PULMOTOR.

mavens.

Application filed June 15. 1915.

T 0 all whom it may concern:

Be it known that I, Jcmarr H. Pnnarox'r, a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have invented a new and useful Pulmotor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved pulmotor, particularly adapted for resuscitating persons from which life is supposedly extinct.

One of the objects of the invention is to provide means for injecting intermittent supplies of oxygen or oxygenated air into an apparently dead body, or corpse, to re suscitate the body, or for restoring life.

Another object of the invention is to pro-- vide a means consisting of a spring ten sioned valve, for controlling the oxygen or oxygenated air, as it is intermittently discharged into the air passages.

A further object of the invention is to provide means to prevent the valve from binding during its intermittent action.

Another object of the invention is the pulmotor including be applied or injected into a body, wherein there is still suiiicient heart action and the lungs are relieved of substantially all air or oxygen, without utilizing the stored oxygen or oxygenated air of the apparatus This is accomplished by an extra tube connection with the valve casing above the valve therein, and through the tube from the valve casing to the face mask or hood, which fits over the nose and mouth.

Another object of the invention is to provide means for holding thevalve raised sufficiently, whereby a combined steady supply of stored oxygen or oxygenated air may be injected through the tube connection between the valve casing and the face mask or hood, especially in cases, where life has been extinct fora considerable time, apparently beyond resuscitating. Very often a device of this nature is utilized for keeping life, or extending life of a dying person.

Specification of Letters Patent.

lPatentediillar. 28, min. Serial No. 34,212.

Another object of the invention is to provide means for forcing or injecting the oxygen or oxygenated air into the body, and yet at the same time permit the operator or physician to have free use of his hands and arms, so that while forcing or injecting the oxygen into the body, the operator is at liberty to work the arms and hands of the body. applying artificial respiration in ad dition to the injection of oxygen or oxygenated air.

Another object of the invention is to provide a sleeve having apneumatic means for siphcning or forcing the oxygen through the apparatus by compression. This sleeve is adapted to be worn upon the arm of the operator with a pneumatic means adjacent to or between the body of the operator and his arm.

Another object of the invention is to provide an auxiliary device, consisting of a bellows, to wh1ch the apparatus or pulmo- ,tor may be attached, whereby the exhausted the valve casing merely being held by theoperator for the purpose of illustration, not through necessity. Fig. 2 is an enlarged sectional view through the various parts of the pulmotor. Fig. 3 is a sectional view through the valve casing and the adjacent attending parts, showing the valve partially raised, so that the oxygen will pass through the tube connection between the valve casing and the face mask or hood. Fig. 4 is a view in side elevation of the valve casing. Fig. 5 is a sectional view on line 55 of 3. Fig. 6 is an enlarged detail view of the auxiliary bellows.

Mounted in the valve casino; 1'? is a valve 27 provided with a stem 28 which is supplied with a disk 29, Whiclrnot only constitutes an abutment for the spring 30 the disk 29 and the top or closure 31 oil the valve easing) but also acts as an auxiliary guide for the valve rod and valve, forthe reason that said disk 29 slides in the casing. sure or top 31 (which is threaded at 32 to the casing 17) is provided With a series of apertures 33, which allows air to enter the valve casing above the disk 29, during; the actuation otthe valve 27, to prevent the valve from binding du *ing its movements.

The valve rod 28 passes through and is guided in an opening 34 of the closure or top of the casing" 17 and adjoining the open- 3d are two radially disposed openings or slots 35. Carried by the rod 28 is log 36, of suthcient as to pass thrinwa the passage ill of the tube 19 so that the h A suitable tube 5 eon- The radial openings or slots For instance, the valve 2! may be raised sutnciently above will pass through one or the other of t slots or openings 35, after which the rod 28 s given partial turn, thereby support inn; the valve in a raised position. The valve 27 normallyrests upon the shoulder il, and when in such a position an operator ol' the apparatus may blow through the tube 39,

Without aotuatingrthe pneumatic device 9, This is accomplished inslight eases, merely artificial respiration is needed.

The bellows 4:8 is provided with suitable hooks or devices 4:5, to engage the clothing of the operator, thatis, the sleeve and one side of the center other Wearing apparel between the arm at any suitable location adjacent the elbow-joint and the body of the operator, whereby considerable force may be utilized, for operating the bellows. in lieu of thehooks a5 a suitable elastic strap l? having an adjustable buckle may be applied to-the bellows as shown in. Fig. 6, so that the same may he strapped to the arm in a secure and firm position adjacent the elbow joint, whereby the arm of the operator may he brought away from the body with considerable force, in order to suck stagnant air from the lungs.

