Patented May 6, 1941 UNITED STATES PATENT OFFICE THERMOINHALER C'olo.
Application July 6, 1940, Serial No. 344,275
(Cl. 12S-192) 8 Claims.
The present invention relates to inhalers and more particularly to thermoinhalers for use in the relief and treatment of head colds, hay fever and other conditions of the mucous membranes of the nasal passages and throat.
Heretofore the use of inhalers for the purposes stated by patients in sitting or lying positions has been attended with a great deal of inconvenience due to the possibility of spilling the liquid used in the treatment and to the awkward constructions of the inhalers. A further diiilculty has been the proper washing and sterilization of the inhalers after use.
An important object of the present invention is to provide a thermoinhaler which will not be subject to the disadvantagesl above mentioned Another object of the present invention is to provide a thermoinhaler which when used by the patient Will not merely alleviate his discomfort but will, when properly employed, relieve the pathological condition causing the illness and discomfort.
A further object of the invention is to provide a thermoinhaler which not only permits the suiferer to inhale fresh heated air but is also provided with means whereby the air may be treated by contact with water or a suitable medicament, such as eucalyptus, pine oil, menthol or similar recognized preparations beneficial in the treatment of the above mentioned conditions or ailments.
A still further object of the invention is to pro- Vide a thermoinhaler which is simple, inexpensive and easy to use.
With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.
In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views.
Figure 1 is a central vertical section through the improved device with parts shown in elevation.
Figure 2 is a vertical sectional View along the line 2-2 of Figure 1.
Figure 3 is a horizontal sectional View taken along the line 3-3 of Figure 1, and
Figure 4 is a horizontal sectional view taken along the line 4-4 of Figure l.
Referring more particularly to the drawing, the inhaler comprises integrally formed branch portions I0, Il and I2 which are in communication with each other at their inner ends and initially open at their outer ends.
'I'he branch I0 is preferably a hollow cylindrical casing of elongated form having its open end interiorly threaded for a short distance to receive a flanged screw plug I3 forming a detachable closure for same. At its inner face the plug I3 is provided with a socket I4 carrying an incandescent lamp I5 of elongated form and disposed within the branch I0 in spaced relation thereto. Electric current is conducted from any suitable source -to the lamp I5 by a cord I6 conventionally plugged to the electrical source to form a heating unit for the inhaler.
The lower end of branch I0 is provided with a number, preferably six, spaced apart perforations I'I for the purpose of admitting air into the branch I. These perforations I'I are so located with respect to the lamp I5 that the entering air immediately comes into contact with initial portion of the lamp and becoming heated rises in the branch I0.
A portion of the branch I0 is depressed as shown at I8 forming ribs I9 and 20 to accommodate an asbestos or other heat proof lining 2I. 'I'his prevents the conduction of heat to the external parts of the branch which thus serves as a handhold for the inhaler when in use.
The open end of branch I I is also interiorly threaded for a short distance to receive a anged screw plug 22 -to form a detachable closure for this branch. On its inner face the plug 22 is integrally provided with an open ended cylindrical container 23 which is disposed within the branch II. A shoulder or inset portion 24 on the container reduces the diameter of the container to something appreciably less than the diameter of the tube forming branch II to form between these concentric members an annular air space for the circulation of the heated air ascending through the branch or casing II).
The container 23 is disposed within the branch II to span the communicating port 25 of branch II. It will be noted at this point that branch II is provided with a neck 26 which permits the heated air to converge at the port 25 and its full effect is directed to the container 23. container 23 is provided with a plurality of slots 2'I which are elongated in the direction of length or axis of the container. 'I'he container 23 is adapted to contain cotton or other similar material 28 which is saturated with a suitable medicament or simply water which is thus held in suspension. The slots 2l expose the saturated cotton to the heated air current drawn through the branch Ill whereby the medicament or other fluid The will engage the cotton and by which the cotton may be pushed toward the open end of the holder for the-'purpose of ejecting same and freeing the interior of the holder for replenishment of fresh newly saturated cotton.
The open end of branch l 2 is not screw threaded but has a smooth surface to which is removably attached a face mask 29 of pliablev material such as rubber. integrally-formed 'with the mask is a nipple 3i] which .serves as an adaptor in securing the mask in the smooth open end portion of the branch i2. As rubber has a higher co-efficient or" friction than 'metal the adaptor 3S will be aided in frict'onally binding and remaining in the smooth end of the tube to be held `therein during use ofthe inhaler.-'1" t VIn use; thecontainer 23 is suitably provided 'wthsaturated cotton and screw threaded into the threaded porti'onof the branch H. The mask-29 is-'then inserted in thel opposite or smooth endoi the branch I2 by means of the be laden with any of the moisture or medicament therefrom.
It is desired to have small quantities of this heated unmoistened air for purposes of ease in breathing but the majority of tho air received by the patient should be mcistened or medicated. The arrangement of the by-pass orice 3i referred to with reference to the annular air space and the adaptor 38 is such that a small quantity of heated air Will cause to be commingled and mixed with the treated or moist air issuing from 'the annular air space in the adaptor before adaptortii. WUpon' connecting the cord f toy an electricalfoutlet the'lamp I 5 will become heated.'Y The'air entering the casing Il] through the perforations lI'I is drawn'upw'ardly through the casing in contact with the lamp l and 'heatreaching the mask and the patient. The breathing of the patient must be easy and natural and not labored at any time and not retarded or restricted by anything.
The insulated portion of the branch E!) serves as a handhold for the patient enabling him to hold the inhaler in an attitude and position which will be most convenient and ei'ective with relation to the mask and of course the patient. The spilling of medicament orv 'other iluid is avoided by providing the container 2S which receives cotton saturatedwith medicament.
Another advantage of the present invention is that the device may bereadily disassembled for the purpose of washingand sterilizationafter use by the patient.Y It will beseen that the heating element or'larnp Vl5 can be readily removed from the branch or handle lil; in a like manner the container 23 for the medicament is' readily removed from branch il of' the 'tube andv the mask 29 is likewise removable from' the' other branch l2 of the horizontal tube. When these parts have been removed all that remains of the inhaler is a T-shaped shell formed bythe branch and thereby causing a pull upon the liquid suspended 'in the cotton whichY volatilizesthe liquid and it becomes 4evaporated' into Athe heated air streams;
The construction 'of' the vbranch Hand "container 23andtherelative arrangement of these' two parts vwith respect to the annularair' space andwith respect'to the port 25 at'the top of the casingl i@ through vwhich the'heated air current moves is-suclr'thatthe heated air current is allowed a-great areaH in 'which' to expand in the lower portion of the' annular `air space' whereby thel heated air in relatively' large `volume all alongthe' axial length of the slots 21 may move out in two streams, `one on eachside ofthe container 23.As heretofore pointed out the `slots 21 oiTer very large exposed areas of the Vcotton to the two widely spread streams of air movin up on both sides of' the container 23 and this relationship and arrangement thus insures the entrainment in these heated streams of air of a satisfactory volume of moisture or medicament. Moreover ity will be noted that the right hand side of the annular air space is not interrupted or impeded by any parts but is continuouslyfree and wholly opento the mask. I-Iowever there is a by-pass orce 3S left between the upper end'of branch i9 and the adjacent open end of the container 2,3 to avoid an undue quantity of 'heated air by-passing the saturated cotton as such. by-passing air would naturally not come under the influence of the cotton nor Iii and branches l l and l2, and the immersion of the shell in a body of sterilizing liquid permits all parts of the shell to be thoroughly sterilized or washed.
The inhaler body may be of any Suitable material such as metal, Bakelite, etc. and while insulation has been shown as applied only exteriorly on the branch H3, it will be understood that the insulation may be interiorly only of the "branch or both interiorly and exteriorly to prevent the conduction of heat to the external parts of the casing which serves as a handheld for the inhaler.
Itis obvious that various changes and modifications may be made in the details of 'construction and design of the above` specifically described embodiment of this invention without departing from the spirit thereof,"such changes and modications being restricted only by Athe scope of the following claims.
