    N° 15,231 A. D. 181)6 Date of Application, 9th July, 1896—Accepted, 15th Aug., 1896 COMPLETE SPECIFICATION. Metal-sound-pipe for Medical Purposes. I, Franz Kuhn of Giessen, in the Empire of Germany, Physician, do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement:— The metal-tube which is the object of the present invention and which is represented in the accompanying drawing, is distinguished from other instruments, used hitherto for similar purposes, by the following facts : — (1.) The present sound-pipe owing to its peculiar principle, meets all require¬ ments for which, till now, special instruments have been employed made of 111 different substances and on entirely different principles, whereas this one is more durable, simpler and more modern. It takes the place of any kind of bougie and may be substituted for those pipes which are made of silk tissue impregnated with resin, or of hard or soft gum and such like. (2.) By the principle of this invention, the use of such instruments, will become 1*> more general and may be more widely applied, as new questions relating to medicine can be thereby solved and new fields can be opened to scientific investigation. Compared with the pipe, at present employed in medicine for various purposes, the advantages of my metallic tube are :— (1.) It possesses very great flexibility, making it preferable to any other, even to 20 those of india-rubber ; at the same time its flexibility may be changed at the desired moment, even after introduction into the body, by the help of apparatuses introduced into the sound-pipe. Thus, for the first time, the safety conferred by the use of the softest pipe is combined with the precision of the most rigid instruments and this double 25 advantage is obtained in the same pipe at any moment, during or after intro¬ duction. (2.) The new pipe affords an adjustable mobility hitherto unobtainable as well as an optional impressionability in curves and in the direction given to the instrument at any part of its progress, this also being accomplished by mechanical 30 means. (3.) The metallic-tube or sound-pipe does not break and does not bend at an acute angle as do all instruments used for similar purposes; its interior is always open and accessible. Moreover it lasts a long time. (4.) The interior walls of the hollow tube are smooth and slippery because they 35 are of metal. The friction being thus rendered very slight, even in case of curvature, all kinds of instruments may be introduced, for the most various purposes, into the inside of the sound-pipe and for a considerable extent, which is not the case with the flexible pipe now in use. In case of necessity, instruments may, without danger, be introduced beyond the pipe. 40 (5.) The spiral sound-pipe permits the transmission, from one of its extremities to the other, of different forces without changing its shape and position and independently of bends and flexions, which is an advantage offered by no other sound-pipe. (6.) The tube is capable of rotation on its own axis, whatever may be its position 45 and its shape, a great advantage hitherto unobtainable, especially in operating upon delicate organs and in many other cases. This rotation can be effected at great distances, thus enabling internal organs, far removed, to be reached, such, ior instance, as the pylorus and the small intestines. [Price 8if.]
