may be alrcad y inflamed or irritated.
In the accompanying drawings, Figure 1 is a view in perspective, showing in conventional form means for carrying out my invention. Fig. 2 is a view of the reflector. Fig. 3 shows the concentratordetached. Fig. I is a transverse sectional view of a concentrator whose truncation is beyond the point of principal focus. Fig. 5 shows means for removing and neutralizing the heat-rays.
In carrying out my invention I seek to concentrate the light-rays asevolved byan electricarc lamp or else by the Nernst lamp upon the affected part or parts, the heat-rays being removed by currents of air induced either by a blower or by a suction-punip, or both removed and neutralized by utilizing the refrigerating principle of the expansion of compressed gas or gases, which latter may also be availed of for their combining proclivities under the influence of strong light to form useful disinfectants and parasiticides and for the formation of organic peroxids and cognate chemical substances which are powerful disinfectants, deodorants, and bleaching agents. I preferably employ either a small arc-light or a Nernst lamp, (which latter I have found generally most desirable for my purpose,) whose are crater or glower, as the case may be, is at the principal focus. The light'rays and the ultra-violet and other rays generated by the lamp are concentrated at a point at varying depths below the surface by the use of properlytruncated concentrators in the form of hollow paraboloids with silvercd inner surfaces, ordinarily called parabolic reflectors, and cut perpendicular to their axes near to the principal focus, but beyond it toward the open end, or it may be exactly at its focus, so that when cut off at the focus it will reflect every ray that it receives at its focus upon the skin or tend to concentrate them deeper on the affected part if truncated higher up. If the truncation be made variously but mostly within or above the point of focus, concentration will be directed toward a point variously situated in different cases below the superficies, as already stated. The advantage of this in operating upon tu: berculosis of bone, &c., that is frequently deeply seated. is apparent. The light'rays are reflected from the lamp by a truncated or suitably-slotted paraboloid, of the same characteristics as the concentrator, the two being in axial line with and facing or looking toward each other.
The third point in my invention resides in the protection of the part to be operated upon by the use of sheets of gelatin of proper thinness and transparency supplemented in appropriate cases with oil, &c., for excluding from the skin atmospheric air and so constituted that they will immediately melt when the temperature reaches 100 Fahrenheit, affording reliable indication as to the presence of even innocent but undesirable quantities of heat, thereby avoiding calorific injury to the tissues.
To the end that my invention may be clearly understood I have indicated in Fig. 1 a phototherapeutic apparatus by which it may be carried out.
1 designates a Ncrnst lamp suitably mounted on a stand 2 and to which is secured a parabolic reflector 3. The reflector maybe of any desired size and is preferably equipped with a rim &, designed to be engaged by screws 5,
by which the shade or globe is ordinarily held. This reflector is shown as truncated, the truncation being perpendicular to its axis at its principal focus. Such truncation is not, however, essential to all reflectors, as it depends upon the accessibility of the source of light. A second Daraboloid, serving the oflice of a concentrator 6, which must always be truncated, is secured in direct axial line with the reflector 3, so that by facing the latter it will concentrate the parallel rays at its principal focus. The whole circle, or bottom of the concentrator, will be illuminated both by the rays (which from the appreciable size of the light source lack exact parallelism) from the refiector 3 and by the divergent rays proceeding directly from the lamp itselfthat is to say, those which have not undergone reflection. The concentrator may be held in direct line with the reflector by a skeleton frame 7 or other suitable means. I have also inclicated at 8, Fig. l,'a power-actuated fan for forcing a stream of air so as to remove the undesirable heat from the light-rays on the part being operated upon. This is accomplished by directing a current of air into the concentrator; but in lieu of a fan a blower driven by electricity or by water or by other source of power may be employed. In fact, it is preferable. WVith'low-powered lamps it will be sufficient to exhaust continuously the air from the concentrator by using some convenient form of water-pump, such as are daily employed for producing vacua, &c. or, again, compressed gases may be directed into the concentrator or upon the part or parts undergoing treatment, as stated above, as shown in Fig. 5, wherein 12 indicates a short tubular member inserted in the concentrator into which the mixed gases are supplied from a storage-tank, such gases passing off into a cup of mercury, (indicated at 13.) The film of gelatin-is shown as resting upon the tubular member 12 and is marked lt in this figure. The lower edge of the tubular member contacting with the limb of the person being operated upon, all gases will pass from the source of supply outwardly into the cup of mercury.
Across the focal end of the concentrator that is, between the latter and the member to be treatedis placed a film of gelatin 9, (see Figs. 1 and 1,) which should be usually at the point of greatest heat and is capable of being melted at a temperature of about 100 Fah-' renheit. This film, while being of sufficient thinness and transparency to permit of the passage of the light-rays, affords valuable indication as to the presence of any injurious degree of heat. For the further purpose of excluding atmospheric air, of avoiding undesirable pigmentation effects upon the human skin, and for securing certain chemical results mentioned herein I may use oils and allied substances in or on the bottom of the concentrator, inclosed or not, as may seem desirable. In lieu of the film of gelatin a capsule 10 (indicated by dotted lines, Fig. 1) may be employed.
In Fig. 4 I have indicated a concentrator wherein the truncation is made beyond the point of focus, so that subcutaneous concentration of light-rays and of other rays capable of reflection may be effected. The truncation of the concentrator is shown in Fig. 3 as being exactly at the principal focus.
The employment of a lamp for the purposes of my invention will not interfere with its ordinary use. After the usual ground or frosted glass shade or globe with which lamps of the power under consideration are always provided, but which are not used by me in my phototherapeutic apparatus, shall have been restored no inconvenience will resultin using the lamp as customarily employed. It will also be noted that since the apparatus involves but few parts it may be readily transported, being of but little weight.
For operating the motor any metallic water-motor readily attachable to a faucet may be used or any other convenient form of power@. g., spring-motors, &c.or in lieu of a motor a cylinder of compressed gas (see Fig. 5) or a tube of ethyl chlorid may be employed as the agency for neutralizing the heat-rays.
I claim as my invention- 1. A phototherapeutic apparatus comprising a source of light, a reflector therefor, a concentrator for the light-rays in axial line with and facing such reflector, and means for removing the heat-rays from the concentrated light-rays in proximity to the point of utilization.
2. A phototherapeutic apparatus comprising a source of light, a reflector therefor, a concentrator for the light-rays in axial line with and facing such reflector, such concentrator being in the form of a truncated parabolic reflector cut perpendicularly to its axis at or above the point of principal focus, and means for removing the heat-rays from the concentrated light-rays.
3. In a phototherapeutic apparatus, alightconcentrator in the form of a truncated paraboloid cut perpendicularly to its axis at or above the point of principal focus.
4. In a phototherapeutic apparatus, a lightconcentrator and a transparent gelatinous substance intermediate the source of light and the object under treatment.
5. A phototherapeutic apparatus comprising a source of light, a reflector therefor, a concentrator for the light-rays in axial line with and facing such reflector, and a transparent gelatinous body in or near such concentrator.
6.
