WOUND DRAIN STRIP Filed Jan. 6, 1957 Patented Oct. 25, 1938 UNITED STATES PATENT OFFICE WOUND DRAIN-STRIP Ludwig Schwarzmayr, San Francisco, Calif. Application January 6, 1937, Serial No. 119,242

3 Claims.

My invention relates to improvements in Wound drain-strips; and the object of my improvement is to facilitate inserting into and properly placing the soft and relatively thin drain-strip in deep wounds.

I attain these objects by the construction illustrated in the accompanying drawing, in which- Figure 1 is a view of the drain-strip; Fig. 2 is the drain-strip as shown in Fig. 1, with the inserting instrument in operative position; Fig. 3 is a sectional view on line 3, 3 in Fig. 1; Fig. 4 is a modification, showing a drain-strip with two pockets providing holding means for a two pointed inserting instrument; Fig. 5 is a drainstrip as shown in Fig. 4 with a two pointed inserting instrument in operative position; Fig. 6, a sectional View on'the line 6, 6, Fig. 4; Fig. 7 is a modification showing two strips extending from a pocket; Fig. 8, a sectional view on line 8, 8 in Fig. 7; Fig. 9, a modification of a drainstrip having ribs forming channels between them; and Fig. 10 is a cross section of the strip on line l0, ID in Fig. 9.

Thin, soft rubber strips are in common use'in draining wounds. To insert and place them in the desired position in deep wounds is sometimes difficult, and through the manipulation with the inserting instrument often pain is caused. To facilitate inserting and positioning of the drain- 30 strip into wounds I provide the soft rubber strip l with a pocket 2 on one of its sides at one end thereof to furnish a holding means for the inserting instrument 3. (See Fig. 2.) When the inserting instrument is removed the member forming the pocket fits itself snugly to the strip. Channels 4 on each side of the strip provide a drainage throughout the entire depth of the wound. Figs. 4 and 5 show a modification in which the drain-strip 5 has two pockets 6, 6 to accommodate the two ends 1, I of the inserting instrument 8, whereby a relatively wide drainstrip of soft rubber may correctly be disposed. The proper placement of a wide drain-strip is especially desirable in deep and wide wounds such as he often caused by pieces from exploding shells. Fig. 7 shows a modification in which the drain-strips 9, 9 made of soft rubber are of a circular cross section, as shown in Fig. 8, and have a pocket ID at one end for the inserting instrument. The recesses H, II between the strips provide the drain channels. This type facilitates the draining of deep and narrow o wounds, such as often are caused by nails in the palm of the hand of a laborer, where it is desirable not to cut the opening bigger than it is. Figs. 9 and 10 show a modification in which the soft rubber drain-strip 12 has ribs l3, l3 forming 10 channels M, M between them. The ribs l3, l3 are arranged in a staggered relation relative to those projecting from the opposite side of the strip so to avoid longitudinal stiffening of the drain-strip. In extremely wide drain-strips it 15 is desirable to have a greater number of pockets than shown in the drawing so that the edge of the pocket wall is short to keep closely to the strip so not to cause obstruction when the strip is taken from the wound. 20

I claim:

1. A wound drain-strip having a thin and. flexible body to adapt itself to the contour of a wound, one side of said body having a pocket at one end thereof to engage the end of an inserting instrument, said pocket being relatively short and its outside wall adapting itself snugly to the side of said body after the removal of the inserting instrument to prevent its edge from abutting against the tissues of the wound when the drain-strip be removed therefrom.

2. A relatively thin and wide drain-strip having means removably attaching one of its ends to the end of an inserting instrument to retain the wound drain-strip in its wide position when in- 5 serted in a wound, said means comprising two instrument engaging members positioned oppositely to each other and at the two edges of the wound drain-strip.

3. A relatively wide wound drain-strip having means removably attaching one of its ends to the end of an inserting-instrument to retain the wound drain-strip in its wide position when inserted into a wound, said means comprising a plurality of pockets arranged at one end of the 5 wound drain-strip.
