Patented Aug. 11, 1931 01111 sn S1 11 1115 ALBERT M. ALLEN, OF ST. LOUIS COUNTY, MISSOLTRI NASAL INEIALER Application file:l December 31, 192%.

My inventin is directecl 10 improvements in nasal inhalers particularly f0r application 130 the n0se 111 such manner that the inhaler Will be self sustaining. The vari0us 10r111s 0f aton izers, sprayers, ancl inl1alers 110W in use a1e aclaptecl f01 use whereby perioclical treatment 1nay be efiectecl by holding the device t0 ehe nostrils andL injecting 01 inhaling the prescribecl meclicine 0r antiseptic. Experience has sh0wn that the fra1lties 0f human nature cause such treatn1ent to l0e neglectecl whe11 inconvenienee attencls the application 0f the 1neclicine. F01 this reas011 I have s0ught t0 provicle an inhaler that 1nay be aclapted to the n0se similarly 150 the wearing 0f a pair 0f spectacles, and tl1e vap0r fr0n1 the therape1ltic agency containecl within the inhaler Will be continuously inl1alecl. A. further aclvantage 0f the device is that 113 may be employecl 111erely as an ai1 strainer 111 localities where the atmosphere is heavily laden with sm0ke, 0r 0ther noxious gases. Further and 0the1 aclvantages will be better apparent fr0111 a cletailed descr1ption 0f the invention in connection Wih the accon1panying clrawings, in which:

Figure 1 is a pictorial view 0f a face with n1y improved inhaler mountecl 0n the wearers 110se; Fig. 2 is a t0p view 0f the inhaler;

Fig. 3 is a front view thereof; Fig. 4 is a sicle view 0n an e11largecl scale with parts broken away and 0thers in section; Fig. 5 is a cross sectional detail taken 0n the 11110 5-5 0f Fig. 4; Fig. 6 is a cross sect-ional cletail taken 011 tl1e line 6-6 oft Fig. 4:; ancl Fig. 7 is a detachecl view 0f tl1e absorbent cartriclge which is impregnaecl with tl1e meclicament f0r supplying the vap0rs that are 130 be inhalecl.

Referring 130 the clrawings, l, 1 are oval shaped tubes each having an open t0p 2 adapted t0 be closed by a cover 3, anal an up- Warclly bent lower extrernity 41 having an open encl 5. The tubes l, 1 are connectecl by a spring spectacle briclge 6 in such spacecl relation that wl1e11 the bridge is placecl up011 the n0se the tubes l, 1 will fiat against the sicles of the nose ancl the extremities 4, 41 may be insertecl in the nostrils (as sh0wn in Fig.

1). Bach 0f the tubes are provicled with an inlet opening 7 011 the outsicle 01 the Wall ancl Serial N0. 329,332.

so s 10 cover the onening 7. The purpose tl1e cage 8 is 10 hold in plane a cartriclge 9 which is 1'01111ed 01? a l00sely packecl cylinder 01 l1igl1ly absorbent cotton, or other material, 111 Wl1i011 is disposed a pair 0f zig-zag reenforcing wires 10, 10 130 serve as a core :Eor the cart-riclge so tl1at it may 11013 be easily c-a-111pactecl 011 placing it 111130 the cage 8. It is essential that the cartridge 9 be protected against 00111p1ess1011 since the cotton compos- 111g the cartridge serves as the vehicle for the 111eelicament, and the 1nore freely the inhalecl air passes tl1rough the cartridge, the more vap0r is carriecl through the tube i11t0 the nostrils, ancl tl1e less restriction is in1posecl upo11 t-l1e inhalations.

Obvi0usly, the exhalations must also be dischargecl through the tubes l, ancl at the same 131111e must n0t be a'llowed 130 be clischargecl through the cartriclge, as this would speeclily clissipate the n1eclicament ancl at the san1e tin1e restrict the free expulsion 0f the gaseous proclucts fr0111 ehe lungs. A relief valve 11 in the l0r111 01 the hingecl clisc is mounted over an opening 12 in each tube immecliacely below the inlet 7, saicl valve being held its seat b *y a lig'ht coilecl spring 13 coilecl about the hinge pin 14 0f the valve ancl l1aving 011e e11cl bearing 011 the tube l ancl the other bearing 011 the valve (as shown in F ig. l). The pressure 01' the spring 13 is so slight that it Will 11013 offer noticeable resistance t0 the open- 111g 01 the valve unde1 the pressure 01 the exhalations but Will serve to prevent tl1e valve from flapping with movements 0f tl1e heacl.

Obviously, the cletails 0f construction are subject to 1noclification, a11cl I (310 n0t wish t0 be restrictecl t0 the precise features herein sh0wn, but wish t0 avail 1nyself 0f all modifications 0f which the invention is susceptible.

Having cleseribecl my invention, I clain1f l. A nasal inhaler comprising a pair 0f spacecl tubes aclaptecl lie again'st the sides 0f tl1e 110se, a bridge member connecting the tubes ancl aclaptecl t0 engage the nose, each tube having an upwarclly bent extremity 111- sertable in the nostril, and an air pervi0us cartridge in the upper part 0f each tube, each tube l1aving an air intake adj acent 130 the 021r- 1 wire ganze cage 8 is fixecl within ehe tube tridge, u dischurge vu1ve for the exhulution products disposed in the 10We1 purt of euch tube, u coi'led spring udupted t0 hold euch vulve 011 its seut, the tension 015 the spring being such thut the vulve Will reudily 0pe11 under the pressure of the exhulution products Within the tube.

2. A nasu1 inhuler comprising a puir of spaced tubes udupted t0 lie uguinst the sides 0f the nose, u bridge member connecting the tubes und udupted to enguge the nose, euch tube huving an upwurdly bent extremity insert-uble in the nostril, und an uir pervious cartridge in the upper purt of euch tube, euch tube huving an uir intuke udjucent the eurtridge, u dischurga vulve for the exhulution products disposed in the lower purt of euch tube, suid vulve being udupted to open under the p1essure 0f the exhulution products within. the tube, und close when suid pressure is removed.

In testimony whereof I hereunto ufiix 1ny signuture.

ALBERT M. ALLEN.
