G. F. JACKSON ET AL SURGICAL AND DENTAL APPLIANCE mm ummm INVENTOR ATTORNEY Patented Nev. 2341i, i925.
UNITED STATES PATENT OFFICE.
GEORGE FRANKLIN JACKSON AND FRED EARNEST CAMPBELL, OF LITTLE ROCK,
ARKANSAS.
SURGICAL AND DENTAL APPLIANCE.V
Application filed May 15, 1925. Serial No, 30,582.
To all whom t may' concern:
Be it known that we, GEORGE F. JACKSON and FRED E. CAMPBELL, citizens of the United States, residing at Little Rock, in
the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Surgical and Dental Appliances, of which the following is a specitication.
The invention relates to the arts of surgery and dentistry and it particularly has for its object to provide an appliance for use in taking up liquids and moisture `in surgical and dental operations.
It primarily has'or its object to provide a simple, inexpensive appliance by means of which and by the use of compressed air as the motive Huid, a partial vacuum may be produced in a bottle or vessel, into which the fluids to be taken up are drawn by the suction of the partial vacuum within the bottle.
ln general the invention provides a bottle or vessel with a removable cap, a cap sus- 35 tained inlet duct for compressed air and an exhaust duet through which air from the vessel is evacuated, the inlet duct having attached thereto a nozzle with a small discharge orifice directed into the mouth oit' the exhaust duct to serve as an ejector, the compressed air stream causing the air within the bottle to be ejected through the exhaust duct until the desired degree of vacuum within. the vessel is obtained; the cap also carries a thirdy duct of smaller area than the others, through which the fluids are sucked into thc bottle, via a flexible pipe attached thereto and leading to the place where the fluids are to be gathered or taken up.
In its more specific nature the invention resides in those novel constructions, combinations and arrangements of parts, which will first be fully described and then be specifically pointed out in the appended claim. reference being had to the accompanying drawing, in which :w l
Figure 1 is a side elevation oi my invention.
Figure 2 is an enlarged detail vertical longitudinal section of the same showing one means of securing the cap to the vessel vin a removable manner.
Figure 3 is a view similar to Figure 2 showing another means of holding the cap on the vessel detachably.
In the drawing in which like numerals 'ot reference indicate like parts in all the ligures, 1 represents the bottle or vessel which maybe made of glass or other suitable material, and 3 indicates the cap which may be removably mounted on the vessel by threading the cap and vessel together as at 2 or by means of spring clips 2". A suitable rubber packing ring 4 may be provided to keep the air sealed.
The cap carries the various ducts employed and as will be clear from Figures 2 and 3 of the drawing it will be noted that 5 designates a duet for delivering compressed air through the cap into the vessel, the duct 6 having attached thereto at 9 a nozzle 8 whose orifice 10 delivers the compressed air into the ared mouth 7 of the exhaust duct 6.
11 designates the suction duct whiclris carried by the cap and has a nipple 12 to which the iexible hose 13 that leads to the place where the iiuids are to be gathered up, is connected.
In the practical application of our invention a system of piping compressed air is conducted in and about the building to points where the appliance is to be used and suitable connection with the compressed Vair main is made by means of a flexible duct (not shownlwhich connects with the duct 5 and delivers the compressed air through that duct and the nozzle 8 into the exhaust duct 6. x
The compressed air is taken into one side of the vacuum bottle (via duct 5) and is allowed to escape through the very small jet 10 out the opposite or exhaust side ot the bottle, causing a suction on the center or inlet opening of the cover (via duct 11). Practice has demonstrated that it is possible, by the use of our appliance, to have two veryr essential needs in an operating room.. namely, compressed air and vacuum, with the installation of only the compressedair unit besides furnishing a container for the liquids taken up. Both the compressed air and the vacuum are under control of the operator at all times. With an air pressure ranging'from 50 to 150 pounds we have found that our appliance will create a vacuum of approximately seven inches.
a f maare@ All liquids taken up remain in the vessel, which When full, can readily be emptied by removing the cover and dumping the contents.
The invention may be used either by surgeons or dentists. When used by surgeons it is mainly used Jfor the purpose of removing fluids met with during operations, and when used by dentists it is usually used when making impressions or casts to keep liquids from interfering with the operation; the liquids can Vbe removed from the mouth by the use of our invention in a very easy manner.
While We have designed our invention particularly for surgery and dental use still We do not hereby limit ourselves to the use by surgeons and dentists as the invention may be found useful for other purposes than those herein mentioned.
From the foregoing description, taken in connection With the accompanying drawing, it is thought the complete construction, operation and advantages of our invention will be clear to those skilled in the art to which it appertains.
`What we claim is:
A vessel having a removable cap, an exhaust duct mounted on the cap and in communication with the vinterior oi the vessel, a compressed air admission duct mounted on the cap and extended into the vessel, a U- shaped nozzle duct mounted on said admission duct extending transversely beneath the cap Within the vessel and terminating in a discharge orifice, said exhaust duct having a bell mouth into which the discharge orifice end of said nozzle extends, and a third duct carried by the cap and extending into the vessel and terminating above said nozzle 'for delivering material into the vessel by suction produced through rechi-ctionvot1 air pressure Within the vessel substantially as shown and for the purposes described.
