Abstract

Abstract Disposable surgical drape especially adapted for use in cardiovascular procedures is disclosed. The drape is preferably made from a generally rectangular main sheet of a flexible, repellent nonwoven fabric. The fenestration area of the drape is substantially centrally located widthwise and extends from near the patient foot end towards the patient head end at least past the area covering the patient's chest. Preferably an additional reinforced work area is provided at the patient head directed end. The fenestration is provided by means of a split extending from the patient foot end forming tails which may be positioned as desired to shape the fenestration. The drape is positioned and the tails maintained in place by attachment to the patient with medical grade adhesive strips applied to the underside of the drape. As a particular feature of the invention, raised reinforced flaps are provided adjacent the split to provide attachment sites for clamps, tubing, cords and the like. Also, pockets are provided for containing and organizing instruments. In a preferred embodiment, the pockets are formed so that they may be opened if desired to expand the reinforced area surrounding the fenestration. Also disclosed are preferred means for assembling and folding the drape as well as preferred materials including a nonwoven laminate of spunbonded and meltblown polypropylene fibers and preferred reinforcing material of a film/foam laminate. The resulting drape contributes to the flexibility and efficiency of the operating room thereby helping to reduce surgery time and benefitting the patient.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 201 words
Surgical drape comprising: (a) a main sheet of flexible, water repellent, nonwoven material having lateral edges, a patient head end and patient foot end, a patient facing surface and an opposite surface, said sheet having dimensions sufficient at least to cover the legs, torso, and chest areas of the intended patient; (b) a split in said main sheet extending from a central area of the foot end towards the head end forming tail portions and having dimensions to form a fenestration at least sufficient to permit exposure of one or both legs of the patient as desired; (c) pocket means disposed adjacent said split and adapted to receive equipment associated with the intended procedure wherein said pocket means includes slits permitting tubing, wires or cords to be routed through and a pocket to be opened out if desired for additional reinforcement in the fenestration area; (d) flaps adjacent said split for receiving means adapted to maintain tubing, wires and the like in place; and (e) adhesive attachment means adjacent said split on the patient facing surface and adapted to secure said drape in place on the patient while permitting adjustment of exposed patient surface area by location of said tail portions.
Claim 2
Dependent Claim 201 words
Surgical drape comprising: (a) a main sheet of flexible, water repellent, nonwoven material having lateral edges, a patient head end and patient foot end, a patient facing surface and an opposite surface, said sheet having dimensions sufficient at least to cover the legs, torso, and chest areas of the intended patient; (b) a split in said main sheet extending from a central area of the foot end towards the head end forming tail portions and having dimensions to form a fenestration at least sufficient to permit exposure of one or both legs of the patient as desired; (c) pocket means disposed adjacent said split and adapted to receive equipment associated with the intended procedure wherein said pocket means includes slits permitting tubing, wires or cords to be routed through and a pocket to be opened out if desired for additional reinforcement in the fenestration area; (d) flaps adjacent said split for receiving means adapted to maintain tubing, wires and the like in place; and (e) adhesive attachment means adjacent said split on the patient facing surface and adapted to secure said drape in place on the patient while permitting adjustment of exposed patient surface area by location of said tail portions.
Claim 3
Dependent Claim 22 words
