Abstract

Abstract A disposable surgical drape is provided for obstetrical and gynecological operative procedures. The drape consists of a combined plastic tail sheet and nonwoven abdominal cover, and leggings folded into a compact package which may be unfolded directly on a patient without necessitating that the surface in patient contact be handled by the doctor or nurse applying the drape. To this end, the abdominal cover which comprises a rectangular sheet is first longitudinally folded and then fanfolded inwardly from both transverse edges toward the center to form a compact rectangular package. Thereafter the tail sheet and leggings which are affixed to the folded abdominal cover along an edge are transversely fan-folded from both edges and subsequently longitudinally folded to form a second rectangular package some of the folds of which overlie and are interdigitated with those of the first package.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 386 words
A prefolded, disposable, surgical drape adapted to be unfolded in situ on a patient without requiring that the drape be lifted from the patient or that the surface of the drape which comes in contact with the patient be touched during the unfolding procedure, said drape including in combination: an abdominal cover comprising a generally rectangular sheet including a major portion and minor portion separated by a fold line parallel to the longitudinal axis with the minor portion overlying the front surface of the major portion and the sheet fan-folded along lines parallel to the transverse axis dividing the cover into two pluralities of panels overlying the top surface thereof to form a partially folded cover; a tail sheet comprising a generally rectangular sheet of material aligned with its longitudinal axis perpendicular to the longitudinal axis of the abdominal cover and secured to the partially folded cover along the top edge of said tail sheet, said tail sheet longitudinal edges originally extending beyond the transverse edges of said partially folded abdomen cover and fan-folded along lines parallel to its longitudinal axis so as to produce two pluralities of longitudinally extending tail sheet panels, the outermost edges of said longitudinal panels being substantially aligned with the transverse edges of said partially folded abdomen cover; a pair of leggings, each of said leggings being secured to said tail sheet and abdominal cover proximal the interface of said cover and sheet, said leggings each comprising a generally rectangular sheet of material having a longitudinal axis angularly disposed with respect to both said abdomen cover and tail sheet longitudinal axes, said leggings being at least partially folded along with said tail sheet into said longitudinal panels; said drape further comprising a plurality of folds parallel to the transverse axis of said tail sheet dividing said tail sheet and leggings into a plurality of sections, at least one fold line extending across the partially folded abdomen cover parallel to said tail sheet transverse fold lines dividing said partially folded abdomen cover into a top section and a bottom section, said partially folded so that said top section overlies said bottom section and at least one section of said tail sheet and the remaining sections of said tail sheet plurality being folded to overlie both said top and bottom abdomen cover sections.
Claim 2
Dependent Claim 386 words
A prefolded, disposable, surgical drape adapted to be unfolded in situ on a patient without requiring that the drape be lifted from the patient or that the surface of the drape which comes in contact with the patient be touched during the unfolding procedure, said drape including in combination: an abdominal cover comprising a generally rectangular sheet including a major portion and minor portion separated by a fold line parallel to the longitudinal axis with the minor portion overlying the front surface of the major portion and the sheet fan-folded along lines parallel to the transverse axis dividing the cover into two pluralities of panels overlying the top surface thereof to form a partially folded cover; a tail sheet comprising a generally rectangular sheet of material aligned with its longitudinal axis perpendicular to the longitudinal axis of the abdominal cover and secured to the partially folded cover along the top edge of said tail sheet, said tail sheet longitudinal edges originally extending beyond the transverse edges of said partially folded abdomen cover and fan-folded along lines parallel to its longitudinal axis so as to produce two pluralities of longitudinally extending tail sheet panels, the outermost edges of said longitudinal panels being substantially aligned with the transverse edges of said partially folded abdomen cover; a pair of leggings, each of said leggings being secured to said tail sheet and abdominal cover proximal the interface of said cover and sheet, said leggings each comprising a generally rectangular sheet of material having a longitudinal axis angularly disposed with respect to both said abdomen cover and tail sheet longitudinal axes, said leggings being at least partially folded along with said tail sheet into said longitudinal panels; said drape further comprising a plurality of folds parallel to the transverse axis of said tail sheet dividing said tail sheet and leggings into a plurality of sections, at least one fold line extending across the partially folded abdomen cover parallel to said tail sheet transverse fold lines dividing said partially folded abdomen cover into a top section and a bottom section, said partially folded so that said top section overlies said bottom section and at least one section of said tail sheet and the remaining sections of said tail sheet plurality being folded to overlie both said top and bottom abdomen cover sections.
Claim 3
Dependent Claim 119 words
The invention, in accordance with claim 1, wherein each of said leggings comprises a generally rectangular sheet of material folded in half along a line parallel to the transverse axis dividing said sheet into a top layer overlying a bottom layer and including a free transverse edge, a pair of longitudinal edges extending between said fold line and said free transverse edge, a seam extending along one of said longitudinal edges from said fold line toward said free edge for a minor portion of said longitudinal edge joining said top and bottom layers, and a tab forming an extension of said seam, wherein said legging is affixed to said tail sheet and abdominal cover along said other longitudinal edge.
Claim 4
Dependent Claim 25 words
The invention, in accordance with claim 2, wherein said legging layers are joined to one another along the major portion of said other longitudinal edge.
Claim 5
Dependent Claim 32 words
The invention in accordance with claim 2, wherein said leggings extend beyond the top edge of said partially folded abdomen cover anD beyond the longitudinal edges of the originally unfolded tail sheet.
Claim 6
Dependent Claim 44 words
The invention, in accordance with claim 1, wherein said tail sheet further includes an extension beyond the top edge thereof, a trapezoidal cutout centrally disposed within said extension and said leggings are affixed to said extension substantially parallel to the sides of said cutout.
Claim 7
Dependent Claim 31 words
The invention, in accordance with claim 2, wherein said abdomen cover and leggings are formed of a nonwoven material and said tail sheet is formed of a moisture impervious, plastic material.
Claim 8
Dependent Claim 101 words
The invention, in accordance with claim 6 further comprising a backing member of nonwoven material extending downwardly from the top edge of said tail sheet for a minor portion of the length of said tail sheet, said backing member including margins extending beyond the longitudinal edges of said sheet, a fold line parallel to the transverse axis of said sheet substantially bisecting said backing member wherein said minor portion is sides over said fold line and the margins on opposite side of said fold line are glued to one another whereby to define a pocket proximal said tail sheet top edge.
Claim 9
Dependent Claim 20 words
The invention, in accordance with claim 7 further comprising a pad of absorbent material centrally disposed on said tail sheet.
Claim 10
Dependent Claim 71 words
The invention, in accordance with claim 3, wherein said tail sheet includes a generally rectangular main portion and a triangular portion extending upwardly from said main portion, the sides of said triangular portion comprising extensions of the longitudinal edges of said main portion, an oblong cutout disposed within said triangular portion extending along the altitude thereof, and said leggings are affixed to said triangular portion substantially parallel to the sides thereof.
