GEORGE G. CARROLL, OF ROCHESTER, NEW YORK, ASSIGNOR TO ELECTRO SURGICAL INSTRUMENT COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.
. MYRINGOSCOPE.
Specification of Letters Patent.
Patented Aug. 111, 1914.
To all whom it may concern Be it known that I, GEORGE G. CARROLL, of Rochester, in the county of Monroe and State of New, York, have invented certain new and useful Improvements in Myringoscopes; and I do hereby declare the following to be a full, clear, and exact descriptlon of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.
My, invention relates to myringoscopes, for making examinations of the ear, and it has for its object to provide a structure which enables the person making the examination to take a position in front of the patient and to cause movement of the ear drum either from the interior or exterior while at the same time observing the eifect by watching and simultaneously listening to the excursions of the drum.
To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.
In the drawings: Figure 1 is a view in elevation of a device arranged for attach ment to the head, and adapted to be connected to the ear, showing a preferred embodiment of my invention; Fig. 2 is a sectional view on the line -.22 of Fig. 1, showing the speculum removed, and Fig. 3 is a horizontal sectional view on the line -3* of Fig. 1. Similar reference numerals throughout the several figures indicate the same parts.
In the present embodiment, 1 designates a hollow, preferably cylindrical body portion having a closure 2 at one end and open at its opposite end to receive a removable speculum 3, which is adapted to engage the opening in the ear, as usual in this class of devices. At its opposite end, the body portion is provided with a mirror or other reflecting element designated at 4 which is preferably arranged on the post 5 secured to the closure 2. The body portion is formed at one side with an opening 6 which is surrounded by a flange 7 having pins 8. The 0 ening 6 is a sight opening in line with the mirror or reflecting element 4, and may be provided with a lens 9 secured in a holder 10 which is provided with the slots 11, forming a bayonet joint, and cooperating with the pins 8 to retain the lens in position. With this arrangement, it will be seen that a person can stand in front of the patient and be treating him through the nose or mouth, while at the same' time observing the effects upon the ear drum through the sight opening 6, which is disposed at right angles to the longitudinal axis of the body portion.
In order to illuminate the drum of the car, while the speculum is inserted, I provide an incandescent lamp 11 which is arranged in such a position as to direct the light toward the small end of the speculum. For this purpose, I preferably support the lamp in a nipple or socket 12 which is arranged in a suitable opening in one side of the body portion and is in threaded engagement with a tube 13 disposed exteriorly of the body portion, and through which the wires of the circuit lead in any suitable manner. The closure 2 is provided with an opening having a nipple 14 formed on the outside thereof, adapted to receive a removable connection 15, the latter being engaged by a flexible tube 16 which may carry a bulb' at its opposite end.. By this means, air pressure may be supplied to the ear drum through the speculum, and the effect of such pressure upon the drum can be determined by watching the excursions of the drum through the lens 9. In some cases, it is desirable to also .listen to the movements of the drum while pressure is applied, and for this purpose I may provide the free end of the tube 16 with a connection that may be applied to the ear of the person conducting the examination, while at the same time he may apply pressure internally to the drum through the eustachian tube by the catheter such as usually employed for this purpose.
The important features of advantage of my present device are that it enables one to make a visible and audible examination of the ear drum at the same time, while occupying a position before the patient, and to effect movement of the ear drum by pressure applied either to the inside or the outside as may be preferable. This has never been possible to accomplish with any of the devices now in use. In order to hold the instrument in proper position on the head of the patient, I provide a flexible band consisting of sheet metal sections 17, 18 and 19, arranged in slidable relation to each other as shown. The section 17 carries a handle 20, while the section 19 carries a post 21 provided at its outer end with a ball 22. 23 is a swiveled ring which is in frictional engagement with the body portion and carries an arm having at its outer end a ball 24. 25 is a clamp having suitable sockets cooperating with the balls 22 and 24, and provided with a thumb screw 26 by which the clamp may be tightened.
I claim'as my invention:
1. In a myringoscope, the combination with a hollow body portion having a speculum at one end, of a reflector arranged at the opposite end of the body portion at an angle to its longitudinal axis,- and an incandescent lamp arranged within the bod portion to direct light into the speculum, t e body ortion having an opening in one side, at a right angle to its longitudinal axis to aflord a view of the reflector. Y
2. In" a myringoscope, the combination with a hollow body portion having a speculum at one end, of a reflector adjacent to the opposite end arranged at an angle to the longitudinal axis of the body pprt-ion, an incandescent lamp within the body for directmg light into the speculum, the end of the body portion adjacent to the reflector having an opening therein, and a tube connected to said opening, one side of the body portion having an opening formed at right angles to its longitudinal axis to afford a view of the reflector.
GEORGE G. CARROLL.
