Description
W. H. BARNES. SURGICAL INSTRUMENT. APPLICATION FILED H0129. 1907.
900,343. Patented 0011.6,1908.
IHIHUHILL HUT-7 pnrrnn srArss PATENT onnron WILLIAM HENRY BARNES, OF HOM'EWOOD, MISSISSIPPI SURGICAL INSTRUMENT.
Specification of Letters Patent.
Patented Oct. 6, 1908.
Application filed November 29, 1907. Serial No. 404,471.
To all whom it may concern: a
Be it known that I, WILLIAM HENRY BARNES, a citizen of the United'States, residing at Homewood, in the countyof Scott and State of Mississippi, have invented certain new and useful Improvements in Surgical Instruments, of whichthe following is a specification.
' fetus.
of the child is causedby asphyxiation, when This invention provides an instrument for use in connection with childbirth, in thecase of breech presentations, to conduct air to the In many cases ofstillbirth the death a large proportion of them could be'saved by proper ventilation,and it is for this purpose that the instrument provided by this invention; is designed. V I I When read in connection with the description herein, the formation and details ofthe ings, 6 designates a spoon-like somewhat flattened portion having a concaveor hollowed out portion 7 therein. Extending from portion 6 is a grip portion-8, formed by reducing the material extending from the spoon like portion, and leaving a substantially flat cross 1 surface 9. Extending from this surface to the bowl 7 is an air orventilating conduit 10.
The material of the instrument coincident with surface 9 is somewhat'raised above the remainder of the spoon-like portion, to re duce the liability of tissues slipping thereover and interfering with entrance of air into passagelO. 3
The instrument should be made of metal, hard rubber, or any other suitable non-a o sorbent material capable of receiving. a high polish and of being readily sterilized- I The instrument is to be used in breech presentations, when the body of. the child is expelled and the expulsion pains stop. In such cases the child will ordinarily soon die from asphyxia. By inserting this instrument, however, and fitting its bowl portion over the mouth of the child, it receives air and can breathe and live until the head can be'expelled. The bowl or spoon-like portion being somewhat flattened, the instrument may be readily inserted to the proper position without injury to the mother or to the fetus; and the instrument is sufiiciently broad at its flattened portion to entirely cover the mouth of'the fetus, so as to prevent surrounding tissues stopping up the mouth and. interfering with respiration through the air-conduit. v
To introduce the ventilator, when the body of the child is expelled and the pains stop, leaving the head inthe mother, the physician raises the child with one hand, or has his assistant do it, then inserts a finger, draws down the chin slightly, and passes the instrument under the chin and over the mouth, letting the upper or spoon end rest on the upper maxillary bone, whereby the spoonlike bowl'will be over the mouth of the child and the air-passage in communication with the childs mouth, whereby air is furnished to the child during the period mentioned. The instrument may remain in this position until the head is expelled, as it does not interfere with the exit of the head, the instrument coming away with the head; or, if desired, the instrument may be Withdrawn just be- ,fore exitof the head. 7
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-
1 An instrument comprising a hollowed out portion adapted to be inserted into a motherat childbirth, a grip portion extend- .ingfrom said hollowed out portion in a man- :ner to project from the mother when the instrument is in' place, and an air-conduit extending from the hollowed out portion to the projecting end of the grip portion, said instrument being of general flattened contour throughout its length, and crossed on the side opposite to the hollowed out portion by a raised portion, and being adapted to lie with itsihollowed out portion over themouth and against the chin of the fetus.
2. An instrument comprising a spoon-like bowled portion on one side adapted to be insorted into a mother at childbirth, a grip portion extendedtherefrom, a raised portion adjacent to the'grip portion on the side of the instrument opposite to the spoon-like pori In testimony whereof I have eflixed my tion, and an air-conduit extending from the signature, in presence of two witnesses. bowled portion toward the end of the rip T r 7 portion, the instrument from end to end on XVILLIAM Huh hi 5 the side with the bowled portion being fiat- Witnesses:
J. L. TANNER,
tened and arranged to lie over the mouth and against the chin of a fetus. 1 O. H. NOBLIN.
