ABSTRACT OF THE DISCLOSURE A surgical drape is disclosed which comprises a main body portion having a surgical access opening therein adjacent the top edge midway between the side edges. The main body portion is also provided with leg receiving pockets on opposite sides of the access opening which open both downwardly from the top edge and inwardly toward the said opening. A cover member is also provided which extends above the top edge of the main portion between the leg pockets. The area around the access openbe provided with a reinforcing panel. In use the drape is used during gynecological r lithotomy operations.

The present invention relates broadly to hospital operating room supplies and more specifically to an improved gynecology or lithotomy drape.

In preparing for obstetrical, gynecological, and lithotomy operations or the like, it is standard practice to place the patient on an operating or delivery table with the legs elevated and the patients feet supported in stirrups. According to common practice several years ago with this type of work the table would be first covered with a linen patient would be laid on this entailed considerable distasteful hand work, the work, such as delivery, was over there was the matter of linen repairs, preparation of packs for the next delivery or surgical procedure, storage, autoclaving, and miscellaneous expense for linen handling and laundering as well as a large investment in linens. These linens also let blood and other fluids pass through them and thus transmit microorganisms and contamination even though the linens were initially sterile. Also, some stains are extremely diflicult to remove from these linens, and may form the starting point or starting source for infection, particularly when hard to kill organisms are involved and perfect sterilization has not been attained. It was a recogdue to passage of infecting organisms through the open spaces between threads of the cloth or so called linens, the large linen investment of hospitals in the operating room portion of same, and the need of some wayv to reduce costs and laundry work which led to the conception and development of my invention set forth in my copending patent application for a Disposable Obstetrical and/or Surgical Cover Means, Ser. No. 797,811, now Patent No. 3,030,957, which, in turn, was a continuation-in-part of my previous patent application 402,989, filed January 8, 1954, now abandoned. The subject matter of that invention, which involves special forms of disposable obstetrical and/or surgical cover means made from disposable non-woven material, which can be generally referred to as a cellulose fabric, has gone into widespread commercial use. The use of that invention led to the realization that an improved and simplified form of drape for full covering of the patient was desirable, and same resulted in the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of an improved gynecology or lithotomy drape of unitary form which has no separate leggings to table with the patient's legs and feet supported in elevated position by means of stirrups.

Another object is to provide a gynecology or lithotomy drape having a new and improved form adapted to overcome all or at least most of the shortcomings and disadvantages of previous drapes used for this purpose.

Another object is to provide a gynecology or lithotomy drape having a new and improved form adapted to overcome all or at least most of the shortcomings and disadvantages of previous drapes used for this purpose, and at the same time involving very simple procedures.

Another object is to provide a gynecology or lithotomy drape which can be made of any suitable material, but preferably of non-woven disposable material.

Another object is to provide a gynecology or lithotomy drape which avoids the previous difliculties of having to thread the patients legs and feet, while supported in raised position on stirrups, into tubular members such as leggings which are a unit portion of drape itself.

A further object is to provide a gynecology or lithotomy drape which is easy to form and exceptionally easy to drape over a patient resting on an operating or delivery table.

A further object is to provide a gynecology or lithotomy drape which, when placed over a patient resting on an operating or delivery table provides a full blanket type construction.

A further object is to to the under face of the assembled drape, as by gluing so as to produce a smooth rounded edge opening.

Still further objects and advantages of the invention will appear as the description proceeds.

To the accomplishment of the ends, the invention, then,

detail certain means for carrying out the invention, illustrating, various ways in which the principle of the invention may be used.

In the annexed drawings:

FIGURE 1 is a perspective view showing the gynecology or lithotomy drape of the present invention positioned for use in an obstetrical, external gynecological, rectal, perineal, or similar operation.

FIGURE 2 is a plan view of a preferred form of the back or under face of the gynecology or lithotomy drape as illustrated in use in FIGURE 1.

FIGURE 3 is an exploded view of the back or under face of the blanks for forming the gynecology or lithotomy drape ready for folding into completed form as shown in FIGURE 2.

FIGURE 4 is a perspective view showing the same back face of the blanks of FIGURE 3 in the course of being folded and finished into the drape form shown in FIGURE 2.

FIGURE 5 is a sectional view as taken along line 5-5 of FIGURE 2, looking in the direction of the arrows.

FIGURE 6 is a sectional view as taken along line 6-6 of FIGURE 2, looking in the direction of the arrows.