The various flexible tube connections may be provided With suitable silk armor, as

shovvn'at 48 in Fig. 1. In the ordinary cases of resuseitating persons, the pneumatic de vice 9 which has been filled with oxygen or oxygenated air is operated by thearm of the operator, pressing agalnst the operator s side thus -forcing air through the extension tube 10 and the tube'15. The bag 9 is unused.-

I ately refilled with gas under pressure from No. l and the operation 18 repeated every three to four seconds, the valve 27 being intermittently raised and allowing the oxygen to pass through the tubes 19 and 20 into the face mask 1 hood, Where it enters the nose cases is propped of the person, which in such open by a suitable gag. as indicated at in Fig. 1. in very simple cases the operator may merely blow through the tube 39, which Will pass through the valve casing through the tubes 19 and 20 into the lace niaslt for respiration.

improved pulinotor, the mask or hood 2 L is first fitted over the of the, patient, "While the valve easing ll is held in one hand, Whereas the large bulb or bag! 9 is held by a sleeve on the other arm, and the container or reservoir for the oxygen is suspended from the neck of the operator or physicion by a suitable strap. in the supplying" artificial When using: this method shown in Fig; l, the mouth piece t0 the mouth of the having; depressed may be then placed in operator. The operator the large bulb or bag, whim is between the Where stagnant air from the arm and the body, the bulb or bag is allowed to expand thereby sucking or drawing oxygen from the reservoir or container into the bulb. The bulb 9 is then depressed, thereby forcing the oxygen through the tube 15, raising the valve 27 above the point or j unc tion 18, in which case the oxygen passes through the tube 19 into the mask or hood, here it enters the patient through the mouth, which is propped open by a suitable gag. Just so soon as the pressure is relieved on the bulb or bag 9, pressure is relieved on the valve 27, and owing to the tension of the spring 30, the valve-27 becomes seated. It

is to be observed that as the bag or bulb 9 expands another supply of oxygen is drawn into the bag or bulb. After the valve 27 becomes seated, the operator may exert a suction force through the tube 39, and the tube 38 (which isain communication with the tubes 19 and 20, that is, when the valve 27 is seated) thereby drawing or sucking the lungs of the patient. The mouthpiece 40 of the tube 39 may be temporarily removed, and then pressure may be applied upon the bag or bulb 9, raising the valve 27, and forcing another supply of oxygen into the body of the patient, after which the valve 27 is allowed to seat again. The mouth piece 40 is again inserted in the mouth of the operatorso as to create a suction force as before stated. These operations may be consecutively repeated, until the patient has become resuscitated. If desired, when not using the bulb 9 or the oxygen in the container or reservoir, and in very slight cases, the physician or operator may alternately blow and suck through the tube 39 and the tubes 19 and 20, by placing the mouth piece 40 in the mouth, that is, of the operator. In very extreme cases, the physician or operator may find 1t inconvenient to suck or draw through the tubes 39, 19 and 20, in order to draw out the stagnant air from the lungs. Therefore, as heretofore set forth in the statements of the invention, a bellows is provided, in which case the mouth piece 40 may be detached from the tube 39. in which case the tube 39 may be connected to the extension tube 44 of the bellows l3 as shown in Fig. 6. After attaching the bellows to the tube 39 in this manner, and just immediately after having raised the valve 27 (due to the pressure of oxygen thereon) the bellows (which may be connected to one of the arms of the operator by the means 47) is de pressed. When the benows is depressed its check valv 43 opens outwardly, thereby permitting the escape of air or stagnant oxygen from the bellows. The bellows is held depressed as long as the valve 27 is held raised. However, as soon as the valve seats. the bellows is allowed to expand, thereby creating suiiicient suction through the tubes 39, 38, 19, and 20, to draw the stagnant air from the lungs into the bellows. Immediately following this operation the bulb or bag 9 is depressed forcing oxygen against the valve 27, raising it above the junction 18, and allowing the oxygen to pass through the tube 19 to the mask, and cutting otl communication between the tube 1%) and the tube 39. Subsequently to the cutting off of the communication the bellows is depressed, allowing the escape of the stagnant air from the bellows. These operations, when using the bellows in this manner ar alternately repeated, until the patient has become resuscitated.
