INSTRUMENT FOR ADMINISTERING .ANES'IHETICS.
To all wliom it may concern:
Be it known that I, FLOYD B. JONES, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have' invented certain new and useful, Improvements in Instruments for Administering Anesthetics, of which the following is a specification.
My invention comprises a new and useful instrument for anesthesia or. analgesiav administration, particularly in nose, mouth, throat or dental operative work, and the instrument is particularly constructed to give the operator a free field for his work which is impossible with other instruments now in use, and is also particularly constructed to be held and controlled by the patient so that the anesthetic or analgesic gas or gases may be cut off at any time or the administration of same continued by him as he may determine or require. ,One of the principal virtues of the appliance is that a patient will freely consent to its use as confidence is instilled in him from the fact that he has it under his'own control at all times, whereas in strapping the ordinary appliance in a fixed place over the nose and. around the head invariably causes a patient to have a feeling of uncertainty and misgivingin short a lack of confidence attended by more In the accompanying drawings, Figure 1 is a perspective view of the invention in use, and Fig. 2 is a perspective view of a modified form of the invention. Fig. 3 is a front view and section of the instrument, and Fig. 4 is a side elevation and longitudinal section of Fig. 3. Fi 5 is a front elevation of the plunger vaFve and hand piece without the extension tubes.
The invention comprises a tubular handhold member 2 having a cross cylinder 3 in which a plunger valve 4 has a limited movement under the pressure of a coiled spring 5. A set screw 6 is provided in the end of Specification of Letters Patent.
Application filed April 14, 1913. Serial No. 761,057. a
cylinder 3 to change the tension of the sprlng, and a thumb screw 7 projected through slot 8 in the side of cylinder 3 (Fig. i 5) limits the outward movement of the valve and also provides a. means for locking the valve in any desired position. Valve l'is hollow and has-a passage 9 in its side adapted to register with the intake tube 10 of member 2, and also an opening 11 oppos te passage 9 to register with the discharge tube 12. Passage 9 is offset sufliciently in respect to opening 11 so that it Will be closed by the wall of cylinder 3 when the valve is pressed outward to its limit by spring5, but'opening 11 remains in constant register with the discharge tube 12 A slot 14 near the end of valve 4 perm1ts air to enter the -discharge tube 12 when valve 4 is in its normal position with passage 9 closed, Fig. 3. However, when the valve is pressed inward by the thumb, see Flg. 1, the air intake slot 14 is .closed and the gas is free to pass through the tubular member and out of'the two spreading extension tubes 15'having the nasal plugs 16. Tubes 15 are rigidly united with a knurled cap .17 which is removably and rotatably sleeved over the end of discharge tube 12, and the said tubes branch outwardly and upwardly and then toward each other at their outer ends so that the instrument may rest longitudinally on the chest of the patient with the extension tubes spanning the face in a retired position relatively to the mouth of the patient. The operator is thus enabled to work in .the mouth or throat without the slightest interference and his view is also unobstructed, and as the nasal plugs 16 are held inrtheir place by the patient pressing upward on the instrument no inconvenience is suffered by him. Moreover, the metal tubes 15 .yield and spring readily in different directions to give a comfortable fit, and the plugs 16 are also rotatably secured to the ends of the tubes 15 to. provide an accommodating movement between these parts to enable the patient to change his position in the chair, either vhead or body, without any loss of comfort to himselfor displacement of the plugs. As shown, these plugs are removably slee ed upon the short elbows 18 to permit them to be cleaned and sterilized and to permit other sizes or kinds to be substituted therefor. The elbows 18 are also removably mounted upon the ends of tubes 15, one
mode of doing this being as shown by a split elbow to spring-engage the beaded ends 19 of the tubes 15. A separate elbow or equivalent member to support the plugs 18 is not absolutely essential, but is the preferred way in lieu of mounting them on the ends of the tubes 15 direct, especially in view of the advantages as described. Va-
rious mouth or nasal attachments may be.
used in lieu of the plugs, or the construction shown may be variously modified Without departing from the spirit and scope of the invention. To illustrate the use of a substitute appliance to cover the nose or mouth, see Fig. 2, wherein a small hood 20 is shown as attached to the ends of the tubes 15 and by means of which the gas is administered. This device is provided with separate valved inhalation and exhalation. passages 21 and 22, respectively, such as shown in member 2, Fig.4. The inhalation passage is for member 2 respresented by an openlng 23 in a cap 24 which covers a thin aluminum disk valve 25 normally held by gravity upon, the grid portion 26 of the branch tube 27, and the exhalation passage is represented by the small openings 28 in the thimble-29 which is sleeved over the other branch tube 30 to house the thin disk valve 31 which is normally held closed by a light spring 32, the thumb screw 33 serving as an adjustable stop for the valve.