FIGURE 7 is a sectional view as taken along line 7-7 of FIGURE 2, looking in the direction of the arrows, and with the reinforcing flaps shown in the course of being folded down and anchored in finished position.

FIGURE 8 is a sectional view as taken along line 8-8 of FIGURE 2. and with the reinforcing flaps shown in the course of being folded down in similar manner to the showing in FIGURE 7.

Referring more particularly to FIGURE 1 of the drawings, it will be noted that there is shown an operating or delivery table 10 on which is resting a patient 11 with her feet 12 supported in stirrups 13, and covered by a gyne cology or lithotorny drape 14, which may be broadly referred to as a surgical drape and will be hereinafter described in detail.

The blank for which the gynecology or lithotomy drape 14 is made can be of one piece. However, in that case an exceptionally large sheet would have to be used, and there would be a considerable cutting to waste. Referring to FIGURE 3, it will be noted that here the blank is shown as made up of two pieces in the form of the main body member 15 and the patients abdomen covering portion 16. FIGURE 3 also shows the back or under the side portion of the drape 14 and wherein the main body member 15 has a main panel 17, with a hinged fold line 18 extending all the way across the upper portion of main panel 17. Joined to main panel 17 by means of this hinged fold line are left and right panel members 19 and 20 and a reinforcing panel 21. This reinforcing panel is preferably coated with adhesive 22 and is provided with an operating opening 29. Left panel member 19 has a diagonal fold line 23, about which flap portion 19a is foldable. Likewise right panel 20 is provided with a diagonal fold line 24 about which flap portion 20a is foldable. Left panel member 19 and its flap portion 19a have glue strips 25 and 26 at the side edges of same, as shown, for a purpose to be hereinafter described. Likewise, right panel member 20 and its flap portion 20a have glue strips 27 and 28 at the side edges of same, as shown, for a purpose to be hereinafter described.

Main panel 17, adjacent hinged fold line 18 and midlength of same directly in line with opening 29 and reinforcing panel 21, is provided wiih an opening 30 by means of a slit 31 having Y-shaped ends. This opening 30 is approximately the same size as opening 29 in reinforcing panel 21. The area which becomes opening 30 is also provided with a glued area 32, as shown, for a purpose to be hereinafter described. The abdomen covering portion 16, FIGURE 3, is provided on its under face with a glue strip 33, the use of which will be hereinafter described.

Now referring to FIGURE 4, it will be noted that the left panel member 19, right panel member 20, and reinforcing panel 21 have been partially folded down to final position and flap portions 19a and 20a have been respectively partially folded back about the r diagonal fold linfi 23 and 24. The abdomen covering portion 16 has also been removed down toward its final position. When these various panels are passed to their fully folded position and adhesively fastened together the blank will take on the appearance shown in FIGURE 2.

When the reinforcing panel 21, FIGURE 4 is folded all the way down to the position shown in FIGURE 2, its opening 29 will line up with and be directly over the opening 30 shown in FIGURE 3. With the parts in this position, the flap members 34, 35, 36 and 37 are pushed through the opening 29, and take on the appearance shown in FIGURES 7 and 8. When these flaps are pushed all the way down into contact with the face of reinforcing panel 21 and adhesively fastened thereto they will take on the appearance shown in FIGURE 2 thus producing a smooth, reinforced, rounded edge opening through which obstetrical, gynecological, or other surgical work on a patient can be done.

By forming the drape as shown in FIGURE 2, it is to be noted that same has left and right pockets 38 and 39 into which the stirrup supported feet of the patient may be readily slipped so as to take the position shown in FIGURE 1, under conditions of use. These pockets 38 and 39 avoid the need of unit joined leggings, or for that matter separate individual leggings, and make it exceedingly easy for the sterile nurses, internes, surgeons, or obstetricians to slip the whole drape over the patient so as to give a sterile full blanket type cover for the patient with her feet in the pockets without the bother of thread ing the patients feet and legs into either fixed or separate leggings as in past practice.

A preferred type of material out of which to make the present drape is a disposable non-woven fiberous material having good wet strength with low water absorbency, and which may be of cellulosic material or other material commony referred to as paper, or even a sheet in the form of a mat of synthetic fibers. For added strength this nonwoven material may have a network of yarn type reinforcing fibers embedded therein, with nyon" fibers being a preferred type of reinforcing material. A thoroughly satisfactory non-woven fabric for the present drape is currently being sold under the trademark name of Kaycel.
