INHALING APPARATUS.

' Application filed May 4, 1920. Serial No. 378,925.

To all whom it may concern:

Be it known that I, DANIEL RICHARD Coornn, a subject of the King of Great Britain and Ireland, residing in Gore, .in the DGIl'lll'llOn of'NewZealand, have 1nvented a new and useful Improvement in Inhaling Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to that class of apparatus employed for inhaling medicinesof a vapourizing nature, and more particularly useful in connection with medicines that are.

used by the inhalation system for the treatment of nasal, throat and chest complaints and diseases. I

The object of the invention is to permit of. the vapours from medicines of a volatile nature being easily regulated, and any suitable combinations of the vapours from such medicines inhaled with any desired admixture of air, either through the nasal passages or by means of the mouth.

The invention will be fully described. with the aid of the accompanying drawings, in which Figure 1, is a sectional side elevation.

Figure 2, is a similar view showing a combined mouth and nose piece.

Figure 3, is a side elevation partly in section showing a form having air regulat ing means thereon.

Figure 4:, is a plan in which a double nose piece is employed.

Referring to the drawings, the inhaler consists of a casing 1 made of suitable material and having an air or vapour passage 2 extending longitudinally through the lower portion of the casing 1. Chambers 3 are arranged in the casing 1, each of which opens out through the top of the casing 1 and is furnished with a stopper 4: havlng a passage 5 into which a plug 6 fits. Any desired number of these chambers may be employed, the drawings showing three. The bottonr end of each chamber communi cates with e air passage 2 by an orifice 7 so that whe anyone of the plugs 6 is removed, a passage for air is formed through the corresponding chamber 3 into the air passage 2. The ends of the air passage 2 are respectively provided with a removable nose piece 8 and mouth piece 9. These respective nose and mouth pieces are shaped as shown for enterin the nostrils and mouth of the user, and have passages 10..

adapted to be closedby plugs lljfitted there in in order. that either may be closed at. will. If desired, the mouth and nose-pieces may be made in one as shown in Figure 2, so that by reversing this unit it may be employed for either purpose. By this arrangementthe mouth and nose piece,afterbeing used is reversed and the end which is insert edinto the air chamber is sterilized by means of the vapours within the air passage.

The chambers 3 are adapted to receive and hold a quantity of cotton wool or other absorbent, which is saturated with the desired volatile medicine, and this Wool is preferably retained in a holder whereby it may be easilyinserted and removed. 7

A suitable holder is shown in the figures and consists of a helical wire cage 12 fitting loosely into the respective chambers 3. Such 1 form of holder ensures that the air currents Will not be blocked, and at the same time provides that such currents will come into intimate contact with the saturated absorb ent and therebytake up the maximum quantity of the medicine vapour. In use, when the vapours from one medicine chamber only is required, the'plug 6 from the stopper is removed, but the plugs from the stoppers of the other chambers are left in position and the air is drawn through the one chambervapourizing the medicine and carrying the vapour to the nose or mouth. v

If the air is desired to be drawn through two or more chambers, the respective plugs of these chambers are removed and the air drawn through them. If desired, and in order topermlt the air current to pass equallythrough each absorbent the holders 12 may be removed from the chambers and placed. in the air passages 2 as shown in Figure 1 and an air current induced through one chamber and through the holders and absorbent material placed in the air passages.

In Figure 3, the chambers 3 are made with circular tubes to receive caps 14' having air inlet orifices 15 corresponding to air inlet orifices 16 in the wall of the chamhere. By these means theair may be regulated to each chamber. In Figure 1, a nose piece is employed'having branches 17 and 18 for insertion into each nostril.

What I claim is l. Inhaling apparatus comprising a casing, an air passage extending longitudinally through the casing, a nose piece fitted into said passage at one end thereof, a mouth piece fitted into said passage at the other end thereof, chambers in said casing to receive absorbent material adapted to be saturated with the required medicine, a passage from each of said chambers to the said air passage and means for admitting air to the said. chambers and for closing the ends of the said chambers from air, said mouth or nose piece removable from said passage, substantially as described.

2. Inhaling apparatus comprising a casing, an air passage extending longitudinally through the casing, said passage at one end thereof, a mouth piece fitted into said passage at the other end thereof, chambers in said casing to receive absorbent material adapted to be saturated with the required medicine, a passage from each of said chambers to the said air passage and means for admitting air to the said. chambers and for closing the ends of the said chambers from air, and a holder Within said chambers for containing absorbent material, substantially as described.

3. Inhaling apparatus comprising a casing, an air passage extending longitudinally through said casing, a removable nose and mouth piece fitted into said passage, said a nose piece fitted into passage adapted to contain absorbent material adapted to be saturated with the required medicine, chambers above said passage of a diameter corresponding with that of the air passage to receive absorbent material, a passage from each of said chambers to the said air passage and the upper portion of each chamber having closure means so that air may be drawn through one or more of such chambers, said nose and mouth piece made in one piece and reversible in said casing, substantially as described.

4. Inhaling apparatus comprising a casing, an air passage extending longitudinally through said. casing, inhaling means fitted into said passage, chambers in said Casing to receive absorbent material adapted to be saturated with the required medicine, a passage from each of said chambers to the said air passage, caps screwing upon the tops of said chambers, air orifices in said caps and in the walls of said chambers whereby the air supply to the said chambers may be regulated, substantially as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL RICHARD COOPER.
