SPECIFICATION forming part of Letters Patent No. d43,191, dated December 23, 1890.
Application filed August 23, 1890- Serial No. 362,857. (No model.)
To all whom it may concern:
Be it known that I, KARL ILLING, a subject of the King of Saxony, residing at the town of Zwickau, in the Kingdom of Saxony, in the German Empire, have invented certain new and useful Improvements in or relating to Inhalers, of which the following is a specification.
The main object of this invention is to enable invalids suffering from disorders in the respiratory organs to inhale fresh air warmed to the desired temperature; but the invention is also adapted to permit persons in good health to remain without danger in places where the air is vitiated.
Many of the inhaling apparatus hitherto known under various names-such as respiraters and breathing-masks, &c.l1ave this defect in common, that they admit pure air through the same channel or medium through which the exhalations issue, so that the supply of air becomes invariably impure before it reaches the mouth.
In the device herein described the two channels or ways are independent of each other, their respective openings being closed by diaphragms or membranes, one of which closes while the other is opened. The air to be inhaled is notsupplied from a point immediately adjoining the mouth of the invalid, but from a source which may be situated at any desired distance, and before it reaches the respiratory organs it is purified, warmed, and, if necessary, saturated with some agent possessing curative or other properties.
In the accompanying drawings, Figure 1 is a sectional elevation of the complete inhaler; Fig. 2, a horizontal section of the reservoir; Fig. 3, 'a vertical section of the cup or mouthpiece; and Figs. 4 and 5 are vertical sections of the inlet and outlet valves, respectively, when open.
The before-mentioned result in the apparatus shown in the accompanying drawings is accomplished by means of a reservoir or chamber A, divided into several compart ments and constructed of metal, india-rubber, card-board, or the like.
The division of the reservoir into compartments is effected by means of partitions A A one end of each of which is bent laterally, as shown. The bent end of the partition A is secured to the reservoir to the right of the air-inlet opening, and the bent end of the partition A is secured to the reservoir to the left of the air outlet opening, whereby the air is caused to partake of the course indicated by the arrows in Fig. 1 in its passage through the reservoir. The air to be inhaled is sup plied to the first compartment a by means of a flexible tube?) of any suitable length. This first compartment may be filled with cottonwool soaked with glycerine for the purpose of filtering the airand intercepting dust or other impurities. From this part the air passes through the serpentine or sinuous passages into the second compartment a filled with cotton-wool, which may be impregnated with medicine or the like wherewith it is desired to saturate the air to a greater or less degree. From this compartment the air is inhaled by the user through another flexible tube 1). The reservoir A being attached to the body, preferably the chest of the invalid, the air as it slowly passes along the serpentine-shaped passages is warmed nearly to the blood temperature.
The end of the flexible tube 1) is provided with a cup d, adapted to be applied to the mouth of the invalid and surmounted with two tubes 0 c, intended to close the nostrils against the external atmosphere. The cup cl is further provided with two openings 6 6, covered with gauze or the like. Over these openings or sieves are arranged the membranes, diaphragms, or valve f f of thin in dia-rubber, fish-bladder, gut, or the like, retained in position over the centers of the sieves or openings by means of springs g g The diaphragm f, covering the air-inlet, is situated over the sieve e, while the diaphragm f which closes the air-outlet, is arranged behind the sieve 6 within a perforated. case it.
From the foregoing it will easily be gathered how this inhaling apparatus is used. lVhen air is inhaled, the membrane f laterally recedes from the sieve or inlet e, as in Fig. at, while at the same time the membrane f is pressed by the external air against the sieve e, as in Fig. 3, thus effecting an airtight closing of the outlet. lVhen the air is exhaled, the reverse takes p1ace-that is, the membrane f is closely pressed onto its sieve c, as in Fig. 3, and the membrane f laterally ICO moves away from the sieve e, as in Fig. 5, so that the air exhaled may escape through the sieve e and perforated case 72 The mouth-piece (Z I prefer to removabiy secure to the tube 1), and for this purpose it is provided with a short section of tubing (1 over the inlet-opening and having a bayonetslot (Z into which projects a pin or stud (l on the tube b. (See Fig. 1.)
I claim- 1. In a device of the character described, the combination, with the reservoir having air-inlet and air-outlet openings therein, of.
the partitions A A having .the laterallybent portions, one of said partitions being so cured at one side of the air-inlet opening and the other at the side of the air-outlet opening opposite to that at Which the first partition is secured, whereby the air is caused to take the serpentine course through the reservoir described.
2. Ina device of the character described,
the combination, with the month piece adapted to fitover the mouth of aperson and provided with air-inlet and air-outlet openings e e and a tube communicating with the inlet-opening, of the perforated diaphragms arranged over the said openings, the valve f, arranged over and against the inner side of the diaphragm of the inlet opening, the vaivef, arranged over and against the outer side. of the diaphragm of the outlet-opening, and the tube 0, secured to the upper portion of the mouth-piece, adapted to enter the nos- .triis of a person, and communicating with the interior of the mouth-piece, as described.
In testimony thereof I have hereto set my hand in the presence of two subscribing witnesses.
