To aZZ whom it may concern.-

Be it known that I, WILLIAM O. SOHROYER, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and use ful Improvements in Embalming Instruments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in a device for draining blood from the venous system of a human body, and comprises means whereby the blood may be easily and quicklyremoved from the body, whereby the essential results of the embalming of the body may be obtained.

The object of my invention is to provide a blood-removing tube which will reach the fountain-head of all the blood in the human body, which is the inferior vena com, the heart, and the superior oena caoa, by inserting the tube in the external illiac vein-and passing the tube through the latter to its juncture with the inferior vena cam vein, means being provided to hold the vein distended without in any way cutting the wall of the vein and affording means whereby the blood may readily flow into the tube and be drained from the system.

My invention comprises, specifically, a tube having at one end an open-work of wires which are spaced apart and have flaring portions which are tapering to a blunt point, thus affording passage-ways for the blood to flow into the tube without interruption, means being provided to prevent the blood from escaping through the opening in the open-work as the tube is inserted through the incision made in the vein.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my invention. Fig. 2 is a similar view showing one end of the device inserted throu h an incision in the vein with the extensible sliell upon the tube withdrawn from over the open-work at the end, and Fig. 3 is a similar view showing the shell extended over a portion of the openwork at the end of the tube to cause the blood issuing from the vein to pass through the tube.

Reference now being had to the details of the drawings by letter, a designates an openended tube having a shoulder 0/ at one end, over which the end of the tube may be caught to convey venous blood as it issues from the venous system of the body. One end of said tube has an open-work consisting of wires 6, which are spaced apart, and their outer edges are flush with the circumference of the tubular portion. Each ofsaid wires 6 flares outwardly at b, and each wire isbent at its center, forming a swelled head which dilates the vein and holds it open while the embalmer is operating. Said head and openwork will catch and hold any blood-clots that may get into it, and the same-may be easily removed from the vein while removing the tube temporarily from the vein. The straight portion of the open-work at the end of the tube will allow the blood to pass any blood- }clots which may lodge in the swelled head.

The straight portions of the wire forming the open-work also hold the vein open and will not allow it to collapse, which has heretofore been a trouble frequently met with by embalmers in their efforts to remove the blood from the system.

Telescoping over the tubular portion of the device is a shell 0, which is adapted to be pushed over the open-work formed by the wires at the end of the tube, as shown in Fig. 3 of the drawings, for the purpose of preventing any blood escaping through the spaces intermediate the wires and causing the liquid to pass through the tubular portion a.

In Fig. 2 of the drawings I have shown the wire open-work at the end of the tube as being passed through a slit in the external illiac vein, (desi nated by letter d in the drawings,) which vein has been made accessible, preferably, at a position over the pelvic bone.

In the application of my device the external illiac vein is raised and slitted, and after the flaring end of the open-work at the end of the tube is inserted into the vein the latter is distended, as shown in Figs. 2 and 3 of the drawings, and a slide 0 is pushed up adjacent to the slit and up to the flaring portions of the wire and held against the marginal edges of the slit while the tube is being forced into the vein, the tapering portions of the flaring ends of the device serving to guide the instrument easily and quickly drained of blood in prepar-' through the vein to a location at the juncture of the illiac vein with the inferior vena cam.

vein, where the blood is drawnfrom the latter and allowed to pass through the tube and drawn away.

From the foregoing it will be observed that a simple and efficient means is provided wherebythe system of a human body may be circulation through every part of the body.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A device for draining blood from the venous system of a human body, consisting of a tube, having awire open-work atone end adapted to be inserted into a vein of the body and to withdraw the blood therefrom, as set,

forth.

2. A device for draining blood from the venous system of a human body, consisting of a tube having a wire open-work at one end adapted to be inserted into a vein of the body and to withdraw the blood therefrom, and means for preventing the escape of the blood through the open-work at the end thereof, as set forth.

3. A device for draining blood from the in which the embalming fluid is venous system of a human body, consisting of a tube, having a wire open-work at one end adapted to be inserted into a vein of the body and to withdraw the blood therefrom, a shell mounted upon said tube and adapted to telescope over said open-work, as set forth.

4. A device for draining blood from the venous system of the human body, comprising a tube having wires projecting from one end thereof, spaced apart, said wires being outwardly flaring to form means for distending a vein, as set forth.

5. A device for draining blood from the venous system of the human body, comprising a tube having wires projecting from one end thereof, spaced apart, saidwires being outwardly flaring to form means for distend ing a vein, and a shell mounted upon said tube, and adapted to slide over said wires and limited in its movement in one direction by the flaring portions of the wire, as set forth.

6. A device for draining blood from the venous system of the human body, consisting of a tube having wires which are-bent at their longitudinal center, forming a blunt point, and

flared adjacent to said point, the ends of said wires being fastened to said tube and spaced apart, and a shell telescoping over said tube, and adapted to slide over said wires and against the flaring portions thereof to prevent the escape of blood between the open spaces between the wires, as set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
