![f-' ■ ^ Specification, A.D. 1872.—N*’2251. . - .. i --—_____ ; Mattson's Improved Apparatus for A dmln istering Injections. according to the size of the nostril; sixth/ a naso-pharyngical tube used in connection with an elastic bulb syringe for directing a stream of water through both nostrils at the same instant; seventh, a box with a peculiarly constructed tray, in which the apparatus is kept compactly in 5 place without shaking? or rattling. Deschiption of the Drawing. ^ Kgure 1 shows the aforesaid bulb and flexible tube; Digure 2 shows ^ one of the rigid inlet or supply tubes; Digure 3 shows my improved If vaginal irrigator ; Figure 4 shows my improved nasal irrigator or plug ; 10 Figures 5 and 6 are two views of the aforesaid naso-pharyngical iiiigator \ Figure 7 is a perspective view of the box in which my appa¬ ratus is packed. Dike letters indicate the same parts throughout the Drawing. The bulb or bottle a is egg shaped, as shown, and is vulcanized I 15 without an aperture, and consequently without a neck. A-small \ aperture is drilled at either end, and into this aperture a screw coupling b I with a round head, and made of metal or other suitable hard material, I is inserted. To this screw coupling is connected the upper section c of ] the inlet or supply tube. Syringe bottles vulcanized with necks, how- I 20 ever they may be fastened, are liable sooner or later to leak, but no ^ leakage will occur with the device herein described. I The ordinary rigid inlet tubes of syringes are not constructed in sections, so as to be shortened at will for the purpose of being packed in a smaller box than would be otherwise possible. But my inlet tube 25 consists of three sections. The upper section c is connected with the bulb, as above described, and has a branch coupling y* for the elastic outlet or'discharge tube The next section c? of the said inlet tube contains the inlet valve. The third or lower section e is of sufficient length to draw water from any ordinary household vessel. The said 30 sections are formed with screws at their ends for connecting them. But in the lower section ea slip joint is sometimes used instead of a screw. This section is intended to be detached for the purpose of economical packing, as already described, and its separation is effected without dis¬ turbing the aforesaid valve. The sections c, d, e, may be constructed 35 so that the two lower ones with the valve in place may be removed from the syringe for packing, or all three of the sections, if desirable, may be detached from the bottle for the same purpose.](https://iiif.wellcomecollection.org/image/b30750842_0007.jp2/full/800%2C/0/default.jpg)
