WILLIAM MEYER, OF CHICAGO, ILLINOIS.
To all whom it may concern Be it known that I, WILLIAM MEYER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Therapeutic Apparatus, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to therapeutic apparatus and more particularly to a table for taking X-ray photographs of the body and for administering electrical treatment.
In taking X-ray photographs or shadowgraphs, as they are often termed, it is necessary to hold the sensitized plate in a fixed position so that the proper degree of exposure will be obtained. Where the plate is attached to the patient, movement of the patient will take the plate out of the proper position and will prevent proper degree of exposure and proper location of the exposure. I have found that the only dependable method of making exposures is to have the patient rest upon a support which also supports the photographic plate. Thus, if the patient moves slightly, the adjustment of the plate with respect to the 'X-ray tube is not destroyed, and the chances of movement are much lessened.
The object of the present invention is to provide a suitable support for holding'a photographic or other sensitized plate in suitable position for making any desired exposure through a part of the anatomy. According to my invention, I provide a support in the form of a table which is provided with an adjustable portion for holding a plate in a number of positions to provide the maximum utility for X-ray purposes.
As the operator is frequently called upon to give the patient electrical treatment known in the art as auto-condensation, I provide means whereby such treatment may be afforded while the patient is resting upon the table.
In the accompanying drawings which form a part of the present specification, I
have illustrated one embodiment of'my ina neat and finished appearance.
Specification of Letters Patent. t t t 25, 191% Application filed January 17, 1916? Serial No. 72381.
Fig. 4 is an elevation of the table showing the insulating pad which is employed for certain treatments and Fig. 5 illustrates the manner of adjusting the table. g
The device shown in the drawingscomprisesthe four corner posts or legs, 1, 2, 3 and 4. These posts are secured together by suitable side pieces 5 and suitable end pieces 6, to form a rectangular frame. The side pieces 5 have a brace 7 between them, extending the full width of the side pieces. A brace 8 is secured to the bottom of the brace 7, and to the left end piece 6. The brace 8 is employed in connection with the adjustment of the plate holding mechanism, aswill be described later. The side 5 and the end 6 may be further braced in any preferred manner, such as by the corner braces 9 and'Q shown in Fig. 1.
A suitable top 10 extends over the lower part of the frame and in the form shown in the drawings, the same is covered with fabric, bound by the metal strap 11 to present It is to be understood that this may be finished in natural wood as is the rest of the table. A foot board 12 is hinged to the top portion 10 andv rant 13, which is arranged to engage a pin 14 projecting from the leg 2.
Adjacent the top portion 10, I provide a thin top portion 15 which is covered with a sheet of metal, preferably aluminum or a similar conducting substance, which will not materially retard the passage of the X-rays. A slot or opening 16.beneath the portion 15 is provided to receive the plate holder 17 Suitable guides, not shown, are provided beneath the slot 16 for supporting the plate holder when it is inserted in the slot 16. A stop 18 which may be secured to either side of the table prevents the plate holder 17 from being pushed too far through the slot 16. A crossbar 19 which supports the top portion 15 is secured above the brace 7 to the sides 5, 5. An open frame member 20 which is secured to a similar crossbar 21 is I connected by means of the hinges 22 to the crossbar 19. A rod 23 is pivoted upon a crossbar 24. The lower end of the rod 23 passes through a bolt 25, which is provided with a thumb nut 26 for gripping the rod 23 in any desired position. The. crossbar 24 extends across the open frame 20 and carries I a similar adjusting bolt 27 for gripping a rod 28 pivoted at its other end to the hinged top portion 29. The top 29 is hinged to the frame 20 at one side so that the same may be raised. as shown in Figs. 1 and 5. The top portion 29 comprises a frame 30 which is slotted, as shown at 31, for receiving plate holder 17, and a top portion 32 which is formed of a light metal such as aluminumor other conducting material which will not 1nterfere materially with the passage of X-ray the'rethrough. A cross bar 33 bears the upper end of the rod 28 and provides for holding the top portion 29 in the raised-position. The metallic top portion 15 and the -metallic portion 32 are connected together by a flexiblecable 34, as shown in Figs. 4 and 5,
so that although they are mechanically adjustable, with respect to each other, they are at all times in electrical connection. A
- suitable terminal 35 is provided for the at- I as justable portion slightly so as to remove the inconvenience. When shadowgraphs-of the head or shoulders and the thorax are to be made, the patient is placed upon the table in the general position shown in Fig. 4, be
ing moved up or down in order to secure the proper exposure. The plate holder 17 is then inserted in the top portion 32 and the entire table which is provided with the antifriction rollers 37 is then pushed under the X-ray tube and the exposure made. If it is desired to make a shadowgraph of the groin or of the lower extremities, the plate holder- 17 is inserted in the slot 16.
The X-ray tube 38 may be adjusted to the proper height before the .patient is placed upon the table. This facilitates the work and makes the same less burdensome to th operator and to the patient.
Where a shadowgraph of the abdomen. is to be taken the top portion 29 is raised, as shown in Fig. 5, and the patient rests the abdomen against the top thereof, The plate holder 17 is inserted in the ways 31 so as to be held. in the proper position. The X- ray tube 38 is then placed backof the patient and the rays directed through the body as may be required. 1
Where the patient is to be given treatment with high frequency current, the insulating pad 36 which is preferably made up of a number of layers of insulating material or of a soft pad of considerable thickness, is placed over the table .and the patient is placed upon the pad; The patient and the metallic plate with the insulation interposed,
thus form a condenser. The patient grasps one electrode which is preferably in the shape of a large conducting baror rod to increase the surface of contact, and the pa: tient is then subjectedto a high tension highfrequency discharge.
-While I have described my invention with reference to the details of a particular embodiment, it is to be understood that I donot intend thereby to limit my invention to the proportions or dimensions or precise construction shown and described,-but intend that all such modifications as will suggest themselves to one skilled in the art, be considered as coming Within the spirit and scope of my invention.
