UNITED STATES PATENT OFFICE.
AUGUST V. ILPIH LGREN, OF MILVAUKEE, WISCONSIN.
COMBINED STETHOSCOPE. AND PNEUMOSCOPE.
SPECIFICATION 'iorming part of Letters Patent No. 268,430, dated December 5,1882.
Application filed May 6, 1882. (No model.)
To all whom it may concern:
Be it known that I, AUGUST \V. It. PIHL- GREN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in a Combined btethoscope and Pneumoseope, of which the following is a full, clear, and exact description, which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to the construction of an instrument that may be used separately as a stethoscope, or as a stethoscope and pneumoscope combined, and also as either a single or double stethoscope.
The invention consists in the combination and arrangement of a tube having a mouthpiece or an ear-piece at one end, secured to a tube of a larger diameter at the other, the opposite end ct said larger tube being provided with a suitable bell or cup piece of such a shape as to be conveniently placed in or over the mouth of the person operated upon, and having a damper-shaped valve to regulate the breathing, and also in having fixed to its under part a whistle and mirror, all serving the purpose of enabling the operator to listen to the breathing of or testing the lungs, orjudging of the action of the heart, also of forcing air into the lungs, and when it is impossible to detect respiration otherwise, it is indicated on this instrument by the whistle or on the mirror, as hereinafter more particularly described.
In the accompanying drawings, which illustrate my invention, Figure 1 is a longitudinal central section. Fig. 2 is a face view of the ear-piece. Fig. 3 is a sectional view of the cap or cover of the whistle.
Similar letters of reference indicate corre sponding parts.
F is a tube of rubber or other flexible mate rial, having screwed on its outer end a flaring or bell-shaped mouth-piece, G, which is to be placed in the mouth of the operator. The other end of the tube F is attached to a piece of hard wood,J, which is provided with screw threads for fastening it to the outer end of the large tube A.
The large tube A may be made of wood,
metal, or other similar material; but I prefer to make it of hard wood and of any desirable shape and size.
To the inner end of the tubeA is attached a piece of hard wood, (I, which serves to join the hell or cup-piece G to the tube. The tube Ais provided on its under side with asuitable opening, P, into which is secured a nipple, D, having arranged in it a delicately-constructed whistle, K, somewhat like the whistles used in rubber dolls, and which is adapted to receive a cap or cover, I, when the whistle is not required-as, for example, when the instrument is to be used as a stethoscope.
Extending downward from and near each side of the opening 1?, and screwed to the tube A, are two metallic rods or arms L L, to the ends of which is pivoted a revolving mirror, E, provided with a wooden or other back, so that when it is not necessary to use the mirror, its back may be presented to the opening Pin the tube A. The tube Ais also provided with a damper or valve, B, made of suitable material, and it may be provided on its periphery with a rubber rim to make it fit snugly and closely, so that it will form an air-tight conneetion when the damper or valve is turned across the tube. The damper or valve B is secured to a rod, 6, which has bearings in the tube, and on one end of which is formed a handle, 0, preferably T-shaped, which will also serve as a gage to indicate that the damper or valve B is opened or closed, thereby obviating the necessity of trying the instrument by the operator each time it is to be used.
H isacircularear- 'iiece, constructed of wood, metal, rubber, or any other desired material, and provided with anope1iing,i,having screwthreads.
When it is desirable to form thestethoscope, the mouth-piece is removed from the tube F and the ear-piece placed thereon, so that the ear-piece can be conveniently held near the ear of the operator.
The oval bell or cup-piece C may be constructed of rubber, and of anydesired size, and attached to a piece of wood,d, or otherwise, to make it air-tight when joined to the tube A.
VVhenit is desired to form and use the pneumoscope the mouth-piece G is first placed on LOU the tube F. The operator. then opens the damper or valve B by means of the handle 0, and having properly adjusted the revolving mirror E to the position shown in Fig.1, places the mouth-piece O in or over the mouth of the person to be operated upon, and the mouthpiece G in the operators own mouth. The operator then blows through the mouth-piece G in the direction of arrows in tubes F A, and then at once closes the damper or valve B, and if there is any indications of breathing the air will return and take the course indicated by the arrows, down through the nipple D, and be indicated by the whistle or by moisture on the mirror E.
My invention is useful for testing the condition of persons who have been suffocated by gas or otherwise, children just born, those in asphyxia, for atelectasis in children, those that have been in the water or drowned, &c., as may be required.
I do not confine myself to any special material in constructing my improved stethoscope and pncumoscope. If desired, the tubes F A, the nipple D, and the oval hell or cup-piece 0 may be molded in one piece from glass or rubber.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A flexible tube, F, having a suitable end piece, in combination with a largetube, A, having a nipple, D, formed on or attached to its under side, which is provided with a removable cap or cover, I, and an oval-shaped hell or cup-piece, O, substantially as and for the purpose set forth.
2. A tube, A, having a detachable hell or cup-piece, O, nipple D, with a whistle, K, arranged therein, arms L, secured to the under side of said tube A, to the ends of which is pivoted a revolving mirror, E, in combination with a damper,B, secured to a rod,c, and having a handle, 0, substantially as and for the purpose specified.
3. Atube, F, provided with asuitablemouthpiece, G, in combination with a large tube, A, provided with a damper or valve,B, and abell or cup-piece, O, and having a nipple, D, which has a whistle, K, arranged therein, and a removable cap or cover, I, and a revolving mirror, E, attached to the tube A by means of arms h, substantially as and for the purpose specified.
4. A tube, F, having'a suitable end piece attached at its opposite end to a larger tube, A, by means of a connecting-piece, J. in combination with said tube, A, having a bell or cup piece, 0, attached thereto by means of a connecting-piece, d, and having on its under side a nipple, D, with a whistle, K, arranged therein, said nipple being provided with a removable cap or cover, I, a damper or valve, B, secured to a rod, 0, and having a handle, 0, and a revolving mirror, E, attached to tube A by means of arms L, being so arranged that the face of the mirror is adapted'to be brought directly under and opposite the opening in the nipple D, substantially as and for the purpose set forth.
