Surgical draping system
A draping system provides a continuous sterile field between a patient incision area and one or more medical practitioners. The draping system has a quick release system incorporated into the drape that enables a medical practitioner to separate from the continuous sterile field without disrupting the sterile field around the practitioner or the patient. The draping system may include an abbreviated practitioner gown, a drain and an integral patient incision area or a flap for extending the continuous sterile field around to one or more additional operating room tables. A modular drape and gown system extends the sterile field beyond the operating table allowing practitioners to couple to the extended field. A tent provides an enclosed sterile field useful in mobile or other non operating room surgical environments. Integral lighting and information displays facilitate field surgical procedures.
