' UNITED} STATES PAT ENT OFF CE MEDICAL APPLIoAToR son THE NASAL 1 PASSAGES Q 1 Claim.
This invention relates to medical applicators for the nasal passages.
It'has long been recognized by physicians, and others, that certain diseases, as coryza or common colds, catarrh, headaches, influenza and many like disordersof the-nasal and olfactory tracts might be prevented if suitable medications V head of the person undergoingtreatment is genwere brought in contactwith the mucous membranes lining the-nasal passages and-that alleviation is obtainable even after the organisms of v the disease have entered, and recently it is known that the dreaded infectious malady, called acute anterior poliomyelitis or infantile paralysis, is caused by microbes entering the system through the nose.
. tThe nasal inhalers, known to the public, fail as proper applicators for nasal medicaments for several reasons: first, due to their construction they are unable to extend into thje nostrils a sufficient distance to deliver the substance, allocat ed for treatment, tosuch depths as is desirable;
second, by reason of their rigidity-and fragility if of glass-much discomfort attends'their use, and in addition to the pain accompanying their insertion, may become broken and highly dangerous; third, their shape is seldom or never such as to fit the upper part of the nasal passage, and finally, it is difficult to, deliver a charge of the selected medication throughlthem without waste or messiness.
Having these matters in mind, it is an object of this invention to provide an applicator shaped of'the nasal passage, and, furthermore, is soft to suit the interior of the nostriland adapted to be deeply insertedtherein. Y
A further feature is in the provision of an applicator, the body of which, in addition to its ability of carrying a charge of medicament, is extremely flexible andyielding to the sinuousities so that 'no abrasions canoccur.
Another purpose is to produce an applicator for nasal medicationthat can be readily handled, and having means to, gently force the sub: stance with which it is charged into positive i 'contactwith the desired point of application, such means consisting of a detachable, compressible drawing, constituting a component of .this disclosure, and in which:
Figure 1 is a general view showingan application of an embodiment of this invention.
Figure 2 is a longitudinal sectional view of 1 the applicator'as engaged with a container.
Figure '3 is an end elevational View of the applicator. I r
Figure 4 is a transverse sectional view of the 5 medicament carrying element of the applicator.
,Referringin greater detail to the drawing, the
This container may be provided at its mouth with a screw thread I8 to receive an internally threaded annulus having an integral stopper flange 2! provided with a raised hollow nipple 22 having an annular rib-'23 by which may be I engaged the stem 24 of an ordinary compressible bulb 25.
Reaching oppositely, downward from the flange 2| is a reduced plug 26serving as a mandrel to which is attached the applicator element 21, the same having av straight axial passage 28 in open communication with theaperture 29 in the element 2 l The applicator is composed of flexible compressible material, as soft rubber and, as'shown in Fi'gures'3 and4, is generally of an elongated rectangular cross section with rounded corners, approximating the'cross section of a common nasal cavity, while its length is such as to fully extend to the cribriform plate or bone at the extreme inner end thereof.
The applicator tube. 21 is' capable of containing a considerable quantity of the medicament, and by reason of its shape, closely fitting the nasal cavity, convey the menstruum'to the proper point of application, where, upon compressing the bulb, it is gently forced outward from the end of the tube. 1 It will be understood that in some forms of applicators, the bulb may be eliminated and a collapsible tube substituted, such as is ordinarily used as a container for medical specialties, suited to the conditions, thus applying'the remedy direct to the applicator element 21 in apositive man- It win be furthernoted that no possible injury. can occur by reason of the smooth exterior and pliability of the applicator, as can readily be seen. i I
Having thus described the invention, and set forth the manner of its construction and appli- 10 liptical cross section having one of its ends mounted on the reduced extension, the bore of the nozzle being'enlarged at one end toreceive the reduced extension, said nozzle being adapted to enter the outer end of the nasal passage and being of considerable length and having its terminal rounded at the periphery, whereby the applicator may be advanced relatively high into the passage so as to reach an area in the vicinity of the cribriform plate.
