Abstract
Abstract An enclosure which can be sterile for performing surgical procedures and a method for its use is disclosed that protects medical personnel from being infected by the patient and the patient from being infected by the surgical environment. The enclosure consists of a tent defining an isolated cavity and having flexible sides at least portions of which are transparent with connected gloves for accessing tools contained within the isolated cavity, an adhesive assembly for securing the enclosure to a patient and a support structure for supporting the tent. The surgeon can operate on a patient by making an incision through the enclosure, the adhesive assembly and the patient's skin. The incision and, consequently, the patient's body fluids, are all contained within the isolated cavity defined by the enclosure. Since the enclosure is collapsible and inexpensive, the entire structure can be disposed of after the surgery. Moreover, the enclosure can be quite small depending on the nature of the procedure. Thus, the use of the invention greatly reduces the amount of sterilizing procedures and their attendant costs required before and after a surgery is performed.
