Specification of Letters Patent.
Patented Jan; 18, 1921.
Application filed February 8, 1918, Serial No. 216,016. Renewed June 18, 1920. Serial No. 389,962.
To all whom it may concern:
Be it known that I, Dr. CHARLES F. Donsnr, of the town of Iroquois Falls, in the district of Temiskaming, Province of Ontario, Canada, have invented certain new and useful Improvements in Tourniquets, of which the following is a specification.
This invention relates to devices used to sels in cases of injuries to or operations on the limbs and head, and my object is to do vise a simple construction for this purpose which is easily applied, which permits of any desired pressure being exerted on the limb and which will conform itself to irregularities in the contour of the limb to which it is applied so as to produce an equal elastic pressure at all points.
I attain my objects by means of the constructions hereinafter described and illus trated in the accompanying drawings in which- Figure 1 is a perspective view of my improved tourniquet;
Fig. 2 a side elevation showing the same loosely coiled; and
Fig. 3 a cross section through the coiled tourniquet.
In the drawings like numerals of reference indicate corresponding parts in the different figures.
The device comprises a bandage 1 of any suitable textile fabric. To one end of this bandage is connected an inflatable bag. The preferable arrangement is to form a pocket 2 in one end of the bandage and insert an inflatable bag 3 therein. The pocket, and therefore, the bag, is preferably narrower than the bandage so that when the device is placed in position about a limb the band age will overlap and completely cover the rubber bag in its pocket as shown in Fig. 3. The bandage is also preferably so con structed as to bag in the middle, so that when wrapped about the limb it will assume the concave form shown in Fig. 3, thus completely covering over the inflatable bag and preventing its lateral displacement.
The pocket 2 is preferably open at one end, which end is provided with av closing flap 4 which may be held in the closed position by means of a dome fastener 5, so that the bag can be removed and the fabric of the of the pocket. stop the flow of blood through the blood ves- For convenience in securing the device in position a fastening strip 8 is provided con nected to the opposite end of the bandage from the rubber bag. This fastening strip is preferably narrower than the bandage.
While various means may be employed to give the bandage the necessary bag, I show the bagginess as formed by sewing small folds along each edge, thus shortening these edges while the center part remains of full length.
While I do not wish to restrict myself to any sizes, the rubber bag is preferably about fourteen inches lone by about two inches wide, so that it will, when the tourniquet is in place, very nearly encircle the limb to which it is applied.
The device is used by first placing the inflatable bao: around the limb, taking care that the inflatable bag is over the blood ves sels through which the flow of blood is to be stopped. The bandage is then wrapped around the limb over the inflatable bag, as indicated in Figs. 2 and 3, and suitably secured in place by means of the fastening Strip 8. The bag is then inflated to any necessary pressure by means of the air pump 6. With this arrangement any desired pres sure may be exerted and not only is the pressure an elastic one, but the pressure will be applied equally at all points in the circumference of the limb no matter what irregularities in the contours of the limb there may be. I thus insure that ample pressure will be exerted over the blood vessels without undue pressure being exerted over bones, tendons or other such parts.
What I claim as my invention is 1. As a tourniquet, anarrow inflatable bag and a bandage connected at one end with said baogsaid bandage beino: wider and bag and a bandage connected at one end with the main part of the bandage and provided said bag, said bandage being wider and with a closin r flap, and an inflatable bag 10 longer than said bag, and said bandage being adapted to fit in said pocket, and a fastening shaped to bag between the edges, and a fasstrip narrower than the bandage and con- 5 tening stripnarroweithan the bandage and nected to its other end.
