VITTORIO EMILIO EVIECHMANN, OF FLORENCE, ITALY.
The present invention relates to a vaporizcr or atomizer intended more particularly :for producing medicated vapors for inhaling in the treatment of patients.
One olf the princilml objects of the present invention is to provide an atomizer which will produce a nebula olf very line dry vapor from liquids oit' all classes, particularly those ot' Van oleagiuous nature, and which at the same time can be used for the ejection o'l" a coarse spray.
Another object is to provide an atomizer which may be constructed almost entirely ol glass so as to permit ready inspection and cleansing 'ot' the interior thcreo'l.
A l'urtliier object is to provide an atomizer which may be freely carried about when tilled with liquid without danger of spilling the contents.
The apparatus consists in the container, for the liquid to he vapor-ized, and is provided with a small blow-pipe to which is attached an aspirator immersed in the liquid, the liquid emerging from the mouth of which is converted into spray by the continuous jet of air proceeding from the blowpipe. Both these organs open into a bell, chamber, or the like` within which is formed the nebula (or dry and cold vapour), which nebula, by means of the pressure arising within the apparatus, is expelled therefrom, passing underneath the edges ot the bell, and after circulating through the empty space between the bell and the external vessel, emerges from an appropriate duct. The liquid, converted into spray, but not yet into an actual nebula. but into small particles or drops, is dashed against the inner walls olsaid bell; and, condensing, drips back into the container; thus, while only thc nebula ot the medicated or other liquid escapes regularly` every drop of the liquid is intercepted and recovered.
This tact is obviously due to the location of the bell in the interior ot the apparatus and the positioning oit' the upper portions oi. the air and liquid tubes within said bell.
The accompanying drawing shows a practical example ot the invention. Therein:
Fig. 1 indicates the apparatus, as a whole, comprising the bulb, in a front view;
Fig. 2 in vertical section;
Fig. 3 in a side View.
The apparatus is composed of a container -a- (preferably ot' glass) supported at its lower portion by a base -b and provided with a mouth om :lor insertion in the duct connected io a bulb Wd-- Said mouth -cis in communication with a small tube or pipe cending at its upper part in a comparatively small aperture. Said tube or pipe acts as a blowpipe and carries, attached thereto, another small pipe -fextending into the liquid to be atomized, and whose upper end slightly snrmounts the mouth ot the blow-pipe.
ln the upper portion of the container tz-M, is located the organ .intended to intercept the drops, namely, the bell Mgwhich covers, to a certain extent, the ends ol' the two tubes or pipes -e-, f--.
The upper part ol' the bell g/ communi rates with the mouth /t for the purpose oi introdiuaing liquid into the container or for the ejection o l' a coarse vapor therefrom, a stopper being provided :lor closing` the mouth when the atomizcr is used 'tor line spray.
A lateral duct -iservos tor the expulsion oi' the atomizcd liquid.
The liquid to be atoinizcd having been introduced into the container in such a quantity that the small tube or pipe --f is freely immersed therein, air is admitted, by means of the common bulb -cl-, into the duct o-. The air, passing through the small tube or pipe -c and escaping :from its upper vent, brings about suction in the small tube or pipe "fm, which d 'aws in the liquid in which it is immersed and causes it to issue Yfrom its lupper mouth, upon which as already stated-it becomes atomized.
The nebula thus produced in the .interior ot the bell b-gm passing beneath the latter has stated-is thence expelled from the small tube or pipe im through the pressure oli the air, and the drops eventually formed as a result oit the liquid escaping from the upper month olf -f are dashed against the walls et said bell, being thus intercepted and 'falling bai-.lc into the container.
'lbus the nebula is left devoid ol any drop which, where medicated liquid, o1' the like, is concerned, might injure or irritate thc mucous membranes or cavities which the nebula is .intended to heal.
An atomizer -tor vaporizing liquid comprising a container for said liquid having an elongated openingl in its top, a bell shaped member vertically suspended within the con taincr having its lower end positioned above lthe normal liquid level in said container and having in its top an opening 'forming a continuation of said elongated opening, a Stopper for closing` Said elongated opening, atomizing `means Communicating with said liquid for discharging atomized liquid into said member, a laterally disposed discharge tube Communicating with the container at the upper portion thereof and adapted, when i@ said elongated opening is closed, to discharge the vapor escaping thru the bottom of said member, said elongated opening` forming the inlet for admitting liquid into the container and an outlet for the ejection of a coarse vapor therefrom When said stopper is removed.
In testimony whereof I have signed my name to lthis speeiieation.
