APPARATUS FOR INHALING'IVIEDICINAL VAPORS, 86C.

SPECIFICATION forming part of Letters Patent No. 376,819, dated January 24, 1888. Application filed Septembzr 27, 1887. Serial'No. 250.845. (No model.) I

To all whom it mayv concern:

- Be it known that I, FREDERICK HARRISON GLEW, of 30 Conduit Street, Bond Street, in

the county of Middlesex, England, have invented certain new anduseful Improvements in Apparatus for Inhaling or Injecting Medicinal Vapors, Gases, or Powders, of which the following is a specification.

In the construction of an apparatusaccord IQ ing to my invention I employ a large-mouthed bottle or vessel of glass or other suitable material, the mouth of which I close with a suitable stopper or plug. In this stopper or plug I secure in any convenient manner three or more tubes, in two or more of which I place any suitable porous material, such ascylinders of pumice or Woven cords of asbestus saturated with the chemicals to be used in the formation of the remedial agent -say, for ex-. ample, chloride of'ammonium or the remedial agents themselvesto beinhaled. Theremaining tube, which is to be used as a suction tube, I construct with its inner end enlarged to form a receptacle for a sponge within the I bottle or vessel.

The porous cylinders or cords, the Sizes and lengths of which. are adjusted so as to take up the requisite proportions of the chemicals necessary to formthe proper combination for 0 inhalation, are,when charged, placed in their The sponge placed in the.

material, C, which carries the chemical substances for forming the compound remedial agent, and D is the suction-tube, thelower end of which is enlarged to receive a piece of 5 sponge, D. I To the other end of this tube D is secured a flexible tube, D, provided with a suitable mouth-piece, D or instead of this flexible suction-tube an enema or a pump may their respective tubes for the purpose of being contact with each other. Consequently the be attached for the purpose of injecting in' place of inhaling the remedial agent. In order to prevent mistakes in charging the porous materials,I make the tubes 0 of colored glass, and the tube 0 ofwhite'glass, and in sending out theapparatus I place the chemi' cal substances in similarly-colored bottles. f

The pieces of porous materiahG are each provided with a small piece of suitable 'wire, by means, of which they may be withdrawn from recharged I I An inhaler constructed as above described embodies all the good qualities of other inhalers, and as all the working parts are contained within the inhaler itself they are protected from breakageand the inhaler is sim- 165 plified in construction.

One importantadvantagein this construction is that bodies of liquids are dispensed with, a damp sponge being used in the Suctio'n-tube instead of a body of water, in the-7o vessel A to absorb any excess of vapor, whether of ammonia or acid. Atthe same time the gurgling noise which ensues whenairis drawn through a liquid is'avoided. The

effortof suction is also reduced to a mini- 7 5 i mum, as the bottle A contains no body of water. There is also no loss of vapor of chloride of ammonium through absorption in that liqu'idand no deterioration of the agents from product is uniformly as neutral as it can be practically obtained for inhalation. 1

Another advantage that this form 0t: in-

haler possesses is, that if inadvertently the patient should, instead of sucking, blow into the .8 5

apparatus (a very common mistake) no inconvenience can result; "neither can the acid or ammoniabe damaged. 7 A further advantage is that the apparatus affords facility 'for the use of remedial agents in the form ofpowder. o When'em'ploying such agents,a piece of dry sponge is placed in the enlarged receptacle provided at the lower end 01 the suction-tube, and powdered remedial agents may beplaced at the bottom of the vessel A, the draft of, air 5 caused by suction being in such cases ufficient to stir up and suspend them in the body also fitted to said stopper, and having its in of theinhaleigand their filtration being effected ner end enlarged to form a receptacle for a by their passage through the dry sponge into sponge, substantially as herein described. the suction-tube.
