Barrier eye drape and method of using same
First Claim
1. A barrier eye drape, comprising:
- an inner flexible tubular member having a first diameter adapted for insertion underneath the eyelids of a patient'"'"'s eye and adapted to extend around the eyeball of a patient;
an outer flexible tubular member having a second diameter greater than said first diameter and being adapted to engage the anterior surface of the eyelid of a patient,a flexible drape of sheet material extending between said inner and outer tubular members; and
means for pumping fluid under pressure into said inner and outer flexible tubular members to inflate said members and draw said drape of sheet material into substantial planar contact with the interior and anterior portions of said eyelids.

Abstract
A surgical drape includes inner and outer flexible tubular members having a flexible drape of sheet material extending between them and a pumping device for pumping fluid into the inner and outer members. Also disclosed is a tool for depositing the surgical drape around the eye of a patient. A method of using the surgical drape as a barrier eye drape includes the steps of inserting the inner tube underneath the eyelids and around the eyeball of the patient, pumping fluid into the inner tube so as to inflate it into engagement with the eyelids and create retaining pressure, depositing the outer tube on the outer surface of the eyelids, pumping fluid into the outer tube so as to inflate it and draw the drape material into substantial planar contact with the interior and anterior portions of the eyelids, thereby retracting the eyelids outwardly and enlarging an opening between them to allow access to the eye for surgical procedures and provide a waterproof seal.

10. A surgical drape for isolating an incision, comprising:
-
an inner flexible tubular membrane having a first diameter adapted for insertion into the body of a patient and circumscribing the interior of said incision, an outer flexible tubular membrane having a diameter greater than said first diameter and being adapted to engage the anterior surface of the patient'"'"'s body around said incision, a flexible drape of sheet material extending between said inner and outer tubular members, and means for pumping fluid under pressure into said inner and outer flexible members to draw said drape into substantial planar contact with the interior and anterior portions of said incision. - View Dependent Claims (11)

12. A method for draping the eye of a patient during ophthalmic surgery, comprising:
-
providing a barrier eye drape with an inner flexible tubular member having a first diameter adapted for insertion underneath the eyelids of a patient'"'"'s eye and adapted to extend around the eyeball of a patient, an outer flexible tubular member having a second diameter greater than said first diameter and being adapted to engage the anterior surface of the eyelid of a patient, a flexible sheet of drape material extending between said inner and outer tubular members, and means for pumping fluid under pressure into said inner and outer flexible members; inserting said inner tubular member underneath the eyelids of the patient'"'"'s eye so as to extend around the eyeball of the patient; pumping fluid into said inner tubular member so as to inflate the inner tubular member into engagement with the eyelids of the patient'"'"' eye such that retaining pressure is created; depositing the outer flexible tubular member on the outer surface of the eyelids; pumping fluid into said outer flexible member so as to inflate said outer member to draw said drape material into substantially planar contact with the interior and anterior portions of said eyelids thereby retracting said eyelids outwardly and enlarging an opening there between; whereby access to the eye for surgical procedures is provided and said inner tubular member provides a waterproof seal.
