Specification of Letters Patent.
Patented Dec. 15, 19141.
Application filed December 29, 1911. Serial No. 668,456.
To all whom it may concern:
Be it known that I, HUGO BAYER, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Apparatus for Inhalation Purposes, of which the following is a specification, reference being had therein tothe accompanying drawing.
The present invention has for its object apparatus intended for inhalation purposes, for regulating the normal respiration or for producing artificial respiration, and by means of which, according to requirements, either normal or ozonized air or air mixed with oxygen or medicinal substances in a vaporous form canbe applied.
By means of a special device the quantity of the air supplied at each respiration can be varied and the supply of air and its exhaustion which takes place during the inhalation and exhalation periods can be sub-divided into a number of phases so that the inhalation and exhalation process takes place in pulsations. r
The present apparatus presents the advantage that the kind of respiration depends upon the operation of the apparatus and not, as is the case with inhalation apparatus hitherto employed, upon the will or knowledge of the patient.
Figures 1 and 2 of the drawing show an apparatus embodying the invention in front elevation partly in section and in side elevation. Figs. 3 to 5 illustrate various constructional forms of the detail devices.
T he construction illustrated in Fig. 1 consists broadly of a two-cylinder pump the cylinders p, q of which communicate on their upper side with the atmosphere while each lower side is provided with a suction and delivery valve (20, 21 or 22, 23) or valve of any other suitable types. The suc- :ion valve 21 of the cylinder and the delivery valve 22 of the cylinder q open into'the atmosphere while rigid conduits 3, 5 connect with the two valves 20 and 23 of the two cylinders 70 47," these rigid conduits are connected by flexible conduits 2, l with the two connections on n of a mouthpiece 0. A suction valve 8 opening toward the mouthpiece cavity is arranged in the scolifit to while a delivery valve 12 closing toward the mouthpiece cavity is arranged in the suction socket n. The connection of this monthpiece 0 with the pump is therefore established in such a manner that the delivery conduits 3, 2 of the cylinder 77 is connected with the socket m containing the suction valve 8 while the suction conduit 5, 4:- of the cylinder 9 is connected with the socket n of the mouthpiece 0, which contains the delivery valve d. If the mouthpiece o is arranged on the mouth and the pistons of the cylinders p, g raised and lowered in correspondence with the phases of the respiration, when the pistons '12, w descend, the air which on the former stroke has been drawn through the valve 21 into the cylinder 72 is discharged through the conduit 2, 3 into the mouthpiece and the cavity of the mouth while the air contained in the second cylinder 5 is discharged through the valve 22.
When the two pistons 12, to ascend the cylinder ;0 is filled with fresh air through the valve 21 while the second cylinder q sucks the air out of the mouthpiece o and the mouth cavity. By the uniform movement of the pistons p 9 therefore, air is alternately forced into the mouth cavity and extracted therefrom.
In order to adapt the quantity of air supplied and extracted at each .phase of the respiration to the individual requirements of-the patient the stroke of the pistons 12 10 can be modified. With this object a crank pin 72, is displaceably arranged in a radial slot 11 of the crank plate I) and is adapted to be clamped in any position that may be given to it. In order that it may be possible when altering the strokes in this manner to shift the lower reversing position of the pistons a) w back to the lower ends of the cylinders again, the connecting rod a is adjustable to various lengths. With this object it consists of two relatively sliding parts held in any given position by two nuts 10, 10 mounted in one of the parts and which engage through a longitudinal slot 12 in the second part (Fig. 2).
in order to permit of varying the number of the respirations, that is to say, the number of revolutions of the pumps, the plan is adopted of throwing the connections with the pumps oii the motor T, which runs at a constant speed, by the intermediary of two cone pulleys f, g which permit of all speed ratios necessitated by the minimum and maximum number of respirations.
In order that the respiration process, that is to say, the injection and extraction of the air may be eflected intermittently; obturating members are interposed on one or both the air supply and suction are obtained by rotary cocks i, 71 inserted in the conduits 3, 5 and caused to rock by a rack b by the intermediary of suitable transmissions 7, 6, 6, this rack being fixed to the cross piece at of the two pistons rods; In order to obtain quickly succeeding interruptions the obturating cocks i can be operated by the armature 13 of an electro magnet 14 as shown in Fig. 3; the circuit of this magnet is interrupted by displacing the armature 13 in the known manner.
As shown in Fig. 4 any appropriate device 15 of a known kind can be arran ed in the conduit 2 serving for supplying t e inhalation air; this device impregnates the air with medicinal substances in the form of powder or vapor or ozonizes it; the same purpose can be served by arranging a device 15 of this kind in front of the suction aperture 21 of the cylinder p.
In the construction illustrated in Fig. 5 the socket containing the suction valve 21 does not open into the atmosphere but is fitted to an oxygen reservoir k; the pressure reducing valve j interposed between the cylinder 37 and the oxygen reservoir is and the mixing nozzle 2 can be adjusted in accordance with the prescription in such a manner that the air drawn in by the cylinthat the supply of inhalation air is given intermittently.
It will of course be understood that the pumps might be replaced by any other suitable devices such for example as bellows.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
An apparatus for inhalation purposes comprising two pumps, suction and delivery conduits attached to said pumps respectively a single crank drivin said pumps and alternately exerting a b owing and a suction efiect on the respiratory passages, a slot in said crank and a crank pin displaceably arranged in said slot and adjustable to various positions therein,- and means for automatically interrupting the suction and blowing efiect in a rythmical manner, as specified. I
In testimony whereof I aifix my in the presenceof two witnesses.
