Medical isolation devices and methods

A method of using an intubation isolation device by a practitioner on a patient positioned on an operating bed, the method comprising:

• providing a medical isolation device comprising:
• a body including an inner surface and an outer surface, the body also including a first side portion, a second side portion, a back side portion, and a top side portion, wherein a front side edge is formed along a first edge of the first side portion, an edge of the top side portion, and a first edge of the second side portion, wherein a base edge is formed along a second edge of the first side portion, an edge of the back side portion, and a second edge of the second side portion;
• an oxygen port providing passage between the inner surface and the outer surface of the body;
• a suction port providing passage between the inner surface and the outer surface of the body;
• a porthole providing passage between the inner surface and the outer surface of the body,
• a porthole cover that inserts into the porthole, the porthole cover including an outer edge and an inner edge, the inner edge defining a throughway in the porthole cover, wherein, when no pressure is applied to the porthole cover, the cover is biased toward a folded position such that the inner edge comes together to close the throughway, and wherein, when pressure is applied to the porthole cover, the cover unfolds such that the inner edge is drawn apart to open the throughway;
• and
• a drape attached to the body.
• positioning the medical isolation device atop the operating bed such that a head of the patient is positioned within the body of the medical isolation device;
• and
• attaching the drape to the side edge of the body such that a free edge of the drape rests atop a body of the patient;
• connecting a suction tubing to the suction port on the medical isolation device, wherein the suction tubing is connected to a suction device;
• connecting an oxygen tubing to the oxygen port on the medical isolation device, wherein the oxygen tubing is connected to an oxygen source;
• and
• operating the suction device and the oxygen source to create airflow through the medical isolation device and maintain a negative pressure.
