To all whom, it may concern:
Be it known that I, YANCEY Q. CALDWELL, a citizen of the United States, residing at Paris, in the county of Henry and State of Tennessee, have invented new and useful Improvements in Inhalers, of which the following is a specification.
This invention relates to inhalers for the application of medicaments through the naris for treatment of the nasal cavities and general organization thereof, including the membranes and the throat and lungs, by forcing an inhalent through the naris, and thus increase the range of treatment.
The inhaler is simple and eifective in its construction and may be conveniently applied and when in use fully excludes the inhalation of the surrounding air by the patient.
The inhaler embodies, essentially, but two partsthe body and the closure at the lower end of the body, the said closure remaining intact with the body, except at such times when it is necessary to replenish the chamber formed in the body with a medicated inhalent. The one extremity of the inhaler is shaped to closely fit against the nose and upper, lip, and all air, except that which passes through the medicated chamber, is shut oif from the patient. In the use of the inhaler the patient is not subjected to the least inconvenience or discomfort, and when it is desired to dispense with the application of the improved device it may be conveniently disposed in the vest-pocket by the user in view of the compact form and minimized proportions of the several parts embodied in the inhaler organization. In View of the fact that the inhaler is composed of but two essential parts cleansing operations can be readily pursued with respect thereto, and such material will be used in the construction of the parts as to render the inhaler strong and durable and especially adapting it for use by small children.
In the drawings, Figure 1 is a perspective view of an inhaler embodying the features of the invention. Fig. 2 is an elevation of the inhaler looking toward the side opposite that shown by Fig. 1. Fig. 3 is a section through the inhaler. Fig. 4 is a perspective view of a slightly-modified form of the inhaler. Fig. 5 is a section through the inhaler shown by Fig. 4.
Similar numerals of reference are em ployed to indicate corresponding parts in the views.
Referring to both forms to the inhaler,the numeral 1 designates a cylindrical stem of considerable diameter, continuing into a laterally-extended body 2 at one extremity, the body being provided with oppositely-projecting arms 3, which are partially intersected by a cavity 4. The body 2 at one side of the inhaler is formed with a cavity 5, corresponding to the contour of the human physiognomy defined by the lower portion of the nose. The cylindrical stem has a chamber 6 formed therein for the reception of absorbent material adapted to receive a liquid inhalent or medicament, or may receive medicated powder or any. other material desired to be administered to a patient by the use of the inhaler. A pair of apertures or openings 7 extend through opposite sides of the center of one terminal of the cavity 5 and communicate at their lower portions with the chamber 6, said cavities being so positioned as to be effective in delivering medicated air or powder from the chamber 6 to the nostrils. A screw-threaded closure or plug 8 is adjustably mounted in the free end of the stem 1 and is provided with a milled head 9 for operating the same to regulate the admission of air to the said chamber. The body of the plug is hollow, and communicating with the interior thereof are a plurality of apertures 10, which are exposed more or less to the exterior air by the adjustment of the plug. The cavity 4 provides for the reception of the upper lip, and when the inhaler is applied and pressed closely against the upper lip the nostrils will be completely closed so far as inhaling the adjacent air is concerned and will be over the openings 7, and by this means the inhalations will ensue solely through the chamber 6, and thus insure a full administration of the medicament desired to be brought into contact with the nasal organization and throat, as well as the lungs, to allay inflammation and benefically treat other diseased organs of the nose and throat.
The arms 3 are particularly essential in the application of the inhaler in view of the fact that by pressing against the outer sides thereof a firm contact will ensue between the nose and upper lip and the surfaces of the cavities 5 and 4. The outer parts of the arms 3 are rounded to avoid inconvenience in engagement therewith. The arms and the remaining parts of the inhaler, including the stem 1 and body 2, have a T-shaped contour, and the object sought in this particular instance is to provide means at one extremity of the inaler for securing a perfect application thereof and without requiring the stem 1 to be held by either hand, particularly adjacent to the plug, and which would have a tendency to obstruct the entrance of air through the body of the plug into the chamber 6. Either one or both hands may be used in holding the inhaler 'appiied, but pressure will be exerted in either instance against the outer sides of the arms, as hereinbefore stated, the main object being to exclude the entrance of air into the nostrils from any other point except through the apertures or openings 7.
Thus far both forms of the inhaler shown in the drawings are precisely the same in structure, the particular difference being that the inhaler shown by Figs. 1, 2, and 3 is formed with nostril-plugs 11 at the inner part of the cavity 5, said inhaler-plugs having the apertures or openings 7 continued therethrough, and said apertures or openings inclining inwardly and domiwardly to the adj acent end of the chamber 6. Furthermore, in both forms of the inhaler a rim 12 surrounds the cavity 5, said rim being more pronounced in the form of the inhaler shown by Figs. 1, 2, and 3 and continuing into an outer curved member 13 and extending inwardly to the inner surfaces of the arms 3, as at 14. The cavities 4 and 5 in the forms of the inhaler illustrated by Figs. 1, 2, and 3 are also deeper than the similar cavities of the inhaler shown by Figs. 4 and 5.
The improved inhaler may be readily charged with absorbent material and medicaments by removing the plug, and it will be understood that any form of inhalent desired to be used may be introduced in the chamber.
Any material may beemployed in the construction of the inhaler but for many purposes hard wood or vulcanized rubber will be preferred, wood being easily worked to the shape shown, and therefore more economical in the cost of manufacture than if the device was made of rubber.
When not in use, the plug may be closed against the free end of the stem 1, and thus materially obstruct the evaporation of the medicament in the chamber 6.
The improved inhaler in both forms is ex ceptionally convenient for use and will always be ready for immediate application.
Changes in the proportions, dimensions, and minor details may be resorted to without departing from the spirit of the invention.
Having thus described the invention, what is claimed is- 1. An inhaler comprising a chambered stem and arms disposed in planes at right angles thereto, the bod of the inhaler between the stem and arms being laterally projected and having on one side a nose-cavity pr0ject ing over the stem and provided with apertures opening therethrough and in communication with the chamber of the stem, the arms being intersected at the inner edge portion thereof by a lip-cavity, and an apertured plug adjustably fitted in the free extremity of the stem to control the admission ofair to the chamber.
2. An inhaler having an upper cavity adjacent to one extremity shaped to receive the lower part of the nose, and arms projecting in opposite directions intersected at the inner edge portion thereof by a lip-receiving cavity, the lip-receiving cavity continuing into the upper nose-receiving cavity, a chainbered stem projecting from the inhaler and provided with adjustable air admitting means, the nose-receiving cavity being provided. with aper ures communicating with the chambered stem.