In operating the instrument the patient holds the same in either hand, with the valve plunger under his thumb. It will be noted that member 2 can be rotated in respect to tubes 15 so that a comfortable hand grip can be obtained without disturbing a fixed position oftubes 15. Now for analgesic work the anesthetizing mixture is administered by the patient pressing down on the plunger valve. Should he feel that he desires more air with the anesthetizing mixture he -releases the plunger and 'more or less air is admitted at slot 14. On the other hand should he feel' that he is losing consciousness he can, by re:
leasing plunger valve, shut ofl the mixture entirely and admit free air. The device cuts ofi the gas automatically when the patient is losing consciousness, as he relaxes enough "to allow the spring behind the valve to ress.
the valve outward, thereby also admitting a free supply of air.
If the apparatus is to be used to induce anesthesia, the*valve can be held open by means of the adjustable 'set screw 7 and the control is then entirely in the hands of the operator.
One advantage of the instrument is that of economy in use as none of the anesthetizing or analgesic mixture is lostin opening or closing valve 4. Furthermore, by using applicators of plug form at the terminals of arched discharge tubes, the upper lip of thepatient is uncovered and free to be lifted at all points. In brief, the construction and operation of the device is simple and easily understood and as the application and control is in the hands of the patient these factors appeal to apatient, as a complicated device naturally produces a negative suggestion,a feeling of confusion and distrust. Again, when the patient experiences the automatic workings of the instrument, full confidence is given and the patient quickly induces'an analgesia condition which materially aids the operator in his work.
What I claim is:
1. An instrument for administering fluids or vapors, comprising a valved member adapted to be held and controlled by the individual under treatment, said member having a rigid forked tubular extension with inwardly turned ends for local application of the fluid at the head of the individual. 2. An appliance. for anesthesia or analgesia administration, comprising a self-closing valve adapted to be held in the hand and relatively long discharge tubes leading therefrom having rigid arched extremities to span the face.
3. A gas and air administering device, comprising a tubular member having an intake portion to connect with a source of gas supply and provided with a self-closing valve, and tubular discharge extensions branching outwardly and upwardly and inwardly and having detachable and rotatable connection with said member.
4. In an instrument of the kind described, a tubular body having a valve to control the flow of fluid therethrough, tubular discharge extensions for said body having arched extremities branching laterally in opposite directions and thence at substantially right 05 angles thereto on curved lines and again laterally toward each other substantially as shown, and applicator members for said extremities.
5. In an instrument for administering anesthetics, a tubular body having a valve, and
a set of diverging and arching discharge valve in different fixed-positions, and applicator discharge members extending from said body.
-7. In an instrument for administering anesthetics, a tubular body having a pluiiger valve provided with separate passages and a spring for said valve to normally keep one of the passages closed and the other open, a device to-lock the valve in a set position, a
set of discharge tubes extending from said body, terminal appliances for saidtubes, 12a
and a set of inhalation and exhalation valves for the instrument.
8. In in instrument for administering anesthetics, a tubular body having a cross cylinder, a plunger valve and spring therefor mounted in said cylinder, separate gas and air intake openings for said valve and a common discharge passage for said gas and air, means to lock said valve in a set position, inhalation and exhalation valves in communication with said discharge passage, and a set of bifurcated discharge tubes having nasal plugs attheir extremities.
9. In an instrument of the kind described, a supply connection having a valve transversely thereof provided with a plurality of ports and a spring to close the same, and a bifurcated discharge connection having upwardly and inwardly curved extremities and applicators to localize the discharge products and forming a movable part thereof.
10. In an instrument for administering air and gas, a. tubular supply connection having a tubular transverse barrel, a tubular valve in said barrel to control both the air and gas having separate air and gas ports and diverging discharge tubes having arched ends projected divergently and then inwardly and provided with applicator members.
In testimony whereof I alfix my signature in presence of two witnesses.
