FacIAL INHALEB.

Application illed September 9,'19'12'. Serial VIlo.. 719,88*@7..

Be it known-that I, CHARLES TETER, a citizen of the United States, residing at Cleveland, in the county f Cuyahoga and, State of Ohio, have invented certain newA hand useful Improvements in Facial Inhalers, of which the following is a specification. ,i v y y My invention relates to improvements in a facial inhaler, designed for .use in connection with anesthetizing apparatus, and has for `its object the provisionnrst, of an inhaling device, which will self-adapting to thefeatures of the patient, for the purpose of excluding the air; second, which will permit-the observation of the patients features, for the4 purpose of detecting any retching; third, which provides a positive, adjustressure-valve, and finall one which may e readily and efectually sterilized. The structural details of myimprovement will be more readily understood, 'by making4 reference to` the accompanying drawings, wherein i Y Figure I, is a view in side elevation of my im roved facial inhaler.

igs. II, andlII,l are enlargedflongitudinal sectional Niews of the adjustable positive pressure-valve, preferably employed therein.

' terial, prefere l Fig. IV, is a transverse sectional viewof said valve on line IV-IV. i Fig. V, is an under-side plan view, pary tiallybroken away, of my improved inhaler,

and v v Fig. VI, is an enlarged fragmentary kview of the, pressure-gage. ,i Throughout the several figures of the drawings, I have employed the same character of reference to indicate similar parts. y

In order kto observe the features ofthe patient at all timesI provide a substantially bell-sha ed body a of transparent mab celluloid. About the outer rim of said y, there is secured the oval pneumatic -cushion b, providedA with a substantially 'circular Vapron e integral `therewith, and formed of soft rubber. The said apronfits closely upon the lower edge or l trim of the body a, while the pneumatic cushion, which is adapted to be injlated through the valve d, provides a self-conforming member, Vwhich fits over the nose t t `This is important,

' and about the mouth ofI the patient, so

closely, -as ,to exclude the air therefromg" Under these circumstances, 'the `patient is compelledto breathe the anesthetizing va# ors or gases supplied to thebell-shaped body, through the angular-duct e.` In orderI to maintain apositive, determinable pres@ upper surface of the body a. Accordingly,`""`

these members are so disposed as to-'aiord the least interference with the observation by thesurgeon of the patients condition, through" t-heltransparent Celluloid `walls a.

This material is preferred, not only because of its transparency, but it is light in weight,

` flexible and yet suilicientffly rigid, to mount the valve and duct thereon y In order to increaselthe absorption by the blood, of theanesthetizing gases .or vapors,""""

for

the positive pressi'l're-valve is insuring a constantpressure wlthin the respiratory ordans of the patient. This valve comprises t e aluminum disk gv normally 'closing the valve-opening, under the tensioni* of spring li, positioned interiorly of the slotted tube i. At the sideof said tubeis :a graduated scale indicating the compression of the spring, necessary toA securegas pressures ranging between two" (2)` and-U1x ytwenty-four millimeters, for example.` The exterior sleeve j has `a set-screw k which turns within the cylindrical plug'l` positioned rabove the upper end of` spring Thus the valve may be set at any des1red"-` pressure, and will require'no attention `upon the part of the operatori" It willbe observed that'the valve-partfor disk gis provided with'a relatively longdepending stem m, 4which slides readily'with-l in the `sleeve ln, but serves to center said disk g, and seat it closely and evenly,to `fclose the valve-opening.

The valve and duct are removably secured to the Celluloid body, by means of interposed rubber washers @,and interior screw rings 71,' `which afford substantially gas-tight' joints between these parts. i for theieasonfthat/an essentially novel and distinct method of wherein super-atmospheric pressure is s'e cured by suitable means.

VInasmucli as my inlialer is adapted to close or cover both the nose 'and mouth, while a definite adjustable gas-pressure may be maintained therein. and in the respir atory organs of thepatient, it is clear that the lungs willnot suffer collapse but may be distended thereby, throughout anesthesia or indeed, as long as is required. lMoreover,

Vsuch pressure is subject at all times to the control or accurate regulation of the surgeon or operative, dependent upon the varying condition of the patient.

It will be lobserved that ythe pneumatic cushion is disposed immediately beneath the 'edges` of the Celluloid body-portion,` Iwhereby the pressure upon the face of the patient may e light and yet suflicient to permit any necessary working-pressure for the anesthetic.

Casual consideration will show that all the parts of my inhaler are readily accessible for inspection, replacemeiit'or adjustment, and that they are so designed as to permit of very ready and effectual sterilization. The rubber cushion and apron may be replaced at small cost, while thev other parts are not subject to deterioration or damage from ordinary use. i

Having nowV described the preferred em bodiment of my invention, I claim as newv and desire to secure'by Letters Patent, the following 1. The-combinationwith an inhaling device having an inhaler-member, of an associated valve affording a relatively large clearance therefor; a spring normally acting to close said valve, an adjustable part for `varying the `tension exerted by the spring against the Valve, a slotted casing for the spring, and a gage associated therewith; all visibly and accessibly mounted upon the inhaler-member, substantially as sot forth.

2. The combination with an inhaling device, having an inhaler member and a free valve opening, of a valve-part normally closing the same, a slotted tubular casing above said 'valv` -part, a relatively .long spring therein ating against said valvepart, a member `extending through said slotted casing for varying the tension of the spring, and means for securing said member at predetermined points alongsaid casing for insuring positivelpressure Within the inhaling device; all` visibly and accessiblymounted upon the inhalen-member, substantially as set forth.

3. In an inhaling device, the combination justable spring governing valve, a gage and mea-ns for setting the ten- 1,247.4,ee1- y with -a substantially bell-shaped body-portion formed of celluloid and free from obstructing members externally and internally thereof, of suitable inlet and outlet niembers connected therewith, and a soft rubber apron equipped vwith a. peripheral pneumatic ciishionysaid cushion being normally positioned beneath the lower edges or riin yof said body-portion,substantially asset forth. 4. In an inhaling device, the combination with a substantially bell-shaped body-portion, formed 4oftransparent material having unobstructed Sides, of suitable inlet and outlet members connected therewith, a peripheral pneumatic cushion positioned adjacent to the rim or edges of the Abody-portion, and
