March 24, 1953 E. P. LESHER SURGICAL DRESSING Filed April 18, 1949 Fig.2.

Inventor a h s e L R. W a e I E (wig away 8M5 Patented Mar. 24, 1953 UNITED STATES PATENT OFFICE SURGICAL DRESSING Eleanor P. Lesher, Wareham, Mass.

Application April 18, 1949, Serial No. 88,127

1 Claim. 1

This invention relates to surgical dressings, and the primary object of the invention is to provide such a dressing including a fiat inner absorbent pad having a large central aperture of such shape and size that its wall will surround the wound to be dressed, and a conventional imperforate fiat outer absorbent pad superimposed on the apertured pad so as to close the aperture of the latter and define a closed reservoir for receiving drainage directly from the wound and retaining such drainage until it is completely absorbed by the pads. In this way, the drainage is confined to and prevented from seeping out be yond the dressing area, as often occurs when an ordinary imperforate pad is placed directly over and upon the wound. Also, the dressing can be easily removed without discomfort to the patient because the pads do not touch or adhere to the wound.

One embodiment of the invention is shown in the accompanying drawings, in which:

Figure 1 is a sectional view of a dressing constructed in accordance with the present invention;

Figure 2 is a plan view of the inner pad, the outer pad and the pad retaining means being removed;

Figure 3 is a section taken on the line 3-3 of Figure 2.

Referring in detail to the drawings, 5 indicates a fiat inner absorbent pad having a large central aperture or opening 6 of such a size and shape that its wall surrounds the wound I to be dressed. This pad consists of a relatively thick layer 8 of absorbent cotton covered at the side edges and on its inner and outer surfaces by gauze as at 9 and I0, and also preferably having the wall of aperture 6 covered by the gauze as at H so that layer 8 is properly confined and held in shape.

An ordinary flat imperforate outer absorbent pad I2 is superimposed on the inner pad 5 so as to close the opening and define a closed reservoir for receiving drainage directly from the wound 1 and retaining such drainage until it is absorbed by the pads near the region of the 5 wound. The pad I! also consists of a relatively thick layer of absorbent cotton l3 having its side edges and its surfaces covered with gauze Hi. The pads are preferably of substantially the same area.

The pads may be secured in place by any well known or preferred means, such as a wrapping of gauze l5, adhesive tapes or straps, etc.

From the foregoing description, it is believed that the nature and advantages of the invention will be obvious to those skilled in the art.

Having described the invention, what is claimed as new is:

A surgical dressing for a flesh wound comprising a fiat absorbent pad having a central opening for surrounding the wound, a gauze covering the said pad enclosing all surfaces of the pad around said opening to hold said pad in shape and providing a gauze bottom on said pad for engaging the flesh around the wound, and a second fiat imperforate pad of absorbent material imposed on said first pad to close the opening and having a gauze covering completely enclosing the same to maintain said second pad in shape and provide a gauze bottom on said second pad contacting the gauze covering on the first pad to reduce adhesion between said pads resulting from absorption of moisture from the wound.
