M. NEGRI ODONTALGIO DEVICE 2 sheds-sheet 1 Filed April-1 9, 1951 I." IJONfo M. NEGRl ODONTALGIC DEVICE June 16, 1953 I 2 Sheets-$11962 Filed April 9. 1951 Patented June 16, l9 3 UNITED STATES "rer- 3 Claims. 1 The present invention relates to a device for bringing in contact with the internal surface of theexte'rnal auditory meatus an analgesic fluid for acting on the innervation of the trigeminal' nerve.

According to the invention a vial containing the analgesic fluid is inserted in a protecting containe'i'having a substantially frusto-cohical shape and from the and corresponding to the minor basis of the "fru's t'o-cbiie there projectsa'n absorbent eie'inemus'eutb spread the fluid inside the auditory meatus.

2 tion, "with a needle-shaped projection It, and arcund tni's latte r'with a cylindrical flange I2 which surrounds the vial containing the analforce, owing to the action of the inclined plane of the thread.

The cap may be extended by a handle to facilitate the screwing.

Two preferred forms of embodiment of this invention are shown in the enclosed drawings,

wherein:

Fig. 1 shows an elevational view of the device with the cap on;

Fig. 2 shows a central vertical cross-section of Fig. 1;

Fig. 3 shows a view of a different form of embodiment of the container and,

Fig. 4 shows thercentral vertical cross-section of the container of Fig. 3.

With reference to the drawing:

The form of embodiment shown in Figs. 1 and 2 comprises a frusto-conical rigid container I, reinforced by ribs 2. The container has at one end a cylindrical portion 5 with threads 6, on which the cap I may be screwed.

Inside the container i, absorbent material 8 is placed, formed for instance bywadding, a part of which is wrapped in a covering 4 made of a sheet of gauze, and projects from the end 3 of the container. A vial 9, containing the analgesic fluid, and provided with a rod I6 is arranged in the container and rests on the wadding, while the rod l6 penetrates into the wadding 8.

ge'si'c. When the cap I is screwed on the cylindrical part of the container i, the needle H causes the breaking of the vial '9, while the part I 2 which, owing to the descent of the cap l, surrounds the vial 9, prevents the dissipation of the-fluid outside the container.

The wadding 8 then absorbs the analgesic fluid which through the projecting part I"? comes out from the container and, owing to the sharpened frusto-conical shape of the element I, can be spread in the most internal part of the external auditory meatus, in order to obtain the best way the therapeutic efiicacy of the employed prodnot.

The protecting container according to the invention permits easy transportation and easy conservation of the odontalgic device.

As the spherical form for the vial containing the analgesic fluid is the farm having maximum resistance it requires considerable stress for its breaking. Figs. 3 and 4 illustrate a different form of embodiment, wherein this stress may be more easily exerted.

In this case, the part i3 is substantially the same as the corresponding part described in the preceding embodiment, but the upper part [4,

instead of ending with a plane surface, so that all the screwing stress for breaking the analgesic vial may be concentrated on its cylindrical lateral part, has a projection l5, substantially of a conical shape, allowing the cover to be more easily gripped.-

The device has been shown in Figs. 3 and 4 without the absorbent element and the vial which are identical in both cases.

I claim:

1. A device for bringing in contact with the internal surface of the external auditive canal an analgesic fluid intended to. act on the innervation of the trigeminal nerve, comprising in combination a container provided at one end with a cap and at the other end with an opening, an absorbent material in said container and partially projecting from the opening of said container, a covering of absorbent material wrapping said projecting part of said absorbent material, a vial containing the analgesic fluid in said container resting on the absorbent material, and means in said cap of the container adapted to break said vial.

2. A device for bringing in contact with the internal surface of the external auditive canal an analgesic fluid intended to act on the innervation of the trigeminal nerve, comprising in combination a frusto conical container having at one end a cylindrical portion externally threaded and at the other end an opening, a cap adapted to be screwed on said cylindrical threaded portion, a pin integral with said cap and projecting inside said container, an absorbent material in said container and partially projecting through the opening thereof, a covering of absorbent material Wrapping said projecting part of said absorbent material, a vial containing the analgesic fluid in said container on said absorbent material, a rod integral with said vial and projecting therefrom, said rod penetrating into the absorbent material, said vial being in contact with said pin, said pin being adapted to cause breaking of the vial when the cap is screwed on the cylindrical threaded portion or" the container.

3. A device for bringing in contact with the internal surface of the external auditive canal an analgesic fluid intended to act on the innervation of the trigeminal nerve, comprising in combination a frusto conical container having at one end a cylindrical portion externally threaded and at the other end an opening, a cap adapted to be screwed on said cylindrical threaded portion, a pin integral with said cap and projecting inside the container, a cylindrical flange projecting from the cap and surrounding said pin spaced apart therefrom, an absorbent '4 material in said container and partially projecting from said opening of said container, a covering consisting of a sheet of absorbent material wrapping said projecting part of said absorbent material, said projecting part of the absorbent material and said covering being adapted to penetrate into the external auditive canal, a sealed vial containing the analgesic fluid arranged in said container on said absorbent material and adapted to partially penetrate in said cylindrical flange of the cap, a rod integral with the vial and projecting therefrom which penetrates into the absorbent material, said vial being in contact with said pin, said pin being adapted to cause the breaking of the vial when said cap is screwed on the cylindrical threaded portion of said container, whereby the analgesic fluid. contained in the vial is absorbed by the absorbent material and the said covering when the projecting part of the absorbent material and the covering are introduced into the external auditive canal.
