    N° 1158 A.D. 1901 Date of Application, 17th Jan., 1901—Accepted, 23rd Feb., 1901 COMPLETE SPECIFICATION. Improvements in Instruments for Administering Medicaments or the like.” I3 Dr. Alexander Levy of Hagenau, Alsace in the Empire of Germany, Surgeon, 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; — 5 This invention relates to a means or appliance for conveying and introducing medicaments, such for instance as causticising solutions, into peGs of the human body which are difficult of access, massage being simultaneously applied. The parts more particularly in question are the masculine urethra, the uterus, the nasal cavity and the like. The essential feature *of the invention consists D) in the head of the instrument being traversed for a certain length by numerous capillary passages which are intended to receive medicaments and to easily discharge same again when a slight pressure is applied. Various forms of construction of the instrument are shown in the accom¬ panying drawings, in which 1 5 Figure 1 is an elevation of an instrument intended for the masculine urethra; Figure 2 a longitudinal section of same; Figure 3 an elevation of an instrument destined for the uterus; Figure 4 a longitudinal section of same; Figure 5 an elevation of an instrument suitable for the nasal cavity; Figure 6 a longitudinal section of same; Figure 7 a section on an enlarged scale on the line x y of 20 Figures 2 and 4; Figure 8 a section on the line v w of Figure 6; and Figures 9 and 10 a modified form, in elevation and section respectively, of an instrument for massaging from the inside to the outside. In general the medicament carrier according to the present invention has the shape of a catheter of ordinary length and calibre. The instrument a is made 25 of soft rubber. Inside the same there is a central longitudinal bore h serving essentially for guiding the instrument, whilst a silver wire of suitable thickness is employed as mandrel for tlie guidance. The head of the instrument, according to requirements, is provided up to a certain length with fine intercommunicating and externally opening capillary 30 tubes c, which extend, in' the catheter intended for the masculine urethra (Figures 1 and 2) for instance, to the length of 3 to 4 centimetres, in the catheter for the uterus (Figures 3 and 4) to from 10 to 12 centimetres, and so forth. The bore b is continued to the head of the instrument and connected with the capillary tubes c so that the easy insertion of the medicinal solution and the discharge of the same is facilitated as the air contained in the capillary tubes can escape from the perforation b. No openings exist at the point d of the catheter, so that thus the actual point itself is closed and rounded as is usual in like instruments. In the catheter for the uterus (Figures 3 and 4) a knob or stud is provided at 40 the side as is usual in the uterus probes at present in use, for the purpose of measuring how far the catheter has penetrated into the recess of the uterus. In catheters for the nasal cavity (Figures 5 and 6) the head is formed into a broad flattened (leaf shaped) heart shaped end piece f which in similar manner is traversed by outwardly opening capillary passages. For other purposes a suitable form must of course be given to the catheter. [Price Sdf] 45
