Description

Oct. 8, 1957 w. AUGUST GAS BLANKETED CLOTTING INSTRUMENT Filed Dec. 6, 1952 INVENTOR. MLL/A/ /"fluaus 7 BY E, I
United States Patent 2,808,833 GAS BLANKETED CLOTTING INSTRUMENT William August, Arcadia, Calif., assignor to The Birtcher Corporation, Los Angeles, Calif., a corporation of California Application December 6, 1952, Serial No. 324,515 4 Claims. o]. 128303.17)
This invention relates to a clotting instrument.
It has been determined that blood can be coagulated by a high frequency current of given characteristics. Frequently such action takes place in an operating room wherein the air is charged with anesthetic. Since many anesthetics are explosive, there is considerable danger of an explosion from sparks caused by the current carrying instrument.
It is, therefore, an object of this invention to provide a high frequency current carrying member which is electrically insulated from the atmosphere.
It is a further object of this invention to provide means for enveloping the operative extremity of the clotting instrument in an inert gas to avoid possible explosion.
It is still a further object of this invention to provide a high frequency current carrying member which is insulated from the atmosphere and enveloped in an inert gas to avoid possible explosion.
Other objects and advantages will be readily apparent from the following description:
In the drawings:
Figure 1 is an elevation of a clotting instrument embodying this invention.
Figure 2 is a section taken along line 22 of Figure 1.
Figure 3 is a fragmentary view of the current carrying tube with the gas tube in section.
Figure 4 is a section taken along line 44 of Figure l with an insulating coating added.
Figure 5 is a section taken along line 5-5 of Figure 2 with an insulating coat added.
The clotting instrument'is in this embodiment in the form of a tube having an enlarged head of clotting tool 12 at one extremity. The other extremity has a flange 14 and a nipple 16. The nipple is corrugated as at 18 adapting same to telescopically receive the flexible tubing 20 which is secured thereon by bands 22, which tubing is of a suitable electrically non-conductive material.
The hollow tubing 20 is at its other extremity connected to a reduced pressure source such as a suitable vacuum pump so that air is drawn through the tube 10. An aperture 24 is provided in the tube 10 with a suitable curved finger plate 26 having a corresponding aperture therein attached to the tube 10. Thus when the aperture 24 is unobstructed no suction is created at the head 12,
but when the thumb of the user covers the aperture 24 a suction is created at the head 12 so that excess blood can be siphoned through the instrument.
Surrounding the tube 10 adjacent the head bearing extremity is a gas tube 26 which has a threaded head 28 thereon. A knurled nut 30 screws onto the head and packing 32 is a 2 2,808,833 Patented Oct. 8, 1957 recting tube 38 directs flow from the tube 34 into gas tube 26.
Spiral teeth 40 are formed 'on the clotting tool tube 10 to insure that it remains centrally located in gas tube 26 and that flow of gas through the gas tubejis unobstructed. The spiral fiutingbetween teeth form gas channels and impart a rotary motion to the flowing gas insuring no voids in the gas blanket.
One lead from a high frequency current source is attached to the patient; The other lead is wire 42 which is inside of tube 34 so it is insulated from the atmosphere; This wire passes through gas flow .directing'tube 38 and is secured to the clotting tool"tube"10 by means of sleeve 44.
The instrument with the exception of that portion of the clotting tool tube 10 within gas tube 26 is coated with an electrically non-conductive material, such as rubber or the like, to insulate same from the atmosphere avoiding the possibility of a spark causing an explosion. This insulation has not been illustrated in Figures 1, 2 and 3 toavoid complication of the drawings. Of course, the head 12 of the clotting tool is not insulated.
In operation, high frequency current is supplied to head 12 through wire 42 through suitable control means. Inert gas is directed into gas tube 26 from tube 34 and is discharged. at the extremity thereof in the form of an envelope encasinghead 12 and eliminating it as a source of an explosion causing spark. The head 12 is first incess blood has been drained in this manner, the high frequency current source is energized causing the re maining blood to clot.
While What hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that alterations and modifications can be resorted to without departing from the scope of this invention, which alterations and modifications are intended to be within the scope of the following claims:
I claim:
