Specification of Letters Patent.

Patented Aug. 2%, 19215.

Application filed December 22, 1911, Serial No. 667,323. Renewed January 22, 1915. Serial No. 3,837.

To all whom it may concern Be it known that I, ANGELO L. SoREsI, a subject of the King of Italy, residing in New York, in the State of New York, have invented certain new and usefullmprovements in Instruments for the Transfusion of Blood, of which the following is a specification.

The direct transfusion of blood from the artery of one person to the vein of another, or from one vein to another, is considered one of the most valuable therapeutic means of preventing death from hemorrhage, and is very important in many critical cases.

The object of the present invention is to provide means whereby this transfusion may be conveniently and safely accomplished, with the least loss of blood andwith the least injury to the arteries, veins and surrounding tissues.

For this purpose one embodiment of the' invention comprises two split rings or cylinders, one for each blood-vessel, which by opening may be applied to the blood-vessel and then closed to surround the same, said rings being provided with. outwardly-projecting hooks adapted to retain the ends of the parts when the same are cut, and means adjustably connecting the rings so that the same are retained in juxtaposition during the flow of blood. The parts are so arranged and the use of the same is such that no clogging of the blood is occasioned, or any injury to the arteries.

In the accompanying drawing, Figure 1 is a side-elevation, on an enlarged scale, of an instrument embodying my invention, Fi 2 is a section on line 2-2 of Fig. 1, and Fi 3 is a longitudinal section through the instrument, showing the same applied for use.

Similar letters of reference indicate corresponding parts.

in the drawing, the tube 10 for the artery and 11 for the vein, (or vice versa, as desired for use), are made of thin metal, such as silver, and of a size suitable to receive with in them the blood-vessels to be employed in the transfusion, both of said tubes being preferably of the same size, as shown.

One part or half of th ring, tube or cylinder 10 is fixed to or made integral with a post 14:, and the other part of the ring is pivoted to said post 1% by a lug 15, so as to swing freely toward and away from the stationary part 13 of the ring. The hinged portion 16 of the opposite ring 11 is by lug 17 correspondingly pivoted to a slide 18.

blood-vesselswhen the same are turned or cuffed over around the ring by reason of which the inner face of the vessel is not affected by the hooks.

A shank 30 is secured at one end in the post 14 and extends longitudinally of the instrument and parallel with the blood-vessel rings; and upon said shank is slidably supported the slide 18. A set-screw 33, having a handle for convenient and powerful operation, is seated in the slide 18 and adapted to bear against the shank and thereby securely retain the same at any point in the length of the shank. The shank is of rectangular crosssection as shown in Fig. 2, or of other shape so as to retain the rings 10 and 11 always in juxtaposition, that is to say, in opposition on the-same axial line.

In use, the operation is conveniently divided in three stages:

First stagclsolatng the blood-o6sseZa--v After having in the usual manner isolated the blood vessels, a spatula, flat retractor, rubber tissue, etc, will be passed under them, for preventing the hooks catching in the tissues around the wound.

Second stagcPZacin o the cylinders, and im orting the blood oessols over the hooks.- One of the rings, 10 for instance, is opened by swinging its hinged part 12 away from its fixed part 13, and the ring is placed upon the blood-vessel and closed. The ring 11, with its slide, has previously been removed from the shank 18, so as to be out of the way and to be ready for being applied to the other blood-vessel, which is then accomplished in the same manner, the hinged part 16 being opened away from the fixed part 19, and closed again upon the same with the blood-vessel therein. Each blood-vessel is now, without cutting, drawn back or invaginated upon the hooks, as indicated in dotted lines in Fig. 1. This may be conveniently done with pointed forceps.

Third stap er-1V hen both vein and artery, or those parts acting as donor and acceptor, are in aginated over the cylinders, they will be cut with a sharp knife close to the edge of the cylinders, and the latter brought quickly together, by placing the slide upon the shank and moving the same toward the post 14 until the exposed inner faces of the artery and vein abut, as indicated in Fig. 3. V

The set-screw 33 is then operated, whereby the parts are clamped in position. The blood will then run freely from the artery to the vein. The two remaining segments of artery and vein are of course separately tied. When the operation is complete, the continuity of the artery may be re'e'stablished by use of the instrument, the two segments being secured in the cylinders and brought together. Similarly the continuity of the vein may be restored. V

Itwill be noticed that thehinged parts of the rings-are retained in closed position by the blood-vessel, each respectively, which itis carrying. It will also be noticed that by the device the operation is capable of be,-

ing performed very quickly, and no tying of the blood-vessel to be used is necessary, only the unused segments being tied. A mere pinching of the blood-vessel at the instant of transfer is sufiicient to stop the flow for the short length of time required. Thereby the vein or artery is. handled alwaysin completely'open or full position,

being retained in this position by the rings,

instead'of being allowed to empty itself of blood and collapse as in the common methods of performing the operation. these old methods the bloodvessel became a cord, which it was necessary to first open at the end, and manipulate, before reestablishing the flow. The abutting of the blood- ;vessels by use of the new instrument takes place while the blood is there1n,and thereby a tube instead of a cord is worked with.

during the meeting of the members by means of the device. The anastomosis is rapld and easy and 1t is easy to make a temporary anastomosis between blood-vessels.

It is" obvious that changes maybe made in the construction of the instrument, Without departing. fromthe spirit of the invention. V

Having thus described invention, I
