Definitions

• This invention relates to a surgical drape system for protecting a patient from infection.
• Disposable, fenestrated surgical drapes are well-known in the medi ⁇ cal industry.
• An example is U.S. patent 4,401,942.
• fenestrated drapes are often quite large in size so as to completely cover the patient and drape down the sides of the operating table to prevent bacterial contamination of the patient. Because of the numerous sizes and shapes of fenestrations needed for different types of surgical procedures, a hospital must stock a tremendous amount of surgical drapes. Most fenestrated drapes in the past have been made of a single material so that the highly liquid repellent material adjacent the fene ⁇ stration was used throughout the entire drape, including those portions hanging down the sides of the operating room table. The liquid repellent coating or laminated sheet on the drape material that hung down from the sides of the operating room table caused it to be stiffer and less drapeable than desired. Also, it increased the cost of the total drape to make it entirely liquid repellent in order to get the liquid repelleney adjacent the fenestration.
• Patent 3,882,859 has proposed permanently securing a rubber sheet across a very large opening of a surgical drape. The rubber sheet is then split for the surgical incision. However, the rubber sheet does not have a preshaped fenestration. It is simply cut at the time of surgery.
• Patent 4,024,862 has a series of smaller drapes on top of a main drape. Each smaller drape has progressively larger fenestrations. Thus, during a surgical procedure if a larger fenestration is needed, the top drape is simply peeled off and discarded. However, since all drapes are preassembled by the manufacturer, this does not solve the large inventory
• the present invention overcomes the inventory problems, and also provides an improved drapeability to the side areas of a drape hanging over the edges of the operating room table.
• This invention includes a draping system with a separate bottom drape having a fenestration' of the particu- lar size and shape for the surgery.
• This bottom drape is of a highly liquid repellent material, and preferably is adhesively secured directly to the patient.
• a separate top drape of this draping system has an opening larger than the bottom drape's fenestration, but smaller than the entire bottom drape.
• the top drape is adhesively secured in superimposed relationship over the bottom drape.
• the top drape which is adapted to hang over edges of the operating room table, is of a softer, more drapeable material, which can be less liquid repellent than the bottom drape.
• Figure 1 is a top plan view of a first bottom drape with an elongated fenestration
• Figure 2 is a top plan view of a second bottom drape with a different circular fenestration
• Figure 3 is an enlarged sectional view taken along line 3-3 of Figure 1
• Figure 4 is a top plan view of a top drape
• Figure 5 is an exploded view showing the relationship between the top and bottom drapes and the patient.
• FIG. 1 a first embodiment of a bottom drape 1 is shown.
• This drape has an elongated fenestration 2 and a pair of adhesive strip members 3 and 4 adjacent fenestration 2.
• FIG. 2 A second embodiment of a bottom drape 5 is shown in Figure 2, and this bottom drape has a fenestration 6 that is of a circular shape. Also, in the bottom of drape 5 is a pair of adhesive members 7 and 8 adjacent fenestration 6.
• the drape is shown as composed of a main body 10 which can be of a nonwoven, cellulosic material. A bottom surface of the main body 10 is preferably laminated to a liquid repellent layer 11. Layer 11 can be a liquid repellent coating or a separate thermoplastic film bonded to the main body 10 of bottom drape 5.
• a top drape 15 which is much larger than the bottom drape, can have any desired configuration, as shown in Figure 4.
• the top drape is illustrated as having a generally T-shape.
• the top drape has a large opening 16 which is shown with cut or notched corners defining flaps which have adhesive strips 17, 18, 19, and 20 on their bottom surfaces.
• the top drape can also include a slip resistant pad, such as a rubber sheet 21, for laying surgical instruments on during an operation.
• the top drape 15 is superimposed on bottom drape 5, and secured to the bottom drape by adhesive strips 17, 18, 19, and 20.
• the bottom drape 5 can be of a more liquid repellent material even though such liquid repellent material may have a more stiff, paper-like characteristic that is undesirble for an entire surgical drape.
• the top drape since it is protected from the surgical site by the bottom drape, can be of a softer, more drapeable, cloth-like material, such as a nonwoven, cellulosie material having less liquid repellent characteristics.
• the outer drape can thus more readily drape and follow the contours of the patient, operating room table, etc. as would a cloth drape.
• the top drape can be made of a less expensive material which need not have all of the liquid repellent characteristics, etc. Also, if desired, the more critical bottom drape can have additional bactericidal agents, etc. that may not be required with the top drape. In short, two separate materials can be used for the bottom and top drape.
• the hospital can stock only a variety of the small bottom drapes with different sizes and shapes of fenestrations.
• the hospital can stock only a standardized top sheet which can be used with many different bottom sheets having different sizes and shapes of fenestrations.
• a hospital need not stock a a large number of complete drapes which may be in the order of. 6' x 10' simply to get the different sizes and shapes of fenestration needed for the various surgical procedures.
